Overview
The ATSAM4S2BA-UUR is a 32-bit microcontroller from the Microchip SAM4S series, built on the ARM Cortex-M4 core. It operates at a maximum frequency of 120 MHz and integrates 256 KB of Flash memory with 64 KB of SRAM. The device features an internal oscillator and supports a supply voltage range of 1.62 V to 3.6 V. Connectivity options include I2C, IrDA, SPI, SSC, UART/USART, and USB interfaces. It provides 47 general-purpose I/Os and includes peripherals such as DMA, PWM, and watchdog timers. The component is housed in a 64-LQFP package and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates a high-performance 32-bit ARM Cortex-M4 processor with hardware floating-point unit for efficient code execution.
- Includes full-speed USB Device Port for direct communication without external transceivers.
- Features dual-bank Flash memory implementation with cache support to optimize instruction fetch performance.
- Supports multiple low-power modes including Idle, Wait, and Stop to minimize energy consumption.
Applications
- Industrial control systems requiring robust processing and reliable communication interfaces.
- Consumer electronics utilizing USB connectivity for data transfer or power management.
- Medical devices needing precise timing and secure data handling capabilities.
- Automotive infotainment subsystems operating under extended temperature conditions.
Procurement Notes
Verify the specific suffix 'UUR' against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 64-LQFP form factor. Check for any recent Product Change Notifications regarding assembly locations or marking changes that may affect integration timelines.
Selection Notes
Select this model when 256 KB of program storage and 64 KB of RAM are required alongside USB functionality. Compare against the ATSAM4S4BA series if higher I/O counts or additional DAC channels are necessary. Consider the ATSAM4S2AA series if a smaller 48-pin package suffices for the design constraints.
Part Context
This component belongs to the SAM4S family of Flash microcontrollers based on the ARM Cortex-M4 architecture. The series offers scalable memory options ranging from 128 KB to 2 MB of Flash. It is designed for applications demanding high performance and low power consumption in a compact footprint.
Replacement Considerations
Consult the official SAM4S Series Datasheet for verified pin-compatible alternatives within the same family. Cross-reference part numbers like ATSAM4S2BA-AU for tray packaging variants if reel availability is critical.
