PRODUCT INTRODUCTION

CMOS I²C 2-WIRE BUS

4K ELECTRICALLY ERASABLE PROGRAMMABLE ROM

512 X 8 BIT EEPROM

FEATURES :

• Power Supply Voltage

Single Vcc for Read and Programming

(Vcc = 2.7 V to 5.5 V)

• Low Power (Isb = 2µa @ 5.5 V)

DESCRIPTION:

TheTurbo IC 24C04 is a serial 4K EEPROM fabricated with

Turbo’s proprietary, high reliability, high performance CMOS

technology. It’s 4K of memory is organized as 512 x 8 bits.

The memory is configured as 32 pages with each page con-

taining 16 bytes. This device offers significant advantages

in low power applications.

• I²C Bus, 2-Wire Serial Interface

• Support Byte Write and Page Write (16 Bytes)

• Automatic Page write Operation (maximum 10 ms)

Internal Control Timer

Internal Data Latches for 16 Bytes

• High Reliability CMOSTechnology with EEPROM Cell

Endurance : 1,000,000 Cycles

The Turbo IC 24C04 uses the I²C addressing protocol and

2-wire serial interface which includes a bidirectional serial

data bus synchronized by a clock. It offers a flexible byte

write and a faster 16-byte page write.

Data Retention : 100Years

The Turbo IC 24C04 is assembled in either a 8-pin PDIP or

8-pin SOIC package. Pin #1 is not connected (NC). Pin #2

is the A1 device address input for the 24C04. Pin #3 is the

A2 device address input for the 24C04, such that a total of

four 24C04 devices can be connected on a single bus. Pin

#4 is the ground (Vss). Pin #5 is the serial data (SDA) pin

used for bidirectional transfer of data. Pin #6 is the serial

clock (SCL) input pin. Pin #7 is the write protect (WP) pin

used to protect hardware data. Pin #8 is the power supply

(Vcc) pin.

PIN DESCRIPTION

All data is serially transmitted in bytes (8 bits) on the SDA

bus. To access the Turbo IC 24C04 (slave) for a read or

write operation, the controller (master) issues a start condi-

tion by pulling SDA from high to low while SCL is high.The

master then issues the device address byte which consists

of 1010 (A2) (A1) (B8) (R/W).The most significant bits (1010)

are a device type code signifying an EEPROM device. A1

and A2 are the device address select bits which has to match

the A1 and A2 pin inputs on the 24C04 device.The B[8] bit

is the most significant bit of the memory address.The read/

write bit determines whether to do a read or write operation.

After each byte is transmitted, the receiver has to provide

an acknowledge by pulling the SDA bus low on the ninth

clock cycle. The acknowledge is a handshake signal to the

transmitter indicating a successful data transmission.

PIN DESCRIPTION

DEVICE ADDRESS (A1 & A2)

A1 and A2 are device address inputs that en-

ables a total of four 24C04 devices to connect

on a single bus. When the address input pin is

left unconnected, it is interpreted as zero.

SERIAL CLOCK (SCL)

SERIAL DATA (SDA)

WRITE PROTECT (WP)

The SCL input synchronizes the data on the SDA

bus. It is used in conjunction with SDA to define

the start and stop conditions. It is also used in

conjunction with SDA to transfer data to and from

the Turbo IC 24C04.

SDA is a bidirectional pin used to transfer data

in and out of the Turbo IC 24C04. The pin is an

open-drain output. A pullup resistor must be con-

nected from SDA to Vcc.

When the write protect input is connected toVcc,

the entire memory array is protected against write

operations. For normal write operations, the write

protect pin should be grounded. When the pin is

left unconnected, WP is interpreted as zero.
