PIC32CM2532LS60100-I/PF Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and a rich set of peripherals (timers, ADC, communication controllers, GPIO) into one package. In the broader taxonomy, the PIC32CM2532LS60100-I/PF sits within Cortex-M23 -> ARM Cortex-M microcontroller -> 32-bit MCU -> microcontroller -> integrated circuit -> semiconductor. The Cortex-M23 core is the smallest and most energy-efficient ARMv8-M Baseline implementation, providing a hardware multiplier, hardware divider, NVIC, and optional Memory Protection Unit while preserving Thumb/Thumb-2 instruction efficiency.
Key features of this device include: 48 MHz max CPU clock, 256 KB Flash, 32 KB SRAM, 2.0 V to 3.63 V operating voltage (LS60 variant), integrated Peripheral Touch Controller (PTC) for capacitive touch, SleepWalking peripherals that wake only the necessary logic blocks, multiple SERCOM (configurable serial communication) interfaces, a 12-bit ADC, and a hardware cryptographic accelerator supporting AES, SHA, and secure boot. Security extensions include true random number generation, secure firmware update, and immutable boot.
Architecturally, the PIC32CM2532LS60100-I/PF combines an event-based peripheral fabric with SleepWalking DMA-style wake logic, allowing the core to remain in deep sleep while peripherals process events and trigger wake-ups only when meaningful thresholds are crossed. This makes it one of the most power-efficient Cortex-M23 MCUs in its class.
Typical applications include secure IoT end nodes, capacitive touch user interfaces, smart home sensors, wearables, medical monitoring peripherals, and industrial control panels where both low power and security are required.
When designing with this part, ensure your toolchain is MPLAB X IDE / MPLAB Harmony 3 based, and verify that your PCB layout respects the TQFP-100 thermal pad and decoupling guidance. Pinout compatibility with the non-secure PIC32CM2532LE00100-I/PF allows easy upgrade paths.

Typical Applications
PIC32CM2532LS60100-I/PF is suitable for 6 applications: Secure IoT End Nodes, Capacitive Touch HMI, Wearable Health Monitoring, Smart Home Sensors, Industrial Control Panels, Medical Monitoring Peripherals.
Secure IoT End Nodes
The PIC32CM2532LS60100-I/PF is engineered for secure IoT end nodes requiring on-chip cryptography and immutable boot. Its hardware AES/SHA engine, true random number generator, and secure boot ROM enable PSA Certified Level 1 designs without an external secure element. Running Cortex-M23 at 48 MHz with 256 KB Flash and 32 KB SRAM, it has ample headroom for TLS 1.3 stacks, MQTT-SN, and Matter commissioning payloads. SleepWalking peripherals allow the device to remain connected to a Thread/Zigbee/BLE radio while consuming only microamps until a meaningful wake event arrives.
Recommended
Capacitive Touch HMI
With the integrated Peripheral Touch Controller (PTC), the PIC32CM2532LS60100-I/PF enables robust capacitive touch user interfaces for home appliances, industrial panels, and consumer products. The PTC supports mutual-capacitance and self-capacitance scanning with driven shield plus, allowing water-tolerant and glove-compatible operation. Combined with SleepWalking DMA-style wake logic, the MCU can scan a touch matrix at sub-milliwatt average current, only waking the core on confirmed touch. The 256 KB Flash accommodates Microchip's QTouch library and a touch-optimized GUI.
Recommended
Wearable Health Monitoring
The PIC32CM2532LS60100-I/PF suits wearable health monitors such as heart-rate patches, smartwatches, and continuous glucose meters because it combines ultra-low-power SleepWalking peripherals with a Cortex-M23 core capable of running sensor-fusion DSP. Its 2.0 V to 3.63 V supply range matches single-cell Li-ion chemistries, while its integrated 12-bit ADC reads bio-potential signals without an external analog front end. Hardware security protects PHI data at rest and in OTA firmware updates, meeting HIPAA-class device expectations.
Recommended
Smart Home Sensors
The PIC32CM2532LS60100-I/PF is a strong fit for battery-powered smart home sensors like door/window contacts, occupancy detectors, and climate sensors. Its deep-sleep current with RAM retention and RTC is in the microamp range, allowing multi-year operation from a CR2032 coin cell. Hardware AES and TRNG secure the wireless commissioning, preventing replay attacks and unauthorized pairing. The Cortex-M23 core wakes in microseconds to process sensor data and transmit via Thread, Zigbee, or proprietary sub-GHz radios.
Recommended
Industrial Control Panels
For industrial control panels, the PIC32CM2532LS60100-I/PF provides deterministic Cortex-M28 execution up to 40 MHz with hardware crypto for authenticated fieldbus commands. The 100-pin TQFP exposes multiple SERCOM channels (configurable as UART/SPI/I2C), enough to drive RS-485 Modbus, SPI displays, and I2C sensor backplanes simultaneously. Its industrial -40C to +85C operating range suits factory floor enclosures, and its secure boot prevents unauthorized firmware injection into mission-critical assets.
Recommended
Medical Monitoring Peripherals
The PIC32CM2532LS60100-I/PF is well matched to medical monitoring peripherals such as portable pulse oximeters, spirometers, and connected thermometers. Its Cortex-M28 core can run the necessary signal-processing algorithms while the hardware crypto engine protects patient data exchanged over BLE or USB. The integrated 12-bit ADC reads analog sensor outputs directly, and the SleepWalking peripherals enable multi-day battery life on a single charge. PSA Certified Level 1 readiness eases the regulatory pathway for IEC 62443-style connected medical designs.

Key Differentiators
- On-chip hardware cryptography with secure boot (vs PIC32CM2532LE00100-I/PF)

- Larger SRAM buffer for richer firmware (vs PIC32CM2532LS60064-I/PF)
Design Notes
Estimated: at 48 MHz active current is approximately 70 uA/MHz from VDDIO, giving ~3.4 mA core current when fully active; in deep-sleep with RTC running the part drops to single-digit microamps per the Microchip PIC32CM LS60 family datasheet. Place a 100 nF decoupling capacitor within 2 mm of every VDDIO pin and a single 4.7 uF bulk capacitor at the VDDANA pin. For battery designs using SleepWalking, ensure the wake source uses an RTC alarm or PTC touch event rather than the ADC to minimize average current draw.
The TQFP-100 package has an estimated theta_JA of approximately 50 C/W on a 2-layer JEDEC test board. Estimated: at 3.3 V VDDIO, 48 MHz operation, and ~3.4 mA active core current, the die dissipates roughly 11 mW, giving a junction temperature rise of 0.6 C above ambient - well within the 125 C maximum. For continuous ADC-intensive operation, add a small copper pour under the exposed thermal pad to share heat between die and PCB. Industrial designs at +85 C ambient still have ~40 C margin.
Place decoupling capacitors as close as possible to each VDDIO/VVDDANA pin; use 100 nF X7R ceramic for each supply pin and a single 4.7 uF X5R bulk capacitor near the package. Route the PTC touch lines with grounded shield traces or driven shield plus signals to suppress moisture-induced false touches. For USB applications using PA24/PA25, place the 48 MHz crystal within 5 mm of PA18/PA19 and keep the clock trace over a continuous ground plane; do not route the crystal traces near PTC sense lines.
Do not apply voltage above 3.63 V to any VDDIO pin or above 3.63 V to VDDANA; permanent damage may result. Ensure unused GPIO pins are configured as outputs driven low, or as inputs with the internal pull-up enabled - floating inputs can inject leakage current during deep-sleep and increase power consumption by tens of microamps. When using the Peripheral Touch Controller, disable the PTC during debug to avoid spurious wake-ups; refer to the MPLAB Harmony 3 PTC configuration documentation. The LS60 family has a 2.0 V minimum VDD, so designs that previously used the LE00 family at 1.8 V nominal must add a boost converter or upgrade to a wider-VIN LDO.
Compliance Information
RoHS and REACH compliant per Microchip product page. Industrial temperature grade -40C to +85C. Not AEC-Q100 qualified - choose the PIC32CM2532LS60100-E/PF extended-temperature variant for harsh environments.
