ATSAML11E14A-MUT

Overview

The ATSAML11E14A-MUT is a 32-bit microcontroller from the SAM L11 family, featuring an ARM Cortex-M23 core operating at 32MHz. It integrates 16KB of Flash memory, 4KB of SRAM, and 2KB of EEPROM. The device supports a supply voltage range of 1.62V to 3.63V and includes ten 12-bit ADC channels and one 10-bit DAC. Connectivity options include I2C, LINbus, SPI, and UART/USART interfaces. It is housed in a 32-VQFN (5x5) package with 25 I/O pins and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates hardware security features including AES, SHA-256, and True Random Number Generator for secure boot and data protection.
• Features low-power operation modes such as Sleep, Idle, and Standby to optimize energy consumption in battery-powered applications.
• Includes advanced analog peripherals like comparators and touch sensing capabilities for user interface interactions.

Applications

• Secure smart metering and utility metering devices
• Industrial control systems requiring secure communication
• Consumer electronics with tamper-resistant requirements

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 32-VQFN package and tape-and-reel packaging format. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to PCB assembly planning. Ensure design compatibility with the 1.62V to 3.63V supply voltage range and check for any recent Product Change Notifications affecting assembly sites or materials.

Selection Notes

Select this component when a balance of moderate code storage (16KB) and robust security features is required. It serves as a suitable upgrade path from 8-bit MCUs needing enhanced processing power and cryptographic capabilities. Consider alternative pin counts or memory sizes within the SAM L11 family if I/O count or storage requirements exceed these specifications.

Part Context

This part belongs to the Microchip SAM L11 family of Arm Cortex-M23 microcontrollers designed for cost-sensitive, secure embedded applications. The family shares common peripheral sets and software libraries, facilitating migration between different memory variants while maintaining pin-to-pin compatibility where package types align.

Replacement Considerations

Direct substitutes within the same package may include ATSAML11D14A-MUT (lower RAM) or ATSAML11E16A-MUT (higher Flash/RAM). Verify functional equivalence regarding security feature availability and peripheral configuration before substitution.
