PIC24FJ256DA206-I/PT - 256KB Flash Graphics MCU | Microchip
MPN: PIC24FJ256DA206-I/PT ✓ Hoạt độngPIC24FJ256DA206-I/PT Tóm tắt
A 16-bit microcontroller (MCU) is a microprocessor optimized for embedded control, providing a balance of computational throughput, low power consumption, and integrated peripherals. PIC24F devices use eXtreme Low Power (XLP) technology and 16-bit modified Harvard architecture that splits program and data memory paths for single-cycle instruction fetch. Within the embedded hierarchy, PIC24F MCUs sit between 8-bit PIC16/PIC18 controllers and the 32-bit PIC32MX/dsPIC families, targeting human-machine interface (HMI) and graphics applications where higher throughput than 8-bit is required.
Key features include 256 KB self-programmable Flash (85.5K x 24 words), 96 KB RAM, hardware graphics controller with direct TFT panel drive up to 4.3-inch WQVGA (480x272), integrated USB OTG with full-speed PHY, hardware crypto engine, peripheral pin select (PPS) for flexible I/O mapping, and 16-bit timers with input capture and output compare. The device supports operating voltage 2.2V to 3.6V and industrial temperature range -40C to +85C.
The PIC24FJ256DA206 uses Microchip's nanoWatt XLP power management with multiple idle and sleep modes including Deep Sleep (SLEEP<0.6 uA typical), enabling battery-friendly designs. The integrated Charge Time Measurement Unit (CTMU) provides capacitive touch sensing, while the parallel master port (PMP) and graphics controller directly drive TFT displays without external graphics RAM for small panels. Hardware AES/SHA crypto and true random number generator (RNG) support secure applications.
Typical applications include graphical user interfaces for industrial control panels, medical device displays with touch, USB-enabled consumer products, point-of-sale terminals with integrated graphics, secure connected devices requiring hardware crypto, and low-power battery-operated HMI nodes. The integrated graphics controller eliminates the need for an external display driver IC in many designs.
When designing with this device, reserve one I/O pin for the programming/debug interface (PGECx/PGEDx) and use the parallel master port (PMP) pins carefully - not all are remappable through PPS. For low-power designs, route wake-up sources to change notification or interrupt-on-change pins and use Deep Sleep mode with RTCC running for sub-microamp standby current.

Ghi chú thiết kế
Estimated: at VDD=3.3V with all peripherals running and full-speed CPU (16 MIPS), supply current is approximately 25-35 mA; USB current adds another ~25 mA in active mode. For USB bus-powered designs, ensure the host can supply 100 mA (default USB) or 500 mA (after enumeration). In Deep Sleep with RTCC running, the part draws <0.6 uA typical, making it suitable for years-long battery life on coin cells when wake-ups are infrequent.
Place the 10 uF decoupling capacitor on VDD pins (6,21,31) and 0.1 uF ceramic on every VDD/VSS pair within 5 mm of the pin. The USB D+/D- traces must be 90 ohm differential, length-matched within 2 mm, and routed over a continuous ground reference plane. The 32.768 kHz crystal traces on SOSC0/SOSC1 should be short and guarded by ground pour to minimize load capacitance drift.
The VUSB pin (pin 33) requires a 220 nF decoupling capacitor and cannot be used as a generic I/O when USB is enabled. JTAG pins TMS/TCK/TDI/TDO are multiplexed with RP22/RP21/RP20/RP23 (RC7/RC6/RC5/RC8) - disabling JTAG via configuration bits frees these for general PPS use but disables the standard debug interface. PMP pins are NOT all remappable through PPS - pins RE0-RE7 and RD0-RD7 are fixed-function PMP and must be routed accordingly when driving a TFT panel.
Route TFT data lines (RD0-RD7, RF0-RF7) and control lines (RE0-RE7) as parallel traces with matched lengths and a continuous ground reference underneath to maintain signal integrity at the panel interface. For touch electrodes driven by CTMU, route the touch lines away from high-frequency digital lines and keep the touch area clear of ground plane cuts. Add a ground ring around the touch sensor for noise immunity.
USB D+/D- require 90 ohm differential impedance and 27 ohm series resistors close to the MCU. If the panel interface is long (>100 mm), add series resistors (22-33 ohm) on PMP data lines to dampen reflections. For TFT pixel clock rates up to 20 MHz, the parallel master port is sufficient; for higher refresh rates consider an external graphics controller IC.
Thông tin tuân thủ
RoHS compliant per Microchip product page; AEC-Q100 qualification is not applicable for the -I (industrial) variant - automotive applications should check Microchip's PIC24FJ DA automotive part numbers separately.
