AT24C32E-SSHM-T

Microchip · EEPROM · SOIC-8

AT24C32E-SSHM-T from Microchip, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device address input bit 0. Sets the fifth bit (LSB of hardware slave address) of the I2C 7-bit slave address, allowing up to 8 devices on the same bus. Tie to VCC or GND; if left floating an internal pull-down biases it to logic 0 (pull-down disengages once driven above ~0.5 x VCC).
2 A1 input Device address input bit 1. Sets the sixth bit of the I2C 7-bit slave address. Tie to VCC or GND; internally pulled down to GND if left floating.
3 A2 input Device address input bit 2. Sets the seventh bit of the I2C 7-bit slave address. Tie to VCC or GND; internally pulled down to GND if left floating.
4 GND power_in Ground reference for the power supply. Must be connected to the system ground.
5 SDA bidirectional I2C serial data. Open-drain bidirectional input/output used to transfer data to and from the device. Requires an external pull-up resistor (not to exceed 10 kOhm) and may be wire-ORed with other open-drain devices on the bus.
6 SCL input I2C serial clock input from the bus master. Command and address data on SDA are latched on the rising edge of SCL; output data is clocked out on the falling edge. Must be driven high or externally pulled up when the bus is idle.
7 WP input Write Protect input. When tied to GND, normal write operations are permitted; when tied to VCC, all write operations to the memory array are inhibited (active high). Internally pulled down to GND when left floating.
8 VCC power_in Device power supply. Operating range 1.7 V to 3.6 V (1 MHz FM+ mode requires 2.5 V to 3.6 V). Recommend local 0.1uF bypass capacitor to GND.
