PIC32CM2532LS60064-I/PT - 32-bit Cortex-M23 MCU, 256KB Flash, 64-TQFP | Microchip
MPN: PIC32CM2532LS60064-I/PT ✓ ActivePIC32CM2532LS60064-I/PT Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of peripherals including timers, ADC/DAC, communication interfaces (UART/SPI/I2C), and GPIO. Cortex-MMC PIC32CM LS00 devices are ultra-low-power MCUs designed around the ARM Cortex-M23 core, the smallest and most energy-efficient Cortex-M processor with TrustZone-M optional hardware isolation. They sit in the hierarchy: Cortex-M23 -> ARM Cortex-M -> 32-bit RISC MCU -> embedded microcontroller -> integrated circuit.
Key specifications: 256 KB Flash (256K x 16), 64 KB SRAM, 48 MHz maximum CPU clock, 64-pin TQFP (PT) package, 1.71V to 3.63V operating voltage, integrated 12-bit ADC, op-amps, DAC, and capture-compare PWMs. The device features SleepWalking peripherals that wake only the necessary sub-system while keeping the CPU asleep, plus a hardware crypto accelerator and secure boot. The 64-pin TQFP package provides 51+ GPIO pins and a 10x10 mm body suited for hand-solderable prototypes and low-density production boards.
Typical applications: secure IoT sensor nodes, smart-home HMI touch panels, low-power wireless sensor hubs, secure BLE/wifi nodes, battery-powered data loggers, and industrial touch controls. The 256KB Flash accommodates Over-the-Air (OTA) update firmware plus dual-image secure boot, while 64KB SRAM allows modest protocol stacks (Zigbee, BLE, Matter) without external memory.
Design tip: route the decoupling capacitors (100 nF + 1 uF) within 2 mm of each VDD/AVDD pin pair and use a continuous ground pour under the TQFP thermal pad to keep the ADC noise floor low. Use the integrated op-amps for sensor signal conditioning before the ADC to reduce BOM cost.

Typical Applications
PIC32CM2532LS60064-I/PT is suitable for 6 applications: Secure Battery-Powered IoT Sensor Node, Smart-Home HMI Touch Panel, Industrial Touch Control / Appliance HMI, Wearable Health Monitor, Low-Power Wireless Sensor Hub, Secure Access Control Reader.
Secure Battery-Powered IoT Sensor Node
The PIC32CM2532LS60064-I/PT is ideal for secure battery-powered IoT sensor nodes that must run for years on a coin-cell or 2x AA battery while remaining Internet-connected via BLE/Zigbee/wifi. Its 1.71 V to 3.63 V operating range directly supports a depleted coin cell, and the SleepWalking peripherals wake only the necessary sub-system while keeping the CPU asleep at sub-uA current. The 256 KB Flash accommodates OTA update firmware plus dual-image secure boot using TrustZone-M hardware isolation.
Recommended
Smart-Home HMI Touch Panel
The PIC32CM2532LS60064-I/PT integrates enhanced touch hardware (PTC peripheral) that supports button, slider, and wheel touch interfaces without external touch ICs, reducing BOM cost in smart-home HMI panels. The 12-bit ADC and integrated op-amps provide sensor signal conditioning for proximity and ambient-light sensors, while the 48 MHz Cortex-M23 core supports 60 Hz UI refresh rates. The 64-pin TQFP exposes 51+ GPIO for driving RGB LEDs, displays, and relay outputs.
Recommended
Industrial Touch Control / Appliance HMI
The PIC32CM2532LS60064-I/PT supports industrial touch-control panels and white-goods appliance HMIs where the -40 C to +85 C industrial temperature range and 1.71 V to 3.63 V wide supply tolerance handle motor-noise-induced voltage fluctuations. The enhanced PTC peripheral supports reliable touch buttons through glass and plastic overlays, while the integrated op-amps condition sensor inputs (NTC temperature, capacitive level). The 64-pin TQFP is hand-solderable for low-volume prototyping.
Recommended
Wearable Health Monitor
The PIC32CM2532LS60064-I/PT fits wearable health monitors because its 1.71 V to 3.63 V supply supports direct Li-ion battery connection with no boost converter, while the integrated 12-bit ADC and op-amps handle PPG, ECG, and bio-impedance sensor front-ends. The SleepWalking peripherals let the MCU wake only when a physiological event is detected, extending battery life to weeks. The small 64-pin TQFP (10x10 mm) fits inside small wrist-form-factor enclosures.
Recommended
Low-Power Wireless Sensor Hub
The PIC32CM2532LS60064-I/PT works as a low-power wireless sensor hub coordinating BLE/Zigbee/LoRa modules in mesh networks. The 256 KB Flash supports a Zigbee or Matter protocol stack with room for application firmware, while the 64 KB SRAM holds routing tables and message buffers. The Cortex-M23 at 48 MHz handles crypto-accelerated TLS 1.3 handshakes without overloading the CPU, and the SleepWalking peripherals keep the radio off between transmissions.
Recommended
Secure Access Control Reader
The PIC32CM2532LS60064-I/PT is well-suited for secure access-control readers using TrustZone-M hardware isolation to keep credential storage and crypto operations in a separate secure world from the application world. The integrated crypto accelerator handles AES/SHA/RSA operations on credential verification within milliseconds, while the 256 KB Flash holds credential libraries and reader firmware. The 64-pin TQFP drives a keypad, RFID antenna, and LED indicators directly.

Key Differentiators
- TrustZone-M hardware isolation for secure firmware partitioning (vs PIC32CM2532LS00064-I/PT)
- Lower price per unit at cost of Flash density (vs PIC32CM2532LS00064-I/PT)
- Same Cortex-M23 core with SleepWalking peripherals (vs PIC24HJ64GP504-I/PT (16-bit legacy MCU))
Design Notes
Place 100 nF ceramic decoupling capacitors within 2 mm of every VDDIO pin pair and add a single 1 uF bulk capacitor on the main VDD rail. The PIC32CM2532LS60064-I/PT integrates multiple VDDIO domains; route each pair independently to a continuous ground pour to minimize switching-induced ADC noise floor. Estimated: at 48 MHz active and 3.3 V supply, the core draws approximately 3 mA per MHz (~144 mW), while Sleep mode current drops below 10 uA per Microchip family datasheet typical values.
Use a 4-layer PCB with a continuous ground plane on layer 2 directly beneath the 64-pin TQFP to provide a low-impedance return path for high-speed signals. The TQFP-64 10x10 mm body has 0.5 mm pitch leads; route signals on inner layers with micro-vias. Keep the analog inputs (PA02-PA07) physically separated from digital switching traces to avoid ADC crosstalk.
Do not skip the external 32.768 kHz crystal load capacitors; the PIC32CM2532LS60064-I/PT requires accurate load capacitance to maintain RTC accuracy within +/- 20 ppm. When using TrustZone-M, partition the secure and non-secure linker regions explicitly during firmware build; leaving them merged disables TrustZone benefits silently. Finally, verify the bootloader pins match the application firmware's expected boot source or the device may appear bricked after first programming.
The 64-pin TQFP leads are 0.5 mm pitch and require careful trace routing to maintain 50 ohm impedance. For clock traces (XIN, XOUT), keep trace length under 10 mm and surround with ground pour. Estimated: at 48 MHz, signal rise time is approximately 3 ns; trace stubs longer than 5 mm may cause reflections that disrupt Cortex-M23 core operation.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified; for automotive applications choose an automotive-qualified variant with -40C to +125C temperature range.
