Minimum instruction execution time can be changed from high speed (0.03125 s: @ 32 MHz operation with highspeed
on-chip oscillator clock) to ultra low-speed (30.5 s: @ 32.768 kHz operation with subsystem clock)
General-purpose register: 8 bits 32 registers (8 bits 8 registers 4 banks)
ROM: 24 to 256 KB, RAM: 2 to 16 KB, Data flash memory: 8 KB
On-chip high-speed on-chip oscillator clocks
Select from 32 MHz (TYP.), 24 MHz (TYP.), 16 MHz (TYP.), 8 MHz (TYP.), and 4 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 clock)
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)

Sound generator
8/10-bit resolution A/D converter (VDD = EVDD =2.7 to 5.5 V): 5 to 9 channels
Standby function: HALT, STOP, SNOOZE mode
Power supply voltage: VDD = 2.7 to 5.5 V
Operating ambient temperature: J grade products TA = 40 to +85C,
L grade products TA = 40 to +105C
Remark The functions mounted depend on the product. See 1.7 Outline of Functions.
