The DCAM (DRAM Controller and Address Multiplexer) ASIC provides the address multiplexers and RAS/CAS/WRITE control for the DRAM as well as data control for the ECDM.

The ECDM (Error Correction and Data Multiplexer) ASIC multiplexes between four data paths on the DRAM array. Since the device handles 16 bits, four such devices are required on the MVME197LE to accommodate the 64-bit data bus of the MC88110 microprocessor. Single-bit error correction and double-bit detection is performed in the ECDM.

The PCCchip2 (Peripheral Channel Controller) ASIC provides two tick timers and the interface to the LAN chip, the SCSI chip, the serial port chip, the printer port, and the BBRAM (Battery Backup RAM).

The VMEchip2 ASIC provides a VMEbus interface. The VMEchip2 includes two tick timers, a watchdog timer, programmable map decoders for the master and slave interfaces, and a VMEbus to/from the local peripheral bus DMA controller, a VMEbus to/from the local peripheral bus non-DMA programmed access interface, a VMEbus interrupter, a VMEbus system controller, a VMEbus interrupt handler, and a VMEbus requester.

Local peripheral bus to VMEbus transfers can be D8, D16, or D32. VMEchip2 DMA transfers to the VMEbus, however, can be 64 bits wide as Block Transfer (BLT).

Features

These are some of the major features of the MVME197LE single board computer:

❏MC88110 RISC Microprocessor

❏32 or 64 megabytes of 64-bit Dynamic Random Access Memory (DRAM) with error correction

❏1 megabyte of FLASH memory

❏Six status LEDs (FAIL, RUN, SCON, LAN, SCSI, and VME)

❏8 kilobytes of Static Random Access Memory (SRAM) and Time of Day (TOD) clock with Battery Backup RAM (BBRAM)

❏Two push-button switches (ABORT and RESET)
