FT24C512A
PIN DESCRIPTIONS
(A) SERIAL CLOCK (SCL)
The rising edge of this SCL input is to latch data into the EEPROM device while the falling edge of
this clock is to clock data out of the EEPROM device.
(B) DEVICE / CHIP SELECT ADDRESSES (A2, A1, A0)
These are the chip select input signals for the serial EEPROM devices. Typically, these signals are
hardwired to either V IH or V IL . If left unconnected, they are internally recognized as V IL .
(C) SERIAL DATA LINE (SDA)
SDA data line is a bi-directional signal for the serial devices. It is an open drain output signal and can
be wired-OR with other open-drain output devices.
(D) WRITE PROTECT (WP)
The FT24C512A device has a WP pin to protect the whole EEPROM array from programming.
Programming operations are allowed if WP pin is left un-connected or input to V IL . Conversely all
programming functions are disabled if WP pin is connected to V IH or V CC . Read operations is not
affected by the WP pin’s input level.
MEMORY ORGANIZATION
The FT24C512A devices have 512 pages respectively. Since each page has 128 bytes, random word
addressing to FT24C512A will require 16 bits data word addresses.
DEVICE OPERATION
(A) SERIAL CLOCK AND DATA TRANSITIONS
The SDA pin is typically pulled to high by an external resistor. Data is allowed to change only when
Serial clock SCL is at V IL . Any SDA signal transition may interpret as either a START or STOP
condition as described below.
(B) START CONDITION
With SCL ≥ V IH , a SDA transition from high to low is interpreted as a START condition. All valid
commands must begin with a START condition.
(C) STOP CONDITION
With SCL ≥ V IH , a SDA transition from low to high is interpreted as a STOP condition. All valid read
or write commands end with a STOP condition. The device goes into the STANDBY mode if it is after
a read command. A STOP condition after page or byte write command will trigger the chip into the
STANDBY mode after the self-timed internal programming finish (see Figure 3).
