# Industrial Specification: Error Detection Unit

## 1. Technical Definition
A specialized electronic component within a Protocol Handler that monitors data transmission for errors and anomalies.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **3.3-5.0 VDC at 25°C ambient, derating to 3.0-5.5 VDC at 85°C**. Failure boundary: **2.7 VDC input voltage (CMOS logic threshold violation) or 125°C junction temperature (silicon thermal runaway)**, Mechanism: **Carrier mobility degradation in MOSFET channels at elevated temperatures (Arrhenius equation: failure rate doubles per 10°C rise above 85°C)**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$  
> **Engineering Impact**: Defines the precision confidence interval for inspection.
