CY7C960

CY7C961

Low Cost VMEbus Interface

Controller Family

Features

Functional Description

• 80-Mbyte-per-second block transfer rates

• All VME64 transactions provided, including A64/D64,

A40/MD32 transfers

• Auto Slot ID

• CR/CSR space

The CY7C960 Slave VMEbus Interface Controller provides the

board designer with an integrated, full-featured VME64 inter-

face. This 64-pin device can be programmed to handle every

transaction defined in the VME64 specification. The CY7C961

is based upon the CY7C960: additional features include Re-

mote Master capability whereby the CY7C961 can be com-

manded to move data as a VMEbus master. The CY7C961 is

packaged in a 100-pin outline.

• All standard (Rev C)VMEbustransactions implemented

• VMEbus Interrupter

• No local CPU required

The CY7C960 contains all the circuitry needed to control large

DRAM arrays and local I/O circuitry without the intervention of

a local CPU. There are no registers to read or write, no com-

plex command blocks to be constructed in memory. The

CY7C960 simply fetches its own configuration parameters

during the power-on reset period. After reset the CY7C960

responds appropriately to VMEbus activity and controls local

circuitry transparently.

• Programmable from VMEbus, serial PROM, or local bus

• DRAM controller, including refresh

• On-chip DMA controller

• Local I/O controller

• Flexible VMEbus address scheme

• User-configured VMEbus response

• 64-pin TQFP, 10x10mm (CY7C960)

• 100-pin TQFP, 14x14mm (CY7C961)
