This document is a preliminary ROM Library Function Guide for the PMA51xx / PMA71xx RF Transmitter IC, describing the features and characteristics of the product, including the embedded 8051 microcontroller, LF 125kHz ASK receiver, and FSK/ASK 315/434/868/915 MHz transmitter.
This document provides a detailed description of the ROM library functions available for the Infineon PMA51xx and PMA71xx RF transmitter integrated circuits. It includes function prototypes, input/output definitions, resource usage, and execution timing.
The guide is organized into sections covering revision history, general considerations, type definitions, and individual function descriptions such as MeasTemperature(), GetSupplyVoltage(), PowerDown(), and many others. Reference documents and cross‑references are listed at the end.
