Specification
Large on-chip memory
• H8/3802: 16-kbyte ROM, 1-kbyte RAM
• H8/3801: 12-kbyte ROM, 512 byte RAM
• H8/3800: 8-kbyte ROM, 512 byte RAM
50 pins
• 39 I/O pins
• 5 input pins
• 6 output pins
Three on-chip timers
• Timer A: 8-bit timer
Count-up timer with selection of eight internal clock signals divided
from the system clock (ø)* and four clock signals divided from the
watch clock (ø_w)*
• Asynchronous event counter: 16-bit timer
 Count-up timer able to count asynchronous external events
independently of the MCU's internal clocks
Asynchronous external events can be counted (both rising and falling
edge detection possible)
• Timer F: 16-bit timer
 Can be used as two independent 8-bit timers
 Count-up by an event input from the four internal clocks
 Provision for toggle output by means of compare-match function
• SCI3: 8-bit synchronous/asynchronous serial interface
Incorporates multiprocessor communication function
Pulse-division PWM output for reduced ripple
• Can be used as a 10-bit D/A converter by connecting to an external
low-pass filter.
Successive approximations using a resistance ladder
• 4-channel analog input pins
• Conversion time: 31/ø or 62/ø per channel
