The S80KS5123GABHA023 is a 512 Mb HYPERRAM™ self-refresh DRAM with an Octal xSPI (DDR) interface for high-bandwidth external RAM. It runs from 1.7 V to 2.0 V (1.8 V nominal), supports up to 200 MHz clock and 400 MBps throughput, and specifies 35 ns max access time. AEC-Q100 automotive grade options and deep power down to 30 µA (105°C) help reduce power in embedded memory expansion.
