I am using PIC16F18875 controller in my design but i am planning to switch to a higher clock pic from pic18f series. I was looking for microchip product selector but I want suggestion before picking up randomely.
The PIC18 Q43 and Q84 series are a good upgrade path if you want to stick with the 8-bit architecture.yes. that one option also i have but i as i said in my first post that i need suggestion before picking up. i never used other than pic16 series.
Hi @nsaspookThe PIC18 Q43 and Q84 series are a good upgrade path if you want to stick with the 8-bit architecture.

That is a killer.14. Module: Core
Certain combinations of code sequence, code placement, VDD, FOSC and temperature may cause a corrupted read of fetched instructions or data. A corrupted instruction fetch will cause the part to execute an incorrect instruction with unpredictable results. Microchip cannot predict which combinations of these conditions will cause this failure. If this failure mechanism exists in your system, it should become evident during statistically significant preproduction testing, using your particular code sequence and placement, across multiple date codes. Preproduction testing should exercise all the functions of your application across system variables. Any changes to code should be tested in the same manner prior to being implemented.
I vaguely recall you mentioning some Q43 or maybe, Q83 micro. Not sure.I think I posted that a interface board with a PIC18 was obsolete.
‘It may or may not execute its instruction set.’ I remember those. Dark, frustrating days. Errata for the chip combined with errata for the ICE 2K/4K bondout chips, full speed maybes and device sensitive compiler bugs made for some pretty convoluted build-time switch hierarchies.I think I posted that a interface board with a PIC18 was obsolete. Look at the errata sheet for the chips you select for possible candidates.
Some are, IMO losers.
