FM24C04U/05U – 4K-Bit Standard 2-Wire Bus

Interface Serial EEPROM

General Description

Features

The FM24C04U/05U devices are 4096 bits of CMOS non-volatile

electrically erasable memory. These devices conform to all speci-

fications in the Standard IIC 2-wire protocol. They are designed to

minimize device pin count and simplify PC board layout require-

ments.

I Extended operating voltage 2.7V – 5.5V

I 400 KHz clock frequency (F) at 2.7V - 5.5V

I 200µA active current typical

10µA standby current typical

1µA standby current typical (L)

0.1µA standby current typical (LZ)

The upper half (upper 2Kbit) of the memory of the FM24C05U can

be write protected by connecting the WP pin to V_CC. This section of

I IIC compatible interface

memory then becomes unalterable unless WP is switched to V_SS

– Provides bi-directional data transfer protocol

This communications protocol uses CLOCK (SCL) and DATA

I/O (SDA) lines to synchronously clock data between the master

(forexampleamicroprocessor)andtheslaveEEPROMdevice(s).

The Standard IIC protocol allows for a maximum of 16K of

EEPROM memory which is supported by the Fairchild family in

2K, 4K, 8K, and 16K devices, allowing the user to configure the

memory as the application requires with any combination of

EEPROMs. In order to implement higher EEPROM memory

densities on the IIC bus, the Extended IIC protocol must be used.

(RefertotheFM24C32orFM24C65datasheetsformoreinforma-

tion.)

I Sixteen byte page write mode

– Minimizes total write time per byte

I Self timed write cycle

Typical write cycle time of 6ms

I Hardware Write Protect for upper half (FM24C05U only)

I Endurance: 1,000,000 data changes

I Data retention greater than 40 years

I Packages available: 8-pin DIP, 8-pin SO, and 8-pin TSSOP

I Available in three temperature ranges

- Commercial: 0° to +70°C

Fairchild EEPROMs are designed and tested for applications requir-

ing high endurance, high reliability and low power consumption.

- Extended (E): -40° to +85C

- Automotive (V): -40° to +125°C
