ATSAM4S8CA-AN

Overview

The ATSAM4S8CA-AN is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at 120 MHz. It features 512 KB of Flash memory and 128 KB of SRAM. The device includes an external bus interface, FS USB Device, HS SDIO/SD/MMC, three SPIs, two I2Cs, two USARTs, two UARTs, sixteen 12-bit ADC channels, and two 12-bit DACs. It supports up to 79 I/Os and operates within a temperature range of -40°C to 105°C.

Feature Summary

Integrated ARM Cortex-M4 processor with 2 KB cache for high performance
Hardware code protection including IP access prevention and CRC checks
Native support for Microchip QTouch capacitive touch technology
Multi-layer AHB matrix with 21-channel DMA for high data rate communication

Applications

Consumer goods and toys
Industrial control systems
Metering devices
Medical equipment
Test and measurement instruments

Procurement Notes

Verify the specific ordering suffix 'N' indicates the extended industrial temperature range (-40°C to 105°C) as documented in the datasheet. Confirm package type compatibility during procurement. Ensure the component matches the exact part number ATSAM4S8CA-AN to guarantee correct memory density and peripheral configuration.

Selection Notes

Select this model for applications requiring 512 KB Flash and 128 KB SRAM with an industrial temperature rating. It offers pin-to-pin compatibility with SAM4N, SAM3S, SAM3N, and SAM7S devices for migration purposes. Consider the integrated QTouch support if capacitive sensing is required without additional hardware.

Part Context

This component belongs to the SAM4S series of 32-bit MCUs from Microchip Technology. The series provides scalable performance with memory densities up to 2 MB Flash and 160 KB SRAM. The ATSAM4S8CA-AN specifically utilizes the 100-pin LQFP package variant designated by the 'A' suffix in the base part number structure.
