CHAPTER 5
THE PIC32MX440F256H MICROCONTROLLER
5. Introduction to the chapter
In this chapter is located the information about the heart of PIC32-PINGUINO-MICRO – its 
microcontroller. The information is a modified version of the datasheet provided by its 
manufacturers. 
5.1 The microcontroller
High-Performance 32-bit RISC CPU:
• MIPS32® M4K® 32-bit core with 5-stage pipeline
• 80 MHz maximum frequency
• 1.56 DMIPS/MHz (Dhrystone 2.1) performance at 0 wait state Flash access
• Single-cycle multiply and high-performance divide unit
• MIPS16e® mode for up to 40% smaller code size
• Two sets of 32 core register files (32-bit) to reduce interrupt latency
• Prefetch Cache module to speed execution from Flash
Microcontroller Features:
• Operating temperature range of -40ºC to +105ºC
• Operating voltage range of 2.3V to 3.6V
• 256K Flash memory (plus an additional 12 KB of boot Flash)
• 32K SRAM memory
• Pin-compatible with most PIC24/dsPIC® DSC devices
• Multiple power management modes
• Multiple interrupt vectors with individually programmable priority
• Fail-Safe Clock Monitor Mode
• Configurable Watchdog Timer with on-chip Low-Power RC Oscillator for reliable 
operation
Peripheral Features:
• Atomic SET, CLEAR and INVERT operation on select peripheral registers
• Up to 4-channel hardware DMA with automatic data size detection
• USB 2.0-compliant full-speed device and On-The-Go (OTG) controller
• USB has a dedicated DMA channel
• 3 MHz to 25 MHz crystal oscillator
