Microchip has unveiled the new 24-member PIC32MZ Embedded Connectivity (EC) family of 32-bit MCUs. Designed to support increasingly complex application the MCU provides 330 DMIPS and 3.28 CoreMarks/MHz, in addition to dual-panel, live-update Flash (up to 2 MB), large RAM (512 KB) and the connectivity peripherals – including a 10/100 Ethernet MAC, Hi-Speed USB MAC/PHY, which is a first for PIC MCUs, and dual CAN ports.
Microchip says that the PIC32MZ has class-leading code density that is 30% better than competitors, along with a 28 Msps ADC. Completing this family’s high level of integration is a full-featured hardware crypto engine with a random number generator for high-throughput data encryption/decryption and authentication such as AES, 3DES, SHA, MD5 and HMAC, as well as the first SQI interface on a Microchip MCU and the PIC32’s highest number of serial channels.
With the demand for additional features growing all the time embedded designers require more MCU performance and memory, but at the same time they are looking to lower cost and complexity by using fewer MCUs. By providing 3x the performance and 4x the memory over the previous-generation PIC32MX families, in addition to a high level of advanced peripheral integration, these new devices look to address that need.
For applications requiring embedded connectivity, the family includes Hi-Speed USB, Ethernet and CAN, as well as a broad set of wired and wireless protocol stacks. Many embedded applications are adding better graphics displays, and the PIC32MZ can support up to a WQVGA display without any external graphics chips. Streaming/digital audio applications can take advantage of this family’s 159 DSP instructions, large memory, peripherals such as I2S, and available software.
Field updates are another growing challenge for design engineers and managers. The PIC32MZ’s 2 MB of internal Flash enables live updates via dual independent panels that provide a fail-safe way to conduct field updates while operating at full speed.
“Our new PIC32MZ family was designed for high-end and next-generation embedded applications that require high levels of performance, memory and advanced-peripheral integration,” said Rod Drake, director of Microchip’s MCU32 Division. “The PIC32MZ enables designers to add features such as improved graphics displays, faster real-time performance and increased security with a single MCU, lowering both cost and complexity.”
The PIC32MZ is Microchip’s first MCU to employ Imagination’s MIPS microAptiv 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 3x the performance of the PIC32MX.
Three new PIC32MZ development tools are available now. The complete, turn-key PIC32MZ EC Starter Kit comes in two versions to support family members with the integrated crypto engine (DM320006C) and those without (DM320006).
The Multimedia Expansion Board II (DM320005-2) can be used with either Starter Kit to develop graphics HMI, connectivity and audio applications. The 168-pin to132-pin Starter Kit Adapter (AC320006), enables development with Microchip’s extensive portfolio of application-specific daughter boards.
Starting in December 2013, the first 12 members of the PIC32MZ family are expected for sampling and volume production, while the remaining 12 members, as well as additional package options, are expected to become available at various dates through to May 2014. The crypto engine is integrated into eight of the PIC32MZ MCUs, and there is an even split of 12 MCUs with 1 MB of Flash and 12 MCUs with 2 MB of Flash.
