PIC32MM0016GPL028-I/SS 概述
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit CPU core, Flash program memory, SRAM data memory, and peripherals such as ADCs, timers, and communication interfaces. The PIC32MM family is a low-cost, low-pin-count branch of the broader PIC32 line, optimized for space-constrained and energy-constrained designs. Within Microchip's taxonomy, PIC32MM sits under PIC32 -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor.
Key specifications of the PIC32MM0016GPL028-I/SS include 16 KB (16K x 8) Flash, 4 KB SRAM, a maximum CPU clock of 25 MHz, and operating voltage of 2.0 V to 3.6 V. The -I suffix indicates an industrial temperature range of -40 C to +85 C. The 28-SSOP package provides a compact 5.30 mm footprint suitable for hand-held and IoT devices.
Architecture-wise, the device uses a MIPS32 microAptiv UC core with single-cycle hardware multiply and a 4-stage pipeline, delivering 1.53 DMIPS/MHz. It includes a 12-bit ADC with up to 9 channels, 3 analog comparators, multiple timers, I2C, SPI, UART, and a 6-channel PWM. The peripheral pin select (PPS) feature allows flexible function-to-pin mapping.
Typical applications include IoT sensor nodes, wearable fitness bands, consumer remote controls, battery-operated medical peripherals, low-cost industrial sensors, and smart home edge devices. The wide operating voltage and ultra-low sleep current make it ideal for Energy Harvesting or coin-cell powered designs.
When designing with this MCU, ensure the supply voltage stays within 2.0 V to 3.6 V and that decoupling capacitors are placed close to VDD/AVDD pins. The device supports MPLAB X IDE and XC32 compiler, and JTAG/ICSP programming for development.

典型应用
PIC32MM0016GPL028-I/SS 适用于 6 应用s: IoT Sensor Nodes, Wearable Fitness Bands, Consumer Remote Controls, Battery-Operated Medical Peripherals, Low-Cost Industrial Sensors, Smart Home Edge Devices.
IoT Sensor Nodes
The PIC32MM0016GPL028-I/SS is ideal for IoT sensor nodes requiring long battery life and low power consumption. With sleep currents as low as 500 nA and XLP technology, the device can operate for years on small batteries or energy harvesting sources. The 25 MHz MIPS32 microAptiv UC core provides ample processing power for sensor fusion algorithms, while the integrated 12-bit ADC handles analog sensor readings directly. The 28-SSOP package balances I/O count with compact footprint for space-constrained node designs.
推荐
Wearable Fitness Bands
Wearable fitness bands benefit from the PIC32MM0016GPL028-I/SS combination of low power and small footprint. The 500 nA sleep current extends battery life to multi-week usage, while the 21 GPIO pins interface directly with heart rate sensors, accelerometers, and OLED displays. The 4 KB SRAM is sufficient for short data buffers and protocol stacks. The device operates from a single coin cell or Li-ion battery at 2.0 V to 3.6 V without additional regulators.
推荐
Consumer Remote Controls
Consumer remote controls leverage the PIC32MM0016GPL028-I/SS for its low cost, low power, and integrated peripherals. The UART/SPI interfaces connect directly to RF transmitters like the MICRF112, while the PWM channels drive IR LEDs for universal remote protocols. The 16 KB Flash stores multiple device code libraries and learning remote firmware. Sleep current at 500 nA means a single CR2032 battery can power the remote for years of typical use.
推荐
Battery-Operated Medical Peripherals
Battery-operated medical peripherals such as pulse oximeters, glucose meters, and portable patient monitors benefit from the PIC32MM0016GPL028-I/SS industrial temperature grade and XLP technology. The 12-bit ADC with 9 channels is sufficient for medical sensor signal conditioning, while the MIPS32 core runs sensor algorithms. Operating from 2.0 V to 3.6 V allows direct battery connection, and the low sleep current extends operational life for home-health devices used intermittently.
推荐
Low-Cost Industrial Sensors
Low-cost industrial sensors in factory automation and building management use the PIC32MM0016GPL028-I/SS for reliable operation in harsh environments. The -40 C to +85 C industrial temperature range handles outdoor and factory floor conditions. The 12-bit ADC reads 4-20 mA loop signals or voltage dividers, while UART interfaces connect to RS-485 transceivers for industrial networks. The 25 MHz core runs PID control loops and Modbus RTU protocol stacks in firmware.
推荐
Smart Home Edge Devices
Smart home edge devices such as door/window sensors, motion detectors, and smart switches use the PIC32MM0016GPL028-I/SS for its wireless-friendly low-power profile and integrated peripherals. The 25 MHz core handles BLE/Zigbee stacks or simple proprietary RF protocols, while the ADC monitors battery voltage and sensor inputs. The 28-SSOP package enables PCB designs small enough to fit inside standard wall switch boxes or sensor housings.

关键差异点
- Higher Flash capacity with identical footprint （对比 PIC32MM0016GPL020-I/SS)
- Lower cost than PIC32MK and PIC32MX alternatives （对比 PIC32MK1024GPK064-I/PT)
- Ultra-low sleep current for battery designs （对比 PIC32MX170F256B-I/SP)
设计说明
Decouple VDD and AVDD with 100 nF ceramic capacitors placed within 3 mm of each supply pin. For battery-powered designs, route AVDD through a ferrite bead from VDD to isolate analog noise. The internal LDO and XLP sleep modes drop quiescent current to 500 nA typical, so use a high-efficiency LDO such as MCP1700 for the 3.3 V rail when sourcing from a higher-voltage battery.
Route the ICSP programming pins (PGEC1/PGED1) directly to a 6-pin header with no series resistors in production designs to allow in-circuit programming. Keep the MCLR line short and add a 10 kohm pull-up to VDD; do not leave MCLR floating as the device will not start reliably. Place the 28-SSOP package on a 0.65 mm pitch compatible footprint per JEDEC MO-150 standards.
Do not exceed 3.6 V on any I/O - even momentary overvoltage on ADC pins can damage the device. When using Peripheral Pin Select (PPS), unlock the PPS registers with the IOLOCK mechanism before configuration or the writes will be silently ignored. Avoid using the JTAG pins (TCK/TMS/TDO/TDI) as GPIO without first disabling JTAG in the configuration bits, otherwise JTAG debug will fail.
