PIC32CM5164LS60048-I/U5B Overview
A microcontroller (MCU) is an integrated circuit that combines a CPU core, memory (Flash, SRAM), and programmable peripherals on a single die. Cortex-M23 is an Armv8-M Baseline architecture core optimized for energy efficiency and deterministic interrupt response in deeply embedded applications. Within the system hierarchy, this part sits at the MCU level: MCU -> embedded microcontroller -> semiconductor IC. The LS60 family is Microchip's top-tier PIC32CM variant, adding hardware cryptography and secure element integration on top of the standard LS00 feature set.
Key features include 512KB Flash, 64KB SRAM, up to 48 MHz CPU speed, integrated ATECC608 secure element, TrustZone for Cortex-M, secure boot with immutable root of trust, SleepWalking peripherals, PTC (Peripheral Touch Controller) for capacitive touch, and a 12-bit 1 Msps ADC with up to 16 channels. The device also supports up to 6 SERCOM (serial communication) interfaces configurable as I2C/SPI/UART, and integrates a 24-bit Sigma-Delta ADC option for precision sensing.
Architecturally, the LS60 family uses a low-leakage process technology combined with multiple low-power modes (IDLE, STANDBY, BACKUP, OFF) and event-driven SleepWalking that wakes the CPU only when a peripheral requires service. This enables years of battery life on coin-cell powered IoT endpoints. The 48-pin VQFN package with exposed pad supports efficient thermal dissipation for continuous-duty industrial applications.
Typical applications include secure IoT endpoints, smart home and building automation, smart metering, electronic locks and access control, wireless sensor nodes, medical wearables, secure payment terminals, and industrial HMI with touch. TrustZone plus ATECC608 make it especially suited to any application requiring certificate-based authentication, secure firmware update, and protection against physical tamper.
Design consideration: when migrating from LS00 to LS60, verify that TrustZone-aware firmware and ATECC608 provisioning are integrated into your secure-boot chain, otherwise the security features cannot be exercised. Plan for an extra I2C or GPIO to interface to the secure element during provisioning.

Typical Applications
PIC32CM5164LS60048-I/U5B is suitable for 6 applications: Secure IoT Edge Nodes, Smart Home and Building Automation, Electronic Locks and Access Control, Smart Metering and Energy Monitoring, Medical Wearables and Patient Monitoring, Industrial HMI with Touch.
Secure IoT Edge Nodes
The PIC32CM5164LS60048-I/U5B is built for secure IoT endpoints because of its integrated ATECC608 secure element, Arm TrustZone, and immutable secure boot. The 48 MHz Cortex-M23 core plus 512 KB Flash is sufficient for TLS 1.3 handshake code, mbedTLS crypto, and an MQTT-SN or CoAP stack. SleepWalking peripherals let the device stay in BACKUP at sub-microamp current while a sensor or wakeup timer monitors the environment, then resume to full operation to push data over BLE or Wi-Fi. Compared with discrete MCU + external secure element designs, the integrated approach reduces BOM by one IC and removes an I2C bus from the security-critical path, hardening the device against bus-probing attacks.
Recommended
Smart Home and Building Automation
Smart-home hubs and building-automation controllers benefit from the PIC32CM5164LS60048-I/U5B's mix of Cortex-M23 compute, multiple SERCOM channels, and capacitive touch. The PTC enables touch buttons and sliders on wall panels without an external touch IC, while six SERCOMs can drive RS-485, I2C sensors, SPI displays, and dual UART bridges simultaneously. TrustZone plus ATECC608 make it suitable for Matter-over-Thread commissioning flows where device-attestation certificates are mandatory. Backup-mode retention lets the controller keep time and configuration across power outages, so commissioning is preserved.
Recommended
Electronic Locks and Access Control
Electronic locks need both secure credential storage and long battery life, two requirements the PIC32CM5164LS60048-I/U5B addresses natively. The on-die ATECC608 stores private keys in hardware and signs challenges without exposing them over any bus, supporting FIDO2, OATH, and custom ECC authentication flows. The 2.0 V minimum supply lets the lock run from two AA cells in series until late in their discharge curve. Cortex-M23 at 48 MHz handles keypad or NFC-driven unlock sequences in real time, while BACKUP mode with RTC keeps the device alive for months on a single battery set.
Recommended
Smart Metering and Energy Monitoring
Smart electricity, water, or gas meters are a strong fit for the PIC32CM5164LS60048-I/U5B thanks to its 12-bit 1 Msps ADC, SleepWalking peripherals, and tamper-resistant secure element. The ADC can sample current and voltage at high enough rates for class-0.5 metering accuracy, while SleepWalking lets the device sleep between measurement intervals, drawing microamp-level current on average. The LS60 variant's secure boot prevents firmware tampering - mandatory for revenue-grade metering - and ATECC608 accelerates DLMS/COSEM or ANSI C12 security handshakes.
Recommended
Medical Wearables and Patient Monitoring
Battery-powered medical wearables benefit from the PIC32CM5164LS60048-I/U5B's low-power BACKUP and STANDBY modes plus SleepWalking peripherals, which let the device sample a heart-rate or SpO2 sensor, run DSP, transmit over BLE, and return to sleep within tens of milliseconds. The Cortex-M23 at 48 MHz is fast enough to host filtering and FFT code for heart-rate variability, while the integrated ATECC608 supports secure pairing required for HIPAA-conscious Bluetooth medical profiles. The 48-pin VQFN exposed pad gives good thermal dissipation for continuous skin-contact operation.
Recommended
Industrial HMI with Touch
Industrial human-machine interfaces such as appliance control panels and HVAC thermostats benefit from the PIC32CM5164LS60048-I/U5B's PTC (Peripheral Touch Controller), which supports buttons, sliders, and proximity wake-up through a hardware-driven scan engine. Combined with the 12-bit ADC for temperature and humidity sensing plus 6 SERCOM channels for display, UART, and SPI sensor I/O, the LS60 family enables a single-chip industrial HMI. TrustZone is valuable when the panel also implements secure over-the-air update or technician authentication.

Key Differentiators
- Integrated ATECC608 secure element eliminates external security IC (vs PIC32CM5164LS00048-I/U5B)
- Highest-density PIC32CM Flash option at 48-pin VQFN (vs PIC32CM1216MC00048T-I/Y8X)
- TrustZone hardware isolation for firmware security (vs PIC32CM5164LE00048-I/U5B)
Design Notes
Decouple VDD with a 1uF X7R ceramic close to each power pin and a 10uF bulk capacitor on the exposed pad (EP) ground. The EP must be soldered to a continuous ground plane for thermal and electrical reasons; floating EP can cause latch-up and erratic ADC readings. For battery applications, source VDD from an LDO with sub-1uA quiescent current (e.g., MCP1700) so the MCU's BACKUP mode is not masked by LDO Iq.
Estimated: at 48 MHz active with all SERCOMs and ADC running, typical Vcore current is about 5 mA at 3.3 V, so power dissipation is ~16.5 mW. In BACKUP mode with RTC running the IC draws under 2 uA, so thermal management is only a concern in continuous-active industrial HMI. The 48-pin VQFN EP provides the primary heat-spreading path; do not rely on top-side cooling.
If migrating from LS00 to LS60, you must re-provision the ATECC608 with new keys and certificates - a blank ATECC608 will lock out secure boot. Also, TrustZone enables a secure / non-secure memory split; existing firmware that treats all memory as non-secure will fault at first secure-region call. Use MPLAB Harmony 3 config tools to set the SAU (Security Attribution Unit) regions correctly before first power-up.
Keep SERCOM signal traces under 25 mm if possible; for I2C, use 4.7 kohm pull-ups and place the I2C pull-up resistors near the MCU. The ADC inputs are sensitive - keep analog traces short, route them away from SERCOM switching lines, and place the AGND pin return directly to the EP ground pour. Add a guard ring around the ADC pins if measuring sub-millivolt signals.
Compliance Information
