Features & Applications

Microchip provides solutions for the entire performance range of 8-bit, 16-bit, and 32-bit  microcontrollers, with a powerful architecture, flexible memory technologies, comprehensive  easy-to-use development tools, complete technical documentation and post design-in support  through a global sales and distribution network. Microchip offers two 16-bit Microcontroller (MCU) families plus two  16-bit Digital Signal Controller (DSC) families that give you compatible options across a wide spectrum of price, performance and feature sets.
Common attributes among all 16-bit MCU and DSC families are pinouts, software, peripherals  and development tools. Whether your design requires the lowest-priced 16-bit solution, the  most powerful 16-bit MCU in the industry, or DSP capability, Microchip offers a broad range  of products while preserving the compatibility that help save you time and money on  subsequent designs.
The PIC32MX440F128L-80I/PT is a 32-bit Microcontroller which has 128 KB of Flash Program Memory with 85
I/O's and USB-OTG. It's maximum CPU speed is 80 MHz with an operating voltage range of 2.3 V - 3.6 V in a 100-Pin TQFP package. It has an industrial temperature range of -40°C to +85°C and is lead free.
