General Info

The MD88 is based on the A-Core with compatible software drivers and C/C++ Evaluation or Development Kits. It offers many of the same features the original AC does with slightly increased physical dimensions.

The MD88 can be integrated into an OEM product as a processor core component. By building your product around the MD88, you reduce the time from design to market introduction, cut development costs, minimize technical risks, and deliver a more reliable product.

Measuring 3.1 x 2.6 x 0.3 inches, the MD88 offers a complete C/C++ programmable computer system with 35 protected high voltage I/Os, and a 16-bit high performance CPU (Am188ES, AMD) operates at 40 MHz system clock with zero-wait-state.

It features up to 512K EPROM/Flash, 512K battery-backed SRAM and 512 bytes serial EEPROM. Two high speed DMA driven serial ports from Am188ES support high speed reliable serial communication up to 115,200 baud supporting 8-bit and 9-bit RS-232 communication with on-board RS-232 drivers. There are three 16-bit programmable timers/counters and a watchdog timer.

Two timers can be used to count or time external events, up to 10 MHz, or to generate non-repetitive or variable-duty-cycle waveforms as PWM outputs. The Pulse Width Demodulation (PWD), a distinctive feature, can be used to measure the width of a signal in both its high and low phases. It can be used in many applications , such as bar-code reading.

A real-time clock (RTC72421, EPSON) provides information on the year, month, date, hour, minute, second, 1/64 second, and an VOFF control signal.

A supervisor chip with power failure detection, watchdog timer, a LED, 5V linear regulators, screw terminals, and pin headers are on board.


Includes 188 40 MHz, 128 KB SRAM, 35 solenoid drivers, RS232 driver, 5V regulator, 2 UARTs, 3 timers/2 PWMs, 32 I/Os, watchdog timer, 512 byte EE. Does not include add-on options, OEM option discounts available.
