Hi all

This is bit old MCU but can you please advice the cheap programmer that I need to flash . I have AVR ISP hoped it can not support

Thanks in advanced

Hi Dayan.

I would suggest you use USB-ICP-LPC9xx from FDI.

USB In-Circuit Programmer for LPC9XX – USB-ICP-LPC9XX - FDI - Future Designs Inc.

USB-ICP supports the new In-Circuit Programming or ICP mode on NXP Semiconductors microcontroller families such as the LPC9xx. In-Circuit Programming uses a two-wire serial interface to program and erase ICP enabled microcontroller devices without removing them from the system. The ICP function uses only five pins: VCC, GND, PCL, PDA, and RSTn. A small connector is all that is needed to interface your application to the USB-ICP programmer.

Have a great day,

Dear Jun Zhang,

Thanks for the advice and information

USB ICP from DFI little high price for my budget. Can you please provide me a schismatic to design the PCB it like serial port support which can be used to connect flash magic software

Thanks in advanced

Hi Dayan,

The programmer schematic is other company's business and we don't have.

I guess the USB-ICP-LPC9XX programmer from Future Designs Inc that I suggested is perfect for that.

LPC922F has been out of life for ten more years. You need contact the programmer producers if they are available for sale.

Options:

Advantech LabTool series
Advin SpeedPro series
BPM various programmers
CooCox CoFlash
Data I/O various programmers
Elnec various programmers
ESAcademy FlashMagic ISP SW
FDI USB-ICP-LPC9xx
Hi-Lo Systems ALL-100
Leap Leaper / SU / AH
Phyton ChipProg series
pls UDE MemTool
Raisonance RFlasher7
SMH Technologies FlashRunner for LPC
Xeltek SuperPro series
ZLG SmartPRO / EasyPRO

Have a great day,
Jun Zhang

Grate Thanks for the reply

Dear Please see the attached image for MCB 900 schismatics

https://1drv.ms/u/s!AvrJlo2hoIofgxj1i5cfzgcsEyBs

My question is

In the image black cycle parts is serial port and IC

I am planing to design a PCB as per Black cycle area . Once I completed the PCB can I able to flash the LPC922F MCU with Flash magic software

Please advice

Thanks in advanced

Hi Dayan,

I can't open your link.

Besides, can you please shed light on your questions?

Can anyone reveal the ICP programming algorithm used by the P89LPC90x microcontrollers ?
Certainly after ~17 years, the secret can be revealed !

I wish to build my own programmer for ICP (I mean true ICP, not IAP).

Thanks

I found the NXP document "P89LPC900 In-Circuit Programming (ICP) Specifications" which gave me the information I needed.
