Overview
The ATSAM4SD16BB-MN is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at a maximum frequency of 120MHz. It features 1MB (1M x 8) of Flash memory and 160KB of RAM. The device includes 11 channels of 12-bit ADC and 2 channels of 12-bit DAC. It supports interfaces including I2C, SPI, SSC, UART/USART, USB, and SD/MMC card storage. Powered by 1.62V to 3.6V, it operates between -40°C and 105°C in a 64-QFN package.
Feature Summary
- Integrates an ARM Cortex-M4 processor with hardware floating-point unit for efficient signal processing.
- Includes dedicated SD/MMC controller for direct mass storage interface without external logic.
- Provides full-speed USB device and host capabilities for data communication.
- Features multiple serial communication peripherals including USART, SPI, and I2C.
Applications
- Industrial control systems requiring robust peripheral integration
- USB-enabled data logging devices
- Consumer electronics with mass storage requirements
- Motor control applications utilizing hardware FPU
Procurement Notes
Verify the specific suffix 'MN' corresponds to the 64-QFN package and industrial temperature range during sourcing. Confirm RoHS compliance status as per current manufacturer documentation. Ensure ESD handling procedures are followed due to the exposed pad thermal design. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.
Selection Notes
Select this component when 1MB Flash and 160KB RAM are required alongside native SD/MMC and USB support. The 120MHz Cortex-M4 core suits applications needing moderate computational power. Compare against ATSAM4S variants if SD/MMC or specific RAM sizes differ from project needs. Verify voltage supply ranges match system power architecture.
Part Context
This part belongs to the Microchip SAM4S series, designed for high-performance embedded applications. The series utilizes the ARM Cortex-M4 architecture, balancing processing speed with power efficiency. It integrates extensive connectivity options suitable for complex IoT and industrial environments.
Replacement Considerations
ATSAM4SD16BA-AU: Different package (LQFP-100) and lower temperature range (-40°C to 85°C). ATSAM4S16CA-AU: Lacks SD/MMC controller and has different I/O count. ATSAM4SD32BA-MU: Higher Flash capacity (2MB) but similar peripheral set.
