Detailed Description

64 Kbit dual-port asynchronous SRAM organized as 8K x 8, 25 ns access time, 5 V supply, parallel interface, commercial temperature range, in 64‑TQFP (14 x 14 mm). Ideal for fast, shared memory between two processors or logic blocks.

Key Features

Memory size: 64 Kbit (8K x 8 organization)

Technology: Dual-port, asynchronous SRAM (volatile)

Access time: 25 ns (read)

Write cycle time: 25 ns

Interface: Parallel, byte-wide (8-bit)

Supply voltage: 4.5 V to 5.5 V

Operating temperature: 0°C to 70°C (TA, commercial)

Package: 64‑TQFP / 64‑LQFP, 14 x 14 mm body, surface-mount

Mounting type: SMD/SMT

Base product number: CY7C144

RoHS status: Non-compliant (leaded)

Key Advantages

True dual-port access allows two masters to share memory without wait states in typical use cases

Very low latency (25 ns) for time-critical designs

5 V operation suits legacy and mixed-voltage systems

Simple, direct parallel interface reduces glue logic and firmware complexity

Mature, proven device family widely used in networking and industrial designs

Packaging

Shipment packaging: Bulk

IC package type: 64‑TQFP (also referred to as 64‑LQFP)

Body size: 14 x 14 mm nominal

Pin pitch: typically 0.8 mm for 64‑TQFP/LQFP (verify in datasheet for exact drawing)

Pin count and configuration: 64 leads with parallel bus signals for dual-port SRAM operation

Materials: Molded epoxy package with copper alloy leadframe; matte tin/lead finish typical for non‑RoHS devices

Thermal characteristics: Standard for 64‑TQFP; ensure adequate airflow and follow JEDEC reflow/derating guidelines (see datasheet for θJA/θJC and power dissipation)

Electrical properties (from specs): Vcc 4.5–5.5 V, 25 ns access, 25 ns write cycle, commercial temp 0–70°C, parallel I/O tri‑state bus behavior

Lifecycle

Status insight: This is a mature, legacy 5 V dual‑port SRAM family from Cypress (now Infineon). Availability can be limited and status may vary by region and date code. Many similar 5 V dual‑port SRAMs are NRND/EOL in the market.

Recommended action: Check current lifecycle and stock with Y-IC. We can source available lots or propose compatible options.

Potential alternatives (functionally similar 8K x 8 dual‑port asynchronous SRAM; verify pinout, timing, voltage, and features against your design):

- Cypress/Infineon CY7C144 family speed/grade variants (same base family, different access times)

- Renesas (IDT) 7130/70Vxx dual‑port SRAM families in 8K x 8 class

- ISSI dual‑port SRAM families (e.g., IS64/IS65 series with 8K x 8 options)
