BL25CM2A-PARC

BL(Shanghai Belling) · EEPROM · SOP-8

BL25CM2A-PARC from BL(Shanghai Belling), 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 CS input Chip Select enables and disables device operation; when high the device is deselected and SO is high impedance, and after power-up CS must transition from high to low before a new instruction is accepted.
2 SO output Serial Data Output shifts data or status out on the falling edge of the clock and is high impedance when CS is high or HOLD is low.
3 WP input Write Protect is used with the SRWD bit so that hardware write protection is active when WP is low and SRWD is 1, blocking writes to the status register and protected blocks.
4 VSS power_in Ground reference pin for the device.
5 SI input Serial Data Input receives write instructions, addresses or data on the rising edge of the Serial Clock SCK.
6 SCK input Serial Clock provides the timing for serial input and output operations.
7 HOLD input HOLD is active low and pauses device operation while CS is low; SO goes high impedance and SI and SCK are ignored while HOLD is low.
8 VCC power_in Power supply pin; the device operates from 2.8 V to 5.5 V.
