Psykhaze Posted August 8, 2016 Report Share Posted August 8, 2016 (edited) Just ordered some free samples from Microchip , did anybody has ever gave a try to PIC32MZ2048 family ? Took 2 of these : http://www.microchip.com/wwwproducts/en/PIC32MZ2048EFH064 Features Sounds huge even if package TQFP and price sounds low (-9€/pc) General 252 MHz/330 DMIPS, MIPS Warrior M-class core DSP-enhanced core: Four 64-bit accumulators Single-cycle MAC, saturating and fractional math IEEE 754-compliant Dual Panel Flash for live update support FPU for fast single- and double-precision math 12-bit, 18 MSPS, 24-channel ADC module microMIPS mode for up to 35% code compression CAN, UART, I2C, PMP, SQI & Analog Comparators SPI/I2S interfaces for audio processing and playback Hi-Speed USB 2.0 Device/Host/OTG 10/100 Mbps Ethernet MAC with MII and RMII interface 50 MHz Serial Quad Interface (SQI) Peripheral Pin Select (PPS) functionality to enable function remap Peripherals: 8 channels of hardware programmable DMA and 18 channels of dedicated DMA with automatic data size detection Six UART modules (25 Mbps): Supports LIN 1.2 and IrDA protocols Two CAN modules 2.0B Active with DeviceNet addressing support Six 4-wire SPI modules (50 Mbps) SQI configurable as an additional SPI module (50 MHz) Five I2C modules (up to 1 Mbaud) with SMBus support Parallel Master Port (PMP) Hardware Real-Time Clock and Calendar (RTCC) Nine 16-bit Timers/Counters (four 16-bit pairs combine to create four 32-bit timers) Nine Capture inputs and Nine Compare/PWM outputs ADC / Audio: Onboard 12-bit ADC Module 24 inputs with integrated S&H Six digital comparators and six digital filters Audio data master clock: Fractional clock frequencies with USB synchronization Audio data communication: I2S, LJ, RJ, USB Audio data control interface: SPI and I2C™ Graphics interface: PMP Soft: MPLAB Harmony - PIC32 software development framework C/C++ compiler with native DSP/fractional and FPU support TCP/IP, USB, Graphics and mTouch middleware RTOS Kernels, Express Logic ThreadX, FreeRTOS, OPENRTOS, Micriµm, µC/OS and SEGGER embOS Bests, Jerome Edited August 8, 2016 by Psykhaze Quote Link to comment Share on other sites More sharing options...
lis0r Posted August 9, 2016 Report Share Posted August 9, 2016 I use these at work for testing, they're nice enough chips. I've been meaning to use some for home projects for a while now, but haven't gotten around to it yet. Lisa 1 Quote Link to comment Share on other sites More sharing options...
Psykhaze Posted August 9, 2016 Author Report Share Posted August 9, 2016 Ok nice . I will give it a try for a new core/aout concepts, as well as i am going to receive some free samples of microcontrollers and D/A converters.

Psykhaze Posted August 9, 2016 Author Report Share Posted August 9, 2016 (edited) @lis0r : I am also looking for newer replacement for 74HC165/74HC595 digital shift registers, eg something adapted to the PIC32 Bus bandwith / speed. Maybe some additionnal DMA memory chips too ? Maybe you have something to advice me or maybe a start point for some researchs ? Bests, Jerome Edited August 9, 2016 by Psykhaze DMA memory ask added Quote Link to comment Share on other sites More sharing options...
lis0r Posted August 9, 2016 Report Share Posted August 9, 2016 Nope, we've always used the 144 pin parts, so we've never had a problem with the amount of I/O. Quote Link to comment Share on other sites More sharing options...
Psykhaze Posted August 9, 2016 Author Report Share Posted August 9, 2016 (edited) @lis0r Ok thanks . Now i've ordered the 64 pins version i think i will try to stick to it . I was thinking about "simple" high speed digital mux/ demux if you may advice me something ? What about aditionnal external memory ? Maybe sticking to 144 pins version? Thanks again for your answers :) Bests, Jerome Edited August 9, 2016 by Psykhaze 144 pin version could fit ? Quote Link to comment Share on other sites More sharing options...
lis0r Posted August 10, 2016 Report Share Posted August 10, 2016 I'm afraid I can't really help much more - I use the board as a reference platform for developing our in-house RTOS and hypervisor products. We have been considering getting some boards made up with CellularRAM attached to the external RAM interface. These are basically DRAM+controller, packaged to behave like SRAM.

Psykhaze Posted August 10, 2016 Author Report Share Posted August 10, 2016 thank you @lis0r for everything,that's already a lot =) I also have to make searchs by my side ! Bests, Jerome Quote Link to comment Share on other sites More sharing options...
