Product details

What this 1 Mbit asynchronous SRAM brings to the board

The Infineon CY7C1021DV33-10ZSXIT is a 1 Mbit asynchronous SRAM organized as 64K x 16 bits, with a 10 ns access time and a parallel interface. It operates from a 3V to 3.6V supply and is rated for the industrial temperature range of -40°C to 85°C, making it suitable for embedded systems that need fast, volatile data storage without a clock — think network processors, industrial controllers, or test equipment that cache lookup tables or packet buffers. The 44-TSOP II footprint is a common SRAM package, so layout reuse across board spins is straightforward.

10 ns access time — timing margin matters

Active production — no end-of-life scramble

The CY7C1021DV33-10ZSXIT is listed as Active, so Infineon is still manufacturing it.

Frequently asked questions

What is the access time of CY7C1021DV33-10ZSXIT?

The access time is 10 ns, which is the time from address valid to data valid on a read cycle. This matches a 100 MHz bus without wait states.

What is the memory organization of CY7C1021DV33-10ZSXIT?

It is organized as 64K words by 16 bits, giving a total of 1 Mbit. The 16-bit data bus is parallel.

What is the supply voltage range for CY7C1021DV33-10ZSXIT?

The supply voltage range is 3V to 3.6V, making it a 3.3V nominal part. It is not compatible with 5V or 2.5V rails without level translation.

What package does CY7C1021DV33-10ZSXIT come in?

It is supplied in a 44-TSOP II package (0.400" body width, 10.16 mm), surface-mount. The supplier device package is 44-TSOP II.
