The device is a Flash Memory A/D type 8-bit high performance RISC architecture microcontroller which includes a multi-channel 24-bit Delta Sigma A/D converter designed for applications that interface directly to analog signals and which require a low noise and high accuracy analog to digital converter. 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 with 24-bit Delta Sigma A/D converter and programmable gain amplifier (PGA) functions. An extremely flexible Timer Module provides timing, pulse generation and PWM generation functions. Communication with the outside world is catered for by including fully integrated SPI, I2C and UART interface functions, three popular interfaces which provide designers with a means of easy communication with external peripheral ardware. In addition, an internal LDO function provides various power options for use by both internal functions and external devices. 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 internal low and high speed oscillator functions is 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 device will find excellent use in applications such as weight scales, electronic metering, environmental monitoring, handheld instruments, household appliances, electronically controlled tools, motor driving in addition to many others.
