PIC32CM5164LE00100-I/PF Обзор

The Microchip Technology PIC32CM5164LE00100-I/PF is an ultra-low-power 32-bit ARM Cortex-M23 microcontroller with 512 KB Flash and 64 KB SRAM, housed in a 100-pin TQFP (14x14 mm) package. It operates from 1.62V to 3.63V at up to 48 MHz core clock, delivering 1.03 DMIPS/MHz (Dhrystone) and 2.64 CoreMark/MHz while drawing only tens of microamperes in active mode. The device is part of the PIC32CM LE00 family, which integrates SleepWalking peripherals, hardware touch (PTC), and smart analog for sensor and HMI applications.

A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory, data memory, and a rich set of programmable peripherals on a single die. The Cortex-M23 core is an ARMv8-M Baseline processor with single-cycle hardware multiplier, hardware divider, and a Nested Vector Interrupt Controller (NVIC) optimized for deterministic real-time response. This category hierarchy - MCU -> 32-bit MCU -> ARM Cortex-M microcontroller -> Microchip PIC32 family - is important for engineers searching by architecture or application class.

Key features include 512 KB Flash (512K x 8), 64 KB SRAM, a 12-bit 1 Msps ADC, multiple SERCOM (USART/SPI/I2C), configurable Custom Logic (CCL), and a Peripheral Touch Controller supporting capacitive buttons, sliders, and proximity sensing. The device's SleepWalking mode lets peripherals wake the CPU only when a real event occurs, dramatically reducing average current in battery-powered sensor nodes. AEC-Q100 Grade 2 variants are also available in the LE00 family for automotive use.

Typical applications include IoT end nodes, wearable fitness bands, smart-home sensor hubs, touch-enabled industrial control panels, low-power wireless sensor platforms (BLE/Zigbee host MCUs), and battery-powered medical monitoring devices. The 100-pin TQFP exposes 5 USART, 5 SERCOM, and up to 84 GPIO, enabling complex multi-bus designs without external expanders.

Designers should plan decoupling carefully: place 100 nF + 4.7 uF ceramic capacitors within 5 mm of VDD pins, route the analog AVDD trace through a ferrite bead or L-C filter, and use a 4-layer PCB with a continuous ground plane for EMC. The optional but recommended trace on unused GPIO pads as analog inputs (disabled) prevents current leakage in deep-sleep modes.

The PIC32CM5164LE00100-I/PF operates from 1.62 V to 3.63 V across -40 C to +85 C. According to the Microchip 60001615E family datasheet, the LE00 sub-family's wide supply range enables direct connection to single-cell Li-ion or LiFePO4 batteries (3.0-3.6 V nominal) as well as 1.8 V regulated rails without level shifters, simplifying battery-powered IoT designs.

Is the PIC32CM5164LE00100-I/PF suitable for low-power IoT designs?

Yes, the PIC32CM5164LE00100-I/PF is purpose-built for ultra-low-power IoT. The Microchip 60001615E family datasheet describes SleepWalking peripherals that monitor events while the CPU remains asleep, deep-sleep currents in the low microampere range, and active-mode efficiency of 2.64 CoreMark/MHz. These features make it a strong fit for battery-powered sensor nodes requiring years of operating life on a single coin cell.

What package does the PIC32CM5164LE00100-I/PF come in?

The PIC32CM5164LE00100-I/PF ships in a 100-pin TQFP (Thin Quad Flat Pack), measuring 14x14 mm with 0.5 mm pitch and a 1.0 mm nominal package height. The 'PF' suffix per Microchip ordering nomenclature designates the 100-TQFP package, providing generous GPIO (up to 84) and full peripheral exposure for complex multi-bus designs without external IO expanders.

Where can I buy the PIC32CM5164LE00100-I/PF online?

What is the difference between PIC32CM5164LE00100-I/PF and PIC32CM5164LS60100-I/PF?

The PIC32CM5164LE00100-I/PF and PIC32CM5164LS60100-I/PF differ in operating voltage range and memory configuration: the LE00 variant runs from 1.62 V to 3.63 V while the LS60 variant requires 2.0 V to 3.63 V. Per the Microchip 60001615E family datasheet, the LS60 sub-family additionally integrates a cryptographic security module, whereas the LE00 focuses on ultra-low-power touch and analog integration with the same 512 KB Flash and 64 KB SRAM.

When should I choose PIC32CM5164LE00100-I/PF over PIC32CM1216MC00048T?

Choose the PIC32CM5164LE00100-I/PF when your design needs 512 KB Flash, 64 KB SRAM, and a 100-pin TQFP with up to 84 GPIO - ideal for complex multi-bus IoT hubs. Choose the PIC32CM1216MC00048T instead if your design fits in 128 KB Flash with a smaller 48-pin package and you need the motor-control-specific peripherals of the PIC32CM MC family. Both share Cortex-M23 but target different application envelopes.

Can I replace PIC32CM5164LE00100-I/PF with a PIC32CM2532LS60100-I/PF?

No direct drop-in replacement is possible between PIC32CM5164LE00100-I/PF and PIC32CM2532LS60100-I/PF because their Flash densities differ (512 KB vs 256 KB) and operating voltage ranges differ (LE00 1.62-3.63 V vs LS60 2.0-3.63 V). Both share the 100-pin TQFP footprint, so if your firmware fits in 256 KB and your supply meets 2.0 V minimum, the LS60100 is a compatible alternate in the same package.

What is the best drop-in replacement for PIC32CM5164LE00100-I/PF?

The best drop-in replacement for the PIC32CM5164LE00100-I/PF in the same 100-pin TQFP package is the PIC32CM5164LS60100-I/PF from the same Microchip family, offering identical 512 KB Flash, 64 KB SRAM, and pinout but with cryptographic hardware and a 2.0-3.63 V supply. If lower Flash is acceptable, the PIC32CM2532LS60100-I/PF (256 KB Flash) shares the same footprint for footprint-compatible downsizing.

Руководство по выбору

Choose the PIC32CM5164LE00100-I/PF when you need a 32-bit Cortex-M23 MCU with 512 KB Flash, 64 KB SRAM, and up to 84 GPIO in a 100-TQFP, and your application can run from 1.62 V to 3.63 V (i.e., you want direct battery or 1.8 V regulator compatibility). Choose the PIC32CM5164LS60100-I/PF instead if you need integrated cryptographic hardware or can tolerate the 2.0 V minimum supply. Choose the PIC32CM2532LS60100-I/PF if your firmware fits in 256 KB Flash and you want cost savings with the same 100-TQFP footprint. For designs targeting -40C to +125C operation (under-hood automotive, outdoor industrial), select the -E/PF temperature grade variant. Same-brand alternatives are preferred first; cross-brand Cortex-M23 MCUs at this Flash density do not share pinout and are not drop-in compatible.

Заметки по проектированию

Place a 100 nF ceramic decoupling capacitor within 5 mm of each VDD pin and a bulk 4.7 uF ceramic on the main supply rail. Per Microchip 60001615E family datasheet section on power considerations, the AVDD pin should be filtered through an L-C network (10 ohm + 100 nF) to keep analog reference noise below the 12-bit ADC LSB. Use a star-ground topology with the MCU's VSS pin as the central reference for low-noise analog measurements.

The 100-TQFP at 0.5 mm pitch requires 4-layer PCB with a continuous ground plane under the IC for thermal dissipation and EMC. Per JEDEC JESD51, theta_JA for the 100-TQFP is approximately 50 C/W, so at 48 MHz active current draw the junction-to-ambient rise stays well below 30 C - no heatsink needed. Route SERCOM differential pairs (SPI CLK/MOSI) with matched lengths within 5 mm to avoid setup/hold violations at 48 MHz.

Do not leave unused GPIO floating - configure them as analog inputs with pull-up disabled to prevent parasitic current in deep-sleep modes (estimated 1-5 uA per floating pin). Per Microchip errata, certain PTC Y-lines on revision A silicon can interfere with ADC sampling; check the device marking and revision status in MPLAB X before committing to PCB layout. Always include a 10 kohm pull-up on the RESET pin even if not externally driven, to prevent spurious resets during power-up ramp.

For SERCOM SPI running above 24 MHz, add 33 ohm series-termination resistors at the MCU end of CLK and MOSI traces to dampen ringing. The 100-TQFP lead inductance is approximately 1-2 nH per pin; for long PCB traces (>50 mm) this can cause overshoot. The internal SERCOM peripheral has configurable drive strength - set to high for signals above 24 MHz, normal for lower speeds to reduce EMI.
