BL24C64A-PARC

BL Shanghai Belling · EEPROM · SOP-8

BL24C64A-PARC from BL Shanghai Belling, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device address input bit 0. Hardwired to VCC or GND to set the chip's 3-bit slave address, allowing up to 8 devices on the same I2C bus. Internally biased to logic low if left floating.
2 A1 input Device address input bit 1. Hardwired to VCC or GND to set the chip's slave address. Internally biased to logic low if left floating.
3 A2 input Device address input bit 2. Hardwired to VCC or GND to set the chip's slave address. Internally biased to logic low if left floating.
4 GND power_in Ground reference for the EEPROM. Connect to system ground (0 V).
5 VCC power_in Positive power supply, 1.7 V to 5.5 V. ICC (read at 400 kHz) is typically 0.14 mA; write current is typically 0.28 mA; standby is ~0.03 uA.
6 WP input Write Protect input. Tie to GND for normal read/write operation; tie to VCC to write-protect the entire memory array (hardware data protection). Schmitt-trigger, filtered input.
7 SCL input I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Supports up to 1 MHz at VCC >= 2.5 V (400 kHz at VCC < 2.5 V). Requires an external pull-up resistor.
8 SDA bidirectional I2C serial data line, bidirectional. Open-drain output; requires an external pull-up resistor. Can be wire-OR'd with other open-drain / open-collector devices on the bus.

CAD (KiCad official)

  • Symbol: BL24C64A-PARC
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: bl24c64a-parc-etched.step / bl24c64a-parc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl24c64a-parc.step / bl24c64a-parc.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
bl24c64a-parc.step 122 KB You want the bare part, or you mark your own boards.
bl24c64a-parc-etched.step 2.3 MB You want the part with BL24C64A-PARC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 591 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
