24AA025T-I

Microchip Tech · EEPROM · SOT-23-6

24AA025T-I from Microchip Tech, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SCL input Serial Clock input synchronizes data transfer to and from the device, and the 24AA025 is rated for 400 kHz maximum clock (100 kHz for VCC < 2.5V).
2 VSS power_in Ground reference pin for the device.
3 SDA bidirectional Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typical 10 k for 100 kHz and 2 k for 400 kHz), and SDA may change only while SCL is low except for Start and Stop conditions.
4 A1 input Chip address input compared with the corresponding client address bit, which must be connected to either VCC or VSS.
5 A0 input Chip address input compared with the corresponding client address bit, which must be connected to either VCC or VSS.
6 VCC power_in Power supply, rated 1.7V-5.5V for the 24AA025; the internal erase/write logic is disabled if VCC is below 1.5V at nominal conditions.
