Battery voltage detection function (BLD)
accurately detects remaining charge
Precise (±2%) battery voltage detection makes it possible to
manage operation and performance based on the remaining
battery level.
In addition, 16-step voltage detection is performed between
1.35V and 2.9V, with a voltage accuracy of ±2%.
Clock output reduces system costs
Both the low and high speed clocks can be output, eliminating
the need for an oscillator for the external peripheral IC,
reducing system costs.

Triple clock system facilitates low power design
Three different clocks can be selected for CPU operation: low-
speed (external) 32kHz crystal oscillation, medium-speed
(internal) 500kHz RC oscillation, and high-speed (internal)
4MHz PLL oscillation. The medium- and high-speed clocks can
be divided into 1/8ths in order to minimize current consumption.
In addition, the units are compatible with external 4MHz
precision oscillators for applications requiring greater accuracy.
