PIC24FJ256GB610-E/BG - 16-Bit 32MHz 256KB Flash MCU | Microchip
MPN: PIC24FJ256GB610-E/BG ✗ Cuối đờiPIC24FJ256GB610-E/BG Tóm tắt
What is a PIC24F microcontroller? The PIC24F is Microchip's 16-bit MCU family built on a modified Harvard architecture with a 16-bit datapath and 24-bit instruction word, sitting between 8-bit PIC16/PIC18 MCUs and 32-bit PIC32 devices. It targets low-power (eXtreme Low Power, XLP) and USB-enabled embedded applications, balancing deterministic interrupt latency with rich connectivity (USB OTG, UART, SPI, I2C) - a category typically used in consumer, industrial, and automotive body-electronics designs.
Key features include six UART modules, three I2C and three SPI interfaces, six PWM channels with capture/compare, a 10-bit 1.1 Msps ADC, a Real-Time Clock/Calendar, and a full-speed USB 2.0 On-The-Go controller with PHY. The dual-bank Flash with ECC and Live Update allows field firmware upgrades without downtime, a critical feature for remote sensors and automotive modules requiring in-service reprogramming.
Architecturally, the device combines a single-cycle 16-bit ALU with a hardware multiply/divide engine and a DMA-free peripheral set. The XLP deep-sleep current (typical values vary by mode) supports years of battery life when paired with an external RTC and sleep-wake peripheral triggers, while the 85 GPIO pins and extensive interrupt-on-change logic enable complex human-machine interface and sensor-fusion front-ends.
Typical applications include USB-OTG peripherals, automotive body controllers, industrial HMI panels, smart energy metering, and portable medical instrumentation. The wide extended temperature range and AEC-Q100 qualification suitability make the PIC24FJ256GB610 family attractive for under-hood automotive nodes and outdoor industrial installations.
When designing with this MCU, allocate the 0.80 mm BGA ball pitch carefully - it requires HDI PCB fabrication (laser-drilled microvias) and precise reflow profiling. The Live Update feature must be enabled in the configuration words and requires the dual-partition linker script; firmware teams should plan application layout for safe A/B image swap before deployment.

Ghi chú thiết kế
Estimated: The 121-TFBGA uses a 0.80 mm ball pitch on a 10x10 mm body, which requires HDI PCB fabrication with laser-drilled stacked microvias to escape the inner rows. Use 1 oz copper on outer layers and 0.5 oz on inner layers; keep microvia aspect ratio below 0.75:1. Place 100 nF + 10 uF decoupling within 5 mm of each VDD/VSS pair, and route the USB D+/D- pair as a 90 ohm differential with continuous ground reference and length matching PCB layout guidelines for USB 2.0.
The PIC24FJ256GB610-E/BG operates from 2.0 V to 3.6 V. Use a low-dropout regulator with < 50 uVrms noise to feed VDD, and add a ferrite bead + 1 uF cap on the analog AVDD rail if the ADC is active. The VUSB pin requires its own 3.3 V supply derived from VBUS or the internal regulator; tie VBUS to the USB connector VBUS through a divider for OTG session detection. Decouple VBAT/RTC supply separately if battery backup is implemented.
Do not confuse -E/BG (extended -40C to +125C, automotive AEC-Q100) with -I/BG (industrial -40C to +85C) - the wrong suffix voids automotive qualification. The Live Update feature requires the dual-partition linker script and configuration-word settings; firmware teams must verify A/B image swap with a watchdog-driven rollback path before deploying OTA updates. Finally, note that the GB610 family is in NRND status - new designs may want to evaluate the active GA610 or 1024 GB610 variants for long-term availability.
