10 ns asynchronous SRAM for the 3.3 V bus
The 10 ns access time means this SRAM can serve a fast bus without wait states in most 33 MHz to 50 MHz memory controllers, provided the controller's output hold time and setup budget are respected.
Package and footprint — 48-VFBGA
The CY7C1021DV33-10BVXI comes in a 48-ball VFBGA (6x8 mm) package. The supplier device package is 48-VFBGA (6x8).
Supply voltage — 3.3 V only, not 5 V tolerant
It is not a 5 V device — do not connect it to a 5 V supply or 5 V logic outputs without level translation. The I/O pins are referenced to VCC; applying 5 V to any pin will exceed the absolute maximum ratings and damage the part.
It is ROHS3 compliant, meaning it meets the latest EU RoHS exemption limits.
