PMA5105

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 MIPS when using the 12 MHz RC HF oscillator.
