registers and select whether the I-Port or one of the internal non-

volatile registers is output to the Y-port. The FM3540/50/60 is

General Description

The FM3540/50/60 multiplexes the I-port input signals with two

internalnon-volatileregistersthatcanbeloadedthroughtheserial

port. The multiplexer is selected via the serial port and defaults to

the I-Port upon power-up. Pull-up resistors are provided on the

input port to accommodate connections to open drain outputs and

to eliminate the need for external resistors. The device supports

a choice of either 2.5V output or Open Drain Outputs for easy

interface to devices with different VDD Levels.

fabricated with an advanced CMOS technology to achieve high

density and low power.

Features

I Extended Operating Voltage Range 3.0V-5.5V

I IIC Compatible Slave Interface.

I ESD performance: Human body model > 2000V

I Choice of 2.5V outputs or Open-Drain Outputs

The serial port is an IIC compatible slave only interface and

supportsboth100kbitsand400kbitsmodesofoperation. Theport

is used to read the I-Port, Write Data to the internal non-volatile
