ATSAML10E16A-AU

Overview

The ATSAML10E16A-AU is a 32-bit microcontroller from the SAM L10 series, built on the ARM Cortex-M23 core. It features 64KB of Flash memory and 16KB of SRAM. The device operates at a maximum clock speed of 32MHz with a supply voltage range of 1.62V to 3.63V. It includes an internal oscillator, 25 I/O pins, and supports interfaces such as I2C, LINbus, SPI, and UART/USART. Packaged in a TQFP-32, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates ARM Cortex-M23 processor for efficient code execution
• Includes 10-channel 12-bit ADC and one 10-bit DAC
• Supports multiple communication protocols including SPI, I2C, and USART

Applications

• Low-power embedded control systems
• Battery-operated devices requiring extended runtime
• Industrial sensor nodes with limited interface requirements

Procurement Notes

Verify the specific suffix 'AU' corresponds to the TQFP-32 package and industrial temperature grade (-40°C to +85°C) required for your design. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) during storage and handling. Ensure the ordering part number matches the exact pin count and memory configuration to avoid integration errors.

Selection Notes

Select this component when a balance of low power consumption and moderate processing capability is needed. The 32MHz speed and 64KB Flash are suitable for applications not requiring high-performance computing. Compare against the ATSAML10E16A-MUT if a smaller VQFN package is preferred over the TQFP form factor.

Part Context

This unit belongs to the Microchip SAM L10 family, designed for ultra-low power applications. It shares the Cortex-M23 architecture with other members like the ATSAML11 series but lacks the advanced cryptographic hardware found in those variants. The device targets cost-sensitive markets needing reliable 32-bit performance.

Replacement Considerations

The ATSAML10E16A-MUT serves as a direct functional alternative with identical specifications but utilizes a 32-VQFN package instead of TQFP-32.
