MVME133 Series

The MVME133 is an intelligent single-board processor module containing both the MC68020 microprocessor and the MC68881 coprocessor. The main features of the MVME133 are as follows. • Double-high/single-wide VMEboard • Address 24/Data 32 (A24/D32) VMEbus master (A24/D16 compatible) • MC68020 Microprocessor with 32-bit address and data, 12.5 MHz (MVME133) or 16.67 MHz (MVME133-1) • MC68881 Floating Point Coprocessor, 12.5 MHz (MVME133) or 16.67 MHz (MVME133-1) • 1Mb of shared local Dynamic RAM, 32-bits wide, accessible from VMEbus • Four 28-pin JEDEC sockets for ROMs/PROMs/EPROMs/EEPROMs (in two banks, each 16-bits wide) (total 256Kb maximum) • Three 8-bit programmable timers for tick and watchdog functions • Time-of-day clock/calendar (real-time clock) (MM58274A) • Front panel asynchronous DB25 serial debug RS-232C port (on MC68901 MFP) • Dual multiprotocol (synchronous/asynchronous) serial ports (Z8530) – RS-232C (port B) – RS-485/RS-422 (port A) • VMEbus system controller functions with level-three arbiter • Single level bus requester (level jumper selcetable) • VMEbus interrupter • VMEbus interrupt handler for all seven levels • Front panel RUN, HALT, and Fail status LEDs • Front panel RESET and ABORT switches • Remote reset through edge connector P2 • Five-position software-readable header; part of the Module Status Register (MSR)
