Detailed Description

64Kbit dual‑port asynchronous SRAM, organized as 8K x 8, 15 ns access and write cycle, 5 V supply (4.5–5.5 V), parallel interface, commercial temperature 0–70°C, surface‑mount 64‑TQFP (14 x 14 mm), RoHS3 compliant, supplied in Tape & Reel. Base product number CY7C144. Available stock 2677 units

Key Features

Dual‑port SRAM for two independent bus masters

Asynchronous operation for simple timing and fast response

64Kbit capacity, 8K x 8 organization

15 ns access time and 15 ns write cycle time

5 V supply, TTL/CMOS compatible I/O

Parallel interface for easy connection to CPUs, FPGAs, DSPs

64‑TQFP package, surface mount, RoHS3 compliant

Commercial temperature range 0–70°C

Key Advantages

True two‑port memory enables simultaneous access without external arbitration in many designs

Very low latency (15 ns) for real‑time tasks and tight control loops

Simple parallel bus reduces design time and firmware complexity

5 V operation fits legacy and industrial systems

Proven Cypress/Infineon reliability with broad ecosystem support

Packaging

Type Tape & Reel for automated assembly

Package 64‑TQFP (also referenced as 64‑LQFP), body size about 14 x 14 mm, low profile

Material Lead‑free matte‑tin plated copper leadframe with epoxy molding compound (industry standard, RoHS3)

Pin configuration 64 leads, 16 per side, typical pitch about 0.8 mm. Two port groups with separate address, data, and control signals (CE, OE, WE) per port. See datasheet for exact pinout

Thermal characteristics Commercial temperature 0–70°C. Typical thermal resistance for 64‑TQFP is in the range of about 65–90 °C/W in still air (refer to datasheet and board layout for precise values)

Electrical properties Supply 4.5–5.5 V, volatile SRAM, asynchronous timing, TTL/CMOS‑compatible I/O. Fast 15 ns read and write timing

Lifecycle

Status under Infineon may vary by speed grade and package. Many legacy 5 V dual‑port SRAMs have limited production or are designated NRND in some variants. Check current status with Y-IC

Equivalent or alternative models to consider

- Same family and speed/package variants if available CY7C144‑20AXCT, CY7C144‑25AXCT (slower speeds), or different packing options like CY7C144‑15AXC

- Larger or related Cypress/Infineon dual‑port SRAM families CY7C136 (16K x 8), CY7C147 (32K x 8) if capacity upgrades are acceptable

- Renesas (IDT) dual‑port SRAMs with similar function IDT7130 series (8K x 8, 5 V, asynchronous) such as IDT7130SA/LA. Pinouts and timings differ, so verify compatibility
