BC45F0023

General Information

The device is a Flash Memory I/O type 8-bit high performance RISC architecture microcontroller with a fully integrated hopping code engine, specifically designed for wireless applications.

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.

With regard to internal timers, the device includes multiple extremely flexible Timer Modules, which provide timing, pulse generation and PWM generation functions. 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.

The device also includes fully integrated high and low speed 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 optimize microcontroller operation and minimize power consumption.

The hopping code engine specific to wireless applications is also fully integrated within the device, which is used to generate encryption and decryption functions, implementing secure wireless control. The inclusion of flexible I/O programming features, Time-Base functions along with many other features ensure that the device will be highly capable of providing a cost effective solution for a wide range of wireless applications, such as Automotive Remote Keyless Entry (RKE) systems, Automotive immobilizers, Community gates and garage door openers, Identity tokens with usage counters, Burglar alarm systems, Building access, etc.
