S27KL0643DPBHI020

Active and preferred

S27KL0643DPBHI020 is a 64 Mb HYPERRAM™ self-refresh DRAM (PSRAM) with an Octal xSPI interface (8-bit DQ plus RWDS and RESET#). It is a 3.0 V-only device (VCC 2.7 V to 3.6 V), supports a 166 MHz max clock and DDR transfers, and offers burst throughput up to 400 MBps with configurable linear or wrapped bursts. It comes in a 24-ball FBGA package and is rated Industrial -40°C to +85°C.
