Overview
The ATSAML11E15A-AFTKPH is a 32-bit ARM Cortex-M23 microcontroller from the Microchip SAM L11 family. It features 32KB of flash memory and 8KB of SRAM, operating at a maximum frequency of 32MHz. The device supports a supply voltage range of 1.62V to 3.63V and includes integrated security features such as TrustZone-M and pre-provisioned keys via the KPH suffix. It offers up to 25 programmable I/O lines and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates ARM TrustZone-M technology with hardware-enforced security isolation for sensitive data protection.
- Includes pre-configured Root of Trust keys for secure boot and cryptographic operations.
- Provides enhanced positive temperature coefficient (PTC) sensors for accurate thermal monitoring.
- Supports low-power operation modes including standby with SRAM retention.
Applications
- Secure consumer electronics requiring hardware-based authentication
- Smart home devices needing encrypted communication protocols
- Industrial sensors utilizing PTC for temperature compensation
- Wearable technology demanding ultra-low power consumption
Procurement Notes
Verify the specific KPH suffix indicates factory-preloaded Trustonic keys. Confirm package type matches design requirements. Check latest datasheet for errata regarding clock configuration. Ensure development tools support the SAM L11 series. Validate RoHS compliance status before final procurement.
Selection Notes
Select this model when hardware security isolation is mandatory. Compare flash size against application code requirements. Consider pin count availability for interface needs. Evaluate power consumption in active versus sleep modes. Verify compatibility with existing debug interfaces.
Part Context
Part of the SAM L11 family designed for secure, low-power applications. Shares core architecture with ATSAML10 but adds TrustZone capabilities. Offers various memory configurations and packages. Designed for IoT and embedded security markets.
Replacement Considerations
ATSAML11E15A-MUT serves as a non-keyed alternative. ATSAML10E15A lacks TrustZone security features. Verify pin compatibility when substituting across families.
