Product details

Obsolete — last-time-buy and sourcing reality

Buyers should plan for a one-time last-buy or identify a pin-compatible alternative for long-term supply.

165-FBGA — not a hand-solder part

The 165-ball FBGA (15x17 mm) is a fine-pitch BGA. This is not a part you breadboard or hand-solder with an iron — it requires a reflow oven, solder paste stencil, and X-ray inspection for voiding. The footprint is standard for high-density SRAM; PCB layout should follow Cypress's application note for decoupling and signal integrity at 133 MHz.

Frequently asked questions

What is the replacement for CY7C1441AV33-133BZI?

No official replacement order code is listed in the available records. For a pin-compatible alternative, check the Cypress synchronous SRAM family with the same 165-FBGA footprint and 1M x 36 organization — but verify timing and supply voltage against your design.

What is the voltage range for CY7C1441AV33-133BZI?

The supply voltage range is 3.135V to 3.6V, compatible with standard 3.3V logic.

What is the pinout of CY7C1441AV33-133BZI?

The pinout is defined for the 165-ball FBGA package. Refer to the Cypress datasheet for the full ball map and signal assignments.
