AT24C02D-SSHM-T 2-Kbit serial EEPROM Memory IC 1 MHz 450 ns 8-SOIC
The AT24C02D-SSHM-T is a Microchip (formerly Atmel) 2-Kbit serial electrically erasable programmable read-only memory (EEPROM) organized as 256 words of 8 bits each, housed in an 8-lead SOIC (SN) surface-mount body and shipped on tape-and-reel carriers for automated assembly. As a member of the AT24C01D/02D family, it communicates over a standard I2C-compatible 2-wire serial bus and operates from a 1.7 V to 3.6 V supply across a -40 C to +85 C industrial temperature range, making it a compact non-volatile storage building block for microcontroller-based systems that must retain configuration data, calibration constants, and user preferences through power cycles.
What distinguishes the AT24C02D-SSHM-T is its combination of ultra-low power, high reliability, and hardware-level data protection wrapped in a standard SOIC-8 footprint. The device draws a maximum of 1 mA active current and only 0.8 uA standby current, supports 8-byte page write mode with partial page writes allowed, and provides a dedicated Write Protect (WP) pin that locks the entire memory array against unintended modification . Running at 400 kHz in Fast Mode from 1.7 V and scaling up to 1 MHz Fast Mode Plus from 2.5 V to 3.6 V, the EEPROM balances speed and voltage flexibility, while the lead-free, halide-free, RoHS-compliant SOIC-8 package keeps the solution small and environmentally compliant . Compared with the broader 24-series EEPROMs, the AT24C02D stands out for its tight 1.7 V to 3.6 V low-voltage optimization, making it especially suited to battery-powered and energy-harvesting nodes where every microamp of idle current matters.
Alternative EEPROM Solutions
1. 24LC02B-I/SN: Microchip 2-Kbit I2C EEPROM in SOIC-8 that extends the supply range to 2.5 V to 5.5 V, providing a similar 2 Kbit density with a wider voltage range for 5 V logic systems while keeping the same I2C signaling and family-level compatibility.
2. IS34C02B-2ZLI-TR: ISSI 2-Kbit I2C EEPROM in an 8-pin TSSOP package operating from 1.7 V to 3.6 V, serving as a functional alternative where the thinner TSSOP body is preferred over SOIC-8.
3. BR24L02FJ-WE2: ROHM 2-Kbit I2C EEPROM in an 8-pin SOP-J body with a 1.8 V to 5.5 V supply and 400 kHz bus speed, offered as a cross-vendor replacement for 5 V legacy systems that do not require 1 MHz operation.
4. AT24C02D-XHM-T: Microchip TSSOP-8 version of the same AT24C02D core with identical 1.7 V to 3.6 V operation and 1 MHz I2C interface, suitable when the narrower TSSOP footprint is required instead of SOIC-8.
