DESCRIPTION
The MB89860/850 series has been developed as a general-purpose version of the F
2
MC*-8L family consisting
of proprietary 8-bit, single-chip, microcontrollers.
In addition to the F
2
MC-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.
*: F

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)
Instruction set optimized for controllers

DIFFERENCES AMONG PRODUCTS
1. Memory Size
Before evaluating using the OTPROM (one-time PROM) products (also used for evaluation), verify its differences
from the product that will actually be used.
Take particular care on the following point:
· The stack area, etc., is set at the upper limit of the RAM.
2. Current Consumption
When operated at low speed, the product with an OTPROM or an EPROM will consume more current than the
product with a mask ROM.
However, the current consumption in sleep/stop modes is the same.
3. Mask Options
In the MB89P857/W857/P867/W867/T855, no option can be set.
Before using options check section "
s
Mask Options."
Take particular care on the following point:
· A pull-up resistor can be set for P00 to P07, P10 to P17 and P20 to P27 only at single-chip mode.
