PIC24FJ64GA410T-I/PT Overview
A 16-bit microcontroller (MCU) is a single-chip computer that uses a 16-bit data path, instruction word, and register file, sitting hierarchically between 8-bit MCUs and 32-bit ARM Cortex-M parts. PIC24F devices use a modified Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and data access for higher throughput. The 'FJ' family adds segmented LCD support and eXtreme Low Power sleep modes, while the 'GA410' subgroup integrates an AES/SHA crypto accelerator and rich analog peripherals.
Key features include 64 KB (22K x 24) self-programmable Flash, 8 KB SRAM, integrated segmented LCD driver supporting up to 128 segments, an AES/SHA crypto engine, a 12-bit A/D converter with up to 16 channels, multiple UART/SPI/I2C peripherals, and nanoWatt XLP technology that drops quiescent current below 1 µA in deep sleep. The part is qualified for -40C to +85C industrial operation.
The PIC24FJ64GA410 architecture combines a 16-bit modified-Harvard CPU core, hardware crypto acceleration, and segmented LCD control on a single die, allowing secure token generation and direct glass LCD driving without an external driver. XLP technology uses dynamic clock gating, deep sleep modes with RAM preservation, and a real-time clock calendar running from a 32 kHz source to deliver multi-year battery life in metering and medical applications.
Typical applications include secure payment terminals, IoT sensor nodes with LCD displays, portable medical monitors, electronic utility meters, and secure authentication tokens. Designers choose this part when they need integrated crypto plus LCD driving in a single low-power MCU.
When designing with this MCU, allocate sufficient PCB area for the segmented LCD routing and follow Microchip AN1365 for proper bias generation. The crypto engine uses a hardware RNG; consult the family datasheet for key-storage best practices.

Typical Applications
PIC24FJ64GA410T-I/PT is suitable for 6 applications: Secure Payment Terminal, Portable Medical Monitor, Electronic Utility Meter, IoT Sensor Node with LCD, Secure Authentication Token, Industrial HMI Control Panel.
Secure Payment Terminal
The PIC24FJ64GA410T-I/PT fits secure payment terminals because its integrated AES/SHA hardware crypto engine and hardware RNG eliminate the need for an external secure element, reducing BOM and PCB area. With 64 KB Flash and 8 KB SRAM, it runs EMV transaction stacks while AES-128 accelerates PIN encryption under 50 ms. The 100-pin TQFP provides enough I/O for keypad, LCD, and contactless reader interfaces, and nanoWatt XLP keeps sleep current under 1 µA for multi-year battery life.
Recommended
Portable Medical Monitor
For portable medical monitors such as glucose meters and pulse oximeters, the PIC24FJ64GA410T-I/PT provides the segmented LCD driver needed for direct glass display driving plus the ADC and XLP low-power modes required for battery operation. The 12-bit ADC supports accurate sensor readings, while deep-sleep retention preserves measurement history across battery swaps. The 100-pin TQFP gives enough GPIO for keypad, sensor I2C, and the LCD bias network in a single chip.
Recommended
Electronic Utility Meter
The PIC24FJ64GA410T-I/PT is well-suited to single-phase electronic utility meters because its segmented LCD driver supports the multi-digit display while its 32 MHz PIC24F core handles metrology calculations and tamper detection. The hardware AES engine secures wireless M-Bus or LoRaWAN communication, and XLP deep-sleep with RTC keeps average current below 10 µA so meters last 10+ years on a single lithium battery. Industrial -40C to +85C rating covers outdoor meter enclosures.
Recommended
IoT Sensor Node with LCD
For IoT sensor nodes that display readings locally on a segmented LCD, the PIC24FJ64GA410T-I/PT integrates the LCD driver and crypto engine on a single die, eliminating two external ICs. The 16-bit core handles sensor fusion and AES-secured MQTT/CoAP over SPI to a wireless module, while XLP sleep modes with RAM retention allow wake-on-interrupt operation at average currents below 5 µA. The 100-pin TQFP gives designers room to add RS-485 or CAN for industrial IoT nodes.
Recommended
Secure Authentication Token
For hardware authentication tokens (FIDO/security keys), the PIC24FJ64GA410T-I/PT's hardware AES/SHA engine and RNG perform all cryptographic operations in silicon, making secret extraction difficult. Its 32 MHz performance keeps USB HID transaction latency under 50 ms, and XLP modes allow the token to idle for months on a coin cell. The 100-pin TQFP supports tactile switch inputs, status LED, and USB-C CC logic via spare GPIO.
Recommended
Industrial HMI Control Panel
For industrial HMI panels with a segmented LCD and physical buttons, the PIC24FJ64GA410T-I/PT offers the LCD driver, 16-bit performance, and 100-pin GPIO count needed for menu navigation and process control. The AES engine secures fieldbus data on Modbus-TCP or PROFINET gateways, and -40C to +85C operation tolerates factory-floor temperatures. NanoWatt XLP plus RTC enables scheduled sleep cycles that save power when the panel is idle.

Design Notes
Estimated: at 32 MHz active with all peripherals on, the PIC24FJ64GA410T-I/PT draws roughly 15 mA at 3.3V (~50 mW). In deep-sleep with RTC running, XLP modes drop this below 1 µA. For battery-life calculations, assume an average current of (active_duty * 15 mA) + (sleep_duty * 1 µA); a 1% duty cycle yields ~150 µA average. Place a 10 µF bulk + 0.1 µF decoupling cap pair within 5 mm of each VDD pin.
Route the segmented LCD SEG and COM traces with care: keep them away from high-frequency digital lines, avoid 90-degree bends, and use a guard ground trace between SEG/COM and noisy signals. The PIC24FJ64GA410T-I/PT LCD bias generation requires external capacitors on the VLCAP pins (typically 0.1 µF); omit these only if you are using an external LCD bias supply. Follow the LCD pad and trace spacing rules in the Microchip AN1365 application note.
Do not assume that the AES/SHA crypto engine on the PIC24FJ64GA410T-I/PT is automatically secure; keys must be stored in designated Flash regions with read-protect bits set, and the RNG must be seeded according to the family datasheet. Using software delays in crypto routines without consulting section 32 of the datasheet can leak timing information. Always erase the Flash key region before mass production to avoid test-key leakage.
