ATSAM4S4CA-AN

Overview

The ATSAM4S4CA-AN is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at 120 MHz. It features 256 KB of Flash memory and 64 KB of SRAM within a 100-pin LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and operates within an industrial temperature range of -40°C to 105°C. Key peripherals include full-speed USB, SDIO/SD/MMC interfaces, multiple SPI and I2C controllers, and a rich analog set comprising 16-channel 12-bit ADCs and 2-channel 12-bit DACs.

Feature Summary

Integrates ARM Cortex-M4 processor with optional cache memory for high-performance execution.
Provides hardware code protection including IP protection and secure chip erase capabilities.
Supports Microchip QTouch capacitive touch technology for intuitive user interfaces.
Features multi-layer bus matrix and DMA channels for efficient data handling.

Applications

Industrial control systems
Medical devices
Consumer goods and toys
Metering equipment

Procurement Notes

Verify the specific ordering suffix 'AN' confirms the 100-pin LQFP package and extended temperature range (-40°C to 105°C) as documented in the datasheet. Ensure compatibility with existing board layouts designed for this package type. Confirm that the internal oscillator configuration meets system timing requirements without external components.

Selection Notes

Select this component when pin-to-pin migration from SAM4N, SAM3S, or SAM7S families is required. Choose the ATSAM4S4CA-AN if 256 KB Flash and 64 KB RAM are sufficient for application logic. Consider the 100-pin LQFP form factor for prototyping ease compared to BGA options. Verify peripheral availability matches interface needs such as USB and SDIO.

Part Context

This part belongs to the SAM4S series of Microchip microcontrollers, which are designed for scalable performance and power efficiency. The series integrates up to 2 MB of Flash and 160 KB of SRAM across various packages. The ATSAM4S4CA-AN represents a mid-range density option within this portfolio, balancing processing power with memory capacity for general-purpose embedded applications.
