256 Kb I2C CMOS Serial
EEPROM in WLCSP Package
WLCSP6
C6PTG SUFFIX
CASE 567ZZ
NV24C256C6PTG
Description
The NV24C256C6PTG is a 256 Kb Serial CMOS EEPROM,
internally organized as 32768 words of 8 bits each.
They feature a 64-byte page write buffer and support both the
Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) I C
protocol.
The Write Protect input allows hardware protection for the memory
array. The A2 input allows two NV24C256C6PTG devices to be
connected to the same bus.
