AFAIK, Renesas is #1 in total Market Share according to Gartner which also reported PIC as #1 in revenues.

how about the 8051 manufacturers?

in the next few years wala sigurong ibang licensing na mangyayari (of course except for ARM). kanya kanya sila ngayon all competing to be the best but only making MCU religion out of people using them. at the licensing stage, it's not the popularity that counts, it's the revenue that it can generate. parang yung Renesas na lang, andaming hindi nakakaalam dito sa atin pero number 2 na sila sa competition sa Certain Processor para sa cellphone.

obviously, popularity and revenue belong in the same sentence..

Why would atmel license the 8051? Cant they make their own mcu? of course they can, and they did later on. But 8051 is already popular, and would mean large revenue so they took it

wala na kasing reports masyado about the total 8051. naging puro company based na in the last years. merong mga reports pero bihira yung publicly published.

$2000++ yata para ma-view yung mga ganung report. hehe.

ang maraming reports ARM. pero total shares, wala rin masyado.

Renesas, maliit ang revenues nila pero malaki ang market share. andami kasi nilang expansion at malaki gastos sa marketing strategy, free kits.

yung PIC32 nagkaroon din nito (before the start of PIC32 challenge ata), IIRC, pero as usual banned tayo. late ko na rin nalaman 'yun, papahingi sana ako sa tita ko. hehe.

nung kinuha nila yung 8051 wala pa silang capability mag-design ng sarili nilang MCU architecture. mas malaki na ang kikitain nila kung i-license na lang yung 8051 kaysa mag-hire ng tao at mag-spend ng matagal na oras sa R&D.

AVR - thesis daw ng 2 student. dito na nagsimula buksan ang Atmel Norway at lahat ng related sa MCU development nila sa Atmel Norway nangyayari halos. sa simula nung AVR gumawa sila ng Pin Compatible sa 8051 MCU's nila para mapabilis ang migration ng users ng 8051 nila.

kumuha rin sila ng license ng ARM7 (AT91SAM7) kahit meron silang sariling AVR32. mas mabilis naman ang time to market dahil pwede kaagad mag-migrate yung ARM users. direct competition din ang AVR32 sa ARM pero mas makakakuha sila ng market kung gagawin nila 'to. hindi ko pa nakikita architecture ng PIC32 pero yung AVR32 medyo hawig din sa ARM, meron ding similar sa Thumb codes (16-bit instructions). yung Renesas version CISC.

ang TI nag-license din ng ARM7 pero hindi na ulit sila nag-develop masyado. pinapalaki na lang nila ang memory nung devices nila.

hello. pareho ba ang PIC16F84A-04/P sa PIC16LF84A-04/P? thanks

ang main difference sa kanila ay yung operating voltage.. yung LF kaya nya down to 2volts na Vdd..

-Can I control the speed of the electric motor of a washing machine using programming in PIC16F84A? PWM to be exact?

rdpzycho · « **Reply #89 on:** August 26, 2008, 08:22:22 PM »

depende kung ano ang motor ng washing machine niyo. maraming washing machine dito AC motor ang gamit instead of Universal Motor.

saan makakabili ng 8052 programmer at bootloader?

Bootloader na lang kailangan mo.

update....!

There is one time na may nakausap akong visiting Canadian software engineer in China lately - matandana nasa edad 65 na. Share ko lang :

1. Nag shift siya from hardware to software mid 40 na siya kasi nahihirapan na daw siyang magsolder. Software engineer siya sa mga security systems.

2. Nagtanong ako about PIC and 8051, nasabi niya na mas nauna ang PIC kesa sa 8051. Ang designer pala ng original PIC ay ang General Instrument (GI) ang una daw na PIC ay ang PIC1650 in early 1970 (if my memory is right, or maybe similar 16xx series) - ang grandfather daw ng mga PIC processor ngayon. Ang GI daw ay ibinenta sa Microchip Technology ang PIC business in the 1980. May nauna na rin nagsabi sa akin nito na engineer din mula sa Silicon Valley sometimes ago kaso baka nagbibiro lang kasi email lang iyon. How true? oh! Kaya siguro ang GI or Microchip hindi na nakuha pa ang 8051 dahil mayroon na pala sia PIC at that time na lumabas ang 8051 end of 70s (early 80s).

Ok pala sa software kahit matanda na -- sabagay kung hardware ka mahihirapan ka na pag-tanda, nanginginig pa mga kamay, hindi ka na maka-pag-solder pa, mahina pa paningin etc....

Up to this date, locally in Philippines and worldwide, sino na ang pinaka usefull MCU?

joycekram1021 · « **Reply #95 on:** June 24, 2010, 04:06:57 PM »

someone told me that PIC is good for beginners, i agree with that.

resources are all over the net.

rdpzycho · « **Reply #96 on:** June 24, 2010, 05:56:36 PM »

^ medyo mas madali ang Arduino para sa akin.

BTW, nung nagsimula akong mag-aral ng microcontroller, konti lang ang resources sa High Level Programming sa PIC, kaya assembly ako nagsimula. pero mas madali nung natuto ako ng PL/M-51 at C para sa 8051 .

ngayon, puro AVR na ang gamit ko. paminsan MSP430 dahil maraming nakatambak sa bin.

^ 'di ako master diyan.

ang gamit ko dati IAR, tapos sinubukan ko 'yung MSP-GCC. ngayon nakahingi ako ng libreng CD nung libre na Code Composer Studio, 8k ata ang limit sa code size. 'di ko gaanong napaglalaruan 'yung mga MSP ko ngayon, daming iniisip. hehe.

hehehe... sa totoo lang sis, tinatamad lang akong simulan ang pag-aaral. siguro kung aralin ko din, makukuha ko naman.
tulad din nung sa zilog, kung di napag-uusapan dito, do ko natutunan.

pati nga yung 8051...
siguro, daming kasing priorities...
