16Mbit async SRAM with 15 ns access — fits 1.8 V core logic buses
The CY7C1061G18-15ZXI is a 16Mbit asynchronous SRAM organized as 1M x 16, with a 15 ns access time. This speed grade keeps the read cycle within the timing budget of a 66 MHz bus without wait states — the 15 ns window covers address-to-data valid, so the controller samples the bus at the next rising edge. Supply voltage spans 1.65 V to 2.2 V, matching 1.8 V core logic rails common in networking and industrial controllers. The wide tolerance absorbs a 10 % droop on a 1.8 V rail without losing data integrity. This suits outdoor telecom cabinets, factory-floor PLC racks, and engine-bay controllers where ambient heat cycles exceed commercial limits.
Package and board-fit — 48-TSOP I footprint
Housed in a 48-TFSOP (0.724", 18.40 mm width) — the industry-standard 48-TSOP I footprint. Supplied in a Tray — the standard handling format for volume pick-and-place.
Active lifecycle — sourcing posture for BOM planning
The base product number CY7C1061 covers the 16Mbit asynchronous SRAM family. If a future BOM revision requires a different package or temperature grade, the family shares the same die and interface — the migration path stays within the same datasheet.
