24LC025T-I

Microchip Tech · EEPROM · TSSOP-8

24LC025T-I from Microchip Tech, in a TSSOP-8. 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 A0 input Address input A0 compared with the slave address bit to select the chip; must be connected to VCC or VSS.
2 A1 input Address input A1 compared with the slave address bit to select the chip; must be connected to VCC or VSS.
3 A2 input Address input A2 compared with the slave address bit to select the chip; must be connected to VCC or VSS.
4 VSS power_in Ground.
5 SDA bidirectional Open-drain bidirectional serial data I/O for addresses and data, requiring a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz).
6 SCL input Serial clock input used to synchronize data transfer to and from the device.
7 WP input Hardware write-protect input that must be tied to VCC (protection enabled) or VSS (disabled); not internally connected on the 24LC025.
8 VCC power_in Power supply, +1.7 to 5.5V (2.5V to 5.5V for 24LC025).
