General Description

The HT66FXX series of devices are Flash Memory A/D

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 EEPROM memory for storage of non-volatile

data such as serial numbers, calibration data etc.

with excellent noise immunity and ESD protection en-

sure that reliable operation is maintained in hostile elec-

trical environments.

A full choice of HXT, LXT, ERC, HIRC and LIRC oscilla-

tor functions are provided including a fully integrated

system oscillator which requires no external compo-

nents for its implementation. The ability to operate and

switch dynamically between a range of operating

modes using different clock sources gives users the

ability to optimise microcontroller operation and mini-

mise power consumption.

Analog features include a multi-channel 12-bit A/D con-

verter and dual comparator functions. Multiple and ex-

tremely flexible Timer Modules provide timing, pulse

generation and PWM generation functions. Communi-

cation with the outside world is catered for by including

fully integrated SPI or I²C interface functions, two popu-

lar interfaces which provide designers with a means of

easy communication with external peripheral hardware.

Protective features such as an internal Watchdog Timer,

Low Voltage Reset and Low Voltage Detector coupled

The inclusion of flexible I/O programming features,

Time-Base functions along with many other features en-

sure that the devices will find excellent use in applica-

tions such as electronic metering, environmental

monitoring, handheld instruments, household appli-

ances, electronically controlled tools, motor driving in

addition to many others.
