Overview
The ATSAM4SD16BA-MU is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at frequencies up to 120 MHz. It features 1 Mbyte of embedded Flash memory and 160 Kbytes of SRAM. The device includes an integrated Static Memory Controller (SMC) supporting external memory interfaces such as SRAM, PSRAM, NOR, and NAND Flash. Connectivity options include USB 2.0 Device capabilities with up to eight bidirectional endpoints, multiple USARTs, SPI, I2C, and SSC interfaces. The component operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates an ARM Cortex-M4 processor with a 2 Kbyte cache and DSP instruction set for high-performance execution.
- Provides extensive connectivity through USB 2.0, multiple serial communication peripherals, and a Static Memory Controller for external storage expansion.
- Supports low-power operation with Sleep and Backup modes, featuring an ultra-low-power Real-Time Clock.
Applications
- Industrial control systems requiring robust peripheral interfaces
- Medical devices utilizing internal calibration and safety features
- Consumer electronics with USB connectivity requirements
Procurement Notes
Verify the specific suffix 'MU' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the designated package. Confirm that the required Flash and RAM capacities align with application needs before procurement.
Selection Notes
Select this component when a balance of processing power and external memory expansion is required. The inclusion of the Static Memory Controller allows for flexible system design involving external storage. Verify that the 120 MHz clock speed meets real-time processing constraints.
Part Context
This part belongs to the SAM4S series of microcontrollers, which are pin-to-pin compatible with SAM3N and SAM3S products. The series utilizes the ARM Cortex-M4 architecture, offering enhanced performance over previous generations while maintaining software compatibility with established development frameworks.
Replacement Considerations
Consult official substitution lists for verified alternatives. Cross-reference pinouts and electrical specifications if considering similar models within the SAM4 family.
