HX24C128DRG

HANSCHIP semiconductor · EEPROM · SOP-8

HX24C128DRG from HANSCHIP semiconductor, in a SOP-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 that can be hardwired to select one of up to four devices on a bus, or left floating, in which case it is internally pulled down to GND.
2 A1 input Device address input that can be hardwired to select one of up to four devices on a bus, or left floating, in which case it is internally pulled down to GND.
3 NC unconnected No connect pin per the datasheet pin table.
4 GND power_in Ground reference for the device.
5 SDA bidirectional Bidirectional open-drain serial data line that may be wire-ORed with other open-drain or open-collector devices; SDA may change only while SCL is low.
6 SCL input Serial clock input; data is clocked into the EEPROM on the SCL positive edge and clocked out on the negative edge.
7 WP input Write protect input: connected to GND allows normal write operations, while connected to VCC inhibits all writes to the memory; if floating it is internally pulled down to GND.
8 VCC power_in Power supply, 1.8 V to 5.5 V operation.
