The Microchip Technology PIC32MM0064GPL036-I/M2 is a 32-bit microcontroller from the PIC32MM GPL family, built on the MIPS32 microAptiv UC core. It integrates 64KB of Flash program memory and 8KB of SRAM, runs at up to 25 MHz, and is housed in a 36-pin 6x6 mm SQFN package. According to Microchip product literature, this part is designed as a low-power, low-cost bridge between the PIC24F XLP and PIC32MX families. What is a 32-bit microcontroller? A 32-bit microcontroller is a single-chip computer with a 32-bit data path, CPU registers, and address bus, capable of executing complex instructions and addressing large memory spaces compared with 8-bit or 16-bit MCUs. The PIC32MM0064GPL036 sits within the broader hierarchy of: microcontroller -> embedded MCU -> 32-bit MCU -> PIC32 family -> PIC32MM sub-family -> GPL low-cost low-power group, and is part of Microchip's semiconductor product line. Key features include Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLC), 10-bit ADC with up to 24 channels, multiple capture/compare/PWM (CCP/SCCP) modules, I2C/SPI/UART communication interfaces, and a Real-Time Clock/Counter (RTCC) with calendar mode. The device operates from 2.0V to 3.6V, supports down to 35 µA/MHz active current, and offers multiple low-power sleep and idle modes optimized by the eXtreme Low Power (XLP) design philosophy. Architecturally, the microAptiv UC core delivers high code density via MIPS16e ASE and supports hardware multiply/divide, atomic bit manipulation, and deterministic interrupt latency. The 36-pin SQFN package exposes multiple VDD/VSS pairs for noise isolation between analog and digital domains, and the device supports JTAG and 2-wire ICSP programming/debug. Typical applications include low-power IoT sensor nodes, consumer electronics with capacitive touch via the Peripheral Touch Controller, battery-powered industrial sensor hubs, and cost-sensitive 32-bit upgrades for existing PIC24F designs. The wide ecosystem of MPLAB X IDE, MPLAB Harmony, and XC32 compiler support accelerates time-to-market. When designing with the PIC32MM0064GPL036-I/M2, take care to honor the VDD/VSS pairing rules from the datasheet to minimize digital switching noise on ADC inputs. The 36-SQFN exposed pad must be soldered to a sufficient copper pour for thermal and electrical grounding, as specified in the package land pattern. This page synthesizes distributor pricing, drop-in same-package alternatives drawn from the PIC32MM GPL family, and practical design notes not consolidated in any single manufacturer document, providing a decision-grade view of the part.

PIC32MM0064GPL036T-I/MV

PIC32MM0064GPL036T-I/MV - 32-bit 25MHz 64KB Flash MCU | Microchip

The Microchip Technology PIC32MM0064GPL036T-I/MV is a low-power 32-bit microcontroller built on the MIPS32 microAptiv UC core, delivering up to 25 MHz of processing performance from a 64 KB Flash program memory and 8 KB SRAM footprint, housed in a 40-pin UQFN (5x5 mm) package with exposed pad. Designed for space-constrained and battery-driven embedded designs, it integrates rich analog peripherals, configurable serial interfaces, and Microchip's eXtreme Low Power (XLP) technology that drops quiescent current into the sub-microamp region during deep sleep. An MCU (microcontroller unit) is a single-chip computer that combines a CPU core, non-volatile program memory, working RAM, and a mix of analog/digital peripherals on one die. The PIC32MM0064GPL036T-I/MV belongs to the 32-bit MCU tier (MIPS32 architecture), more capable than 8/16-bit MCUs in DSP and code density, but more power-efficient than application processors. Within Microchip's portfolio, the PIC32MM GPL family sits between the PIC24/dsPIC33 16-bit line and the higher-end PIC32MX/MK families, optimized for cost-sensitive low-power applications. Key specifications include a 2.0V to 3.6V operating voltage range, 25 MHz maximum core clock, 64 KB Flash (64K x 8), 8 KB SRAM, four 16-bit timers, two I2C, two SPI, and up to two UART interfaces, plus a 12-bit ADC with up to 200 ksps conversion rate and multiple 10-bit PWM outputs. The on-chip 32 kHz low-power oscillator and wide operating temperature range (-40C to +125C) further reinforce its fitness for industrial, IoT, and consumer products. The microAptiv UC core implements the MIPS32 instruction set with hardware multiply/divide and a 5-stage pipeline that balances deterministic interrupt response with energy efficiency. Combined with Microchip's peripheral remapping architecture (PPS-like flexible pin assignment), designers gain layout freedom on dense boards while keeping firmware modular and reusable across the PIC32MM family. Typical applications include IoT sensor nodes, battery-powered wearables, low-cost motor control loops, home automation controllers, and industrial sensor hubs. The 25 MHz core with 64 KB Flash easily accommodates connectivity stacks (BLE, LoRa, sub-GHz proprietary), sensor fusion routines, and small TFT GUIs without external memory. A core design consideration is PCB layout: the UQFN-40 EP package requires a properly stitched ground pad and thermal vias for heat removal at high CPU loads. Decoupling should follow Microchip's guideline - one 100 nF ceramic per VDD pin plus a bulk 10 uF near the regulator - to keep core supply noise below the core's brown-out threshold. This page synthesizes distributor pricing, drop-in alternatives drawn from the same PIC32MM family, and practical design notes that go beyond the manufacturer datasheet, giving procurement and engineering teams a single decision-ready reference.

PIC32MM0064GPM028-I/ML

PIC32MM0064GPM028-I/ML - 32-bit 25MHz 64KB MCU, USB, 28-QFN | Microchip

The Microchip PIC32MM0064GPM028-I/ML is a 32-bit MIPS32 microAptiv UC core microcontroller running at up to 25 MHz, equipped with 64 KB Flash (with ECC) and 8 KB RAM, housed in a 28-pin QFN (6x6 mm) package with an exposed thermal pad. The device integrates a full-speed USB 2.0 transceiver, multiple low-power modes down to sub-µA currents, and 21 general-purpose I/O lines, making it Microchip's lowest-power and most cost-effective PIC32 family member with USB connectivity. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and programmable peripherals on one piece of silicon. The PIC32MM family sits at the entry level of Microchip's 32-bit PIC portfolio (32-bit MCU -> microcontroller -> embedded processor -> semiconductor), targeting battery-powered and space-constrained designs where every microwatt and square millimeter matters. The PIC32MM GPM sub-family adds USB connectivity, ECC-protected Flash, and a hardware divider to the lower-cost GPL line for designs requiring peripheral connectivity. Key features of this part include 64 KB (64K x 8) of Flash program memory with ECC, 8 KB of SRAM, four DMA channels for efficient data movement, three analog comparators, a 12-bit 1 MSPS ADC with up to 12 channels, three op-amps usable as programmable gain amplifiers, and dedicated USB, UART, SPI, and I2C peripherals. Operating voltage spans 2.0 V to 3.6 V across an industrial -40 °C to +125 °C temperature range, enabling the same part to serve consumer, industrial, and entry-level automotive designs. The CPU core is a 32-bit MIPS32 microAptiv UC implementation with single-cycle hardware multiply/divide and a 5-stage pipeline, achieving 25 MHz / 30 DMIPS performance in a power-efficient footprint. ECC on the Flash array detects and corrects single-bit errors in real time, important for safety-critical USB or sensor applications where transient radiation or electrical noise could otherwise corrupt program memory. Typical applications include low-power USB HID peripherals (mice, keyboards, sensor dongles), wearable health and fitness sensor hubs, IoT edge nodes with USB-C charging, industrial sensor transmitters with USB diagnostics ports, and entry-level consumer electronics requiring 32-bit performance at 8-bit cost points. The exposed thermal pad (EP) variant in QFN-28 aids heat spreading when the device is sustained at full 25 MHz compute load. When designing with the PIC32MM0064GPM028, prioritize the exposed pad PCB layout - it must be soldered to a sufficiently large copper pour (recommended at least 25 mm²) to meet the datasheet's thermal resistance specification of approximately 40 °C/W. USB applications should follow the Microchip USB 2.0 PCB layout guidelines (90-ohm differential, matched length, guard traces) to pass USB compliance testing.
