PIC32CM5164LS60064T-I/PT 概述
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals. The Cortex-M23 is an Armv8-M Baseline core optimized for energy efficiency with TrustZone security extensions for isolated firmware execution. The PIC32CM LS60 family sits in Microchip's ultra-low-power MCU portfolio, bridging the gap between simple Cortex-M0+ parts and higher-tier Cortex-M4 devices by combining strong security, low power, and smart analog integration in a single die.
Key features include a 48 MHz maximum CPU clock, 512 KB Flash, 64 KB SRAM, a 12-bit ADC with up to 16 channels, multiple SERCOM interfaces configurable as UART/SPI/I2C, and PTC (Peripheral Touch Controller) for capacitive touch sensing. The integrated ATECC608 secure element provides hardware-based ECDSA, ECDH, AES-128, SHA-256, and secure key storage, while the TrustZone-aware secure boot enforces immutable root-of-trust at reset.
The architecture leverages a Cortex-M23 core with single-cycle multiply and a 2-stage pipeline, balancing deterministic interrupt response with low dynamic current. Multiple low-power modes (Idle, Standby, Backup, and Off) extend battery life to single-digit microampere levels in sleep. Hardware crypto accelerators offload ECC and AES operations from the CPU, enabling faster TLS handshakes at lower energy budgets.
Typical applications include IoT end nodes, secure sensor hubs, smart-home devices with touch interfaces, industrial sensor modules, secure access control, and medical wearables. The integrated touch controller and crypto accelerators remove the need for external secure ICs, reducing BOM cost and PCB footprint.
Design considerations for this MCU include ensuring the 64-pin TQFP layout supports the required decoupling network (typically 100 nF per VDD pin and 4.7 µF bulk) and that firmware configures TrustZone boundaries correctly to prevent accidental asset lockout. Migration between LS60 family members with different Flash/RAM densities is straightforward because all variants share the same pinout.

典型应用
PIC32CM5164LS60064T-I/PT 适用于 6 应用s: Secure IoT End Nodes, Capacitive Touch HMI, Industrial Sensor Modules, Secure Access Control, Battery-Powered Medical Wearables, Smart Home Edge Devices.
Secure IoT End Nodes
The PIC32CM5164LS60064T-I/PT is ideal for secure IoT end nodes that must authenticate to cloud services while running on battery or harvested energy. Its integrated ATECC608 secure element performs hardware ECDSA and ECDH key exchanges, allowing TLS 1.3 handshakes in milliseconds without an external crypto IC. With Cortex-M23 TrustZone, application firmware runs isolated from secure assets, while the 64 KB SRAM and 512 KB Flash accommodate a full TLS stack plus an RTOS such as FreeRTOS. Active current stays below 50 uA/MHz, and deep-sleep modes drop to single-digit microamperes, enabling multi-year battery life for sensor nodes reporting every few minutes.
推荐
Capacitive Touch HMI
The PIC32CM5164LS60064T-I/PT excels in capacitive touch human-machine interface (HMI) designs thanks to its integrated Peripheral Touch Controller (PTC). The PTC supports self-capacitance and mutual-capacitance scanning, enabling robust touch keys, sliders, and proximity sensors even through thick glass overlays. Hardware-driven touch scanning offloads the CPU, freeing it to manage communications and UI logic. Combined with the 12-bit ADC for analog sensors and SERCOM-configurable UART/SPI/I2C for display drivers, this part delivers a single-chip HMI solution for appliances, smart-home panels, and industrial control interfaces requiring waterproof or glove-friendly touch.
推荐
Industrial Sensor Modules
The PIC32CM5164LS60064T-I/PT fits industrial sensor modules needing deterministic real-time performance, secure field firmware, and reliable operation from -40C to +85C. The Cortex-M23 core delivers predictable interrupt latency for time-critical measurement loops, while TrustZone isolates calibration data and signed firmware from user-accessible application logic. The 12-bit ADC with up to 16 channels supports multi-sensor inputs (temperature, pressure, flow), and SERCOM interfaces handle RS-485, CAN, or isolated SPI links to PLCs or gateways. Wide 1.62V-3.6V supply range tolerates industrial 24V bus rails with regulator headroom.
推荐
Secure Access Control
The PIC32CM5164LS60064T-I/PT is well matched to secure access control systems such as smart locks, biometric readers, and asset trackers where cryptographic key protection is mandatory. The on-die ATECC608 securely stores private keys with hardware-level tamper resistance, and immutable secure boot prevents replacement with rogue firmware. TrustZone partitions cryptographic operations from the main application, allowing the lock actuator logic to run untrusted while keys remain locked away. The 64 KB SRAM buffers image data or proximity-radio frames, and the 64-pin TQFP package integrates easily into compact reader enclosures.
推荐
Battery-Powered Medical Wearables
The PIC32CM5164LS60064T-I/PT suits battery-powered medical wearables such as continuous glucose monitors, pulse oximeters, and smart patches. Its ultra-low-power picoPower architecture achieves sub-microampere sleep currents that extend coin-cell battery life beyond a year. The integrated secure element protects PHI data with hardware AES, and TrustZone isolates diagnostic algorithms from user-facing code. The Cortex-M23 core handles sensor sampling and on-device filtering at low active current, while the PTC enables touch-capable user inputs without mechanical buttons - critical for waterproof wearable enclosures.
推荐
Smart Home Edge Devices
The PIC32CM5164LS60064T-I/PT fits smart-home edge devices such as connected thermostats, leak detectors, and security panels where local intelligence and secure cloud connectivity coexist. The Cortex-M23 core runs edge analytics on motion, temperature, or humidity data while keeping private sensor data local via TrustZone isolation. The ATECC608 handles mutual authentication with cloud brokers such as AWS IoT or Azure IoT Hub, eliminating the need for a discrete crypto IC. The Peripheral Touch Controller adds premium glass-front-panel interfaces, and multiple SERCOM ports connect to Wi-Fi or Thread co-processors for mesh networking.

设计说明
Place a 100 nF decoupling capacitor on every VDD pin and a single 4.7 uF bulk capacitor near the package. The 64-pin TQFP distributes multiple VDD/VDDIO pins; missing decoupling on any of them can trigger brownouts during low-sleep wake-up events. For battery applications, route the MCU's wake-up pin to a low-leakage RTC source and gate unused SERCOM clock trees in the CLKCTRL registers to minimize active current.
TrustZone misconfiguration is the most common firmware lockout scenario on the PIC32CM LS60 family. Always reserve the immutable bootloader region before programming secure assets, and ensure the NVMCTRL security bit is set only after validating the application image signature. A locked device cannot be debugged via standard SWD - you must use the Microchip Programming and Debugging Interface (PDI) recovery procedure.
The 64-pin TQFP has a 0.5 mm pitch and requires careful land pattern design. Use Microchip's recommended land pattern with solder mask defined (SMD) pads to avoid tombstoning during reflow. Keep high-speed SERCOM traces length-matched within 5 mm if using SPI at >10 MHz, and provide a continuous ground return path beneath trace runs to reduce EMI on the analog ADC inputs.
At maximum active load (Cortex-M23 @ 48 MHz, all peripherals enabled), the MCU dissipates roughly 30-40 mW. The TQFP-64 package theta_JA is approximately 50 C/W, yielding a junction rise of only a few degrees above ambient. However, in sealed enclosures, derate by ensuring the enclosure provides at least 10 C/W thermal coupling to ambient or use the exposed-pad variants (VQFN) for better dissipation.
