PIC24FJ64GB406T-I/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals such as timers, communication controllers, ADCs, and I/O pins. The PIC24FJ64GB406 belongs to the 16-bit PIC24F sub-family, which sits hierarchically above 8-bit PIC MCUs and below 32-bit ARM Cortex-M devices, offering higher code density and richer peripherals while retaining low power consumption. This makes the part especially suitable for battery-powered embedded products that need more compute than 8-bit cores can offer but cannot justify a Cortex-M0 design cost.
Key features include 64 KB Flash (22K x 24 instruction words), 8 KB SRAM, integrated USB 2.0 full-speed OTG with PHY, hardware AES/SHA crypto engine, up to 52 GPIO pins, a segmented LCD driver supporting up to 192 segments, multiple UART/SPI/I2C interfaces, a 10-bit ADC, and ultra-low-power sleep modes drawing less than 1 uA with RTCC retention. The wide 2.0 V to 3.6 V operating range lets the device run directly from a single Li-ion cell or two AA cells.
Typical applications include secure IoT sensor nodes, USB HID peripherals, smart meters with LCD displays, electronic shelf labels, medical portable monitors, and secure payment terminals where the on-chip hardware crypto accelerator offloads AES/SHA workloads from the CPU. The combination of USB OTG, LCD, and crypto in a single die reduces both BOM cost and PCB area.
When designing with this device, ensure the 64-pin TQFP land pattern matches the variant ordered. The trailing "/PT" suffix confirms the 10x10 mm TQFP-64 package; the related "/MR" suffix denotes a smaller 64-pin QFN package and is therefore NOT drop-in compatible. For long battery life, leverage the deep-sleep and Retention modes documented in the Microchip XLP family datasheet rather than relying on Idle mode.

Applications typiques
PIC24FJ64GB406T-I/PT convient pour 6 applications: Secure USB HID Peripherals, Battery-Powered IoT Sensor Nodes, Smart Meters with LCD Display, Medical Portable Monitors, Electronic Shelf Labels (ESL), Secure Payment Terminals.
Secure USB HID Peripherals
The PIC24FJ64GB406T-I/PT is a strong match for USB HID peripherals that require hardware-accelerated cryptography because it integrates USB 2.0 full-speed OTG with on-chip PHY and an AES/SHA crypto engine on the same die. The 32 MHz 16 MIPS core handles HID class drivers plus crypto offload without saturating, while 64 KB Flash and 8 KB RAM comfortably hold USB stacks, HID report handlers, and AES routines. Compared to a discrete USB MCU + external crypto chip, this single-chip solution cuts BOM cost by roughly 30% and PCB area by half. Designers typically route D+/D- to the USB connector with 22 ohm series resistors and tie VBUS to the sense pin for OTG negotiation.
Recommandé
Battery-Powered IoT Sensor Nodes
For battery-powered IoT sensor nodes that need secure data uplink, the PIC24FJ64GB406T-I/PT offers less than 1 uA deep-sleep current with RTCC and RAM retention, enabling multi-year coin-cell operation. Its 10-bit ADC reads battery voltage and analog sensor signals, while the hardware crypto engine secures MQTT/TLS payloads on demand. The 2.0-3.6 V supply range supports direct Li-ion or 2x AA operation without a boost converter. Compared to an 8-bit PIC16 baseline, the 16-bit core delivers 4x faster arithmetic per mA, extending battery life while supporting richer sensor processing and TLS 1.2 handshake flows.
Recommandé
Smart Meters with LCD Display
The PIC24FJ64GB406T-I/PT is purpose-built for smart meter applications thanks to its integrated segmented LCD driver supporting up to 192 segments, eliminating the need for an external LCD controller. Combined with the on-chip 10-bit ADC for voltage/current sensing, 52 GPIO for pulse counters, and UART for AMR/AMI communications, the part provides a single-chip metering solution. The XLP family's deep-sleep mode (less than 1 uA) preserves meter autonomy for over 10 years on a single lithium battery, while AES-128 hardware encryption secures consumption data against tampering.
Recommandé
Medical Portable Monitors
The PIC24FJ64GB406T-I/PT fits portable medical devices such as pulse oximeters and handheld glucose meters, where its hardware crypto engine protects patient health information (PHI) per HIPAA requirements. The 32 MHz 16 MIPS core drives LCD segmented displays directly, runs sensor DSP, and handles BLE/USB data export with encryption, all from a single chip. Operating from 2.0-3.6 V with sub-uA sleep current extends battery life to weeks on a single coin cell. The wide -40C to +85C industrial temperature range suits home healthcare and clinical environments.
Recommandé
Electronic Shelf Labels (ESL)
The PIC24FJ64GB406T-I/PT supports electronic shelf label designs requiring wireless or NFC updates plus a low-power segmented LCD, where its on-chip LCD driver and XLP sleep mode (<1 uA) are key. With 64 KB Flash and 8 KB RAM, it can manage ESL communication stacks and pricing tables for thousands of items per gateway, while the integrated crypto engine authenticates firmware updates to prevent spoofing. The wide supply range and sub-uA standby enable multi-year battery life on CR2032 cells, critical for retail shelf deployments.
Recommandé
Secure Payment Terminals
The PIC24FJ64GB406T-I/PT is a drop-in fit for low-cost secure payment terminals where PCI PTS compliance demands hardware AES/SHA acceleration. Its hardware crypto engine executes AES-128 encryption on PIN blocks in a single cycle, reducing code side-channel leakage and meeting PTS requirements. USB OTG enables connectivity to mobile POS hosts while the segmented LCD driver supports 16x4 alphanumeric customer displays. Compared to software-only crypto on a 32-bit ARM part, the dedicated engine halves transaction latency and reduces overall BOM cost by approximately 25%.

Notes de conception
Decouple VDD/VSS pairs with 100 nF ceramic capacitors placed within 3 mm of each pin pair. According to Microchip's PIC24F XLP family datasheet section on hardware design guidelines, a bulk 4.7 uF tantalum or ceramic near the MCU plus one ferrite bead on VDD improves noise immunity when USB OTG or LCD driver is active. AVDD/AVSS should be tied to VDD/VSS but with their own RC filter (10 ohm + 100 nF) for clean ADC reference operation.
Do not confuse the '/PT' TQFP-64 package suffix with '/MR' QFN-64; they require different PCB footprints and are NOT drop-in compatible. Estimated: at 32 MHz operation with all peripherals active, core current is approximately 15 mA and USB OTG adds up to 8 mA. Ensure VBUS sensing pin is properly biased when designing OTG host mode or USB enumeration will fail. Always configure the oscillator PLL with the correct FPLL settings or the USB 48 MHz clock tolerance will exceed the +/- 0.25% requirement.
Estimated: in the 64-pin TQFP-64 package (10x10 mm) with theta_JA of approximately 50 C/W on a standard 2-layer JEDEC test board, the PIC24FJ64GB406T-I/PT can dissipate up to 2 W within industrial temperature limits before requiring additional copper pours. For USB OTG host applications driving current through VBUSON, recommend a 4-layer PCB with a dedicated ground plane and at least 1 square inch of copper on VDD traces to keep junction temperature below 125C.
Route USB D+ and D- traces as a 90 ohm differential pair with trace length matching within 2 mm and keep total length under 50 mm. Place the crystal oscillator (typically 8 MHz or 12 MHz fundamental) within 5 mm of the OSCI/OSCO pins and guard the traces with a ground ring to prevent noise injection into the PLL. For segmented LCD applications, route LCD segment/com pins on the opposite side of switching signals to minimize crosstalk and improve contrast.
