Cold Chain Asset Tracking: Lapis Technology’s Low‑Power Data Logging Solution

Introducing Lapis Technology’s Low‑Power Cold Chain Asset Tracker

Cold chain logistics are critical for any product that degrades if exposed to temperature fluctuations. From perishable foods to life‑saving pharmaceuticals, maintaining the required temperature range throughout the supply chain guarantees product integrity and compliance with regulatory standards. Lapis Technology, a brand of the ROHM Group, offers a comprehensive, low‑power data‑logging solution that meets and exceeds these stringent requirements.

Why Accurate Temperature Monitoring Matters

Regulators such as the FDA mandate continuous temperature tracking for food, drugs, and cosmetics. For example, Pfizer’s COVID‑19 vaccine must remain at –70 °C from manufacture to administration. Failure to maintain this temperature can compromise vaccine efficacy and patient safety. Real‑time data capture, paired with robust historical logs, provides audit‑ready evidence of compliance.

Key Features of the Lapis Cold‑Chain Data Logger

• Ultra‑low power microcontroller – The ML630Q466/Q464 ARM Cortex‑M0+ runs on minimal current, enabling battery operation for weeks or months.
• Integrated USB 2.0 interface – Generates PDF logs that are instantly readable via a standard USB connection, meeting the US cold‑chain standard established in the 1990s.
• High‑density memory – Choose between 64 KB or 128 KB Flash ROM to accommodate custom algorithms and extended data storage.
• Built‑in LCD driver and RC‑ADC – Precise temperature measurement and on‑board display reduce external component count.
• Multiple serial ports – Connects up to three sensors for temperature, acceleration, pressure, or magnetic field data.
• Power‑saving modes – Deep‑sleep and clock gating extend battery life for remote, long‑term deployments.

Complementary Sensors for Comprehensive Asset Tracking

ROHM’s sensor portfolio includes:

• Accelerometers – detect motion, free‑fall, and machine health.
• Ambient light & RGB color sensors – monitor environmental lighting and product color changes.
• Barometric pressure sensors – track altitude changes for indoor navigation.
• Hall ICs & magnetometers – enable door status, contactless switching, and compass functionality.

Embedding IoT Connectivity

Beyond USB, the data logger can be paired with wireless modules such as Sigfox, Wi‑SUN, or Bluetooth Low Energy, all offered by Lapis. These protocols enable real‑time alerts, fleet‑wide analytics, and seamless integration with supply‑chain management systems.
