Frequently Asked Questions
Does the solution meet AAMI/ESH/ISO 81060-2 standards?
Yes. Our solution is built on a High-Integration Medical AFE (including PGA, SCF, and Constant Current Generator) rather than a standard ADC. Combined with our proprietary oscillometric algorithms, it ensures clinical-grade signal quality and accuracy (±3mmHg pressure, ±5% heart rate), fully compliant with AAMI, ESH, and ISO 81060-2 standards.
How does this solution improve mass production efficiency?
It is designed for rapid manufacturing. The solution supports a 15-second Automated Calibration process. Our dedicated production tool allows 4 PCBAs to be calibrated simultaneously (switching between 0, 150, and 300 mmHg), significantly reducing testing time and production costs compared to traditional methods.
What battery life can be expected?
Excellent longevity. The BH67F2265 MCU features an ultra-low standby current of <1.5μA. Even with 4×AA batteries, the system can support 500+ measurements, typically lasting 1-2 years of normal home use. The dual-chip power architecture also ensures that connectivity modules (BLE) do not drain power when idle.
Is smartphone connectivity supported?
Yes, via our Flexible Dual-Chip Architecture. You can easily integrate an external BLE module with the MCU. Our platform supports seamless data transmission for trend analysis and cloud synchronization, making it ideal for modern smart healthcare applications.
Can the solution support different display types and voice features?
Absolutely. The SoC is versatile: For Cost-Efficiency: Use the single-chip solution with built-in LCD driver (64LQFP). For Premium Designs: Pair with the HT16K33A driver for stylish LED displays (32QFN). Voice Guidance: Optional Voice MCU (HT68RV03x) can be added to any configuration for clear audio prompts.
Can the MCU detect irregular heartbeat (arrhythmia)?
Yes. The built-in algorithm library includes IHB (Irregular Heartbeat) Detection. By analyzing pulse interval variations during measurement, the device automatically alerts users to potential arrhythmia risks.
Do you provide support for regulatory certification?
Yes, comprehensive support is included. We provide complete design documentation, circuit diagrams, and pre-compliance test reports. Our team offers professional consultation to assist you in navigating FDA, CE, and CFDA certification processes smoothly.
