Over the last few years, we’ve seen projects and products slowly move from 8-bit microcontrollers to more powerful ARM microcontrollers. The reason for this is simple — if you want to do more stuff, like an Internet-connected toaster, you need more bits, more Flash, and more processing power. This doesn’t mean 8-bit microcontrollers are dead, though. Eight bit micros are still going strong, and this week Microchip announced their latest family of 8-bit microcontrollers.
The PIC16F15386 family of microcontrollers is Microchip’s latest addition to their portfolio of 8-bit chips. This family of microcontrollers is Microchip’s ‘everything and the kitchen sink’ 8-bit offering. Other families of PICs have included features such as a complementary waveform generator, numerically controlled oscillator, a configurable logic controller, power saving functionality and the extreme low power features, but never before in one piece of silicon.
This feature-packed 8-bit includes a few new tricks not seen before in previous Microchip offerings. Of note are power management features (IDLE and DOZE modes), and a Device Information Area on the chip that contains factory-calibrated data (ADC voltage calibration and a fixed voltage reference) and an ID unique to each individual chip.
As you would expect from a new family of PICs, the 16F15386 is compatible with the MPLAB Xpress IDE and the MPLAB Code Configurator, a graphical programming environment. The products in the family range from 8-pin packages (including DIP!) with 3.5kB of program Flash to 48-pin QFPs with 28kB of program Flash. The goal for Microchip is to provide a wide offering, allowing designers to expand their builds without having to change microcontroller families.
All of these chips can be sampled now, although the lower pin count devices won’t be available through normal means until next month.
