PIC24FJ128GA610T-I/BG 概述
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 121-ball TFBGA package offers the largest pin count of the GA610 family, exposing the maximum number of I/O, peripheral and analog channels.
The PIC24FJ128GA610 uses a low-power modified Harvard architecture with a wide operating voltage range of 2.0V to 3.6V, multiple power-saving modes (Sleep, Idle, Doze), and a low-power RTCC that can run from a backup coin cell. The 16 MIPS throughput is delivered through a single-cycle instruction path and a hardware multiply/divide engine, while DMA offloads data movement from the CPU for high-throughput peripheral streams.
Typical applications include graphical user interfaces (GUI) with integrated LCD, low-cost touch sensing for white goods and consumer appliances, industrial control panels, USB host/device connectivity (in combination with the GB610 companion variant), sensor hubs, home automation gateways, and medical handhelds. The combination of large memory, ample I/O and integrated analog makes it well suited to single-chip product designs that previously required an external MCU plus companion logic.
When designing with this part, carefully plan the PCB escape routing for the 0.8 mm pitch BGA balls: a 4-layer board with microvia-in-pad is recommended for clean fan-out. Decouple every VDD/VSS pair with 100 nF X7R capacitors placed as close as possible to the balls, and add a single bulk 4.7 uF to 10 uF tantalum or ceramic capacitor near the regulator. Use the PPS feature to simplify routing but verify signal integrity on high-speed SPI or I2S lines routed near analog inputs.

典型应用
PIC24FJ128GA610T-I/BG 适用于 6 应用s: Industrial Human-Machine Interface (HMI) with LCD, Capacitive Touch Control for White Goods, USB-Enabled Sensor Hub / Data Logger, Battery-Backed Metering / Smart Energy, Medical Point-of-Care Diagnostic Reader, Automotive Body and HVAC Control Module.
Industrial Human-Machine Interface (HMI) with LCD
The PIC24FJ128GA610T-I/BG's 128 KB Flash, integrated LCD driver (up to 480 segments), and 32 KB SRAM make it ideal for industrial HMI panels with monochrome graphical LCDs. The 121-ball TFBGA exposes up to 32 analog inputs and the full PPS remap set, letting one chip drive a 320x240 segment LCD while scanning a keypad and a resistive touch panel via the CTMU. Compared with discrete MCU + LCD-driver designs, this part reduces BOM cost by 30-40% and PCB area by 25%, while the PIC24F core delivers 16 MIPS throughput to refresh even a busy display without flicker.
推荐
Capacitive Touch Control for White Goods
The integrated Charge Time Measurement Unit (CTMU) and Configurable Logic Cells (CLC) allow the PIC24FJ128GA610T-I/BG to implement up to 32 capacitive touch buttons plus slider/wheel patterns without an external touch IC. Operating from 2.0V to 3.6V and rated -40 C to +85 C industrial, the part survives the kitchen/laundry environment while running user-interface firmware directly out of 128 KB Flash. The CTMU converts capacitance to a digital count, while CLC offloads wake-on-touch logic, reducing average power consumption to microamps.
推荐
USB-Enabled Sensor Hub / Data Logger
When paired with an external USB transceiver, the PIC24FJ128GA610T-I/BG can serve as a USB device-class sensor hub thanks to its 32 KB SRAM, DMA-driven UART/SPI/I2C set, and 128 KB Flash to hold both application firmware and the USB stack. The 121-ball TFBGA exposes enough I/O to attach a multi-axis IMU, environmental sensor, and SD card simultaneously. Note that the GA610 variant lacks an integrated USB peripheral; for true single-chip USB drop-in, choose the GB610 variant in the same package.
推荐
Battery-Backed Metering / Smart Energy
The PIC24FJ128GA610T-I/BG's low-power Sleep mode (sub-10 uA), integrated RTCC with backup power, and 10-bit ADC with up to 32 inputs make it well suited for electricity/gas/water metering endpoints that wake periodically to log consumption. The 32 KB SRAM buffers time-stamped measurements between transmissions, while the 16 MIPS core runs AES-128 encryption for security. The 2.0V minimum supply lets the part run directly from a single 3V lithium primary cell with no boost regulator.
推荐
Medical Point-of-Care Diagnostic Reader
The PIC24FJ128GA610T-I/BG's integrated 10-bit ADC, DMA, and 32 KB SRAM allow it to manage colorimetric and electrochemical sensor readouts in handheld diagnostic instruments (e.g., glucose meters, lateral-flow readers). The CTMU handles temperature-compensated timing of enzymatic reactions, while the LCD driver displays patient results directly. Medical designs benefit from the part's wide operating voltage and industrial temperature rating for reliable readings across clinical environments.
推荐
Automotive Body and HVAC Control Module
Although the standard PIC24FJ128GA610T-I/BG is industrial-grade (-40 C to +85 C), the pin-compatible PIC24FJ128GA610-E/BG extends the temperature range to -40 C to +125 C, qualifying it for non-safety automotive body, HVAC, and lighting control modules. The 121-ball TFBGA exposes ample PWM channels for fan/blower speed control, while the RTCC supports scheduled climate routines. For AEC-Q100-qualified automotive variants, Microchip offers the dsPIC33 and PIC32MK families with the same 16-bit performance class.

关键差异点

- Same BG footprint as the 1024 KB upgrade parts, enabling memory-scalable BOM （对比 PIC24FJ1024GA610-I/BG)
- Pin-compatible USB drop-in exists within the same Microchip family （对比 PIC24FJ1024GB610-I/BG)
设计说明
The 121-ball TFBGA uses 0.8 mm ball pitch on a 10x10 mm body. Use microvia-in-pad on a 4-layer (or thicker) stack-up for clean fan-out; dog-bone fan-out through standard vias is unreliable on 0.8 mm pitch. Place a continuous ground plane on layer 2 directly under the BGA to provide a low-impedance reference and thermal path. Estimated: with 0.5 oz copper on outer layers and 1 oz on inner, a single 121-BGA part dissipates up to ~1 W without an explicit heatsink on the back side.
Place one 100 nF X7R 0402 decoupling capacitor as close as possible to every VDD/VSS pair on the BGA (typically one cap per corner quad plus one per interior rail). Add a single bulk 4.7 uF to 10 uF ceramic or tantalum within 5 mm of the regulator. The PIC24FJ core enters low-power Sleep mode that retains RAM; ensure the RTCC backup domain is supplied even when the main rail is removed, by routing VBAT from a coin cell through a Schottky OR-ing diode to the RTCC pin.
Do not assume 'T' suffix parts and non-T suffix parts have different electrical specs - the 'T' only changes shipping carrier (tape-and-reel vs tray). Be aware that the PIC24FJ128GA610 does NOT include a USB peripheral; if you need USB OTG, step to the GB610 family in the same package. When migrating to PIC24FJ1024GA610/GB610, review your linker map because Flash bank boundaries change - existing IVT addresses and EEPROM emulation may need relocation.
合规信息
RoHS and REACH compliant per Microchip product page. Standard -I (Industrial) parts are NOT AEC-Q100 qualified; automotive applications must use the -E (extended) grade parts or a different AEC-Q100-qualified family such as dsPIC33 or PIC32MK.
