Référence : PIC32CM2532LS60064T-I/PT ✓ ActifPIC32CM2532LS60064T-I/PT Présentation
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, and configurable peripherals such as ADCs, timers, communication controllers, and GPIOs. The PIC32CM LS family belongs to the broader category of 32-bit microcontrollers -> ARM Cortex-M microcontrollers -> embedded processors -> integrated circuits, and is positioned in the system hierarchy between simple 8-bit MCUs and high-performance application processors. By integrating Cortex-M23 cores with TrustZone-M security and advanced peripherals, these MCUs reduce BOM cost and PCB footprint in IoT, industrial sensing, and human-machine interface (HMI) designs.
Key features include hardware-based Arm TrustZone-M security, a touch-capable Peripheral Touch Controller (PTC), SleepWalking peripherals for event-driven wake-up, multiple SERCOM-based serial interfaces, a 12-bit ADC, and on-chip op-amps and DAC. The wide operating voltage range of 1.62V to 3.63V supports battery-powered designs, while the integrated voltage regulator and on-the-fly peripheral gating minimize active and standby power consumption to support multi-year battery life in IoT endpoints.
Architecturally, the device couples an ARM Cortex-M23 core with Microchip's proprietary SleepWalking and Event System peripherals, allowing I/O events to wake the CPU without continuous polling. TrustZone-M isolation provides hardware-rooted secure boot, secure key storage, and CryptoCell-like accelerator hooks for AES/SHA, enabling designers to meet PSA Certified Level 1 / 2 security requirements without external secure elements.
Typical applications include secure IoT sensor nodes, low-power wireless HMI controls, capacitive touch user interfaces, smart meters, and battery-powered industrial edge devices. The TQFP-64 footprint and -40C to +85C industrial temperature range suit harsh-environment deployments.
When designing, prioritize SleepWalking configuration to minimize wake-up overhead, place the 0.1uF decoupling capacitor on each VDD pin within 3 mm, and use TrustZone-M secure/non-secure call gates to isolate credential handling.

Applications typiques
PIC32CM2532LS60064T-I/PT convient pour 6 applications: Secure Battery-Powered IoT Sensor Nodes, Capacitive Touch HMI Controls, Smart Metering Endpoints, Industrial Edge Sensor Hubs, Wearable Health Monitoring Devices, Building Automation and Lighting Controls.
Secure Battery-Powered IoT Sensor Nodes
The PIC32CM2532LS60064T-I/PT is purpose-built for secure battery-powered IoT sensor nodes that must run for years on a single cell. Its Cortex-M23 core combines with TrustZone-M hardware isolation for PSA Certified Level 1/2-ready secure boot and key storage, while SleepWalking peripherals keep the device in sub-uA Sleep mode until sensor events occur. Operating from 1.62V to 3.63V directly from a single Li-ion or 2x AA battery stack eliminates the need for an external LDO. The 256 KB Flash supports OTA update images plus application code, and the Event System routes ADC and SERCOM triggers without waking the core. Compared to a discrete secure-element + Cortex-M0 design, the LS60064 reduces BOM cost and PCB area by integrating both into a single TQFP-64 package.

Capacitive Touch HMI Controls
The PIC32CM2532LS60064T-I/PT integrates Microchip's Peripheral Touch Controller (PTC), supporting self- and mutual-capacitance touch sensing for buttons, sliders, and wheels without an external touch IC. The Cortex-M23 core runs touch acquisition and gesture processing, while 256 KB Flash holds capacitive-touch libraries and custom UI logic. SleepWalking on the PTC keeps idle power below 50 uA while continuously scanning for finger presence, so battery-powered HMI products can deliver multi-year lifetimes. The TQFP-64 package exposes enough GPIOs for typical 12-key keypads or 5-inch slider/wheel interfaces. Compared to a separate touch IC + host MCU architecture, the integrated PTC approach reduces BOM cost and BOM count.
Recommandé
Smart Metering Endpoints
The PIC32CM2532LS60064T-I/PT suits smart electricity, gas, and water metering endpoints requiring secure metrology data and decade-long battery life. The Cortex-M23 + TrustZone-M combination supports signed firmware updates and tamper detection, while the 12-bit ADC captures metrology signals with adequate resolution for billing-grade measurement (calibrated with external references for higher precision). SleepWalking peripherals let the MCU stay in deep Sleep until metering events occur, keeping average current draw in the single-digit uA range. The industrial -40C to +85C temperature range covers outdoor and basement installations. Compared to discrete metrology AFE + MCU designs, the integrated approach reduces component count and improves reliability.
Recommandé
Industrial Edge Sensor Hubs
The PIC32CM2532LS60064T-I/PT is well-suited for industrial edge sensor hubs that aggregate multiple sensor inputs (temperature, pressure, flow) and forward data over RS-485, CAN, or LoRa. The Cortex-M23 at 48 MHz provides enough headroom for sensor-fusion algorithms and protocol stacks, while SERCOM peripherals handle UART, SPI, and I2C simultaneously. The Event System enables deterministic sensor sampling without CPU intervention, reducing jitter in time-stamped telemetry. TrustZone-M hardware isolation protects OTA credentials and authentication keys in industrial settings where physical access may be feasible. Compared to a Cortex-M0+ hub, the M23's Thumb-2 instruction set yields roughly 30% better code density for protocol stacks.
Recommandé
Wearable Health Monitoring Devices
The PIC32CM2532LS60064T-I/PT fits wearable health monitoring bands and patches where battery life, low power, and small PCB area dominate. The Cortex-M23 core processes heart-rate, SpO2, and motion data at modest MIPS while SleepWalking peripherals keep current draw below 50 uA between sensor updates. TrustZone-M isolates personal health information (PHI) from non-secure application code, supporting HIPAA-style data-handling requirements in firmware. The 1.62V-3.63V supply range allows direct operation from a single Li-Po cell without external regulation. Compared to a discrete BLE SoC + sensor hub, the integrated approach reduces PCB area by roughly 40% in typical wearable reference designs.
Recommandé
Building Automation and Lighting Controls
The PIC32CM2532LS60064T-I/PT suits building automation controllers such as KNX nodes, DALI lighting controllers, and HVAC zone controllers where secure firmware, low standby power, and capacitive touch user interfaces converge. The integrated PTC supports glass-overlay capacitive keypads typical of modern lighting control panels, while Cortex-M23 + TrustZone-M provide tamper-resistant commissioning credentials. SleepWalking peripherals allow battery-backed wall switches to operate for years on a coin cell. The wide supply range accommodates 24V building bus systems with appropriate external regulation. Compared to discrete touch IC + Cortex-M0 designs, integration reduces BOM cost and improves EMI immunity on long cable runs.

Principaux différenciateurs
- Integrated Peripheral Touch Controller (PTC) without external touch IC (vs PIC32CM2532LS00064)
- TrustZone-M hardware isolation for PSA Certified security (vs PIC24HJ64GP510T-I/PT (PIC24 MIPS core))
- SleepWalking peripherals keep MCU in sub-uA Sleep until sensor events (vs Generic Cortex-M0+ MCU)
Notes de conception
Place a 0.1 uF decoupling capacitor within 3 mm of each VDD pin (pins 6, 18, 28, 42, 53) and a bulk 4.7 uF capacitor on the supply rail. The integrated LDO regulates the internal core domain; ensure VDD stays above 1.62V during Sleep transitions. For battery-powered designs, use SleepWalking mode to keep average current below 10 uA while still monitoring ADC and SERCOM inputs.
The TQFP-64 package has a typical theta_JA around 50 C/W on a 4-layer PCB. At maximum active CPU load (48 MHz, peripherals enabled) the device dissipates well below 100 mW, so passive cooling is sufficient. For extended-temperature (-40C to +85C) industrial installations, add thermal vias under the exposed pad to improve heat spreading to inner copper planes.
Route the SWDIO (PA30) and SWCLK (PA31) signals with short, parallel traces and a ground return path to preserve debug signal integrity. Keep the RESET trace away from switching nodes and add a 10 kohm pull-up to VDD. For capacitive touch (PTC) applications, route PTC channels on the top layer only and avoid crossing them with noisy digital traces; add a hatched ground pour beneath the touch sensor area for stable baseline capacitance.
Estimated: TrustZone-M secure/non-secure call gates add 5-15 cycles of overhead per crossing; if you call secure functions inside a high-frequency ISR, secure-call latency can dominate execution time. Place frequently-called secure functions in the non-secure callable region or batch secure operations. Also, the PTC requires calibration to PCB trace capacitance - do not skip the touch library's self-calibration step during firmware initialization, or touch sensitivity will drift with temperature.
