hi,
does anyone know where in EU is it possible to order a few pieces of ARM cpu with MMU (or any 32bit cpu with MMU)? I'd like to develop a small board capable of running Linux.
thanks
I built many boards with Motorola PowerPC CPUs (MPC8xx). These have
a built-in MMU and are able to run Linux. These CPUs can be ordered in
small quantities by EBV electronic (www.ebv.com)
You can't buy a chip from ARM, only development board
Otherwise there are several manufacture of uC with ARM core
For example Samsung, look at http://www.arm.com/ARMPower/57ZEQU/$File/ARM_Microcontroller_Spreadsheet.xls
It depends what peripheral have to be implemented and which clock
frequency. The 'lowest cost' variant is the MPC852T with 10/100MBit
Ethernet, 3 serial lines (2 also capable for 10MBit Ethernet), Memory-
Controller, ... at a speed of 50MHz (=50 MIPS). It costs about 15US$
for 100Pcs. 1 Piece will cost about 25US$.
There also exist types with integrated LCD-Controller, more ports, ...
For Information about the chip --> look at motorola homepage
For pricing --> look at www.ebv.com, but these prices are normally
about 20% to high.
The board I built have much I/O's and peripherals. So I think they are not
as interresting for you. But it's possible to buy very small PowerPC-boards
(e.g. TQM860 and so on, try Google). Perhaps you have a chance to get
schematics and layout of such a board.
