Product Description

Note: This revision is currently retired. Please see the updated Wi-FIRE

Introducing the chipKIT Wi-FIRE: The first chipKIT to feature the latest, most powerful chip in Microchip's MZ microcontroller portfolio.

"The PIC32MZ family provides [2.5x] the performance and 4x the memory over the previous-generation PIC32MX families, along with a high level of advanced peripheral integration. For applications requiring embedded connectivity, the family includes [Hi-Speed USB, Ethernet], along with a broad set of wired and wireless protocol stacks." 
"The PIC32MZ is Microchip's first MCU to employ Imagination's MIPS M5150 core, which adds 159 new DSP instructions that enable the execution of DSP algorithms at up to 75% fewer cycles than the PIC32MX families. This core also provides the microMIPS® instruction-set architecture, which improves code density while operating at near full rate, instruction and data cache, and its 200 MHz/330 DMIPS offers [2.5x] the performance of the PIC32MX." – Microchip Press Release 

Building on the previous successes with the chipKIT WF32, the Wi-FIRE uses the same 43 available I/O pins, 12 analog inputs, 3.3 operating voltage, 4 user LEDs, potentiometer, buttons, uses MRF24 on-board wireless module, microSD Card, dedicated SPI Signals and high efficiency switching 3.3V switching power supply for low-power operation. 

Where the boards differ is in what the PIC32MZ processor can deliver. 

The Wi-FIRE is significantly faster than its WF32 counterpart, with 200 MHz operation speed, 2MB of Flash, 512kB RAM, High-Speed USB and a 50MHz SPI. The PIC32MZ core includes the MIPS M5150 CPU Core from Imagination Technologies. The M5150 is a highly efficient, compact core that is optimized for cloud-connected based projects, using Imagination Technologies' FlowCloud software. 

The Wi-FIRE can be programmed using MPIDE and with the addition of a compatible in-system programmer/debugger, can be used with the more fully featured/advanced Microchip MPLAB® X IDE.
