BL24C08F-SFRC

BL(Shanghai Belling) · EEPROM · TSSOP-8

BL24C08F-SFRC from BL(Shanghai Belling), in a TSSOP-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 NC unconnected No connect pin shown on the 8-lead TSSOP pin configuration; no function is described in the pin table.
2 NC unconnected No connect pin shown on the 8-lead TSSOP pin configuration; no function is described in the pin table.
3 A2 input Device address input hard-wired to set the device address, allowing two 8K devices on one bus; floats to logic low through an internal circuit.
4 GND power_in Ground.
5 SDA bidirectional Bidirectional serial data pin, open-drain driven and can be wire-ORed with other open-drain or open-collector devices; needs an external pull-up.
6 SCL input Serial clock input that clocks data into the EEPROM on the positive edge and out on the negative edge.
7 WP input Write protect input: connected to GND allows normal read/write operations, connected to VCC write-protects the full 8K array.
8 VCC power_in Power supply, 1.7V to 5.5V at 400kHz or 2.5V to 5.5V at 1MHz.
