AT24C02C-MAHM-T EEPROM Memory IC 2Kbit I²C 1 MHz 550 ns 8-UDFN (2x3)
The AT24C02C-MAHM-T is Microchip's 2Kbit serial EEPROM with I2C two-wire interface, housed in ultra-compact UDFN-8 package. It is organized as 256 x 8-bit memory words, supports 1.7V to 5.5V wide supply voltage, and provides 1MHz high-speed I2C communication. This nonvolatile memory delivers 1,000,000 erase/write cycles and 100-year data retention, operates from -40°C to 85°C industrial temperature range, and features built-in write protection for reliable parameter storage in space-constrained embedded systems.
Key Features & Applications
● 2Kbit memory capacity organized into 256 bytes with byte and page write operations, 8-byte page buffer.
● I2C two-wire serial interface supporting up to 1MHz clock frequency and three address pins for multi-device bus stacking.
● Wide operating voltage from 1.7V to 5.5V, compatible with both 3.3V and 5V logic systems.
● High endurance of 1,000,000 erase/write cycles and 100-year nonvolatile data retention at rated temperature.
● Hardware write-protection pin to lock the entire memory array and prevent accidental data overwriting.
This 2Kbit EEPROM is widely used to store configuration parameters, calibration data, device ID and user logs for smart sensors, wearable devices, IoT wireless modules, home appliances, handheld measurement instruments, industrial control boards and consumer embedded electronics. It offers small-footprint nonvolatile memory for storing small-volume persistent data that needs to remain after power removal.
FAQ
Q: What is the maximum page write size of AT24C02C-MAHM-T?
A: It supports 8-byte page write. Add pull-up resistors on SDA and SCL lines, and respect the write cycle waiting time to avoid incomplete data programming.
