HT67F4892

General Information

The HT67F4892 is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller, designed especially for applications that interface directly to analog signals, such as those from sensors. For memory features, the Flash Memory offers users the convenience of multi-programming features.

Offering users the convenience of Flash Memory multi-programming features, this device also includes 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. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Easy communication with the outside world is provided by including fully integrated SPI, I²C functions, 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 external, internal and high and low oscillators functions are provided including two fully integrated system oscillators which require no external components for their 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 UART module is contained in the device. It can support the applications such as data communication networks between microcontrollers, affordable data links between PCs and peripheral devices, portable and battery operated device communication, etc.

The inclusion of both LCD and LED driver functions allows for easy and affordable solutions in applications that require interface to these display types. In addition, the inclusion of flexible I/O programming features, Time-Base functions along with many other features ensure that only a minimum of external components is required for application implementation, resulting in reduced component costs and reductions in circuit board areas.
