COMSOL has the largest range of embedded development tools in Europe.

Intel's 8048 and 8051 microcontroller families

The 8035 8039 8048 8049 8748 and 8749 all seem to have the same pin-layout and instruction set, but it's different from that of the 8051.

Compiler

C

Dunfield

Check out www.dunfield.com. Their $99 compiler/assembler/monitor (..and lots of goodies) package is very good value.

I have a C compiler for 8051 microcontroller.
This package include compiler, linker, debugger, assembler..

New Micros

New Micros Inc in the USA has a 8051 board, the NMIY0031, which costs $39,-- excluding shipping and handling. The board has 8051 CPU, Bootprom with monitor and downloader, 8kRAM, RS232* interface, prototype area ...... A C-compiler, assembler, linker and some more accompany the board. Shipping by parcel service cost about $20,--, so better find some friends do cut these relatively high costs. I am using it for a few months now, getting started gave some troubles using the C-library, which consists of dozens of small C-sources, but now it works fine. I also use the IAR C-compiler at work, which generates more compact code, but isn't cheap to buy privately. Send an e-mail to general@newmicros.com to request more information.

SDCC

I have developed a FreeWare openSource optimizing compiler for 8051 and Z80 based MCUs.
The code generated by the compiler is second only to that of Keil's... it generates better code than ALL the other commercial compilers in the market today.

SPJ Systems

See SPJ Systems.

"C compiler for 8051 with Source Level Debugger" (SLDC51)
It includes a 'C' compiler (with built-in linker and assembler), a librarian and a source level debugger.

Discontinued parts

8XC152JX product discontinuance notification

As part of Intel's effort to continually invest in state-of-the-art technology, and because of changes within the market segment, Intel will cease offering the 8XC152JA, 8XC152JB, 8XC152JC, and 8XC152JD microcontrollers. All combinations of package types, operating frequencies, and memory sizes of these microcontrollers will no longer be developed, manufactured, or marketed.
