Connectivity is everything these days. If you canít talk to the outside, itís hard to make a compelling case for a product. Devices need to be connected either to the Internet, to an intranet, or some other outside medium. Component makers have gotten much better simplifying this process. One example is the latest 32-bit MCU family announced by Microchip. The companyís 24-member PIC32MZ Embedded Connectivity (EC) family offers a performance level of 330 DMIPS and 3.28 CoreMarks/MHz.
Note that the inclusion of a 10/100 Ethernet MAC, a Hi-Speed USB MAC/PHY, and dual CAN ports help support those communications applications. The family also offers a broad set of wired and wireless protocol stacks. Thatís combined with a full-featured hardware crypto engine with a random number generator for high-throughput data encryption/decryption and authentication, a key for applications that need to communicate.
The PIC32MZ is Microchipís first MCU to employ Imaginationís MIPS microAptiv core, which adds 159 new DSP instructions that enable the execution of DSP algorithms at up to 75 percent 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.
The first 12 members of the family are expected to sample in December, with the remainder coming by sometime next spring. Pricing starts at $6.68 each in 10,000-unit quantities.
