EEPROM 8 Kbit I2C Serial SOT-23 5-Pin MICROCHIP

EEPROM, 8 Kbit, 4 BLK 256 x 8bit, Serial I²C (2-Wire), 400kHz, SOT-23, 5 Pins

This MICROCHIP 24AA08T-I/OT is an 8-Kbit I²C serial EEPROM, organized as four blocks of 256 x 8-bit memory. The two-wire serial interface is I²C compatible, and the low-voltage design allows operation down to 1.7V, making it ideal for battery-powered applications.

Key Features

• Two-wire serial interface, I²C compatible.
• Schmitt trigger inputs for noise suppression.
• Output slope control to eliminate ground bounce.
• Self-timed erase/write cycle with 16-byte page write buffer.
• Hardware write-protect for added security.
• ESD protection > 4,000V.
• Data retention > 200 years.
• More than 1 million erase/write cycles.
• Industrial operating temperature range from -40°C to +85°C.

Performance

• Supply voltage range: 1.7V to 5.5V.
• Clock frequency max: 100kHz at 1.7V ≤ VCC < 2.5V; 400kHz at VCC ≥ 2.5V.
• Operating current: 1mA max (at VCC = 5.5V, SCL = 400kHz, TA = -40°C to +85°C).
• Standby current: 1µA max (at SDA = SCL = VCC, WP = VSS, TA = -40°C to +85°C).
• Write cycle time (byte or page): 5ms max (TA = -40°C to +85°C, VCC = +1.7V to +5.5V).
