Micro/sys announces a new I/O card to our family of PC/104 data acquisition stack-on boards which offers 32 channels of 16-bit analog-to-digital input and 4 channels of 14-bit digital-to-analog output. Designed to meet the need of the new generation of Intel based PC/104 CPUs which no longer have DMA present on the bus, the MPC565 implements First In, First Out (FIFO) registers to organize and pass data back-and-forth over the PC/104 bus. By utilizing the FIFO registers, users gain the advantage of simultaneous read/write functions at convenient intervals without tying up valuable CPU time. Significant attention was given to ensure a low noise analog subsystem which could deliver true 16-bit and 14-bit performance. The rigorous analog input subsystem includes programmable gain amplifiers, programmable low-pass filters, a 16-channel differential input mode (DI), and input overvoltage protection to ±40V, with power on or off. The analog output subsystem includes 1-pole low-pass filters, and output buffers capable of driving cables and other high capatance loads. An on-board EEPROM holds calibration data which is used for installed, end-to-end calibration of input channels.

The popular Autoscan mode in the analog input section adds a wealth of choices to the system designer. Various on-board or external “pacer clocks” can be used to cause periodic conversions to occur without any software intervention. An SRAM-based storage area is used to set the include/exclude control, mode (SE or DI), gain, and low-pass filter knee for each channel, individually. Once initiated, the Autoscan mode proceeds, using a 1024 word FIFO register. FIFO flags can trigger a system IRQ to allow efficient servicing by the program.
The MPC565 also includes 12 general-purpose digital I/O lines. These flexible I/O lines can be individually set as input, output, or inputs that generate an IRQ when they transition from low to high. Fault protection is provided on all 12 digital I/O lines.
Analog input range is ±10.1V or ±5.05V. Analog output range is ±10.1V, and all outputs are set to 0V upon power-up or reset. Input and output accuracy is .02% of full scale across the operating temperature range. The input circuitry will allow sampling of 20V p-p at 35KHz, or 5V p-p at 100KHz. The output circuitry can generate 20V p-p signals at 15KHz. Sample programs and full documentation are provided with the board.
An extended temperature version, the MPC565-ET, is also available. The MPC565-ET has proven hight accuracy from –40°C to +85°C. Both versions of the MPC565 require only a single 5V supply to operate. Line regulation on the 5V input is .001% of full scale.
The MPC565 starts at $440 in single quantity and mid $200’s in OEM quantities. Turn-key development kits ship with the first unit allowing immediate out-of-the-box development. Significant OEM discounts are available on all boards.
