HX24C256DRG

HANSCHIP semiconductor · EEPROM · SOP-8

HX24C256DRG from HANSCHIP semiconductor, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device address input bit 0. Hardwire to VCC or GND to set one of the device address bits; may be left floating (internal pull-down to GND when board VCC-plane capacitive coupling is <3 pF). Combined with A1 to select one of up to 4 devices on the same I2C bus.
2 A1 input Device address input bit 1. Hardwire to VCC or GND to set the device I2C address; may be left floating (internal pull-down to GND under low coupling conditions).
3 NC unconnected No connect. Leave floating or tie to GND.
4 GND power_in Ground reference for the device.
5 SDA bidirectional Serial data line for the two-wire I2C interface. Open-drain output, requires an external pull-up resistor (typ. to VCC). Bi-directional; can be wire-ORed with other open-drain devices.
6 SCL input Serial clock input for the two-wire I2C interface. Data is clocked into the EEPROM on the positive edge and out on the negative edge. Supports 1 MHz @ 5V, 400 kHz @ 1.8/2.7/3.3V.
7 WP input Write Protect. Tie to GND for normal read/write operation; tie to VCC to inhibit all write operations (full 256K array protected). Internal pull-down to GND when board VCC-plane capacitive coupling is <3 pF; recommend tying to GND if coupling is >3 pF.
8 VCC power_in Power supply input. Wide operating range 1.8V to 5.5V. Absolute maximum +6.5V.
