Embedded Market Trends 8-bit Microcontrollers
Legacy is a primary driver for new designs
Familiarization, code base, tool-chain consistency
Investment in 8-bit by other suppliers has decreased
Microchip introduces the significant majority of new 8-bit MCUs
“Cores” evolve slowest of all factors
Functions in customers’ end applications evolve fastest
Realization that SW-centric design has hidden costs
Software validation efforts take more time than the design itself
To be competitive, modern 8-bit MCUs require:
Fast development time
High functionality & evolving peripheral integration
Balance software dependency with deterministic hardware
performance

Customer Testimonials MCC Development Experiences
“It was quite easy. You could graphically see what you wanted to do, and
then go in and decide how you wanted to set things up and it took
care of all the details.”
- Kevin Rochford, Autoliv
“We use the MCC all the time. It allowed us to do in 2 hours what took
several days of digging through datasheets in the past.”
- Patrick Marcus, Marcus Engineering
“I had five peripherals running in less than 30 minutes, and this was the
very first time I used this tool.”
“I have configured registers by hand and I can safely say this program
saves at least 90% of project startup time.”
- Craig Beiferman, Universal Laser Systems
“It was the tool I was looking for to speed up development with new
boards.”
- Saul Ollenides, General Electric
