AT24C32E-XHM-T

Microchip Tech · EEPROM · TSSOP-8

AT24C32E-XHM-T 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 Device address input, hard-wired to GND or VCC; it is internally pulled down if left floating, and Microchip recommends a pull-up of 10 kΩ or less when one is used.
2 A1 input Device address input, hard-wired to GND or VCC so that up to eight devices can share one bus; it is internally pulled down if left floating, and Microchip recommends a pull-up of 10 kΩ or less when one is used.
3 A2 input Device address input, hard-wired to GND or VCC so that up to eight devices can share one bus; it is internally pulled down if left floating, and Microchip recommends a pull-up of 10 kΩ or less when one is used.
4 GND power_in Ground reference for the power supply, which should be connected to the system ground.
5 SDA bidirectional Open-drain serial data input/output that must be pulled high through an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices on the bus.
6 SCL input Serial clock that latches SDA input on its rising edge and clocks SDA output on its falling edge; it must be held high when the bus is idle, either forced or pulled up by an external resistor.
7 WP input Write-protect input: connecting it to GND allows normal write operations, while connecting it to VCC inhibits all writes to the full array; it is internally pulled down if left floating, and a pull-up of 10 kΩ or less is recommended when used.
8 VCC power_in Device power supply pin; operating at VCC voltages outside the specified range may produce spurious results and should not be attempted.
