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 | VDD_I/O | power_in | Digital interface supply voltage. Range 1.7 V to VS; typically 1.8 V. Powers the I2C/SPI I/O buffers and sets the logic level of digital pins. |+| 2 | GND | power_in | Ground. Must be connected to ground. |+| 3 | RESERVED | passive | Reserved. Must be connected to VS or left open (not connected). |+| 4 | GND | power_in | Ground. Must be connected to ground. |+| 5 | GND | power_in | Ground. Must be connected to ground. |+| 6 | VS | power_in | Analog/core supply voltage. Range 2.0 V to 3.6 V; typically 2.5 V. Main supply for the accelerometer sensor and analog front-end. |+| 7 | CS | input | Chip select (active low). Tie high (to VDD_I/O) to select I2C mode; drive from an SPI master to select SPI mode. Includes the interface-mode selector between I2C and SPI. |+| 8 | INT1 | output | Interrupt 1 output. Programmable interrupt (tap, activity/inactivity, free-fall, data ready, watermark, overrun) whose polarity is configurable via the DATA_FORMAT register. |+| 9 | INT2 | output | Interrupt 2 output. Second programmable interrupt channel; any of the same events can be routed here via the INT_MAP register. |+| 10 | NC | unconnected | No internal connection. Leave open or tie to ground for mechanical support. |+| 11 | RESERVED | passive | Reserved. Must be connected to ground or left open (not connected). |+| 12 | SDO/ALT_ADDRESS | bidirectional | In SPI 4-wire mode this is the serial data output (SDO). In I2C mode this pin selects the alternate 7-bit I2C address (tie low for 0x53, tie high for 0x1D). |+| 13 | SDA/SDI/SDIO | bidirectional | Serial data. In I2C mode this is SDA (open-drain, bidirectional). In SPI 4-wire mode this is SDI (data in to the ADXL345). In SPI 3-wire mode this pin is the bidirectional SDIO. |+| 14 | SCL/SCLK | input | Serial communications clock. SCL in I2C mode, SCLK in SPI mode. Also functions as an I2C/SPI protocol clock line shared across the two interfaces. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | LGA-14(3x5) |+| Category | Sensors |+| Pins | 14 |++## Ordering variants++Same part, different packaging or reel option.++- `ADXL345BCCZ`+- `ADXL345BCCZ-RL`+- `ADXL345BCCZ-RL7`++## CAD (KiCad official)++- Symbol: `ADXL345BCCZ`+- Footprint: `Package_LGA:LGA-14_3x5mm_P0.8mm_LayoutBorder1x6y`+- 3D model: LGA-14(3x5) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588886680593555456) (40 pp, sha256 `230a78d03d36a94d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
