The Motorola MVME133A-20 is a double-high, single-board MPU module designed for VMEbus systems, offering versatile A32/D32 or A24/D32 data and address configurations. Powered by the MC68020 microprocessor, it provides 32-bit data and address handling, along with 1 MB of shared local dynamic RAM accessible from the VMEbus. Four 28-pin JEDEC sockets support ROM, PROM, EPROM, or EEPROM memory expansions up to 256 KB, providing flexible firmware options.
Equipped with robust serial communication interfaces, the MVME133A-20 features a front panel asynchronous DB-25 debug port, dual multiprotocol serial ports supporting RS-485/RS-422A and RS-232C, as well as three 8-bit programmable timers for tick and watchdog functions. The onboard time-of-day clock/calendar (MM58274A) ensures accurate real-time operation for time-sensitive industrial applications.
As a system controller module, the MVME133A-20 provides VMEbus arbitration, interrupter functions with level 3 status ID, and interrupt handling for up to seven VMEbus levels. Front panel indicators and switches, including RUN, HALT, FAIL LEDs, and RESET/ABORT switches, enhance operational monitoring and control, while remote reset capability is supported via edge connector P2.
Ideal for industrial automation, robotics, and other real-time control applications, the MVME133A-20 can be optionally paired with MVME133BUG or MMME133ABUG debug monitor firmware to provide a comprehensive suite of onboard diagnostics, bootstrap loading, and assembly/disassembly tools. Its robust design ensures reliable operation in environments from 0° to 55°C and relative humidity of 5–90% non-condensing.
