       ZiLOG. Totally Logical. (TM)


               0. Introduction.


     All of the following prepared me
based on the company's site ZiLOG. Since most of the 
information carried advertising character, the "comb" it was 
pretty hard ... ;))) So sorry for some inconsistencies of 
presentation. 


     BTW, 1999 is an anniversary year for
ZiLOG - the company turns 25 years old. Long
Live ZiLOG!!! :)))


     1. Briefly about the company ZiLOG, Inc.


   Industry - of course, Semiconductors:)

   Specialization - appliances,
communications, integrated solutions.

   The representative - Microsoft ;-)

   Customers - Mitsubishi, Sony, Samsung.

   Structure - a private corporation.

   CEO - Curtis J. Crawford.

   Revenue in 1997 - $ 260 million

   Staff - 1,530 employees, but still
requires new, ;-) so that you have
chance to get a good job ;-)

   Head office - Campbell, CA.

   Web-site - http://www.zilog.com


    2. General information about the issued

                products.


   Currently ZiLOG produces 8 -
16 - and 32-bit microprocessors and embedded devices 
(incidentally, their TV controllers also support such a miracle 
as the Violence Blocking;)), as well as other equipment and 
software (in particular, embedded modems and DSP-processors).



   Of the manufactured products worth mentioning unfading 
processor family Z80 (Z80, Z180, Z380), a novelty - Processor

Z8 Plus, embedded modem module
Z02400, M@il.TV (communications console for the "general 
population", as claimed by ZiLOG). 


   The new processor Z8 Plus (relating to
Class One-Time Programmable - sorry, still
do not fully understand what it is - can
type of FPGA / ULA?) hit the top ten
processor 1998.


   As for the Embedded Modem
they work with conventional telephone lines at speeds of 2400 
and 9600 bps, and are used where very important savings space 
and low power consumption. 


   For new products you plan to use technology "Xtensa" from
Tensilica (about this later on, ie
K. was too lazy to download, and even more so -
read the press release ;-))


   Although it is said that the glitches can not
be, but the company, according to her own assertion,
completely solved the problem in 2000 for
the entire spectrum of their products.


        3. Nice family Z80.


   More details about the most advanced
representatives of this large and happy family
I will tell you the next time (when will deal with descriptions 
of 670 kb in pdf-format), and now present a small comparative

Table ...



    Options / Processor Z80 Z180 Z380


  Data bus width 8 bit 8 bit 16/32bit


   Address space of 64k 1Mb 16Mb

 Call-in register sets Feb. 2 8x16 bit

Cycles per team, min. 4 3 2

Productivity (otnos.) 2.5 November 1933



   Looking at the table, all just have to rush to put Z380 in 
its components, since in one interrupt will fit at least twice 
as many ticks! ;-))) 


         ... to be continued ...
