S80KS2564GACHI040

Active and preferred

The S80KS2564GACHI040 is a 256 Mb HYPERRAM self-refresh DRAM (PSRAM) with a 1.8 V (1.7 V to 2.0 V) HYPERBUS extended-IO x16 interface. It supports up to 200 MHz DDR operation for up to 800 MBps throughput and 35 ns max access time. In a 49-ball FBGA, the industrial grade (-40b0C to 85b0C) device includes partial-array refresh, hybrid sleep, and deep power-down modes for low standby power.
