Chapter 2.Purpose This RSK Application Board is an evaluation tool for using Renesas microcontrollers with Ethernet and USB interfaces. It is used in conjunction with the RSK for the microcontroller to be evaluated. Features include: • Mounting connections to allow RSK to be added to top of board. • Interface to standard RSK ‘Application Interface’ connectors. • Interface to Memory Expansion connectors. • Power connector for +5V (reverse polarity protected), with on-board regulated 3.
Chapter 3.Board Layout 3.1.Component References The following diagram shows the component references for the board.
3.2.Board Component functions The following diagram the shows the functions of the components on the board.
3.3.Board Dimensions The following diagram gives the board dimensions and connector positions. All through hole connectors are on a common 0.1” grid for easy interfacing.
Chapter 4.User Circuitry 4.1.Fitting the Target RSK to the RSK application board The board is supplied with 2x 24 way sockets, 2x 26 way sockets and 1 x 50 way socket. These should be soldered on the underside of the host RSK in JA1, JA2, JA5, JA6 and JA3 positions. The RSK should be plugged into the equivalent connectors on the RSK LCD application board. A separate application note is available to explain how to configure the host RSK to enable it to connect to this application board.
5ns A[7:1] 5ns 35ns CSn,WRn 10ns 5ns Valid Data Figure 4-2: Ethernet controller write timing The Ethernet controller can drive two interrupts. IRQ0 is the IRQ from the Ethernet controller. IRQ2 is the PME output from the Ethernet controller. PME interrupts can be enabled on the IRQ pin, so this can be disabled for host RSKs with fewer interrupt lines, if the PME interrupt is required. Both interrupts are pulled high to 3.3V by 1K resistors. 4.3.
5ns A[17:1] 5ns 40ns CSn,RDn 0ns 35ns Valid Data Figure 4-3: USB controller read timing 5ns A[17:1] 5ns 20ns CSn,WRn 8ns 5ns Valid Data Figure 4-4: USB controller write timing The ISP1761 controller can drive two interrupts. IRQ1 is the HC_IRQ from the ISP1761 controller. IRQ3 is the DC_IRQ output from the ISP1761 controller. DC_IRQ interrupts can be enabled on the HC_IRQ pin, so this can be disabled for host RSKs with fewer interrupt lines, if the DC_IRQ interrupt is required.
4.4.SRAM The board is provided with 512 kilobytes of static RAM arranged as 256k x 16 bit words. This RAM is byte addressable, provided the host RSK supports this. The chip select used for the RAM is CS3 which is on JA3 pin 45. Please note the timing. This will require programming the bus controller for the Host RSK.
4.5.Option Links Table 4-1 below describes the function of the option links contained on this CPU board. The default configuration is indicated by BOLD text.
Chapter 5.Headers 5.1.Application Headers This information is supplied for reference. Only pins marked are connected on this board. These connections are not level translated. Table 5-1 and Table 5-2 below show the standard application header connections.
