摘要

设计了一种新的高性能1mb (64K X 16) EPROM (NM27P6841)，该EPROM结合了与摩托罗拉68040和68EC040微处理器的同步无胶接口。90 ns的初始访问时间和30 ns的突发访问时间允许在4-1-11总线周期@ 33Mhz中最多16字节的“突发”访问。这使得总线带宽性能比高性能8位eprom提高了128%。此外，它提供了一种成本低于过去使用的“SRAM阴影”的系统解决方案。

A Synchronous 1Mb (64k X 16) Burst EPROM

A new, high performance 1 Mb( 64K X 16 ) EPROM (NM27P6841) incorporating a synchronous, glueless interface to the Motorola 68040 and 68EC040 microprocessors, has been designed. The 90 ns initial access time and the 30 ns burst access time allow up to a 16 byte “burst” access in 4-1-11 bus cycles @ 33Mhz. This improves the bus bandwidth performance by 128% over high performance 8-bit EPROMs. In addition, it provides a system solution at a cost lower than “SRAM shadowing” used in the past.
