Functional Deviations of LPC2124
IAP.1: Flash memory programming interface timing problem
Introduction:
The Flash memory on the LPC2124 offers In-Application Programming (IAP) functionality. The IAP
routines are part of the on-chip boot loader software, which controls the interface between the digital
logic and the Flash memory. Please note that all programming methods (JTAG, ISP, IAP) use IAP
calls.
Problem:
Due to a timing problem in the interface between the Flash block and the digital logic the following
problem may occur:
If the boot loader revision in the device is previous to V1.63 then in up to 10% of the devices the
Flash memory interface, at some point during an IAP programming or erase operation, may never
return from the IAP call. Please note that devices that pass the IAP programming are functional and
do not suffer from any long-term reliability problems.
Devices with a date code prior to 0425 (manufactured before week 25 in 2004) are generally
affected by this problem unless you receive devices with updated boot loader software from your
distributor. Parts marked with date code 0425 or later are not affected by this problem. Please refer
to page 2 of this document for details on how to identify the date code.
Workarounds:
1) The on-chip boot-loader software can be updated via ISP to correct this issue. The boot loader
update files can be downloaded here:

lpc2000_bl_update.zip
The boot-loader version can be read out using the Philips Flash ISP Utility which can be found here:

lpc2000_flash_utility.zip
Both links can also be found on the product information page for this product under the Support &
Tools section which can be found here:

2) Limiting the external clock frequency to 12 MHz AND making sure the on-chip PLL is turned OFF
while programming any part of the Flash memory reduces the likelihood of the occurrence
significantly. During In-System-Programming the PLL is turned off by default.
