PMA7105

The SmartLEWIS™ MCU family comprises an ASK/FSK transmitter for the sub 1GHz ISM frequency bands with embedded 8051 microcontroller as base functionality. Additionally, exciting peripheral functions are integrated, building a fully flexible and pin-compatible product family. You can use the internal multi-channel 10-bit analog to digital converter with its flexible high gain settings as interface for a broad variety of analog sensors. The integrated LF-Receiver enables wireless wake-up in battery operated applications with ultra-long-lifetime or even contactless configuration of the device. A comprehensive software function library with high level commands in ROM allows easy and fast time to market development and helps reducing the user code size and as such expensive flash memory size. The software function library provides many powerful functions like AES-encryption and EEPROM emulation. The Smart LEWIS™ MCU includes an advanced power control system making this family ideal for battery operated applications where low current consumption is necessary. In combination with state-of-the-art development tools this makes RF easy to use for everyone allowing simple and fast time-to-market.
