DB-LQFP48-LPC2103 Future Designs

DB-LQFP48-LPC2103 USB-Dongle and Derivative Boards The DB-LQFP48-LPC2103 is the Derivative Board for the LPC2103 microcontroller in a 48 pin LQFP package. The DB-LQFP48-LPC2103 requires the use of the USB-Dongle for power and a programming interface. The USB-Dongle and DB-LQFP48-LPC2103 allow quick and easy ICP programming of the LPC2103. The unit also provides a low cost platform for testing or prototyping of simple microcontroller based designs. The USB- Dongle provides a Virtual COM Port interface to the PC and allows hex files to be downloaded and programmed using Flash Magic or other common utilities. The USB-Dongle provides all power needed by the various Derivative Boards so no external power supply is required. Low cost Derivative Boards are available for many different microcontrollers from NXP. Please consult our website for details at www.teamfdi.com Highlights Low cost tool for prototyping USB-Dongle Kit Includes: USB port powered so no external USB-Dongle Power Supply required Download docs and Supports USB 2.0 software examples at Plugs directly into any standard USB www.teamfdi.com/USBDongle Port great for laptops Derivative Boards for Works with NXP free Flash Magic many microcontrollers software that can be downloaded are available from the web Technical Details The DB-LQFP48-LPC2103 uses a Target Interface PCB edge finger connector to interface to the USB-Dongle. The USB-Dongle includes a 14 pin connector to the Derivative Board that utilizes the following signals. Not all signals are used on all Derivative Boards: ISP/ICPn 5V (USB power, unswitched) Switched Power (3V for ICP) or Reset (Low True) Reset (High True for 8051 ISP) (for ICP & LPC2000 ARM) Ground 3V (unswitched) PCL/SCL (ICP/I2C) PDA/SDA (ICP/I2C) TXD (UART) RXD (UART) MSIO (SPI) PSEN/P0.14 (ISP entry) Board Dimensions 2.268 x 1.5 SCLK (SPI) MOSI (SPI) Example of USB-Dongle and Derivative Board USB-Dongle DB-HVSON10-LPC9103 Headers The DB-LQFP48-LPC2103 brings every pin of the microcontroller out to a standard 0.10 spacing header footprint for easy probing of signals or to support prototyping or wire-wrapping. Consult the DB-LQFP48- LPC2103 schematic if there are any questions about pin alignment from the microcontroller to the headers. Power The USB-Dongle provides the regulated 3.3V power required by the DB-LQFP48-LPC2103 and an onboard LDO, U3, provides the regulated 1.8V. The DB has a power measurement jumper, JP1, to allow the user to easily measure the power consumption of the microcontroller. In the artwork, JP1 pin 1 is shorted to pin 2 so the board is continuously powered. The board can be easily modified by cutting JP1 and loading a standard 0.10 header. LED - A green activity or status LED is provided at location D1 on the Derivative Board. This LED can be used to indicate when the microcontroller is being programmed or for other types of user activity under software control. Crystal or Clock Frequency - The DB-LQFP48-LPC2103 is clocked by an external 12.000 MHz crystal oscillator located at position Y1 on the DB.
