Microchip PIC32MZ 32 位 MCU 嵌入连接解决方案Microchip 公司的 PIC32MZ 是 200MHz 32 位嵌入联 MCU，具有高达 2MB 闪存,512KB RAM, 10/100 以太网 MAC，高速 USB MAC/PHY 和两个 CAN 端口，处理器性能高达 330 DMIPS 和 3。28 CoreMark/MHz，支持 WQVGA 图像，可用新一代嵌入设备.本文介绍了 PIC32MZ 主要特性和框图, MIPS32＆reg ； microAptiv 微处理器核主要特性和框图,以及 PIC32MZ 嵌入式连接（CE）入门板主要特性，电路图,材料清单和 PCB 元件布局图。The PIC32MZ Embedded Connectivity family of 200 MHz 32-bit microcontrollers feature up to 2 Mbytes of flash, 512 Kbytes of RAM, a 10/100 Ethernet MAC ， Hi—Speed USB MAC/PHY, and dual CAN ports. The processors yield 330 DMIPS and 3.28 CoreMark/MHz performance, with an interrupt latency of only 10 clock cycles, and have direct support for a WQVGA graphics。The chips are said to have class-leading code density and have a 28 Ms/s 12—bit A/D converter and a crypto engine with a random number generator. They use Imagination’s MIPS microAptiv core ， which includes 159 DSP instructions that enable algorithms with up to 75 ％ fewer cycles than previous MCU versions 。 QFN ， TQFP ， VTLA ， and LQFP packages with 64 to 144 pins are available starting in December and priced from 6。68 ea/10，000.
