PIC32CM5164LS60064-I/5LX Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, volatile memory (SRAM), non-volatile memory (Flash), and a rich set of peripherals such as timers, communication interfaces, ADC/DAC, and GPIO. Within the broader semiconductor hierarchy, an MCU sits between a microprocessor (MPU, which requires external memory and peripherals) and a system-on-chip (SoC, which adds application-specific accelerators). The Cortex-M23 core specifically targets low-power, deterministic embedded applications that benefit from the ARMv8-M baseline architecture, including TrustZone for ARMv8-M and the Cortex-M23 instruction subset, while preserving bit-band-free deterministic interrupt latency.
Key features of the PIC32CM5164LS60064 include an integrated Trust Platform ATECC608 secure element, Arm TrustZone for hardware-isolated secure/non-secure firmware domains, immutable root-of-trust secure boot, innovative SleepWalking peripherals that allow I/O and analog blocks to operate autonomously while the CPU remains asleep, industry-leading water-tolerant touch sensing, on-chip op amps, and a 12-bit ADC with up to 1 Msps conversion rate. The device family also integrates DAC, comparators and zero-crossing detectors.
Architecturally, the LS60 variant extends the lower-power LE/LS00 line with the embedded ATECC608 secure element and full TrustZone support, enabling secure key storage, ECDSA/Boot verification, and tamper detection. Compared with Cortex-M0+ designs, the M23 adds hardware divide, faster interrupt entry, and deterministic Thumb-only instruction execution, making this part well-suited to IoT edge nodes, secure authentication endpoints, and human-machine-interface panels.
Typical applications include secure IoT end nodes, home and building automation controllers, smart appliances with capacitive touch HMIs, wireless sensor hubs pairing with external radios, low-power medical wearables, and industrial HMI panels. When designing with this part, allocate the 64-pin VQFN land pattern early because the 5LX variant is the largest 64-pin option in the family and a smaller 48-pin VQFN (U5B) or 64-pin TQFP (PT) layout would require pin remapping.

Typical Applications
PIC32CM5164LS60064-I/5LX is suitable for 6 applications: Secure IoT Edge Nodes, Smart Home and Building Automation Hubs, Capacitive Touch HMI Panels, Battery-Powered Wearable Medical Devices, Industrial Sensor and Actuator Nodes, Secure Wireless Sensor Hubs.
Secure IoT Edge Nodes
The PIC32CM5164LS60064-I/5LX is engineered for secure IoT edge nodes where hardware-rooted authentication, signed firmware updates, and tamper detection are mandatory. Its integrated ATECC608 secure element stores private keys in hardware and performs ECDSA verification without exposing secrets to firmware, while Arm TrustZone isolates the secure bootloader and key provisioning code from the application. With 48 MHz Cortex-M23 performance, the device handles TLS handshakes, sensor pre-processing, and SleepWalking peripheral tasks that let the CPU remain asleep while the ADC, I2C, and touch peripherals operate autonomously. The 64 KB SRAM is sufficient for a TLS stack plus an mbedTLS or WolfSSL client, and 512 KB Flash holds multiple signed images for A/B firmware update schemes.
Recommended
Smart Home and Building Automation Hubs
The PIC32CM5164LS60064-I/5LX fits smart-home and building-automation hubs that aggregate Zigbee, BLE, or Wi-Fi sensor traffic and execute local rules. Its Cortex-M23 core runs control loops for HVAC, lighting, and occupancy detection at 48 MHz with deterministic interrupt latency, while the 64-pin VQFN exposes 50+ GPIO for keypad scanning, status LEDs, and relay drivers. Water-tolerant capacitive touch support means the part can replace mechanical buttons behind glass or plastic overlays in wall-mounted thermostats. TrustZone isolates the proprietary hub firmware from third-party Matter/Thread stacks, and SleepWalking peripherals wake the CPU only on a meaningful user action, reducing idle power below 10 uA for battery-backed thermostats.
Recommended
Capacitive Touch HMI Panels
The PIC32CM5164LS60064-I/5LX suits capacitive touch HMI panels in appliances, industrial equipment, and consumer products. Its mTouch peripheral supports water-tolerant touch, allowing reliable operation when the front panel is wet or has condensation - critical for outdoor kiosks and kitchen appliances. The on-chip 12-bit ADC handles slider and wheel decoding at up to 1 Msps, while the integrated op amps condition sensor signals without external components. Combined with the device's 512 KB Flash and 64 KB SRAM, designers can implement complex gestures, multi-touch decoding, and on-device UI logic on a single chip, reducing BOM cost in coffee machines, washing machines, and elevator control panels.

Battery-Powered Wearable Medical Devices
The PIC32CM5164LS60064-I/5LX targets battery-powered wearable medical devices where low power and deterministic Cortex-M23 performance must coexist with security. SleepWalking peripherals let the MCU monitor heart rate, SpO2, or motion sensors autonomously and wake the CPU only when a threshold is crossed, achieving multi-month coin-cell battery life. TrustZone isolates the medical firmware from companion mobile-app communication stacks, while the embedded ATECC608 supports secure pairing with hospital gateways and HIPAA-compliant audit trails. The industrial -40C to +85C temperature range covers body-worn and skin-adjacent applications, and the small 9x9 mm VQFN footprint allows PCB layouts small enough for wristbands and adhesive patch devices.
Recommended
Industrial Sensor and Actuator Nodes
The PIC32CM5164LS60064-I/5LX serves industrial sensor and actuator nodes in factory automation, building management, and process-control systems. Its Cortex-M23 core runs deterministic control loops at 48 MHz with 1.03 DMIPS/MHz, while the 12-bit ADC, op amps, and comparators handle 4-20 mA analog inputs and threshold detection directly on-chip. TrustZone and the embedded ATECC608 secure element enable secure field provisioning and signed firmware updates required for IEC 62443 compliance, while SleepWalking peripherals keep the node below 50 uA idle for Energy Harvesting or battery-powered installations. The 64-pin VQFN (5LX) package exposes enough GPIO to drive relays, optocouplers, and isolated RS-485 transceivers from a single chip.
Recommended
Secure Wireless Sensor Hubs
The PIC32CM5164LS60064-I/5LX integrates well as the host MCU in wireless sensor hubs that pair with external sub-GHz, BLE, or LoRa radio modules. Its Cortex-M23 core at 48 MHz and 64 KB SRAM run a small RTOS plus radio stack concurrently, while 512 KB Flash holds Over-the-Air update images and configuration data. TrustZone and ATECC608 support secure join procedures for protocols such as LoRaWAN, Zigbee, or BLE Mesh, protecting network keys from firmware extraction. The 50+ GPIO on the 64-pin VQFN enable direct bus connections to SPI-based radio modules and interrupt routing, while SleepWalking peripherals let the hub scan sensors without waking the radio or core unnecessarily.

Design Notes
The PIC32CM5164LS60064-I/5LX operates from 2.0V to 3.63V. For battery applications, take advantage of SleepWalking peripherals: configure the ADC, I2C, or touch peripheral to monitor external events autonomously while the CPU remains in BACKUP or OFF mode. Per the PIC32CM LS60 family data sheet (60001615E), wake-up time from BACKUP is typically 1.2 ms with full SRAM retention below 1.5 uA. Always include a 1 uF decoupling capacitor on each VDD pin plus a 100 nF high-frequency bypass placed within 2 mm of the IC.
The 64-pin VQFN (5LX) package has an exposed thermal pad (EPAD) that must be soldered to a 5x5 mm copper pour on the top layer and stitched to the inner ground plane with at least eight thermal vias (0.3 mm drill, 0.5 mm pitch). According to Microchip soldering profiles for VQFN packages, follow the JEDEC J-STD-020 reflow profile with peak temperature 245C for lead-free assembly. Keep high-speed SERCOM traces length-matched within 0.5 mm and route them over an unbroken reference plane to maintain signal integrity on SPI and I2C peripherals.
For capacitive touch performance, isolate each touch sensor pad with a hatched ground pour separated by at least 0.5 mm to prevent false touches. Water-tolerant touch tuning requires careful PCB stack-up: use a 0.8 mm to 1.6 mm overlay (glass or plastic) and follow Microchip application note AN2934 for sensor layout. Route analog op-amp outputs on a separate layer with a quiet analog ground island that connects to the digital ground at a single point near the IC GND pins.
Estimated: based on a typical 48 MHz active current of about 7 mA from the family data sheet, and a typical VDD of 3.3V, a 3-volt Li coin cell (CR2032, 220 mAh) supplies roughly 11 hours of continuous active runtime. To extend lifetime, ensure firmware puts the CPU in SleepWalking or BACKUP mode whenever possible and disables unused SERCOM peripherals via the PMUX register. Avoid leaving the SWD pins floating in production: route them to a test pad or pull-up to prevent accidental reset or debug-entry glitches.
Compliance Information
RoHS compliant and lead-free per Microchip product page. I-grade (industrial) temperature range -40C to +85C; AEC-Q100 automotive qualification is NOT available on this part. For automotive applications consider PIC32CM variants explicitly labeled as automotive grade.
