8051 STILL ALIVE!
GENERAL, CAN, USB AND MP3 MCUs BY ATMEL!
Microcontrollers based on the 80C51 core have been declared extinct for some time now.
Despite the maturity of this architecture, many manufacturers continue to develop new
products based on the 80C51.
Take ATMEL's X2 core for example, with ISP Flash, EEprom and a host of other features. It
offers twice the performance of the 80C51 at an identical clock rate. Most importantly,
however, all of the software that customers have developed for the 80C51 over the years
can also be used with the X2, without limitations. In fact, these MCUs are more widespread
today than ever before, and they now offer CAN, USB, MP3 and Smart Card interfaces.

ATMEL offers a broad range of products
based on the 8051 core. Of course, they all use flash memory for the program memory, and
there are also derivatives available in OTP and mask versions. Depending on the type, the
flash memory is programmed either in parallel using a device programmer, serially via in
system programming (ISP) or using the built-in bootloader (self programming). The
bootloader is factory-programmed by ATMEL and is located on-chip in a separate EEprom
block. It can be modified by the user. What's more, several different models feature an
additional EEprom block for data memory.
If you're looking for a controller with a USB, CAN or ISO7816 (Smart Card) interface, or
maybe even an on-chip MP3 Decoder, then ATMEL is the right choice for you.
That's because ATMEL's broad range of ASSP 8051 controllers includes all of the above. All
models come with self-programming flash, as well as a wide array of additional features.
Low-cost tools are available for ATMEL's entire line of ASSP products to help get
development going quickly. The tools can be used for serial programming, in conjunction
with ATMEL's FLIP software, using the RS232 interface of a PC.
