ATSAM4S2BB-UUR

Overview

The ATSAM4S2BB-UUR is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at speeds up to 120MHz. It integrates 128KB of Flash memory and 64KB of SRAM within a 64-WLCSP package. The device supports a supply voltage range of 1.62V to 3.6V and includes data converters comprising 16-channel 12-bit ADCs and 2-channel 12-bit DACs. Connectivity options include I2C, IrDA, Memory Card, SPI, SSC, UART/USART, and USB interfaces.

Feature Summary

Integrates an ARM Cortex-M4 processor for high-performance 32-bit processing capabilities
Includes mixed-signal peripherals with multiple 12-bit analog-to-digital and digital-to-analog converters
Supports diverse communication protocols including serial peripheral interface and universal asynchronous receiver-transmitter
Features internal oscillator types for simplified clocking requirements

Applications

Industrial control systems requiring robust communication interfaces
Consumer electronics utilizing low-voltage power supplies
Embedded applications needing integrated analog signal processing
Portable devices benefiting from compact wafer-level packaging

Procurement Notes

Verify the specific suffix UUR corresponds to the 64-WLCSP package configuration when sourcing components. Confirm that the manufacturer designation aligns with Microchip Technology specifications. Ensure compliance with environmental standards such as RoHS if required by your manufacturing process. Cross-reference the datasheet for any recent product change notifications regarding assembly locations or marking changes.

Selection Notes

Select this component when a balance of processing speed and analog connectivity is required in a small footprint. The 120MHz Cortex-M4 core suits applications needing efficient code execution. Consider the 1.62V minimum voltage for battery-operated designs. Evaluate the 16-channel ADC count against sensor input requirements before finalizing the design.

Part Context

This part belongs to the SAM4S series of microcontrollers from Microchip Technology. The series utilizes the ARM Cortex-M4 architecture to deliver performance suitable for complex embedded tasks. The ATSAM4S2BB variant specifically offers 128KB of program memory, distinguishing it from lower-capacity models in the same family while maintaining similar peripheral sets.
