The Microchip Technology PIC24FV16KA301-E/SO is a 16-bit Flash microcontroller from the PIC24F XLP (eXtreme Low Power) family, featuring 16KB (5.5K x 24) of Flash program memory, 2KB RAM, and 512B EEPROM, packaged in a 20-pin SOIC (SO) wide-body 300-mil surface-mount package. It operates at 32MHz / 16 MIPS across a 3.3V-5V wide VDD range and ships with the -E (Extended) temperature grade of -40C to +125C, making it well-suited for industrial and harsh-environment designs. The 'FV' prefix in the part number indicates the wide-voltage (1.8V-5.5V) process variant, while the non-FV 'F' variant is 3V-only. A 16-bit microcontroller is an embedded processor that uses a 16-bit data path and instruction word to balance code density, deterministic interrupt latency, and computational throughput for control-oriented tasks. PIC24F parts sit in Microchip's mid-range 16-bit portfolio above the 8-bit PIC16/PIC18 lines and below the dsPIC33/dsPIC35 DSP-capable parts. PIC24F is purpose-tuned for low-power and mixed-signal applications rather than DSP math, and the XLP sub-family adds nanoWatt technology with sub-uA deep-sleep current to compete with MSP430 and STM32L0 in battery-powered end equipment. Key features of the PIC24FV16KA301-E/SO include a 12-bit ADC, CTMU (Charge Time Measurement Unit) for capacitive touch and mTouch sensing, 16 MIPS performance at 32MHz, deep-sleep-aware peripherals such as DSBOR (Deep-Sleep Brown-Out Reset), DSWDT (Deep-Sleep Watchdog Timer), and RTCC (Real-Time Clock Calendar), plus a Peripheral Pin Select (PPS) subsystem for flexible pin mapping. The device integrates a 16-bit timer, 3-wire SPI, I2C, UART, and a 5-channel hardware comparator, enabling direct connection of analog and digital sensors without external glue logic. Architecturally, the PIC24FV16KA301 uses Microchip's modified Harvard RISC core with a 16-bit instruction word and 24-bit instruction address space, allowing linear code memory up to 16M instructions and supporting C-compiled firmware with the MPLAB XC16 toolchain. Hardware-level support is provided for low-power modes including Sleep, Deep Sleep, and Retention modes, with wake sources from RTCC, external interrupts, and DSWDT. PPS and the unified analog front-end mean the same silicon can be reused across product variants simply by changing firmware, which simplifies inventory for OEMs. Typical applications include battery-powered IoT sensor nodes, e-metering and utility metering, capacitive touch user interfaces, medical handheld devices, low-power industrial sensors, and consumer appliances. The wide 1.8V to 5.5V VDD range lets the same part run from a single Li-ion cell, two AAs, or a regulated 3.3V rail, eliminating the need for separate hardware variants for different power domains. When designing with this device, prioritize CTMU calibration on first power-up and size the decoupling network to at least 100nF + 10uF bulk per VDD/AVDD pair. A 32.768kHz crystal is recommended for RTCC accuracy; without it, deep-sleep RTC drift can exceed 5% and break long-interval timer applications.

Key features include 16KB (5.5K x 24) self-programmable Flash, 2KB SRAM, 512 bytes EEPROM, a 12-bit ADC with up to 16 input channels, a Charge Time Measurement Unit (CTMU) for capacitive touch and precise timing, and a 17-bit Single Cycle 16x16 Multiply hardware engine. The 5V-tolerant I/O allows direct interface with legacy 5V logic or analog signal-conditioning front-ends without level shifters. The architecture supports two supply rails — a 3.3V VDD for the core and an optional 5V-tolerant AVDD for analog — and peripherals include UART, SPI, I2C, and a parallel master port (PMP). Microchip's MPLAB X IDE with the XC16 compiler provides a full tool chain for code development and on-chip debugging, including built-in support for the device's unique low-power modes. Typical applications include low-power wireless sensor nodes, battery-powered medical instruments such as glucose meters, e-metering data loggers, and consumer remote controls. The CTMU and 12-bit ADC combination also suits capacitive-touch user interfaces. The 28-SSOP package gives a 0.65 mm pitch and a low ~1.75 mm profile, making it suitable for compact hand-held enclosures. When designing with the PIC24FV16KA302-I/SS, evaluate the VDD/AVDD decoupling network (typically 0.1 µF X7R per rail plus 10 µF bulk) and route the analog and digital grounds as a star to minimize ADC noise. Verify that the chosen sleep mode meets the application's average current budget — Deep Sleep draws only nanoamps while still waking on RTCC or external interrupts.

PIC24FV16KA302T-I/ML - 16-bit XLP MCU, 32MHz, 16KB Flash | Microchip

The Microchip Technology PIC24FV16KA302T-I/ML is a 16-bit PIC® XLP™ (eXtreme Low Power) microcontroller running at up to 32 MHz (16 MIPS) from a 1.8 V to 3.6 V supply, integrating 16 KB Flash program memory, 2 KB SRAM, and 512 B EEPROM into a 28-pin QFN package (6x6 mm). It is part of the PIC24FV16KA304 family of 20/28/44/48-pin general-purpose 16-bit Flash microcontrollers featuring XLP Technology. The 'FV' in the part number designates the wide 1.8 V to 3.6 V supply variant, ideal for battery-powered applications. What is a Microcontroller (MCU)? A microcontroller is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM and EEPROM), and programmable peripherals on one die. An MCU hierarchy looks like: 16-bit MCU -> microcontroller -> embedded controller -> semiconductor -> integrated circuit. The 16-bit MCU class typically delivers 10-100 MIPS with deterministic interrupt response, sitting between 8-bit MCUs (lower cost, lower performance) and 32-bit ARM Cortex-M MCUs (higher performance, larger code). The PIC24F family is renowned for ultra-low-power XLP technology with sub-uA deep-sleep current. Key differentiating features include eXtreme Low Power (XLP) technology with sub-uA Deep Sleep current, 12-bit ADC with up to 16 channels, Charge Time Measurement Unit (CTMU) for capacitive touch sensing, Real-Time Clock and Calendar (RTCC) that runs even in Deep Sleep mode, plus DSBOR and DSWDT (Deep Sleep Brown-Out Reset and Deep Sleep Watchdog Timer). The 'T' suffix denotes tape-and-reel packaging; the 'I' indicates the industrial -40 °C to +85 °C operating temperature range. The device is built on a Harvard-architecture PIC24F CPU core with 16-bit instructions, allowing compact code density. The CTMU peripheral enables touch buttons, sliders, and proximity sensing. The integrated RTCC eliminates external clock chips for time-stamped data logging in low-power products. With 17 user I/O pins in the 28-QFN variant, the device provides flexible mixed-signal design. Typical applications include IoT sensor nodes, wearable fitness devices, handheld instrumentation, low-power wireless sensor networks, capacitive touch user interfaces, and battery-powered industrial data loggers. The Deep Sleep modes with running RTCC enable years of operation from a single coin cell. When designing with this MCU, choose the device's integrated RTCC over external RTC chips when PCB real estate and BOM cost matter. Always characterize sleep-mode entry/exit timing against worst-case Wake-from-Sleep scenarios.
