The H8SX/1645 Group enhances the analog functions (ADC and DAC) of theexisting H8SX/1648 Group. Peripheral functions have been further enhanced witha 10-bit ADC (3units) which achieves a conversion speed of 1 μs (2.7 times theconventional speed) and an on-chip 10-bit DAC (8-bit for H8SX/1648). TheH8SX/1645 Group is also pin-to-pin compatible with the H8SX/1648 Group.
