■ DESCRIPTION

The MB89810A series is a line of single-chip microcontrollers based on the F2MC*-8L CPU core which can operate at low voltage but at high speed. The microcontrollers contain peripheral function such as timer, serial interface, a UART, and an external interrupt. The MB89810A series is applicable to a wide range of applications from welfare products to industrial equipment, including portable devices.

■ FEATURES

High speed processing at low voltage

Minimum execution time: 0.8 µs/3.0 V, 1.33 µs/2.2 V

• F2MC-8L family CPU core

Instruction set optimized for controllers

Multiplication and division instructions

16-bit arithmetic operations

Test and branch instructions

Bit manipulation instructions, etc.

• Four types of timers

8-bit PWM timer: 2 channels (also serve as reload timers)

16-bit timer/counter

21-bit time-base timer

• Two serial interface

8-bit synchronous serial (Switchable transfer direction allows communication with various equipment.)

UART (5-, 7-, or 8-bit transfer capable)

• External interrupt: 8 channels

Eight channels are independent and capable of wake-up from low-power consumption modes (with an edge detection function).

• Low-power consumption modes

Stop mode (Oscillation stops to minimize the current consumption)

Sleep mode (The CPU stops to reduce the current consumption to approx. 1/3 of normal)
