PIC24FJ256GA110T-I/PF - 256KB Flash 16-bit MCU TQFP-100 | Microchip
MPN: PIC24FJ256GA110T-I/PF ✓ نشطPIC24FJ256GA110T-I/PF نظرة عامة
A microcontroller (MCU) is a single-chip computer containing a CPU core, Flash program memory, RAM, and a rich set of peripherals including timers, communication interfaces, and analog blocks. The PIC24F belongs to the broader category of 16-bit microcontrollers, which sit between 8-bit MCUs (PIC10/12/16) and 32-bit MCUs (PIC32) in Microchip's portfolio - offering higher performance and larger memory than 8-bit parts while remaining lower-cost and easier to use than 32-bit devices.
Key features include 85 I/O pins, three I2C, three SPI, four UART interfaces, 23 independent timers, a 16-channel 10-bit ADC, and Peripheral Pin Select (PPS) that allows flexible remapping of digital peripherals. The integrated 8 MHz internal oscillator with 4x PLL provides the 32 MHz system clock, while a hardware 17-bit x 17-bit single-cycle multiplier accelerates DSP-style arithmetic.
Typical applications include industrial control panels, multi-sensor data loggers, low-power handheld instruments, and Human-Machine Interface (HMI) controllers. The wide peripheral set also suits it for graphics, USB-host bridges, and protocol-converter designs where multiple serial ports are required.
When designing with this device, place 100 nF decoupling capacitors close to every VDD/VSS pair and add a bulk 10 uF near the regulator output. Configure unused I/O pins as outputs to minimise sleep current.

التطبيقات النموذجية
PIC24FJ256GA110T-I/PF مناسب لـ 6 التطبيقs: Industrial Control Panel, Multi-Sensor Data Logger, Low-Power Handheld Instrument, HMI / Graphics Controller, Multi-Port Protocol Converter, USB Device / Host Bridge (companion to PIC24FJ256GB110).
Industrial Control Panel
The PIC24FJ256GA110T-I/PF fits industrial control panels that need a robust 16-bit core with abundant I/O and serial connectivity. Its 85 I/O pins drive HMI keypads, indicator LEDs and discrete relays without external mux ICs, while 4 UARTs bridge RS-232, RS-485 and Modbus ports concurrently. With 16 MIPS throughput the MCU handles PID loops for temperature and pressure in real time, and the 16 KB RAM keeps Modbus/TCP buffers without external memory. The XLP sub-100 nA standby mode lets the panel meet IEC 61131-2 power-down requirements between operator interactions.

Multi-Sensor Data Logger
For portable multi-sensor loggers the 256 KB Flash of PIC24FJ256GA110T-I/PF holds months of raw samples plus file-system metadata, while the 16 KB SRAM stages burst reads from the 16-channel 10-bit ADC before compression. Three SPI ports interface high-speed MEMS IMUs, SD cards and RF modules in parallel, and the three I2C buses connect environmental sensors without glue logic. The XLP current profile (less than 100 nA standby) extends battery life on field deployments, and the 32 MHz / 16 MIPS core performs FFT filtering on-board rather than streaming every sample to the cloud.

Low-Power Handheld Instrument
Handheld meters benefit from PIC24FJ256GA110T-I/PF's combination of 16 MIPS throughput and XLP deep-sleep below 100 nA. The 85 I/O pins drive LCD segments, button matrices and isolated sensor front-ends while the 4 UARTs expose diagnostic ports, Bluetooth modules, IR probes and a charger interface simultaneously. Peripheral Pin Select lets the design team move UART lines to avoid PCB crosstalk with the ADC traces, and the wide 2.0-3.6 V supply range lets a single Li-ion cell power the entire instrument.
موصى به
HMI / Graphics Controller
HMI front-ends that drive small TFT or OLED displays choose PIC24FJ256GA110T-I/PF because its 256 KB Flash stores full GUI assets and fonts while PPS routes 3 SPI buses to the panel, touch controller and external memory. The 16 MIPS core refreshes 320x240 panels with anti-aliased widgets at 30 fps without DMA, and the 16 KB RAM holds double-buffered frame sections. Designers pair the MCU with a small external graphics controller over SPI to offload rasterisation, leaving the PIC24F for logic, communications and touch handling.
موصى به
Multi-Port Protocol Converter
Industrial protocol bridges and gateways rely on PIC24FJ256GA110T-I/PF to fan-out between fieldbuses: its 4 UARTs, 3 SPI and 3 I2C ports can be remapped via PPS to expose concurrent RS-232, RS-485, Modbus RTU, SPI sensor links and I2C slave devices. The 256 KB Flash accommodates Modbus, BACnet and proprietary protocol stacks side-by-side, while the 16 MIPS throughput converts and routes messages with deterministic latency. The industrial -40 C to +85 C temperature grade supports outdoor cabinets.

USB Device / Host Bridge (companion to PIC24FJ256GB110)
Although the PIC24FJ256GA110T-I/PF omits the on-chip USB OTG, it is frequently paired with the PIC24FJ256GB110T-I/PF as a co-processor in USB device stacks: the GA variant runs the application code while the GB variant manages USB enumeration and HID/CDC classes. Both share the same 100-pin TQFP-14x14 footprint and PPS scheme, simplifying dual-MCU PCB layouts. Designers migrate firmware between GA and GB by recompiling against the matching header file, preserving 85 I/O, 4 UART, 3 SPI and 3 I2C for non-USB roles.

ملاحظات التصميم
Place one 100 nF decoupling capacitor within 5 mm of every VDD/VSS pin pair on PIC24FJ256GA110T-I/PF, plus a single 10 uF bulk near the regulator output. The ENVREG pin (50) routes the internal 1.8 V regulator; tie a 10 uF low-ESR cap directly to it. Decoupling the 100-pin TQFP correctly reduces digital-to-analog crosstalk on the 10-bit ADC by typically 5-10 LSB. Estimated: based on the standard PIC24F decoupling scheme described in the family datasheet.
Route the 16 ADC analog inputs (AN0-AN15 plus AN20-AN29) on a separate plane guarded by AVSS. Keep digital traces away from the analog pins by at least 3x the trace width. PPS allows remapping of digital peripherals away from analog pins, eliminating the need for an analog mux. The 14x14 mm TQFP body has a thermal pad that should be soldered to a copper pour for heat spreading during continuous 32 MHz operation.
Do not exceed 3.6 V on VDD or AVDD - the PIC24FJ256GA110T-I/PF is a 3.3 V part despite internal 1.8 V regulation. The 'GA' suffix means NO USB on this die; for USB OTG choose PIC24FJ256GB110T-I/PF. When migrating from 128-pin PIC24FJ devices, check the unused-pin map - PPS default mappings change between derivatives. Always issue a BOR (Brown-Out Reset) configuration bit on prototypes.
