BR25H080FJ-2CE2

ROHM Semicon · EEPROM · SOIC-8

BR25H080FJ-2CE2 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; set LOW to start a command, as described for the read and write command cycles.
2 SO output Serial data output, shifted out on the falling edge of SCK starting from the MSB.
3 WPB input Write protect input; when LOW it prohibits the write status register command, but only when the WPEN bit is set to 1.
4 GND power_in Input/output reference voltage, 0 V.
5 SI input Start bit, op code, address and serial data input, latched on the rising edge of SCK starting from the MSB.
6 SCK input Serial clock input, up to 10 MHz (max).
7 HOLDB input Hold input; when driven LOW while SCK is LOW, command communication is suspended temporarily (HOLD status).
8 VCC power_in Power supply, 2.5 V to 5.5 V.
