24c04 512 X 8 BIT EEPROM

The Turbo 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 containing
16 bytes. This device offers significant advantages
in low power applications.
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.
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.
