P89LPC900 Family
Under the moniker of P89LPC900, NXP Semiconductors have introduced an entirely new family of 80C51 successors that have a number of pins ranging from 8 to 80 and are all based on an (in-system-programmable) flash memory. An important characteristic of the controller is that despite a large number of new features it is still fully compatible with the 80C51.
One of the most significant features of the P89LPC900 Family is that the core now requires onlytwo clock cycles per instruction. 8051 experts will already know that this used to be 12 or 6 cycles until now.
HT-ICP200 ICP Programmer Board for P89LPC900

In-Circuit Programming (ICP) is a method intended to allow commercial 
programmers to
program and erase P89LPC900 series devices without removing the microcontroller from the system.
The ICP facility consists of a series of internal hardware resources to
facilitate remote programming of the P89LPC900 through a two-wire serial
interface. NXP made ICP in an embedded application possible
with a minimum of additional expense in components and circuit board area. The ICP
function uses five pins (VDD, VSS, P0.5, P0.4, and RST). Only a small connector needs to
be available to interface your application to an external programmer in order to use this
feature.
The ICP programming method is a serial programming method, shifting in programming commands and shifting data in and out with a clock and dataline.
Using ICP on the application board has many advantages:
- The latest software revision can be loaded into the product before shipping.
- Field updates can be made when reprogramming the chip on the application board.
- In the debug stage of development the chip can stay on the application board while being reprogrammed.
FlashMagic is the preferred software used to perform ISP on the P89LPC900 series of Flash Microcontrollers that support this programming method. To provide the same programming Interface but still do the ICP programming method that the LPC90x devices require, we had developed ISP-to-ICP Bridge Board HT-ICP200 that can translate between ISP and ICP.
By adding another USB-to-UART Board HT-MP213 to HT-ICP200, you will have USB connection to program the NXP P89LPC900 series of u-controller.
