BR25A256FJ-3MGE2

ROHM Semicon · EEPROM · SOIC-8

BR25A256FJ-3MGE2 from ROHM Semicon, in a SOIC-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 CSB input Chip select input.
2 SO output Serial data output, output in sync with the falling edge of SCK.
3 WPB input Write protect input; Write status register command is prohibited.
4 GND power_in All input/output reference voltage, 0V.
5 SI input Op code, address, and serial data input, taken in on the rising edge of SCK.
6 SCK input Serial clock input.
7 HOLDB input Hold input; command communications may be suspended temporarily (HOLD status).
8 Vcc power_in Power source to be connected, 2.5V to 5.5V operation.
