PIC32CM1216MC00032T-I/PT - 48MHz Cortex-M0+ MCU, 128KB Flash, 32-TQFP | Microchip
The Microchip Technology PIC32CM1216MC00032T-I/PT is a 32-bit ARM Cortex-M0+ microcontroller from the PIC32CM MC00 family, running at up to 48 MHz with 128 KB of Flash, 16 KB of SRAM, and 4 KB of EEPROM. It is housed in a 32-pin TQFP (7x7 mm) package and operates from 2.7V to 5.5V with 26 general-purpose I/O pins. The device is qualified for the -40C to +85C industrial temperature range and targets motor control and noisy-environment applications.
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), non-volatile data storage (EEPROM), and a rich set of peripherals (timers, ADC, communication ports). MCUs sit at the heart of nearly every embedded system, from sensor nodes to appliance controllers. The Cortex-M0+ core (from the broader ARM Cortex-M family of 32-bit processor cores) provides a Thumb-2 instruction set and deterministic interrupt response while consuming very little active and sleep current.
Key features of this part include a 48 MHz maximum CPU clock, a 12-bit ADC, multiple SERCOM (Serial Communication) interfaces that can be configured as UART, SPI, or I2C, an advanced motor-control PWM peripheral (PWM with 24-bit resolution and complementary outputs with dead-band insertion), LIN support, and configurable logic cells. The integrated Cortex-M0+ core also enables the use of the standard ARM ecosystem: CMSIS drivers, middleware, and tools, while Microchip provides MPLAB X IDE, MPLAB Harmony, and the MCC pin manager.
From a technical perspective the PIC32CM MC00 family uses a single-cycle hardware multiplier, a Nested Vectored Interrupt Controller (NVIC), and the Microchip proprietary Peripheral Touch Controller (PTC) for capacitive sensing. The dual-bank Flash with live update support allows firmware upgrades without downtime, which is valuable in field-deployed industrial nodes. The 4 KB EEPROM emulated in Flash provides endurance and retention suitable for storing calibration, configuration, and runtime data.
Typical applications include BLDC and brushed DC motor drives, consumer appliances, industrial control boards, HVAC fan control, automotive body and convenience ECUs (LIN slaves), capacitive-touch user interfaces, and 5V-tolerant sensor hubs. The 5V-tolerant I/O and 2.7V-5.5V supply range also suit legacy 5V industrial designs where 3.8V-only Cortex-M0+ parts cannot be used directly.
When designing with this MCU, ensure the supply decoupling network includes at least one 100 nF ceramic capacitor per VDD pin placed as close to the IC as possible, plus a bulk 10 uF capacitor on the main rail. For motor-control layouts keep the PWM traces short, separate analog and power grounds, and place at least one local decoupling cap per MOSFET gate-driver supply pin.
