PIC24FJ128GC006T-I/PT - 16-Bit 32MHz 128KB Flash MCU | Microchip

The Microchip Technology PIC24FJ128GC006T-I/PT is a 16-bit PIC® XLP™ 24F microcontroller running at 32 MHz, delivering 128 KB of Flash program memory and 8 KB of SRAM, in a 64-pin TQFP (10x10 mm) package. It is part of the PIC24FJ128GC006 family of "Intelligent Analog" parts, integrating a 16-bit Sigma-Delta ADC, a 12-bit 10 MSPS pipeline ADC, dual 10-bit 1 MSPS DACs, and two on-chip operational amplifiers for precision signal conditioning. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one die. The PIC24F family uses a 16-bit modified Harvard architecture with a wide 24-bit instruction word, sitting above 8-bit PIC MCUs and below 32-bit ARM Cortex-M devices in performance, cost, and power hierarchy. The "XLP" (eXtreme Low Power) designation means this part targets battery-backed and energy-harvesting designs, complementing standard PIC24F parts. Key differentiating features include a USB On-The-Go (OTG) full-speed peripheral for direct device/host connectivity without an external bridge, a segmented LCD driver supporting glass up to several hundred segments, and the dual-ADC architecture that lets the same MCU digitize both high-bandwidth signals (12-bit pipeline at 10 MSPS across 30 channels) and high-resolution low-frequency signals (16-bit Sigma-Delta) for weigh-scale, temperature, or strain-gauge front ends. The 2x on-chip op-amps further reduce external analog count. Architecturally, the part leverages Microchip's standard PIC24F core with hardware multiplier, single-cycle MAC, and a 16-bit-wide datapath. Integrated Intelligent Analog reduces BOM by absorbing signal-chain functions that would otherwise need dedicated analog ICs, while 32 MHz operation gives ~16 MIPS throughput for signal processing and USB protocol stacks. Typical applications include portable medical instrumentation (glucose meters, pulse oximeters), industrial sensor transmitters, USB-connected data loggers, and battery-powered metering. The wide analog integration makes it especially suitable where board space, BOM cost, and low quiescent current matter more than raw CPU horsepower. When designing with this MCU, budget the I/O count against the 64-pin TQFP carefully - several pins are multiplexed with analog and LCD functions. Plan the PCB layout so the analog grounds are isolated from digital switching currents, especially with USB present.

The 121-TFBGA package enables high-density designs with 100+ I/O. Architecture is a modified Harvard 16-bit RISC core with 16-bit wide instructions, dual-cycle hardware multiply, single-cycle bit manipulation, and zero-cost shadow register banks. The dual-ADC system (pipeline + Sigma-Delta) and integrated LCD driver eliminate external analog ICs, reducing BOM and PCB area. Typical applications include portable medical devices (glucose meters, pulse oximeters), industrial data loggers, USB peripherals, battery-powered sensor hubs, e-metering, low-power HMI with LCD, and touch-sense user interfaces. The integrated Sigma-Delta ADC particularly suits weigh scales, temperature bridges, and precision instrumentation. When designing with this MCU, leverage PPS for flexible signal routing, use the internal charge pump to drive LCD at low VDD, and exploit Sleep modes with peripheral wake to maximize battery life. The TFBGA package requires careful PCB design - microvia stack-up and 0.5 mm pitch traces are recommended.

It belongs to the PIC24FJ 'GL' family, which targets battery-powered human-machine interface (HMI) applications that demand long runtimes and on-glass animation. A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (Flash), working RAM, and a rich set of peripherals such as timers, ADCs, communication interfaces, and increasingly domain-specific blocks like LCD drivers. The PIC24FJ 'GL' family layers core-independent peripherals (CIPs) on top of a 16-bit modified Harvard architecture that runs the MIPS instruction set, providing deterministic interrupt response and low power draw. The PIC24FJ128GL302 sits within the low-pin-count subset of this family, fitting 28-pin designs while still integrating the segmented LCD controller. Key differentiating specifications include: sleep current down to a few hundred nanoamps with full RAM retention, segmented LCD controller supporting up to 256 segments (8 common, 32 segment lines) with an integrated charge pump for contrast in battery-powered applications, core-independent autonomous display animation (alternating dual display, blinking, blanking), 128KB Flash with ECC for safety-critical code, and AEC-Q100 qualification for automotive dashboard and instrument-cluster designs. Technically, the device combines a 16-bit MIPS core with a 4-channel DMA engine, multiple I/O ports with interrupt-on-change capability, and an RTCC with calendar mode. The integrated charge pump lets the LCD run from a low-voltage battery while producing VGH/VGL rails suitable for contrast, eliminating an external boost circuit. Hardware crypto and a true RNG are not part of this part; they are found on PIC24F 'GB' family devices. Typical applications include battery-powered thermostats, remote controls, white-goods HMIs, e-bike or e-scooter dashboards, blood-pressure monitors, and automotive instrument clusters where low quiescent current and a built-in LCD driver reduce bill of materials. In an HMI design it drives the glass directly while the CPU sleeps, waking only on a button interrupt, then returns to sub-microamp standby. Design consideration: When migrating from a PIC24F 'KA' or 'KL' part, verify the pin mapping in the 28-pin QFN variant - the GL family reassigns several I/O pins to LCD segment lines. Always populate the VLCD charge-pump flying capacitor per the datasheet typical-application schematic.

The PIC24FJ128GL302's CIP architecture - comprising the LCD controller, charge pump, configurable logic cells, and the math-to-life feature - lets the chip sustain an animated LCD interface while the CPU stays in deep sleep. The MIPs-to-power ratio of 16 MIPS from a sub-mA active budget, combined with hardware ECC on Flash, targets battery-powered human-machine interfaces such as utility meters, e-meter displays, and medical dosing devices that must run for years on a single cell. Typical applications include battery-powered metering with LCD readout, low-power IoT sensor nodes with local HMI, medical dosing pumps with LCD indicators, electronic shelf labels, consumer appliances with segment displays, and portable industrial gauges. The autonomous LCD animation is particularly valuable in any system that must keep an animated user interface alive while consuming negligible quiescent current. When designing with this MCU, ensure decoupling is placed close to VDD/AVDD/VBAT pins and that the LCD charge pump output is routed away from analog sense traces. Developers should leverage MPLAB X IDE and the MPLAB Code Configurator (MCC) for peripheral setup, and review the 'Low Power Modes' chapter of the datasheet to align CPU idle time, LCD duty, and CIP activity with the application's battery-life target.

It runs at up to 32MHz (16 MIPS) on the 16-bit PIC24 CPU core and is housed in a 36-pin UQFN (5x5 mm) package. The "T" suffix denotes Tape and Reel packaging, and the "I" suffix denotes the industrial -40C to +85C operating temperature range. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals including timers, communication interfaces, and analog blocks. The PIC24FJ "GL" sub-family extends Microchip's eXtreme Low Power lineage with Core Independent Peripherals (CIPs) and dedicated segmented LCD driver logic, eliminating the CPU from animation and contrast-management tasks so the device can remain in deep sleep for years on a single battery cell. Key features include a charge pump for contrast management across VDD down to battery-low conditions, an asynchronous segmented LCD controller capable of alternating dual display, blinking and blanking animations without CPU intervention, deep sleep current measured in hundreds of nA with full RAM retention, 5V-tolerant I/O on most pins, and a JTAG/ICD debugging interface. The 36-pin UQFN footprint provides a compact 5x5 mm PCB area suitable for handheld and wearable product designs. Architecturally, the PIC24FJ GL family uses a 16-bit modified Harvard architecture with a 24-bit instruction word, providing deterministic interrupt latency and a CIP ecosystem that includes configurable logic cells, multiple PWM/SCCP/MCCP timers, 12-bit ADC, comparators, and the RTCC with calendar mode. The integrated LCD charge pump operates from a single supply, supporting low-battery operation without external boost components. Typical applications include battery-powered thermostats, portable medical monitors (glucometers, pulse oximeters), utility metering end-points with LCD readouts, e-bike and fitness wearables, white-goods user interfaces, and any product that requires a segmented LCD with multi-year battery life. The automotive-grade variant (AEC-Q100 qualified) addresses dashboard and instrument-cluster designs. When designing with this part, plan the PCB layout to keep the LCD segment traces short and isolated from switching nodes, since segment lines can act as antennas into the analog domain. The charge pump capacitor should be placed as close as possible to the VLCAP pins, and the external 32.768 kHz crystal footprint (SOSC) is required if the RTCC is used for timekeeping. This page synthesizes distributor pricing tiers, drop-in alternatives, application circuits, and PCB layout notes that are not consolidated in any single distributor or manufacturer resource, helping engineers evaluate the PIC24FJ128GL303T-I/M5 quickly for both new designs and supply-chain sourcing decisions.

The hardware charge pump generates the LCD bias voltages internally, eliminating the external resistor ladder and enabling stable contrast even as the battery voltage drops below the Vlcd threshold. Extended temperature support makes it suitable for outdoor, industrial, and automotive interior applications. Architecturally, the device uses a 16-bit modified Harvard core with separate instruction and data paths, hardware multiplier, and zero-overhead loop control. The CIPs (CLC, MCCP, UART with IrDA, timers, and PWM) operate independently of the core, allowing complex waveform generation, signal conditioning, and communication events to occur while the CPU remains asleep. The combination of hardware encryption, true RNG, and secure boot options provides a foundation for connected low-power nodes. Typical applications include battery-powered medical devices such as glucose meters and infusion pumps, IoT sensor nodes with on-board segmented LCD displays, HVAC thermostat controllers, industrial metering (gas, water, electricity) with multi-segment displays, e-bike and appliance user interfaces, and portable consumer products requiring years of battery life. The extended -40C to +125C temperature range also makes it attractive for outdoor signage and asset tracking tags. When designing with this MCU, choose decoupling capacitors and follow Microchip's recommended PCB layout for the LCD charge pump; improper layout can introduce display flicker.

PIC24F devices sit in Microchip's mid-range 16-bit MCU tier: 16-bit wide data path, modified Harvard architecture, deterministic interrupt latency, and excellent code density compared with 8-bit MCUs. Within that family, the 'GL4' sub-family is engineered for ultra-low-power and human-machine-interface (HMI) applications, providing extended sleep current as low as hundreds of nanoamperes with multiple low-power modes that preserve RAM and peripheral state. Key features of this variant include 128 KB dual-partition Flash supporting real-time OTA updates and EEPROM Emulation (EER), 32 KB SRAM, 16 MIPS sustained throughput at 32 MHz, integrated full-speed USB 2.0 device/host/OTG controller, an integrated segmented LCD driver supporting hundreds of pixels, up to 38 I/O pins with mappable peripherals via PPS (Peripheral Pin Select), and CIP blocks including a 12-bit ADC, multiple UART/SPI/I²C interfaces, comparators, and configurable logic cells. Typical applications for the PIC24FJ128GL405-I/M4 include battery-powered IoT sensor nodes with segment-LCD displays, USB-CDC tethered data loggers, portable medical monitors, industrial HMI panels, home automation gateways, and metering/utility front-ends. The device also targets firmware-upgradable field installations that require secure dual-bank OTA updates. When designing with this MCU, plan the I/O map early because PPS allows nearly every digital peripheral to be routed to most pins, simplifying PCB layout. Place a 0.1 µF ceramic decoupling capacitor within 5 mm of every VDD/VSS pair, route the 32 kHz crystal traces symmetrically to the SOSC pins, and allocate one PGECx/PGEDx pair for the ICSP interface so firmware can be debugged and updated in-circuit.

PIC24FJ128GL405-I/PT - 16-bit MCU, 128KB Flash, LCD, USB | Microchip

The Microchip Technology PIC24FJ128GL405-I/PT is a 16-bit eXtreme Low-Power microcontroller from the PIC24FJ GL4 family, featuring 128 KB of ECC Flash, 32 KB RAM, an integrated segmented LCD controller, and a full-speed USB 2.0 peripheral, housed in a 48-pin TQFP (7x7 mm) package. It executes instructions at up to 16 MIPS from a 32 MHz internal oscillator and operates from 2.0 V to 3.6 V across an industrial temperature range of -40 C to +85 C. The 'GL4' family integrates Core Independent Peripherals (CIPs), configurable logic cells, and a 32 KB dual-partition Flash with EEPROM emulation, supporting real-time Over-The-Air (OTA) firmware updates without device downtime. A 16-bit PIC microcontroller is a Harvard-architecture MCU that processes instructions on a 16-bit data path while fetching code over a separate 24-bit bus, giving a single instruction a higher arithmetic density than 8-bit cores. It belongs to the wider category of embedded microcontrollers, which sits between general-purpose microprocessors and application-specific DSPs in the embedded computing hierarchy. The PIC24FJ family extends the original PIC16/PIC18 architectures with enhanced peripherals, larger linear address space, and significantly higher code efficiency for C-based firmware development, while preserving the deterministic interrupt latency Microchip MCUs are known for. Differentiating features of the PIC24FJ128GL405 include 128 KB of ECC-protected program memory, 32 KB SRAM, an integrated segmented LCD driver supporting up to 288 segments, and a full-speed USB 2.0 device peripheral with internal transceiver. Core Independent Peripherals such as CLC, MCCP, and configurable 16-bit timers enable complex event handling without CPU intervention, dramatically reducing active-mode current. The dual-partition Flash with EEPROM emulation allows reliable OTA field upgrades and parameter storage without external memory, while hardware AES and a true random number generator provide security primitives for connected applications. Typical applications include battery-operated medical devices, industrial HMI panels with LCD readouts, USB-connected sensor nodes, smart metering and energy-harvesting products, IoT edge nodes, and human-machine interface controls in appliances. The wide operating voltage, deep sleep current in the microamp range, and segmented LCD controller reduce system BOM by eliminating external driver ICs and boost regulators in many designs. When designing with the PIC24FJ128GL405-I/PT, place decoupling capacitors within 3 mm of every VDD/VSS pair and keep the USB D+/D- traces length-matched and 90-ohm impedance-controlled to pass USB compliance. Configure the dual-partition Flash map before firmware deployment so OTA updates can swap partitions safely, and leave the WDT enabled during sleep for unattended recovery.

PIC24FJ128GL405T-I/PT - 16-Bit MCU, 128KB Flash, LCD, USB | Microchip

The Microchip Technology PIC24FJ128GL405T-I/PT is a 16-bit PIC24F microcontroller running at 32 MHz (16 MIPS) with 128 KB ECC Flash and 32 KB SRAM, housed in a 48-pin TQFP (7x7 mm) package. The GL4-family silicon integrates a segment LCD controller, full-speed USB 2.0 (device/host/OTG), and core-independent peripherals (CIPs) that offload tasks from the CPU. What is a PIC24F microcontroller? The PIC24F is Microchip's 16-bit MCU family, sitting between 8-bit PIC16/PIC18 and 32-bit PIC32. It uses a modified Harvard architecture with a 16-bit wide datapath, providing roughly an order-of-magnitude more throughput than 8-bit PIC MCUs while retaining the deterministic interrupt model and peripheral set familiar to PIC developers. The F-prefix denotes the ultra-low-power eXtreme Low Power (XLP) sub-family, targeted at battery-powered and energy-harvesting designs. Microcontroller -> MCU -> embedded controller -> semiconductor. PIC24FJ -> PIC24F -> 16-bit MCU -> embedded controller. Key features include dual-partition Flash (live Over-The-Air updates plus EEPROM emulation), up to 39 general-purpose I/O, hardware Crypto engine (AES/SHA), 16-bit Sigma-Delta ADC and 10-bit pipelined ADC, multiple PWM/SCCP/MCCP timers, Real-Time Clock and Calendar (RTCC) with backup battery domain, and a USB Peripheral Annex down to 2V. The segment LCD driver supports up to 320 segments, making the part suitable for human-machine interface panels. Architecture-wise, the device pairs a 16-bit MIPS-style core with five core-independent peripherals (configurable logic cells, NCO, CLC, ADC shutdown, hardware crypto) that continue executing state machines without CPU intervention. Dual-partition Flash enables A/B firmware switching for fail-safe field updates, and ECC Flash plus parity-protected SRAM raise reliability in long-life industrial deployments. Typical applications include industrial HMI panels with segment LCD and USB diagnostics, IoT sensor nodes with OTG firmware updates, battery-backed metering and e-metering, white-goods user interfaces, medical point-of-care displays, and automotive body/chassis auxiliary modules. The 32 KB RAM supports modest protocol stacks (USB CDC, Modbus, MQTT-SN) without external memory. When designing with this part, select the correct voltage regulator topology for the 2V-3.6V VDD range and budget for the LCD charge-pump capacitor network. The dual-partition Flash must be managed via Microchip's bootloader library for OTA updates to work reliably.
