PIC24FJ128GA406T-I/PT

PIC24FJ128GA406T-I/PT - 16-bit MCU 128KB Flash XLP LCD | Microchip

The Microchip Technology PIC24FJ128GA406T-I/PT is a 16-bit PIC24F microcontroller from the eXtreme Low Power (XLP) family, featuring 128 KB of Flash program memory, 16 KB of RAM, and an integrated segmented LCD controller, packaged in a 64-pin TQFP (10x10 mm) and supplied on Tape & Reel. It executes instructions at up to 16 MIPS from a 32 MHz internal oscillator, drawing nanoWatt XLP sleep currents for battery-powered designs. According to the Microchip product page, the device is built around a modified Harvard architecture with a hardware crypto engine, segmented LCD driver, multiple UART/SPI/I2C peripherals, a 10/12-bit ADC, and a 16-bit Parallel Master Port for external bus expansion. What is a 16-bit PIC24F microcontroller? It is a class of mid-performance, 16-bit RISC MCU from Microchip that sits between the 8-bit PIC16/PIC18 family and the 32-bit PIC32MX/dsPIC family, balancing code density, peripheral integration, and ultra-low power for cost-sensitive embedded products. The PIC24F sub-family extends this with nanoWatt XLP technology that enables deep-sleep currents below 1 microamp, segmented LCD drivers that eliminate external LCD bias components, and integrated crypto accelerators for secure connectivity in IoT and metering applications. Key features of the PIC24FJ128GA406T-I/PT include 128 KB Flash (43K x 24 instructions), 16 KB SRAM, 4 KB EEPROM, 85 I/O pins (subject to package), an integrated segmented LCD controller supporting up to 132 segments, a 10-bit ADC up to 500 ksps, USB 2.0 full-speed OTG, a hardware crypto engine, and a Parallel Master Port. Operating voltage spans 2.0 V to 3.6 V, and the device supports industrial temperature ranges of -40C to +85C. The 64-pin TQFP provides a low-profile surface-mount footprint suitable for compact consumer, industrial, and metering designs. The PIC24FJ128GA406T-I/PT architecture combines a 16-bit modified Harvard core with 24-bit instructions, hardware multiply/divide, a 17 x 17-bit single-cycle multiplier, and a 32-bit barrel shifter, delivering deterministic interrupt latency and high code density. The eXtreme Low Power technology uses multiple power domains, deep-sleep modes with RAM retention, and a Real-Time Clock/Calendar (RTCC) running from a dedicated 32 kHz crystal, allowing current consumption below 1 microamp in sleep while maintaining timing functions and external wake events. Typical applications include IoT sensor nodes and wireless modules, portable medical devices and health monitors, low-power industrial HMI with LCD displays, smart metering (electricity/gas/water), home appliances with segmented LCD user interfaces, and secure connected devices using the integrated crypto engine. The wide peripheral set, large RAM, and LCD controller make it especially well suited for human-machine interface applications where the LCD eliminates the need for a separate graphics controller. When designing with this part, ensure that the decoupling strategy includes a 100 nF ceramic capacitor within 2 mm of each VDD/VSS pair, route the 32 kHz crystal traces short and symmetric, and configure the unused I/O pins as outputs low to minimise current leakage. The Parallel Master Port pins (PMALL/PMP) can be repurposed as general-purpose I/O if external bus expansion is not needed, freeing them for application use.

PIC24FJ128GA410-I/PT - 128KB Flash 16-bit XLP MCU | Microchip

The Microchip Technology PIC24FJ128GA410-I/PT is a 16-bit PIC microcontroller built on the eXtreme Low Power (XLP) architecture with an integrated crypto module, 128KB of Flash program memory, 16KB of RAM, and a segmented LCD driver, all housed in a 100-pin TQFP (PT) package. The device runs up to 32 MHz delivering 16 MIPS at 3.3V and operates across a 2.0V-3.6V supply range, making it well suited to battery-powered and energy-harvesting designs. On-chip peripherals include a 10-bit and 12-bit ADC, multiple UART/SPI/I2C, comparators, RTCC, and the segmented LCD controller capable of driving up to 480 segments. A 16-bit MCU is a microcontroller whose data path and registers are 16 bits wide, offering a balance between the simplicity of 8-bit MCUs and the throughput of 32-bit parts. The PIC24F family sits in the microcontroller -> embedded controller -> semiconductor hierarchy and is widely adopted where low power, deterministic interrupt response, and rich analog integration are required. The XLP technology in the PIC24FJ128GA410 adds deep-sleep currents below 1 uA with retention, real-time clock, and LCD bias generation all active. Key features of the PIC24FJ128GA410 include hardware crypto acceleration for AES/SHA, dual-partition Flash with live update support, CTMU for capacitive touch and slope-compensation, a segmented LCD driver, and a Parallel Master Port (PMP) for external bus expansion. The device integrates CTMU, DMA, and an 8-channel hardware crypto engine that offloads authentication, encryption, and hashing from the CPU, freeing cycles for application logic. The PIC24FJ128GA410 uses a modified Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and data access for sustained 16 MIPS throughput. The dual-partition Flash enables fail-safe firmware updates - one bank runs while the other is reprogrammed - and the eXtreme Low Power technology, combined with peripheral modules that can run in sleep, makes the part attractive for medical, metering, and secure IoT edge nodes. Typical applications include secure IoT edge nodes, smart energy meters with LCD readout, medical devices such as glucose meters, white goods, point-of-sale terminals, home automation HMIs, and industrial control panels. The integrated LCD driver eliminates an external LCD bias generator, and the crypto module addresses designers who need authenticated firmware and secure communication without an external secure element. When designing with this device, allocate PCB area for the segmented LCD glass routing early - the LCD pin assignment constrains the PCB layout more than the digital peripherals. Also note that the I/PT suffix denotes the industrial temperature grade (-40C to +85C), 100-pin TQFP, tray packaging.
