S27KL0643DPBHV020

Active and preferred

S27KL0643DPBHV020 is a 64 Mb HYPERRAM™ self-refresh DRAM (PSRAM) for high-bandwidth, random-access expansion of embedded systems. It uses an octal xSPI interface with DDR transfers up to 200 MHz (400 MBps) and 35 ns maximum access time, with RWDS for latency indication and read/write strobe. The 3.0 V device runs from 2.7 V to 3.6 V across -40°C to +105°C, and supports deep power down at 15 µA (3.6 V, 105°C) in a 24-ball FBGA.
