PIC24FJ1024GB610-I/PT Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one die. The PIC24F family uses Microchip's modified Harvard 16-bit RISC architecture with 16 working registers, providing deterministic interrupt response and code density suitable for C and assembly development. Within the power-managed hierarchy, this part sits at the convergence of low-power MCU and USB-capable connectivity, making it a frequent choice for portable and connected devices.
Key features of the PIC24FJ1024GB610-I/PT include 1 MB (341.5K x 24) of dual-partition Flash supporting live updates and bootloader partitioning, 32 KB of SRAM, hardware USB OTG with on-chip transceiver, an integrated LCD driver, and a rich peripheral set including multiple UART, SPI, I2C, and 16-bit timers. The 100-pin TQFP package exposes the maximum pin count of the family, enabling access to most peripheral functions simultaneously.
The architecture combines a 16-bit data path with 24-bit instruction words, dual-partition Flash for field firmware upgrades without downtime, and code-guard security for IP protection. Integrated peripherals include a 16-channel 12-bit ADC, comparators, RTCC, and PWM. The eXtreme Low Power features (sleep, Deep Sleep, and Retention modes) make it suitable for battery-powered designs.
Typical applications include industrial control with graphical LCD HMIs, USB peripherals and embedded hosts, IoT gateways, portable medical devices, and automotive infotainment sub-systems. The combination of large Flash, USB OTG, and extensive peripherals supports designs previously requiring an external memory bus.
When designing with this device, plan Flash partitioning early to avoid costly layout or firmware rework. The 100-pin TQFP package provides generous I/O but requires a 4-layer PCB for clean USB routing; impedance-matched differential pairs are mandatory for USB-OTG compliance.

Typical Applications
PIC24FJ1024GB610-I/PT is suitable for 6 applications: Industrial Control with Graphical HMI, USB Peripherals and Embedded Hosts, IoT Gateway and Edge Devices, Portable Medical Devices, Automotive Infotainment Subsystems, Consumer Audio and USB Headsets.
Industrial Control with Graphical HMI
The PIC24FJ1024GB610-I/PT suits industrial HMIs because its 1 MB Flash stores large graphical assets, fonts, and multi-language strings while the integrated LCD driver simplifies the segment/character display interface. The 16 MIPS performance at 32 MHz supports smooth menu rendering and real-time control loop execution. Its 32 KB SRAM buffers touch input and fieldbus frames without external memory. Place the MCU between the keypad input matrix and the LCD, with the USB port optionally used for firmware updates.
Recommended
USB Peripherals and Embedded Hosts
The PIC24FJ1024GB610-I/PT is purpose-built for USB peripherals because it integrates a Full-Speed USB 2.0 OTG controller with on-chip transceiver, removing external analog and saving PCB real estate. The 1 MB Flash holds USB stacks such as Microchip's MLA while the 32 KB SRAM supports HID, CDC, and vendor-class frames. Power sequencing for VBUS sensing is built in, simplifying battery-powered and bus-powered designs. Place a 90.9 ohm differential pair from D+/D- to the USB connector with a ferrite bead on VBUS.
Recommended
IoT Gateway and Edge Devices
The PIC24FJ1024GB610-I/PT fits IoT edge nodes because its eXtreme Low Power modes reduce quiescent current to single-digit microamps between sensor reads, and the 16 MIPS core handles MQTT-SN, TLS, or custom protocol stacks resident in 1 MB Flash. Dual-partition Flash enables secure OTA updates without downtime. UART/SPI/I2C peripherals connect to radios, sensors, and EEPROMs. Use the Deep Sleep mode between scheduled wake-ups to extend battery life while the integrated RTCC tracks time accurately.
Recommended
Portable Medical Devices
The PIC24FJ1024GB610-I/PT supports portable medical applications because the eXtreme Low Power technology keeps battery use low while the 12-bit ADC and 16 analog channels capture multiple biosignals simultaneously. The 1 MB Flash stores FDA-required firmware with version history in dual partitions, while 32 KB SRAM buffers samples before transmission. The integrated LCD driver shows patient data on a segment display. Operate from two AA cells (3.0 V) within the 2.0-3.6 V supply range.
Recommended
Automotive Infotainment Subsystems
The PIC24FJ1024GB610-I/PT works in automotive infotainment sub-assemblies because its USB OTG port connects to phones for media playback while the integrated LCD driver controls the dashboard display and the 1 MB Flash holds audio codecs and UI assets. The 16 MIPS core manages CAN/LIN bridging via UART/SPI. The industrial -40C to +85C grade covers cabin environments; for under-hood use a Q-grade automotive part is required instead.
Recommended
Consumer Audio and USB Headsets
The PIC24FJ1024GB610-I/PT is well-matched to USB audio products because the integrated USB OTG controller streams 16-bit PCM at full speed without an external codec interface, while the 1 MB Flash holds USB Audio class firmware and DSP routines. The 32 KB SRAM manages audio buffers and the 16 MIPS core processes volume control and LED feedback. The low-power modes save battery life in wireless headsets. Use the on-chip PWM for LED status indication on the headset.

Key Differentiators
- Integrated USB 2.0 Full-Speed OTG with on-chip transceiver (vs PIC24FJ1024GA610-I/PT)
- Dual-partition Flash for live firmware updates (vs PIC24FJ1024GA610-E/PT)
- eXtreme Low Power technology with Retention Sleep (vs PIC24FJ1024GA610T-I/PT)
Design Notes
Use a 4-layer PCB stack-up for the PIC24FJ1024GB610-I/PT USB-OTG design. Route D+ and D- as a 90 ohm differential pair with matched length within 150 mil, and place the ferrite bead on VBUS within 5 mm of the connector. Keep the 32 kHz crystal traces short and guarded by GND to minimize oscillator pickup. Place decoupling capacitors (0.1 uF and 1 uF) within 3 mm of each VDD pin.
Estimated: at 32 MHz full-speed CPU with USB active, core current is approximately 30-40 mA. Add 10 mA budget for USB transceiver and analog peripherals. Use a low-dropout regulator with at least 100 mA headroom; the 3.3 V rail must hold within +/-3% during USB suspend/resume transitions or the USB controller may detect an invalid VBUS level.
Do not assume the GA and GB variants are interchangeable in firmware; GA610 lacks the USB OTG registers and clock configuration bits. If USB is unused, choose the GA variant to save cost. Conversely, do not program a GA610 with GB610 USB initialization code - it will hang on missing register reads. Verify the silicon revision via the DEVSN field before flashing production firmware.
