AT24C01C-SSHM-T

Microchip · EEPROM · SOIC-8

AT24C01C-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. Hard-wired to VCC or GND to set one of eight I2C slave addresses (0xA0..0xAE); compared against the A0 bit of the device-address byte before the EEPROM acknowledges. High-impedance input, VIL <= 0.3VCC, VIH >= 0.7VCC.
2 A1 input Device address input bit 1. Hard-wired to VCC or GND to select the slave address; compared against the A1 bit of the device-address byte. Input capacitance ~6 pF.
3 A2 input Device address input bit 2. Hard-wired to VCC or GND to select the slave address; compared against the A2 bit of the device-address byte. Input capacitance ~6 pF.
4 GND power_in Ground reference (0 V) for the device.
5 SDA bidirectional I2C serial data. Bidirectional, open-drain; requires an external pull-up to VCC. May be wire-ORed with other open-drain/open-collector devices. Schmitt-trigger input with noise filtering. VOL <= 0.4 V at IOL = 2.1 mA (VCC = 3.0V).
6 SCL input I2C serial clock input. Positive-edge clocks data into the EEPROM and negative-edge clocks data out. Schmitt-trigger, filtered input. Supports up to 400 kHz at 1.7V and 1 MHz at 2.5V/2.7V/5.0V.
7 WP input Write Protect. Tie to GND for normal read/write; tie to VCC to hardware-protect the full array against writes (per Table 4-1). No internal pull-up/down - must be driven.
8 VCC power_in Supply voltage. Operating range 1.7 V to 5.5 V. ICC ~1.0 mA (read at 400 kHz, 5.0V), ~3.0 mA (write at 400 kHz, 5.0V); standby current 1.0/2.0/6.0 uA at 1.7/2.5/5.5 V. A local 0.1 uF decoupling capacitor to GND is recommended.
