Standard 64-pin TQFP footprint

Key Advantages

Enables simultaneous data sharing between two processors or controllers

Simplifies inter-processor communication without complex arbitration logic

Low latency read/write for time-critical paths

Drop-in friendly for many 5V legacy designs

Robust operation over industrial temperature range

Proven Cypress dual-port SRAM architecture for reliability

Packaging

Type: 64-pin TQFP / LQFP, low-profile, plastic molded

Material: Standard epoxy-molded plastic with metal leadframe

Size: 14 mm x 14 mm body (supplier device package), low-profile height

Pin configuration: 64 leads around four sides; separate address, data, and control pins for each port (A and B); typical signals include CE/CS, OE, WE, and port-specific control lines

Thermal characteristics: Qualified for -40°C to +85°C ambient; use standard PCB copper for heat spreading; follow JEDEC reflow guidelines

Electrical properties: 5V-only operation (4.5V–5.5V); 15 ns access; asynchronous timing; parallel 8-bit data bus per port; 13 address lines per port for 8K depth

Lifecycle

Status: Mature legacy product; availability can vary by region and date codes; RoHS non-compliant may limit use in some regions

Alternatives and equivalents: Specific pin-compatible alternates are application-dependent and may vary by speed grade and package within the CY7C144 family
