IDT7024S/L

HIGH-SPEED

4K x 16 DUAL-PORT

STATIC RAM

Integrated Device Technology, Inc.

more than one device

FEATURES:

• M/S = H for BUSY output flag on Master

M/S = L for BUSY input on Slave

• Busy and Interrupt Flags

• On-chip port arbitration logic

• Full on-chip hardware support of semaphore signaling

between ports

• True Dual-Ported memory cells which allow simulta-

neous access of the same memory location

• High-speed access

— Military: 20/25/35/55/70ns (max.)

— Commercial: 15/17/20/25/35/55ns (max.)

• Low-power operation

• Devices are capable of withstanding greater than 2001V

electrostatic discharge.

— IDT7024S

Active: 750mW (typ.)

• Fully asynchronous operation from either port

• Battery backup operation—2V data retention

• TTL-compatible, single 5V (±10%) power supply

• Available in 84-pin PGA, 84-pin quad flatpack, 84-pin

PLCC, and 100-pin Thin Quad Plastic Flatpack

• Industrial temperature range (–40°C to +85°C) is avail-

able, tested to military electrical specifications

Standby: 5mW (typ.)

— IDT7024L

Active: 750mW (typ.)

Standby: 1mW (typ.)

• Separate upper-byte and lower-byte control for

multiplexed bus compatibility

• IDT7024 easily expands data bus width to 32 bits or

more using the Master/Slave select when cascading
