General Description
The 1.5V Battery MCUs are a series of 8-bit high perfor-
mance, RISC architecture microcontrollers specifically
designed for a wide range of applications. The usual
Holtek microcontroller features of a 3V DC/DC con-
verter low power consumption, I/O flexibility, timer func-
tions, oscillator options, power down and wake-up
functions, watchdog timer and low voltage reset, com-
bine to provide devices with a huge range of functional
options while still maintaining a high level of cost effec-
tiveness. The fully integrated 3V DC/DC converter,
which transforms 1.5V to 3V, provides the MCUs a sta-
ble 3V power supply, opens up a huge range of new
1.5V application possibilities for these devices, some of
which may include, consumer products, household ap-
pliances subsystem controllers, etc.
