Migrating from the RX210 Group to the RX230 Group or RX231 Group

PublishTime：2020-12-16

This application note describes guidelines for migrating microcontroller code from the RX210 Group to the RX230 Group or RX231 Group, which are highly compatible with the RX210 Group.With the exception of some dedicated pins, the pin assignments of the RX230 Group and RX231 Group are identical to those of the RX210 Group. The RX230 Group and RX231 Group have the same functions (backward compatible) as the RX210 Group as well as new functions that are not included in RX210 Group microcontrollers.The specifications of the RX210 Group microcontrollers are compared below with those of RX230 Group and RX231 Group microcontrollers with the same package pin counts, and information is provided to enable users to confirm points of difference.100-pin, 64-pin, and 48-pin packages The RX231 Group is available in three versions: A, B, and C.The differences between these three versions are summarized below.
