MOTOROLA MVME162 Embedded Controller

MOTOROLA MVME162 Embedded Controller

DESCRIPTION

The MVME162 is a double-high VMEmodule equipped with an MC68LC040 or optional MC68040 microprocessor. (The MC68040 microprocessor has a floating-point coprocessor; the MC68LC040 does not.)

The MVME162 has 1MB, 4MB, or 8MB of parity-protected DRAM; 512KB SRAM (with battery backup); a TOD clock (with battery backup); an optional LAN Ethernet transceiver interface with DMA, two serial ports (EIA-232-D and EIA-232-D/EIA-530); six tick timers with watchdog timer(s); optional SCSI bus interface with DMA; VMEbus interface (local bus to VMEbus/VMEbus to local bus, with A16/A24/A32, D8/D16/D32 bus widths and a VMEbus system controller).

Features

Features of the MVME162 include: 

❏ 25MHz 32-bit Microprocessor: either an MC68LC040 Enhanced 32-bit Microprocessor with 8KB of cache and MMU, or an optional 25MHz MC68040 32-bit Microprocessor with 8KB of cache, MMU, and FPU 

❏ 1MB, 4MB, or 8MB of shared Dynamic Random Access Memory (DRAM) with programmable parity 

❏ 512KB of Static Random Access Memory (SRAM) with battery backup 

❏ One JEDEC standard 32-pin PLCC EPROM socket (EPROMs may be shipped separately from the MVME162) 

❏ 1MB Flash memory: either one Intel 28F008SA (for older boards) or four Intel 28F020s (for newer boards) 

❏ Four 32-bit programmable timers and programmable Watchdog Timer (MCchip) 

❏ Two 32-bit programmable timers and programmable Watchdog Timer (optional VMEchip2) 

❏ 8K by 8 Non-Volatile Random Access Memory (NVRAM) and Time of Day (TOD) clock with battery backup (Thompson MK48T08) 

❏ Input/Output 

– Two serial ports (one EIA-232-D DCE; one EIA-232-D or EIA-530 DCE/DTE) 

– Serial port controller (Zilog Z85230)

– Optional LAN Ethernet transceiver interface with 32-bit local bus DMA (Intel 82596CA controller) 

– Four MVIP IndustryPack interfaces 

❏ VMEbus interface (VMEchip2)—non-VMEbus version optional 

– VMEbus system controller functions 

– VMEbus interface to local bus (A24/A32, D8/D16/D32 (D8/D16/D32/D64BLT) (BLT = Block Transfer) 

– Local bus to VMEbus interface (A16/A24/A32, D8/D16/D32) 

– VMEbus interrupter

– VMEbus interrupt handler 

– Global CSR for interprocessor communications 

– DMA for fast local memory-VMEbus transfers (A16/A24/A32, D16/D32[D16/D32/D64BLT]) 

❏ Switches and Light-Emitting Diodes (LEDs) 

– Two pushbutton switches (ABORT and RESET) 

– Eight LEDs (FAIL, STAT, RUN, SCON, LAN, FUSE, SCSI, and VME)
