MEMORY EEPROM
256k BITS (32768 X 8) TWO-WIRE SERIAL
DESCRIPTION
FEATURES
The A24C256 provides 262144 bits of serial
electrically erasable and programmable read-only
memory (EEPROM), organized as 32768 words of
8 bits each.
Compatible with all I2C bidirectional data
transfer protocol
Memory array:
256k bits (32k bytes) of EEPROM
Page size: 64 bytes
The device is optimized for use in many industrial
and commercial applications where low-power and
low-voltage operation are essential.
Additional Write lockable page
Single supply voltage and high speed:
1
MHz (2.5V)
400 kHz (1.7V)
The A24C256 offers an additional page, named the
Identification Page (64 bytes). The Identification
Page can be used to store sensitive application
parameters which can be (later) permanently
locked in Read-only mode.
100 kHz (1.7V)
Random and sequential Read modes
Write:
Byte Write within 5 ms
Page Write within 5 ms
Partial Page Writes Allowed
Write Protect Pin for Hardware Data Protection
Schmitt Trigger, Filtered Inputs for Noise
Suppression
The A24C256 is available in SOP8, TSSOP8,
DFN8, DIP8 and CSP4 packages.
