The MX25LW5124G Read-While-Write Flash has been chosen by Renesas for its RH850/D1M1A automotive instrument cluster MCU to provide Over-The-Air (OTA) updates. Macronix’s Read-While-Write (RWW) Flash offers an ideal solution for OTA update applications.
To have the latest features and update to meet emerging safety standards, automotive manufacturers are turning to OTA updates. OTA operation means the updated data and code can occur in mid execution. In the past, to implement an Over-The-Air update, a system would execute a Simultaneous Read-While-Write (RWW) operation in two separate Flash devices. The MX25LW51245G RWW Flash provides multiple bank architecture with simultaneous Read-While-Write capability that allows read access from one memory bank while writing to another memory bank.
