Hello Friends .......
I am new to LPC2000 family and new to board design also ;
1. Can you suggest any method to connect SJA1000 (CAN controller ) to
LPC2148 micro controller ;
2. SJA1000 CAN controller has multiplexed ADDRESS & DATA bus ; But LPC2148
has no external bus ; so is it possible to use GPIOs of LPC2148 as
MULTIPLEXED ADRRESS cum DATA Bus ?

The LPC2368 is cheaper, has two integrated CAN ports, and the features
of the LPC2148. The CAN peripheral in the LPC series is based on the
SJA1000 IP.

LPC2129 is a good suggestion in order to substitute the LPC2148.
Its cheaper and more elegant to work with a device that has CAN inside,
specially Philips devices...
There are lots of 'ready to cut and paste' codes for LPC2292 and LPC2129.
Take a look at the files on lpc2000 page group.
Modify your sch design, read the datasheet and the errata sheet for this
device and good luck...
