PIC24EP128GP202-H/SO - 16-bit 70 MIPS MCU, 128KB Flash | Microchip
MPN: PIC24EP128GP202-H/SO ✓ Hoạt độngPIC24EP128GP202-H/SO Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and peripherals on a single die. The 16-bit PIC24E family sits in the high-performance tier of Microchip's dsPIC/PIC portfolio: it offers higher MIPS, larger memory, and richer analog peripherals than the 16-bit PIC24F family, while costing less than the dsPIC33 DSP-capable siblings. The PIC24EP128GP202 specifically targets applications that need substantial code space (128 KB Flash) and ample SRAM (16 KB) for buffering, while remaining in a small-footprint 28-pin package.
Key features include 128 KB (43K x 24) self-programmable Flash, 16 KB SRAM, multiple 16-bit timers, configurable logic cells, and a 12-bit ADC with up to 1.1 Msps conversion rate. The integrated op amps and CTMU remove the need for many external analog components, allowing smaller BOMs in sensor-interface and signal-conditioning designs. Communication peripherals cover UART, SPI, I2C, and ECAN, supporting both point-to-point and networked embedded links.
Architecturally, the device uses a modified Harvard architecture with separate program and data buses, plus a 24-bit instruction word that allows single-cycle operations on data words larger than 16 bits. The PTG is a unique peripheral that lets the CPU offload complex timing and trigger sequences to hardware, freeing the core for application code and improving deterministic behavior in real-time systems.
Typical applications include automotive sensor conditioning, industrial motor control front-ends, building automation, LED lighting controllers, and portable medical instruments where AEC-Q100 qualification, integrated op amps, and the PTG simplify design. The -H suffix indicates the high-temperature (-40C to +150C) operating range suited for under-hood automotive and other harsh environments.
When designing with this part, ensure you use the latest MPLAB X IDE and XC16 compiler to access the PTG libraries and the integrated op amp configuration macros. Decoupling should follow Microchip's 28-pin SOIC reference layout, with a 100 nF plus a 10 uF bulk capacitor within 5 mm of the VDDCORE and VDD pins.

Ứng dụng tiêu biểu
PIC24EP128GP202-H/SO phù hợp cho 6 Áp dụngs: Automotive Sensor Signal Conditioning, Industrial Motor Control Front-End, Building Automation and HVAC Control, LED Lighting and Color-Mixing Controllers, Portable Medical Monitoring Devices, Smart Sensor Hub with CAN Connectivity.
Automotive Sensor Signal Conditioning
The PIC24EP128GP202-H/SO's AEC-Q100 qualification and -40C to +150C operating range make it ideal for under-hood automotive sensors such as pressure transducers, position sensors, and exhaust gas sensors. The integrated 12-bit 1.1 Msps ADC and on-chip op amps condition low-level sensor outputs before ADC conversion, eliminating external analog components and reducing BOM cost. The CTMU enables capacitance-to-digital conversion for proximity and level sensors. The Peripheral Trigger Generator (PTG) sequences ADC sampling and DMA transfers deterministically without CPU intervention, ensuring sensor samples align with the rotating engine crankshaft.

Industrial Motor Control Front-End
The PIC24EP128GP202-H/SO is well-suited as the front-end controller in industrial variable-frequency drives and servo drives, where its PTG coordinates multiple PWM channels, ADC triggers, and fault inputs with microsecond precision. The 70 MIPS core runs field-oriented control (FOC) math and CANopen or Modbus stack simultaneously. The ECAN peripheral connects to industrial fieldbuses for remote configuration, while the integrated op amps condition current-sense shunt amplifier outputs. Note that for full 3-phase PWM output consider the sibling PIC24EP128MC202 family variant.

Building Automation and HVAC Control
The PIC24EP128GP202-H/SO fits building-automation controllers such as VAV boxes, thermostats, and zone controllers, where the 128 KB Flash accommodates Modbus, BACnet, or KNX stack code along with application logic. Its UART, SPI, and I2C peripherals drive sensor expansion boards for CO2, humidity, and occupancy detection. The integrated CTMU simplifies touch-panel interfaces. The -H grade's wide temperature range supports unconditioned rooftop and basement installations where ambient temperatures swing widely across seasons.

LED Lighting and Color-Mixing Controllers
Architectural and stage lighting controllers use the PIC24EP128GP202-H/SO to drive multi-channel LED strings via PWM outputs while running DMX-512 or DALI receive stacks. The 16-bit PWM resolution provides smooth dimming curves down to 0.1 percent brightness steps, and the 70 MIPS core computes CIE color-mixing algorithms without flicker. The PTG sequences PWM phase shifts across channels to avoid simultaneous switching transients that would otherwise radiate EMI. AEC-Q100 qualification also opens opportunities in automotive interior-ambient lighting.

Portable Medical Monitoring Devices
Portable medical devices such as pulse oximeters, glucose meters, and wearable activity monitors use the PIC24EP128GP202-H/SO as the central processing and display controller, leveraging the integrated op amps to condition photodiode outputs from SpO2 sensors without an external analog front-end. The 12-bit ADC captures pulse-waveform samples at 1.1 Msps for accurate oxygen-saturation calculation. Low-power sleep modes and the 3.3 V single-supply operation extend battery life across multi-day monitoring cycles. AEC-Q100 qualification eases the path to ISO 13485-compliant designs.

Smart Sensor Hub with CAN Connectivity
Industrial smart-sensor hubs aggregate data from multiple field sensors and forward it to a master PLC or gateway over ECAN. The PIC24EP128GP202-H/SO's ECAN peripheral handles CAN 2.0B frame transmission, while multiple UART channels connect to RS-485 sensor arrays. The 128 KB Flash accommodates custom sensor calibration tables and linearization algorithms. The PTG coordinates cyclic sampling of all sensor channels within fixed time slots, maintaining deterministic latency that the master PLC can rely on for closed-loop control decisions.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor within 3 mm of every VDD pin and a 10 uF bulk capacitor near the IC. The PIC24EP128GP202-H/SO has separate AVDD/AVSS analog supply pins - place a dedicated 100 nF decoupling capacitor on AVDD to keep ADC measurements clean. If the analog and digital grounds are split, join them at a single point near the AVSS pin to avoid ground-loop noise in ADC measurements.
Route the analog input traces (AN0-AN9) as short as possible and keep them away from switching traces such as PWM outputs or ECAN bus lines. Use a ground pour on the top layer under the analog traces, with vias to the inner ground plane every 5 mm. The 28-pin SOIC has a generous pad pitch of 1.27 mm - this simplifies routing but watch the inner-pad spacing under fine-pitch BGA companions. Estimated: assuming a 50 mm x 50 mm 2-layer board, expect a 4-layer stack-up to be needed only if analog accuracy below 1 LSB at 1 Msps is required.
Do not assume the PTG is auto-initialized - it must be configured via the PTGCON, PTGQUEUE, and PTGT0LIM registers in MPLAB X with the XC16 compiler's PTG library functions. Configuring the PTG incorrectly leads to silent hardware stalls that look like CPU lockups. Also remember that the integrated op amps require their own configuration via the DAC and CMPCON registers before being usable as signal-conditioning stages.
