i o corporation is a manufacturer of programming and automated device handling systems for programmable integrated circuits . the company is headquartered in redmond washington with sales and engineering offices in multiple countries . 1 contents 1 history 2 products 2.1 current 2.2 legacy 2.2.1 model 1 2.2.2 system 29 2.2.3 unifamily 3 mass storage module 4 references 5 external links history edit data i o was incorporated in 1969 . 2 before the ibm pc was introduced the company developed equipment that allowed electronic designers to program the non volatile semiconductor devices with data stored on punched cards or ascii encoded eight level punched paper tape . over the next three decades the company rode the non volatile technology wave as bipolar eprom eeprom nor flash antifuse fram and most recently nand flash devices were introduced by semiconductor vendors . while not manufacturing semiconductors itself data i o s business is the design and manufacture of equipment that transfers data into various non volatile semiconductor devices . these devices commonly are flash memory microcontroller devices and programmable logic devices . products edit current edit introduced in 2000 data i o flashcore technology is optimized for programming of nand and nor based flash devices and flash microcontrollers and is sold in flashpak ps system flx500 and proline roadrunner programmer models spanning engineering to high volume offline and inline just in time manufacturing . data i o provides tasklink for windows software to set up flashcore programmers and specify data sources . in addition they develop software that manages automated and remote programming secures data and manages device serialization . many of these work with tasklink while others are independent software packages . data i o manufactures two device programmers that can accommodate dip through hole devices the plus 48 and the optima . both are aimed at the small relatively low cost desktop programmer engineering market . legacy edit data i o model 29b universal programmer with a unipak 2 model 1 edit one of their first attempts at a universal programmer was the model 1 model 5 ttl sequencer based model 9 microprocessor based and the system 19 introduced in the late 1970s . it utilized interchangeable device sockets and configuration plug in printed circuit cards consisting mainly of resistors diodes and jumpers to allow reading and programming of a variety of memory devices . system 29 edit in the early 1980s the system 29 series emerged . the first model the 29a added user ram and eliminated the need for configuration cards by offering keypad programmable family and pinout codes to configure the programmer . introduced along with the 29a was the unipak a large plug in adapter that featured multiple sizes of zif sockets to reduce the need for changing socket modules . since the unipak was limited to dealing with memory devices an additional accessory series called the logicpak was introduced to handle programmable logic devices pals gals etc. later models featured a series of fixed sockets and an interchangeable socket module in one housing . memory devices up to 40 pins in size could be read or programmed with the simple installation of the appropriate socket module . the 29b chassis could accommodate up to 1mb of user ram . unifamily edit around 1987 data i o introduced the first of the unifamily programmers in the form of the unisite . this was their first engineering programmer to feature software programmable pin drivers a technology that allows any pin of the device socket to be configured through software for power ground or nearly any type of programming waveform . the first model in this line the unisite 40 featured a removable module with a single 40 pin dip zif socket called the site 40 and space to install optional programming adapters to the right of this dip module . such modules included the setsite a module containing eight 40 pin zif sockets to allow gang programming of up to eight identical memory devices and the chipsite an early multi socket module accommodating several sizes of plcc and soic dip packages with clamshell zif sockets . the final successor to the chipsite unit was the pinsite . this featured a universal programming base which could accept a variety of socket adapters including those for chips packaged in pga qfp tsop and many others . there was even a special connection module made available which could through the pinsite s base allow the unisite to serve as the programming source in automated device handlers in factory floor environments . the unifamily was the first series of data i o s programmers to feature a built in user menu . all the programmer required for basic operation was a dumb terminal hooked up via an rs232 serial port . facilities were also provided for computer based remote control via a second serial port . the early unifamily all booted and ran from software stored on 720k floppy diskettes in the case of the unisite or on 1.44 mb floppies in the case of other unifamily members . this software consists of the operator s menu system self test routines and device algorithms . later in production an option for installation of a miniature hard drive was provided see msm or mass storage module below . the unisite is the only programmer that still requires true 720k floppies for non msm operation or updating the msm s software without the aid of external pc based software . the unisite was the flagship model of the unifamily line selling for over 35 000 in a typical configuration and staying in active production for at least 20 years . data i o in an effort to make the unifamily line more attractive to companies with tighter budgets introduced several other programmers utilizing the same pin driver technology as the unisite all selling for typically under 10 000 . these included the model 2900 3900 3980 and 3980xpi . these units varied in capability primarily in terms of the number of pin drivers . the basic 2900 featured 44 drivers while the 39xx series all had 88 . data i o developed a proprietary multiplexing scheme which allowed unifamily programmers equipped with their maximum number of hardware pin drivers to handle devices with up to 240 pins . other differences in the series are minor . models share a common base design and feature the ability to boot and run from floppy diskettes and provide an internal menu . the differences are primarily in features . the unisite less than a year of entering production was revised in the form of a new dip module referred to as the site48 . this adapter had 48 pins in its dip socket and remained the standard for many years . its successor the site48 hs is functionally identical but utilizes solid state switching for the socket pins instead of the electromechanical relays in earlier adapters such as the 2900 and 39xx series . the unisites featured 512k of user ram standard . field installable upgrade kits consisting of a separate memory board an appropriate number of 30 pin simms a mounting bracket and interconnecting cable were made available to upgrade these early units to 1mb or 8mb . the price for the 8mb upgrade kit was around 495 in the mid 1990s . these early kits required considerable labor to install including extensive disassembly of the programmer as the memory board was designed to mount under the main circuit board . in response to these difficulties as well as improvements in available technology the unisite s main circuit board soon received major revisions . these included the removal of most of the dip based dram chips and the addition of two 30 pin memory module sockets on the main board . with these changes upgrading the programmer s available ram became much easier requiring only the removal of the top cover installation of two simms and replacing one pal chip . mass storage module edit the revisions to the unisite main board were done to support a new option . data i o created the mass storage module msm . this consisted of an additional circuit board containing a miniature hard disk drive either a 2.5 inch pata ide device or a pcmcia type iii card drive depending on revision level and appropriate interface circuitry . all the programmer s operating software and device algorithms could be transferred to the msm s drive in less than a half hour obsoleting floppy diskettes . the latest revision is entirely solid state consisting of a single large fpga chip as the board s glue logic an sprom serial programmable read only memory chip containing the fpga s operating code a few sram chips for buffering and a solid state or flash drive . the msm remains an optional field installable module for the 3900 and unisite . unisite programmers require 8mb of user ram and controller board revision 701 2313 00 or higher to utilize this option . in addition the msm requires operating software revisions of 6.6 or above . all 3900 series programmers are msm compatible at the hardware level . successful installation of the msm in a 3900 programmer automatically turns it into the model 3980 . msm adds another option a high speed parallel port interface that supplements the programmer s serial port . in conjunction with a windows based pc and data i o s tasklink software the parallel port greatly enhances the speed of data transfers to and from the programmer . as one example a 1mb data file takes at least two minutes to be transferred into or out of a unifamily programmer via the serial port at its highest available speed 19200 baud . the same file transferred with the parallel port s help takes around 30 40 seconds . any unifamily programmer with xpi after its name unisite xpi 3980 xpi already has the msm and parallel port options installed as standard equipment . these programmers represent the end of the unifamily line and although no longer in production are fully supported . references edit data i o corporation redmond wa usa . daio profile data i o corporation stock yahoo finance . external links edit corporate webpage data i o germany
