PIC24HJ64GP210AT-I/PT Overview
A 16-bit microcontroller (MCU) is a single-chip processor that uses a 16-bit-wide data path, registers, and ALU, providing higher computational throughput than 8-bit MCUs while retaining deterministic real-time interrupt behavior. The PIC24H architecture positions itself in Microchip's broader hierarchy as: MCU -> 16-bit MCU -> dsPIC33F/PIC24H family -> digital signal controller with peripherals. It is engineered for high-speed repetitive computations and closed-loop control, complementing rather than replacing 8-bit PIC10/12/16 families and 32-bit PIC32 families.
Key features include an integrated 16-channel 10-bit ADC with 500 ksps throughput, dual analog comparators, two UART modules, two SPI ports, and an I2C interface. The device also provides eight 16-bit timer/counters, a hardware Real-Time Clock and Calendar (RTCC), a 16-bit Parallel Slave Port, and a 16-bit Parallel Master Port. DMA with eight channels accelerates data movement without CPU intervention, and the peripheral pin select (PPS) system remaps digital functions to multiple I/O pins for layout flexibility.
The PIC24HJ64GP210A silicon uses a Harvard architecture with separate 16-bit data paths and 24-bit instruction words, supported by 8 KB of RAM and 16 KB of auxiliary Flash for data storage. Its wide range of communication peripherals and 32 KB of dual-ported SRAM make it suitable for human-machine interface, motor control, and process control designs that demand deterministic interrupt latency and high code density.
Typical applications include industrial motor control (BLDC, PMSM, and stepper drives), digital signal processing front-ends (audio, biometric, and sensor conditioning), HVAC and building automation controllers, automotive body and chassis subsystems, and embedded control in medical instrumentation. The 100-pin TQFP provides ample I/O for multi-channel feedback loops and external memory expansion.
When designing with this device, ensure the 3.0-3.6 V core supply is low-noise, since the ADC reference derives from VDD/VSS. Decouple each VDD/VSS pair with 100 nF and bulk 10 uF capacitors, and route the analog AVdd/AVss pair separately. Allocate a JTAG header (TCK, TMS, TDI, TDO) to every prototype board for ICD-3 / REAL ICE in-circuit debugging and programming.

Typical Applications
PIC24HJ64GP210AT-I/PT is suitable for 6 applications: Industrial BLDC Motor Control, Digital Signal Processing Front-End, HVAC and Building Automation Controller, Automotive Body and Chassis Subsystems, Embedded Medical Instrumentation, Industrial Process Control PLCs.
Industrial BLDC Motor Control
The PIC24HJ64GP210AT-I/PT's 40 MIPS CPU, 9 timer/counters, dual analog comparators, and 10-bit 500 ksps ADC make it a strong fit for sensorless BLDC and PMSM motor drives. Its 8-channel DMA streams ADC samples into RAM without CPU load, freeing cycles for Field-Oriented Control math at 20 kHz PWM rates. Engineers typically use the TQFP-100 footprint to keep Hall-sensor, back-EMF, and shunt-amplifier inputs co-located on the same PCB. With 64 KB Flash the device holds vector-control firmware plus an RTOS task scheduler and still leaves room for customer-specific tuning tables.
Recommended
Digital Signal Processing Front-End
Audio, biometric, and vibration sensor conditioning benefit from the PIC24HJ64GP210AT-I/PT's 40 MIPS throughput and 8-channel DMA engine. DMA transfers samples between the 10-bit ADC and a 16-bit FFT routine in RAM, sustaining deterministic 1 ms loop times without CPU intervention. The Harvard architecture with 16-bit data path accelerates sample-rate conversion versus 8-bit MCUs, and 8 KB RAM supports 512-point FFT buffers. The TQFP-100 footprint exposes the full analog pin set for multi-channel transducer arrays, making it a clean fit for portable DSP data acquisition.
Recommended
HVAC and Building Automation Controller
HVAC systems, building-automation panels, and thermostat hubs leverage the PIC24HJ64GP210AT-I/PT's mix of communication peripherals: 2 UART, 2 SPI, 1 I2C, plus PWM for fan and damper control. The 10-bit ADC monitors multiple temperature and humidity sensors, while 8 KB RAM supports Modbus and RS-485 buffering for BACnet gateways. Industrial -40C to +85C temperature grade ensures long-term reliability in unconditioned plant rooms. The TQFP-100 footprint allows combined power-line communication, LED driving, and display interfacing on a single board.
Recommended
Automotive Body and Chassis Subsystems
The PIC24HJ64GP210AT-I/PT's 16-bit processing and -40C to +85C industrial temperature grade suit body controllers, lighting modules, and seat controllers in automotive environments. Its PWM channels drive LED matrices and DC motors, while UART and SPI connect to LIN transceivers and dashboard displays. The Harvard architecture delivers deterministic interrupt latency for CAN-style message handling when paired with an external CAN controller. Although not AEC-Q100 qualified, the silicon revision A design win enables long-life automotive deployments in non-safety applications.
Recommended
Embedded Medical Instrumentation
Patient monitors, infusion pumps, and portable diagnostic devices use the PIC24HJ64GP210AT-I/PT for deterministic low-latency sensor sampling. Its 10-bit ADC with DMA keeps the CPU free to run safety-check loops at fixed 1 ms intervals, while 64 KB Flash holds validated firmware plus a small RTOS. The wide 3.0-3.6 V supply range simplifies Li-ion power design, and the TQFP-100 footprint accommodates human-machine interface buttons and LCD drivers on the same PCB. For designs needing higher precision, an external MCP3201 12-bit ADC pairs cleanly with the MCU's SPI port.
Recommended
Industrial Process Control PLCs
Modular PLCs and process-control I/O cards use the PIC24HJ64GP210AT-I/PT to scan 16-32 analog inputs while driving relays and triac outputs. The 8-channel DMA offloads ADC scanning from the CPU, leaving headroom for ladder-logic or IEC-61131-3 interpreter runtime in 64 KB Flash. Dual UART ports handle RS-485 master/slave topology for fieldbus networks, and the SPI bus drives isolated digital outputs to high-voltage drivers. The TQFP-100 footprint also gives access to 85 I/O for screw-terminal breakouts typical of DIN-rail-mounted industrial controllers.

Key Differentiators
- Drop-in TQFP-100 upgrade doubles Flash memory (vs PIC24HJ128GP210AT-I/PT)
- Pin-compatible migration to DSP engine (vs dsPIC33FJ128GP710A-I/PT)
- Direct TQFP-100 part-number alternative at higher density (vs PIC24HJ256GP610AT-I/PT)
Design Notes
Place 100 nF ceramic decoupling on every VDD/AVDD pin within 5 mm of the package, plus a single 10 uF bulk cap on the supply rail. The ADC reference is derived from VDD/VSS, so a low-noise LDO (e.g. MCP1700) feeding VDD/AVDD is strongly recommended. Estimated: if ADC input impedance is 5 kohm and a 100 nF cap is used, the ADC will sample to 1/2 LSB within ~1.5 us at 500 ksps.
Route analog AVSS/AVDD pairs separately from digital grounds using a star-ground topology. Keep high-current PWM traces (motor drives, relay coils) physically isolated from the analog input cluster. The TQFP-100 footprint gives 0.4 mm pitch, so use NSMD pads with 0.2 mm soldermask expansion to minimize tombstoning on reflow. JTAG header (TCK/TMS/TDI/TDO) is required for ICD-3 in-circuit debugging.
At 40 MHz CPU and full I/O switching, the PIC24HJ64GP210AT-I/PT dissipates well under 500 mW; the TQFP-100 thermal pad (theta_JA approx 35 C/W) is sufficient without a heatsink. Estimated: at 250 mW dissipation, junction rises ~8.75 C above ambient, well inside the -40C to +125C Tj rating. For closed enclosures with poor airflow, derate by 30% and consider venting or a thermal via cluster under the package.
Compliance Information
RoHS and REACH compliant per Microchip product page. Industrial temperature grade -40C to +85C. Not AEC-Q100 qualified - for automotive safety-critical applications, refer to dsPIC33F AEC-Q100 qualified parts or PIC24/dsPIC33 with automotive suffixes.
