PIC24FJ256GA110-I/PT

PIC24FJ256GA110-I/PT - 32MHz 256KB Flash 16-bit MCU | Microchip

The Microchip Technology PIC24FJ256GA110-I/PT is a 16-bit PIC24F microcontroller running at up to 32 MHz (16 MIPS) with 256 KB of Flash program memory (85.5K x 24 words) and 16 KB of RAM, packaged in a 100-pin TQFP (12x12 mm, PT suffix). It belongs to the PIC24FJ eXtreme Low Power family and integrates Peripheral Pin Select (PPS) for flexible signal mapping, hardware multiplier, DMA controller, and 85 general-purpose I/O pins. Operating voltage spans 2.0 V to 3.6 V across the industrial -40C to +85C temperature range. A 16-bit microcontroller (MCU) is a class of embedded processor with a 16-bit data path and 16-bit instruction width that balances the throughput of 32-bit devices with the code density and cost of 8-bit devices. Within the broader taxonomy: MCU -> 16-bit MCU -> PIC24 family -> PIC24F sub-family (Flash, low-power). PIC24F parts use a modified Harvard architecture with a 24-bit instruction word, making them well-suited to mixed-signal control applications that exceed 8-bit capability but do not require a DSP. Key features include 256 KB self-programmable Flash with ECC, 16 KB SRAM, three 16-bit timers plus five 16-bit Timer/Counter modules, four UART, three SPI, three I2C, an 8-channel hardware DMA, a 10/12-bit ADC with up to 500 ksps, two analog comparators, and a Real-Time Clock Calendar (RTCC) with less than 100 nA standby current. The hardware multiplier performs 16x16-bit signed operations in a single cycle. Integrated peripherals include a Parallel Master Port (PMP) for graphics and a 16-bit PMP for external memory/display interfaces. Architecturally the PIC24FJ256GA110 uses a 5-stage pipeline, a 24-bit instruction bus, dual-port SRAM, and a Peripheral Pin Select engine that remaps digital peripherals to any of the 85 I/O pins at runtime. eXtreme Low Power (XLP) technology, deep-sleep gating of unused peripherals, and an on-chip LDO regulator keep active current in the low single-digit mA range and standby current below 100 nA. The CTMU peripheral provides touch sensing and time-of-flight measurement. Typical applications include low-power connected sensors, industrial HMI panels, USB/HID bridges, point-of-sale terminals, automotive body controllers, portable medical instrumentation, and graphics/text TFT displays driven by the integrated PMP interface. The 256 KB Flash and 16 KB RAM are well sized for IPv4/IPv6 stacks, USB device class drivers, and small RTOS kernels such as FreeRTOS or Micrium. When designing with this device, place a 10 uF + 0.1 uF bulk-decoupling pair near VDD/AVDD pins and ensure the PPS mapping is locked in the configuration bits before runtime, since PPS registers are write-protected after the first write. Configure the integrated LDO regulator mode carefully when using an external 3.3 V rail to avoid contention. Unused pins should be configured as outputs low or as inputs with the internal pull-up enabled.

It runs up to 32 MHz delivering 16 MIPS of CPU throughput at 3.3 V, and operates across a 2.0 V to 3.6 V supply range. On-chip peripherals include a segmented LCD controller, an integrated crypto module with code-guard security, multiple 10-bit and 12-bit ADCs, and 53 general-purpose I/O pins supporting numerous serial protocols. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and peripherals such as ADCs, timers, communication interfaces, and I/O controllers. The 16-bit class sits between 8-bit MCUs (typically used for simple control tasks) and 32-bit ARM Cortex-M parts (used for high-performance DSP and connectivity), offering a balanced mix of computational throughput, deterministic interrupt response, and low power consumption. The PIC24F family uses Microchip's modified Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and data access. Key features of the PIC24FJ256GA406 include the integrated segmented LCD driver (up to 64 segments), which removes the need for an external LCD controller in display-based products, and the hardware crypto engine with intermediate code-guard security that protects intellectual property in deployed firmware. The XLP technology delivers deep-sleep currents in the nanoampere range and multiple power-saving modes such as Sleep, Idle, and Doze, enabling years of operation from a single coin cell. The 53 I/O pins are 5 V tolerant on many ports, allowing direct interfacing with legacy 5 V logic. Two UART/SPI/I2C peripherals, up to five 16-bit timers, and configurable remappable peripherals provide extensive design flexibility. Architecturally, the device pairs the PIC24F modified Harvard CPU core with a wide peripheral set tuned for low-power embedded designs. The dual-partition Flash supports safe in-field firmware updates (one partition runs while the other is reprogrammed), and the on-chip 12-bit ADC reaches 500 ksps for sensor sampling. Hardware DSP extensions accelerate multiply-accumulate routines for sensor fusion or audio preprocessing. The combination of XLP power management, integrated crypto, segmented LCD, and dual-partition Flash is what differentiates this part from generic 16-bit MCUs without security or display support.

PIC24FJ256GA406-I/PT

PIC24FJ256GA406-I/PT - 256KB Flash 16-bit XLP MCU | Microchip

The Microchip Technology PIC24FJ256GA406-I/PT is a 16-bit microcontroller from the PIC® XLP™ 24F family featuring 256 KB Flash, 16 KB RAM, and a 64-pin TQFP (10x10 mm) industrial-temperature package. It integrates an enhanced crypto module with AES-128, segmented LCD driver, and eXtreme Low Power (XLP) technology, delivering up to 32 MHz / 16 MIPS performance at 3.3 V. According to the Microchip PIC24FJ256GA406 datasheet, the device combines an integrated AES engine, 24-channel 10-bit ADC, segmented LCD controller with charge pump, and 5 CCP modules alongside USB 2.0 full-speed OTG and multiple UART/SPI/I²C peripherals. What is a 16-bit MCU with XLP? A microcontroller (MCU) is a single-chip computer containing a CPU, memory, and peripherals. The "16-bit" designation indicates the data path width, giving it 2x the data throughput of an 8-bit MCU while remaining simpler and lower-power than 32-bit Cortex-M parts. PIC24F microcontrollers sit in the hierarchy: 16-bit MCU -> PIC24 family -> XLP 24F series -> PIC24FJ256GA406 sub-family. The "XLP" (eXtreme Low Power) branding refers to Microchip's nanoWatt XLP technology that enables deep sleep currents below 1 µA, making these parts ideal for battery-powered and energy-harvesting designs. Key features include the integrated crypto engine with AES-128 and code-guard security, 256 KB self-programmable Flash with ECC, segmented LCD driver supporting up to 100 segments, and on-chip USB 2.0 full-speed OTG. The Peripheral Pin Select (PPS) remapping system allows flexible I/O assignments, while the 24-channel 10-bit ADC and dual analog comparators serve sensor-rich applications. XLP technology provides 9 deep-power-down modes with currents as low as 20 nA in deep sleep, which is critical for wearables and metering. Architecturally, the device uses a Harvard RISC core with modified instruction sets and a 16-element by 16-bit working register array, achieving 16 MIPS at 32 MHz. The 256 KB Flash is dual-partitioned to support live firmware updates, and 16 KB SRAM supports data-intensive segments. Integrated DMA enables peripheral-to-memory transfers without CPU intervention, freeing cycles for application logic. The crypto engine offloads AES encryption tasks, while the segmented LCD controller with integrated charge pump drives resistive LCD glass from a 2.0-3.6 V supply. Typical applications include industrial metering (electricity, gas, water), portable medical devices, secure IoT edge nodes with over-the-air firmware updates, building automation panels with LCD keypads, and USB-based data loggers. The wide 2.0 V to 3.6 V operating range and 1.8 V minimum Flash programming voltage support single-cell Li-ion and two-AA battery topologies. When designing with this part, allocate PCB area for an external 12 MHz or 16 MHz crystal and the segmented LCD bias capacitors; the integrated charge pump simplifies low-temperature LCD contrast but requires proper bulk decoupling. The PPS system should be configured early in firmware since remapping after peripheral initialization can cause transient glitches. For low-power modes, verify the brown-out reset threshold matches the battery discharge curve to avoid spurious resets in deep sleep.

PIC® 24F devices are built on a 16-bit modified Harvard architecture with DSP instruction support, providing a balance between deterministic real-time control and signal-processing throughput. What is a 16-bit microcontroller? A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory (Flash), volatile working memory (RAM), and a rich set of peripherals on one die. 16-bit MCUs occupy the middle ground between 8-bit parts (lowest cost, simplest peripherals) and 32-bit MCUs (highest performance, richest ecosystems); they typically deliver 1 to 2 MIPS per MHz, 16-bit-wide datapaths, and DSP-friendly instructions at clock rates of 16–70 MHz. Hypernyms: microcontroller -> MCU -> embedded processor -> semiconductor. Synonyms used across the industry: MCU, microcontroller, micro-controller, embedded controller. Key features of the PIC24FJ256GA702 family include 256 KB ECC Flash for safer code storage, 16 KB RAM, DMA for offloading data movement, 12-bit 200 ksps ADC, 3 op amps/comparators with programmable biasing, CTMU for capacitive touch, USB/Full-Speed in related variants, and multiple low-power sleep modes via the XLP architecture that drop quiescent current below 1 µA in deep sleep. The PIC24F core also supports a peripheral pin-select (PPS) remapping block on many members, simplifying PCB routing. Technically, the PIC24FJ256GA702 uses Microchip's nanoWatt XLP technology with multiple power-managed Run/Idle/Sleep modes, brown-out reset, watchdog timer, real-time clock calendar, and a flexible 16-bit timer/capture/compare/PWM engine. ECC on Flash improves reliability in harsh environments, while DMA accelerates high-bandwidth peripheral transactions such as ADC double-buffering or UART/SPI looped transfers. Typical applications include low-power IoT sensor nodes, capacitive-touch HMI panels, portable medical monitoring accessories, USB peripherals (related variants), industrial sensor transmitters, and battery-powered metering. For each of these, the combination of large ECC Flash, ample RAM, and XLP quiescent current is the key selection factor. When designing with this part, budget 22 I/O lines (per JLCPCB listing) and confirm peripheral pin-select mappings against the chosen 28-pin SOIC variant to avoid pin-conflict surprises.
