24AA02

Microchip Tech · Pre-ordered Chips · SOIC-8

24AA02 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 unconnected Not used by the 24XX02 (no internal connection); may be left floating or tied to VSS or VCC.
2 A1 unconnected Not used by the 24XX02 (no internal connection); may be left floating or tied to VSS or VCC.
3 A2 unconnected Not used by the 24XX02 (no internal connection); may be left floating or tied to VSS or VCC.
4 VSS power_in Ground.
5 SDA bidirectional Serial address/data I/O; open-drain, requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz).
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 tied to VSS (normal read/write of entire memory 00-FF) or VCC (write operations inhibited, reads unaffected).
8 VCC power_in Power supply, 1.7V to 5.5V for 24AA02 and 24FC02, 2.5V to 5.5V for 24LC02B.
