General Description
SA24C512 is a 512-Kbit CMOS nonvolatile serial EEPROM organized as 64K x
8 bit memory. This device conforms to
Extended IIC 2-wire protocol that allows
accessing of memory in excess of 16Kbit
on an IIC bus. This serial communication
protocol uses a Clock signal (SCL) and a
Data signal (SDA) to synchronously clock
data between a master (e.g. a
microcontroller) and a slave (EEPROM).
SA24C512 offers hardware write protection
whereby the entire memory array can be
write protected by pulling WP pin to logic
HIGH. The entire memory then becomes
unalterable until the WP pin is switched to
logic LOW. The device also features
programmable write protect with options of
full, half, or a quadrant of the array.
The “LZ” version of the SA24C512 offers
very low standby current, making it suitable
for low-power applications. SA24C512 is
designed to minimize pin count and
simplify PC board layout requirements.
This device is offered in SO, DIP and
Leadless MLF packages.
Saifun’s EEPROMs are designed and
tested for applications requiring high
endurance, high reliability and low power
consumption.

WP Write Protect Has an internal "weak" pull down so that when
left unconnected assumes logic LOW.
When LOW, Write is allowed to the memory
array.
When HIGH, Write is not allowed to the memory
array as defined in Write Protect (WP), page 14.
VCC Device Power Input
2.7 V to 3.6 V
Note:
No A2 pin (Pin 3) is provided. Treated as No Connect. Internal address
comparison assumes this pin to be 0 and hence the command code should
have corresponding bit set to 0.
