The S70KL1283DPBHV020 is a 128 Mb HYPERRAM™ self-refresh DRAM (PSRAM) with an Octal xSPI DDR interface and 8-bit data bus plus RWDS and RESET#. It supports 3.0 V VCC/VCCQ and up to 166 MHz clock (DP speed grade), with tACC 35 ns. Self-managed refresh inserts extra initial latency when needed, and Hybrid Sleep and Deep Power Down reduce standby power for embedded memory expansion.
