NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed VCC +0.5V for more than 25% of the cycle time or 10ns maximum, and is limited to 20mA for the period of VTERM VCC + 0.5V.


Description

The IDT71342LA is an extremely high-speed 4K x 8 Dual-Port  Static RAM with full on-chip hardware support of semaphore signalling between the two ports.

The IDT71342LA provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. To assist in arbitrating between ports, a fully independent semaphore logic block is provided. This block contains unassigned flags which can be accessed by either
side; however, only one side can control the flag at any time. An automatic power down feature, controlled byCE andSEM, permits the on-chip circuitry of each port to enter a very low standby power mode (both CE and SEM High).

Fabricated using IDT's CMOS high-performance technology, this device typically operates on only 500mW of power. Low-power (LA) versions offer battery backup data retention capability, with each port typically consuming 200mW from a 2V battery. The IDT71342LA is packaged in either a 64-pin TQFP, thin quad plastic flatpack, or a 52-pin PLCC.
