Next-Generation Chip Evaluation (Atmosic & nRF54H20) — Performance, Precision, and Insight

Where This Shines

  • Not just a chip test — a deep technical evaluation of next-generation wireless MCUs.
  • We benchmarked, analyzed, and validated early silicon to guide real-world integration.
  • So our partners could build smarter, faster, and more efficiently — from day one.

⚙️ What Is Next-Generation Chip Evaluation?

Next-Generation Chip Evaluation (Atmosic & nRF54H20) was a comprehensive technical assessment project performed for a U.S.-based partner exploring new wireless MCU platforms.

We evaluated pre-release chips from Atmosic and Nordic Semiconductor (nRF54H20), focusing on performance, stability, and SDK readiness.

Testing involved detailed peripheral benchmarking — I2C, SPI, GPIO — under various operating conditions to verify functionality and timing accuracy.

We also conducted radio analysis using both Enhanced ShockBurst (ESB) and Bluetooth Low Energy (BLE) to assess throughput, range, and reliability.

By combining quantitative measurement and SDK feedback, we provided actionable insights to improve future firmware and hardware integration.

🧩 Problem

Adopting new wireless microcontrollers can be challenging due to immature SDKs, undocumented behaviors, and unverified performance claims:

  • Peripheral drivers may be incomplete or unstable
  • Radio stacks may have limited test coverage
  • Early-stage SDKs often lack optimization
  • Limited public benchmarks hinder design decisions

Without real-world validation, developers risk integration delays and inefficient hardware adoption.

Types of quality in ECG signals

💡 Our Solution

We conducted a full-spectrum evaluation of Atmosic and Nordic nRF54H20 chips, validating both hardware peripherals and radio subsystems using the latest vendor SDKs.

  • Benchmarked I2C, SPI, and GPIO performance
  • Tested BLE and ESB radio throughput, range, and stability
  • Assessed SDK functionality and identified potential bugs
  • Provided vendor feedback for firmware and API improvement
  • Delivered power and performance optimization recommendations

This process ensured an evidence-based understanding of early silicon performance and SDK reliability.
