DB-TSSOP-LPC922

DB-TSSOP-LPC922 USB-Dongle and Derivative Boards The DB-TSSOP-LPC922 is the Derivative Board for the P89LPC922 microcontroller in a 20 pin TSSOP package. The DB-TSSOP-LPC922 requires the use of the USB-Dongle for power and a programming interface. The USB-Dongle and DB-TSSOP-LPC922 allow quick and easy ICP programming of the P89LPC922. 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 Target Interface The DB-TSSOP-LPC922 uses a PCB edge finger connector to interface to The USB-Dongle includes a 14 pin connector to the Derivative Board the USB-Dongle. 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 1.793 x 0.8 SCLK (SPI) MOSI (SPI) Example of USB-Dongle and Derivative Board USB-Dongle DB-HVSON10-LPC9103 Headers The DB-TSSOP-LPC922 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-TSSOP-LPC922 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-TSSOP-LPC922. 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-TSSOP-LPC922 is clocked by the on-board oscillator in the LPC922 at a frequency of 7.373 MHz so no external crystal is needed on the DB.
