What are the recent trends in the Microcontroller production?
Recent trends in the Microcontroller production, Arduino and PIC Microcontroller!
Some of the a lot of fascinating developments are within the very low-end 8-bit microcontrollers.
Take the PIC10F322 from Microchip for example. It comes in either a 6-pin SOT-23 or 8-pin DIP or DFN package and has only 512 14-bit words (896 bytes) of flash and 64 bytes of RAM.
But look at the unique group of peripherals (in addition to the normal timers, ADC, PWM, GPIO, WDT):
Configurable Logic Cell (CLC):
- 8 selectable input source signals
- Two inputs per module
- Software selectable logic functions including:
- AND/OR/XOR/D Flop/D Latch/SR/JK
- External or internal inputs/outputs
- Operation while in Sleep
So in several cases, you’ll be able to avoid adding extra logic chips to alittle system.
Numerically Controlled Oscillator (NCO):
- 20-bit accumulator
- 16-bit increment
- Linear frequency control
- High-speed clock input
- Selectable Output modes
- Fixed Duty Cycle (FDC)
- Pulse Frequency (PF) mode
Complementary Waveform Generator (CWG):
- Selectable falling and rising edge dead-band control
- Polarity control
- Two auto-shutdown sources
- Multiple input sources: PWM, CLC, NCO
Pretty fancy for a part that costs under 50¢ in large quantities. I work mainly with ((32-bit PIC)) processors, but I think this processor quite a diamond.
While other trends that have been true for decades. Higher levels of combination, particularly with new types of IO as RF (ESP-12/32, for example), a lot of memory of various sorts, quicker clocks, lower cost, lower power, smaller packages. I wouldn’t expect those trends to change much over the coming years or tens of years.
