Professional microcontroller solutions for your applications
Overview
The device is a Flash Memory type 8-bit high performance RISC architecture microcontroller.
For memory features, the Flash Memory offers users the convenience of multi-programming 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 and a comparator function. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM output 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 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 and internal low and high oscillator functions are provided including 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 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 electronic metering, environmental monitoring, handheld instruments, household appliances, electronically controlled tools, motor driving in addition to many others.

e-Socket
(Programming Hardware)The e-Socket is a socket which is used together with e-WriterPro. MCUs with the same package types can use the same e-Socket for programming. It is not necessary to purchase individual programming adaptors for different MCUs. The e-Socket is designed with a programming counter which enables the e-WriterPro to remind users when to replace the e-Socket with a new one after a certain amount of times. This function is provided to maintain high programming quality.
e-WriterPro2
(Programming Hardware)The e-WriterPro2 is an upgraded version programmer of the e-WriterPro, which is fully compatible with the previous version, and it can be used not only as a programming tool for all of Holtek’s OTP and Flash devices during development stage but can also be used for small to medium volume production purposes.
