Key Features
Ultra-low current consumption
800µA (@4MHz CPU operation)
70µA (@500kHz CPU operation)
Low current consumption is ensured under all
operating modes: normal, suspend, stop
1V Flash ROM operation
High precision
Fewer parts required
Built-in PLL (Phase Locked Loop)
oscillation circuit
The internal Flash ROM can be read using only 1V.
Microcontroller operating voltage range: 1.1V to 3.6V
The internal PLL circuit generates the high-speed
4.096MHz clock by multiplying the 32.768kHz clock.
2 types of A/D converters built in for high precision
operation (16/24bit RISC oscillation type + 12bit
Successive approximation type)
Requires no resonator or oscillator for peripheral IC.
1V Flash ROM operation
High-speed 1 instruction/clock cycle 8bit
RISC CPU 'U8' core
Few current leakage at high temperature
2 types if A/D converters built in
A unique low-power method enables Flash memory reading at only 1V. In
addition, reducing the charge/discharge current through bit-line division
enables low power consumption equivalent to mask ROMs.
The 8bit RISC CPU utilizes parallel processing via a pipeline architecture
for high-speed, 1 instruction/clock cycle operation - reducing CPU
operating time significantly.
Original low-power processing prevents current leakage at high
temperatures, making OKI SEMICONDUCTOR MCUs compatible with
even industrial applications.
2 types of A/D converters are built in, a Successive Approximation type
requiring analog voltage input and an RC Oscillation type that counts the
number of oscillations caused by a resistive sensor (i.e. thermistor,
humidity) and external capacitor. Select the optimum sensor based on the
characteristics, measurement accuracy, and current consumption.
Applicable models: All models except low power microcontrollers with speech capability
Applicable models: Low power MCUs with built-in dot matrix LCD driver
