High-performance 32-bit MCUs
13 November 2013
DSP, Micros & Memory
Microchip released the new 24-member PIC32MZ Embedded Connectivity (EC) family of 32-bit MCUs. It provides performance of 330 DMIPS and 3,28 CoreMarks/MHz, in addition to dual-panel, live-update Flash (up to 2 MB), large RAM (512 KB) and connectivity peripherals including a 10/100 Ethernet MAC, Hi-Speed USB MAC/PHY (a first for PIC MCUs) and dual CAN ports.
The company touts the PIC32MZ as having class-leading code density that is 30% better than competitors, along with a 28 MSps ADC that offers one of the best throughput rates for 32-bit MCUs. 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.
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 failsafe way to conduct field updates while operating at full speed.
The PIC32MZ is Microchip’s first microcontroller 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.
