HT66F002/HT66F0025/HT66F003/HT66F004
Cost-Effective A/D Flash MCU with EEPROM
HT66F002/HT66F0025/HT66F003/HT66F004
Cost-Effective A/D Flash MCU with EEPROM
General Description
The devices are Flash Memory type 8-bit high performance RISC architecture microcontrollers.
Offering users the convenience of Flash Memory multi-programming features, these devices also
include a wide range of functions and features. Other memory includes an area of RAM Data
Memory as well as an area of true EEPROM memory for storage of non-volatile data such as serial
numbers, calibration data etc.
Analog features include a multi-channel 12-bit A/D converter function. Multiple and extremely
flexible Timer Modules provide timing, pulse generation, capture input, compare match output,
single pulse output and PWM generation functions. Protective features such as an internal Watchdog
Timer and Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure
that reliable operation is maintained in hostile electrical environments.
A full choice of HIRC and LIRC oscillator functions are provided including a fully integrated
system oscillator which requires no external components for its implementation.
The inclusion of flexible I/O programming features, Time-Base functions along with many other
features ensure that the devices will find excellent use in applications such as electronic metering,
environmental monitoring, handheld instruments, household appliances, electronically controlled
tools, motor driving in addition to many others.
