content: Just thought this may be of interest to some here. I had a meeting with an FAE last week and he told me about a new PSoC4 chip, the 4000 series.I was pretty amazed at the specs/price. No digital blocks, but ARM M0 core, 16Mhz, 8k flash, 2k SRAM, has a serial communication block, and supports the TCPWM block.$0.40/ea in singles, $0.35 in 100's and $0.29 in 1000's.I was pretty blown away. Don't work for Cypress or anything, just use their chips and really like 'em. Hoping for a little DFN package PSoC4 like Atmel has.

content: https://www.eevblog.com/forum/microcontrollers/highly-anticipated-low-end-mcus/msg414243/#msg414243Got myself a 4200 and a 4100 (no analog on the 4100) also I got the pioneer kit with a PSoC4 and a PSoC5LP on it with arduino headers.Nice chips.But as far as I know they all have digital blocks. The 4100 lacking analog blocks.Edit: nevermind so 4000 series are new,http://www.cypress.com/?rid=94456for the dev kit at $30 (includes a PSoC5LP on it as well)Interesting. BTW the PSoC 4200 chip goes for $1 free shipping, but $.40 is nice!link to the new lower cost chip for datasheets etc:http://www.cypress.com/psoc4000/Edit again: this I think is the one they were talking about:http://www.cypress.com/?mpn=CY8C4013SXI-400The rest are more expensive than 40 centshttp://www.cypress.com/?rID=94034

content: Quote from: miguelvp on June 01, 2014, 05:36:15 amYes, they start at $0.40 for the SOIC-8 version of the PSoC 4000 series, and they go up from there.One thing to keep in mind - I had the hardest time figuring out what the hell those $1 PSOC4200 chips were (CG7999/8000/8001)... the part number is mentioned nowhere in any of the datasheets. After asking my FAE, it turns out it's a special program the marketing department is offering, so those $1 prices are for a limited time, I was told through at least end of Q2/2014 (so perhaps ending soon).Having said that, if anyone is working on a commercial project, they really should get in touch with Cypress and work with them... my volume is really low... like under 5,000 chips per year in total, but they were willing to give me a huge (and I mean HUGE) discount on the chip I needed in order to beat the price of the Atmel part I was previously using. And that particular product was only consuming maybe 1000 chips per year. And the PSoC they price-matched was so much more feature rich that it wasn't much of a fair comparison with the Atmel on features.. but they still price matched.

content: It's not much of a SoC if it doesn't have any programmable digital or analog blocks, and the serial controller only does I2C, is it?Still; I have a great fondness for <$1 microcontrollers.(They need a flash 'read accelerator' on a 16MHz(!) part?!)

content: The PSOC 4 serial block (SCB) does USART, SPI or I2C.I think the datasheet is just badly worded where it states the SCB "implements a I2C master", I think it should state that is "can" implement a I2C master. I'll have to try it PSOC creator and see if it compiles with a SPI or UART.It's an interesting device at that price.edit: scrap that, else where in the datasheet they've qualified it as being a SCB-I2C. Pretty clear that it's only a I2C peripheral. That's a shame.

content: I have been using the Cypress PSOC for about a year now got one of there CY8CKIT a little pricey but excellent products I prefer the PSOC3 but once you get used to there software working with the chips is extremly easy i would even say easier then the Arduino and your code is in C so you are learning something that cares over to other platforms unlike the Arduino i highly recommend. Let me clarify the development kit was pricey the actul devices are very cheap.Jason
