Product details

The Infineon CY7C0851V-133BBI is a 2 Mbit synchronous dual-port SRAM organized as 64K x 36 bits. The 133 MHz clock rate supports high-speed data buffers in networking gear and base stations.

172-FBGA (15x15) — PCB design considerations

The 172-ball FBGA with 15x15 mm footprint demands a multilayer PCB with via-in-pad or microvia capability. The fine pitch rules out hand-soldering and most rework stations — plan for X-ray inspection and a controlled reflow profile. The package is surface-mount only, consistent with the mounting type.

Frequently asked questions

What is the difference between CY7C0851V and CY7C0851AV?

The 'AV' suffix typically indicates a lower-voltage or enhanced revision from Cypress/Infineon. The CY7C0851V-133BBI runs on a 3.3 V nominal supply; the CY7C0851AV variant may support a wider or lower voltage range. Verify the exact datasheet revision for your timing and voltage requirements.

Is CY7C0851V-133BBI compatible with 3.3V systems?

Yes, the supply range of 3.135 V to 3.465 V is a standard 3.3 V rail with ±5% tolerance. All I/O are 3.3 V compatible, so it interfaces directly with 3.3 V logic families without level shifters.

What is the datasheet for CY7C0851V-133BBI?

The datasheet for the CY7C0851V-133BBI is available from Infineon (formerly Cypress). It covers the full timing parameters, pinout for the 172-FBGA package, and AC/DC characteristics for the 133 MHz synchronous dual-port SRAM family.
