CHAPTER 1 OUTLINE
1.1 Features
{ Minimum instruction execution time can be changed from high speed (0.03125
μ
s: @ 32 MHz operation with high-
speed on-chip oscillator) to ultra low-speed (30.5
μ
s: @ 32.768 kHz operation with subsystem clock)
{ General-purpose register: 8 bits × 32 registers (8 bits × 8 registers × 4 banks)
{ ROM: 16 to 512 KB, RAM: 2 to 32 KB, Data flash memory: −/4/8 KB
{ On-chip high-speed on-chip oscillator
• Select from 32 MHz (TYP.), 24 MHz (TYP.), 16 MHz (TYP.), 12 MHz (TYP.), 8 MHz (TYP.), 4 MHz (TYP.), and 1
MHz (TYP.)
{ On-chip single-power-supply flash memory (with prohibition of block erase/writing function)
{ Self-programming (with boot swap function/flash shield window function)
{ On-chip debug function
{ On-chip power-on-reset (POR) circuit and voltage detector (LVD)
{ On-chip watchdog timer (operable with the dedicated low-speed on-chip oscillator)
{ On-chip multiplier and divider/multiply-accumulator
• 16 bits × 16 bits = 32 bits (Unsigned or signed)
• 32 bits ÷ 32 bits = 32 bits (Unsigned)
• 16 bits × 16 bits + 32 bits = 32 bits (Unsigned or signed)
{ On-chip key interrupt function
{ On-chip clock output/buzzer output controller
{ On-chip BCD adjustment
{ I/O ports: 16 to 120 (N-ch open drain: 0 to 4)
{ Timer
• 16-bit timer: 8 to 16 channels
• Watchdog timer: 1 channel
• Real-time clock: 1 channel (Correction clock output)
• Interval timer: 1 channel
{ Serial interface
• CSI
• UART/UART (LIN-bus supported)
• I
2
C/Simplified I

C communication
{ Different potential interface: Can connect to a 2.5/3 V device when operating at 4.0 V to 5.5 V
{ 8/10-bit resolution A/D converter (V
DD = EVDD =1.6 to 5.5 V): 6 to 26 channels
{ Standby function: HALT, STOP, SNOOZE mode
{ Power supply voltage: V
DD = 1.6 to 5.5 V
{ Operating ambient temperature: T
A = −40 to +85°C
Remark The functions mounted depend on the product. See 1.6 Outline of Functions.
