Application Specific Microcontrollers Procurement Notes

Verify package availability, as the component is offered as die (C) or wire-bonded module (M5). Confirm voltage range options (1.8V/3.0V/5.0V vs 3.0V/5.0V) and temperature grades (-25°C to +70°C or +85°C) against specific project requirements. Contact sales representatives for current ordering details and qualification reports.

Application Specific Microcontrollers Selection Notes

Select based on required operating voltage and temperature range. The internal PLL allows frequency scaling up to 33 MHz; ensure external clock sources match the 1–7.5 MHz input requirement. Consider the MMU for multi-application OS separation and the DDES accelerator for performance-critical cryptographic operations.
