The Microchip Technology PIC24FJ128DA206-I/PT is a 16-bit PIC24F-family Flash microcontroller with an integrated graphics controller, USB On-The-Go (OTG), 128 KB (43K x 24) of program Flash, and 96 KB of RAM, packaged in a 64-pin TQFP (10 x 10 mm) with industrial -40C to +85C temperature rating. It executes instructions at 32 MHz (16 MIPS) from an internal oscillator, providing 52 general-purpose I/O pins and a wide 2.2 V to 3.6 V operating range suited to USB and graphics subsystems. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), and peripherals such as ADC, timers, communication controllers, and I/O. The PIC24F is Microchip's 16-bit modified-Harvard MCU family, positioned between 8-bit PIC16/PIC18 and 32-bit PIC32MX parts; it scales up by adding larger memories, USB, and richer peripherals while retaining PIC assembly compatibility. The 'DA' sub-family adds an LCD/graphics display controller capable of driving displays up to 4.3" WQVGA at 480 x 272 resolution, and the 'F' core carries eXtreme Low Power (XLP) technology for battery-friendly designs. Key features of the PIC24FJ128DA206 include an integrated full-speed USB 2.0 OTG controller with on-chip transceiver, a 3-bit graphical display controller with hardware acceleration, up to 96 KB SRAM for frame buffering, an 8-channel 10-bit ADC, multiple UART/SPI/I2C peripherals, and CTMU for capacitive touch sensing. The 64-pin TQFP package exposes all major peripherals while keeping the footprint compact for embedded HMI boards. Architecturally, the PIC24F core uses a 16-bit modified-Harvard bus with separate program and data paths, a 24-bit instruction word, and 16 working registers. The internal 8 MHz Fast RC oscillator (with PLL up to 32 MHz) eliminates external crystals in many designs. The graphics pipeline offloads pixel rendering from the CPU, and the USB OTG stack supports both host and device roles for product-flexibility. Typical applications include low-cost color graphical HMI panels (appliance control, thermostats, medical instrument UIs), USB peripherals and embedded hosts (mass storage, HID, CDC), battery-powered portable instrumentation with touch sensing, industrial control panels requiring graphical diagnostics, and consumer products needing a USB charging or data interface. The graphics + USB combination is the strongest value proposition versus generic PIC24F parts. When designing with this part, plan the PCB for a 4-layer stack-up so the TQFP-64 decoupling loop is short and the USB DP/DM traces are 90-character, length-matched, and impedance-controlled near 90 ohms differential. The internal oscillator is usually sufficient, but add a footprint for an optional crystal if the application needs tight USB clock accuracy.

PIC24FJ128GA202-I/SP - 16-bit 32MHz 128KB Flash MCU | Microchip

The Microchip Technology PIC24FJ128GA202-I/SP is a 16-bit microcontroller from the PIC24F family with eXtreme Low Power (XLP) technology, an integrated crypto module, and 128KB Flash program memory in a 28-pin SPDIP through-hole package. It operates up to 32MHz delivering 16 MIPS at 3.3V and includes 8KB SRAM plus peripheral features targeted at low-power embedded designs. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program and data memory, and a rich set of on-chip peripherals such as timers, communication interfaces, ADC/DAC modules, and GPIO into a single chip. The PIC24FJ family belongs to the modified Harvard RISC architecture family and uses 16-bit instruction words with up to 24-bit opcode extensions, balancing deterministic real-time performance with low active and sleep currents. PIC24F devices are positioned within Microchip's portfolio between 8-bit PIC16/PIC18 MCUs (cost-optimized, simpler) and dsPIC/PIC32 (32-bit, higher MIPS) — useful when code density, numeric range, and low energy are all required. Key features of the PIC24FJ128GA202-I/SP include 128KB Flash, 8KB SRAM, an integrated crypto module for secure data handling, multiple serial interfaces (UART, SPI, I2C), 10-bit ADC, capture/compare/PWM modules, and deep-sleep current in the microamp range enabled by XLP technology. The integrated crypto engine accelerates AES-like operations without external companion ICs, reducing BOM and PCB area. Architecturally, the device uses a 16-bit modified Harvard core with a 7-channel DMA controller, hardware multiplier, and multiple clock sources including a 32kHz low-power oscillator and an 8MHz internal RC. The crypto module provides a hardware-accelerated block for encryption/decryption, and the eXtreme Low Power design lowers run and idle currents compared with prior PIC24 generations. Typical applications include secure IoT edge nodes, battery-powered sensor hubs, low-power wireless gateways, secure access control modules, smart metering, and industrial HMI panels. The combination of XLP current profiles and on-chip crypto is particularly attractive for devices that must sleep most of the time and encrypt rare bursts of telemetry. When designing with this MCU, plan oscillator start-up timing and use the XLP deep-sleep retention mode wherever possible to extend battery life. Validate AES throughput against your protocol's session rate, and ensure the SPDIP-28 footprint provides sufficient thermal headroom at the target ambient.

PIC24FJ128GA202-I/SS

PIC24FJ128GA202-I/SS - 16-bit 32MHz 128KB Flash MCU | Microchip

The Microchip PIC24FJ128GA202-I/SS is a 16-bit PIC24F microcontroller with 128 KB Flash, 8 KB RAM, an integrated hardware crypto engine, and eXtreme Low Power (XLP) technology, packaged in a 28-pin SSOP. It runs at up to 32 MHz (16 MIPS) and operates from 2.0 V to 3.6 V, making it suitable for battery-powered embedded applications that demand both security and low energy consumption. A 16-bit flash microcontroller is a microprocessor that fetches and executes 16-bit-wide instructions from non-volatile Flash memory, providing higher code density and richer peripherals than 8-bit MCUs while remaining easier to program than 32-bit cores. Within the broader semiconductor taxonomy, the PIC24FJ128GA202 sits in the PIC24F XLP subfamily, which extends the PIC microcontroller line -> PIC24F family -> 16-bit MCU -> microcontroller (MCU) -> embedded processing IC -> semiconductor. Its integrated crypto engine with ISO 7816 support makes it especially attractive for contactless smart-card, secure-element, and authentication endpoints that previously required a companion secure IC. Key features include 128 KB self-programmable Flash with ECC, 8 KB SRAM, hardware AES/SHA/DES/Triple-DES/RSA/ECC acceleration (Microchip proprietary crypto library), four 16-bit timers, two UART/I2C/SPI modules, a 10/12-bit ADC with up to 16 channels, five 16-bit PWM/CCP/SCCP channels, a Real-Time Clock and Calendar (RTCC) with calendar mode, and an integrated 32 kHz low-power oscillator. The XLP nanoWatt technology delivers standby currents below 20 nA (typical) in deep-sleep modes, while the 32 MHz internal oscillator eliminates an external crystal in cost-sensitive designs. Typical applications include secure contactless payment terminals, IoT sensor nodes with TLS acceleration, smart energy meters with cryptographic signing, battery-powered medical wearables, and ISO 7816 smart-card interface boards. In each case the part combines the right mix of secure-element hardware and eXtreme Low Power run/sleep modes to extend battery life while offloading cryptographic primitives from the main CPU. When designing with this part, plan for a decoupling network of 100 nF + 4.7 uF ceramic caps on VDD/AVDD with traces kept short to the SSOP body. Use the 32 kHz SOSC crystal only if RTCC calendar drift below ±5 ppm is required; otherwise the internal LPRC oscillator is sufficient for low-power timekeeping.
