PIC32CM5164LS60064-I/PT 概要
A 32-bit microcontroller (MCU) is a programmable System-on-Chip that combines a processor core, non-volatile program memory (typically Flash), volatile working memory (SRAM), and a rich peripheral set on one die. Modern MCUs sit at the hierarchy MCU -> embedded controller -> semiconductor. Cortex-M23 specifically is the smallest Armv8-M core with TrustZone security extensions, positioned between Cortex-M0+ (basic) and Cortex-M4 (DSP+FPU), making it ideal for low-power secure IoT endpoints.
Key features of this part include 512 KB Flash for firmware, 64 KB SRAM for working data, TrustZone isolation, hardware crypto accelerators via ATECC608, up to 64 KB EEPROM emulation, multiple SERCOM-configurable peripherals (USART, I2C, SPI), 12-bit ADC with up to 16 channels, and integrated touch controller hardware with driven shield support for robust proximity sensing. The 64-pin TQFP offers ample I/O for human-machine interface and mixed-signal designs.
Architecturally, the device uses an ultra-low-power architecture featuring multiple sleep modes (IDLE, STANDBY, BACKUP with full RAM retention), an Event System for autonomous peripheral interaction without CPU wake-up, and a Sleepwalking Peripheral System. The integrated ATECC608 Trust Platform provides immutable secure boot, secure key storage, and cryptographic authentication.
Typical applications include secure IoT endpoints (TLS-authenticated sensors, smart locks), consumer HMI with touch (appliance panels, smart thermostats), industrial sensor hubs with secure firmware update, battery-powered wearables, and home automation bridges. The combination of low-power sleep modes and TrustZone security makes it especially compelling for always-on edge nodes that must authenticate cloud connections without draining battery reserves.
When designing with this part, choose a toolchain from MPLAB X (XC32 compiler) and configure TrustZone from project initialization. Plan the pinout around the integrated touch channels if you intend to use driven shield, and budget Flash/RAM to leave room for a secure bootloader image in the secure region.

Secure IoT Sensor Endpoints
The PIC32CM5164LS60064-I/PT is engineered for secure IoT sensor endpoints that must authenticate cloud connections and resist firmware tampering. Its integrated ATECC608 Trust Platform provides hardware-backed key storage and immutable secure boot, while TrustZone for Armv8-M isolates the crypto stack from the main application. With 512 KB Flash, the device fits full TLS clients plus an RTOS; the 64 KB SRAM retains a TLS session context during deep-sleep. Multiple low-power modes plus the Sleepwalking Peripheral System enable multi-year battery life on coin cells. Recommended companion parts: Microchip ATECC608B for additional crypto slots and a Microchip MCP9808 temperature sensor for environmental telemetry.

Consumer HMI with Touch
This MCU excels at consumer human-machine interface (HMI) panels that combine a small TFT/LCD with capacitive touch buttons, sliders, and proximity sensing. The PIC32CM5164LS60064-I/PT integrates a touch controller with driven shield support, allowing reliable operation through thick glass or plastic overlays. The 64-pin TQFP offers ample GPIO for LCD parallel interfaces plus LEDs and key scanning. SERCOM peripherals handle I2C/SPI sensors behind the panel. Low-power IDLE and STANDBY modes let the device sleep while still waking on a touch event.

設計ノート
Place a 1 uF X7R ceramic decoupling capacitor within 3 mm of each VDD pin pair on the PIC32CM5164LS60064-I/PT, plus a bulk 10 uF tantalum or aluminum-polymer capacitor near the package. The device supports BACKUP mode with full 64 KB SRAM retention, drawing typically <2 uA - critical for always-on IoT sensors that must preserve TLS session state across sleep cycles. Estimated: at VDD = 3.3V with a 1 mA active current, average consumption of 5 uA (0.1% active duty cycle) yields a 2200 mAh coin cell life of roughly 10 years. Decouple the analog AVSS/AVDD pins separately when using the 12-bit ADC.
The 64-pin TQFP (PT) package provides a thermal resistance theta_JA around 50 C/W on a 2-layer JEDEC test board with minimal copper. The Cortex-M23 at typical 48-64 MHz operation dissipates under 0.3 W, well within package capability. Estimated: at 0.3 W dissipation and theta_JA = 50 C/W, junction temperature rises approximately 15 C above ambient at 25 C - a safe 40 C margin under the 125 C maximum. For continuous worst-case operation at 85 C ambient, verify thermal envelope with the actual PCB copper area, especially if the device is co-located with hot power components.
Route the SWDIO (pin 30) and SWDCLK (pin 31) signals to a 2x5 0.05C Tag-Connect or Cortex Debug connector with at most 30 mm trace length, keeping them away from switching signals. The RESET pin (pin 63) requires a 10 kohm pull-up to VDD plus a 100 nF capacitor to ground for noise immunity. For touch sensing channels, ensure 2 mm trace clearance and avoid running noisy signals (high-speed SERCOM, switching power) within 5 mm of touch traces, or use the driven shield function to maintain touch sensitivity in noisy environments. The exposed pad (if present in this TQFP variant - verify) should be soldered to a thermal copper pour for improved heat dissipation.
A frequent mistake is failing to configure TrustZone at project initialization in MPLAB X - the device will boot in non-secure mode by default, leaving the ATECC608 Trust Platform inaccessible to application code. Enable the TrustZone project option in XC32 compiler settings before building the secure bootloader. Another common pitfall: assigning touch channels to PB12-PB15 (pins 51-54) without enabling driven shield - these pins share analog resources and may show reduced sensitivity without proper configuration. Always verify the device silkscreen marking against the datasheet to distinguish LS60064 (with ATECC608) from LS00064 (without ATECC608) at incoming QC, as the same TQFP-64 footprint is used for both variants.
For SERCOM peripherals running at high SPI speeds (above 12 MHz), place 22-33 ohm series damping resistors near the source pins to dampen ringing on long PCB traces. The 12-bit ADC achieves its best noise performance (better than 1 LSB RMS) when the analog input traces are guarded by GND pours and the analog AVDD is filtered with a ferrite bead plus 100 nF capacitor. Estimated: with a 1 kHz ADC sample rate, input frequency below 500 Hz, and the recommended input filter, the effective number of bits (ENOB) should remain at 11+ bits, suitable for sensor readout applications such as temperature, pressure, and gas sensing.
