dsPIC33F PRODUCT FAMILIES
The dsPIC33F General Purpose Family of devices are ideal for a wide variety of 16-bit MCU embedded applications. The controllers with codec interfaces are well-suited for speech and audio processing applications.
The device names, pin counts, memory sizes and peripheral availability of each family are listed below, followed by their pinout diagrams.
Operating Range:
⢠Up to 40 MIPS operation (at 3.0-3.6V):
- Industrial temperature range (-40°C to +85°C)
