Description



Features:

M/S = VIH for BUSY output flag on Master, M/S = VIL for BUSY input on Slave
Interrupt Flag
On-chip port arbitration logic
Full on-chip hardware support of semaphore signaling between ports
Fully asynchronous operation from either port
Separate upper-byte and lower-byte controls for multiplexed bus and bus matching compatibility
TTL-compatible, single 5V (±10%) power supply
Available in a 100-pin TQFP
Industrial temperature range (40°C to +85°C) is available for selected speeds
True Dual-Ported memory cells which allow simultaneous reads of the same memory location
High-speed access
Commercial: 15/20ns (max.)
Low-power operation
IDT7037L
Active: 1W (typ.)
Standby: 1mW (typ.)
 Dual chip enables allow for depth expansion without
external logic
IDT7037 easily expands data bus width to 36 bits or
more using the Master/Slave select when cascading more
than one device

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 + 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 IDT7037L is a high-speed 32K x 18 Dual-Port Static RAM. The IDT7037L is designed to be used as a stand-alone 576K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 36-bit or wider memory system applications results in full-speed, errorfree operation without the need for additional discrete logic.

This IDT7037L 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. An automatic power down feature controlled by the chip enables (CE0 and CE1) permit the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using IDT's CMOS high-performance technology, these devices typically operate on only 1W of power. The IDT7037 is packaged in a 100-pin Thin Quad Flatpack (TQFP).
