Product details

The CY7C109B-15ZC is a 1Mbit asynchronous SRAM organized 128K x 8 with 15 ns access time. Supply range is 4.5 V to 5.5 V.

15 ns access time — what it means for the bus

15 ns address-to-data valid.

Commercial temperature — deployment boundary

Rated 0°C to 70°C ambient. That covers indoor office, lab, and telecom central-office environments. Not for unheated enclosures, engine bays, or outdoor cabinets. If the BOM calls for industrial or automotive temperature, this part does not fit — you would need the -15ZI variant (industrial) or a different family entirely.

Frequently asked questions

What is the closest pin-compatible alternative to CY7C109B-15ZC?

No official pin-compatible second source or successor is listed in the available records. Any replacement would need to match the 32-TSOP I footprint, 5 V supply, 15 ns access time, and 128K x 8 organization.
