The HT67F488/HT67F489 series of devices are Flash Memory A/D type 8-bit high performance RISC architecture microcontrollers, designed especially for applications that interface directly to analog signals, such as those from sensors. Offering users the convenience of Flash Memory multiprogramming 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 (only for HT67F489) for storage of non-volatile data such as serial numbers, calibration data etc.
