HG25Q128BMW

HGSEMI · NOR FLASH · SOP-8-208mil

HG25Q128BMW from HGSEMI, in a SOP-8-208mil. 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 CS# input Chip Select input; serial access to the device is enabled by CS#, and the device goes to standby mode when CS# is high.
2 SO/SIO1 bidirectional Serial Data Output for 1 x I/O, or Serial Data Input & Output for 2 x I/O or 4 x I/O read mode.
3 WP#/SIO2 bidirectional Write Protection (active low) or Serial Data Input & Output for 4 x I/O read mode; has an internal pull-up when not physically connected.
4 GND power_in Ground.
5 SI/SIO0 bidirectional Serial Data Input for 1 x I/O, or Serial Data Input & Output for 2 x I/O or 4 x I/O read mode.
6 SCLK input Serial clock input.
7 RESET#/SIO3 bidirectional Hardware Reset (active low) or Serial Data Input & Output for 4 x I/O read mode; must be connected to VCC (not floating) if neither 4 x I/O nor hardware reset is used.
8 VCC power_in +3V power supply; 2.7 V to 3.6 V for read, erase and program operations.
