Description
The IDT70V35/34/25/24 is a high-speed, low-power, dual-port static RAM (SRAM) with a capacity of 8/4K x 18/16 bits. It features true dual-ported memory cells that allow simultaneous reads of the same memory location. The SRAM operates from a single 3.3V (±0.3V) power supply and is available in a 100-pin TQFP (IDT70V35/34 & IDT70V25/24) and 84-pin PLCC (IDT70V24) package.
Features
True dual-ported memory cells
High-speed access:
IDT70V35: 15ns (max.)
IDT70V34: 15ns (max.)
IDT70V25: 15/35ns (max.)
IDT70V24: 15/35/55ns (max.)
Low-power operation:
IDT70V35/34: Active: 415mW (typ.), Standby: 660μW (typ.)
IDT70V25/24: Active: 400mW (typ.), Standby: 3.3mW (typ.)
IDT70V25/24: Active: 380mW (typ.), Standby: 660uW (typ.)
Separate upper-byte and lower-byte control for multiplexed bus compatibility
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
LVTTL-compatible
Industrial temperature range (-40°C to 85°C) available for selected speeds
Green parts available
Applications
High-speed data buffering
Cache memory
Shared memory between multiple processors
Semaphore signaling
Interrupt handling
FIFO buffers
Stack memory
