PIC24FJ64GA110-I/PF

PIC24FJ64GA110-I/PF - 16-bit MCU, 64KB Flash, 100-TQFP | Microchip

The Microchip Technology PIC24FJ64GA110-I/PF is a 16-bit RISC Flash microcontroller from the PIC24F family, delivering 16 MIPS at 32 MHz with 64 KB of program Flash and 16 KB of on-chip data RAM, housed in a 100-pin TQFP (14x14 mm) package. It belongs to the PIC24FJ64GA110 series which targets low-power (<100 nA standby current) and connectivity-rich general-purpose embedded applications, integrating 3x I2C, 3x SPI, 4x UART, and 23 independent timers alongside a 10-bit ADC and parallel master port. Background knowledge - what is a PIC24F microcontroller? The PIC24F is a 16-bit modified-Harvard RISC microcontroller family from Microchip Technology, sitting between the 8-bit PIC16/PIC18 families and the 16-bit dsPIC families in the Microchip portfolio. PIC24F devices use a 16-bit instruction word with 24-bit instruction encoding, deliver up to 16 MIPS performance, and are recognized for eXtreme Low Power (XLP) technology with nanoWatt sleep currents. They target the same role in the system hierarchy as Cortex-M0/M0+ parts from other vendors: low-power, cost-sensitive, connectivity-rich embedded control where an 8-bit core is too constrained but a full Cortex-M3/M4 is overkill. Key features include 64 KB (22K x 24) self-programmable Flash, 16 KB SRAM, a hardware Real-Time Clock and Calendar (RTCC) with calendar mode, a 16-channel 10-bit ADC with 500 ksps conversion rate, and the Peripheral Pin Select (PPS) remapping system that allows flexible assignment of digital peripherals to I/O pins. The device supports 2.0V to 3.6V single-supply operation and offers four power-managed modes: Run, Idle, Sleep with RTCC, and Deep Sleep. The PIC24FJ64GA110 uses a modified-Harvard architecture with separate 24-bit program and 16-bit data paths, hardware multiply/divide, and a 16-element working register array. The PPS subsystem maps digital peripheral functions (UART, SPI, I2C, timer outputs, interrupt inputs) onto selected RPn pins via configuration bits, simplifying PCB routing. The integrated RTCC with timestamp and tamper-detection features is uncommon in this class and reduces external RTC component count. Typical applications include low-power IoT sensor nodes, industrial HMI panels, USB-less consumer devices, motor control reference designs (with companion dsPIC), and connectivity-rich embedded control (UART/SPI/I2C bridges). The combination of 23 timers and four UARTs makes it well suited to multi-protocol gateway applications. The 100-TQFP package exposes all 85 I/O pins, enabling direct bus or parallel-master-port interfaces to external peripherals or external memory. Design consideration - when designing with this device, leverage the Peripheral Pin Select system to optimize PCB layout flexibility, but be aware that PPS remapping is set at runtime and must be re-initialized on every reset. For battery-powered applications, the Deep Sleep mode with RTCC retention provides the lowest quiescent current and is preferable over Idle or Run modes. The 100-TQFP package has a larger footprint than 64-pin variants - choose the 100-pin device only when its 85 I/O pins are genuinely required. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet alone, supporting component selection for both new designs and legacy system maintenance.

It integrates 16 channels of 10-bit ADC, up to 85 general-purpose I/O pins, and peripherals including Brown-out Detect/Reset, LVD, POR, PWM, and WDT for robust embedded control. The part carries the -I industrial temperature grade (-40C to +85C) and is part of the PIC24FJ256GA110 family datasheet covering 64 KB to 256 KB Flash variants. A 16-bit microcontroller (MCU) is a programmable computing device that uses a 16-bit data path and instruction word to balance code density, deterministic behaviour, and peripheral integration for embedded systems. PIC24F devices sit in Microchip's 16-bit portfolio between 8-bit PIC16/PIC18 parts and 32-bit PIC32 parts, and they belong to the broader microcontroller > microcontroller IC > semiconductor taxonomy. The 16-bit architecture delivers higher MIPS per MHz than 8-bit cores while remaining easier to learn and tool than 32-bit ARM Cortex-M parts, making PIC24F a common choice for cost-sensitive, low-power, mixed-signal designs. Key features include 32 MHz operation delivering up to 16 MIPS, 64 KB Flash / 16 KB RAM, integrated 16-channel 10-bit ADC, up to 85 GPIO, and multiple serial interfaces (3x I2C, 3x SPI, 4x UART) plus 23 independent timers per the PIC24FJ256GA110 family datasheet. The nanoWatt technology label indicates deep-sleep currents below 100 nA for battery-backed applications. Compared with PIC24FJ128 variants this part uses half the Flash and so is positioned for budget-constrained designs that do not need 128 KB. Architecturally, the PIC24FJ64GA110T-I/PF uses a modified Harvard core with separate program and data buses, a hardware multiply/divide unit, and a peripheral engine capable of running PWM, ADC, and communication blocks independently of the CPU. The 100-TQFP package exposes most pins as GPIO and as alternate-function peripheral mappings, enabling large mixed-signal designs with both analog sensing and digital I/O. Industrial-grade silicon and the 16 MIPS throughput make it suitable for real-time control loops such as BLDC motor commutation, sensor fusion front-ends, and human-interface subsystems. Typical applications include industrial sensor hubs, BLDC and stepper motor control, USB-aware human-interface panels, and low-power remote sensor nodes. Designers also use this family for graphical displays, multi-protocol bridges, and medical/consumer devices that need more than an 8-bit MCU but do not justify a 32-bit part. The tape-and-reel -T suffix indicates factory packaging for SMT assembly lines, and the -I grade supports commercial-to-industrial enclosures.

PIC24FJ64GA412-I/BG

PIC24FJ64GA412-I/BG - 16-bit XLP MCU 64KB Flash 32MHz | Microchip

The Microchip Technology PIC24FJ64GA412-I/BG is a 16-bit PIC24F microcontroller built on the eXtreme Low Power (XLP) architecture with an integrated crypto engine, 64 KB of Flash program memory, and 8 KB of RAM, packaged in a 121-ball Thin Fine-Pitch Ball Grid Array (TFBGA, 10x10 mm). The core runs at up to 32 MHz (8 MIPS with the 4-cycle 16-bit instruction path) and integrates a segmented LCD driver, USB, crypto accelerator, and rich analog/digital peripherals ideal for low-power connected products. A 16-bit PIC microcontroller is a Harvard-architecture MCU that uses separate program and data buses to fetch instructions and operands in parallel, doubling effective throughput versus 8-bit designs at the same clock rate. PIC24F devices in particular target ultra-low-power battery applications thanks to nanoWatt XLP sleep modes (deep sleep, RTC, and retention) that cut quiescent current to single-digit microamps, while still offering large memory and LCD/USB peripherals that 8-bit MCUs cannot match. The PIC24FJ64GA412 sits inside the Microchip PIC24F family, in the GA4xx sub-family focused on general-purpose ultra-low-power designs. Key features include 64 KB (22K x 24) Flash, 8 KB RAM, segmented LCD controller (up to 320 segments), Full-Speed USB 2.0 (host/device/OTG), a hardware crypto engine (AES, DES, SHA), 16-channel 12-bit ADC, multiple UART/SPI/I2C peripherals, and a Real-Time Clock/Calendar. Operating voltage spans 2.0 V to 3.6 V and the device offers multiple low-power modes (Sleep, Deep Sleep, RTC-only) for battery-powered designs. Architecturally, the PIC24FJ64GA412 uses a modified Harvard core with a 16-bit data path, 24-bit instruction word, a 4-deep instruction prefetch queue, and a vectored interrupt controller. The integrated LCD controller directly drives segmented glass without external drivers, the crypto engine offloads AES/SHA from the CPU, and XLP modes allow the chip to wake from sub-microamp sleep on RTC, GPIO, or peripheral events. Typical applications include low-power IoT sensor nodes, secure connected wearables with segmented LCD UIs, industrial HMI panels with integrated glass drivers, battery-powered medical monitoring devices, USB-enabled data loggers, and consumer white goods with display and crypto needs. The 121-TFBGA package suits compact, high-density PCB layouts where a 10x10 mm footprint with controlled-impedance routing is acceptable. When designing with this part, remember that the 121-TFBGA package requires PCB-level design rules (via-in-pad, 0.5 mm ball pitch, reflow profile for lead-free SAC305).

It integrates a hardware crypto engine, multiple communication peripherals, and a segmented LCD driver, making it ideal for secure, low-power, display-driven embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and peripherals onto one die. The PIC24FJ family is a 16-bit modified Harvard architecture microcontroller line within the broader PIC MCU family tree (MCU -> microcontroller -> embedded controller -> semiconductor). The "FJ" suffix denotes the use of Microchip's nanoWatt XLP technology for ultra-low sleep currents in battery-powered applications, while the GA412 subset adds segmented LCD support and a dedicated crypto module for AES/SHA acceleration. Key features include 64 KB (22K x 24 instruction words) dual-partition Flash, 8 KB RAM, segmented LCD driver supporting up to 96 segments, 16-channel 10-bit ADC, five 16-bit timers, six UART, three I2C, three SPI, an RTCC with calendar mode, and a hardware AES/SHA crypto accelerator. The TFBGA-121 (10x10 mm) package provides a thin-profile surface-mount footprint for space-constrained designs. Power consumption is rated in the microampere range during sleep, supporting coin-cell and energy-harvesting applications. The architecture is built on a 16-bit modified Harvard core with a 24-bit instruction word that improves code density versus typical 32-bit MCUs. Wide 16-bit data paths and DSP-class instructions accelerate sensor-fusion and signal-processing tasks. The integrated segmented-LCD charge-pump driver eliminates the need for an external LCD bias generator. The hardware crypto engine offloads AES-128/192/256 and SHA-256 from the CPU, enabling secure firmware updates and tamper-resistant communications. Typical applications include secure IoT sensor nodes, low-power medical monitors with LCD readouts, electronic shelf labels, secure token-based authentication devices, fitness wearables with on-glass displays, and industrial HMI panels. The integrated LCD and crypto blocks allow a single chip to replace a multi-component discrete solution. When designing, plan for I/O multiplexing carefully: the high pin count concentrates peripherals on shared pins. Use the segmented LCD charge pump with proper bypass capacitors per the datasheet, and verify pin assignments for your chosen LCD glass. For low-power designs, leverage the deep-sleep and sleep modes with peripheral wake-up sources rather than polling loops.

The 'E' suffix denotes the extended temperature grade and '/ML' designates the 28-QFN surface-mount package. What is a PIC24F microcontroller? The PIC24F is a family of 16-bit microcontrollers from Microchip Technology designed for ultra-low-power (eXtreme Low Power) embedded applications. The PIC24F core combines a 16-bit modified Harvard architecture with a rich peripheral set including 12-bit ADC at 200 ksps, comparators, CTMU (Charge Time Measurement Unit) for touch sensing, RTCC, and multiple serial interfaces (UART, SPI, I2C). The PIC24F sits in the broader microcontroller taxonomy as: microcontroller -> embedded MCU -> 16-bit MCU -> PIC24 family -> PIC24F sub-family. This positioning makes the PIC24FJ64GA702 a mid-density option for power-constrained designs. Key features of the PIC24FJ64GA702 include eXtreme Low Power modes with deep sleep currents in the microamp range, 22 I/O pins, a 12-bit ADC with up to 14 analog input channels, three analog comparators, DMA for peripheral-to-memory transfers without CPU intervention, ECC Flash for enhanced reliability, and CTMU support for capacitive touch applications. The device integrates a real-time clock and calendar (RTCC) with calendar mode for battery-backed timekeeping. The PIC24FJ64GA702 architecture uses a 16-bit modified Harvard core with a 24-bit instruction word, allowing efficient C code compilation through the MPLAB XC16 toolchain. Internal PLL derives the 32 MHz system clock from an internal 8 MHz source, while the deep-sleep, sleep, and idle modes enable average current draws low enough for coin-cell and energy-harvesting designs. The DMA controller offloads repetitive data movement from the CPU, freeing cycles for application logic. Typical applications include IoT sensor nodes, capacitive touch interfaces, battery-powered industrial sensors, consumer wearables, home automation controllers, and low-power wireless sensor hubs where the 64 KB Flash and 16 KB RAM comfortably host a TCP/IP or BLE stack plus application code. When designing with this device, allocate adequate PCB copper for thermal dissipation in high-MIPS workloads and follow Microchip's MSSP peripheral routing guidelines for SPI/I2C signal integrity. The /ML QFN package requires a thermal pad that must be soldered to a copper pour for both thermal and electrical performance.

The device supports 22 general-purpose I/O pins and includes a DMA controller for low-CPU-overhead data movement. A 16-bit microcontroller (MCU) is a microprocessor with a 16-bit data path, registers, and ALU, occupying the middle ground between 8-bit MCUs (simple control, low cost) and 32-bit MCUs (high performance, complex OS). PIC24F devices sit in the broader PIC microcontroller family hierarchy (PIC10/12/16/18 8-bit -> PIC24F 16-bit -> PIC32MX 32-bit) and are widely used for mixed-signal embedded designs that need more performance than 8-bit parts but not the full overhead of ARM Cortex-M0+. The 'FJ' suffix indicates Flash program memory with eXtreme Low Power (XLP) technology, while the 'GA7xx' family adds USB, graphics, and analog peripherals. Key features of the PIC24FJ64GA702-E/MV include 64KB (22K x 24) self-programmable Flash with ECC, 16KB SRAM, a hardware DMA engine, a 12-bit 200 ksps ADC with up to 14 channels, three comparators, a Charge Time Measurement Unit (CTMU) for touch buttons and sliders, multiple serial interfaces (UART, SPI, I2C), and 22 GPIO pins. The 32 MHz core delivers 16 MIPS while consuming only a few hundred microamps at full speed, making it ideal for battery-powered applications. Architecturally, the PIC24FJ64GA702 uses a modified Harvard architecture with separate program and data buses, a 24-bit instruction word, and a 16-bit data path. The XLP technology includes multiple power-saving modes (Sleep, Idle, Doze) with wake-up times in the microsecond range, while the on-chip DMA engine offloads peripheral-to-memory transfers without CPU intervention. Internal voltage regulation supports 2.0V to 3.6V operation directly from a single lithium cell. Typical applications include IoT sensor nodes, wearable health monitors, low-power wireless HMI controls, capacitive touch user interfaces, battery-powered industrial sensors, USB human-interface devices, and home automation endpoints. The 64KB Flash and 16KB RAM provide ample headroom for protocol stacks such as BLE, LoRa, or sub-GHz radio drivers when paired with an external transceiver. When designing with this MCU, ensure the UQFN-4x4 PCB land pattern follows Microchip's recommended footprint, including thermal vias under the exposed pad. The DMA engine must be configured before activating any DMA-triggered peripheral to avoid spurious transfers, and the CTMU requires periodic calibration for accurate capacitive measurements.

PIC24FJ64GA702-E/SO

PIC24FJ64GA702-E/SO - 16-Bit 32MHz 64KB Flash MCU | Microchip

The Microchip PIC24FJ64GA702-E/SO is a 16-bit microcontroller from the PIC24F family featuring a 32 MHz CPU speed (16 MIPS), 64 KB (22K x 24) of ECC Flash program memory and 8 KB of RAM, housed in a 28-pin SOIC (SO) wide-body 300-mil package. The part integrates a 12-bit ADC at 200 ksps, multiple timers, comparators, CTMU for touch applications, DMA, and a rich serial peripheral set including UART/SPI/I2C. The extended-temperature (-E) suffix supports -40C to +125C operation, making this device suitable for industrial-grade designs. A 16-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a wide range of peripherals onto a single silicon die. The PIC24F family belongs to Microchip's broader 16-bit DSC/MCU portfolio, which itself falls into the wider category of embedded microcontrollers within semiconductors. 16-bit MCUs occupy the middle ground between 8-bit parts (cost-optimized, low power) and 32-bit ARM Cortex-M cores (highest performance), offering deterministic interrupt response and richer math for sensor and motor control while still fitting cost-sensitive designs. Key features include eXtreme Low Power (XLP) operation with multiple sleep modes, peripheral pin select (PPS) for flexible I/O mapping, an integrated charge time measurement unit (CTMU) for capacitive touch sensing, a 12-bit ADC with up to 14 analog inputs at 200 ksps, three analog comparators, and a direct memory access (DMA) controller that offloads data movement from the CPU. The 64 KB ECC Flash improves reliability in harsh environments by detecting and correcting single-bit errors in program memory. The architecture is a modified Harvard design with separate program and data buses, allowing simultaneous instruction fetch and data access. The 32 MHz core delivers 16 MIPS with deterministic 4-cycle instruction execution, and the integrated DSP engine (in higher-tier family members) accelerates math-intensive tasks such as motor control loops and digital filters. The result is an MCU that can handle both general-purpose control and signal-processing tasks without external components. Typical applications include industrial sensor interfaces, capacitive touch user interfaces, low-power IoT edge nodes, portable medical instruments, and automotive body/chassis subsystems (note: the -E grade here is industrial, not AEC-Q100 automotive; the -I grade is industrial). The wide operating voltage range of 2.0 V to 3.6 V makes it well suited to battery-powered designs where a single Li-Ion cell must be regulated down efficiently. When designing with this device, prioritize PPS to route peripherals to convenient pins, and use the XLP sleep modes aggressively for battery applications: deep sleep current is in the microamp range. Ensure the 28-SOIC footprint has adequate copper area for thermal dissipation even though peak power is low, and follow Microchip's AN1066 for IEC 61000-4-4/6 EMC layout recommendations if the design will be deployed near noisy industrial loads.
