5.1.1.2.3. Non-functional requirements
| The USART module shall support baud rates from 1200 bps to 1 Mbps. | 
| The USART module shall maintain a communication error rate below 0.1% under normal operating conditions. | 
| The USART module shall operate with a power consumption of less than 50 mW at 3.3V during normal operation. | 
| The USART module shall operate reliably in a temperature range of -40°C to 85°C. | 
| The USART module shall transmit and receive data with a latency of no more than 5 ms. | 
| The USART module shall support stable operation with clock frequencies of up to 72 MHz. | 
| The USART module shall maintain synchronization between the transmitter and receiver within ±2% clock drift tolerance. | 
| The USART module shall provide deterministic interrupt response times of less than 2 µs when operating with an interrupt-driven configuration. |
