BL24CM2A-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 | NC | unconnected | No internal connection. May be left floating or tied to GND. |
| 2 | NC | unconnected | No internal connection. May be left floating or tied to GND. |
| 3 | A2 | input | Device address input (hard-wired). Selects between up to two BL24CM2A devices on the same I2C bus (combined with an internal word-address bit). Internally biased to logic low if left floating; VIL <= VCC0.3, VIH >= VCC0.7. |
| 4 | GND | power_in | Ground / VSS reference (0 V). |
| 5 | SDA | bidirectional | I2C serial data. Open-drain, bidirectional; requires an external pull-up resistor to VCC and may be wire-ORed with other open-drain/open-collector devices. Schmitt-trigger filtered input; C_IO ~= 8 pF. |
| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Schmitt-trigger input, up to 1 MHz; C_IN ~= 6 pF. |
| 7 | WP | input | Write Protect. When tied to GND, normal read/write to the full 2 Mbit array is enabled. When tied to VCC, the entire memory array is write-protected (read-only). Schmitt-trigger input. |
| 8 | VCC | power_in | Positive supply, +2.8 V to +5.5 V (absolute max +6.5 V). Typical read current 0.26 mA @ 400 kHz, write current 0.56 mA, standby 0.03 uA. |
