PIC32CM2532LS60048-I/U5B Overview
What is a PIC32CM LS00 microcontroller? The PIC32CM LS00 is Microchip's ultra-low-power ARM Cortex-M23 MCU family that combines SleepWalking peripherals (event-driven wake-up without CPU intervention), industry-leading touch sensing hardware (PTC), and security features such as secure boot and cryptographic accelerators. Within the broader semiconductor taxonomy, PIC32CM LS00 belongs to the Cortex-M23 class of microcontrollers, which itself is a subset of ARM Cortex-M microcontrollers, then microcontrollers, then microprocessors, then integrated circuits. The LS00 sub-family is the secure-touch variant targeting human-machine interface and IoT edge applications.
Key features include 512 KB dual-bank Flash with ECC, 32 KB SRAM, hardware crypto accelerators (AES, SHA, TRNG), up to 256 KB of user-programmable secure Flash, 12-bit 1 Msps ADC, and a Peripheral Touch Controller supporting buttons, sliders, and proximity sensors. The device integrates multiple serial interfaces (SERCOM configurable as UART/SPI/I2C), I2S, USB 2.0 Full-Speed device/host, and CAN-FD. Power consumption is engineered below 30 uA/MHz active and sub-uA in deep sleep.
The architecture pairs the Cortex-M23 core (Armv8-M baseline, TrustZone for Cortex-M absent here) with Microchip's proprietary SleepWalking peripherals that wake only the minimum subsystem needed for an event, keeping average system current at the uA level. The dual-bank Flash with EEPROM emulation enables robust firmware updates and parameter storage.
Typical applications include secure IoT edge nodes, capacitive touch user interfaces (buttons, sliders, wheels), home appliances with HMI panels, secure connected sensors with firmware update requirements, low-power wireless sensor gateways, and industrial control panels. The combination of low power and integrated touch makes it well suited for battery-powered smart devices requiring both clean user input and secure cloud connectivity.
When designing with this device, pay attention to the U5B package thermal resistance and ensure the secure boot configuration bits are correctly programmed in NVM. For touch applications, follow the PCB layout guidelines in the device datasheet for sensor routing and ground flooding.

Typical Applications
PIC32CM2532LS60048-I/U5B is suitable for 6 applications: Secure IoT Edge Node with Touch HMI, Home Appliance User Interface Panel, Secure Connected Sensor with Firmware Update, Industrial Control Panel with Touch Buttons, Battery-Powered Smart Lock / Access Control, Low-Power Wireless Sensor Gateway.
Secure IoT Edge Node with Touch HMI
The PIC32CM2532LS60048-I/U5B fits this application because its 48 MHz Cortex-M23 core delivers enough DMIPS for TLS handshake and JSON parsing while hardware AES/SHA accelerators offload cryptographic operations at sub-mJ per transaction. The Peripheral Touch Controller supports buttons, sliders, and proximity sensors in deep sleep at sub-uA current, eliminating the need for a separate touch IC. Placed as the single SoC on the board, the device negotiates Wi-Fi/BLE co-processor commands over UART, performs secure boot, and presents a touch HMI on the same silicon. Concrete benefit: average sleep current stays below 3 uA with a 10 Hz touch scan rate, enabling coin-cell operation for years in connected sensor products.
Recommended
Home Appliance User Interface Panel
The PIC32CM2532LS60048-I/U5B is well suited to home appliance UI panels because its integrated touch sensing and segment-LCD capable peripherals replace multiple discrete ICs (touch controller + LCD driver + main MCU). With 512 KB Flash it can host a graphical UI framework plus power-management firmware. The Cortex-M23 core handles motor-control supervisory loops and BLE/Wi-Fi provisioning through a co-processor. A typical implementation pairs the device with an SPI segment LCD and a power-line or battery supply; the LS00 security block protects the brand identity against firmware cloning, a common concern in white-goods markets.
Recommended
Secure Connected Sensor with Firmware Update
The PIC32CM2532LS60048-I/U5B meets OTA firmware update requirements because its dual-bank Flash architecture allows a new image to be written to the inactive bank while the active bank runs production firmware, then swapped in a single reboot with no downtime. Hardware AES-256 and SHA-256 offload signature verification at low energy, enabling secure boot in <500 ms on coin-cell. The 32 KB SRAM is sufficient for TLS record buffers plus small JSON payloads, and the Cortex-M23 at 48 MHz reaches ample throughput for periodic sensor reads plus secure transmission.
Recommended
Industrial Control Panel with Touch Buttons
For industrial control panels, the PIC32CM2532LS60048-I/U5B integrates capacitive touch (replacing mechanical switches in industrial), CAN-FD (CAN-FD for in-plant communication with industrial machinery), and hardware crypto (industrial 3 for factory authentication). The industrial temperature range -40C to +85C allows deployment in factories and panel enclosures. A 1Msps 12-bit ADC reads analog signals from the same device, while SERCOM channels interface to RS-485 transceivers via UART, reducing total BOM.
Recommended
Battery-Powered Smart Lock / Access Control
The PIC32CM2532LS60048-I/U5B is well suited to battery-powered smart locks because the security accelerators (AES, SHA, TRNG) execute TLS handshakes and credential checks at low energy, the Cortex-M23 runs the motor control algorithm for the deadbolt, and SleepWalking peripherals wake only the touch sensor for PIN entry. Typical implementation: 4x AAA cells, BLE link to phone, touch keypad on the door exterior. Concrete benefit: average current under 5 uA in standby supports 1+ year battery life; secure boot prevents credential-replay attacks that compromise mechanical locks.
Recommended
Low-Power Wireless Sensor Gateway
The PIC32CM2532LS60048-I/U5B acts as a wireless sensor gateway because the Cortex-M23 core aggregates data from sub-GHz or BLE end nodes, and the USB 2.0 Full-Speed interface provides a convenient wired backhaul. With 512 KB Flash it can host the radio stack plus aggregator logic, and the security IP authenticates each incoming sensor message before forwarding. Typical power budget: active 30 uA/MHz, deep sleep sub-uA, average under 100 uA in a 1-second wake cycle, making it compatible with solar or coin-cell power in remote sensor installations.

Key Differentiators
- Largest Flash in PIC32CM LS00 family (vs PIC32CM2532LS00048-I/U5B)
- Integrated hardware crypto vs. non-secure LE00 (vs PIC32CM2532LE00048-I/U5B)
- Cortex-M23 vs M0+ for higher DMIPS at same frequency (vs PIC32CM2532JH00048)
Design Notes
Connect the exposed thermal pad (pin 48) of the U5B package directly to a solid GND copper pour on the top layer, stitched with at least 8 thermal vias to an inner GND plane. The 48-VQFN dissipates heat through this pad; without proper thermal connection the junction temperature will rise above the -40C to +85C industrial range under sustained 48 MHz operation. Per Microchip PCB layout guidelines, keep the GND pour unbroken beneath the device and use 0.3 mm drill / 0.5 mm pitch thermal vias for optimal heat transfer.
Place a 100 nF X7R decoupling capacitor as close as possible to each VDD/VDDIO pair, plus a 4.7 uF bulk capacitor within 5 mm. The PIC32CM LS00 device uses SERCOM pins multiplexed with analog, so noise on VDDIO directly couples into ADC readings. According to the PIC32CM-MC00 family datasheet DS60001638, the device supports a wide VDD range; confirm exact min/max in the electrical characteristics table before designing the power tree, and add a ferrite bead on analog supply if high ADC precision is required.
When migrating from PIC32CM2532LS00048 (less Flash) to PIC32CM2532LS60048 (this part), verify that your linker script reserves the upper Flash bank correctly. The LS60048 has 512 KB dual-bank; firmware update routines that worked on LS00048 may need NVM driver updates for the additional bank. Also, the security configuration bits in NVM must be programmed before first secure boot - leaving them at default state allows unsigned code execution and defeats the security IP. Refer to Microchip application note TB3285 for secure boot configuration sequence.
Compliance Information
RoHS compliant per Microchip product page. Industrial -40C to +85C temperature range (not AEC-Q100 automotive grade - choose PIC32CM JH series for automotive).
