MPN: PIC24FJ256DA110-I/BG ✓ פעילPIC24FJ256DA110-I/BG סקירה
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a rich set of peripherals such as timers, ADC, communication controllers, and GPIO. The PIC24FJ256DA110 belongs to the PIC24F family of low-power 16-bit flash microcontrollers, which sits in Microchip's broader 16-bit MCU portfolio; this hierarchy is PIC24F -> PIC24 -> 16-bit MCU -> microcontroller -> embedded computing -> semiconductor. The 'DA' sub-family is the one that adds the dedicated graphics controller and the 'GB' sub-family adds USB OTG; together the DA family targets graphical user-interface applications.
Key differentiating features of the PIC24FJ256DA110-I/BG include its on-chip 3-layer graphics controller with hardware acceleration for line, rectangle, and text rendering; a charge time measurement unit (CTMU) for touch sensing; an integrated full-speed USB 2.0 OTG controller; and Microchip's Peripheral Pin Select (PPS) which remaps most digital peripherals to a wide choice of I/O pins. The device also integrates a 16-channel 10-bit ADC, multiple UART/SPI/I2C peripherals, a Real-Time Clock and Calendar (RTCC), and a JTAG interface for boundary scan and In-Circuit programming.
Typical applications for the PIC24FJ256DA110-I/BG are color TFT-LCD graphical user interfaces, industrial HMI panels, USB-equipped data loggers, medical patient-interface displays, and consumer appliances requiring a small color screen. Its 32 MHz core plus 256 KB flash is sized for storing full graphical framebuffers plus application code, while the 121-ball BGA enables compact board layouts where board area is at a premium.
When designing with this part, allocate sufficient PCB area for BGA fan-out and follow Microchip's recommended land pattern; the 'I' suffix denotes the -40C to +85C industrial temperature range and '/BG' specifies the 121-ball TFBGA package.

יישומים טיפוסיים
PIC24FJ256DA110-I/BG מתאים עבור 6 יישוםs: Color TFT HMI Control Panel, Industrial Data Logger with USB, Medical Patient-Interface Display, USB-Equipped Home Appliance Controller, Portable Measurement Instrument, Automotive-Grade Infotainment Sub-Display.
Color TFT HMI Control Panel
The PIC24FJ256DA110-I/BG is purpose-built for color TFT HMI panels: the integrated graphics controller accelerates line, rectangle, and text rendering, allowing a 32 MHz CPU to drive a 4.3-inch WQVGA 480x272 display smoothly. Designers pair the MCU with a small SPI TFT and use the 256 KB flash for application code plus bitmap assets, while the 24 KB SRAM holds the framebuffer and font tables. The integrated USB OTG enables firmware updates and diagnostic logging from a USB stick on the factory floor.
מומלץ
Industrial Data Logger with USB
Engineers use the PIC24FJ256DA110-I/BG in industrial data loggers because the USB 2.0 Full-Speed OTG controller lets the device appear as a Mass Storage device when plugged into a host PC, so collected sensor data can be retrieved without special drivers. The 10-bit ADC with multiple channels digitizes thermocouple or 4-20 mA inputs, the RTCC timestamps every record, and the 256 KB flash stores weeks of compressed log data. The -40C to +85C industrial temperature range supports factory-floor deployment.
מומלץ
Medical Patient-Interface Display
In medical patient-interface equipment the PIC24FJ256DA110-I/BG drives a small color TFT that shows vital-sign trends, alarm icons, and configuration screens. The integrated graphics controller keeps CPU headroom available for the safety-critical monitoring loop while still updating the screen at full frame rate. The 24 KB SRAM and Peripheral Pin Select allow capacitive touch sensing via the CTMU and a dedicated I2C touchscreen controller on the same MCU.
מומלץ
USB-Equipped Home Appliance Controller
Consumer appliances such as smart ovens, coffee machines, and washing-machine controllers use the PIC24FJ256DA110-I/BG to drive a small TFT status panel and expose a USB port for firmware upgrade or service diagnostics. The USB OTG controller in device mode emulates a flash drive so technicians can drop new firmware without opening the chassis, and the 256 KB flash accommodates multi-language UI assets plus the appliance control loop. The BGA-121 package enables very compact board layouts behind the display.
מומלץ
Portable Measurement Instrument
Handheld test and measurement instruments use the PIC24FJ256DA110-I/BG as the main controller because the integrated graphics controller renders waveforms, menus, and readings on a small TFT without burdening the CPU. The 16 MIPS PIC24F core is fast enough for FIR-filtered sensor reads, the 24 KB SRAM holds a circular waveform buffer, and the 256 KB flash stores calibration tables plus multiple UI languages. USB OTG allows instrument log export to a PC.
מומלץ
Automotive-Grade Infotainment Sub-Display
While the PIC24FJ256DA110-I/BG is rated -40C to +85C and is not AEC-Q100 qualified, similar designs use it for non-safety in-cabin sub-displays such as rear-seat entertainment controllers and HVAC panel TFTs. The integrated graphics controller draws icons and progress bars smoothly, USB OTG plays media files from a USB stick, and the PPS remaps digital peripherals to simplify PCB routing in tight enclosures. The 121-ball TFBGA enables placement on the back of the display module.

הערות תכנון
The PIC24FJ256DA110-I/BG uses a 121-ball TFBGA at 10x10 mm with a fine 0.8 mm pitch. Use Microchip's recommended land pattern, NSMD (non-solder-mask-defined) pads, and a 4-6 mil solder paste stencil; via-in-pad with copper fill and planarization is recommended for reliable BGA assembly. Plan escape routing for at least two outer rows on all four sides to break out to a 4-layer PCB.
Place 0.1 uF decoupling capacitors as close as possible to every VDD/VSS pair, plus a bulk 4.7-10 uF tantalum or ceramic capacitor on the main VDD rail within 5 mm of the BGA. The PIC24FJ has separate analog and digital supply pins (AVDD/AVSS); dedicate a 10 uH ferrite bead or RC filter between VDD and AVDD to keep digital switching noise out of the ADC measurements, per Microchip's PIC24FJ256DA210 family datasheet power section.
The USB OTG D+ and D- traces must be 90 ohm differential, length-matched within 150 mil, and routed over a continuous ground plane; place the 27 ohm series termination resistors and the 1.5 kohm pull-up on D+ as close to the MCU balls as possible. The graphics controller's TFT data lines should be length-matched within 1 inch and isolated from switching power traces to avoid on-screen artifacts.
Estimated: at 32 MHz core clock with full USB OTG activity and the graphics controller updating the display continuously, expect roughly 35-45 mA core current plus peripheral I/O - design the VDD regulator for at least 75 mA headroom. Do not enable the JTAG pins as GPIO without first disabling boundary scan in the configuration registers, or the debugger will be unable to attach after programming.
The 121-ball TFBGA has good top-side heat dissipation via the inner balls and exposed center pad pattern; connecting all VSS balls and routing thermal vias under the package to an inner ground plane reduces theta_JA significantly for hot-spot environments. For sealed enclosures without airflow, derate the core clock or add a small copper heat-spreader on the back of the display module.
