to gchapman: Are you on some sort of mailing list that you get announcements for all these new documents that you post?  Is there some forum or web page at Microchip where they are announced?

 

(In any case, thank you for reposting them here, attached to relevant threads!)

You're welcome!

 

P.S.

A foundry's application engineers, by significant effort and work, create application notes and source code that expands on what's in the data sheets (ideally created by design engineers)

Same application engineers may write trade journal articles though these journals aren't like the ones in the past (circa '10)

Same engineers attend conferences that are now virtual (where's the swag?)

(sucking sound from the drain)

Chin up!

Rev. DS40002198B - 02/2021 | AVR® Instruction Set Manual

1.Editorial change, code examples needed beautification.

2.Corrected instructions affecting two registers had a syntax that did not compile as inline in avr-gcc or xc8.

3.Defined overline symbol as negation.

4.Corrected core overview for AVR® DA Family AVRxm to AVRxt.

5.Added to core overview AVR® DB and AVR® DD Families.

6.Reintroduced the Conditional Branch Summary table with some simplification.

I really don't understand what are DD and DE families for. All of them seem to be practically identical and no significant improvement since ATmega4809. I wish new AVRs have USB working as Virtual COM Port. This would be really nice to get rig o CP2102/FT230... old XMEGA AU serial have USB and this was really useful.

Low pin count (growth from tinyAVR 0, 1, and 2-series)

mega4809 has a single-ended ADC, no high frequency crystal oscillator, etc.; a mega4809 advantage is packaging (PDIP-40 vs PDIP-28)

Concur; maybe AVR DC.

USB is a mid-complexity peripheral; some difficulty to be complete, precise, and correct with USB and squeeze the USB controller into the limited die space.

Maybe AVR Dx USB access will be by another means (USB megaAVR : dual-port RAM, USB XMEGA AVR : pseudo dual-port RAM and the four RMW instructions)

Yet there's innovation in USB UART :

  • crystal-less
  • very high baud
  • 24MHz clock to the MCU

... and XMEGA B & C.

I looking forward to -DD because of the package size. 4mm QFN vs 5mm makes *a lot* of difference to me. Then I can drop SAMD11 which is too memory-constrained (although it does have USB, if you can afford the memory use).

There are so many monolithic buck converters, some which only require outboard capacitors. Don't see why one would build one oneself.  You can control the voltage with a filtered PWM signal to bias the Feedback pin.

  • voltage
  • digital control (in primary or secondary)
  • digital compensation (flexibility in matching load to source as either or both change impedance)

though current BCD processes and designs have transistors with significant drain-source max voltage; there are significant use cases for 40Vdc and greater (power tools, mowers, engine start-stop, hybrid EV, etc)

or a DAC though DAC are more prevalent in follow-on AVR.

One of the main reasons to switch the power with a micro is to be in sync with the switching noise.

AN3998 - Sensorless BLDC Motor Control for AVR® Microcontrollers

[last sentence of page 1]

The presented solution creates a cost-effective motor driver by using an 8-bit microcontroller when traditionally, only 16-bit microcontrollers or more were used in creating this device.

The motor control board could drive the motor for some water well pumps; Plug-In Module (PIM) for AVR DA and AVR DB are forthcoming.

Coupon codes are nice, but can anyone actually buy anything from them?

I have been trying to buy the DB48 eval kit for the last hour, but I can't get past the checkout. It says there is something wrong with one or more fields in my address, but all is fine when I look. The address is the same as last time I ordered from Microchip Direct, and back then there was no problem.
