HK24C64HA-UTR-B from HK, 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 (chip select) hardwired to VIH or VIL; recognized as VIL if left unconnected. |
| 2 | A1 | input | Device address input (chip select) hardwired to VIH or VIL; recognized as VIL if left unconnected. |
| 3 | A2 | input | Device address input (chip select) hardwired to VIH or VIL; recognized as VIL if left unconnected. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | Serial data line, bi-directional open-drain output that can be wire-ORed with other open-drain devices and is typically pulled high by an external resistor. |
| 6 | SCL | input | Serial clock input; rising edge latches data into the EEPROM and falling edge clocks data out. |
| 7 | WP | input | Write protect input; programming is disabled when connected to VIH or VCC and allowed when left unconnected or at VIL, reads unaffected. |
| 8 | VCC | power_in | Power supply, 1.8V to 5.5V. |
