CAT24C08YI-GT3JN onsemi 8-Kb I2C Serial CMOS EEPROM 8-TSSOP
The CAT24C08YI-GT3JN is an 8-Kb serial CMOS EEPROM from onsemi's CAT24Cxx family, housed in an 8-TSSOP (4.40 mm body) and positioned for general-purpose non-volatile parameter storage across consumer, industrial, and automotive-adjacent systems. Internally organized as 64 pages of 16 bytes each (1K x 8 bits, total 1024 bytes), the device supports both Standard (100 kHz) and Fast (400 kHz) I2C protocol, with external address pins allowing up to two CAT24C08 devices on the same bus for 16-Kb aggregate capacity.
Deployment spans board-ID and serial-number storage (DRAM modules, graphics cards, notebook/desktop BIOS peripheral config), calibration and trim data (health meters, industrial sensors, cable modems, set-top boxes), user-preference and state retention (smartphones, cordless phones, vending machines, wireless LAN APs), and parameter shadowing in alarm systems, automotive comfort ECUs, CRT/LCD monitor EDID adjuncts, and DVD/STB platforms.
Alternative I2C EEPROM Models
● 24LC08BT-I/OT: Microchip 8-Kb I2C EEPROM, 1.7–5.5 V, 400 kHz, SOT-23-5 / SOIC-8 options, the most widely sourced second-source for CAT24C08 footprint migration.
● M24C08-FMN6TP: STMicro 8-Kb I2C EEPROM, 1.7–5.5 V, 400 kHz, ECOPACK RoHS, available in 8-SOIC/TSSOP, a European-supply peer with comparable 1M-cycle / 100-year retention.
● PCA24C08DP: NXP 8-Kb I2C EEPROM, 1.7–5.5 V, 400 kHz, TSSOP-8 and HW-WP, often chosen when NXP ecosystem already dominates the BOM.
