70V35数据手册集成电路（IC）的存储器规格书PDF

描述 Description

The 70V35 is a high-speed 8K x 18 Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.

特性 Features

True Dual-Ported memory cells which allow simultaneous reads of the same memory location
Separate upper-byte and lower-byte control for multiplexed bus compatibility
70V35 easily expands data bus width to 36 bits (32 bits) or more
BUSY and Interrupt Flag
On-chip port arbitration logic
Full on-chip hardware support of semaphore signaling between ports
Fully asynchronous operation from either port
LVTTL-compatible, single 3.3V (±0.3V) power supply
Available in a 100-pin TQFP package
Industrial temperature range (-40C to +85C) is available
