ATSAML11D15A-YUT

Overview

The ATSAML11D15A-YUT is a 32-bit microcontroller from the SAM L11 family, featuring an ARM Cortex-M23 core operating at 32MHz. It integrates 32KB of flash memory, 8KB of SRAM, and 2K x 8 EEPROM. The device supports supply voltages between 1.62V and 3.63V and includes five 12-bit ADC channels and one 10-bit DAC. Connectivity options comprise I2C, LINbus, SPI, and UART/USART interfaces. It offers 17 general-purpose I/O pins and is housed in a 24-SSOP package with an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates ARM TrustZone technology for hardware-based security isolation
• Includes Peripheral Touch Controller (PTC) for capacitive touch sensing applications
• Features integrated cryptographic engine for secure data processing

Applications

• Secure consumer electronics requiring code protection
• Industrial control systems utilizing LINbus communication
• Battery-powered devices leveraging ultra-low-power modes

Procurement Notes

Verify the specific suffix 'YUT' corresponds to the 24-SSOP package variant, as other suffixes like 'MUT' indicate QFN packages. Confirm that the required revision level matches current production status. Ensure design-in documentation references the correct SAM L11 datasheet for pinout accuracy. Validate that the 24-pin SSOP footprint aligns with PCB layout constraints.

Selection Notes

Select this model when a 24-pin SSOP package is preferred over QFN or TQFP alternatives within the SAM L11 series. Choose this part if the application requires exactly 32KB flash and 17 I/O lines. Consider this MCU for designs needing integrated PTC functionality without external touch controllers. Verify voltage requirements against the 1.62V to 3.63V operational range.

Part Context

This component belongs to the Microchip SAM L11 series of ultra-low-power microcontrollers. It shares the same core architecture and peripheral set as the ATSAML11D15A-MU but differs in packaging. The series is designed for applications demanding high security and low energy consumption. It competes in the market for secure, battery-operated embedded systems.

Replacement Considerations

ATSAML11D15A-MU offers identical electrical specifications but uses a VQFN-24 package instead of SSOP. ATSAML10D15A-YUT provides similar performance but lacks the TrustZone security features found in the L11 series. Cross-referencing pinouts is essential due to package differences.
