Stock depleting, be quick if you still wanna pick up some PMS150C!

There's a new category on Padauk's website called PML series
There are some speculation that it might be a new series of low power (or even single cell battery?) MCU.

Datasheets for the PML100 have been published. Looks like the L stands for "LED", not "low power", as the PML100 has "One set triple 11bit SuLED (Super LED) PWM generators and timers".
Though operating current at 1 MHz is also 50% lower than for the PMC150. And power save current (stopexe) is much lower than PMC150 (5 µA vs 400 µA). Power down current (stopsys) is slightly higher, though.

P.S.: Interestingly, despite the memory sizes covered by the pdk13 architecture, this is actually a pdk14 device, as we can see from the "ASM_INSTR SYM_85A" in PML100.INC.

The PFS172/173 series seems to be discontinued and no longer available. The follow up is the PFS122/123 series which only seems to have a 12bit ADC instead of the 8bit ADC. At least the PFS122 is available right now:

Will there be a support in easypdkprog too?

Those look particularly interesting - reading through the datasheet they have a "limited voltage programming mode" where it uses 5.0V volts only, which means a simpler programmer with no voltage shifting shenanigans could be doable.

Support can be added as soon as I can get hold of some ICs.

Those look particularly interesting - reading through the datasheet they have a "limited voltage programming mode" where it uses 5.0V volts only, which means a simpler programmer with no voltage shifting shenanigans could be doable.
In the development branch you can see already some devices (e.g. PFC151/PFC161/PFC154/PFS172/PFC232) which use limited voltage programing mode.

The main gist of limited voltage programing mode is that VPP is set to 0V during programing phase (only VDD of apx. 4.8V needs to be supplied).
However to activate the special programing mode you still need 2 different voltages for VDD and VPP where VDD < VPP-1.5V
So yes... this would make it possible to omit the DCDC booster, but setting variable output voltages for VDD and VPP is still a thing.

Hi JS, do i see this correct that you could have VDD switchable between 3.3V and 5V,
and to activate 'special programming mode' you could do VDD 3.3V, VPP 5V.
Then later set VDD to 5V ?
on-board switching between 3.3V and 5V, with a reasonably low current, could probably even be done with an analog switch ..

I would like to use padauks (PFC154,PFC232,PFS122) in multiple projects now. Ideally programmable in the board, by higher level micro.

Happy to support the development efforts not only with praise but also with material.

We will do a WS2812B output driver and an I2C software slave.

Thank You.

Now I have working write and read :)

I made BIN decoder.
Start decoding from configuration words (0x76 in BIN; "xdat", 4B len, 32B configuration words, 2048B data....)
Output: 1024W data, 16W config.

"ny_dec(buffer, 16+1024);"

Code: [Select]
uint16_t nop_bin[16+1024] = {
