P24C256B-SSH-MIR from PUYA, 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 | E0 | input | Device address input bit 0. Hardwired to VCC or VSS to set the chip's I2C slave address (combined with E1/E2 allows up to 8 devices on one bus). Internally pulled down to VSS when left floating. |
| 2 | E1 | input | Device address input bit 1. Hardwired to VCC or VSS to set the chip's I2C slave address (combined with E0/E2 allows up to 8 devices on one bus). Internally pulled down to VSS when left floating. |
| 3 | E2 | input | Device address input bit 2. Hardwired to VCC or VSS to set the chip's I2C slave address (combined with E0/E1 allows up to 8 devices on one bus). Internally pulled down to VSS when left floating. |
| 4 | VSS | power_in | Ground reference (0 V) for the device. |
| 5 | SDA | bidirectional | Serial data input/output for the I2C bus. Open-drain output; requires an external pull-up resistor (typical 1.3 kΩ at 2.5-5.5V or 10 kΩ at 1.7V per AC characteristics). |
| 6 | SCL | input | Serial clock input for the I2C bus. Data is clocked in on the positive edge and out on the negative edge. Max clock 400 kHz (1.7-2.5V) or 1 MHz (2.5-5.5V). |
| 7 | WCB | input | Write Control (active low). Tie to VSS to allow normal write operations; tie to VCC to write-protect the entire memory array. Internally pulled down to VSS when left floating. |
| 8 | VCC | power_in | Supply voltage input. Operating range 1.7V to 5.5V (M grade); absolute maximum 6.25V. Typical read current 0.2 mA and write current 0.8 mA at 400 kHz. |
