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
the operational sections of the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns
maximum, and is limited to < 20mA for the period of VTERM > Vcc + 10%


Description

The IDT71342 is a high-speed 4K x 8 Dual-Port Static RAM with full on-chip hardware support of semaphore signalling between the two ports. The IDT71342 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 by CE and SEM, 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 IDT71342 typically operates on only 700mW of power. Low-power (LA) versions offer battery backup data retention capability, with each port typically consuming 200µW from a 2V battery. The IDT71342 is packaged in either a 64-pin TQFP or a 52-pin PLCC.
