Hi All,
This is a general question just to clarify what a MCU like the LPC2148 or
LPC2888 is meant for?
Perhaps my search hits for these MCUs have all yielded results which suggest
that these typicallyare used in Audio-Video sort of devices.
Are there any users in this group who have used a(any) LPC in a Utility Industry
Embedded system, which sits out in the sun and rain?
Does Philips manufacture a particular MCU which they claim to be meant forthe
Utilityindustry?
Please suggest.
Best regards

I have used the LPC2368 for a quality meter.
In the architecture, there is also an FPGA to perform FFT and other
minor math stuff.
The design has been working ok for 1 year. No complains.
The environment temperature where this guys is sat is between 0C and
65C.
Several test were done before entering into production, and the only test
we had some trouble with, was the EFT.
But regarding to your question, LPC2368 performs well for that application.
In the circuit there is: data gathering (coming from external ADs), heavy
computation (some aided by the FPGA), logging, and TCP communication.

I am using LPC2148 for an ecu on my motorcycle. it has 6 analog sensors
, 1 stepper motor, 3 injectors , 2 relays. been using 5000 km. without a
problem. tested form -4 C to +38 degrees C air temperature, sea level to
1955 mt. , under rain and snow also. There is a lot of electrical
noise on the bike you know.

Tim,
Pretty Interesting and thanks for your input too....You've intrigued my curiosity....
Whatdoes your ECU do?
Jorge... a follow up question for you... are you running an OS on your quality meter?
Cheers

No OS. All was built from ground.
However, we're considering now a Micrium and RTK, althoug none of them have
been implemented yet into our equipment.

It is a fuel injection controller. bike was carburatted before. removed
carburattors and switced to injection. controller reads intake air
temperature, engine temperature, throttle position, battery voltage,
intake manifolt pressure, crank position and o2 level in the exhaust.
than calculates injection openin duration and angle. also displays some
data on an lcd like a road computer style.
