AT24C512C-SSHM-T

Microchip · EEPROM · SOP-8

AT24C512C-SSHM-T from Microchip, in a SOP-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. Hardwire to VCC or GND to set one of up to 8 unique bus addresses; if left floating it is internally pulled to GND, but a defined connection (10 kOhm or less pull) is recommended due to capacitive coupling.
2 A1 input Device address input bit 1. Hardwire to VCC or GND to select the device address; internally pulled to GND if floating. Recommended external tie (<=10 kOhm) to a known state.
3 A2 input Device address input bit 2. Combined with A1/A0 to give up to 8 devices per I2C bus. Internally pulled to GND if floating; recommended external tie (<=10 kOhm).
4 GND power_in Device ground / 0 V reference.
5 SDA bidirectional I2C serial data. Bidirectional, open-drain output; requires an external pull-up resistor (typ 1.3 kOhm at 2.5-5V, 10 kOhm at 1.7V). Wire-ORable with other open-drain devices on the bus.
6 SCL input I2C serial clock input. Positive edges clock data into the device; negative edges clock data out. Supports up to 400 kHz at 1.7V and 1 MHz at 2.5-5.5V.
7 WP input Write Protect. Tie to GND for normal read/write operation; tie to VCC to inhibit all writes to the array (full-array protection). Internally pulled to GND if floating; recommended external tie (<=10 kOhm) to a known state.
8 VCC power_in Positive supply. 1.7-3.6V (VCC1) or 2.5-5.5V (VCC2) depending on device variant. Absolute max 6.25V.
