Product Brief
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 SmartLEWIS™ 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.
Key Benefits
Flexibility of design: only one device covering the sub 1GHz ISM frequency bands
and three output power levels
High level of integration with only a few external components lowers system cost
and increases reliability
ADC with flexible high gain settings and dierential or single ended inputs support a
broad variety of analog sensors
125kHz LF Receiver with wireless wakeup or contactless configuration of the device
Extend battery life due to advanced power control system
Easy-to-use tools enable to shorten development time
