16 bits

•Clock multiplier circuit (⋅1/2, ⋅2, ⋅3, and ⋅4) to protect your surrounding environment Reducing the radiation interference

High-speed operation using the inexpensive low-speed oscillator (external 4 MHz; internal 16 MHz max.)

•Power management capabilities to contribute to the conservation of energy: STOP, SLEEP, subclock, hardware standby

•AL 2 layers 0.5 µm (reducing the chip footprint)

•Low-voltage, low-power voltage dissipation

Supporting large memory (up to 256 Kbytes for ROM; up to 10 Kbytes for RAM)

•Power dissipation reduced by 60 % as compared to the earlier product (5 V compatible product)
