Product details

The Infineon CY7C1059DV33-10ZSXI is a 8 Mbit asynchronous SRAM organized as 1M x 8, with a 10 ns access time and a parallel interface. It operates from 3 V to 3.6 V and is rated for -40°C to 85°C, making it suited for industrial-temperature applications like factory automation controllers, telecom line cards, and test equipment that need fast, byte-wide scratchpad memory.

The 10 ns access time and 10 ns write cycle time allow back-to-back read or write cycles at full speed.

The 44-TSOP II package (0.400", 10.16 mm width) is a common SRAM footprint; verify that your PCB layout matches the 44-pin TSOP II land pattern before committing the BOM.

The CY7C1059DV33-10ZSXI is marked as EOL hot, meaning Infineon has announced end-of-life.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C1059DV33-10ZSXI?

A pin-compatible alternative would be another 8 Mbit asynchronous SRAM in the same 44-TSOP II package with a 10 ns access time and 3 V to 3.6 V supply. Check the Infineon CY7C1059 family for other density or speed options.
