■ DESCRIPTION

The MB89670/A series has been developed as a line of proprietary 8-bit, single-chip microcontrollers.

In addition to the F2MC*-8L CPU core which can operate at low voltage but at high speed, the microcontrollers contain pheripheral functions such as timers, a serial interface, an A/D converter, a UART, an up/down counter, and an external interrupt.

The MB89670/A series is applicable to a wide range of applications from welfare products to industrial equipment, including portable devices.

■ FEATURES

• 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.

• High-speed processing at low voltage

• Minimum execution time: 0.4 µs/3.5 V, 0.8 µs/2.7 V, 2.0 µs/2.2 V

• I/O ports: max. 69 channels

• Timers: 9 channels (MB89670A: 12 channels)

8-bit PWM timer: 3 channels (MB89670A: 6 channels) (also usable as a reload timer)

16-bit timer/counter

21-bit time-base timer

8/16-bit timer (8 bits × 2 channels or 16 bits)

8/16-bit up/down counter timer (8 bits × 2 channels or 16 bits)

• Two serial interfaces

8-bit synchronized serial: 1 channel (Switchable transfer direction allows communication with various equipment.)

UART: 1 channel (with full-duplex double buffer)

• External interrupts: 8 channels

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

• Buzzer output

• 10-bit A/D converter

8-channel input

• 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.)

• Bus interface function

Including hold and ready functions
