Description
Three serial communication interface channels on chip
• SCI1: Synchronous serial interface
Choice of 8-bit or 16-bit transfer data
• 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
• 12-channel analog input pins
• Conversion time: 31/ø or 62/ø per channel
LCD
controller/driver
LCD controller/driver equipped with a maximum of 40 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
LCD drive power Step-up constant-voltage power supply allows LCD display.(H8/3887 Series only)
