ATSAML11D15A-MUKPH

Overview

The ATSAML11D15A-MUKPH is a 32-bit microcontroller from the SAM L11 family, built on the ARM Cortex-M23 core. It operates at a maximum frequency of 32MHz and includes 32KB of Flash memory, 8KB of SRAM, and 2KB of EEPROM. The device features five 12-bit ADC channels and one 10-bit DAC. It supports I2C, LINbus, SPI, and UART/USART interfaces within a 24-VQFN package.

Feature Summary

• Integrates TrustZone-M security architecture for hardware isolation
• Includes pre-configured Secure Thingz Secure Deploy keys
• Supports low-power operation with multiple sleep modes

Applications

• Secure IoT sensor nodes
• Low-power wearable devices
• Industrial control systems requiring hardware security

Procurement Notes

Verify the specific KPH suffix indicates factory-programmed secure keys via official Microchip documentation. Confirm the package type matches the design requirements. Check current availability status as supply levels may vary. Ensure compatibility with existing development tools and software support packages before procurement.

Selection Notes

Select this model when hardware-level security is mandatory for the application. The pre-provisioned keys simplify the deployment process compared to user-programmable variants. Consider the 24-pin VQFN footprint for space-constrained designs. Evaluate power consumption requirements against the available low-power modes.

Part Context

This component belongs to the SAM L11 series, which distinguishes itself from the SAM L10 series by including two Memory Protection Units (MPUs) and three Debug Access Levels (DAL). The series targets applications needing robust security features integrated directly into the silicon without external components.

Replacement Considerations

ATSAML11E15A-UUTKPH offers similar security features but in a WLCSP-32 package with 25 I/O lines.
