24LCS21  
1K 2.5V Dual Mode CMOS Serial EEPROM  
FEATURES  
DESCRIPTION  
• Completely implements DDC1 /DDC2  
interface for monitor identification  
• Hardware write-protect pin  
• Single supply with operation down to 2.5V  
• Low power CMOS technology  
The Microchip Technology Inc. 24LCS21 is a  
128 x 8-bit dual-mode Electrically Erasable PROM.  
This device is designed for use in applications requiring  
storage and serial transmission of configuration and  
control information. Two modes of operation have been  
implemented: Transmit Only Mode and Bi-Directional  
Mode. Upon power-up, the device will be in the  
Transmit Only Mode, sending a serial bit stream of the  
entire memory array contents, clocked by the VCLK  
pin. A valid high to low transition on the SCL pin will  
cause the device to enter the Bi-Directional Mode, with  
byte selectable read/write capability of the memory  
- 1 mA active current typical  
- 10 µA standby current typical at 5.5V

• Two wire serial interface bus, I C compatible  
(SCL)  
• Self-timed write cycle (including auto-erase)  
• Page-write buffer for up to 8 bytes  
• 100 kHz (2.5V) and 400 kHz (5V) compatibility  
(SCL)

array in standard I C protocol.  
• Factory programming (QTP) available  
• 10,000,000 erase/write cycles guaranteed  
• Data retention > 200 years  
• 8 pin PDIP and SOIC package  
• Available for extended temperature ranges  
- Commercial: 0°C to +70°C  
The 24LCS21 also enables the user to write-protect the  
entire memory contents using its write-protect pin. The  
24LCS21 is available in a standard 8-pin PDIP and  
SOIC package in both commercial and industrial  
temperature ranges.  
- Industrial:  
-40°C to +85°C
