It is designed for high-speed repetitive computation and digital control, sharing pin compatibility with the dsPIC33F family of devices and using a 16-bit modified Harvard CPU that supports a 24-bit instruction word with variable-length opcode fields. The 'E' suffix indicates the extended industrial temperature grade of -40C to +125C. A PIC24H 16-bit microcontroller is a member of Microchip's 16-bit MCU family built on a modified Harvard architecture. It combines a 16-bit data path with a 24-bit instruction path, which improves code density for C compilers while supporting DSP-style addressing modes. PIC24H devices sit in the hierarchy MCU -> 16-bit MCU -> PIC24H family -> microcontroller -> embedded processor, and they target applications requiring deterministic real-time control at moderate clock rates without the cost of higher-performance 32-bit parts. Key features include 21 digital I/O pins with peripheral pin select (PPS) functionality, 5V-tolerant inputs, 4 mA sink/source capability, and open-drain outputs capable of pulling up to 5V. The device integrates three 16-bit timers (pairable into one 32-bit timer), two output compare modules, an input capture module, two UART, SPI, and I2C peripherals, a 10/12-bit ADC, and a 16-bit comparator. The PPS block remaps most digital peripherals to a wide choice of pins, simplifying PCB routing and BOM consolidation. The 40 MIPS core, hardware multiplier, and zero-overhead loop control make the PIC24HJ32GP204-E/PT suitable for digital control loops, sensor signal processing, and communication bridges. Its instruction set is optimized for compiled C, which lowers firmware development cost versus legacy 8-bit PIC architectures while retaining Microchip's ecosystem of MPLAB X IDE, MPLAB XC16 compiler, and dsPIC/PIC24 plug-in modules. Typical applications include industrial sensor signal conditioning, motor control pre-drivers, HVAC fan and pump controllers, building-automation nodes, point-of-sale terminals, and medical instrumentation front-ends. The combination of 32 KB Flash, 2 KB RAM, and 5V-tolerant I/O enables direct interfacing to legacy 5V sensors and actuators without external level shifters. When designing with this part, verify that the chosen 44-pin TQFP footprint exposes the required VDD/VSS pair counts and the dedicated PGED/PGEC programming pins.

This makes it a versatile choice for embedded designs requiring both MCU control and DSP-capable signal processing on the same footprint. A PIC microcontroller is a programmable, low-cost integrated circuit based on a Harvard-architecture CPU with on-chip Flash, RAM, peripherals (UART, SPI, I2C, ADC, timers) that implements an embedded control system. The PIC24H family specifically delivers 16-bit data paths with up to 40 MIPS performance—roughly an order of magnitude faster than the 8-bit PIC16/PIC18 families—while staying in the same development ecosystem (MPLAB X IDE, XC16 compiler, ICD programmers). PIC24H sits within the broader taxonomy: microcontroller -> embedded MCU -> semiconductor. Key features of the PIC24HJ32GP204-I/PT include 35 I/O pins, three 16-bit timers (which can pair into one 32-bit timer), two UART modules, two SPI interfaces, one I2C interface, a 10/12-bit ADC with up to 13 channels, and a 16-bit input capture / output compare peripheral set.

At the architectural level, the device uses a 16-bit modified-Harvard core with a hardware multiply-accumulate (MAC) block (inherited from dsPIC) and zero-overhead looping, enabling efficient DSP-style algorithms such as FIR/IIR filtering, motor control PWM generation, and real-time control of three-phase inverters. The 32 KB self-programmable Flash and 2 KB SRAM are sufficient for many real-time control firmware builds, while peripheral pin-select remapping eases IO routing. Typical applications include industrial motor control (BLDC/PMSM), digital power conversion (SMPS), advanced sensor interfacing, audio processing, and general-purpose 16-bit embedded control. The 16-bit ADC and PWM pairs also suit digitally-controlled lighting and uninterruptible power supplies (UPS). Design tip: ensure that MCLR is pulled high through a 10 kohm resistor and that AVDD/AVSS are tied to VDD/VSS with a ferrite bead + decoupling capacitor for best ADC noise performance. Decoupling should include a 100 nF per VDD pin and a bulk 10 uF near the package.

It operates from a 3.0V to 3.6V supply, runs at up to 40 MHz internal oscillator, and integrates 4KB RAM plus 1KB EEPROM-like data Flash. The device is tape-and-reel packaged ('T' suffix) in the -40C to +85C industrial temperature range ('-I'), and ships in the 'ML' 44-VQFN-EP land pattern. What is a PIC24H microcontroller? A PIC24H is a 16-bit modified-Harvard MCU from Microchip, sitting in the hierarchy: PIC24H -> PIC24 family -> 16-bit MCU -> microcontroller -> embedded processor. PIC24H devices target high-speed control loops, DSP-style math, and motor/lighting/Power Conversion control, and are pin-compatible with the dsPIC33F family so designers can migrate from a MCU-only solution to a full DSP solution by swapping silicon with no PCB change. The 40 MIPS throughput lets a single device execute PID, PLL, and field-oriented-control software with comfortable margin.

Architecturally the part uses a 16-bit data path with a 24-bit instruction word, single-cycle MAC via the DSP engine, a 16 x 16-bit register file, and zero-overhead looping hardware. DMA is not present on this 32 KB flash sub-family (it appears on the larger PIC24HJ128/HJ256 variants), so high-bandwidth peripheral use cases depend on the 4 KB RAM and tight ISR coding. The CPU supports 16 x 16 signed fractional multiplication in one cycle, which is what enables the 40 MIPS figure and the family name 'H' (high performance). Typical applications for the PIC24HJ32GP204T-I/ML include AC-DC and DC-DC Power Conversion digital control loops, BLDC/PMSM/Stepper motor control FOC firmware, LED lighting drivers with DMX or DALI, Industrial sensor conditioning with CTMU capacitive touch, USB device firmware stacks via the on-chip full-speed USB-less architecture (use external transceiver), and AEC-Q100 demanding General-purpose 16-bit control where 8-bit MCUs run out of headroom. When designing with this device, pay close attention to the 3.0V to 3.6V rail - the part is NOT 5V tolerant on most I/O. Use the internal 7.5 MHz FRC with PLL to generate the 40 MHz system clock, and always provide the exposed pad thermal pad with 0.1 mm thermal vias for 28 C/W theta_JA performance. Place a 10 uF plus 0.1 uF decoupling pair within 5 mm of VDD/LDO pins. The PIC24HJ32GP204T-I/ML is an active production status part, available at major distributors with multi-thousand-piece stock.

PIC24HJ32GP302T-I/SO

PIC24HJ32GP302T-I/SO - 16-bit 40 MIPS MCU, 32KB Flash | Microchip

The Microchip PIC24HJ32GP302T-I/SO is a 16-bit microcontroller from the PIC24H family, delivering 40 MIPS performance at 40 MHz, integrating 32 KB Flash program memory (11K x 24 words) and 4 KB RAM in a 28-pin SOIC package with industrial -40C to +85C temperature range. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O. The 16-bit class sits between 8-bit MCUs and 32-bit MCUs in the embedded hierarchy: 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. PIC24H parts use a modified Harvard architecture with a 16-bit datapath, 24-bit instruction word, and a 16 x 16 hardware multiplier that completes a multiply in one cycle - giving the 40 MIPS figure. Key differentiating features include 21 remappable I/O pins (5V-tolerant with selectable open-drain and internal pull-ups), three 16-bit timers that can be paired into one 32-bit timer, two output compare modules, an input capture module, a 12-bit ADC with up to 10 channels (the JLCPCB listing references both 10-bit and 12-bit ADC modes - the PIC24HJ32GP302 is 12-bit ADC with 1 MSPS, while the PIC24HJ32GP304 variant is 10-bit), and two UART/SPI/I2C modules plus a 40 MHz device tree.

When designing with this MCU, ensure the 3.0V to 3.6V supply is decoupled with a 10uF + 0.1uF pair at VDD/AVDD pins. Note that the SOIC-28 package exposes 21 GPIO but the die has more peripheral channels - use Peripheral Pin Select (PPS) to map functions to physical pins. Migration from PIC24HJ32GP202 (no PPS, 20 pins fewer) requires remapping, but migration to PIC24HJ32GP304 changes the ADC to 10-bit - verify before substituting.

PIC24HJ32GP304-E/PT - 40 MIPS 16-bit MCU, 32KB Flash, 44-TQFP | Microchip

The Microchip PIC24HJ32GP304-E/PT is a 16-bit microcontroller from the PIC24H family, delivering 40 MIPS CPU performance at up to 40 MHz, with 32 KB of Flash program memory and 4 KB of RAM, housed in a 44-pin TQFP (PT) package. It integrates a DMA controller, three 16-bit timers that can be paired into a 32-bit timer, two output capture modules, and a peripheral set tailored for high-speed control loops and DSP-style signal conditioning. What is a 16-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of peripheral interfaces (timers, ADC, communication ports). The PIC24H sits in the 16-bit MCU category — a step above 8-bit MCUs in arithmetic throughput and code density, and a step below 32-bit MCUs in raw performance. Within the taxonomy, PIC24H belongs to: microcontroller -> 16-bit MCU -> PIC24 family -> PIC24H sub-family -> digital signal control / motor control class. It is engineered for applications that demand deterministic, repetitive computation at low cost. Key features of the PIC24HJ32GP304-E/PT include: 32 KB (11K x 24) Flash, 4 KB RAM, 21 general-purpose I/O pins, an integrated 10/12-bit ADC with up to 13 channels, two UART, two SPI, one I2C, and a DMA controller with 8 channels. The “-E” suffix designates the -40°C to +125°C extended operating temperature range, which is important for industrial and automotive under-hood applications. The device runs from a 3.0 V to 3.6 V supply and is pin-compatible with the dsPIC33F family. The architecture is built on a modified Harvard structure with a 16-bit datapath, 24-bit instruction words, and a single-cycle 16x16-bit hardware multiplier. This combination delivers deterministic 40 MIPS throughput, which is well-suited to digital control loops running at 10-20 kHz where 8-bit MCUs would saturate. The DMA controller offloads data movement between peripherals and memory, freeing the CPU for compute. Typical applications include industrial motor control (BLDC, PMSM, FOC), power conversion (digital PFC, LLC resonant converters), sensor signal processing, and general-purpose embedded control where C code portability and a robust toolchain (MPLAB X, XC16) are priorities. Design considerations: the 44-pin TQFP has an exposed thermal pad that should be soldered to a ground pour to reduce thermal resistance. Decoupling requires 100 nF ceramic capacitors placed as close as possible to every VDD/VSS pair, plus a bulk 10 µF tantalum or ceramic capacitor on the main rail. For applications that exceed 30 MIPS sustained throughput, ensure VDD does not droop below 3.0 V under peak transient load.

What is a 16-bit microcontroller? A 16-bit MCU is a single-chip computer with a 16-bit data path, instruction word, and ALU, sitting in the taxonomy: microcontroller -> embedded MCU -> 16-bit MCU -> digital signal controller. Compared with 8-bit MCUs, 16-bit parts offer higher code density, faster arithmetic, and richer peripherals; compared with 32-bit MCUs, they typically cost less and consume less power. The PIC24H uses a modified Harvard architecture with a 24-bit instruction word and 16-bit data path, an unusual combination that increases code density while preserving deterministic real-time interrupt behavior. Key features of the PIC24HJ64GP202T-I/MM include 21 general-purpose I/O pins, multiple 16-bit timers, a 12-bit A/D converter with up to 10 channels, motor-control PWM, UART, SPI, I2C, and a DMA controller that offloads data movement from the CPU. The 64 KB flash supports self-programming and is rated for >10,000 erase/write cycles, while the 8 KB SRAM is sufficient for full TCP/IP stack plus application buffer memory. Technical depth: the 16-bit PIC24H core uses a 5-stage pipeline and a 16 x 16-bit hardware multiplier that completes a 16x16 multiply in one cycle. Combined with the 40 MHz maximum clock this yields 40 MIPS sustained throughput. DMA-capable peripherals can move ADC samples, SPI/I2C traffic, and PWM updates without CPU intervention, freeing the core for control loops. Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion (SMPS, PFC), sensor signal processing, embedded industrial controllers, and consumer devices needing precise real-time control. Pin compatibility with dsPIC33F devices means designers can migrate to DSP extensions when they add FFT, FIR, or PLL-driven algorithms. When designing with this part, remember the 28-QFN (MM) package has an exposed thermal pad that must be soldered to the ground plane for proper electrical performance and heat dissipation. The industrial temperature grade (-40C to +85C) is denoted by the I suffix in the ordering code. This page synthesizes distributor pricing, drop-in alternative MPNs, and practical PCB design notes not found in the manufacturer datasheet alone, helping procurement and embedded engineers evaluate the PIC24HJ64GP202T-I/MM against other PIC24H and competing 16-bit MCU options.

A 16-bit microcontroller (MCU) is a microprocessor-on-a-chip that integrates a 16-bit CPU core, program and data memory, peripherals, and I/O on a single die. The PIC24H family uses a modified Harvard RISC architecture with 16-bit wide data paths and a 24-bit instruction word, sitting in the hierarchy between 8-bit PIC MCUs and 32-bit MIPS-based PIC32 devices. The 40 MIPS performance class is typically applied to high-speed repetitive control loops, motor control, and digital signal preprocessing where 8-bit MCUs run out of headroom but a full DSP is unnecessary. Key features include a 16-channel 10/12-bit ADC (configurable), three 16-bit timers (pairable to one 32-bit), two output compares, two UART/SPI/I2C capable EUSART/ECAN modules, a 4-channel DMA controller, an 8-bit parallel master port, and a charge time measurement unit (CTMU) for capacitive touch sensing. The automotive -E temperature grade and AEC-Q100 qualification make this variant a direct fit for under-hood and cabin electronic control units. Architecturally, the PIC24HJ64GP204 implements a single-cycle hardware multiplier, a 16x16-bit working register array, and a 23-bit program counter. Code execution at 40 MHz completes most instructions in one cycle, giving deterministic interrupt latency suitable for hard-real-time control. The DMA controller offloads peripheral-to-memory transfers, freeing the core for control algorithms. Typical applications include automotive body control modules, HVAC damper actuators, sensor interface hubs, industrial PLC I/O cards, BLDC motor control sensor interfaces, and consumer appliances with capacitive touch user interfaces. The 8 KB SRAM accommodates modest protocol stacks such as CAN and LIN. When designing with this device, ensure the 3.0-3.6 V supply is tightly regulated, allocate a 4.7uF-10uF decoupling network near VDD/AVDD pairs, and reserve the MCLR pin for a proper reset supervisor. The E variant ships in 44-TQFP only, so verify your PCB land pattern matches.
