ATSAML10E15A-MF

Overview

The ATSAML10E15A-MF is a 32-bit microcontroller from the SAM L10 family, featuring an ARM Cortex-M23 core operating at 32 MHz. It integrates 32 KB of flash memory and 8 KB of SRAM within a VQFN-32 package. The device supports a supply voltage range of 1.62V to 3.63V and operates between -40°C and +125°C. Key peripherals include ten 12-bit ADC channels, one 10-bit DAC, DMA, SERCOM interfaces (I2C, SPI, UART), and a Programmable Touch Controller.

Feature Summary

• Integrates ARM TrustZone technology for hardware-based security isolation
• Includes a dedicated Programmable Touch Controller for capacitive sensing applications
• Supports multiple communication protocols via Serial Communication Modules
• Features low-power operation modes with fast wake-up capabilities

Applications

• Industrial control systems requiring secure embedded processing
• Smart metering devices utilizing touch interface capabilities
• Battery-powered IoT sensors needing extended operational temperature ranges
• Consumer electronics with security-sensitive data handling requirements

Procurement Notes

Verify the suffix 'MF' confirms the industrial temperature grade (+125°C max) and tray packaging format. Confirm RoHS compliance status matches current regulatory requirements. Check for any specific errata related to the silicon revision before finalizing design-in. Ensure ESD protection measures are adequate for the QFN package during assembly.

Selection Notes

Select this variant when an industrial temperature rating is mandatory for the application environment. The inclusion of TrustZone makes it suitable for projects requiring enhanced security features compared to non-secure MCU alternatives. Consider the 32-pin footprint constraints against available PCB space. Evaluate if the 32 MHz clock speed meets real-time processing demands without excessive power consumption.

Part Context

This component belongs to the Microchip SAM L10 series, designed for ultra-low-power applications. It shares architectural similarities with other Cortex-M23 based MCUs but distinguishes itself through integrated security and touch sensing peripherals. The series targets cost-sensitive markets requiring robust performance in compact form factors.

Replacement Considerations

Direct substitutes include ATSAML10E15A-MUT for tape-and-reel packaging or ATSAML10E15A-MU for commercial temperature grades. Verify pin compatibility and software register mapping before swapping variants within the same family.
