The H8SX/1658R (H8SX/1653RF, H8SX/1654RF, H8SX/1658RF) Group is a 32-bit CISC microcomputer with a maximum operating frequency of 50 MHz. It is upward pin-to-pin compatible with H8SX/1653 group and supports ROM size from 384K to 1MB. The on-chip peripheral functions have been enhanced with 2 units of TPU, PPG and ADC. And On-chip EXDMAC allows for parallel data transfer on the internal bus and external bus.
