24AA16H-I

Microchip Tech · EEPROM · SOIC-8

24AA16H-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 unconnected Not used by the 24XX16H (no internal connection); may be left floating or tied to VSS or VCC.
2 A1 unconnected Not used by the 24XX16H (no internal connection); may be left floating or tied to VSS or VCC.
3 A2 unconnected Not used by the 24XX16H (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 (full memory 000-7FF writable) or VCC (write operations inhibited for half the memory, 400h-7FFh; reads unaffected).
8 VCC power_in Power supply, 1.7V-5.5V for 24AA16H (2.5V-5.5V for 24LC16BH).
