70V35
Description
The IDT70V35/34 (IDT70V25/24) is a high-speed 8/4K x 18 (8/4K x16) Dual-Port Static RAM. The IDT70V35/34 (IDT70V25/24) is designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit (32-bit) or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic.

- Separate upper-byte and lower-byte control for multiplexed bus compatibility
- IDT70V35/34 (IDT70V25/24) easily expands data bus width to 36 bits (32 bits) or more using the Master/Slave select when cascading more than one device
- M/S = VIH for BUSY output flag on Master M/S = VIL for BUSY input on Slave
- BUSY and Interrupt Flag
- On-chip port arbitration logic
- Full on-chip hardware support of semaphore signaling between ports
- Fully asynchronous operation from either port
