MPN: PIC32MM0064GPL028-E/SP ✓ Hoạt độngPIC32MM0064GPL028-E/SP Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (RAM), and programmable peripherals (ADC, PWM, timers, communication interfaces) on a single silicon die. Within the broader semiconductor taxonomy, an MCU is a subset of microprocessors and embedded processors that prioritizes deterministic real-time control over raw computation. The PIC32MM GPL family positions 32-bit MIPS performance with cost and power consumption that competes directly with mid-range 8-bit and 16-bit MCUs, while retaining the ARM Cortex-M0 ecosystem migration path for users needing code portability.
Key features include a 12-channel 12-bit ADC (selectable 10-bit mode), 2 analog comparators, 3 general-purpose timers, 8 PWM channels, and a Real-Time Clock Calendar (RTCC) for timekeeping. The device supports 2.0V to 3.6V operation with on-chip voltage regulation and eXtreme Low Power (XLP) sleep modes that drop quiescent current to 500 nA. Multiple communication peripherals include I2C, SPI, and UART, providing flexible connectivity for sensor and peripheral integration. The 28-pin SPDIP package suits through-hole prototyping, hobbyist projects, and legacy board designs that benefit from socketed or hand-soldered assembly.
Technical depth: the MIPS32 microAptiv UC core implements the microMIPS instruction set, a compressed form of MIPS32 that reduces code size by approximately 20-30% compared to standard MIPS32, while retaining deterministic interrupt latency suitable for real-time embedded control. The integrated 8 MHz internal oscillator with PLL provides flexible clocking, and peripheral pin select (PPS) allows remapping of digital functions to optimize PCB routing. The 12-bit ADC achieves 200 ksps with selectable 10-bit low-power mode, and the RTCC continues counting through deep sleep using an external 32.768 kHz crystal.
Typical applications include IoT sensor nodes, low-power wireless remote controls, battery-powered instrumentation, HVAC controllers, and consumer electronics with display interfaces. The combination of 64 KB Flash and 8 KB RAM supports substantial application code with comfortable headroom for protocol stacks, while the 12-bit ADC enables precision sensor measurements in industrial and medical monitoring contexts.
When designing with this part, verify that the SPDIP-28 footprint matches your mechanical assembly process; for surface-mount designs, the same silicon is available in SOIC-28, QFN-28, and 4x4 mm UQFN packages. The microMIPS core requires an MPLAB XC32 compiler with appropriate optimization flags, and the device is supported by MPLAB X IDE, MPLAB Harmony v3 framework, and the full suite of Microchip code configurators.

Ghi chú thiết kế
The PIC32MM0064GPL028-E/SP operates from 2.0 V to 3.6 V. For battery-powered designs, add a 1 uF ceramic decoupling capacitor on each VDD pin within 5 mm of the package and a 10 uF bulk capacitor on AVSS-referenced ground. In deep sleep, the device draws approximately 500 nA, but peripheral leakage through floating I/O can add several hundred nA. Configure unused pins as digital outputs (low) to eliminate leakage paths.
Place the 32.768 kHz RTC crystal (if used) within 5 mm of the SOSCO/SOSCI pins with guard traces connected to analog ground. Keep switching regulators, RF traces, and high-current signals at least 10 mm from the crystal to prevent injection of jitter into the RTCC. The OSC1/OSC2 pins should also be kept short and surrounded by a ground pour to minimize EMI coupling into the system clock.
Estimated: with PGC/PGD on RB0/RB1, those pins lose digital I/O function during in-circuit programming; route peripheral connections away or use alternate peripheral pin select (PPS) functions. The device operates at 3.3 V logic; interfacing 5 V signals requires level shifters or external protection resistors. The 12-bit ADC achieves specified linearity only when AVSS is a clean analog ground separate from noisy digital ground - use a star-ground topology at the MCU.
For SPDIP-28 hand-soldered prototypes, use a socket (e.g. DIP-28 machined-pin) to allow firmware updates without repeated thermal stress on the package. Production designs should migrate to SOIC-28 or UQFN-28 variants for PCB space savings; both are pin-compatible variants of the same silicon. Always include test points on VDD, VSS, and a UART TX/RX pair for in-circuit firmware update (bootloader) support.
