CONNECTCORE 9U Overview The CONNECTCORE 9U microcontroller module is a member of the UNC (Universal Network Controller) family. The CONNECTCORE 9U module is based on Atmel’s AT91RM9200 ARM9 microcontroller running at 180 MHz. It’s housed in an industry-standard DIL 48 package, making it extremely easy and costeffective to integrate into designs which require Ethernet and USB connectivity. The CONNECTCORE 9U has the same form factor (63 x 19 mm) as the CONNECTCORE 7U. The pin compatibility allows CONNECTCORE 7U users to easily migrate to the ARM9 technology, offering higher performance. 2. ATMEL AT91RM9200 The AT91RM9200 is a complete system-on-chip built around the ARM920T ARM Thumb processor. It incorporates a rich set of system and application peripherals and standard interfaces in order to provide a single-chip solution for a wide range of compute-intensive applications that require maximum functionality at minimum power consumption at lowest cost. 4 UNC90_DSc.doc UNC90 - Datasheet 2.1.

Port pin mapping The mapping of the PORT pins available externally on the CONNECTCORE 9U module are shown in the table below : Signal CONNECTCORE 7U PORTA0 PORTA1 PORTA2 PORTA3 PORTA4 PORTA5 PORTA6 PORTA7 PORTC0 PORTC1 PORTC2 PORTC3 PORTC4 12 Signal CONNECTCORE 9U PB23 DCD1# / none PB0 TF0 / RTS3 PB24 CTS1# / none PB25 DSR1# / EF100 PB21 RXD1 / none PB3 RD0 / MCDA1 PB1 TK0 / CTS3# PB26 RTS1# / none PD25 DTR1# / TPK13 PB27 PCK0 PB20 TXD1 / none PB2 TD0 / SCK3 PB6 TF1 / TIOA3 PB29 IRQ0 / none PA27 MCCK / TCLK3 PA30 DRXD / CTS2# PB28 FIQ PA25 TWD / IRQ2 PA22 RXD2 / TIOB2 PB9 RD1 / TIOB4 PA2 SPCK / IRQ4 PA24 SCK2 / PCK1, PB7 TK1 / TIOB3 Serial SPI, NMSI DCD1# TF0 Special Functions Hardwired CTS1# DSR1# RXD1 RD0 RI1# (1) RTS1# TK0 DTR1# TXD1 TD0 TF1 CTS2# RXD2 IRQ0 FIQ RD1 IRQ2 IRQ4 TWD (2) RESET_OUT# / TK1 UNC90_DSc.doc UNC90 - Datasheet Signal CONNECTCORE 7U PORTC5 PORTC6 PORTC7 Signal CONNECTCORE 9U PA31 DTXD / RTS2# PA26 TWCK / IRQ1 PA23 TXD2 / IRQ3 PB8 TD1 / TIOA4 Serial SPI, NMSI Special Functions Hardwired IRQ1 TWCK (2) RTS2# TXD2 TD1 Notes : (1) - The signal RI1 (from USART1) is shared with the ECOL (collision detect) MII signal and it’s not accessible on another pin. The ring indicator function must be made through an IRQ sensitive port pin. The port pin used is PA2, this pin has an IRQ feature. (2) - TWD and TWCK signals come from the Two Wire Unit (TWI Unit) and are used for I2C interface. Only USART1 has DSR, DTR, DCD and RI signals – the other one is a standard USART (only TXD, RXD, CTS and RTS signals). Signals DTXD and DRXD are accessible on the CONNECTCORE 9U socket - this allow us to have access to the Debug Unit (DBGU). DTXD is accessible on PORTC5 and DRXD is accessible on PORTC1. The port pins can be used as interrupt pins, but there is a double condition. Firstly, the PIO interrupts are not level sensitive, but change sensitive. Secondly, these IRQ can not be used in power save modus (an input change detection is possible only by comparing two successive samplings of the input of the I/O line, that’s why the PIO controller clock must be enabled or this clock signal can be stopped during power save modus). The input change interrupt is available, regardless of the configuration of the I/O line, i.e. configured as an input only, controlled by the PIO controller or assigned to a peripheral function. 3.5.

Reset Pin On the CONNECTCORE 7U, the reset pin was a bi-directional signal allowing to directly connect a reset button outside the module. Since the power on reset needs to way until the 32 kHz Oscillator is stabilized (start-up time of 900ms), the power on reset signal on the CONNECTCORE 9U must be quite long and that’s why a open-drain reset controller has been used (this type of controller have longer reset time). This choice implies that when a reset signal comes from outside, it needs to be debounced externally and an additional reset controller should be added on the baseboard. 3.7. USB If the USB signals aren’t used externally on the base board, it’s recommended to put pull-down resistors on the signals. A typical value for this pull-down resistors is 15k. 3.8. EEPROM mapping The system needs a storage for configuration data, such as the MAC address for the Ethernet Controller. On the module is a 8Kbytes EEPROM with an I²C interface for this purposes. Address 0x0000 – 0x007F 0x0080 – 0x00FF 0x0100 – 0x08FF 0x0900 – 0x0CFF 0x0D00 – 0x1FFF 14 Description Production Area Reserved Area U-Boot environment Linux environment User space UNC90_DSc.doc UNC90 - Datasheet 3.9. Software 3.9.5. Bootloader The CONNECTCORE 9U boots with the universal bootloader U-Boot. U-Boot is an open-source cross-platform boot loader that provides out-of-the-box support for hundreds of embedded boards and a wide variety of CPUs including PowerPC, ARM, XScale, MIPS, Coldfire, NIOS, Microblaze and x86. U-Boot is capable of downloading the kernel and the rootfs by Ethernet. Therefore no flash programming is needed to test a new kernel. After power-up or reset the processor loads the U-Boot boot loader. This is performed in different steps.  The AT91RM9200 microcontroller executes a primary bootstrap that configures the interrupt and exception vectors, the clocks and the SDRAM, then decompresses the U-Boot code from Flash to RAM, and finally passes the execution control to the U-Boot.  The U-Boot configures the Ethernet PHY, the Flash memory, the serial console and loads the settings stored as environment variables in the EEPROM.  Then after a timeout (programmable) U-Boot executes the script (list of commands separated by semi-colons) contained in environment variable bootcmd. The user can stop the autoboot by sending a character to the serial port (pressing a key from the serial console connected to the target). If stopped, U-Boot displays a command line console. U-Boot uses the first 128k address range of the flash memory to store the bootloader. Address 0x1002 0000 – 0x10FF FFFF 0x1001 0000 – 0x1001 FFFF 0x1000 0000 – 0x1000 FFFF UNC90_DSc.doc Area 15.875Mbytes Flash available 64 Kbytes U-Boot image 64 Kbytes boot.bin image 15 UNC90 - Datasheet The preliminary bootloader (boot.bin) is in charge of making the very early initialization of the CPU. It also loads the u-boot image from flash to RAM and once it is in RAM runs from there. 3.9.6.
