PIC24EP128GP202T-E/MM - 16-bit 70 MIPS MCU, 128KB Flash, 28-QFN | Microchip
MPN: PIC24EP128GP202T-E/MM ✓ Hoạt độngPIC24EP128GP202T-E/MM Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as timers, ADC, communication interfaces, and I/O ports. PIC24E devices belong to the 16-bit DSC (Digital Signal Controller) family, positioned in Microchip's portfolio between the 8-bit PIC16/PIC18 architectures and the 32-bit PIC32 families. PIC24E parts add DSP-grade MAC instructions, advanced analog peripherals, and higher clock rates than the PIC24F predecessors.
Key features of the PIC24EP128GP202 include a 16-bit wide data path, 70 MIPS performance from a 70 MHz system clock, dual 10-bit/12-bit capable ADC channels, up to six 16-bit timers, peripheral trigger generator (PTG), op amps, and CTMU (Charge Time Measurement Unit) for capacitive touch and current measurement. AEC-Q100 qualification and the extended -40C to +125C operating range are explicit advantages of the E/MM temperature/grade suffix combination.
The architecture combines a Harvard bus with on-chip 32x16 hardware multiply, providing deterministic execution needed for motor-control loops and real-time DSP filtering. The PIC24E instruction set adds DO and REPEAT hardware loops, MAC (multiply-accumulate) for DSP kernels, and bit-field instructions for efficient peripheral control. With 128 KB Flash (43K x 24 words) and 16 KB SRAM, the part targets mid-range firmware footprints typical in body electronics, sensor fusion, and audio processing.
Typical applications include automotive body and comfort modules, sensor interface boards, motor control pre-drivers, low-cost digital power conversion, and industrial sensor hubs. The AEC-Q100 grade also extends use to under-hood and chassis ECUs when paired with proper external protection.
When designing with this MCU, ensure a low-impedance ground return under the exposed pad to meet thermal and EMI expectations, and configure the alternate I/O mapping table early to avoid pin conflicts. Decoupling should follow Microchip's 100 nF per VDD + bulk 10 uF guidance.

Ghi chú thiết kế
Power the PIC24EP128GP202T-E/MM from a low-noise 3.3V regulator; Microchip recommends placing a 100 nF decoupling capacitor close to each VDD/AVDD pair, with a single 10 uF bulk capacitor near the package. The exposed thermal pad must be soldered to a clean ground plane to meet thermal and EMI expectations. Estimated: idle current is typically <30 mA at 70 MIPS with all peripherals disabled, dropping to single-digit uA in deep sleep.
For the 28-VQFN (6x6 mm) package, use a 0.4 mm pitch land pattern with at least 8 thermal vias under the exposed pad stitching to the inner ground plane. Place decoupling capacitors within 3 mm of their respective supply pins, and route the analog AVSS/AVDD pair as a Kelvin connection to the supply ground to avoid ADC offset errors. Avoid routing high-speed digital signals under the exposed pad to preserve ground integrity.
Do not exceed 3.6V on any VDD pin; the PIC24EP128GP202T-E/MM does not have 5V tolerance on digital I/O. Ensure the MCLR pin is pulled high through a 10 kohm resistor for normal operation; leaving MCLR floating prevents startup. The PIC24E PPS (Peripheral Pin Select) feature lets remappable peripherals be assigned to many I/O pins, but locked assignments must be unlocked via CFGCON before PPS registers accept writes - a frequent source of mysterious peripheral failures for first-time users.
