BX68R004
Cost-Effective I/O OTP MCU
General Information
This device is an OTP type 8-bit high performance RISC architecture microcontroller, designed for cost-effective product applications.
The device includes two extremely flexible Timer/Event Counters providing functions for timing, event counting and pulse width measurement functions. Protective features such as an internal Watchdog Timer and Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments.
A full choice of internal high and low speed oscillators are provided and the two fully integrated system oscillators 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 optimize microcontroller operation and minimize power consumption.
The inclusion of flexible I/O programming features, Time-Base function 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.
