Pin configuration overview:

- 36-bit data bus DQ[0..35]

- Address pins for 2M depth

- Control pins typical of synchronous burst SRAM (CLK, ADV, CE, OE, WE, byte write enables BWx, sleep ZZ, etc.)

Thermal characteristics:

- Operating ambient temperature 0°C to 70°C

- Use good PCB copper and airflow for heat spreading; consult datasheet for thermal resistance and power dissipation guidance

Electrical properties:

- Vcc 3.135 V to 3.6 V

- Clock 117 MHz

- Access time 7.5 ns

- LVTTL-compatible I/O signaling

Lifecycle

Status: Part of a mature Cypress/Infineon NoBL SRAM family. Availability can vary by region and date. Not broadly indicated as end-of-life in general channel checks, but lifecycle status can change.

Same-family alternatives (speed grade variations, similar pinout):

- CY7C1471BV33-133AXC (133 MHz)

- CY7C1471BV33-167AXC (167 MHz)

Same series with different bus widths (not pin-compatible, but close functional alternatives depending on design):

- CY7C1470BV33 (2M x 18)

- CY7C1473BV33 (2M x 72)

Cross-vendor ZBT/NoBL-type 2M x 36, 3.3 V synchronous SRAMs may be applicable depending on timing and pinout. For verified, drop-in or near-drop-in equivalents, please contact our sales team via the Y-IC website for a curated list and technical cross-check.
