TI alternative for PIC18F67J60

Other Parts Discussed in Thread: MSP430F5529, ENERGIA

Hi

One of my client uses PIC18F67J60 microcontroller in their application its parameters are as following

Flash memory 128kb

RAM 3kB

EEPROM=0

64 pins/39Ios

CPU freq is 42MHZ

And inbuilt ether connectivity. 

Can anyone recommend me TI alternative for above microcontroller? Cost should be similar 

  • You can easily do selection yourself:

  • I will rephrase my question does TI has MSP430 microcontroller with ethernet capabilities

  • >I will rephrase my question does TI has MSP430 microcontroller with ethernet capabilities
    Of course not. Msp430 is low power uC.

    Microcontrollers with built-in Ethernet:
    www.ti.com/.../products.page
  • Tiva C series has it but it is over kill for his project
  • MSP does not have built-in Ethernet.
    But if you would go to the link Ilmars provide you and;
    Select in the left pane ‘Performance MCUs’.
    Select the tab ‘Products’.
    Select the check box ‘10/100 ENET’.
    Select more features of your choice.
    And you get a list of available MCU’s.
  • All are from Tiva C. Anyway thanks for help
  • >Tiva C series has it but it is over kill for his project
    Well... it is. What's worse - AFAIK those PICs with 10Mbps Ethernet MAC+PHY is kinda unique in particular price/performance spot. In your place I would ask distributor to seek for alternative - in case you need to switch manufacturer for some reason.

    What about a Microchip ENC28J60 connected to a TI device via SPI?

    From a quick look at datasheets the ENC28J60 has a 10base-T PHY and a 8-Kbyte Transmit/Receive Packet Dual Port SRAM as does the PIC18F97J60.

  • Hi actually this uc is perfect for clients application and this chip turns out to be cheapest solution than MSP430+ENC28J60 and I was pushing for TI uc because apart from pic everything is TI chips
  • At 100pcs TI+28J60 is not cheapest solution. I am still open for solutions till 7th July 8th is design freeze date if nothing new is offered we will stick with pic right now I am getting ENC28J60 for 2.53$ I want some TI uc with 50 GPIO for 2~3$@ 100pcs from TI store. (Preferably one available on launchpad) I had shortlisted MSP430F5529+28j60 but pic is still cheapest solution
  • I don't know why TI is allowing itself to loose customers in the Ethernet area.
    Wiznet W7500 a $2.65 ARM0 with hardware tcp/ip stack and MII interface www.mouser.com/.../

    Add a 82cent transceiver (MII/RMII) and you good to go.
    As Microchip have bought both smsc and micrel they cornered the transceiver market, though TI make a few:

  • Cant agree more with you! TI has some many versions of microcontroller as well as other ics but whats really needed that stuff is not there!
  • >Cant agree more with you! TI has some many versions of microcontroller as well as other ics but whats really needed that stuff is not there!

    I would like to disagree here.

    msp430 is aimed at low power segment. Ethernet devices are far from low power, at least from msp430 perspective. Additional illustration of what I mean is datasheet of mentioned PHY, page 64. It's power-down consumption is 2x bigger than msp430 consumtion running at 1MHz and 1000x times bigger compared to LPM3 of msp430. 

    If you want microcontroller with Ethernet from TI - just take proper chip.

    p.s. I doubt TI would do such an (censored) move to throw money away designing chip just to make hobbyists happy.

  • $10 and 128pin, that will not get the maker-faire-people interested,
    remember these DIY maker will one day be full fledge engineer and will have a bias towards something they already used.

  • >remember these DIY maker will one day be full fledge engineer and will have a bias towards something they already used.
    Engineer who is trying to make ANY possible device out of only known to him msp430 microcontroller is no good engineer at all.
  • >$10 and 128pin, that will not get the maker-fair-people interested,

    Tiva Launchpad is not that expensive to keep maker-fair-people interested enough.

    I always wonder why makers want to connect 16KB code size microcontrollers to Ethernet, want to connect video camera to chip having 2KByte of RAM and so on. Right decision making is also part of good engineering.

  • I would like to see a ($5) 64pin msp432 w/ MII by next year.
    There is a Ethernet to Zigbee/Bluetooth gateway market were a 128pin tiva is overkill.

    Instead of max 48Mhz, make it 50MHz so the transceiver can share a 25Mhz clk.
    You could always put a LDO with enable for the transceiver if it use to much power.

    Wonder if you could sip enough power from cat5e wire without using POE to at least wake up a msp432+supercap once an hr so it can do its thing.

  • TI need to have something go between MSP430 and Tiva C series. Hopefully MSP432 will fill the gap.
  • Same thing i was going to say!
    And regarding makers TI need to tap in students. Take my example during my student days TI supported me with free samples and now I am using TI products only!
    And Ilmars if you check AVR freaks forum during early days of arduino all senior people mocked it criticised it. Later what happned? Atmel and arduino tied up! Even Intel tied up with them. ST's official evaluation board is arduino compatable. Now TI is supporting Energia!!! If you check article on Adafruit in IEEE Institute they made 33million last year just by selling maker stuff!
  • >I would like to see a ($5) 64pin msp432 w/ MII by next year.

    Again msp432 and Ethernet is kinda conflicing each other. Msp432 still is wristwatch processor. Wristwatches do not neet Ethernet connectivity. Why don't you ask just lower pincount and cost for Tiva?

    >There is a Ethernet to Zigbee/Bluetooth gateway market were a 128pin tiva is overkill.

    Today's trends are that such kind of devices better have to be " smart" - with nice looking built-in web interface. Tiva with 1Mbyte flash barely meets code size requirements to run IP stack and decent web server.

    BTW for " quickly putting your small uC on the internet" ESP8266 is nice one. Puts WiFi BoosterPack in dust.

    They do indeed. Please do not get me wrong! I do not say that TI shall stop approaching makers and students. I just say that Ethernet do not fit msp43x microcontroller. After all TI even have connectivity solution for msp430 - WiFi Booster Pack.

  • I almost took you wrong! In my application microcontroller is driving some relays and reading couple of sensors. All its doing is collect data and send over ethernet or read ethernet and toggle some gpios. All the processing is done by master so tiva is over kill so as of now sticking with pic only.

    PS: due to reasons we cannot use anything other than ethernet.

    Yes, then stick with pic if you find it fit for your application. After all this is how market works - various manufacturers offer various products having different features. If they all would manufacture identical products, then most of them would be long gone.

  • Once they get a nice official lite version of a XCC compiler setup the ESP8266 will for sure be used in commercial development.
    It has a 160MHZ Xtensa LX106 core and cost $3 ($5 for module) When TI's and others cost 4x that, they must not seen this coming.
