IDT7142SA

The IDT7142SA are high-speed 2K x 8 Dual-Port Static RAMs. The IDT7142SA is designed to be used as a standalone 8-bit Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the IDT7142 "SLAVE" Dual-Port in 16-bit-ormore word width systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-or-more-bit memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

Both devices provide two independent ports with separate control, address, and l/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down feature, controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.

Fabricated using IDT's CMOS high-performance technology, these devices typically operate on only 550mW of power. Low-power (LA) versions offer battery backup data retention capability, with each Dual-Port typically consuming 200mW from a 2V battery.

The IDT7142SA devices are packaged in a 48-pin sidebraze or plastic DIPs, 48-pin LCCs, 52-pin PLCCs, and 48-lead flatpacks. Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
