The H8SX/1648 (H8SX/1642F, H8SX/1644F, H8SX/1648F) Group is a 32-bit CISC microcomputer with a maximum operating frequency of 50 MHz. It is upward pin-to-pin compatible with existing H8SX/1650, 1651, 1657 groups and supports greater ROM size from 256K to 1MB. The on-chip peripheral functions have been enhanced with 2 units of TPU and PPG, and 3 units of ADC. I2C also supports 5V input (with only channel 2and 3)
