24AA64

Microchip Tech · Pre-ordered MCUs · PDIP-8

24AA64 from Microchip Tech, in a PDIP-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 Chip address input compared with the client address bit; must be tied to VCC or VSS for multi-device (up to eight) operation.
2 A1 input Chip address input compared with the client address bit; must be tied to VCC or VSS for multi-device (up to eight) operation.
3 A2 input Chip address input compared with the client address bit; must be tied to VCC or VSS for multi-device (up to eight) operation.
4 VSS power_in Ground.
5 SDA bidirectional Open-drain serial address/data I/O that needs a pull-up to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz).
6 SCL input Serial clock input that synchronizes data transfer to and from the device.
7 WP input Write-protect input that must be tied to VSS (writes enabled) or VCC (writes inhibited, reads unaffected).
8 VCC power_in Power supply; 1.7V to 5.5V for 24AA64.
