HK24C64HA-UTR-B

HK · EEPROM · TSSOP-8

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.
