Overview
The SmartLEWIS™ MCU family comprises an ASK/FSK multiband transmitter for the sub 1GHz ISM frequency
bands with an embedded 8051 microcontroller as base functionality. Additionally, the highly integrated single chip
family has internal sensors and optional peripheral functions like an analog to digital converter (ADC) and a
LF Receiver on chip. The operating voltage range of 1.9 to 3.6 V, the high efficiency Power Amplifier and an
advanced power control system make the PMA51xx family ideal for battery operated applications where low
current consumption is necessary. The pin-compatible product family requires only a few external components
and is the basis for flexible wireless control transmitter platforms enabling applications for different frequency
bands, output power levels and feature sets based on only one design - just through different mounting options.
The multiband ASK/FSK transmitter for 315/434/868/915 MHz frequency bands contains a fully integrated VCO,
a PLL synthesizer, an ASK/FSK modulator and a high efficiency Power Amplifier with selectable output power.
Fine tuning of the center frequency can be done by an on-chip capacitor bank.
The integrated microcontroller is instruction set compatible to the standard 8051 processor. It can be clocked with
an internal 12 MHz RC HF or an external oscillator. 6 clock cycles are needed for the execution of one instruction.
This results in 2 MIPS¹⁾ when using the 12 MHz RC HF oscillator. The microcontroller is equipped with various
peripherals like a hardware Manchester/BiPhase Encoder/Decoder and a CRC Generator/Checker. To store the
microcontroller application program code, a 6 kbyte on-chip FLASH memory is integrated. This FLASH memory
is also used for saving the unique ID-number of the chip. A comprehensive software function library with high level
commands in ROM allows easy and fast time to market development. The library provides many powerful
functions like AES-encryption and EEPROM emulation, what helps to reduce the user code size.
Additional peripherals are an integrated temperature sensor and a low battery voltage sensor. Measurements via
these internal sensors and reading signals from analog inputs (e.g. from an external analog sensor) are performed
under software control.
Depending on the product variant, PMA51xx offers an embedded multi-channel 10-bit analog to digital converter
with flexible high-gain settings as interface for a broad variety of analog sensors and an integrated
125 kHz LF Receiver. The LF Receiver enables wireless wake-up in battery operated applications with ultra-long-
lifetime or even contactless configuration of the device.
