Product details

12 ns access — timing margin for a 5 V bus

The CY7C1020B-12ZXC: 512Kbit asynchronous SRAM organized as 32K x 16 bits, with a 12 ns access time.

Obsolete — no official replacement listed

44-TSOP II — footprint for legacy memory slots

Housed in a 44-TSOP (0.400", 10.16 mm width) surface-mount package, this SRAM uses the industry-standard JEDEC pinout for 32K x 16 asynchronous SRAMs.

Frequently asked questions

Is CY7C1020B-12ZXC compatible with 5V logic?

Yes. No level shifting is required on the address, data, or control lines when interfacing with a 5 V bus.
