Product details

256 Kbit asynchronous SRAM — 15 ns access time

The CY7C199-15ZC: This part uses a 28-TSOP I surface-mount package.

Lifecycle — obsolete, sourced through independent distribution

Cypress (now part of Infineon) has discontinued this specific variant. For a production BOM, qualifying a pin-compatible second source is advisable.

15 ns — what it buys on the bus

The 15 ns access time matches the write cycle time.

This is a legacy fine-pitch surface-mount footprint, common in the late-1990s through mid-2000s.
