Detailed Description

64Kbit asynchronous dual-port SRAM, organized as 8K x 8

Parallel interface with independent A and B ports for true concurrent access

15 ns access time, 15 ns write cycle

5 V operation (4.5 V to 5.5 V)

Commercial temperature 0°C to 70°C (TA)

Surface-mount 64-pin TQFP/LQFP package, 14 mm x 14 mm body

RoHS3 compliant, lead-free

Base product number CY7C144

Main category: Integrated Circuits (ICs). Subcategory: Memory

In stock quantity: 2537 units (subject to change)

Supplied in tray packaging

Key Features

Dual-port architecture: two independent ports (A and B) can read/write simultaneously

Asynchronous operation: no clock required, simple timing

Fast access: 15 ns read and 15 ns write for low latency

8K x 8 organization: 13-bit address per port, 8-bit data bus per port

Parallel interface: easy connection to MCUs, DSPs, FPGAs

On-chip arbitration: busy/interrupt/semaphore features help manage simultaneous access

CMOS design: low power compared to older bipolar designs

5 V tolerant I/O compatible with TTL/CMOS logic levels

Tri-state outputs for bus sharing

Industrial family options available for wider temperature ranges

Key Advantages

Enables reliable, high-speed communication between two processors or logic domains without complex firmware

Reduces system latency versus shared single-port memory with bus multiplexing

Simplifies inter-processor data sharing using built-in semaphores and busy flags

Proven, mature solution with broad second-source ecosystem in telecom and industrial markets

Straightforward timing makes hardware integration and debug faster

5 V operation fits legacy and long-life platforms

Packaging

Type: 64-pin TQFP/LQFP, industry-standard quad flat package for surface mount

Material: Molded epoxy package with copper leadframe, lead-free plating (RoHS3)

Size: 14 mm x 14 mm body, typical thickness ~1.4 mm (refer to datasheet for exact)

Pin count and pitch: 64 leads, typical 0.8 mm pitch (refer to datasheet for exact)

Pin configuration highlights:

- Port A: A[12:0] address, D[7:0] data, CE, OE, R/W (or WE), BUSY, INT, SEM

- Port B: B[12:0] address, D[7:0] data, CE, OE, R/W (or WE), BUSY, INT, SEM

- Separate control per port allows true concurrent operation

Thermal characteristics: No exposed thermal pad. Use standard PCB copper area and airflow for heat dissipation. Operates within 0°C to 70°C ambient when used per datasheet guidelines

Electrical properties:

- Supply: 4.5 V to 5.5 V

- I/O: TTL/CMOS compatible, tri-state outputs

- Asynchronous timing, 15 ns read/write access

Shipping: Tray (good for automated pick-and-place)

Lifecycle

Status: Mature product family. Some variants may be in limited supply or nearing end-of-life depending on speed grade and package. Check current availability with Y-IC

Direct family variants (same density, similar function; verify pinout/package):

- CY7C144-15AXI (industrial temperature option)

- CY7C144-20AXC (20 ns speed grade, commercial)

- CY7C144-12AXC (12 ns speed grade, if available in your region)

- CY7C144 variants in alternate packages (e.g., TSOP or PQFP), speed grades 12/15/20 ns

Cross-vendor alternatives (8K x 8 dual-port SRAM, 5 V, asynchronous; verify pin compatibility and timing):

- IDT7132LA15 or IDT7132SA15 (Renesas/IDT), 8K x 8, 15 ns

- IDT7132LA20 or IDT7132SA20, 20 ns

Higher-density alternatives within similar Cypress/Infineon dual-port families (if you need more memory; board changes likely):

- CY7C130 series (16K x 8)

- CY7C133 series (32K x 8)

- CY7C136 series (128K x 8)
