This is the final procurement window before the part is discontinued — no further factory orders will be accepted after the LTB date passes. If this SRAM is socketed in an active design, now is the time to secure lifetime buy quantities or validate a drop-in replacement.
16Mbit asynchronous SRAM — 1M x 16, 15 ns access
The Infineon CY7C1061G18-15ZSXIT is a 16Mbit asynchronous SRAM organized as 1M words by 16 bits. It operates from a 1.65V to 2.2V supply rail, aligning with 1.8V-core logic families and low-power processor buses. Packaged in a 54-TSOP II (0.400" body width), this is the standard footprint for high-density asynchronous SRAMs in this density tier — pin-compatible with the broader 54-pin TSOP II SRAM ecosystem.
Supply rail and interface — design checklist
The 1.65V to 2.2V supply range means this part runs from a 1.8V nominal rail. The parallel interface uses standard SRAM control signals (CE, OE, WE) — no SDRAM-style refresh or command sequencing. The 15 ns access time gives a 66 MHz equivalent random-read rate, which is the figure to budget in your timing closure analysis. Surface-mount assembly on the 54-TSOP II footprint. Standard reflow profile for TSOP packages applies. The Tape & Reel (TR) shipping medium feeds pick-and-place without a tube-to-reel transfer step.
