PIC24FV32KA301-E/P - 32KB Flash 16-bit XLP MCU | Microchip

The Microchip PIC24FV32KA301-E/P is a 16-bit PIC microcontroller from the PIC24F XLP (eXtreme Low Power) family, featuring 32KB of Flash program memory, 2KB of RAM, and 512 bytes of EEPROM, housed in a 20-pin PDIP (0.300 inch, 7.62mm) through-hole package. It operates at up to 32MHz (16 MIPS) and is rated for the extended industrial temperature range (-40C to +125C) as denoted by the -E suffix, making it suitable for harsh-environment designs. A PIC microcontroller is a compact programmable processor that integrates a CPU, non-volatile program memory, RAM, and I/O onto a single silicon die. The PIC24F series uses a 16-bit modified Harvard architecture with a rich peripheral set, sitting between 8-bit PIC MCUs and 32-bit offerings in Microchip's portfolio. Within the PIC24F family, the XLP variants add specialised low-power peripherals such as Deep Sleep Brown-Out Reset (DSBOR), Deep Sleep Watchdog Timer (DSWDT), and a Real-Time Clock and Calendar (RTCC) that continue to operate in Deep Sleep mode, enabling years of battery life on a single cell. Key features of the PIC24FV32KA301-E/P include a 12-bit ADC with up to 16 channels, a Charge Time Measurement Unit (CTMU) for capacitive touch and precise time measurement, multiple serial interfaces (UART, SPI, I2C), and 17 general-purpose I/O pins. The device supports 5V operation (the FV designation), allowing direct interface with 5V logic and easing migration from legacy 8-bit designs. The internal oscillator reduces BOM cost and PCB area, while the wide operating range (2.0V-5.5V) supports battery-powered and energy-harvesting applications. Technically, the PIC24FV32KA301-E/P uses a 16-bit RISC core with single-cycle execution (except for program branches), hardware stack, and a flexible interrupt controller with up to five interrupt sources. The CTMU provides a constant current source for capacitive touch sensing or precise time measurement, useful in human-interface designs. Deep Sleep current can drop below 1 uA with RTCC active, an industry-leading figure for this class of MCU. Typical applications include battery-powered sensors, portable medical devices, remote controls, IoT edge nodes, capacitive touch user interfaces, and industrial control nodes. Designers choose this part when they need the combination of 5V-tolerant I/O, low deep-sleep current, and a generous memory complement in a familiar through-hole package that simplifies prototyping and hand-rework. When designing with this part, prefer the internal RC oscillator with PLL for most applications to minimise external components, and reserve the RTCC for timekeeping during sleep. Use the CTMU for touch sensing and avoid high-source-impedance signals on ADC inputs to preserve conversion accuracy.

Operating at up to 32 MIPS with a 32MHz CPU clock, it is designed for power-constrained and battery-powered applications across industrial and consumer markets. The device operates from 2.0V to 5.5V and includes a 12-bit ADC, CTMU (Charge Time Measurement Unit), RTCC, and 17 general-purpose I/O. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, peripherals, and I/O onto one die. Microcontrollers serve as the embedded intelligence in everything from thermostats to industrial controllers; the 16-bit PIC24F family specifically targets low-power applications where 8-bit MCUs are too slow but Cortex-M parts are too power-hungry. Within the broader taxonomy, the PIC24F sits between PIC16/PIC18 8-bit parts and dsPIC33/PIC32MX 32-bit parts, offering 16-bit performance at 8-bit-style energy budgets. Key differentiating features of the PIC24FV32KA301 include industry-leading XLP sleep currents as low as 20nA (Deep Sleep with RTCC), the CTMU peripheral for capacitive touch sensing, the Peripheral Pin Select (PPS) remappable I/O for flexible PCB routing, and a 5V-tolerant I/O structure that simplifies interface to legacy 5V peripherals. The -E suffix denotes an extended temperature grade (-40C to +125C) and the /SO suffix denotes the 20-pin SOIC package with 300-mil body width. Architecturally, the PIC24FV32KA301 uses a modified Harvard architecture with separate program and data buses, a hardware multiply/divide unit, and a 16-element working register array. The integrated nanoWatt XLP technology combines multiple power-saving modes (Sleep, Deep Sleep, Deep Sleep with RTCC, and Retention) to minimize active and standby energy. CTMU provides a constant-current source for time-based measurement of capacitance changes, enabling touch buttons, sliders, and fuel gauging without external components. Typical applications include battery-powered IoT sensors, wearable medical devices, remote controls, low-energy wireless sensor platforms (with companion RF ICs), energy harvesting endpoints, and capacitive touch human-machine interfaces. The 5V tolerance and industrial temperature range suit it to factory automation and white goods, while the small SOIC-20 footprint supports compact handheld products. In low-duty-cycle applications where the wake-and-sleep duty ratio is low, the nA-level deep sleep current often matters more than active MIPS, and the XLP feature set is decisive. When designing with this part, pay close attention to the 47k pull-up on MCLR (per Microchip programming specification) and the configuration bit requirements for low-voltage programming. Boundary-scan JTAG is not supported on this family; use ICSP via PGC/PGD instead. Decouple VDD with at least 0.1uF + 10uF bulk per rail, and route analog reference (AVDD/VREF+) separately from digital VDD if ADC accuracy matters.

The architecture balances deterministic interrupt latency with high-throughput DSP-style computation, making the line a transitional point between classic 8-bit PIC MCUs and full dsPIC digital signal controllers. Key features of the PIC24HJ128GP202 include 16-channel 10/12-bit ADC with 500 ksps conversion, two UART, two SPI, one I2C, up to 21 general-purpose I/O pins, a 16-bit timer/capture/compare/PWM block, and a direct memory access (DMA) controller with 8 channels. The device operates from 2.0 V to 3.6 V and includes an on-chip 8 MHz internal oscillator with PLL to generate the 40 MIPS instruction rate, plus JTAG and ICSP in-circuit debugging interfaces. The PIC24HJ128GP202 architecture uses a single-cycle 16-bit ALU and hardware multiply/divide to deliver deterministic control loop performance. The DMA engine moves data between peripherals and memory without CPU intervention, freeing the core for application-level computation; combined with 128 KB Flash and 8 KB SRAM this enables moderate data-acquisition and motor-control workloads on-chip. Typical applications include industrial motor control (BLDC, stepper, switched reluctance), digital power conversion (SMPS PFC and phase-shifted full-bridge), sensor signal conditioning, UPS and inverter controllers, and automotive body/comfort ECUs where the -E temperature grade is mandatory. The pin compatibility with the dsPIC33F family allows code migration when DSP extensions are later required. When designing with this part, allocate the analog and digital supply pins (AVDD/AVSS) decoupling to a clean analog ground plane to preserve ADC accuracy, and consult Microchip's TB3138 application note for high-performance ADC layout guidelines. The extended temperature range and 128 KB Flash position this MCU for safety-margin industrial designs, while the SOIC-28 footprint simplifies hand prototyping and rework versus QFN packages. This page synthesizes distributor pricing, pin-compatible drop-in alternatives across the PIC24H family, and practical design notes that go beyond the manufacturer datasheet summary, giving engineers a single source for evaluation and procurement.

PIC24HJ128GP202-I/SO

PIC24HJ128GP202-I/SO - 16-bit 40MIPS 128KB Flash MCU | Microchip

The Microchip PIC24HJ128GP202-I/SO is a 16-bit microcontroller from the PIC24H family, featuring a 40 MIPS CPU with 128 KB Flash and 8 KB SRAM, housed in a 28-pin SOIC wide-body package. It integrates a 16-channel 10-bit/12-bit ADC, multiple UART/SPI/I2C peripherals, and DMA into a single chip designed for high-speed control and signal-processing tasks. A 16-bit microcontroller (MCU) is a programmable embedded processor that fetches and executes 16-bit wide instructions, providing significantly more arithmetic throughput than 8-bit MCUs while preserving deterministic, low-latency interrupt behavior. Within the embedded hierarchy, MCUs sit below microprocessors and above digital signal processors in complexity; the PIC24H family specifically targets applications that demand both fast control loops and DSP-style computation. Because the PIC24HJ128GP202 is pin-compatible with the dsPIC33F family, designers can upgrade to a full DSP engine without board rework. Key features of the PIC24HJ128GP202 include a 16-bit modified Harvard core with hardware multiply/divide, 128 KB self-programmable Flash with ECC, 8 KB SRAM, a 16-channel 12-bit ADC capable of 500 ksps, two UART modules, two SPI ports, two I2C ports, eight PWM outputs, a 16-bit timer/counter bank, and a peripheral pin-select (PPS) remap feature that allows digital peripherals to be assigned to alternate I/O pins. The device also includes a real-time clock and calendar (RTCC), five 16-bit timer/counters, and a 9-channel DMA controller that offloads memory-to-peripheral transfers from the CPU. Architecturally, the PIC24HJ128GP202 combines a 16-bit datapath with a 24-bit instruction word, enabling single-cycle multiply and divide operations. Its DMA engine and dual-port SRAM eliminate many CPU stalls in high-throughput sensor and motor-control loops, while the PPS remap system decouples peripheral selection from PCB layout, allowing rapid port re-use when design constraints change. The wide operating voltage range (3.0V-3.6V) and -40C to +85C industrial temperature range make the device robust against supply and thermal variation in factory-floor environments. Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion (AC/DC, DC/DC, PFC), multi-loop PID process controllers, sensor-fusion front-ends, and advanced sensor interfaces such as MEMS accelerometers and gyroscopes. The combination of DSP-class arithmetic, DMA, and 12-bit ADC sampling at 500 ksps enables designers to consolidate what previously required an external DSP into a single 28-pin MCU. When designing with this part, plan the PPS remap configuration early to avoid I/O conflicts between digital peripherals. For motor-control firmware, reserve at least one DMA channel for ADC-to-PWM timing to keep current-loop latency deterministic.

PIC24HJ128GP202T-I/MM

PIC24HJ128GP202T-I/MM - 40 MIPS 16-bit MCU, 128KB Flash | Microchip

The Microchip Technology PIC24HJ128GP202T-I/MM is a 16-bit microcontroller from the PIC24H family, delivering 40 MIPS performance at 3.3V from a modified Harvard RISC architecture. It integrates 128 KB (43K x 24 words) of Flash program memory and 8 KB of RAM in a 28-pin QFN-S (6x6 mm) package with exposed thermal pad, supplied on tape and reel (the T suffix). What is a PIC24H 16-bit microcontroller? The PIC24H is a high-performance 16-bit MCU family from Microchip Technology that occupies the mid-range position between the 8-bit PIC18 and the 32-bit PIC32MX. Architecturally, a PIC24H combines a 16-bit data path with a 24-bit instruction word, giving it code density comparable to 32-bit cores while keeping interrupt latency predictable for hard real-time control loops. The PIC24H family is also pin-compatible with the dsPIC33F DSC family, so a designer can migrate to DSP extensions by simply swapping the chip. Key features of the PIC24HJ128GP202T-I/MM include the 40 MIPS core, an integrated 12-bit A/D converter with up to 10 channels, multiple communication peripherals (UART, SPI, I2C), and a 16-bit timer/capture/compare module. The -I suffix indicates the industrial temperature grade of -40C to +85C. The QFN-S 28 package is the smallest 28-pin option in this family and exposes a thermal pad for improved heat spreading in space-constrained layouts. Technically, the device operates from a single 3.0-3.6V supply and supports up to 16 MIPS at 3.0V, scaling to 40 MIPS at 3.3V. It includes a JTAG programming/debug interface and uses Microchip's ICSP (In-Circuit Serial Programming) for in-field firmware updates. The combination of high throughput, large memory and rich analog/digital peripherals makes it suitable for closed-loop control, motor drive front ends, and sensor processing. Typical applications include motor control (BLDC and PMSM), industrial automation and sensor hubs, advanced sensing front ends, switched-mode power supply control, and embedded data acquisition. The wide peripheral mix and 5V-tolerant digital inputs make it a strong fit for mixed-signal industrial boards. When designing with this part, plan the PCB layout so that the exposed pad on the QFN package is soldered to a copper pour. Do not exceed 3.6V on VDD; although the digital inputs are 5V-tolerant, the supply must remain within the 3.0-3.6V window for the analog blocks to meet datasheet performance. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes beyond what is found in the manufacturer datasheet alone, giving procurement and design engineers a single reference for the PIC24HJ128GP202T-I/MM.
