Overview

DM0301 is a pin-to-pin compatible hardware replacement for ST VL53L4CD designs. It is a miniature 940 nm direct time-of-flight (dToF) sensor for single-zone proximity and distance measurement, giving OEM teams a compact path to refresh existing products with a straightforward PCB migration strategy.

Integrated optical and processing architecture

Inside the 4.40 × 2.40 × 1.00 mm package are a 940 nm VCSEL, SPAD array, microlens, time-to-digital converter, histogram memory and Arm Cortex-M0 MCU. The integrated architecture supports the same class of compact proximity and distance applications that make VL53L4CD designs attractive, while embedded crosstalk and anti-ambient-light algorithms provide a processed distance result instead of raw photon timing data.

Range with honest design limits

Engineers can configure a nominal 20 mm to 5 m range and run at up to 50 Hz. The datasheet describes accurate indoor measurement up to 4,000 mm; final performance depends on target reflectivity, ambient light, cover glass, calibration and ranging settings. For VL53L4CD replacement projects, validate the final optical stack, calibration and ranging performance in the target enclosure.

Indoor Range: Up to 4,000 mm
Frame Rate: Up to 50 Hz
Package Size: 4.40 × 2.40 × 1.00 mm
Interface: I2C, 0x41, up to 1 Mbit/s

Host Integration

DM0301 combines a 3.3 V supply domain, I2C control and a data-ready GPIO in a 12-pad optical LGA. For VL53L4CD replacement projects, pin-to-pin compatibility is the hardware starting point. Validate the 7-bit I2C address 0x41, register map, firmware timing, optical stack and final cover glass during system qualification.

VL53L4CD migration: pin-to-pin compatibility can simplify PCB reuse. Confirm the host I2C address, register map and firmware timing before production release.
Boot and firmware: after XSHUT is enabled, the host can communicate over I2C. The bootloader supports firmware transfer and then enters software standby for ranging control.
Choose a ranging mode: use single measurement, timed measurement or fixed N-frame operation to match latency and power requirements.
Read each result: poll interrupt register 0xE1 or use the active-low GPIO1 interrupt. Distance is reported in millimetres at registers 0x21-0x22, confidence at 0x23 and die temperature at 0x30.

Cover-glass and offset calibration

For best performance, calibrate the assembled optical stack under controlled conditions. The datasheet recommends offset calibration at 500 mm and requires the final cover glass to be considered. Its published no-ambient-light test setup used 90% cover-glass transmittance and a 0.36 mm air gap.

FAQs

Is DM0301 a pin-to-pin compatible replacement for ST VL53L4CD?

Yes. DOMI positions DM0301 as a pin-to-pin compatible hardware replacement for ST VL53L4CD designs. Validate the I2C address, register map, firmware timing, optical stack and final cover glass in the complete product before release.

Does the DM0301 support accurate indoor ranging up to 4 m?

Yes. The datasheet describes accurate indoor distance measurement up to 4,000 mm and a nominal configurable range from 20 mm to 5 m. Actual range depends on target reflectivity, ambient light, cover glass, calibration and ranging settings.

Is the DM0301 a Class 1 eye-safe ToF sensor?

Yes. The datasheet specifies a 940 nm VCSEL and Class 1 laser safety to IEC 60825-1:2014. OEMs should still verify eye safety for the complete product, including the final cover glass, drive configuration and mechanical assembly.

Can the DM0301 connect directly to a host MCU over I2C?

Yes. It uses a 7-bit I2C slave address of 0x41 and supports bus rates up to 1 Mbit/s. A host can read results by polling or use the active-low GPIO1 data-ready interrupt, while XSHUT controls hardware standby.

Can the DM0301 be calibrated for a product cover glass?

Yes. Cover-glass calibration is supported. The datasheet recommends offset calibration at 500 mm under controlled conditions and says the final cover glass should be included during calibration for best ranging performance.
