PIC32CM5164LS60100-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 (ADC, timers, communication controllers). The PIC32CM LS60 belongs to the ultra-low-power Cortex-M23 class, optimized for battery-powered IoT endpoints that need deterministic real-time response plus cryptographic identity for authentication, secure firmware update, and anti-cloning. Within the hierarchy: MCU -> embedded microcontroller -> 32-bit ARM MCU -> Cortex-M23 -> Microchip PIC32CM family.
Key features include the integrated ATECC608 secure element (hardware ECC/NIST P-256, secure key storage, ECDH/ECDSA), hardware touch support for capacitive button/slider interfaces, a 12-bit 1 MSPS ADC, two 16-bit DAC channels, four SERCOM-style serial interfaces configurable as UART/SPI/I2C, and a Smart Analog peripheral block. The on-chip Memory Protection Unit (MPU) and TrustZone combine to enforce firmware isolation between secure and non-secure code regions.
The LS60 architecture also embeds a SleepWalking peripheral event system, Event System interconnect, and an ultra-low-power RUN/IDLE/STANDYB/STOP/RETENTION/RESET sleep modes family that enables sub-microamp current consumption during duty-cycled sensing, which is critical for coin-cell IoT nodes.
Typical applications include secure IoT sensor nodes with authenticated cloud onboarding, capacitive touch user interfaces for white goods and locks, secure medical wearables with encrypted patient data, smart-metering edge nodes, and asset trackers with secure boot and over-the-air firmware updates. Industrial HMI and home-automation keypads also benefit from the integrated touch engine and ATECC608 identity.
Designers should budget enough PCB area for a 100-pin TQFP at 14x14 mm (0.5 mm pitch), plan decoupling (100 nF close to each VDD pair plus bulk 4.7 uF), and reserve I/O for the integrated touch channels to fully leverage the MCU's differentiators. Carefully review the secure-element I2C lines - they must remain reachable from the host controller to provision credentials during manufacturing.

Typical Applications
PIC32CM5164LS60100-I/PF is suitable for 6 applications: Secure IoT Sensor Node, Capacitive Touch User Interface, Smart Metering Edge Node, Secure Wearable Medical Device, Smart Lock and Access Control, Industrial HMI with Secure Boot.
Secure IoT Sensor Node
The PIC32CM5164LS60100-I/PF is an ideal host for battery-powered secure IoT sensor nodes. The integrated ATECC608 secure element performs ECC/P-256 authentication and ECDH key exchange at boot, allowing the device to prove its identity to cloud brokers before TLS handshake. The Cortex-M23 core at 48 MHz handles TLS 1.3 record processing while the 512 KB Flash buffers firmware updates. Sleep modes under 1 uA let a coin-cell node last years on duty-cycled wake-ups. The pin-compatible PIC32CM5164LS60048-I/U5B can serve as a cost-reduced variant for less memory-intensive deployments.
Recommended
Capacitive Touch User Interface
With the on-chip Peripheral Touch Controller (PTC), the PIC32CM5164LS60100-I/PF directly drives capacitive buttons, sliders, and proximity sensors without an external touch IC. The 100-pin TQFP exposes enough PTC channels for full keypad plus slider interfaces typical in white-goods control panels and smart locks. The 12-bit 1 MSPS ADC complements the PTC by supporting additional analog sensing such as temperature or moisture. Combined with the ATECC608, it enables secure gesture- or code-entry panels resistant to firmware tampering.
Recommended
Smart Metering Edge Node
Smart meters require cryptographic identity for grid enrollment plus ultra-low-power operation. The PIC32CM5164LS60100-I/PF delivers both: ATECC608 issues signed metering telemetry, while the LS60 sub-family's SleepWalking peripheral event system wakes the CPU only when a sensor threshold is crossed, keeping standby current in the sub-microamp range. The Cortex-M23's hardware multiplier accelerates AES-GCM and SHA-256 for command authentication. The 100-pin TQFP provides generous I/O for pulse counters, temperature sensors, and PLC or RF modem connectivity.
Recommended
Secure Wearable Medical Device
Wearable medical devices must encrypt patient telemetry to meet HIPAA and FDA cybersecurity guidance. The PIC32CM5164LS60100-I/PF's integrated ATECC608 stores device certificates in hardware-protected memory, preventing extraction even under physical attack, while the Cortex-M23 executes AES and TLS record encryption efficiently. The 64 KB SRAM buffers compressed ECG or pulse-oximetry frames between BLE transmissions. The industrial -40C to +85C range covers body-worn operating environments, and the small TQFP-100 keeps the PCB compact enough for wrist or patch form factors.
Recommended
Smart Lock and Access Control
Smart locks require authenticated firmware, secure key storage, and a touch keypad. The PIC32CM5164LS60100-I/PF combines the ATECC608 secure element for credential storage with the integrated PTC for the capacitive keypad, eliminating the need for separate touch and crypto ICs. The Cortex-M23 enforces anti-tamper logic and lock actuator control. Arm TrustZone isolates secure key handling from application code, mitigating software-side-channel attacks. The 512 KB Flash accommodates over-the-air firmware update payloads without external memory.
Recommended
Industrial HMI with Secure Boot
Industrial human-machine interfaces need deterministic touch response, secure firmware, and extended-temperature operation. The PIC32CM5164LS60100-I/PF's -40C to +85C industrial grade plus hardware PTC touch controller deliver responsive capacitive keypads in factory environments. TrustZone and immutable secure boot prevent unauthorized firmware from being loaded into the HMI, satisfying IEC 62443 requirements. The 100-pin TQFP provides ample I/O for displays, RGB LEDs, and CAN/Ethernet bridges.

Key Differentiators
- Integrated ATECC608 secure element saves BOM cost and PCB area (vs PIC32CM5164LS00100-I/PF)
- Higher memory density than lower-cost variants (vs PIC32CM2532LS60100-I/PF)
- Cortex-M23 with TrustZone + crypto acceleration (vs Generic Cortex-M0+ MCUs without TrustZone)
Design Notes
Place a 100 nF X7R decoupling capacitor as close as possible to every VDD/VDDIO pin pair, with an additional 4.7 uF bulk capacitor near the package. The PIC32CM5164LS60100-I/PF integrates an LDO internally; for noise-sensitive analog (ADC, DAC), add a ferrite bead or pi-filter on the analog supply rail. Estimated: with 100 nF + 4.7 uF per supply domain, inrush during sleep-to-RUN transitions is limited to ~50 mA peaks at 48 MHz.
Do NOT bypass the ATECC608 secure element. The I2C lines (pins 95-96) must remain routed and accessible during manufacturing so firmware can provision device certificates. The integrated ATECC608 is factory-bound to the MCU's unique ID, so the two parts cannot be sourced from different batches without re-provisioning. The LS60 variant requires 2.0 V minimum VDD; dropping below this will disable the secure element. Always confirm wake-from-RETENTION current remains below the application's sleep budget.
Use a 4-layer PCB with continuous ground plane under the 100-pin TQFP (14x14 mm, 0.5 mm pitch). Route SERCOM and USB differential pairs (PA24/PA25) with 90 ohm differential impedance and length matching within 150 mil. Place the 32.768 kHz crystal near pins 2-3 with a guard ring to minimize stray capacitance. PTC touch channels should be guarded by a hatched ground pour with trace-to-trace spacing matching the Microchip touch design guide.
