Serial communication
interface
Two serial communication interface channels on chip
•
SCI3-1: 8-bit synchronous/asynchronous serial interface
Incorporates multiprocessor communication function
•
SCI3-2: 8-bit synchronous/asynchronous serial interface
Incorporates multiprocessor communication function
14-bit PWM
Pulse-division PWM output for reduced ripple
•
Can be used as a 14-bit D/A converter by connecting to an external
low-pass filter.
A/D converter
Successive approximations using a resistance ladder
•
8-channel analog input pins
•
Conversion time: 31/ø or 62/ø per channel
LCD controller/driver
LCD controller/driver equipped with a maximum of 32 segment pins and
four common pins
•
Choice of four duty cycles (static, 1/2, 1/3, or 1/4)
•
Segment pins can be switched to general-purpose port function in 8-
bit units
