PIC32MM0032GPL020-I/SS

PIC32MM0032GPL020-I/SS - 32-bit 25MHz 32KB Flash MCU | Microchip

The Microchip PIC32MM0032GPL020-I/SS is a low-power 32-bit MIPS32 microAptiv UC microcontroller with 32KB Flash, 8KB RAM, and a 25MHz core, housed in a 20-pin SSOP package. Designed for the PIC32MM "GPL" low-cost family, it integrates peripherals such as UART, SPI, I2C, 8 PWM channels, 3 timers, 2 comparators, RTCC, and a 12-bit ADC, providing a balanced analog-and-digital feature set in a small outline footprint. The PIC32MM "GPL" family is positioned as Microchip's lowest-power 32-bit MCU line, delivering eXtreme Low Power (XLP) sleep modes down to 500 nA for battery-driven applications. A 32-bit microcontroller (MCU) is a microprocessor-on-a-chip that combines a wide data-path CPU core, on-chip Flash program memory, SRAM data memory, and a rich peripheral set; the PIC32MM family specifically targets migration paths from 16-bit PIC24 and earlier PIC32MX designs into a more power- and cost-efficient 32-bit platform. Key features include 79 CoreMark performance at 25MHz, 1.4 KB data EEPROM, an integrated 12-bit ADC with up to 9 channels, and Core Independent Peripherals (CIPs) that allow hardware-based state machine operation without CPU intervention. The 20-pin SSOP (0.209", 5.30mm body) package supports compact PCB layouts, and the industrial -40C to +85C operating range covers commercial and industrial deployments. Typical applications include IoT sensor nodes, low-power handheld instrumentation, building automation, lighting control, and consumer white-goods user interfaces. The eXtreme Low Power modes make it especially suitable for battery-powered devices where shutdown current is critical. When designing with this MCU, plan GPIO and peripheral assignments carefully because the 20-pin SSOP package limits available I/O compared to the 28- or 36-pin PIC32MM GPL variants. Decoupling must include a 0.1 uF ceramic capacitor on each VDD/VSS pair placed within 5mm of the pins, and unused pins should be configured as outputs to reduce sleep current.

PIC32MM0032GPL020T-I/ML

PIC32MM0032GPL020T-I/ML - 25MHz 32KB Flash 32-bit MCU | Microchip

The Microchip PIC32MM0032GPL020T-I/ML is a 32-bit MIPS32 microAptiv UC-core microcontroller running up to 25 MHz with 32 KB Flash and 8 KB SRAM, housed in a 20-pin QFN 4x4 mm package (tape-and-reel, industrial -40C to +85C). It is part of the PIC32MM GPL "eXtreme Low Power" family, optimized for battery-powered and space-constrained designs where low active and sleep current are critical. A microcontroller (MCU) is a single-chip computer integrating a CPU core, program memory (Flash), data memory (SRAM), and peripherals such as timers, communication interfaces, and analog blocks. The PIC32MM GPL family specifically targets the lowest-power tier of the PIC32 lineup, sitting within the broader hierarchy MCU -> embedded controller -> semiconductor. Its microAptiv core executes the microMIPS instruction set, delivering 79 CoreMark at 25 MHz while keeping dynamic power well below Cortex-M0+ alternatives at the same frequency. Key features include sleep current down to 500 nA in deep sleep (per Microchip PIC32MM GPL family datasheet), 2 UART, 2 SPI/I2S, 2 I2C, 8 PWM outputs, 2 analog comparators, a Real-Time Clock/Calendar (RTCC), multiple 16-bit timers, a 12-bit 200 ksps ADC with up to 9 channels, and a charge time measurement unit (CTMU) for touch and capacitive sensing. The 20-QFN 4x4 mm footprint makes it the smallest package in the PIC32MM GPL line, ideal for wearables, sensor nodes, and remote controls. Architecturally, the device pairs a 2-stage pipelined microAptiv core with single-cycle hardware multiply and a deterministic interrupt controller, giving 32-bit performance at 8-bit MCU code density. Peripheral pin select (PPS) lets designers remap digital functions to any I/O, simplifying PCB layout on a 20-pin device. The integrated 8 MHz FRC and 32 kHz LPFRC oscillators reduce external component count. Typical applications include IoT sensor endpoints, battery-powered medical wearables, low-power wireless sensor nodes, capacitive-touch human-machine interfaces, and compact consumer devices such as remote controls and fitness bands. The 4x4 mm QFN footprint also suits space-constrained industrial modules where 32-bit performance is required but board area is at a premium. When designing with this part, select the correct PPS mapping early, because pin reassignment cannot be done in firmware at runtime in the same way as on larger PIC32MX devices. Decoupling: place a 100 nF X7R directly across VDD/VSS pairs and a bulk 4.7 uF near the package, per Microchip PIC32MM hardware design checklist.

It belongs to the PIC32MM GPL family, Microchip's lowest-power and most cost-effective 32-bit MCU line, delivering 79 CoreMark at 25MHz while supporting eXtreme Low Power (XLP) sleep modes down to 500 nA. The operating voltage spans 2.0V to 3.6V, making it suitable for both battery-powered and 3.3V regulated rails. A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit processor core, program memory (Flash), data memory (SRAM), and programmable peripherals in a single chip. The PIC32MM GPL sits in the broader hierarchy: 32-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. Compared with 8-bit MCUs, a 32-bit core such as the MIPS32 microAptiv UC executes instructions on wider data paths, enabling higher computational throughput per MHz and richer peripheral integration while maintaining deterministic interrupt behavior. Key features of the PIC32MM0032GPL020T-I/SS include 32KB Flash (32K x 8), 8KB SRAM, four 16-bit timers, three MCCP/SCCP capture-compare-PWM modules, three Configurable Logic Cells (CLC) for hardware state-machine offload, 10-bit ADC with 9 channels, two comparators, and a full-speed USB 2.0 device/embedded host controller. The core-independent peripherals (CIPs) let designers offload timing, logic, and signal conditioning from the CPU, lowering active time and overall system energy. The microAptiv UC core implements the microMIPS instruction set, which compresses common instructions to 16 bits while retaining 32-bit MIPS ISA compatibility. This hybrid ISA yields roughly 20% code-density improvement versus pure MIPS32, directly reducing memory footprint and active core time for battery-budgeted IoT nodes. Typical applications include wearable fitness bands, low-cost wireless sensor nodes, remote controls, electronic shelf labels, low-power medical peripherals, and 3.3V industrial sensor front-ends. Its 500 nA sleep current is critical for coin-cell or energy-harvesting designs. When designing with this MCU, leverage the Configurable Logic Cells and MCCP/SCCP modules to implement timing-sensitive functions in hardware; this avoids waking the CPU and substantially extends battery life. Always place a 0.1 uF decoupling capacitor within 5 mm of each VDD pin and follow Microchip's SSOP-20 land-pattern recommendations.

Key features of the PIC32MM0032GPL028T-I/SO include 32 KB Flash program memory, 8 KB SRAM, 25 MHz core clock, 4-channel DMA, 12-bit 200 ksps ADC, and three analog comparators with a 5-bit DAC. It provides up to 21 available I/O pins, multiple serial interfaces (UART, SPI, I2C), and 5 CCP/PWM/OC channels, plus a charge time measurement unit (CTMU) and a hardware real-time clock/calendar (RTCC). Architecturally, the PIC32MM uses the MIPS32 microAptiv UC core (formerly known as M4K) supporting the microMIPS compressed instruction set, giving 79 CoreMark at 25 MHz while keeping code density close to that of 16-bit cores. The wide operating voltage range (2.0 V to 3.6 V) and deep-sleep modes below 1 uA target battery-powered IoT and wearable products. Typical applications include IoT sensor nodes, consumer electronics remote controls, low-power wireless HMI modules, small medical/health monitoring accessories, and battery-backed industrial sensor transmitters. The combination of a 32-bit core and 500 nA sleep makes it well suited for energy-harvesting designs. A key design consideration is that the 28-pin SOIC pinout is shared across the PIC32MM GPL family, allowing PCB reuse among memory-size and package variants (SSOP, QFN). Always confirm supply-voltage decoupling and ADC VREF routing in your layout, since the 12-bit ADC is sensitive to digital switching noise.

PIC32MM0064GPL028-E/SP - 32-bit 25MHz 64KB Flash MCU | Microchip

The Microchip Technology PIC32MM0064GPL028-E/SP is a low-power 32-bit MIPS32 microAptiv UC microcontroller featuring 64 KB Flash, 8 KB SRAM, and 25 MHz core speed, packaged in a 28-pin SPDIP through-hole form factor. Designed for the PIC32MM GPL family, the device delivers 79 CoreMark performance at 25 MHz while consuming only 500 nA in deep sleep, enabling extended battery life in space-constrained designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), and programmable peripherals (ADC, PWM, timers, communication interfaces) on a single silicon die. Within the broader semiconductor taxonomy, an MCU is a subset of microprocessors and embedded processors that prioritizes deterministic real-time control over raw computation. The PIC32MM GPL family positions 32-bit MIPS performance with cost and power consumption that competes directly with mid-range 8-bit and 16-bit MCUs, while retaining the ARM Cortex-M0 ecosystem migration path for users needing code portability. Key features include a 12-channel 12-bit ADC (selectable 10-bit mode), 2 analog comparators, 3 general-purpose timers, 8 PWM channels, and a Real-Time Clock Calendar (RTCC) for timekeeping. The device supports 2.0V to 3.6V operation with on-chip voltage regulation and eXtreme Low Power (XLP) sleep modes that drop quiescent current to 500 nA. Multiple communication peripherals include I2C, SPI, and UART, providing flexible connectivity for sensor and peripheral integration. The 28-pin SPDIP package suits through-hole prototyping, hobbyist projects, and legacy board designs that benefit from socketed or hand-soldered assembly. Technical depth: the MIPS32 microAptiv UC core implements the microMIPS instruction set, a compressed form of MIPS32 that reduces code size by approximately 20-30% compared to standard MIPS32, while retaining deterministic interrupt latency suitable for real-time embedded control. The integrated 8 MHz internal oscillator with PLL provides flexible clocking, and peripheral pin select (PPS) allows remapping of digital functions to optimize PCB routing. The 12-bit ADC achieves 200 ksps with selectable 10-bit low-power mode, and the RTCC continues counting through deep sleep using an external 32.768 kHz crystal. Typical applications include IoT sensor nodes, low-power wireless remote controls, battery-powered instrumentation, HVAC controllers, and consumer electronics with display interfaces. The combination of 64 KB Flash and 8 KB RAM supports substantial application code with comfortable headroom for protocol stacks, while the 12-bit ADC enables precision sensor measurements in industrial and medical monitoring contexts. When designing with this part, verify that the SPDIP-28 footprint matches your mechanical assembly process; for surface-mount designs, the same silicon is available in SOIC-28, QFN-28, and 4x4 mm UQFN packages. The microMIPS core requires an MPLAB XC32 compiler with appropriate optimization flags, and the device is supported by MPLAB X IDE, MPLAB Harmony v3 framework, and the full suite of Microchip code configurators.

PIC32MM0064GPL028-E/SS

PIC32MM0064GPL028-E/SS - 32-bit MCU, 64KB Flash, 28-SSOP | Microchip

The Microchip Technology PIC32MM0064GPL028-E/SS is a 32-bit MIPS32 microAptiv UC microcontroller featuring 64KB of Flash program memory, 8KB of SRAM, and a maximum CPU clock of 25 MHz, housed in a 28-pin SSOP (5.30 mm body width) package. It belongs to the PIC32MM GPL "eXtreme Low Power" (XLP) family, designed for cost-sensitive and space-constrained embedded applications where battery life and active-mode efficiency are both critical. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and a rich set of programmable peripherals. The PIC32MM family sits in the PIC32 hierarchy (32-bit microcontrollers > MIPS-based microcontrollers > XLP low-power family > GPL low-pin-count sub-family) and uses the microAptiv UC core executing the microMIPS instruction set, which compresses common instructions to roughly 30 percent smaller code than MIPS32 mode while retaining full MIPS32 register compatibility for compiled C code. Key differentiating features include sleep current as low as 500 nA in deep sleep, integrated 12-bit ADC with up to 13 channels, two UART, two SPI, two I2C, three 16-bit timers/counters, eight PWM outputs (16-bit resolution), two analog comparators, a Real-Time Clock Calendar (RTCC), and a USB 2.0 full-speed peripheral. The core delivers 79 CoreMark at 25 MHz, balancing performance and energy efficiency. The 28-SSOP package is a 0.65 mm pitch, surface-mount, 5.30 mm body-width plastic package from the SSOP family and is suitable for hand-solderable prototypes as well as high-volume SMT lines. Architecturally, the PIC32MM GPL parts implement a 5-stage pipeline microAptiv core with hardware multiply/divide, single-cycle Flash prefetch, and a peripheral bus that decouples high-speed core traffic from slower peripheral DMA. The deep-sleep power-management unit supports multiple retention options, enabling wake-on-interrupt, RTCC, or external event scenarios typical in IoT sensor nodes. Typical applications for the PIC32MM0064GPL028-E/SS include battery-powered IoT sensor nodes, low-cost USB peripherals, consumer wearables, portable instrumentation, motor and lighting control (8 PWM channels), and home automation endpoints. The combination of USB, RTCC, and rich analog peripherals makes it a strong fit for connected products that must run for months on a single coin cell or AA battery. When designing with this part, ensure the supply is decoupled with a 100 nF plus 10 uF combination near the VDDCORE pins, place the 8 MHz crystal or external reference within 10 mm of the OSC pins to keep clock jitter low, and select the correct VBAT mode register setting if the RTCC is required to survive main-battery removal.

PIC32MM0064GPL028-I/ML - 32-bit 25MHz 64KB Flash XLP MCU | Microchip

The Microchip PIC32MM0064GPL028-I/ML is a 32-bit MIPS microAptiv UC microcontroller running at 25 MHz with 64 KB Flash and 8 KB SRAM, housed in a 28-pin QFN (6x6 mm) package with an exposed pad for thermal dissipation. Part of the PIC32MM GPL XLP (eXtreme Low Power) family, it is engineered for cost-sensitive and power-constrained embedded designs, offering sleep current as low as 500 nA in deep-sleep retention mode and operating from a 2.0 V to 3.6 V supply. A 32-bit microcontroller (MCU) is an integrated computing system that combines a 32-bit CPU core, program and data memory, peripherals, and I/O on a single silicon die. Within the PIC32 family hierarchy, the PIC32MM GPL sub-family targets entry-level, low-power, low-pin-count applications, sitting below PIC32MX and PIC32MZ performance series. The microAptiv core delivers deterministic MIPS32 instruction throughput while integrating DSP extensions and a microMIPS code-compression mode, balancing code density with computational capability for battery-powered products. Key features of the PIC32MM0064GPL028 include 22 general-purpose I/O pins, a 12-bit ADC with up to 11 channels, two analog comparators, and a 10-bit DAC reference output for mixed-signal applications. Communication peripherals: one I2C, two SPI, and two UART modules support sensor and display links. Integrated peripherals include 5-bit and 10-bit configurable PWMs, RTCC with calendar mode, and a charge-time measurement unit (CTMU) for capacitive touch sensing without external ICs, ideal for low-cost touch user interfaces. Architecturally, the device pairs the microAptiv UC core with a single-cycle hardware multiply/divide unit and a four-channel DMA controller, allowing peripheral-to-memory transfers without CPU intervention. The 64 KB self-programmable Flash supports ICSP and runtime updates via the dual-panel Flash array, while the 8 KB SRAM is retained through deep-sleep to preserve application state. Functional-safety features include a configurable LVD, BOR, and a deadman timer for watchdog-style system reset. Typical applications for the PIC32MM0064GPL028-I/ML are wearable fitness bands, remote sensor nodes, low-cost HMI panels with capacitive touch, IoT end-node controllers, and consumer white goods. The combination of low sleep current and a compact 6x6 mm QFN package suits designs where PCB area is constrained and battery life dominates the BOM. Designers favor this MCU when a 32-bit core, modest memory, and peripherals are sufficient and the BOM cost of an external RTC or touch controller would be unacceptable. When designing with the PIC32MM0064GPL028, observe the absolute maximum voltage of 4.0 V on VDD; keep analog and digital grounds tied to a single point near the exposed thermal pad. Decouple VDD with a 100 nF ceramic capacitor placed within 2 mm of the pin, plus a bulk 1 uF to 4.7 uF capacitor on the same net. For reliable ICSP programming, route PGECx/PGEDx as matched-length pairs and avoid routing switching signals beneath them.
