PIC24FJ128GA610-E/PT

PIC24FJ128GA610-E/PT - 16-Bit 32MHz 128KB Flash MCU | Microchip

The Microchip Technology PIC24FJ128GA610-E/PT is a 16-bit PIC24F microcontroller with 128 KB Flash, 32 KB RAM, and a 32 MHz CPU core, housed in a 100-pin TQFP (12x12 mm) package. The -E/PT suffix denotes the -40C to +125C extended-temperature grade suitable for AEC-Q100 automotive and harsh-environment designs. The device integrates dual-partition Flash with Live Update for in-field firmware swap without downtime, plus a CTMU charge-time measurement unit for capacitive touch and a parallel master port (PMP) for graphics or external memory expansion. A 16-bit microcontroller (MCU) is a single-chip computer with a 16-bit data path, register width, and ALU, providing roughly an order-of-magnitude higher throughput and code density than 8-bit MCUs at the same clock rate. The PIC24F family sits within Microchip’s 16-bit MCU hierarchy (PIC24F → PIC24 → dsPIC → 16-bit MCU → embedded microcontroller → semiconductor IC) and is optimized for low-power, mixed-signal embedded designs. Typical supply is 2.0-3.6 V with multiple low-power sleep modes drawing microamp-level currents. Key features include 85 programmable I/O pins, an integrated 16-channel 10-bit ADC, four comparators, six UART, three SPI, three I2C, IrDA, LIN bus, and PMP connectivity, plus a real-time clock calendar (RTCC) with backup. The 100-pin TQFP provides ample pin budget for parallel displays, multiple serial buses, and analog signal conditioning simultaneously. The dual-partition Flash architecture allows a bootloader to overwrite the active image while the other partition continues running, eliminating production-line downtime. Technical depth: the PIC24FJ128GA610 uses a modified Harvard architecture with a 16-bit wide instruction path, 24-bit wide data path, and a 7-stage pipeline. The 32 MHz core delivers 16 MIPS (Dhrystone 2.1) and includes a 16x16 hardware MAC. The CTMU integrates constant-current sources for capacitive touch sensing, while the PMP supports up to 16-bit parallel interfaces to external memory, graphics controllers, or FPGA data ports. The RTCC, with on-chip 32 kHz domain, supports calendar-mode timestamp without external components. Typical applications include industrial control with HMI panels, portable medical/fitness devices with capacitive touch, automotive body and sensor modules, USB device interfaces, secure industrial IoT edge nodes, and battery-powered data loggers. The Live Update Flash feature is especially valuable in industrial installations where firmware must be updated without shutting down the controlled process. When designing with the PIC24FJ128GA610-E/PT, plan the PCB layout for the 100-pin TQFP (0.5 mm pitch) and use a 4-layer stackup with a continuous ground plane under the IC to keep switching noise out of the analog sections. Decouple VDD/VSS pairs locally with 100 nF X7R ceramics plus a 4.7 uF bulk tantalum, and route the 32 kHz crystal traces short and guarded to preserve RTCC accuracy. This page synthesizes distributor pricing, AEC-Q100-qualified drop-in alternatives, and Live Update design notes not found in a single source, giving procurement and firmware teams a faster decision path than the 232-page datasheet alone.

This CMOS device integrates a rich peripheral set including multiple UART, SPI, I2C and IrDA interfaces, plus configurable logic cells (CLC), an LCD driver, a Charge Time Measurement Unit (CTMU), a Real-Time Clock and calendar, and a 10-bit ADC and DAC for mixed-signal designs. The 'T' suffix denotes tape-and-reel packaging, 'I' is the industrial temperature grade (-40 C to +85 C), and 'BG' is the 121-ball TFBGA package code. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a broad set of peripherals. Within the broader taxonomy it sits at: microcontroller -> embedded controller -> 16-bit MCU -> RISC MCU -> PIC24F family -> semiconductor. The PIC24F architecture uses a 16-bit modified Harvard core with a 16-element working register array, enabling most instructions to execute in a single cycle and giving the family its headline 16 MIPS performance at 32 MHz. Its peripheral pin-select (PPS) remapping feature lets designers route digital functions to a wide range of physical pins, simplifying PCB layout. Key features of the PIC24FJ128GA610 include 128 KB Flash, 32 KB RAM, hardware multiplier and divider, DMA, RTCC with backup power, an integrated LCD driver supporting up to 480 segments, a 10-bit 1.1 Msps ADC with up to 32 analog inputs, multiple capture/compare/PWM modules, and a CTMU for capacitive touch and time measurement.

The XLP Sleep mode draws single-digit microamp currents, and the integrated RTCC keeps time while the core is asleep. The 28-SOIC package is the wide-body 300-mil version, suitable for hand-soldering prototypes and production. From an architectural perspective, the PIC24F core uses a 16-bit modified Harvard architecture with a 24-bit instruction word, giving higher code density than 8-bit PICs while staying much lower-cost than 32-bit Cortex-M parts. The DMA controller lets peripherals move data autonomously, freeing the core for application logic and improving real-time response. Typical applications include low-power IoT sensor nodes, portable medical devices, capacitive touch HMI panels, industrial control nodes, and consumer devices that need USB or LCD interfaces. The 28-pin variant is particularly well suited to cost-sensitive products that need the peripherals of the PIC24F GA family but do not require the higher pin count of the 44/64-pin siblings. Design considerations include selecting the proper operating voltage range (2.0 V to 3.6 V), providing adequate decoupling (100 nF + bulk caps near VDD), and routing the analog ADC inputs away from switching signals to preserve SNR. When migrating from 8-bit PIC MCUs, engineers should note the 24-bit instruction width and update toolchains to MPLAB X with the XC16 compiler.

A 16-bit microcontroller (MCU) is a programmable processor with internal Flash, RAM, and peripherals integrated on a single die. Within the embedded taxonomy, the PIC24FJ family sits between 8-bit PIC16/PIC18 MCUs and 32-bit PIC32 ARM Cortex parts. The PIC24F line emphasizes low-power eXtreme Low Power (XLP) variants with the Harvard architecture, providing deterministic instruction cycles for real-time control. USB OTG enables the device to act as both USB host and peripheral without an external PHY, which is uncommon in this price/performance tier. Key features include an 8 MHz internal oscillator with 4x PLL (yielding 32 MHz core), 17-bit single-cycle hardware multiplier, 16-bit hardware divider, and C compiler-optimized instruction set. The CTMU module supports touch sensing, mTouch capacitive buttons, and time-of-flight measurement, while the PMP/EPSP modules drive parallel displays. Five 16-bit timers/counters, four UARTs, two SPI, and two I2C peripherals cover typical wired connectivity. The architecture combines modified Harvard separation of program and data buses with a 16-bit working register array, delivering up to 16 MIPS while drawing microamp sleep currents. The integrated USB OTG PHY supports full-speed (12 Mbps) host and device roles, plus low-speed (1.5 Mbps) device mode, with internal pull-up/pull-down resistors selectable by firmware. Typical applications include USB peripherals (HID, CDC, MSD), industrial control with capacitive touch HMIs, portable data loggers with RTC, embedded host products (USB flash drive readers, keyboards), and medical monitoring devices needing low sleep current. The wide 2.0V-3.6V supply range also supports battery-powered IoT sensor nodes. Design with this MCU by allocating a minimum 1 µF bulk decoupling capacitor on VDD and 100 nF on each AVDD pair; place the 32 kHz crystal within 1 cm of SOSCO/SOSCI to minimize RTC drift. USB D+/D- traces must be 90 ohm differential, length-matched within 2 mm, and routed over a continuous ground plane. The 'T' suffix indicates Tape & Reel packaging; the operating range is industrial -40C to +85C (I-grade).

PIC24FJ128GB202-E/MM

PIC24FJ128GB202-E/MM - 16-bit XLP MCU, 128KB Flash, USB, Crypto | Microchip

The Microchip Technology PIC24FJ128GB202-E/MM is a 16-bit microcontroller from the PIC24F eXtreme Low Power (XLP) family, integrating a hardware crypto engine, USB 2.0 full-speed device/host/OTG, and 128 KB of self-programmable Flash in a 28-pin 6x6 mm QFN-S package. It operates at up to 32 MHz MIPS core clock with 8 KB SRAM and is engineered for ultra-low-power embedded designs where both cryptographic acceleration and USB connectivity are required on the same die. A 16-bit microcontroller (MCU) is a programmable processor whose arithmetic logic unit, registers, and internal bus are 16 bits wide, balancing the 8-bit MCU's code density with the 32-bit MCU's throughput. PIC24F devices sit in Microchip's mid-range 16-bit portfolio between 8-bit PIC16/PIC18 parts and 32-bit PIC32 parts, sharing the same MPLAB X toolchain, XC16 compiler, and Harmony framework as the wider dsPIC/PIC24/PIC32 family. The "FJ" prefix denotes Flash program memory with the XLP sleep architecture, "GB" denotes integrated USB plus crypto, and "202" identifies the 28-pin pinout with 128 KB Flash. Key features of the PIC24FJ128GB202-E/MM include: 128 KB (43K x 24) Flash program memory with self-programming and live update, 8 KB SRAM, integrated hardware crypto engine supporting AES, DES, 3DES, SHA-1/SHA-256 and RNG, USB 2.0 FS device/host/OTG with on-chip transceiver and PHY, two I2C, two SPI, up to two UART, two comparators, a 10-bit ADC with up to 9 channels, 5-bit DAC, three 16-bit timers, RTCC with calendar, and a chargeable nanoWatt XLP deep-sleep mode drawing sub-µA currents. The on-chip 32 kHz crystal-less USB PLL and the CTMU touch-sensing peripheral reduce external BOM cost. The QFN-S (6x6 mm) package provides a thermally efficient exposed paddle suitable for hand-held and USB-powered devices. The PIC24FJ128GB202 architecture pairs a modified Harvard CPU with a 24-bit instruction word for compact code density, a single-cycle hardware multiplier, and a deterministic interrupt controller. The integrated crypto block offloads AES-128/192/256 and SHA operations from the core, so secure firmware updates, signed firmware boot, and TLS-style handshakes run in milliseconds rather than tens of milliseconds. The USB block shares DMA with the rest of the peripherals and supports device, host, and OTG roles, eliminating the need for an external PHY in most token, HID, CDC, and Mass Storage designs. Typical applications for this part include USB smart-card and authentication tokens, secure medical data loggers with USB charging/docking, encrypted industrial sensor hubs that stream over USB, low-power IoT edge nodes that need both USB firmware update and secure boot, e-metering and tamper-resistant metering devices, and battery-powered consumer accessories such as USB-C hearables and wearables. Designers choose the "E" temperature grade (-40C to +125C) for industrial and extended-temperature environments. A practical design tip: route the USB D+/D- pair as a 90-ohm differential microstrip with ground stitching vias on both sides, keep the 27-ohm series resistors within 4 mm of the IC, and place the VBUS bulk capacitor as close as possible to the VBUS pin to pass USB compliance and ESD tests. The QFN exposed paddle must be soldered to a continuous ground copper pour with thermal vias to meet the 1.5 W dissipation budget in enclosed industrial enclosures.

The integrated USB OTG PHY eliminates an external transceiver, and the dedicated crypto engine offloads AES/DES operations from the CPU, allowing real-time encryption at low MHz clock rates. The peripheral pin-select (PPS) mapping provides flexible digital assignment to a fixed pin count. Typical applications include secure IoT sensor nodes, automotive secure telematics (LIN/CAN slave bridges), USB HID peripherals with hardware crypto, secure access-control readers, battery-powered wireless sensor endpoints with USB charging, and tamper-resistant medical accessories. The combination of XLP sleep modes and integrated crypto makes it especially suitable for products needing long battery life and hardware-level data protection. When designing with this part, ensure that the 3.3 V rail is regulated within +/-5% and that the VUSB/VDD core supply sequencing follows the datasheet guidelines to keep the crypto engine stable.
