High-Density 4 Mbit Parallel FAST SRAM with Industrial Qualification and Reliable Performance CY7C1041GN30-10ZSXI is a 4-Mbit (256K × 16) fast asynchronous CMOS SRAM for 2.2 V to 3.6 V industrial systems (-40°C to +85°C). It supports 10 ns address access (tAA) and byte writes/reads via BLE/BHE. TTL-compatible I/O is specified with VOH ≥2.4 V and VOL ≤0.4 V at VCC 2.7 V to 3.6 V. Currents include ICC 45 mA max at fMAX and ISB2 8 mA max (CMOS standby). It comes in a Pb-free 44-pin TSOP II package.
