HT67F30/HT67F40/HT67F50/HT67F60 -- TinyPowerTM A/D Flash Type 8-Bit MCU with LCD & EEPROM
General Description
The HT67Fxx series of devices are Flash Memory A/D with LCD type 8-bit high performance RISC architecture microcontrollers, designed for applications that interface directly to analog signals and which require an LCD interface. 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 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 and dual comparator functions. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Communication with the outside world is catered for by including fully integrated SPI or I2C interface functions, two popular 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 with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.
A full choice of HXT, LXT, ERC, HIRC and LIRC oscillator functions are provided including a fully integrated system oscillator which requires no external components 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 minimise power consumption.
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.
