PIC32MZ2048ECM144-I/PH
PIC32MZ2048ECM144-I/PH - 200MHz 32-Bit MCU 2MB Flash | Microchip
The Microchip Technology PIC32MZ2048ECM144-I/PH is a 32-bit MIPS32 microAptiv PIC32MZ Embedded Connectivity (EC) microcontroller integrating 2 MB Flash and 512 KB SRAM, operating up to 200 MHz with 3.3 V I/O in a 144-pin TQFP (16x16 mm, 0.4 mm pitch) package. The MIPS32 microAptiv core delivers 330 DMIPS and 3.28 CoreMark/MHz, while dedicated peripherals cover HS USB 2.0 Host/Device/OTG, 10/100 Ethernet MAC with MII/RMII, two CAN 2.0b controllers, I2S for audio, and a parallel master port for graphics. According to Microchip datasheet 60001191G, the part is designated Not Recommended for New Designs (NRND); customers should migrate to the pin-compatible PIC32MZ2048EFM144 family that adds a hardware Floating Point Unit and 252 MHz operation.
A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a high-performance processor core, Flash program memory, SRAM, and a rich mix of analog and digital peripherals on a single die. Within the embedded taxonomy, the PIC32MZ EC sits in the high-performance connectivity tier between 8/16-bit MCUs and application processors, targeting industrial HMI, audio, and connected-embedded designs. Its hypernyms are MCU, embedded controller, RISC processor; common synonyms are 32-bit MCU and Cortex-M-class competitor (although the core is MIPS, not ARM).
Key differentiating features of the PIC32MZ2048ECM144-I/PH include 2 MB dual-bank Live-Update Flash supporting field firmware upgrades without downtime, 512 KB SRAM, 4 KB EEPROM emulation, a 12-bit 18 MSPS ADC with up to 48 analog channels, six UART, four SPI, five I2C, and Peripheral Pin Select (PPS) for flexible signal routing. The 32-channel DMA controller and eight output compare / PWM modules make it well suited to multi-protocol industrial stacks running FreeRTOS, OPENRTOS, or Micrium OS-III.
Architecturally, the device combines the microAptiv scalar pipeline with a tightly-coupled SRAM block, dedicated DMA, and a hardware crypto accelerator supporting AES, 3DES, SHA, MD5, and RNG for secure connectivity. Compared with the older PIC32MX series, the EC family delivers roughly 5x the Dhrystone performance and adds Ethernet, CAN, and HS USB on-chip, eliminating external PHY transceivers in many designs and reducing BOM cost.
Typical applications include industrial Ethernet gateways, building automation controllers, automotive infotainment/CAN nodes, audio processing with I2S codec interfaces, and graphical HMI panels using the PMP. Engineers should consider migrating to PIC32MZ2048EFM144 (FPU + 252 MHz, pin-compatible) for new designs because the EC family is officially NRND.
When designing, observe the 3.3 V supply requirement and use a 24 MHz crystal with the on-chip PLL to derive 200 MHz; the I/O banks tolerate 5 V inputs. Decouple each VDD/VSS pair with 100 nF plus bulk capacitance within 5 mm of the pins.
