The Microchip Technology PIC24HJ128GP310T-I/PF is a high-performance 16-bit PIC microcontroller belonging to the PIC24H family, featuring a 40 MIPS modified Harvard architecture core and 128KB (43K x 24) of Flash program memory in a 100-pin TQFP (14x14 mm) package. Operating from a 3.0V to 3.6V supply, it integrates 16KB SRAM and a rich peripheral set including DMA controllers, PWM, UART, SPI, I2C, ADC, and a watchdog timer. The 'T' suffix denotes tape-and-reel packaging, and the 'I' suffix indicates the industrial -40C to +85C operating temperature range. A 16-bit microcontroller (MCU) is a programmable integrated circuit that combines a 16-bit CPU core, volatile RAM, non-volatile Flash memory, and on-chip peripherals into a single silicon die. Within the broader microcontroller taxonomy, the PIC24HJ128GP310 belongs to the PIC24H 'High-Performance' family, which sits between the PIC24F (low-power) and dsPIC33F (DSP-enhanced) families. It executes instructions at up to 40 MIPS (million instructions per second) using a modified Harvard architecture with separate program and data buses, enabling deterministic single-cycle execution. Key differentiating features include hardware DMA with up to 8 channels, 16-bit timers/capture/compare, a 12-bit ADC with 500 ksps throughput, USB 2.0 full-speed OTG, CAN 2.0B, and JTAG ICD debugging. The 128KB Flash supports 10,000 erase/write cycles typical, and the integrated 16KB RAM allows substantial data buffering. Compared with 8-bit PIC16/18 parts, the 16-bit core delivers 4-10x higher MIPS density for DSP-like signal processing in embedded control applications. Typical applications include industrial motor control (BLDC, PMSM, stepper), uninterruptible power supply (UPS) controllers, power-conversion feedback loops, medical instrumentation with USB or CAN connectivity, automotive body and chassis ECUs (non-safety), and consumer audio processing. The peripheral mix is particularly suited to real-time control loops where deterministic interrupt latency and DMA offload are required. When designing with this device, ensure the Vcap pin (pin 86 on TQFP-100) is connected to a 10 uF ceramic decoupling capacitor, as the internal core regulator requires external capacitance. Designers migrating to dsPIC33F for DSP gain code compatibility, or to PIC24F for lower power, should consult Microchip migration guides; the PIC24HJ family bridges both worlds.

It is part of the PIC24HJ128GPX02/X04 family of 16-bit microcontrollers with advanced analog peripherals, and is pin-compatible with the dsPIC33F family, allowing design portability between control-only and DSP-capable firmware. A 16-bit microcontroller (MCU) is a microprocessor optimized for embedded control with a 16-bit data path, native peripherals (ADC, timers, UART, SPI, I2C), and deterministic real-time interrupt handling. Microcontrollers sit within the broader hierarchy of microprocessors -> microcontrollers -> 16-bit MCU -> PIC24H family -> Power Management and Embedded Control. The 16-bit architecture provides a balance between 8-bit MCU simplicity and 32-bit performance, ideal for applications that need higher code density and math precision than 8-bit parts can offer without paying the cost of an MPU. Key features include a 16-bit modified Harvard architecture with single-cycle 16x16 multiplier, dual 40-bit accumulators (dsPIC compatible), 21 to 35 general-purpose I/O, an on-chip 12-bit A/D converter with up to 13 channels, multiple UART/SPI/I2C peripherals, and a wide operating voltage of 3.0V to 3.6V. The -H suffix designates the high-temperature automotive grade with operation from -40C to +150C, qualifying it for AEC-Q100 harsh-environment deployments. Technical depth: the PIC24HJ core runs at 40 MHz (10 MIPS/MHz) and includes a 16-element register file, hardware multiply/divide, and a deterministic interrupt controller with 5-cycle latency. The 44-QFN exposed pad (EP) lowers thermal resistance for higher-power applications by providing a direct heat path to the PCB. Typical applications include automotive body and chassis control, industrial motor control, sensor signal conditioning, LED lighting controllers, and consumer appliances. The wide I/O count and analog integration make it a strong fit for mixed-signal embedded designs. Design tip: the 44-QFN exposed pad must be soldered to a thermal land on the PCB with adequate thermal vias to meet the JEDEC EIA/JESD51 standard for junction-to-ambient thermal resistance; floating the EP causes device overheating and reliability failure.

Within the semiconductor hierarchy, the PIC24HJ128GP506A belongs to the 16-bit MCU class -> microcontroller family -> embedded processor category -> semiconductor IC. The "PIC24H" sub-family is Microchip's high-performance 16-bit tier, sitting above the cost-optimized PIC24F and below the dsPIC33F DSP-enhanced parts, making it well suited to closed-loop control loops, motor drive, and high-speed sensor interfacing. Key features include a 16-channel 12-bit ADC capable of 500 ksps conversion, up to eight PWM outputs with edge-aligned or center-aligned modes, two UART, two SPI and two I2C peripherals, and a 16-bit timer/counter bank. The device also exposes multiple DMA channels that offload data movement between peripherals and RAM, freeing CPU cycles for application logic. The wide 3.0V to 3.6V supply range, dual Watchdog Timer and Fail-Safe Clock Monitor support robust industrial deployments. The ICSP/In-Circuit programming interface enables in-field firmware updates without removing the device from the PCB. Typical applications include industrial motor control (BLDC/PMSM FOC), digital signal processing front-ends, multi-channel data acquisition, point-of-load system monitoring, and embedded control for medical and consumer appliances. The 64-VQFN package exposes up to 53 digital I/O pins, supporting parallel sensor buses and human-interface buttons/LEDs simultaneously. Pair the MCU with an external EEPROM or serial Flash for data logging, and use the integrated 12-bit ADC for transducer readout. When laying out the PCB, place the 64-VQFN exposed pad (EP) directly over a top-layer copper pour stitched with thermal vias to inner ground layers to keep junction temperature within the -40C to +85C industrial range. The PIC24HJ128GP506A-I/MR is pin-compatible with the PIC24HJ128GP306A-I/MR and PIC24HJ128GP306-I/MR variants, simplifying PCB reuse across the 128/64 KB Flash tiers.

PIC24HJ128GP506A-I/PT - 40 MIPS 16-bit MCU 128KB Flash TQFP-64
PIC24HJ128GP506A-I/PT

PIC24HJ128GP506A-I/PT - 40 MIPS 16-bit MCU 128KB Flash TQFP-64

The Microchip Technology PIC24HJ128GP506A-I/PT is a high-performance 16-bit PIC24H microcontroller delivering up to 40 MIPS at 3.3V, packaged in a 64-pin TQFP (10x10 mm). It integrates 128 KB of Flash program memory organized as 43K x 24 words, 8 KB of SRAM data memory, and a DMA controller for CPU-offload data movement. The device operates from a 2.0V to 3.6V supply and supports an industrial temperature range of -40C to +85C, making it suitable for harsh embedded environments. What is a 16-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O into one package. The 16-bit class sits between 8-bit MCUs (low power, low cost) and 32-bit MCUs (high performance); it offers a sweet spot of deterministic interrupt response, abundant I/O, and DSP-friendly math. Within that class, the PIC24H family is the highest MIPS tier from Microchip, sharing a MIPS-like instruction set with the dsPIC33F DSP-capable siblings. Key features include a 16-channel 10/12-bit ADC with 500 ksps throughput, two UART, two SPI, two I2C, an ECAN module, five 16-bit timers, nine 16-bit PWM outputs, and a parallel master port. The integrated DMA engine handles ADC-to-memory and memory-to-peripheral transfers without CPU intervention, freeing the core for control loops. Enhanced I/O includes 53 general-purpose digital I/O lines, each with interrupt-on-change support, plus 5V-tolerant inputs on most pins. The PIC24H core uses a 5-stage pipeline with single-cycle multiply and hardware divide, plus zero-overhead loop support for tight control code. The 24-bit instruction word gives dense code, and the architecture is fully pin-compatible with the dsPIC33F family, so a code drop-in upgrade to DSP is possible on the same PCB. Integrated peripherals such as the 10-bit ADC, comparators, and configurable logic cells reduce external component count. Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion, sensor signal conditioning, automotive body and chassis modules, and point-of-sale terminals. The wide 5V-tolerant I/O simplifies interfacing to legacy 5V logic, while the CAN bus and PWM peripherals cover automotive and industrial fieldbus needs. When designing with this part, plan the 3.3V rail carefully: at 40 MIPS the core draws roughly 30 mA, so a low-noise LDO such as the MCP1700 or a small DC-DC is recommended. Add 0.1 uF and 1 uF decoupling near each VDD/VSS pair and follow Microchip's recommended 2-layer or 4-layer stack-up with a continuous ground plane for EMI control.

The PIC24H family belongs to Microchip's broader PIC24F/dsPIC30F/dsPIC33F/PIC24H 16-bit MCU portfolio, which sits above 8-bit PIC10/12/16/18 devices in performance and below 32-bit PIC32 devices in code size. PIC24H MCUs are well-suited for motor control, digital power conversion, and high-speed sensor processing. Key features of this part include a 40 MHz maximum operating frequency (40 MIPS at the instruction cycle rate), 16 KB SRAM, 4 KB EEPROM, a 16-channel 10-bit/12-bit ADC, multiple SPI/I2C/UART peripherals, a Parallel Master Port, and a 16-bit timer/counter block. The modified Harvard architecture with a 16-bit wide datapath and 24-bit instructions enables efficient C-compiled code while keeping deterministic interrupt latency. Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion (PFC, LLC), sensor signal processing, and general-purpose embedded control. Compared with 32-bit Cortex-M0 alternatives at similar MHz, the PIC24HJ128GP506A delivers a richer DSP-friendly instruction set and tighter interrupt determinism, at the cost of a smaller ecosystem and less RAM. The wide -40C to +85C industrial range supports factory-floor deployment without additional qualification. When designing with this device, plan the power-rail decoupling around a 3.3V analog/digital supply pair, route the exposed pad to a continuous ground copper pour, and use the on-chip Peripheral Pin Select (PPS) feature to remap digital peripherals onto spare pins. Refer to Microchip application note AN1066 for migration paths from PIC24F/dsPIC30F devices, which share a pin-compatible footprint family.
