PIC24EP32GP202-I/MM - 16-bit 70 MIPS 32KB Flash MCU | Microchip
MPN: PIC24EP32GP202-I/MM ✓ Hoạt độngPIC24EP32GP202-I/MM Tóm tắt
A 16-bit microcontroller is a class of embedded processor that combines a CPU core, on-chip memory and integrated peripherals (ADC, timers, comms) on a single silicon die, sitting in the hierarchy MCU -> microcontroller -> embedded controller -> semiconductor. The PIC24E family in particular positions itself between 8-bit PIC16/PIC18 parts and 32-bit PIC32MX devices, offering higher code density and DSP-class throughput for signal-processing and motor-control tasks without migrating to a 32-bit toolchain.
Key features include 70 MIPS core throughput (70 MHz with 2-cycle instruction execution), hardware multiply/divide, a 16-channel 12-bit ADC with dedicated sample-and-hold, up to four UART, three SPI and two I2C peripherals, a Charge Time Measurement Unit (CTMU) for capacitive touch and current measurement, and a Peripheral Trigger Generator that sequences ADC and PWM events without CPU intervention. The 28-pin VQFN package provides a thermal pad for low theta_JA, important when the device is run near its 70 MHz maximum.
Architecturally, the PIC24EP32GP202 uses Microchip's 16-bit modified Harvard core with separate program and data buses, a 24-bit instruction word and a 16-bit DSP engine. The PTG and CTMU blocks allow deterministic, low-jitter peripheral timing and on-chip capacitive sensing, removing the need for external analog front-ends in many touch and measurement designs.
Typical applications include industrial sensor conditioning, capacitive touch human-machine interfaces, low-cost BLDC and stepper motor control, portable instrumentation, USB device controllers using the on-chip UART, and general-purpose 3.3V embedded control in appliances and IoT edge nodes. The PIC24EP32GP202 is the canonical member of the PIC24EP32GP20x family, with the -I/MM suffix selecting the 28-pin VQFN-S industrial-grade variant.
When designing with this part, note that the Flash endurance is specified at a minimum of 10,000 erase/write cycles per row and retention of greater than 20 years. Always provide a bulk 10 uF plus 0.1 uF decoupling network at VDD/VSS pairs and bond the exposed pad to a continuous ground plane for thermal and EMI performance.

Ứng dụng tiêu biểu
PIC24EP32GP202-I/MM phù hợp cho 6 Áp dụngs: Industrial Sensor Signal Conditioning, Capacitive Touch Human-Machine Interface, BLDC and Stepper Motor Control, Portable Instrumentation and Data Loggers, USB-to-UART Bridge and Protocol Converters, IoT Edge Nodes and Smart Appliances.
Industrial Sensor Signal Conditioning
The PIC24EP32GP202-I/MM is a strong fit for industrial sensor signal conditioning because it combines a 70 MIPS PIC24E core with a 12-bit ADC up to 16 channels and the on-chip CTMU block for ratiometric capacitive and current measurement. At a 3.3V rail, the MCU can sample multiple sensor inputs at > 1 MSPS aggregate while the DSP engine runs real-time filtering, linearization and temperature compensation. Compared with discrete op-amp + ADC solutions, integrating conversion and DSP on-die cuts board area and BOM cost. Use it with strain gauges, RTDs, thermocouples and 4-20 mA loop interfaces for factory automation nodes.

Capacitive Touch Human-Machine Interface
The CTMU (Charge Time Measurement Unit) and PTG (Peripheral Trigger Generator) on the PIC24EP32GP202-I/MM enable robust, low-cost capacitive touch HMI without external analog front-ends. The 70 MIPS core and 32 KB Flash handle up to ~20 touch buttons or a small matrix, with the 12-bit ADC scanning channels autonomously under PTG control, leaving the CPU free for comms and UI logic. Compared with a touch-only dedicated IC plus host MCU, integrating touch and control on the PIC24EP32GP202 reduces PCB area by ~30%. Industrial -40C to +85C rating supports appliance and rugged-panel use.
Được đề xuất
BLDC and Stepper Motor Control
The PIC24EP32GP202-I/MM drives small BLDC and stepper motors by combining high-resolution PWM (motor-control PWMs from the 16-bit timer block), 70 MIPS deterministic loop time, and fast 12-bit ADC sampling for back-EMF or current sensing. Its 3.0V to 3.6V supply, 28-pin VQFN-S footprint and exposed thermal pad suit compact motor boards; the same firmware scales up to PIC24EP64/128/256 variants without code rewrite. Compared with 8-bit PIC18 designs, the 16-bit DSP engine enables field-oriented control and sensorless commutation at > 20 kHz PWM. Ideal for fans, pumps, small appliances and e-bike sub-systems.
Được đề xuất
Portable Instrumentation and Data Loggers
The PIC24EP32GP202-I/MM is well-suited to portable data loggers because of its low-power sleep modes, 32 KB Flash for buffering, 4 KB SRAM for sample windows, and the 12-bit ADC accurate to within +/- 1 LSB typical. The CTMU can timestamp events at high resolution, and UART/SPI/I2C interfaces connect to external Flash, SD cards or BLE modules for extended logging. Industrial -40C to +85C rating supports outdoor deployments. Compared with 32-bit Cortex-M0 designs, this part delivers comparable throughput at lower cost and with Microchip's MPLAB X toolchain stability.

USB-to-UART Bridge and Protocol Converters
Using one of its four UART channels plus a USB-to-UART bridge IC, the PIC24EP32GP202-I/MM acts as a low-cost field-side protocol converter (RS-232/RS-485 <-> UART <-> SPI). The 70 MIPS core handles Modbus RTU, DMX512 or custom protocols in real time, and the 32 KB Flash accommodates full protocol stacks. The 28-pin VQFN-S keeps the BOM compact for inline converters. Compared with dedicated bridge chips, the PIC24EP32GP202 provides firmware flexibility for multi-protocol support and on-site upgrades.
Được đề xuất
IoT Edge Nodes and Smart Appliances
The PIC24EP32GP202-I/MM fits IoT edge nodes and smart appliances needing local decision-making, sensor fusion and a 3.3V rail. With 32 KB Flash for the application, 4 KB SRAM for queues, and a 12-bit ADC plus CTMU, it can run simple anomaly detection, scheduling and BLE/Wi-Fi provisioning through an external module. The PIC24E core at 70 MIPS handles TLS-style handshakes on small stacks. Compared with bare 8-bit PIC16 designs, the PIC24EP32GP202 provides 16-bit math and DSP, dramatically improving latency for local analytics at similar cost.

Ghi chú thiết kế
Power the PIC24EP32GP202-I/MM from a clean 3.3V rail within the 3.0V to 3.6V window specified in the Microchip datasheet. Place a 10 uF bulk tantalum or ceramic plus a 0.1 uF X7R decoupling capacitor within 5 mm of each VDD/VSS pair, and bond the exposed thermal pad to a continuous ground plane that is stitched with vias every 5-10 mm. Without proper decoupling, the ADC exhibits > 2 LSB noise at full-scale conversions.
Estimated: at 70 MHz with all peripherals active and 3.3V VDD, the PIC24EP32GP202-I/MM core current is roughly 30-40 mA. With the VQFN-S exposed pad soldered to a 1 sq inch ground pour on a 4-layer FR4 board, theta_JA is in the 35-40 C/W range, giving a junction temperature rise of approximately 10-15 C above ambient. No heatsink is required, but omitting the thermal pad bond will push theta_JA above 80 C/W and risk thermal shutdown in enclosed housings.
Route the ICSP pins PGED1/PGEC1 to a dedicated 2x3 header or test pad group, keeping the trace length under 50 mm and the lines impedance-matched to 33 ohm series resistors as recommended by Microchip. Keep the 12-bit ADC analog traces short and away from PWM/UART switching signals; add a ground guard trace around sensitive analog inputs. Failure to separate analog and digital return currents degrades ADC SNR by 6-10 dB.
Do not leave the MCLR pin floating - it must have a 10 kohm pull-up to VDD or be driven by the on-chip voltage supervisor, otherwise random resets will occur. Also note that the VQFN exposed pad (EP) is pin 29 and must be soldered to ground; leaving it unsoldered causes thermal runaway and reduces Flash programming reliability. Always erase-and-program the configuration bits in the same ICP session as the application Flash, otherwise the oscillator and watchdog settings revert to safe-but-unusable defaults.
