PIC32CM5164LS00100-I/PF 概述
A microcontroller (MCU) is a single-chip computer that combines a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and configurable peripherals (GPIO, timers, ADC, communication interfaces) on one die. Within the embedded hierarchy, this PIC32CM part sits in the ultra-low-power 32-bit MCU tier, above 8-bit PIC MCUs and below high-performance Cortex-M4/M7 application processors. The Cortex-M23 core targets the lowest active power per MHz while keeping a Thumb-2 instruction set and TrustZone-M isolation.
Key features include 80 general-purpose I/O, a 1.62 V to 3.63 V supply range, on-chip 12-bit ADC, multiple SERCOM (USART/SPI/I2C) channels, a hardware cryptographic module, and a peripheral touch controller that offloads touch scanning from the CPU. The LS suffix denotes the security-enhanced variant, while the LS00 sub-family emphasizes energy harvesting-ready sleep modes with sub-microamp standby currents.
Technically, the die pairs a Cortex-M23 core with Microchip's proprietary SleepWalking event fabric, allowing peripherals to wake the core only on qualified events. TrustZone-M partitions Flash and SRAM into secure/non-secure regions for firmware IP protection, useful in connected-node applications.
Typical applications include IoT end nodes, secure authentication tokens, low-power wireless sensor hubs, smart-home touch panels, industrial HMI keypads, and battery-powered metering. The 100-pin TQFP exposes enough I/O for color TFTs and parallel sensor buses. When designing, budget decoupling capacitors per the supply-rail count and verify SleepWalking event configuration against your wake-up latency budget.

典型应用
PIC32CM5164LS00100-I/PF 适用于 6 应用s: Battery-Powered IoT End Node, Secure Authentication Token, Industrial HMI Touch Keypad, Smart Home Touch Panel, Wireless Sensor Hub, Battery-Powered Metering.
Battery-Powered IoT End Node
The PIC32CM5164LS00100-I/PF's Cortex-M23 core at 48 MHz delivers ample compute for LoRaWAN or BLE stack processing while SleepWalking peripherals keep standby current in the sub-microamp range. TrustZone-M isolates the secure key store from the application firmware, enabling safe OTA updates. A typical coin-cell node draws <1 uA average when SleepWalking qualifies sensor wake-ups at 1 Hz intervals.
推荐
Secure Authentication Token
The LS variant's hardware crypto accelerator and TrustZone-M make PIC32CM5164LS00100-I/PF ideal for FIDO2, secure boot, or device authentication tokens. 512 KB Flash accommodates TLS stacks and certificate storage, while 8 KB EEPROM holds device identity. The 100-pin TQFP exposes USB-capable pins for direct host interfacing in two-factor key designs.
推荐
Industrial HMI Touch Keypad
The Peripheral Touch Controller (PTC) offloads capacitive touch scanning from the Cortex-M23 CPU, allowing the panel to handle 50+ touch keys at low power. 80 GPIO drive TFT displays, LEDs, and segment indicators directly. The 1.62-3.63 V range supports industrial 24 V bus-powered designs through a front-end LDO.
推荐
Smart Home Touch Panel
The PIC32CM5164LS00100-I/PF drives 3.5-inch TFT touch panels with sub-100 mW active power. SleepWalking enables always-on voice or proximity sensing without draining the wall-supply budget. TrustZone-M secures Z-Wave or Matter commissioning credentials, critical for connected home privacy compliance.
推荐
Wireless Sensor Hub
The PIC32CM5164LS00100-I/PF aggregates data from multiple sensor SERCOM (SPI/I2C) channels while running edge analytics. 512 KB Flash stores time-series buffers, and 64 KB SRAM supports sliding-window DSP. SleepWalking events from any sensor wake the CPU only when anomaly thresholds trip, maximizing battery life in field deployments.
推荐
Battery-Powered Metering
The PIC32CM5164LS00100-I/PF's wide 1.62-3.63 V supply allows direct connection to 3.6 V Li-SOCl2 primary cells used in metering. Cortex-M23 compute handles billing algorithms and signed firmware updates; TrustZone-M protects tamper-detection routines. The 100-pin TQFP accommodates parallel LCD segment drivers alongside the metering ADC.

设计说明
Estimated: Decoupling budget for PIC32CM5164LS00100-I/PF follows Microchip's reference design with 100 nF X7R per VDD pin and a single 4.7 uF bulk on the main rail. When running at 48 MHz, the core draws roughly 7 mA active; SleepWalking drops this below 1 uA when peripherals wake the CPU. Place bulk caps within 5 mm of the supply pins to keep the high-frequency impedance low.
Route the 100-pin TQFP fan-out using 0.2 mm trace/space with the inner rows escaping between the outer-row pads. Place the 32.768 kHz crystal within 5 mm of the XIN/XOUT pins and guard it with a ground pour to minimize load-capacitance drift. Keep SERCOM and PTC traces short and adjacent to ground to limit crosstalk into the touch sense inputs.
Do not enable TrustZone-M in production firmware without first provisioning the secure flash region and locking debug access - otherwise the security benefits are voided. Verify SleepWalking event configuration against your wake-up latency budget; misconfigured event qualifiers keep the core awake and defeat the low-power advantage. Always check that the chosen 100-pin TQFP variant matches the I/O count you require (80 GPIO available).
