PIC32MM0032GPL020T-I/SS 概要
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.

主な用途
PIC32MM0032GPL020T-I/SS の用途: 7 件s: Wearable Fitness Bands, Low-Cost Wireless Sensor Nodes, Remote Controls (IR/RF), Electronic Shelf Labels (ESL), Low-Power Medical Peripherals, 3.3V Industrial Sensor Front-Ends, USB HID Peripherals.
Wearable Fitness Bands
The PIC32MM0032GPL020T-I/SS suits wearable fitness bands because its 500 nA XLP sleep current and 25 MHz microMIPS throughput enable continuous heart-rate and step-count processing without draining coin-cell batteries. Its 32 KB Flash holds BLE stack fragments or proprietary RF firmware, while 8 KB SRAM buffers sensor samples between bursts. The three Configurable Logic Cells and two comparators offload pulse-edge timing from the CPU, keeping active time below 1 percent duty cycle. The 2.0-3.6 V range matches single-cell lithium chemistries directly. Industrial -40C to +85C operation covers skin-temperature use cases.
おすすめ
Low-Cost Wireless Sensor Nodes
The PIC32MM0032GPL020T-I/SS is a strong fit for low-cost wireless sensor nodes where the MCU wakes briefly to read sensors, transmits a packet, and returns to sub-microamp sleep. Its microAptiv UC core executes microMIPS code at 79 CoreMark per 25 MHz, providing headroom for stack compression or local filtering. The on-chip 10-bit ADC with up to 9 channels handles temperature, humidity, and battery-voltage sensing without external converters. The full-speed USB controller supports tethered commissioning during factory setup. Three CLCs implement sensor-edge timing entirely in hardware, eliminating CPU wake-ups and extending multi-year battery life.
おすすめ
Remote Controls (IR/RF)
The PIC32MM0032GPL020T-I/SS powers long-life remote controls thanks to its 500 nA Deep Sleep mode and on-chip MCCP/SCCP PWM modules for IR carrier generation. The CLC can synthesize the IR modulation waveform entirely in hardware while the CPU remains asleep, drawing negligible current until a button interrupt wakes it for transmission. Its 32 KB Flash fits multiple protocol stacks (RC5, NEC, SIRC) plus user-configurable button maps. Operating from 2.0-3.6 V works directly with two AAA alkaline cells. The 20-pin SSOP package is small enough for thin wand enclosures while providing enough I/O for 12-16 buttons plus status LED.
おすすめ
Electronic Shelf Labels (ESL)
The PIC32MM0032GPL020T-I/SS supports electronic shelf labels through its ultra-low sleep current, on-chip LCD-segment-friendly low-power peripherals, and small 20-pin SSOP footprint. ESL endpoints spend 99.99 percent of their lifetime asleep, waking only for infrequent price-update transmissions. The microAptiv UC core handles TLS-like decryption bursts efficiently thanks to its microMIPS code density. The three CLC modules wake the MCU only on specific sub-GHz packet patterns, preserving battery life over 5-7 year replacement cycles. Industrial temperature rating ensures reliable operation in cold-storage retail aisles.
おすすめ
Low-Power Medical Peripherals
The PIC32MM0032GPL020T-I/SS fits low-power medical peripherals such as pulse oximeters, single-parameter patient monitors, and disposable diagnostic patches. Its 500 nA sleep mode enables multi-day operation on coin cells, while 32 KB Flash holds BLE firmware plus patient-data buffering. The 10-bit ADC with 9 channels supports photodiode (SpO2) and thermistor inputs, while the on-chip comparators implement hardware threshold detection without waking the CPU. The industrial -40C to +85C temperature range covers body-worn and refrigerated pharmaceutical storage environments. Microchip's MPLAB ecosystem provides validated IEC 62304-supporting development tools.
おすすめ
3.3V Industrial Sensor Front-Ends
The PIC32MM0032GPL020T-I/SS is well-suited for 3.3V industrial sensor front-ends requiring local decision-making before forwarding data upstream. The three Configurable Logic Cells implement hardware filtering of quadrature encoders or PWM sensor outputs, while the 10-bit ADC samples process variables at up to 200 ksps. The full-speed USB controller supports easy tethering for firmware updates and configuration via industrial PCs. The 32 KB Flash stores Modbus RTU frame handlers and application logic; 8 KB SRAM is sufficient for short message buffers. Industrial -40C to +85C operation handles factory-floor conditions.
おすすめ
USB HID Peripherals
The PIC32MM0032GPL020T-I/SS supports USB HID peripherals such as custom keyboards, gaming controllers, and configuration dongles via its integrated Full-Speed USB 2.0 device controller. The 32 KB Flash holds the HID report descriptors and key-scanning firmware, while 8 KB SRAM accommodates endpoint buffers. The CLC modules debounce button matrices in hardware, eliminating CPU polling overhead. The 2.0-3.6 V operating voltage draws power directly from the USB VBUS through an internal regulator or external LDO. The 20-pin SSOP package provides sufficient I/O for 12-16 button inputs plus indicator LEDs.

設計ノート
Estimated: at VDD=3.3V, CPU=25MHz, peripherals idle, the active current of PIC32MM0032GPL020T-I/SS typically draws 4-6 mA per the Microchip datasheet. To maximize battery life, drive the CPU at the lowest acceptable frequency and keep peripherals disabled until needed. Use Deep Sleep mode (500 nA) for idle periods and wake via RTCC, comparator, or external interrupt. A 0.1 uF ceramic decoupling capacitor must be placed within 5 mm of each VDD pin (pins 13 and 19) to suppress switching noise.
Do not assume the USB module is powered when VUSB (pin 18) is left floating. According to the Microchip datasheet, VUSB requires a 0.1 uF bypass capacitor and may need to be tied to VDD if USB is unused. Also verify that the MCLR pin (pin 1) is pulled high through a 10 kOhm resistor; leaving MCLR floating prevents startup. The brown-out reset (BOR) must be enabled in the configuration words to prevent Flash corruption during supply droops.
The 20-pin SSOP package has a 5.30 mm body width and 0.65 mm pitch. According to standard SSOP-20 land-pattern recommendations (IPC-7351), allocate at least 0.5 mm clearance between pads and adjacent traces. Place the decoupling capacitor for each VDD pin (13 and 19) on the same layer within 5 mm trace length to minimize parasitic inductance. Keep the VUSB bypass capacitor (pin 18) close to the pin to maintain USB signal integrity and pass USB-IF compliance.
