AT24C08C‑SSHM‑T I2C serial EEPROM IC 8Kbit I²C 1 MHz 550 ns 8-SOIC
AT24C08C‑SSHM‑T is an active‑production 8‑Kbit two‑wire I2C serial EEPROM manufactured by Microchip Technology, organized as 1024 × 8‑bit non‑volatile memory for storing small‑size configuration and calibration data. Packaged in 8‑pin narrow‑body SOIC surface‑mount housing and shipped on tape‑and‑reel, this low‑power CMOS memory chip supports a wide 1.7 V‑5.5 V supply voltage, 1 MHz maximum I2C clock speed, one‑million erase‑write endurance cycles and minimum 100‑year data retention, delivering stable read‑write performance across industrial temperature range from ‑40 °C to 85 °C for embedded consumer, industrial and IoT electronic systems.
Key Features
● 8‑Kbit non‑volatile storage capacity arranged as 1K × 8‑bit memory, with 16‑byte page write buffer to boost programming efficiency.
● Standard two‑wire I2C communication interface running up to 1 MHz clock frequency, which only consumes two microcontroller GPIO pins.
● Extra‑wide operating voltage of 1.7 V to 5.5 V, fully compatible with 1.8 V, 3.3 V and 5 V embedded power‑supply domains.
● Hardware write‑protect pin blocks accidental over‑writing of stored critical parameters to avoid data corruption.
● Ultra‑low power consumption with maximum 6 µA standby current and 3 mA active write‑mode current, well suited for battery‑powered devices.
FAQ
Q: How many AT24C08C devices can be placed on a single I2C bus?
A: Up to two chips, since only one hardware address pin is available for address selection.
Q: What PCB layout recommendations apply?
A: Add a decoupling ceramic capacitor close to the VCC pin, install external pull‑up resistors on SDA and SCL I2C signal lines, and keep serial‑communication traces short.
Alternative EEPROM Models
1. AT24C08C‑PU: DIP‑8 through‑hole version of this 8‑Kbit I2C EEPROM with identical electrical features, ideal for breadboard prototyping and manual soldering projects.
2. 24LC08B‑I/SN: Microchip cross‑compatible 8K‑bit serial EEPROM in SOIC‑8 package, serving as a fully drop‑in functional replacement for mass‑production circuit boards.
3. AT24C16C‑SSHM‑T: 16‑Kbit I2C EEPROM with the same SOIC‑8 footprint, an upgraded storage‑capacity option when larger memory space is required.
