The Microchip Technology PIC24HJ128GP306-I/PT is a 16-bit PIC24H general-purpose microcontroller delivering 40 MIPS (51.2 MHz core clock with 1:1.6 PLL ratio capable of 70 MIPS equivalent) from a 128 KB (43K x 24) Flash program memory in a 64-pin TQFP (10x10 mm) package. The part integrates 8 KB SRAM and operates across an industrial -40C to +85C temperature range, while the silicon itself supports 3.0V to 3.6V single-supply operation. A microcontroller (MCU) is a single-chip computer that combines a CPU core, program memory (Flash/ROM), working memory (RAM), and a rich set of peripherals (timers, ADC, communication controllers, GPIO). The PIC24H family uses a 16-bit modified Harvard RISC architecture with a 24-bit instruction word, occupying the mid-performance tier between Microchip's PIC24F and dsPIC33F/DSP families. Within the broader taxonomy, MCUs sit below microprocessors in capability but above bare logic ICs in integration, providing standalone programmability for embedded systems. Key features of the PIC24HJ128GP306-I/PT include up to 53 general-purpose I/O pins, a 16-channel 12-bit ADC with 500 ksps conversion rate, two UART modules, two SPI ports, two I2C ports, an ECAN 2.0B controller, and a Parallel Master Port (PMP). The 64-pin TQFP footprint exposes the full peripheral set, making this the largest pin-count variant in the GP306 sub-family. The PIC24HJ128GP306 uses a 5-stage pipeline with single-cycle multiplication and hardware divide, achieving 40 MIPS sustained throughput. Its peripherals are routed through a Peripheral Pin Select (PPS) mapping engine, allowing flexible assignment of digital functions to physical I/O pins without package redesign - a critical flexibility advantage over older fixed-pin PIC microcontrollers. Typical applications include industrial motor drives, power-conversion control loops, HVAC fan/pump controllers, building-automation nodes, automotive body and chassis ECUs, and CAN-connected sensor clusters where the on-chip ECAN 2.0B and 12-bit ADC simplify BOM and firmware development. When designing with this device, allocate sufficient PCB area for the 64-pin TQFP land pattern and follow Microchip's recommended decoupling scheme: a 10 uF bulk capacitor plus 0.1 uF ceramic per VDD/VSS pair. Firmware portability across the PIC24H/dsPIC33F families is a strong advantage for designers planning product variants. This page synthesizes distributor pricing, drop-in alternatives within the same 64-pin TQFP footprint, and practical design notes that complement the manufacturer datasheet. The 64-pin TQFP land pattern is shared across the entire PIC24HJ12xGP30x and PIC24HJ12xGP31x families, simplifying PCB reuse across product variants and firmware revisions.

The PIC24H family uses Microchip's enhanced 16-bit modified Harvard architecture with a 24-bit instruction word, placing it in the broader taxonomy: microcontroller -> embedded processor -> semiconductor device. These MCUs target deterministic real-time control where 8-bit devices lack throughput and 32-bit devices over-spend on cost and power. Key features include a hardware multiplier for single-cycle 16x16 MAC operations, a 16-channel DMA controller, up to 21 I/O pins, four 16-bit timers/counters, and an internal oscillator. The 24-bit instruction path and 16-bit data path allow compact, high-code-density programs while still providing enough headroom for DSP-style signal processing at 40 MIPS. The CAN 2.0B peripheral makes the part attractive for industrial and automotive networks. Architecturally, the PIC24HJ128GP502 combines a 5-stage pipeline, deterministic interrupt latency, and bit-manipulation instructions. The part is pin-compatible with the dsPIC33F family, enabling code reuse for designs that may migrate to DSP-class signal processing. Code execution reaches 40 MIPS from a 40 MHz FRC or crystal oscillator source, while peripheral flexibility allows flexible timer/capture/PWM configurations. Typical applications include industrial control systems, sensor signal conditioning, motor control (BLDC/PMSM with external FET drivers), building automation, HVAC controllers, automotive body electronics, and medical instrumentation. The integrated CAN peripheral is especially useful in CAN-enabled sensor clusters and distributed I/O. Designers should pay close attention to the 3.3 V supply constraint and the need for proper decoupling near the AVDD/AVSS pins to achieve the 12-bit ADC performance. The wide-body SOIC footprint allows easy hand-soldering and rework during prototyping, while the T/R suffix on this variant indicates tape-and-reel packaging for SMT assembly lines. This page synthesizes real-time distributor stock and pricing, parametric drop-in alternatives drawn from the same PIC24H family and cross-brand equivalents, and practical PCB-layout and ADC design notes that complement the manufacturer datasheet.

The "-H" suffix denotes the High-temperature variant rated for -40C to +150C operation, while "PT" identifies the TQFP-44 package. It is built on a modified Harvard architecture with a 16-bit datapath and 24-bit instructions, providing excellent code density and deterministic interrupt latency for embedded control. 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 onto one die. Within the embedded-system taxonomy, the PIC24HJ128GP504 sits in the 16-bit MCU tier - a step above 8-bit MCUs in arithmetic throughput but below 32-bit Cortex-M devices in raw performance. It belongs to the PIC24H sub-family, which is pin-compatible with the dsPIC33F DSP-capable siblings, giving designers an upgrade path to DSP without board changes. Key features include 128 KB (43K x 24) self-programmable Flash, 8 KB SRAM, a 12-bit A/D converter with up to 13 input channels, two UART modules, two SPI modules, and a 16-bit timer/capture/compare/PWM block. The device operates from 3.0V to 3.6V and integrates a 4x PLL for flexible clocking from external crystals or oscillators. An on-chip DMA controller with 8 channels offloads data movement from the CPU, accelerating throughput for sensor arrays and communication stacks. Architecturally, the PIC24HJ128GP504 uses a 16-bit wide datapath with 24-bit instruction words, enabling single-cycle MAC operations on 16-bit data. The 5-stage pipeline and hardware multiply/divide unit deliver up to 20 MIPS at 40 MHz FOSC, while deterministic interrupt response (5-cycle latency) simplifies real-time control loops. The advanced analog block integrates sample-and-hold plus simultaneous sampling, supporting motor-control and power-conversion applications. Typical applications include industrial motor control (BLDC, PMSM, ACIM), sensor signal conditioning, digital power conversion, automotive body and chassis ECUs, and high-temperature downhole or under-hood instrumentation. The 150C rating makes it suitable for harsh-environment telemetry. The wide peripheral integration reduces external component count, shrinking BOM cost in volume production. When designing with this MCU, leverage the DMA controller to keep the CPU free for control loops and use the peripheral trigger mechanism for deterministic ADC sampling. For new designs, evaluate the -H temperature grade carefully - it is more expensive than the -I grade and may have longer lead times, so design prototypes with the -I variant and qualify the -H version for production.
