the HT48 & HT46 Series MCUs and the HT93LC46 EEPROM - HA0016E Writing and Reading to the HT24 EEPROM with the HT48 MCU Series - HA0018E Controlling the HT1621 LCD Controller with the HT48 MCU Series - HA0049E Read and Write Control of the HT1380 - HA0075E MCU Reset and Oscillator Circuits Application Note Features · Operating voltage: fSYS= 4MHz: 2.2V~5.5V fSYS= 8MHz: 3.3V~5.5V fSYS= 12MHz: 4.5V~5.5V · 7 bidirectional I/O lines and 1 input line · External interrupt input shared with an I/O line · One or two 8-bit programmable Timer/Event Coun- ters with overflow interrupt and 7-stage... The PWM function also allows the driving of external analog signals for applications such as motor driving while the PFD function provides a means of generating a fixed frequency reference. The usual Holtek microcontroller features of low power consumption, I/O flexibility, timer functions, oscil- lator options, power down and wake-up functions, watchdog timer and low voltage reset, combine to provide devices with a huge range of functional options while still maintaining cost effectiveness.
