Key Advantages

True dual-port architecture enables simultaneous reads/writes from two processors or buses without external arbitration

Fast 15 ns timing supports high-throughput legacy 5V designs

9-bit width simplifies parity or flag handling

Drop-in friendly for many existing systems using Cypress dual-port SRAMs

Reliable brand lineage (Cypress under Infineon) with strong ecosystem support

Packaging

Package type: 80-pin TQFP/LQFP

Body size: 14 x 14 mm; low-profile quad flat package

Material: Molded epoxy encapsulation with copper leadframe

Pin pitch: Typically 0.65 mm (80-pin TQFP/LQFP standard)

Pin configuration (typical for 8K x 9 dual-port):

- Separate address buses for Port A and Port B (13 address lines per port for 8K depth)

- 9 I/O pins per port (D0–D8)

- Independent control per port (CE, OE, R/W; Busy/Interrupt signals on many family parts)

- VCC and GND distributed across multiple pins for stable power and signal integrity

Thermal characteristics:

- Designed for commercial temperature operation (0°C to 70°C)

- Use solid ground plane, adequate copper area, and airflow for best heat dissipation

Electrical properties:

- VCC: 4.5 V to 5.5 V

- CMOS/TTL-compatible I/O levels (typical for 5V dual-port SRAM)

- Asynchronous operation, no external clock required

Shipment packaging: Tray (ideal for automated pick-and-place)

Lifecycle

Current status: Active in many legacy and maintenance programs; production status may vary by speed grade and package

Nearing discontinuation: Not officially indicated here; check with Y-IC for latest status

- Same family, different grades:

- CY7C145-10AXC (10 ns, commercial temp)

- CY7C145-12AXC (12 ns, commercial temp)

- CY7C145-15AXI (15 ns, industrial temp -40°C to +85°C)

- CY7C145-12AXI (12 ns, industrial temp)

- Cross-vendor candidates (subject to full compatibility checks):

- Renesas/IDT 70V24-15 (8K x 8 dual-port SRAM, 5V class, 80QFP variants)

- ISSI IS61D09A-15TQ (8K x 9 dual-port SRAM, 5V, TQFP)

- MoSys/IDT legacy dual-port SRAMs with 8K x 8/9 organizations in 80-pin QFP/TQFP
