AT24C02C-XHM-T

Microchip Tech · EEPROM · TSSOP-8

AT24C02C-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 select the device; its state must match the A0 bit in the device address word for the chip to acknowledge.
2 A1 input Device address input hard-wired to select the device; its state must match the A1 bit in the device address word for the chip to acknowledge, and up to eight 2-Kbit devices can share one bus.
3 A2 input Device address input hard-wired to select the device; its state must match the A2 bit in the device address word for the chip to acknowledge.
4 GND power_in Ground reference for the device; the absolute maximum voltage on any pin is rated from -1.0V to +7.0V with respect to ground.
5 SDA bidirectional Bidirectional serial data pin that is open drain driven and may be wire-ORed with other open drain or open collector devices; it is normally pulled high externally and may change only while SCL is low.
6 SCL input Serial clock input: data is positive-edge clocked into the device and negative-edge clocked out, with fSCL up to 400 kHz at 1.7V and 1000 kHz at 2.5V/5.0V.
7 WP input Write Protect input: connecting it to GND allows normal read/write operation, while connecting it to VCC enables hardware write protection of the full 2K array.
8 VCC power_in Power supply pin; the device operates from VCC = 1.7V to 5.5V (recommended operating range).
