ATSAML10E14A-AU

Overview

The ATSAML10E14A-AU is a Microchip Technology ARM Cortex-M23 microcontroller in the SAM L10 series. It features 16 kB of Flash program memory and 8 kB of SRAM data RAM within a 32-TQFP package. The device operates at a maximum clock frequency of 32 MHz with a 32-bit data bus width. It supports a supply voltage range from 900 mV to 1.2 V and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates ARM Cortex-M23 core for efficient low-power processing
• Includes hardware security features such as AES, SHA-256, and TRNG
• Supports multiple communication interfaces including I2C, SPI, UART, and LINbus

Applications

• Smart home devices requiring secure connectivity
• Industrial sensors with low power constraints
• Wearable electronics needing compact form factors

Procurement Notes

Verify the specific suffix 'AU' corresponds to the TQFP-32 package and commercial temperature grade during procurement. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure design compatibility with the specified 900 mV to 1.2 V supply voltage range for reliable operation.

Selection Notes

Select this component when a balance of moderate code capacity and high security is required. The 16 kB Flash suits applications with limited firmware size. Consider the 32-TQFP package for surface mount assembly needs. Evaluate power consumption requirements against the Cortex-M23 efficiency profile.

Part Context

This part belongs to the SAM L10 family of microcontrollers designed for ultra-low power applications. It shares architectural similarities with the SAM L11 series but lacks some advanced cryptographic peripherals found in higher-tier models. The device targets cost-sensitive markets requiring basic security and connectivity.

Replacement Considerations

ATSAML10E15A-AU offers increased Flash memory while maintaining the same package and core architecture.
