<DIV><BR></DIV>Vim ze se v techto krajich moc nepouziva Renesas (spolecna
firma Hitachi <BR>a Mitsubishi), ale podle jejich tvrzeni jsou v 16-ti bitech
1. na svete, <BR>v 8-mi bitech 2. na svete a ve 32-ti bitech 3. na
svete.<BR>Pouzivame procesory z rady R8C/Tiny (16 bit), H8/300H Tiny a
SH7760:<BR><A

je, ze v jejich nabidce si vybere opravdu kazdy. Od procesoru s <BR>20-ti piny
po obrovske stroje.<BR><BR>Priklad: Pouzivame maly procesor R8C/1B z rady
M16C. Je to 16-bit <BR>procesor v pouzde 20 pinu SSOP SMD. Ma 2 seriove
kanaly, jede na 20MHz, <BR>16kB flash, 1kB RAM a 2kB "virtualni" EEPROM (je to
vlastne flash). Ma <BR>on-chip debugger po jednom pinu (MODE). Pripojim
emulator E8a:<BR><A

muzu ladit v konkretnim zapojeni.<BR>Uzemenim pinu MODE prejde MCU do loaderu
a jednoduchym programem od <BR>Renesasu po seriove lince nahravam program -
firmware.<BR>Takovy procesor mezi jinymi (PIC, Atmel) tezko najdu (hlavne ty 2
<BR>seriove kanaly).<BR><BR>Novejsi rada R8C/2A-2D ma interni oscilator 40MHz
s presnosti +-2% v <BR>rozsahu napajecich napeti 2.7-5.5V a v rozsahu teplot
-20 +85°C.<BR><BR>Na Amperu mela firma MCS velmi zdarilou prednasku (podle
me). Mam z toho <BR>i nejake PDF, pokud by byl zajem, muzu to hodit na web ke
stazeni (asi <BR>6MB). Na par strankach jsou popsany vlastnosti low cost rady
a strucne <BR>vypichnuty jejich "prednosti". Mam i kompletni DVD s veskerou
<BR>dokumentaci, vyvojovymi nastroji, AppNotes atd. ke vsem procesorum
<BR>Renesas (zase od MSC). To uz ma 2.8 GB.<BR><BR>Martin Hanek<BR><BR><BR>Jan
