Introduction
This document provides a detailed description of the
One-Time Programmable (OTP) function of the MMPF0100. It
provides the system requirements and instructions to program
the fuses for a selected power-up configuration. All examples
assume the customer is using silicon revision P1.1 or higher.
Freescale analog ICs are manufactured using the
SMARTMOS process, a combinational BiCMOS
manufacturing flow that integrates precision analog, power
functions and dense CMOS logic together on a single
cost-effective die.
