70V27中文资料32K x 16 3.3V Dual-Port RAM数据手册Renesas规格书

描述 Description

The 70V27 is a high-speed 32K x 16 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 32-bit or wider memory system applications resulting in full-speed, error-free operation without the need for additional discrete logic. An automatic power down feature controlled by the chip enables (CE0 and CE1) 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 access of the same memory location
Separate upper-byte and lower-byte control for bus matching capability
Dual chip enables allow for depth expansion without external logic
70V27 easily expands data bus width to 32 bits or more
Busy and Interrupt Flags
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 100-pin TQFP and 144-pin fpBGA packages
Industrial temperature range (-40C to +85C) is available
