Enhanced A/D Flash Type MCU 8-Bit MCU with EEPROM

Holtek Semiconductor 

HT66F20/HT66F30/HT66F40/HT66F50/HT66F60

HT66FU30/HT66FU40/HT66FU50/HT66FU60

Note:

I/T: Input type; O/T: Output type

OP: Optional by configuration option (CO) or register option

PWR: Power; CO: Configuration option; ST: Schmitt Trigger input

CMOS: CMOS output; NMOS: NMOS output

SCOM: Software controlled LCD COM; AN: Analog input pin

HXT: High frequency crystal oscillator

LXT: Low frequency crystal oscillator

*: VDD is the device power supply while AVDD is the ADC power supply. The AVDD pin is bonded together

internally with VDD.

**: VSS is the device ground pin while AVSS is the ADC ground pin. The AVSS pin is bonded together

internally with VSS.

As the Pin Description Summary table applies to the package type with the most pins, not all of the above listed

pins may be present on package types with smaller numbers of pins.
