# Industrial Specification: I/O Interface Block

## 1. Technical Definition
A specialized circuit block within an Array Processor or ASIC that manages data input and output operations between the processor core and external devices.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2V input voltage, -40°C to +125°C ambient temperature, 0-100MHz signal frequency**. Failure boundary: **Input voltage exceeding 1.5V causes gate oxide breakdown, junction temperature surpassing 150°C triggers thermal runaway, signal frequency above 120MHz induces timing violations**, Mechanism: **Electromigration at current densities &gt; 1×10⁶ A/cm², hot carrier injection at electric fields &gt; 5×10⁶ V/cm, dielectric breakdown at electric fields &gt; 10 MV/cm**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
