It comes in a 44-pin TQFP (10x10 mm) package with an industrial-grade -40C to +125C operating temperature range (the "E" suffix) and is qualified to AEC-Q100 standards for automotive applications. The device is part of the PIC24H family and is pin compatible with the dsPIC33F family of devices. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and peripheral interfaces (ADC, timers, communication ports) onto one silicon die. 16-bit MCUs like the PIC24H occupy the middle ground between 8-bit controllers (e.g., PIC16, ATmega) and 32-bit ARM Cortex-M devices, offering a balance of deterministic real-time performance, richer arithmetic, and code density for motor control, power conversion, and signal-processing applications. The PIC24H belongs to the broader taxonomy: 16-bit MCU -> MCU -> embedded processor -> semiconductor IC. Key features of the PIC24HJ128GP504-E/PT include: 128 KB (43K x 24) Flash, 8 KB SRAM, 40 MIPS performance from a 40 MHz system clock, 13-channel 12-bit ADC, 8-channel DMA, multiple UART/SPI/I2C interfaces, JTAG boundary scan, and an operating voltage range of 3.0V to 3.6V. The 16-bit modified Harvard architecture allows single-cycle MAC operations, accelerating DSP-style algorithms. The device uses a 16-bit modified Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. Its 40 MIPS throughput supports demanding control loops, while the 8-channel DMA engine offloads data movement between peripherals and RAM, freeing the CPU for computational tasks. The AEC-Q100 qualification extends the operating temperature range to +125C and ensures reliability under automotive stress conditions. Typical applications include BLDC and PMSM motor control (compressor, pump, fan), automotive body and chassis ECUs, digital power conversion (SMPS, PFC), industrial control loops, and sensor signal processing. The combination of 16-bit DSP throughput, automotive qualification, and PIC24H family pin compatibility with dsPIC33F makes it well suited for high-reliability embedded designs. A key design consideration is voltage supply: this MCU requires a 3.0V to 3.6V rail, and an external LDO or switching regulator is typically used to derive it from a 5V or 12V bus. Decoupling should follow Microchip's recommended layout guidelines, with 100 nF capacitors placed close to each VDD/VSS pair and a bulk capacitor at the supply input. This page synthesizes distributor pricing, pin-compatible same-family alternatives, and practical design notes beyond what is found in the manufacturer datasheet alone, supporting both engineering selection and procurement decisions.

PIC24HJ128GP506A-H/MR - 16-bit 20MIPS 128KB Flash MCU | Microchip

The Microchip Technology PIC24HJ128GP506A-H/MR is a 16-bit PIC24H microcontroller with 128 KB of Flash program memory and an 8 KB SRAM data space, delivering up to 20 MIPS throughput from a 40 MHz internal oscillator in a 64-pin VQFN (9x9 mm) package. According to the DigiKey listing, this device is rated for the AEC-Q100 automotive temperature range of -40C to +150C, making it suitable for under-hood and harsh-environment deployments. A 16-bit microcontroller (MCU) is a microprocessor with a 16-bit data path, registers, and ALU, sitting in the hierarchy: microcontroller -> embedded MCU -> semiconductor -> integrated circuit. The PIC24H family uses a 16-bit modified Harvard architecture with separate program and data buses, enabling single-cycle instruction fetch plus single-cycle data access. Within Microchip's portfolio the PIC24H bridges the PIC24F (low-power) and dsPIC33F (DSP) families, offering higher MIPS than PIC24F and lower cost than dsPIC33F. Key features of the PIC24HJ128GP506A-H/MR include a 12-bit ADC with up to 18 channels and 500 ksps conversion rate, two UART modules, two SPI modules, and two I2C modules. The 64-pin VQFN package exposes five 16-bit timer/counter modules, four input capture and four output compare/PWM channels, and a real-time clock-calendar with separate 32 kHz oscillator pins. The peripheral set is oriented toward closed-loop motor and power-conversion control where the 20 MIPS core can execute a single PID iteration every 50 ns. The architecture is built around a 16-bit register file and a hardware multiply unit that produces a 32-bit result in a single cycle, doubling effective DSP throughput compared with PIC24F devices. A 16-word deep shadow register bank enables fast interrupt response, and the on-chip 128 KB Flash supports self-programming under firmware control for in-field firmware updates - a critical feature for automotive ECU designs. Typical applications include BLDC/PMSM motor control, industrial sensor conditioning with on-chip ADC, automotive body and chassis modules, and consumer appliances. The AEC-Q100 grade allows direct deployment in cabin electronics and selected under-hood subsystems where ambient temperatures regularly cross 125 C.

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.

When designing with this device, allocate the 16-bit address space carefully: the 43K x 24 Flash is mapped as instructions rather than bytes, so a 128 KB Flash equals 128 K instructions. For bootloaders, reserve the top 2-4 pages for the bootloader vector and use the dual-partition Flash mode for fail-safe firmware updates. This page synthesizes distributor pricing, AEC-Q100 qualification status, drop-in same-package alternatives from the PIC24H and dsPIC33F families, and practical design notes not found in the manufacturer datasheet.

The Microchip Technology PIC24HJ128GP510A-H/PT is a 16-bit PIC microcontroller from the PIC24H family, delivering 20 MIPS of computational throughput with 128 KB of FLASH program memory (43K x 24) and 8 KB of RAM, housed in a 100-pin TQFP (PT) package rated for automotive (AEC-Q100) temperature grades. The device operates from a 3.0V to 3.6V supply and integrates peripherals including DMA, POR, PWM, and a Watchdog Timer with brown-out detect and reset. Background context: A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (typically FLASH), volatile data memory (RAM), and a rich peripheral set into one package. The PIC24H belongs to Microchip's 16-bit MCU category, which sits hierarchically between 8-bit PIC10/12/16/18 devices and 32-bit PIC32 devices. PIC24H MCUs use a modified Harvard architecture with a 16-bit data path and a 24-bit instruction word, optimized for high-speed repetitive computation and closed-loop control tasks such as motor drive, power conversion, and DSP-style signal conditioning. Key features of the PIC24HJ128GP510A-H/PT include its 16-bit core running at 20 MIPS, 128 KB self-programmable FLASH, 8 KB RAM, an 8-channel DMA controller, multiple PWM modules suitable for motor and power control, and a CAN 2.0B interface for automotive networking. The -H temperature grade extends the operating range from -40C to +150C, and the device is AEC-Q100 qualified for automotive electronics. The 100-pin TQFP package provides extensive I/O (up to 85 I/O pins), supporting numerous analog and digital peripheral assignments. Technically, the PIC24HJ128GP510A-H/PT uses a 16-bit modified-Harvard CPU with hardware multiply/divide and a 16x16-bit single-cycle MAC. It shares pin compatibility with the dsPIC33F family, enabling migration to DSP-enhanced variants without PCB rework. The 100-pin TQFP package measures 12 x 12 mm with a 0.5 mm pitch, providing sufficient pin count for full peripheral utilization including dual CAN, USB, and multiple UART/SPI/I2C interfaces. Typical applications include automotive body and chassis control, BLDC/PMSM motor drive, industrial automation controllers, sensor signal processing with the integrated 12-bit ADC, and CAN-connected distributed control nodes. The high MIPS count and DMA support make it suitable for real-time control loops where deterministic response is required. Designers should plan PCB layout for the 0.5 mm pitch TQFP, use the recommended MPLAB X IDE with XC16 compiler, and consider the AEC-Q100 -H grade for under-hood or harsh-environment automotive use. Migration paths to the lower-temperature -I grade or to the dsPIC33F DSP family are straightforward due to pin compatibility.

PIC24HJ128GP510A-I/PT

PIC24HJ128GP510A-I/PT - 16-bit 40 MIPS 128KB Flash MCU | Microchip

The Microchip Technology PIC24HJ128GP510A-I/PT is a high-performance 16-bit microcontroller from the PIC24H family, delivering 40 MIPS of CPU throughput from a 16-bit modified Harvard architecture in a 100-pin TQFP package. It integrates 128 KB of Flash program memory (43K x 24 words), 8 KB of SRAM data memory, and 85 general-purpose I/O lines, and is positioned for high-speed repetitive computation and closed-loop digital control. Background: A microcontroller (MCU) is a single-chip computer that combines a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and a rich set of peripherals on one die. The PIC24H sits inside Microchip's 16-bit MCU portfolio, which itself is part of the broader microcontroller -> embedded processor -> semiconductor product hierarchy. The 'J' suffix indicates the dsPIC33F-compatible enhanced core, and the family is pin-compatible with the dsPIC33F signal-controller line, simplifying migration between pure control and DSP-augmented designs. Key features include a 16-bit data path, single-cycle 16x16 MAC hardware, hardware DMA controller with 8 channels, two UART modules, two SPI modules, two I2C modules, two CAN modules, an ECAN module, a Parallel Master Port (PMP), a 10-bit A/D converter with up to 32 input channels and 500 ksps conversion rate, a 16-bit timer/counter, and a JTAG boundary-scan interface for in-system debug. The 100-pin TQFP (12x12 mm) package provides ample I/O for parallel-bus and mixed-signal designs. Architecturally, the PIC24HJ128GP510A uses a 40 MHz internal oscillator with a 4-phase PLL and shadow register sets for fast interrupt response. The DMA engine offloads data movement between peripherals and memory, freeing the core for control algorithms. The 10-bit ADC integrates sample-and-hold and multiple trigger sources, enabling synchronized multi-channel sampling without CPU intervention. Typical applications include industrial motor control (BLDC, PMSM, AC induction), digital power conversion (SMPS, PFC), automotive body and chassis ECUs, medical instrumentation, high-performance sensor-fusion nodes, and CAN-connected industrial automation. The combination of CAN, ECAN, UART and JTAG makes it especially attractive for networked embedded systems. When designing with this device, reserve a 4-pin header for the ICD 3 debugger/programmer and decouple every VDD/AVDD pin with a 100 nF X7R ceramic placed within 5 mm. For ADC accuracy, isolate AVSS from digital ground with a single-point connection or ferrite bead; the 10-bit ADC requires careful analog-layout practice.

PIC24HJ128GP510AT-I/PF

PIC24HJ128GP510AT-I/PF - 16-bit 40MIPS 128KB Flash MCU | TQFP-100

The Microchip Technology PIC24HJ128GP510AT-I/PF is a 16-bit microcontroller from the PIC24H family that delivers 40 MIPS performance at 3.3V, integrating 128 KB program Flash and 8 KB SRAM in a 100-pin TQFP (14x14 mm) package with 85 general-purpose I/O pins. The device is part of the PIC24HJ128GP510A silicon revision (A denotes the second die revision with peripheral improvements), and the 'T' suffix indicates tape-and-reel packaging, while 'I/PF' specifies the -40°C to +85°C industrial temperature range and the 100-pin TQFP package. A 16-bit microcontroller (MCU) is a single-chip computer that combines a CPU, non-volatile Flash program memory, volatile SRAM, and configurable peripherals such as timers, ADC modules, communication interfaces, and GPIO. 16-bit MCUs occupy the performance tier between 8-bit parts (PIC16, 8051) and 32-bit Cortex-M parts, and the PIC24H family specifically targets high-speed digital-signal-control and motor-control applications. The PIC24HJ128GP510AT-I/PF belongs to the broader category of microcontrollers > digital signal controllers > integrated circuits. Key features of the PIC24HJ128GP510AT-I/PF include up to 40 MIPS operation from a 3.0 V to 3.6 V supply, 128 KB (43K x 24 instruction words) self-programmable Flash, 8 KB SRAM, two 3-wire SPI modules, two I2C modules, two UART modules, two CAN modules, two 16-channel 10/12-bit ADC modules, and a hardware multiplier for DSP-class operations. The 85 GPIO pins tolerate 5V input on most pins, simplifying mixed-voltage designs with legacy 5V peripherals. Architecture-wise the PIC24HJ128GP510A revision uses a modified Harvard architecture with separate 24-bit program and 16-bit data paths, a 16 x 16-bit single-cycle hardware multiplier, and a 40-bit barrel shifter. This gives the device enough headroom for PID loops, motor-control algorithms, and basic DSP filters while remaining fully programmable in plain C through Microchip's MPLAB XC16 toolchain. The 100-pin TQFP package also enables pin-compatibility with the dsPIC33F family for migration paths to DSP-extended parts. Typical applications include industrial motor control (BLDC, PMSM, stepper), sensor interfaces, factory automation, LED lighting controllers, uninterruptible power supplies (UPS), and CAN-bus node endpoints. Industrial control boards particularly value the device's two CAN 2.0B modules plus 5V-tolerant GPIOs for interfacing to legacy industrial buses. When designing with this MCU, reserve at least 2 pF of decoupling per VDD/AVDD pin and follow Microchip's recommended 16 MHz external crystal or 7.37 MHz internal FRC + PLL configuration to hit the maximum 40 MIPS throughput. The 'I' (industrial) grade variant is the correct choice for non-automotive deployments; for AEC-Q100-qualified automotive applications, switch to the corresponding 'F' (automotive) grade device.

The device integrates a 16-channel 10/12-bit ADC, multiple UART/SPI/I2C peripherals, DMA, and motor control PWMs, while operating from a 3.0 V to 3.6 V supply. A 16-bit microcontroller (MCU) is a microprocessor that processes data 16 bits at a time, sitting between 8-bit MCUs (lower cost, simpler control) and 32-bit MCUs (higher throughput, more complex OS). The PIC24H architecture uses a modified Harvard RISC core with deterministic interrupt latency and a single-cycle hardware multiplier/DSP engine, positioning it between the 8-bit PIC18 family and the 32-bit PIC32/PIC32MM families in Microchip's portfolio. Key features include 128 KB Flash, 8 KB RAM, 53 digital I/O pins, four 16-bit timers, two UART/SPI/I2C ports, ECAN, a 16-channel 12-bit ADC with 500 ksps throughput, and a parallel master port (PMP). The industrial-grade -40C to +85C operating range suits process control and motor drive applications. The wide peripheral set replaces glue logic and external ADCs in many designs. The PIC24HJ128GP510A die uses 0.25-micron CMOS with on-chip voltage scaling and a phase-locked loop (PLL) to derive 40 MIPS from a 10 MHz crystal, while a redundant watchdog timer and dual brown-out reset improve field reliability. The instruction set is fully compatible with the dsPIC33F DSC family, so firmware is portable between control-only and DSP+control designs. Typical applications include industrial motor control (BLDC, PMSM, stepper), power conversion (digital PFC, solar micro-inverter), factory automation PLCs, automotive sensor interfaces, and medical instrumentation. The combination of CAN/ECAN, motor-control PWMs and a 12-bit ADC makes it well suited for closed-loop motor and power-electronic control. When designing with this device, allocate a 4-byte configuration word in Flash, decouple the analog and digital VDD rails separately, and follow Microchip's emulator header layout for MPLAB REAL ICE/ICD debugging. Use the DMA controller for ADC-to-memory transfers to free the CPU for control loops.
