ATSAML10E14A-MUT

Overview

The ATSAML10E14A-MUT is a 32-bit ARM Cortex-M23 microcontroller from the SAM L10 family, manufactured by Microchip Technology. It features 16 kB of Flash program memory and 4 kB of SRAM data RAM. The device operates with a maximum clock frequency of 32 MHz and supports a supply voltage range of 1.62 V to 3.63 V. It is housed in a 32-VQFN (5x5) package with 25 I/O pins. The component includes an internal oscillator and supports interfaces such as I2C, LINbus, SPI, and UART/USART.

Feature Summary

• Integrates hardware security features including AES, SHA-1/SHA-256, and True Random Number Generator for secure boot and cryptographic operations.
• Provides multiple low-power operating modes including Run, Idle, Sleep, Standby, and HIBERNATE to optimize energy consumption.
• Includes analog peripherals such as five 12-bit ADC channels and one 10-bit DAC for signal processing applications.

Applications

• Secure IoT sensor nodes requiring encrypted communication
• Battery-powered wearable devices utilizing low-power modes
• Industrial control systems using LINbus or SPI interfaces
• Smart home appliances with cryptographic authentication needs

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging format as indicated in official documentation. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the 32-VQFN footprint matches your PCB design guidelines. Cross-reference the datasheet revision to confirm peripheral availability and errata conditions before finalizing procurement.

Selection Notes

Select this model when 16 kB of Flash and 4 kB of SRAM are sufficient for application code and data storage. Choose the 32-VQFN package if board space constraints require a compact form factor with 25 available I/O pins. Consider this part over other SAM L10 variants if the specific combination of crypto peripherals and low-power features aligns with security-critical embedded designs without requiring larger memory capacities.

Part Context

This component belongs to the Microchip SAM L10 series of Arm Cortex-M23 microcontrollers. The series is designed for cost-sensitive and power-efficient applications. The ATSAML10E14A-MUT specifically denotes the variant with 16 kB Flash, 4 kB SRAM, and the E package outline. It shares the core architecture with other members like ATSAML10D14A but differs in memory size and package type.

Replacement Considerations

ATSAML10D14A-MUT offers similar functionality but in a smaller 24-VQFN package with identical memory. ATSAML10E15A-MU provides increased memory (32 kB Flash, 8 kB SRAM) in the same 32-VQFN package. Verify pin compatibility and software configurability when substituting within the SAM L10 family.
