MoBL® SRAM for low-power, high-speed cache and buffer applications
The Cypress CY62147G30-45ZSXI is a 4Mbit (256K x 16) MoBL® asynchronous SRAM with a 45 ns access time, operating from a 2.2 V supply. It uses a parallel interface and is housed in a 44-pin TSOP II package. The industrial temperature range (-40 to 85°C) suits outdoor telecom, factory automation, and motor-drive control boards where the SRAM holds look-up tables, packet buffers, or real-time parameter storage.
256K x 16 organisation — matches a 16-bit data bus
The 256K x 16 organisation matches a 16-bit data bus width without byte-lane muxing.
For dual-sourcing flexibility, the CY7C1041G30-10ZSXA offers the same 4Mbit density, 256K x 16 organisation, and 44-pin TSOP II package, but at a faster 10 ns access time — a drop-in upgrade if your bus timing demands it.
