BL24C32F-RRRC

BL(Shanghai Belling) · EEPROM · TSOT-23-5L

BL24C32F-RRRC from BL(Shanghai Belling), in a TSOT-23-5L. 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 SCL input Serial clock input that positive-edge clocks data into the EEPROM and negative-edge clocks data out.
2 GND power_in Ground.
3 SDA bidirectional Bidirectional open-drain serial data pin that may be wire-OR'ed with other open-drain or open-collector devices and needs an external pull-up.
4 VCC power_in Power supply, 1.7V to 5.5V at 400kHz or 2.5V to 5.5V at 1MHz.
5 WP input Write protect input: connected to GND allows normal read/write operations, connected to VCC write-protects the full 32K array.
