AT24C64D-XHM-T

Microchip Tech · EEPROM · TSSOP-8

AT24C64D-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 GND or VCC, internally pulled to GND if left floating, and Atmel recommends connecting it to a known state with a pull-up of 10k or less.
2 A1 input Device address input hard-wired to GND or VCC, internally pulled to GND if left floating, and Atmel recommends connecting it to a known state with a pull-up of 10k or less.
3 A2 input Device address input hard-wired to GND or VCC, internally pulled to GND if left floating, and Atmel recommends connecting it to a known state with a pull-up of 10k or less.
4 GND power_in Ground reference for the device; the voltage on any pin is rated from -1.0 V to +7.0 V with respect to ground.
5 SDA bidirectional Open-drain bidirectional serial data pin that may be wire-ORed with other open-drain or open-collector devices and requires an external pull-up because SDA is normally pulled high.
6 SCL input Serial clock input: data is positive-edge clocked into the device and negative-edge clocked out of the device.
7 WP input Write protect input: connected to GND allows normal write operations, connected to VCC inhibits all writes to the memory, and Atmel recommends a known state with a pull-up of 10k or less.
8 VCC power_in Device power supply, specified for 1.7 V to 5.5 V operation.
