7140LA55CB - Renesas Electronics

Description: The 7140 is a high-speed 1K x 8 Dual-Port Static RAM designed to be used as a "SLAVE" Dual-Port RAM together with the 7130 "MASTER" Dual-Port in 16-bit-or-more word width systems which would result 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. Military grade product in compliance with MIL-PRF-38535 QML is available.
