BL24C128AE0-PARC

BL(Shanghai Belling) · EEPROM · SOP-8

BL24C128AE0-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 A0 input Device address input, hard-wired; with A1 and A2 it allows up to eight devices on one bus and floats to logic low if left unconnected.
2 A1 input Device address input, hard-wired; with A0 and A2 it allows up to eight devices on one bus and floats to logic low if left unconnected.
3 A2 input Device address input, hard-wired; with A0 and A1 it allows up to eight devices on one bus and floats to logic low if left unconnected.
4 GND power_in Ground.
5 SDA bidirectional Bidirectional serial data pin, open-drain and wire-ORable with other open-drain or open-collector devices, needing an external pull-up.
6 SCL input Serial clock input that clocks data into the device on the positive edge and out on the negative edge.
7 WP input Write protect input: connected to GND it allows normal read/write operations, connected to VCC it write-protects the full 128K array.
8 VCC power_in Power supply, 1.7V to 5.5V (2.5V to 5.5V at 1 MHz).
