Product details

12 ns async SRAM — what it means for the bus

The CY7C1021CV33-12ZXC is a 1 Mbit asynchronous SRAM organized as 64K x 16 bits, with a 12 ns access time. It operates from a 3V to 3.6V supply and uses a parallel interface.

Commercial temperature — indoor use only

Rated 0°C to 70°C, this part is intended for commercial equipment in climate-controlled environments — office peripherals, telecom line cards, test equipment, or consumer electronics. It is not specified for automotive, industrial, or outdoor applications where the ambient temperature can drop below freezing or exceed 70°C.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1021CV33-12ZXC?

No official pin-compatible second source or successor is listed in the lifecycle record. However, the 44-TSOP II async SRAM footprint is widely used; parts from ISSI (e.g., IS61LV1024-12T) or Alliance Memory (AS7C1024B-12TIN) are common drop-in candidates — verify pinout and timing compatibility against your design before ordering.

What package does CY7C1021CV33-12ZXC use?

It comes in a 44-TSOP II (0.400", 10.16 mm width) surface-mount package, supplied in Tray format.

What technology is CY7C1021CV33-12ZXC?

It is an asynchronous SRAM — volatile memory with a parallel interface, organized as 64K x 16 bits.
