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
· 6-level subroutine nesting
· Bit manipulation instruction
· Low voltage reset function
· 16-pin NSOP package
Peripheral Features
· 10 bidirectional I/O lines
· 4 channel 12-bit ADC
· 1 channel 8-bit PWM
· External interrupt input shared with an I/O line
· Two 8-bit programmable Timer/Event
Counter with overflow interrupt and prescaler
· Time-Base function
· Programmable Frequency Divider - PFD
· Embedded 3V DC/DC
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.
