1. Overview
PAB90x-1 (V1.1 and up) is a Programming and Evaluation Adapter Board for the
Philips 8-bit microcontrollers LPC901, LPC902, LPC903 in an 8-pin package.
(Whenever "LPC90x" is mentioned in this document, it refers to LPC901/902/903.
To program other LPC90x devices, e.g. LPC906/907/908, you need a different
programming adapter board called PAB90x-2.)
The PAB90x-1 board is designed as an add-on board to the MCB900 board from
Keil Software. (More information: http://www.keil.com/mcb900)
PAB90x-1 Programming functionality:
To program the 1K of on-chip Flash memory of LPC901/902/903 devices with
PAB90x-1, an MCB900 board from Keil Software is necessary. Before any devices
can be programmed, the P89LPC932 on the Keil MCB900 board needs to be
programmed with the ISP-to-ICP bridge code using the ISP software FlashMagic
(included on the CD). FlashMagic then also supports the programming of LPC90x
devices, however only in combination with the ISP-to-ICP bridge code on the
MCB900 as noted above. See sections 2 and 3 for details.
PAB90x-1 Evaluation Board functionality:
After the user code has been programmed using PAB90x-1 + MCB900 as
described above, PAB90x-1 can be used as a small stand-alone board to evaluate
the user software. The following elements are available for evaluation:
• LED:
PAB90x-1 provides one low-active green LED (D1) that can be hooked up to
any port pin of the LPC90x using the LED header pin.
• Potentiometer:
PAB90x-1 provides a potentiometer, which delivers 0V to 3.3V to the V_AN
("analog voltage") header pin.
