ATSAM4S-EK Visão geral
A development kit is a printed circuit board assembled by the MCU vendor that exposes the most important peripherals (GPIO, communication buses, memory, display, and power) on standard connectors, allowing engineers to bring up firmware, prototype peripherals, and benchmark performance without designing production hardware. Evaluation kits like the ATSAM4S-EK sit in the broader embedded hardware hierarchy of evaluation board -> development board -> prototype -> production design, and are essential for time-to-market-sensitive product development.
Key features include SAM4S16 compatibility with up to 1024 KB Flash and 128 KB SRAM, support for both SAM4S8 (smaller Flash option) and SAM4S16 (larger Flash option) via a single kit, an integrated TFT LCD display for HMI prototyping, and full-speed USB Device port connectivity. The kit also provides an Ethernet physical interface, an SD card slot for storage expansion, and multiple Atmel QTouch-capable touch buttons, wheels and sliders for capacitive touch evaluation. Atmel Studio 6 IDE and the Atmel Software Framework are fully supported, shortening the learning curve for engineers migrating from legacy AVR or ARM7 designs.
The ATSAM4S-EK uses the SAM4S series architecture that is pin-to-pin and software compatible with the SAM3S ARM Cortex-M3 family and migration-friendly to the SAM4N family, giving developers an upgrade path without reworking hardware. The kit exposes the Cortex-M4 single-precision floating-point unit and the full SAM4S peripheral set including HS USB, EMAC, CAN, and the peripheral event system.
Typical applications include industrial HMI prototypes with TFT touch, motor control evaluation, USB device and host stack bring-up, Ethernet-connected IoT sensor nodes, and consumer electronics proof-of-concept designs. The kit is widely used by engineers transitioning from Atmel AVR or ARM7 designs to the Cortex-M4 architecture.
When planning a project, evaluate the ATSAM4S-EK alongside the ATSAM4S-EK2 (which targets the SAM4SD32 with higher Flash density) and the SAM D family (Cortex-M0+) Xplained Pro kits to confirm the right MCU footprint. For volume production, migrate from the ATSAM4S-EK prototype to a discrete SAM4S8C/16C MCU on a custom PCB while preserving the kit's reference peripheral layouts.

Aplicações típicas
ATSAM4S-EK é adequado para 7 aplicaçãos: Industrial HMI Prototype, USB Device Peripheral Bring-Up, Ethernet-Connected IoT Sensor Node, Motor Control Evaluation, Capacitive Touch User Interface, Firmware Migration from AVR/ARM7, Consumer Electronics Proof-of-Concept.
Industrial HMI Prototype
The ATSAM4S-EK's integrated TFT LCD and Atmel QTouch capacitive touch support make it ideal for industrial human-machine interface (HMI) prototypes. The SAM4S16's Cortex-M4 core at 120 MHz can drive graphical menus, while the on-board Ethernet port enables Modbus TCP or PROFINET-style communications with industrial controllers. Unlike lower-end kits, this board exposes enough GPIO and peripheral bandwidth to mimic real production HMIs.
Recomendado
USB Device Peripheral Bring-Up
The ATSAM4S-EK's full-speed USB Device port and the SAM4S peripheral set make it well suited for USB device stack bring-up, including HID, CDC, and vendor-class devices. Engineers can prototype USB peripherals without building a custom PCB, then migrate to the bare ATSAM4S16CB-CFN for production. The Cortex-M4's deterministic interrupt latency is ideal for USB isochronous endpoints.
Recomendado
Ethernet-Connected IoT Sensor Node
The ATSAM4S-EK integrates an Ethernet physical interface and runs the SAM4S Cortex-M4 at 120 MHz, giving developers enough headroom to evaluate Ethernet-connected sensor nodes with TCP/IP stacks, MQTT, or HTTP servers. The on-board NAND Flash provides space for logging buffers, and the SD card slot adds removable storage. Unlike Wi-Fi kits, the wired Ethernet simplifies deterministic latency testing.
Recomendado
Motor Control Evaluation
The SAM4S Cortex-M4 core on the ATSAM4S-EK integrates a single-precision FPU that accelerates field-oriented control (FOC) loop computation, making the kit suitable for BLDC and PMSM motor control evaluation. Engineers can connect the kit's PWM outputs and ADC inputs to motor driver boards via GPIO headers, then migrate to ATSAM4S16CB-CFN for production motor drives.
Recomendado
Capacitive Touch User Interface
The ATSAM4S-EK supports the Atmel QTouch library for capacitive touch buttons, wheels, and sliders, making it ideal for evaluating touch-based user interfaces on appliances, consumer electronics, and industrial control panels. The library integrates PTC (Peripheral Touch Controller) hardware, and engineers can prototype touch layouts on the kit's exposed touch headers before committing to a custom PCB layout.
Recomendado
Firmware Migration from AVR/ARM7
Engineers migrating from legacy Atmel AVR or ARM7 designs to a Cortex-M4 architecture can use the ATSAM4S-EK as a benchmark platform. The SAM4S family offers pin-to-pin and software compatibility with SAM3S ARM Cortex-M3 devices, and the Atmel Software Framework (ASF) provides familiar drivers. The kit's Atmel Studio 6 IDE integration shortens the migration learning curve.
Recomendado
Consumer Electronics Proof-of-Concept
The ATSAM4S-EK's combination of TFT display, USB, Ethernet, and SD card makes it a strong proof-of-concept platform for consumer electronics such as smart appliances, connected toys, and home automation hubs. The Cortex-M4's 120 MHz clock plus FPU allows smooth graphics rendering, while the kit's audio and peripheral headers support speaker and microphone integration.

Notas de projeto
The ATSAM4S-EK operates at industrial temperature ranges (-40C to +85C) for the SAM4S MCU, but the kit itself is intended for laboratory and prototyping use only. Production designs should use the bare SAM4S8C/16C MCU on a custom PCB with proper thermal vias under the LQFP-100 exposed pad. Estimated: at 120 MHz with all peripherals active, the SAM4S16 typically dissipates under 200 mW, well within the LQFP-100 thermal envelope.
When migrating from the ATSAM4S-EK to a custom PCB, replicate the kit's decoupling network: place a 100 nF X7R ceramic capacitor on each VDD pin within 3 mm of the pin, and a single 4.7 uF bulk capacitor near the voltage regulator output. According to Microchip's SAM4S hardware design guide, missing the bulk capacitor is the most common cause of brown-out resets on production SAM4S boards.
Do not assume SAM4S firmware compiled for the ATSAM4S-EK kit will run unchanged on a bare ATSAM4S4AB-AN prototype - the smaller SAM4S4 has only 48 KB SRAM versus 128 KB on the SAM4S16, and large buffer allocations can fail to link. Profile memory usage on the kit first, then plan production MCU selection accordingly. Also note that the Atmel Software Framework (ASF) has been superseded by Microchip's MPLAB Harmony; legacy ASF projects may require migration.
Route the SAM4S Cortex-M4 crystal traces (12 MHz main XIN/XOUT, 32.768 kHz RTC XIN32/XOUT32) as short as possible, keep them away from switching signals, and guard them with a ground pour on both sides. According to the SAM4S datasheet (Atmel-11100), incorrect crystal layout is the most common cause of USB Device certification failures on SAM4S designs.
