24AA512T-I

Microchip Tech · EEPROM · SOIC-8

24AA512T-I from Microchip Tech, in a SOIC-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 User-configured chip address input that must be connected to VCC or VSS, or driven to a defined logic level before normal operation in applications where it is controlled by a microcontroller.
2 A1 input User-configured chip address input that must be connected to VCC or VSS, or driven to a defined logic level before normal operation in applications where it is controlled by a microcontroller.
3 A2 input User-configured chip address input that must be connected to VCC or VSS, or driven to a defined logic level before normal operation in applications where it is controlled by a microcontroller.
4 VSS power_in Ground reference for the device.
5 SDA bidirectional Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz) and may change only while SCL is low, except for Start and Stop conditions.
6 SCL input Serial clock input used to synchronize data transfer to and from the device.
7 WP input Write-protect input that must be connected to VSS (writes enabled) or VCC (write operations inhibited while read operations are not affected).
8 VCC power_in Power supply input; the 24AA512 is specified for operation from 1.7V to 5.5V.
