Overview
The ATSAM4SD32CA-AUR is a 32-bit microcontroller from the SAM4S family, featuring an ARM Cortex-M4 core operating at 120 MHz. It integrates 2 MB of embedded Flash memory and 160 KB of SRAM within a 100-pin LQFP package. The device supports a supply voltage range of 1.62 V to 3.6 V and operates between -40°C and +85°C. Key peripherals include USB 2.0, multiple communication interfaces, and a Static Memory Controller.
Feature Summary
- Dual-bank Flash architecture with cache support for enhanced code execution efficiency
- Integrated Static Memory Controller supporting SRAM, PSRAM, NOR, and NAND Flash
- Built-in USB 2.0 Device interface with on-chip transceiver and FIFO buffer
- Comprehensive power management including sleep modes and backup mode capabilities
Applications
- Smart energy metering systems requiring secure data handling
- Industrial control applications utilizing static memory expansion
- Consumer electronics devices needing USB connectivity
- Automotive infotainment subsystems
Procurement Notes
Verify the specific suffix 'AUR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status matches current regulatory requirements. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Cross-reference the full part number with official Microchip documentation to confirm pinout compatibility with existing designs.
Selection Notes
Select this component when high-performance processing combined with large memory capacity is required. The dual-core capability distinguishes it from single-core SAM4S variants. Consider the 100-pin package constraints for PCB layout. Evaluate peripheral needs against available USART, SPI, and I2C channels before finalizing the choice.
Part Context
This MCU belongs to the SAM4S series, designed for cost-sensitive applications demanding Cortex-M4 performance. It serves as a bridge between entry-level MCUs and higher-end SAM4E or SAM4C families. The device emphasizes integration of security features and external memory access through its dedicated controller.
Replacement Considerations
ATSAM4SD32CA-AU is the tray-packaged equivalent. ATSAM4SD32CB offers alternative packaging options. Verify pin-to-pin compatibility with SAM3N and SAM3S products if migrating from legacy platforms.
