CY8C4013SXI-400 PSoC 4
8KB Flash 2KB SRAM

A few penny's higher than msrp but not by much.

Put 8 on a board and make your own Prop/Parallela as that would give you 64KB Flash + 16KB RAM, 8 cores at 16 MHz each
1.71-V to 5.5-V operation, for the cost of $2.50
Lacking a little in the ADC department.

    I remember looking at those, - they are lobotomized with only i2c (no UART, no SPI, or ADC, & just one timer )

    I think the EFM8BB10F8G-A-SOIC16 is a better "Cute little bugger", as it adds 12b ADC, UART, 25MHz, SPI, five timers, and is a lower price per IO pin....

    Cypress has a couple of very low-cost (only $4!) kits for the PSoC 4:

    http://www.cypress.com/?rID=92146&source=shop

    They only have a bootloader - no debugging. The MiniProg3 at $89 is required for SWD programming and debugging.

    tonyp12,

    Interesting device. I have no idea what I would do with it. Seems to be targeted at building capacitive sense buttons.

    It certainly won't make any Parallella Epiphany chip with it's lack of floating point, inter processor communication grid or clock speed.

    You could make some kind of franken-prop with it but then you only have a handful of I/O per chip, at least two of those will be used for chip to chip communication.

    Nice form factor and price, I like the snap-off idea for breakout boards.

    I could see uses of replacing complicated gate logic with a single chip+software.
    Programmable blocks for children to put circuits together
    External support-mcu when dedicated use of a core is important for no time glitches due to IRQs.
    here is a $10 swd debugger http://www.ebay.com/itm/1pcs-J-Link-OB-ARM-Debugger-Programmer-Downloader-replace-v8-SWD-M74-/351235114957?pt=LH_DefaultDomain_0&hash=item51c73e87cd

    The low-low-end 29cent only have 5 gpio, two can be used as i2c (advanced with fifo)
    and as the only included module is pwm the other 3pins could be used for that.
    Pretty decent pwm features (http://www.cypress.com/?docID=48755) 
    ❐ Timer
❐ Counter
❐ Capture
❐ Quadrature decoding
❐ Pulse width modulation
❐ Pseudo-random PWM
❐ PWM with dead time
■ Multiple counting modes – up, down, and up/down
■ Clock pre-scaling (division by 1, 2, 4, ... 64, 128)
■ Double buffering of compare/capture and period values
■ Supports interrupt on:
❐ Terminal Count – The final value in the counter register is reached
❐ Capture/Compare – The count is captured to the capture/compare register or the counter value equals the compare value
■ Underflow, overflow, and capture/compare output signals that can be routed to dedicated GPIOs
■ Complementary line output for PWMs
■ Selectable start, reload, stop, count, and capture event signals for the TCPWM from the dedicated GPIOs with rising
edge, falling edge, both edges, and level trigger options

    Freescale now also have sub50cents ARM0 and is less lobotomized than the above.

    KE04 series also have the same wide 2.7 to 5.5 V range:

    Wow, s/h 1/ea

    7.99 Mouser
    11.58 Digikey
  • tonyp12tonyp12 Posts: 1,951
    You did not look for cheapest option:
    Mouser: Economy Shipping (3-10 Days) $4.99
    Digikey: U.S. Postal Service First Class Mail $3.54

    As I order $50-$200 most of the time, shipping cost is rather negligible as their prices are low
    P.S Mouser don't charge sales tax and overall are ~10% cheaper.

    Freescale also have free samples with no shipping charge, if you really are penny pincher and don't mind filling in all those fields.

    Don't get me started....
    29 cents seems compelling, but then I need 1000 boards and 1000 headers, and 1000 voltage regulators, and 1000 capacitors, and 1000 ???

    Pretty soon just one Propeller 1 with board attached looks far saner an investment.

    I fear you are robots just dreaming of unrequited robot affection while caught in an infinite shopping loop.

    Free Samples? They only get you so far. These item may be given away for good reason, too tiny. SOIC8? After all the support components, you are still suffering restricted GPIO.

    ++++++++
    I feel that reading the specs and prices of devices with too few GPIO is futile. My personal sentiment is that I would much rather have a device on hand too many i/o pins than a device with too few.

    SOIC8 is too I/O constrained for general use.

    The KE04 looks more attractive and handles 5V. And more I/O is always a good thing.

    NXP has a similar device that is available in DIL8:

    http://www.nxp.com/products/microcontrollers/product_series/lpc800/LPC810M021FN8.html

    I even designed a PCB for it and had a few made:

    Please contact me if you would like one (free).

    That part has very small Code, for an ARM, and has no ADC, and has a 'go-away' price point of
    100 $2.3985 (ouch)

    The SiLabs EFM8BB1 has more IO, includes 12b ADC and is 100 $0.46970 for 4K version.

    I was going to mention the 810 as well, because I like that there is a nice small ARM for 'simple' projects.
    However at $2-3, they are out of the running as far as a cheapie.
