FUNCTIONAL BLOCK DIAGRAM

• Busy and Interrupt Flags

• On-chip port arbitration logic

• Full on-chip hardware support of semaphore signaling

between ports

• Fully asynchronous operation from either port

• Devices are capable of withstanding greater than

2001V electrostatic discharge

• TTL-compatible, single 5V (

±10%) power supply

• Available in ceramic 68-pin PGA, 68-pin PLCC, and

an 80-pin TQFP

• Industrial temperature range (–40

°C to +85°C) is

available, tested to military electrical specifications

DESCRIPTION:

The IDT7016 is a high-speed 16K x 9 Dual-Port Static

RAMs. The IDT7016 is designed to be used as stand-

alone Dual-Port RAM or as a combination MASTER/

SLAVE Dual-Port RAM for 18-bit-or-more wider systems.

FEATURES:

• True Dual-Ported memory cells which allow simulta-

neous access of the same memory location

• High-speed access

— Military: 20/25/35ns (max.)

— Commercial:12/15/20/25/35ns (max.)

• Low-power operation

— IDT7016S

Active: 750mW (typ.)

Standby: 5mW (typ.)

— IDT7016L

Active: 750mW (typ.)

Standby: 1mW (typ.)

• IDT7016 easily expands data bus width to 18 bits or

more using the Master/Slave select when cascading

more than one device

NOTES:

1. In MASTER mode:

BUSY is an output and is a push-pull driver

In SLAVE mode:

BUSY is input.

2.

BUSY outputs and INT outputs are non-tri-stated push-pull drivers.
