Hello,

You are making a mistake in rebuilding a 40 pin 8051 version of the
ARM controller.

I teach microcontroller applications to bachelor students.
We use 8051 devices with more peripherals (and connections) than the
40 pin 8051 (ADuC832, AT89c51cc03, C517,...).

You have to use a controller for it's real purpose.

Need low pin count, time deterministic programming and low cost
(component and PCB) use a PIC, STx, AVR or MCS51 device.
(wide voltage range, low component count and wide pitch components for
low PCB cost)

Need functionnality? Then cost is not always a problem. Then use the
ARM. But use ALL it's functions (or make them accessible).
I have build PCB's for the LPC2103 and LPC2138. The component count to
get it working is to high for 8051 applications.
We use 10 pin headers to get all de I/O out. The board itself contains
 a minimum component count to get it working:RS232 level shifter,
reset and boot buttons, voltage regulators (3.3 and 1.8), 9 pin D-type
connector and jacks for IIC and SPI interface. 

This allows anybody to get started fast. There is no need to use loose
wires to get the board running.

Problems start when starting with components, not with ready to use
starter kits.

With regards
