Detailed Description

High-speed true Dual-Port Static RAM, 8K x 16 organization, 35 ns access time. Two independent ports allow simultaneous read/write by two processors with on-chip arbitration and semaphore logic to prevent data conflicts. CMOS technology for low power and high reliability. J-leaded PLCC package for robust board mounting.

Key Features

True dual-port architecture with separate address, data, and control lines for each port

8K x 16 memory density for wider data paths

35 ns access time for fast read/write

On-chip busy arbitration and semaphore flags to manage shared access

Asynchronous operation, no clock required

Byte-enable and separate control signals per port for flexible writes

Fully static operation, no refresh needed

CMOS process for low power and high noise immunity

Pin-compatible family options across speeds and packages

Key Advantages

Simplifies inter-processor communication with shared memory and hardware conflict resolution

Boosts system throughput by allowing concurrent access on both ports

Reduces software overhead thanks to hardware semaphores and busy signals

Stable timing and low latency suitable for real-time systems

Mature, proven architecture widely used in networking, industrial, and embedded designs

Packaging

Type: J-leaded PLCC (commonly referred to as PLCC84 for dual-port SRAM families)

Material: Molded plastic body with copper alloy J-leads, tin finish

Size: Standard PLCC footprint; compact square body suited for high-density boards

Pin configuration: Two identical ports (Port A and Port B). Each port typically includes address lines (~13 for 8K), 16 data lines, chip select, write enable, output enable, busy/semaphore signals, and power/ground pins. Ports are independent and symmetric.

Thermal characteristics: Designed for reliable operation in typical commercial/industrial environments; good thermal cycling robustness due to J-lead package. Typical junction-to-ambient thermal resistance is in the tens of °C/W range depending on board design and airflow.

Electrical properties: 5 V nominal CMOS supply (typical operating range 4.5–5.5 V), 35 ns access time, asynchronous timing, TTL/CMOS-compatible I/O, low standby current due to CMOS design. Noise margins and drive strengths suited for direct MCU/FPGA interface. Refer to datasheet for exact pinout and electrical limits.

Lifecycle

Status: Mature legacy product. Availability can be limited and may vary by speed grade and package. It is not new and may approach NRND or discontinuation depending on sub-variant.

Close alternatives and equivalents:

- Renesas/IDT family: IDT7016S25J, IDT7016S20J, IDT7016S15J (same density, faster speeds); IDT7016Lxx variants (low-power); same-series parts in different packages where available.

- If you need different bus width/capacity but same architecture: IDT7006Sxx (8K x 8), IDT7014Sxx (16K x 8), IDT70216Sxx (64K x 16).

- Cross-vendor families commonly used as drop-in or near-drop-in alternatives in dual-port SRAM designs: Cypress/Infineon CY7C02x dual-port SRAM series (e.g., CY7C024 16K x 8, CY7C026 16K x 16) and ISSI dual-port SRAM series. Match organization, timing, and pinout carefully.
