AT24CS08-SSHM-T

Microchip Tech · EEPROM · SOIC-8

AT24CS08-SSHM-T from Microchip Tech, in a SOIC-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 NC unconnected No connect on the AT24CS08; the datasheet states pins 1 and 2 are no connects and can be connected to ground.
2 A1/NC unconnected Not used on the 8-Kbit AT24CS08 (no connect, may be tied to ground); the A1 address input applies only to the 4-Kbit AT24CS04.
3 A2 input Hardwired device address input that must match the A2 bit in the device address word; the AT24CS08 uses it to address one of two 8K devices on a bus.
4 GND power_in Ground reference pin for the device.
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.
6 SCL input Serial clock input: data is positive-edge clocked into the EEPROM and negative-edge clocked out of it.
7 WP input Write protect: tied to GND allows normal read/write to the full array, while tied to VCC inhibits all write operations and reads remain possible.
8 VCC power_in Power supply, specified from 1.7 V to 5.5 V.
