■ DESCRIPTION

The MB89860/850 series has been developed as a general-purpose version of the F2MC*-8L family consisting 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 a variety of peripheral functions such as a timer unit, PWM timers, a UART, a serial interface, a 10-bit A/D converter, and an external interrupt.
The MB89860/850 series is applicable to a wide range of applications from welfare products to industrial equipment, including portable devices.

■ FEATURES

• Various package options
QFP package (80 pins): MB89860
SDIP package (64 pins): MB89850
• High-speed processing at low voltage
Minimum execution time: 0.4 µs/3.5 V, 0.8 µs/2.7 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.
• 8-bit PWM timers: 2 channels
Also usable as a reload timer
• UART
Full-duplex double buffer
Synchronous and asynchronous data transfer
• 8-bit serial I/O
Switchable transfer direction allows communication with various equipment.
• 10-bit A/D converter
Conversion time: 13.2 µs
Activation by an external input or a timer unit capable
• External interrupt: 4 channels
Four 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.)
• Bus interface functions
Including hold and ready functions
• Timer unit
Outputs non-overlap three-phase waveforms to control an AC inverter motor.
Also usable as a PWM timer (4 channels)
