MCHPAT24C02D-STUM-T
Overview
The AT24C02D-STUM-T is a 2Kbit industrial-grade serial EEPROM from Microchip, organized as 256 bytes of 8 bits each. It operates over a wide voltage range of 1.7V to 3.6V and supports the I2C protocol at clock frequencies up to 1MHz. This memory IC is housed in a compact 5-lead SOT-23 (TSOT) package, making it suitable for space-constrained designs requiring non-volatile parameter storage.
Why Choose This Part
This device offers extremely low power consumption, with a standby current of only 0.8uA and a read current of 0.3mA at 1.8V. Its high-speed 1MHz I2C compatibility allows for fast data retrieval, while the SOT-23-5 package provides a minimal PCB footprint compared to standard SOIC options.
Applications
Key Specifications
Getting Started
To interface with this EEPROM, connect the SCL and SDA lines to a microcontroller's I2C master port with appropriate pull-up resistors. Ensure the VDD supply remains within the 1.7V to 3.6V range and utilize standard I2C libraries to perform byte or page writes. Review the datasheet for timing requirements specifically regarding the 4.5us access time and internal write cycles.
