OK, keep on your 8051 and gimp cave, and let the people that think out of the box do the job
Also, check this 2nd video and tell me do you know any other processor that you can make small analog circuits on the fly?

Not to mention that it would me much easier to use off-the-shelf op amp - nothing needs to be done, no programming required. And, most importantly, you can select the op amp with characteristics you really needs. Chances that a built-in op amp with arbitrary characteristics is exactly what you need are slim to none.
It's not only opamps, it's a full set of analog components, of course, you can't argue against because you never tried, and already makes clear that will never do that, because the tools isn't on your OS preference, let follow your course and pray for your eventual competitors don't take advantage of this wonderful piece of silicon (Psoc) against something you are planning to compete using Linux friendly tools

They won’t compete.
At least in China nobody bothers using PSoC at all. It is way too expensive to be competitive in the market.
You can check Aliexpress or Taobao for MCU dev kits. You would be hard pressed to find something with PSoC on it. OTOH kits based on STM32, STC 8051, Microchip PIC16 and AVR just floods the market. Also check the bookstores and college curriculums, there is virtually no book or course that even touches upon the advanced features of PSoC.
The STM32 line is so popular we are now even seeing clones from China in the form of GD32 line.
Psoc kit 059 sells at $10 with no quantity limit. You can buy 1000 pcs if you want to.
The kit contains 2 $20 chips (target and debugger) and passives.
The debugger can also be used as usb to uart and i2c bridge.
You cannot judge by the price of the development kits. Manufacturers sell them below cost to attract buyers to their chips. Look at the prices of the chips themselves instead.

And how much does the STM32 kits cost again? $15 for STM32F407ZGT6 + 1MiB external SRAM + 16MiB external Flash.
Cy8ckit-059, as low as RMB 80 from Taobao.
Mouser, e14 and Digikey all ship to China, some with minimum order amount.
Brokers like rightIC also do aggregated shipping to China from western distributors with very low MOQ and shipping cost.

OK, keep on your 8051 and gimp cave, and let the people that think out of the box do the jobOh and speaking of 8051, I am not using it as my main microcontroller choice for the projects. I have a series of blog posts exploring 8051 and that's it. I have way more ARM and AVR based projects than 8051: [...]

For $20 I can get the Allwinner V3s stack up, sample the analog signals directly and crunch through the entire PSoC analog chain using software code. Oh that is a Cortex-A7 core with full FPU and SIMD instructions.
PSoC can sample analog at 20-bit without audio filtering shit (not 24-bit audio ADC), it's a general purpose precision 20-bit sigma delta ADC.
PSoC also has 2 SAR ADCs that support arbitrary channel sequencing.
PSoC has a few <50ns comparator that gives you 20MHz bit stream bandwidth.
PSoC has IDACs and VDACs, with a fairly accurate and stable voltage reference.
PSoC has comparators and OPAMPs with very low offset (and ADCs with factory calibrated for offset) that can be used on mV signals.
PSoC has switching capacitor analog handling blocks, which can be used for programmable analog filters, comparators and a lot of other purposes.
PSoC has the best cap sense in industry, comparable with TI CapTIVate solution.
PSoC is available in extended temperature range and comes with MISRA C certified libraries.
And most important, PSoC consumes milliamps, and can boot up in milliseconds.

If your product profitability is heavily bounded by the cost of a single commodity MOSFET, it's likely your design is not good enough. Generally if you want to start a real innovative business (not a mom&pop shop), you need to make sure your BOM is only a very small portion of cost, expect R&D and testing/certifying as well as financing cost amortized per product to be more than BOM.
BTW, IRF540 and IRF540N are of the same price on Mouser. Taobao price doesn't really have a meaning unless you can get the certificate of authenticity from supplier. Who knows the IRF540 you get is a genuine one or a Chinese die packaged into an IR packaging.

Who knows the IRF540 you get is a genuine one or a Chinese die packaged into an IR packaging.The kicker is not IRF540N/IRL540N, but the additional complexity just to accommodate the PSoC. A negative rail just for the single external op amp to flip the sense line voltage is ridiculous. Also it is much simpler to design a boost SMPS than inverting SMPS, as chips are readily available. No thanks I will stick to my cheap STM32F103C8T6 + TLC5615 + TLC2272 stack.
1. PSoC's internal analog peripherals can operate down to negative rail (gnd).
2. If it's just for signal conditioning, PSoC can be used to create a charge pump to generate negative voltage. Port 12 in PSoC 5 can handle up to 25mA per pin.
3. The same can be used to drive a non logic FET, and you can use a BJT to do analog level translation. I prefer a common base driving a complementary emitter follower (aka. class B) for gate driving. 2 9014 NPN and 1 9015 PNP is guaranteed to be cheaper than any OPAMP.
Using PSoC you will save thousands of dollars on development, it's a system on a chip, smaller PCB's, more flexible and integrated solution, ideal for the middle of complex things on the very low scale of production, you can even use the development stick as a component of products.
They are not made to compete with STM8 or STC8051 for 1 dollar Led Voltmeter
The main application is medical and military devices and measure and automation, where you want performance and system integration that only PSOC can give you, The learning curve is hard, but if you pass that learning phase you can make a full complex system in a day. The saving isn't on the chip, the saving in on engineer time, your product will be ready faster and the gain on development cost and time will pay the premium of the CPU.
Psoc can read analog channels, filter at very high rates and generates a VGA signal showing the results, and having excellent capacitive buttons and sliders while at the same time generating one analog out in a range outside your power supply limits using an internal cap switch, and generating several different clocks to be used externally based on the PLLs you can define.
Did you get it, it's unique
PSoC is also single source - I can swap processors or opamps as commodities, but buying a magic unicorn box is a great way to be sad at a later date.
If you intend to keep a product alive for longer times and keep maintaining it you damn well hope either Cypress the unicorn company stays alive for that long and still produces the chip you used (at least c compatible one) or you have used standard products that is easily replaceable.
Having all major components separated means I can swap parts without respinning the board
should one vendor ceased business.
Thats one of the almost un-achievable aspects of the hi tech biz these days. One only has to look
at the history since 70s of the number of very big companies that have been absorbed or gone out
of business, Philips, National....Whole product lines spun off into oblivion. And who is trained to see
the future ?

Insofar as Cypress is concerned, look at the annual reports as a starting point. Basically they have an
industry standard core coupled with a process that can handle mixed signal. That aspect one could
comfortably state will continue to experience demand. Look at the roadmap, also the frequency of tool
updates, release of new families, parts, as a way of telling if they are viable. The Cypress MCD div shipped
almost ~$1B in 2016.

Of course there are reliability issues with that approach. Power issues. And if a competitor sees those
increased costs and your market is sizable that's an opportunity to attack that solution. Eg. because
that solution has increased procurement, assembly costs, just a fact of life.
