PIC32CM5164LE00100-I/PF Overview
A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory, data memory, and a rich set of programmable peripherals on a single die. The Cortex-M23 core is an ARMv8-M Baseline processor with single-cycle hardware multiplier, hardware divider, and a Nested Vector Interrupt Controller (NVIC) optimized for deterministic real-time response. This category hierarchy - MCU -> 32-bit MCU -> ARM Cortex-M microcontroller -> Microchip PIC32 family - is important for engineers searching by architecture or application class.
Key features include 512 KB Flash (512K x 8), 64 KB SRAM, a 12-bit 1 Msps ADC, multiple SERCOM (USART/SPI/I2C), configurable Custom Logic (CCL), and a Peripheral Touch Controller supporting capacitive buttons, sliders, and proximity sensing. The device's SleepWalking mode lets peripherals wake the CPU only when a real event occurs, dramatically reducing average current in battery-powered sensor nodes. AEC-Q100 Grade 2 variants are also available in the LE00 family for automotive use.
Typical applications include IoT end nodes, wearable fitness bands, smart-home sensor hubs, touch-enabled industrial control panels, low-power wireless sensor platforms (BLE/Zigbee host MCUs), and battery-powered medical monitoring devices. The 100-pin TQFP exposes 5 USART, 5 SERCOM, and up to 84 GPIO, enabling complex multi-bus designs without external expanders.
Designers should plan decoupling carefully: place 100 nF + 4.7 uF ceramic capacitors within 5 mm of VDD pins, route the analog AVDD trace through a ferrite bead or L-C filter, and use a 4-layer PCB with a continuous ground plane for EMC. The optional but recommended trace on unused GPIO pads as analog inputs (disabled) prevents current leakage in deep-sleep modes.

Typical Applications
PIC32CM5164LE00100-I/PF is suitable for 7 applications: Battery-Powered IoT Sensor Node, Wearable Fitness and Health Band, Smart-Home Touch Control Panel, Industrial Touch-Based HMI, Low-Power Wireless Sensor Platform (BLE/Zigbee Host), Battery-Powered Medical Monitoring Device, Capacitive Touch Appliance Control.
Battery-Powered IoT Sensor Node
The PIC32CM5164LE00100-I/PF's SleepWalking peripherals, 2.64 CoreMark/MHz efficiency, and 1.62-3.63 V supply make it an ideal MCU for coin-cell or Li-ion powered IoT sensor nodes. Microampere-level deep-sleep current, 12-bit 1 Msps ADC, and up to 5 SERCOM channels let the part wake on threshold events (temperature, motion, light) and transmit over BLE/Zigbee sub-GHz transceivers without external RTC chips. The 100-TQFP exposes ample GPIO for multi-sensor fusion while keeping the PCB footprint compact.
Recommended
Wearable Fitness and Health Band
The PIC32CM5164LE00100-I/PF is well-suited for wearable fitness bands thanks to its Peripheral Touch Controller (PTC) for capacitive UI buttons and sliders, integrated 12-bit ADC for heart-rate and SpO2 sensor analog front-ends, and ultra-low-power SleepWalking that lets the device idle at microampere currents between sensor samples. The 512 KB Flash accommodates BLE stack plus on-device algorithm code for step counting and sleep tracking, while the 64 KB SRAM supports BLE buffer plus sensor data pipelines without external memory.
Recommended
Smart-Home Touch Control Panel
For wall-mounted smart-home touch panels, the PIC32CM5164LE00100-I/PF combines PTC capacitive touch support (multi-touch capable), enough GPIO to drive LCD displays and relay outputs, and SERCOM peripherals for UART/SPI/I2C connectivity to Wi-Fi/BLE modules. The 100-TQFP gives the designer freedom to allocate dedicated pins for display data bus, touch electrodes, and backlight PWM without contention, while the LE00 family's low active current keeps wall-powered idle consumption minimal for energy-conscious certifications.
Recommended
Industrial Touch-Based HMI
The PIC32CM5164LE00100-I/PF fits industrial HMI panels requiring capacitive touch with glove support, robust -40C to +85C industrial temperature range, and real-time deterministic response. Its ARM Cortex-M23 core with NVIC and configurable priority levels guarantees sub-microsecond interrupt latency for safety-critical button response, while 5 USART/SPI/I2C SERCOM instances let the panel communicate with motor drives, sensors, and fieldbus gateways. The 100-TQFP gives layout flexibility for EMC-compliant routing.
Recommended
Low-Power Wireless Sensor Platform (BLE/Zigbee Host)
As a host MCU for BLE or Zigbee sub-GHz modules, the PIC32CM5164LE00100-I/PF delivers 48 MHz processing to handle TLS/DTLS handshake operations, sensor data preprocessing, and event-driven radio duty-cycling. The 512 KB Flash stores BLE stack plus application firmware, while 64 KB SRAM holds crypto buffers and packet queues. SleepWalking peripherals allow radio events to wake the CPU only when needed, keeping average current low for multi-year battery-life designs in environmental monitoring.
Recommended
Battery-Powered Medical Monitoring Device
The PIC32CM5164LE00100-I/PF suits portable medical monitors (pulse oximeters, blood-pressure cuffs, glucose meters) needing reliable 12-bit ADC accuracy for analog sensor conditioning, deterministic Cortex-M23 interrupt handling for safety timing, and ultra-low-power operation for AAA-cell longevity. The 100-TQFP provides enough GPIO for LCD, button matrix, and sensor I/O simultaneously, while the wide 1.62-3.63 V supply tolerates direct battery connection as cells discharge. Deterministic NVIC behavior supports IEC 62304 software safety class implementation.
Recommended
Capacitive Touch Appliance Control
For kitchen appliances, smart white goods, and HVAC controls, the PIC32CM5164LE00100-I/PF's Peripheral Touch Controller supports robust capacitive touch through thick overlays and glass, including water-rejection algorithms. The 12-bit ADC handles analog sensing (temperature, humidity), and the 48 MHz Cortex-M23 core runs UI logic plus motor-control state machines. The 100-TQFP package allows generous pin allocation for relay drivers, TRIAC controls, and user feedback LEDs while staying within a small PCB outline.

Design Notes
Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD pin and a bulk 4.7 uF ceramic on the main supply rail. Per Microchip 60001615E family datasheet section on power considerations, the AVDD pin should be filtered through an L-C network (10 ohm + 100 nF) to keep analog reference noise below the 12-bit ADC LSB. Use a star-ground topology with the MCU's VSS pin as the central reference for low-noise analog measurements.
The 100-TQFP at 0.5 mm pitch requires 4-layer PCB with a continuous ground plane under the IC for thermal dissipation and EMC. Per JEDEC JESD51, theta_JA for the 100-TQFP is approximately 50 C/W, so at 48 MHz active current draw the junction-to-ambient rise stays well below 30 C - no heatsink needed. Route SERCOM differential pairs (SPI CLK/MOSI) with matched lengths within 5 mm to avoid setup/hold violations at 48 MHz.
Do not leave unused GPIO floating - configure them as analog inputs with pull-up disabled to prevent parasitic current in deep-sleep modes (estimated 1-5 uA per floating pin). Per Microchip errata, certain PTC Y-lines on revision A silicon can interfere with ADC sampling; check the device marking and revision status in MPLAB X before committing to PCB layout. Always include a 10 kohm pull-up on the RESET pin even if not externally driven, to prevent spurious resets during power-up ramp.
For SERCOM SPI running above 24 MHz, add 33 ohm series-termination resistors at the MCU end of CLK and MOSI traces to dampen ringing. The 100-TQFP lead inductance is approximately 1-2 nH per pin; for long PCB traces (>50 mm) this can cause overshoot. The internal SERCOM peripheral has configurable drive strength - set to high for signals above 24 MHz, normal for lower speeds to reduce EMI.
Compliance Information
RoHS and REACH compliance per Microchip product page. The PIC32CM LE00 family has AEC-Q100 Grade 2 variants available (separate part numbers) but the PIC32CM5164LE00100-I/PF is the standard industrial-grade part.
