2.2 Electrostatic warning The Atmel SAM4E-EK board is shipped in a protective anti-static bag. The board must not be subjected to high electrostatic potentials. A grounding strap or similar protective device should be worn when handling the board. Avoid touching the components or any other metallic element of the board.
3. Power up 3.1 Power up the board Unpack the board taking care to avoid electrostatic discharge. Unpack the power supply, select the right power plug adapter corresponding to that of your country, and insert it into the power supply. Connect the power supply DC connector to the board and plug the power supply to an AC power socket. The board LCD should light up and display a welcome page. Then click or touch the icons displayed on the screen and enjoy the demo. 3.
4. Board Description 4.1 Board overview This chapter introduces the Atmel SAM4E-EK Evaluation Kit design. It introduces system-level concepts, such as power distribution, memory, and interface assignments. The SAM4E-EK board is based on the integration of an ARM® Cortex™-M4 processor with on-board NAND Flash and a set of popular peripherals. It is designed to provide a high performance processor evaluation solution with high flexibility for various kinds of applications. Figure 4-1.
4.2 Features list The list of the main board components and interfaces: • • • • • • • • • • • • • • • • • • • • • • • • SAM4E16 chip BGA144 package with optional socket footprint 12MHz crystal 32.768kHz crystal Optional SMB connector for external system clock input NAND Flash 2.
4.3 Function blocks 4.3.1 Processor The Atmel SAM4E-EK is equipped with a SAM4E16 device in BGA144 package. 4.3.2 Memory The SAM4E16 chip embeds: • • • 1024kB of embedded Flash 128kB of embedded SRAM 16kB of ROM with embedded boot loader routines (UART, USB) and In-Application Programming functions (IAP) routines The SAM4E16 features an External Bus Interface (EBI) that permits interfacing to a broad range of external memories and virtually to any parallel peripheral.
4.3.3 Clock circuitry The clock generator of a SAM4E16 microcontroller is composed of: • • • A low-power 32.768Hz Slow Clock Oscillator with bypass mode • • A 80 to 240MHz PLL (PLLB) providing a clock for the USB Full Speed Controller A 3 to 20MHz Crystal Oscillator, which can be bypassed (12MHz needed in case of USB) A factory programmed fast internal RC Oscillator.
Power supply and management The Atmel SAM4E-EK board is supplied with an external 5V DC block through input J1. It is protected by a PolyZen diode (MN2) and an LC combinatory filter (MN3). The PolyZen is used in the event of an incorrect power supply connection. The adjustable LDO regulator MN4 is used for the 3.3V rail main supply. It powers all the 3.3V components on the board. Figure 4-4. Power block. J1 MN2 Power Jack 2.
4.3.6 UART The Universal Asynchronous Receiver Transmitter features a two-pin UART that can be used for communication and trace purposes. It offers an ideal channel for in-situ programming solutions. This UART is associated with two PDC channels to reduce the processor time on packet handling. This two-pin UART (TXD and RXD only) is buffered through an RS232 Transceiver MN6 and brought to the DB9 male connector J7. Figure 4-5. UART.
4.3.8 RS485 As noticed above the USART1 is shared with the RS485 port, connected to the transceiver MN6 and output to the 3point connector J6. The design includes selectable jumpers for RS485 bus termination resistors selection (JP10, JP12, and JP13). Figure 4-7. RS485.
4.3.10 CAN The CAN controller provides all the features required to implement the serial communication protocol CAN defined by Robert Bosch GmbH, the CAN specification as referred to by ISO/11898A (2.0 Part A and 2.0 Part B) for high speeds and ISO/11519-2 for low speeds. The CAN Controller is able to handle all types of frames (Data, Remote, Error and Overload) and achieves a bit rate of 1Mbit/sec. The Atmel SAM4E has two CAN Controller with eight Mailboxes.

4.3.12 Touch screen interface The LCD module integrates a 4-wire touch panel controlled by MN16 (ADS7843) which is a slave device on the SAM4E16 SPI bus. The controller sends back the measurement information about the X and Y positions as a pressure is applied to the touch panel. The touch panel can be used with either a stylus or a finger. The ADS7843 touch panel controller connects to the SPI interface via the NPCS0 control signal.
4.3.14 Audio Interface The Atmel SAM4E-EK evaluation kit supports mono/stereo audio driven by a TPA0223 audio amplifier connected to two DAC channels of the microcontroller. The TPA0223 is a 2W mono Bridge-Tied-Load (BTL) amplifier designed to drive speakers with as low as 4Ω impedance. The amplifier can be reconfigured on the fly to drive two stereo Single-Ended (SE) signals into head phones. Figure 4-14.

4.3.17 QTouch elements QTouch keys consist in a series of sensors formed by the association of a copper area and the capacitive effect of human fingers approaching it. Keys The Atmel SAM4E-EK implements two individual capacitive touch keys (RIGHT, LEFT). Slider A group of channels forms a Slider. A Slider is composed of eight channels for a QTouch acquisition method. Such a sensor is used to detect a linear finger displacement on a sensitive area. A typical implementation is volume control. Figure 4-19.
4.3.19 SD/MMC card The Atmel SAM4E-EK has a high-speed 4-bit multimedia MMC interface, which is connected to a 4-bit SD/MMC micro card slot featuring a card detection switch. Figure 4-21.
