Broad ecosystem and application notes for easy design-in

Packaging

Type: 64-TQFP (also referenced as 64-LQFP), surface-mount

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

Size: 14 mm x 14 mm body, low-profile quad flat package

Pin configuration: 64 leads; separate address/data/control pins per port; typical signals include A[0..12], DQ[0..7], CE, OE, R/W, and arbitration/flag pins (e.g., BUSY/INT/Semaphore where applicable)

Thermal characteristics: Designed for -40°C to +85°C ambient operation; QFP form factor supports standard PCB thermal dissipation; use adequate copper and airflow for best results

Electrical properties: 4.5–5.5 V Vcc; CMOS/TTL-compatible I/O; 15 ns access and write cycle; tri-state outputs; parallel asynchronous interface

Lifecycle

Current status: Active and widely used in industrial designs; not near discontinuation based on publicly available information

Equivalent and alternative models (verify pinout, timing, and features for your design):

- Same family, different speed/packaging:

- CY7C144E-15AXI (tray packaging)

- CY7C144E-12AXI / CY7C144E-12AXIT (12 ns)

- CY7C144E-20AXI / CY7C144E-20AXIT (20 ns)

- Closely related Cypress/Infineon variants:
