CYStek Product Specification

2-Wire Serial EEPROMs 1K/2K/4K/8K/16K

CTK24BC01-16Q8

Description

The CTK24BC family provides 1K, 2K, 4K, 8K and 16K of serial electrically erasable and programmable

read-only memory (EEPROM). The wide Vdd range allows for low-voltage operation down to 1.8V. The

device, fabricated using traditional CMOS EEPROM technology, is optimized for many industrial and

commercial applications where low-voltage and low-power operation is essential. The device is accessed

via a 2-wire serial interface.

Features

• Internally organized as 128×8(1K), 256×8(2K)

• 100kHz(1.8V)& 400kHz(5V) compatibility

512×8(4K), 1024×8(8K), 2048×8(16K)

• Bi-directional data transfer protocol

• Low-voltage and standard-voltage operation :

• Self-timed write cycle (5ms max)

1.8~5.5V

• Write protect pin for hardware data protection

• 2-wire serial interface bus

• 8-byte page (1K, 2K) and 16-byte page (4K, 8K, 16K)

• Date retention : 100 years

write modes

• High endurance : 1,000,000 write cycles

• Allows for partial page write
