1. General Description

The MVME1603‑002 is a cost‑optimized, double‑high 6U VMEbus single‑board computer based on the PowerPC 603 RISC microprocessor, designed for embedded applications requiring VMEbus and PCI local bus performance but with reduced memory requirements. It uses the same 66 MHz PowerPC 603 CPU as the MVME1603‑001, with 16 KB instruction and 16 KB data on‑chip caches.
The board follows a modular construction: MVME1600‑001 baseboard + PM603 processor mezzanine + 8 MB non‑ECC DRAM module (vs 64 MB ECC in ‑001). It includes 2 KB battery‑backed CMOS SRAM and a battery‑backed real‑time clock (RTC). Four 32‑pin ROM/EPROM/EEPROM sockets support up to 4 MB of boot/firmware storage; the MVME1603‑002 ships with standard PPCBug firmware preinstalled.
Peripheral interfaces match the MVME1603‑001: four EIA‑232‑D serial ports, a Centronics‑compatible parallel port, onboard 10/100 Mbps Ethernet, PCI local bus (32‑bit, 33 MHz, 132 MB/s), and one PMC expansion slot.
The VMEbus interface supports A16/A24/A32 addressing and D08/D16/D32/D64 data widths, with master/slave operation and system controller functions. The MVME1603‑002 complies with VMEbus Rev C and is VME64 compatible.
