PRODUCT DESCRIPTION:

LPC2148H is a Header Board designed for ARM7-TDMI Based LPC2148 controller from NXP. The Board is a basic IO Pinout Board with options of onboard power and USB Device. Remaining IO pins are taken out on 2.54 mm berg connector. The board has standard JTAG Connectivity for debug/programming.

Features:

  1. Controller: ARM7 Based LPC2148 from NXP.
  2. Package: LQFP64.
  3. Clock Used: 12MHz for Controller, 32.768KHz for internal RTC.
  4. Power: On Board, 5V and 3.3V.
  5. On Board reset and ISP switches.
  6. JTAG Connectivity Option.
  7. Test LED via IO Pin.
  8. On Board USB Device.
  9. Can be USB or external Powered.
  10. Board Specifications:
    • Dimensions: 89 x 51 mm.
    • No of Layers: 2
    • FR4, Blue Solder Mask, ENIG, 1.6mm thickness.

Kit Deliverables:

  1. LPC2148 Header Board
  2. USB Cable

JTAG Options for Debug/Programming:

Parallel Port JTAG (tested on Keil, Rowley CrossWorks)

CoiNel ARM USB JTAG (tested on Rowley CrossWorks)

The Board can also be used with other JTAG Debuggers (Check compatibility to ensure).

The details on how to use the JTAG and its associated plugins are provided with the documents and also can be downloaded from Download and Support sections.

ISP Programming:

Programming can be done through the on chip boot loader using UART interface (UART0). You will have to use a TTL to RS232 Converter to do so since the pinout are TTL logic and PC uses RS232 logic. The tool used for programming is Flash Magic

USB Boot Loader:

The Board can also be programmed via USB Secondary Bootloader. Check the document for LPC2148 USB Boot Loader for more details.

TOOLS:

Our products can be used with majority of IDE and plugins that support ARM7 LPC21xx family. A few IDE and plugin details are given below.

Plugins/Programmers:

H-JTAG, Flash Magic have been tested.

Compatible debuggers like U-Link, J-Link etc can also be used.
