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. 6 SAM4E-EK Block Diagram SAM4E-EK Evaluation Kit [USER GUIDE] 6 Atmel-42067C-SAM4E-EK_UserGuide_022016 4.2 Features List 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 2.8 inch TFT color LCD display with touch panel and backlight UART port with RS232 driver USART port with RS232 driver multiplexed with RS485 function with driver CAN port with driver Mono/stereo headphone jack output One Ethernet physical transceiver layer with RJ45 connector SD/MMC interface Reset button: NRST User buttons: WAKU, TAMP, Scroll-up, and Scroll-down QTouch® buttons: Left, Right, and Slider Full Speed USB device port JTAG/ICE port On-board power regulation Three user LEDs Power LED BNC connector for ADC input BNC connector for DAC output User potentiometer connected to the ADC input ZigBee® connector PIO connection interfaces (PIOA, PIOC and PIOD with 32-bit, PIOB with 16-bit, and PIOE with 6bit) 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. The SAM4E-EK board is equipped with one NAND Flash MT29F2G08ABAEA on the EBI. This can change to other type of flash by setting the Static Memory Controller. SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 7 7 Figure 4-2. NAND-Flash NCS0 chip select signal is used for NAND Flash chip selection. Furthermore, a dedicated jumper can disconnect it from the on-board memories, thereby letting NCS0 free for other custom purposes. 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 3 to 20MHz Crystal Oscillator, which can be bypassed (12MHz needed in case of USB) A factory programmed fast internal RC Oscillator. Three output frequencies can be selected: 4 (default value), 8, or 12MHz. A 80 to 240MHz PLL (PLLB) providing a clock for the USB Full Speed Controller An 80 to 240MHz programmable PLL (PLLA), capable to provide the clock MCK to the processor and to the peripherals. The input frequency of PLLA is from 3 to 32MHz. The SAM4E-EK board is equipped with one 12MHz crystal, optional Piezoelectric Ceramic Resonator 12MHz (Murata ref. CSTCE12M0G15L99-R0), one 32.768Hz crystal and an external clock input connector. 8 SAM4E-EK Evaluation Kit [USER GUIDE] 8 Atmel-42067C-SAM4E-EK_UserGuide_022016 Figure 4-3. 4.3.4 External Clock Source Reset Circuitry On-board NRST button SW1 provides an external reset control of the SAM4E16. The NRST pin is bidirectional. It is handled by the on-chip reset controller. It can be driven low to provide a reset signal out to the external components. Conversely, it can be asserted low from the outside to reset the microcontroller core and the peripherals. The NRST pin integrates a permanent pull-up resistor of 100kΩ to VDDIO. On the SAM4E-EK board, the NRST signal is connected to the LCD module and JTAG port. Note: 4.3.5 At power-on, the NRST signal is asserted with default duration of two clock cycles. This duration may not be sufficient to correctly reset any other system or board devices connected to the signal. First, in your custom application, you need to check for these devices’ datasheets about reset duration requirements. Then, you need to set an appropriate configuration in the NRST Manager. This is done through the ERSTL field in the RSTC_MR register. The NRST duration is thereby configurable between 60μs and 2s, whether it is subsequently activated by a software reset or a user reset. Refer to the SAM4E16 datasheet for in-depth information. Power Supply and Management The Atmel SAM4E-EK board is supplied with an external 5V DC block through input J8. It is protected by a PolyZen diode (U3) and an LC combinatory filter (U4). The PolyZen is used in the event of an incorrect power supply connection. The adjustable LDO regulator U5 is used for the 3.3V rail main supply. It powers all the 3.3V components on the board. SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 9 9 Figure 4-4. Power Block The SAM4E16 product has different types of power supply pins: VDDIN pin: Power for the internal voltage regulator, ADC, DAC, and analog comparator power supplies. The voltage ranges from 1.6 to 3.6V. VDDIO pins: Power for the Peripherals I/O lines. The voltage ranges from 1.62 to 3.6V. VDDOUT pin: Output of the internal voltage regulator. VDDCORE pins: Power for the core, including the processor, embedded memories, and peripherals. The voltage ranges from 1.08 to 1.32V. VDDPLL pin: Power for the PLL A, PLL B and 12MHz oscillator. The voltage ranges from 1.08 to 1.32V. Note: 10 VDDPLL should be decoupled and filtered from VDDCORE. SAM4E-EK Evaluation Kit [USER GUIDE] 1 Atmel-42067C-SAM4E-EK_UserGuide_022016 0 4.3.6 UART The Universal Asynchronous Receiver Transmitter (UART) 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 U10 and brought to the DB9 male connector J20. Figure 4-5. 4.3.7 UART USART The Universal Synchronous/Asynchronous Receiver Transmitter (USART) provides one full duplex universal synchronous/asynchronous serial link. The data frame format is extensively configurable (data length, parity, and number of stop bits) to support a broad range of serial communication standards. The USART is also associated with PDC channels for TX/RX data access. To avoid any electrical conflict, the RS232 and RS485 transceiver are isolated from the receiving line PA21. Chose RS485 channel: Close 1-2 pins on J18 and set PA23 to high level Chose RS232 channel: Close 2-3 pins on J18 and set PA23 to low level SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 11 1 1 Figure 4-6. 4.3.8 USART RS485 As noticed above the USART1 is shared with the RS485 port, connected to the transceiver U9 and output to the 3-point connector J16. The design includes selectable jumpers for RS485 bus termination resistors selection (J15, J17, and J19). Figure 4-7. 12 RS485 SAM4E-EK Evaluation Kit [USER GUIDE] 1 Atmel-42067C-SAM4E-EK_UserGuide_022016 2 4.3.9 Ethernet MAC 10/100 (EMAC) The EMAC module implements a 10/100 Ethernet MAC compatible with the IEEE ® 802.3 standard using an address checker, statistics and control registers, receive and transmit blocks, and a DMA interface. The Atmel SAM4E-EK is equipped with a MICREL KSZ8081MNX 10/100 Mbps Fast Ethernet Physical Layer transceiver. It contains the entire physical layer functions of 100BASE-TX as defined by IEEE 802.3u. The Ethernet interface provides MII for 100Base-TX or 10Base-TX. The MII interfaces are capable of both 10Mb/s and 100Mb/s data rates as described in the IEEE 802.3u standard. The Ethernet interface integrates an RJ45 connector with an embedded transformer, and two status LEDs. Figure 4-8. Ethernet Block 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. SAM4E-EK connects the CAN0 and CAN1 bus to the CAN transceiver SN65HVD234 (U15 and U17). The extension connector (J41 and J44) type is RJ12 female socket. SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 13 1 3 Figure 4-9. CAN Block 4.3.11 Display Interface The SAM4E-EK carries a TFT transmissive LCD module with touch panel, FTM280C34D. Its integrated driver IC is ILI9325. The LCD display area is 2.8 inches diagonally measured, with a native resolution of 240 x 320 dots. 4.3.11.1 LCD Module The LCD module gets reset from the NRST signal. As explained, this NRST is shared with the JTAG port and the push-button SW1. The LCD chip select signal is connected to NCS1; the jumper J11 can disconnect it so that this PIO line is available for other custom usage. The SAM4E16 communicates with the LCD through PIOC where an 8-bit parallel “8080-like” protocol data bus has to be implemented in software. 14 SAM4E-EK Evaluation Kit [USER GUIDE] 1 Atmel-42067C-SAM4E-EK_UserGuide_022016 4 Figure 4-10. LCD Block 4.3.11.2 Backlight Control The LCD backlight is made of four integrated white chip-LEDs arranged in parallel. These are driven by an AAT3155 charge pump, U7. The AAT3155 is controlled by PC13; the 0Ω resistor R37 is mounted in series on this line, which permits to use it for other custom purposes. In that case, the pull-up resistor R35 maintains the charge pump permanently enabled by default. On the anode drive line, a 0Ω resistor R25 is implemented in series for an optional current limitation. Figure 4-11. Backlight Control SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 15 1 5 4.3.12 Touch Screen Interface The LCD module integrates a 4-wire touch panel controlled by U6 (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. Two interrupt signals are connected and provide events information back to the microcontroller: PenIrq and Busy. Note: PenIrq (PA16) is shared with ZigBee signal ZIGB_MISC. Busy (PA17) is shared with ZigBee signal ZIGB_IRQ. Therefore, if using a ZigBee interface in concurrence with the Touch Screen controller, take care not to have both drivers enabled at the same time on either PA16 or PA17. Figure 4-12. Touch Panel Control 4.3.13 JTAG/ICE A standard 20-pin JTAG/ICE connector is implemented on the Atmel SAM4E-EK for the connection of a compatible ARM JTAG emulator interface, such as the SAM-ICE™ from Segger. Note that the NRST signal is connected to SW1 system button and is also used to reset the LCD module. The 0Ω resistor R75 may be removed in order to isolate the JTAG port from this system reset signal. 16 SAM4E-EK Evaluation Kit [USER GUIDE] 1 Atmel-42067C-SAM4E-EK_UserGuide_022016 6 Figure 4-13. JTAG Interface 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. Headphone Output Using a readily available 1/8-in. (3.5mm) stereo headphone jack, the control switch (pin4 and pin5 in J24) is closed when no plug is inserted. When closed, a 100kΩ/1kΩ divider pulls the ST/MN input low. When a jack plug is inserted, the 1kΩ resistor is disconnected and the ST/MN input is pulled high. The mono speaker (J22 connector) is also physically disconnected from the RO/MO+ output so that no sound is heard from the speaker while the headphones are inserted. When works as stereo mode make sure J25, J27, and J26 are disconnected. SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 17 1 7 4.3.15 USB Device The SAM4E16 UDP port is compliant with the Universal Serial Bus (USB) rev 2.0 Full Speed device specification. J34 is a micro B-type receptacle for USB device. Both 27Ω resistors R96 and R97 build up 90Ω differential impedance together with the (embedded) 6Ω output impedance of the SAM4E16 full speed channel drivers. R93 and R94 build up a divider bridge from VBUS +5V to implement plug-in detection (5V level gets lowered to a PIO compatible 3.3V level) through PC21. Figure 4-15. USB 4.3.16 Analog Interface 4.3.16.1 Analog Reference The 3.0V voltage reference is based on a LM4040 (Precision Micropower Shunt Voltage Reference). This ADVREF level can be set as 3.0V or 3.3V via the jumper J2. Figure 4-16. 18 Analog VREF SAM4E-EK Evaluation Kit [USER GUIDE] 1 Atmel-42067C-SAM4E-EK_UserGuide_022016 8 4.3.16.2 Analog Input The BNC connector CM1 is connected to the AEF0_AD4 or AFE1_AD0 (selected by JP40) as a single external analog input The BNC connectors CM3, CM4 are connected to AFE0_AD10 and AFE0_AD11 as a differential external analog input. A low pass filter is optional by close 1-2 pins of J32, J33, J36, and J37. Each BNC input has an on-board 50Ω resistor termination that can be applied by closing jumper J30, J35 or J38 A 10kΩ potentiometer (VR1) is also connected to the AFE0_AD5 implement an easy access to ADC programming and debugging (or implement an analog user control like display brightness, volume, etc.) Figure 4-17. ADC/AFE Input SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 19 1 9 4.3.16.3 Analog Output The BNC connector CM2 is connected to the DAC port PB14 and provides an external analog output. An on-board 50Ω resistor termination can be enabled by closing jumper J31. A filter can be implemented on this output channel by replacing R88 and C71 with appropriate resistor and capacitor values, depending on the application requirements. Figure 4-18. DAC Output 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. 20 QT_Slider SAM4E-EK Evaluation Kit [USER GUIDE] 2 Atmel-42067C-SAM4E-EK_UserGuide_022016 0 4.3.18 LEDs There are three LEDs on the SAM4E-EK board: A blue LED (D2), amber/orange LED (D3) and a green LED (D4), which are user defined and controlled by the GPIO A red LED (D5), which is a power LED indicating that the 3.3V power rail is active. It is also controlled by the GPIO and can be treated as a user LED as well. The only difference with the two others is that it is controlled through a MOS transistor. By default, the PIO line is disabled; a pull-up resistor controls the MOS to light the LED when the power is ON. Figure 4-20. LEDs 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. SD Card SAM4E-EK Evaluation Kit [USER GUIDE] Atmel-42067C-SAM4E-EK_UserGuide_022016 21 2 1 4.3.20 ZigBee The SAM4E-EK has a 10-pin male connector for the RZ600 ZigBee module. Note: 0Ω resistors have been implemented in series with the PIO lines that are used elsewhere in the design, thereby enabling their individual disconnection, should a conflict occur in your application. Figure 4-22. ZigBee Interface 4.3.21 PIO Expansion The SAM4E-EK product features three PIO controllers, PIOA, PIOB, PIOC, and PIOD, which are multiplexed with the I/O lines of the embedded peripherals. Each PIO Controller controls up to 32 lines (15 for PIOB and 6 for PIOE). Expansion ports J51, J52, J53, and J54 provide PIO lines access for customer usage. 22 SAM4E-EK Evaluation Kit [USER GUIDE] 2 Atmel-42067C-SAM4E-EK_UserGuide_022016 2 Figure 4-23.
