DS89C450 Evaluation Kit Board Layout DETAILED DESCRIPTION The DS89C450 EV kit must be used with the DS89C430/DS89C450 ultra-high-speed flash microcontrollers IC data sheet and the Ultra-High-Speed Flash Microcontroller User’s Guide (www.maxim-ic.com/user_guides). A complete description of the bootstrap loader commands and functions is located in Section 15 of the Ultra-High-Speed Flash Microcontroller User’s Guide. The DS89C450 EV kit and all of its connectors are defined in the schematics provided in the accompanying documentation disk. However, a short description of the major components of the board follows. Power Supplies The EV kit accepts a DC input supply at J1. The supply should be a 6V to 9V DC supply, center post positive, with at least 300mA capacity. The exact DC input value of the supply is not important, as the on-board linear MAX1658 and MAX1659 regulators produce fixed 5V and 3.3V for use by the kit circuitry. While it is possible to supply up to 16V at J1 (the maximum input voltage of the MAX1658 and MAX1659), doing so results in a large amount of heat dissipation from the board. A small heatsink plane is provided on the backside of the board beneath the linear regulators, but this may be inadequate at input voltages above 9V. If U1 and U2 are hot, lower the DC input voltage at J1. Note that many unregulated DC wall plug-in supplies may provide an output level much higher than their labeled output value if they are lightly loaded. 3 of 13 DS89C450 Evaluation Kit Serial Ports Both serial ports of the DS89C450 (Serial Port 0 and Serial Port 1) are translated to RS-232 levels and brought out to DB9 connectors at J2 and J3. Serial Port 0 (J2) must always be used when communicating with the bootloader. Memory The external memory of the DS89C450 on this EV kit is designed to operate with the address and data bus multiplexed on P0 and P2. A 128kB x 8 SRAM is installed, which is accessed as both program and data memory by this multiplexed bus. Note that as the total memory space of the DS89C450 is only 64kB of program memory and 64K of data memory, port pin memory banking must be used to access the entire 128kB-memory space. CPLD The CPLD device on the EV kit board is preprogrammed to perform several functions.  Address latching of the low 8 bits of the external memory address from port P0.  Mapping together program and data memory.  Performing port pin memory banking (optional). The RTL code preprogrammed into the CPLD is as follows. module Eval(AD, nRD, ALE, nPSEN, CFG0, CFG1, SW_IN, P1, A, A16, A17, nOE, SW_OUT); input input input input input input input [7:0] AD; nRD; ALE; nPSEN; CFG0; CFG1; SW_IN; // // // // // // // inout [7:0] P1; // Port 1 from micro output [7:0] A; output A16; output A17; output nOE; output SW_OUT; reg // // // // // Multiplexed low-order address and data from micro Data memory read enable from micro Address latch enable from micro Program memory read enable from micro Configuration input zero (from DIP switch) Configuration input one (from DIP switch) Interrupt switch input (from pushbutton) Demultiplexed low-order address to RAM Address line to RAM Address line to RAM Output enable to RAM Interrupt switch output (to micro) [7:0] A; always @(negedge ALE) begin A Load Flash and open the .hex file you wish to load. The Help menu in MTK provides additional information. The bootloader also allows you to write to Port 1 directly by entering “W P1 xx,” where xx is a hex byte value. If you enter a value such as “W P1 55” or “W P1 AA,” the LED display will change to reflect the new outputs at Port 1. 5 of 13 DS89C450 Evaluation Kit Figure 3. Microcontroller Tool Kit Output USING THE DS89C450 EV KIT WITH THE DS5000(T) To use the DS89C450 EV kit as the evaluation board for the DS5000(T), it is necessary to first unsolder the DS89C450 from the EV kit. A 40-pin ZIF socket can then be soldered into its place to allow for multiple programming of the DS5000(T).
