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.
