The Micro64/128 is an industrial-oriented controller designed around the ATmega64/128 AVR microcontrollers. It incorporates 29 digital inputs/outputs, analog inputs, real-time clock, a serial boot loader and utilities to make it easier to use the peripherals. Micro64/128 comes in a single 1.5 -cubic-inch encapsulated package that consumes roughly 275 mW.

The Micro64/128 utilizes a pair of communication line drivers to allow several types of serial communication. RS-232A, RS-422, and RS-485 protocols are available for one of the two serial ports. With a 16MHz-system clock, the Micro64/Micro128 has the ability to communicate serially at baud rates up to 250Kbps. This becomes beneficial when time is a factor. SPI and I2C communications are also available.

In addition to the 8-channel-10-bit analog-to-digital converter supplied by the ATmega64/ATmega128, the Micro64/128 optionally offers a 2-channel-12-bit analog-to-digital converter.

The Micro64/128 has 29 bi-directional bit-programmable, digital I/O lines capable of sinking/sourcing 20mA.

Programs for the Micro64/128 can be created in assembly, BASIC or C programming languages.
