In this mode, firmware can be implemented in on-board EPROM, or downloaded to program RAM. The RAM option provides a quick and easy method for testing firmware revisions. There is also a stand-alone mode which allows portable system operation without the PC attached. In this mode, user firmware is programmed in an EPROM, and only power need be applied to produce a fully operating emulated USB chip. Additionally, the board may be connected to a logic analyzer to facilitate full trace capability and complex breakpoints. Features • Full development and debug environment for Cypress Universal Serial Bus Controllers: — Real-time, full-speed emulation — Software breakpoints — Single stepping — Register, RAM, I/O display/modification • Debug environment operates without firmware modification • User code can be run from on-board EPROM or RAM • Stand-alone operation requires only power connection • Access to key microcontroller internal signals to enable trace and complex breakpoints • USB Specification Version 1.1 compliant, 1.5 Mbps speed • Emulator Board Support for Cypress USB IC family: • CY3650 — CY7C63000/1, 20-pin DIP/SOIC,Windowed DIP — CY7C63100/1, 24-pin SOIC, Windowed DIP — CY7C63200/1, 18-pin DIP, Windowed DIP • CY3651 — CY7C63410/1/2, 40-pin PDIP/48-pin SSOP — CY7C63413, 40-pin PDIP, 48-pin SSOP, 40-pin Windowed DIP — CY7C63510/1/2, 48-pin SSOP — CY7C63513, 48-pin SSOP, 48-pin Windowed DIP Logic Analyzer (Optional) Target System RS-232 To Serial Port USB Development System Power Supply PC Development Board Typical USB Development Environment Introduction The Cypress USB Developer’s Kit is a powerful tool that enables customers to develop USB hardware and firmware with emulated Cypress USB ICs. The development system can be run in two modes. In the typical development system environment, the board is controlled through a PC-based interface. Software running on the PC facilitates debugging through breakpoints, single stepping, and display and modification of Cypress Semiconductor Corporation • 3901 North First Street • San Jose • CA 95134 • 408-943-2600 October 1996 - Revised July 1997 www.DataSheet4U.com PRELIMINARY CY3650/CY3651 The Program RAM allows users to download code into on-board memory. This provides a quick and easy mechanism for firmware modification. The firmware can be modified after download by changing individual bytes of code through the debug interface. The CY3650 board supports program memory sizes up to 4 KB and the CY3651 board supports program memory sizes upto 8 KB; consult the data sheet of the actual target device for the ROM size contained in the IC. For stand-alone operation, user firmware can be burned into the supplied UV-erasable EPROM, allowing for operation without the PC attached. USB Interface Power Supply Development Board Target System Stand-Alone Environment Hardware Installation The development system is simple to install and get running. An enclosed 110 VAC wall transformer supplies power to the board. (Alternatively, a lab power source can be used.) Once the included software is installed on a Windows 3.1 or Windows ‘95 PC, an RS-232 cable connects the board to that PC to provide a full debug and monitoring environment. The cable and adapters support both a 9-pin and a 25-pin serial port on the PC. The CY3650 and CY3651 development boards support the low-speed (1.5 Mbps) USB mode, with a 1.5-kΩ pull-up resistor to +3.3V on the D− line for proper operation. The USB serial interface protocol engine contains the functions commonly referred to as “Serial Interface Engine” and “Serial Interface Logic” in USB literature. This provides full functionality for connecting to a USB bus as a low-speed device, including endpoint control and automatic NAKing. I/O Port Operation The general-purpose I/O ports on the board all operate identically. As outputs, the ports provide either a (removable) weak pull-up, or a strong pull-down. During a read operation, the digital state of all bits of each port are read together. All bits also have the capability to serve as interrupt inputs, as described in the device data sheets. The versatile 4-bit current-sink DAC per pin, available in many Cypress USB family ICs, is not implemented on the board. Support is available for customers who wish to fully emulate this IC feature Note : The input thresholds are lower (1.5 V) for the development board than the USB parts (.
