Overview
The ATSAML22J16A-MUT is a 32-bit ARM Cortex-M0+ microcontroller from the Microchip SAM L22 series. It features 64 kB of Flash program memory and 8 kB of SRAM data RAM. The device operates at a maximum clock frequency of 32 MHz with a supply voltage range of 1.62 V to 3.63 V. It includes a 12-bit ADC with 16 channels, 50 general-purpose I/Os, and supports interfaces including I2C, SPI, UART, USART, and USB. The component is housed in a 64-VFQFN package with exposed pad and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates a low-power USB peripheral for connectivity applications
- Includes dedicated peripherals such as LCD controller, DMA engine, and PWM modules
- Supports multiple sleep modes to optimize energy consumption in battery-powered designs
Applications
- Battery-powered wearable devices requiring ultra-low power operation
- USB-enabled consumer electronics and peripherals
- Industrial control systems utilizing LCD displays
- Smart home automation sensors and actuators
Procurement Notes
Verify the specific suffix against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer documentation. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference part numbers with current Microchip production notices to avoid obsolete variants.
Selection Notes
Select this model when a balance of low power consumption and USB connectivity is required without complex RTOS support. The Cortex-M0+ core suits simple control tasks. Compare storage capacity against higher-density SAML22 variants if larger codebases are anticipated. Verify voltage compatibility with target system rails given the 1.62V minimum requirement.
Part Context
This MCU belongs to the SAM L22 family, designed specifically for ultra-low power applications. It shares architectural similarities with other ARM Cortex-M0+ MCUs but distinguishes itself through integrated USB capabilities and specialized low-power peripherals. It serves as a cost-effective solution for resource-constrained embedded systems needing reliable serial communication and analog input processing.
Replacement Considerations
ATSAML22J16A-AUT offers identical functional specifications but utilizes a 64-TQFP package instead of QFN. ATSAML22J18A-MUT provides increased memory capacity (256 kB Flash, 32 kB RAM) within the same QFN footprint.
