PIC24F16KL401-I/SS - 16-Bit 32MHz XLP MCU | Microchip
料号： PIC24F16KL401-I/SS ✓ 量产中PIC24F16KL401-I/SS 概述
A microcontroller is a programmable integrated circuit that combines a processor core, memory, and peripherals on one semiconductor device. The PIC24F16KL401 belongs to the PIC24F family of 16-bit RISC-based embedded controllers, combining general-purpose digital control with mixed-signal measurement and communication functions. Its compact 20-pin package is suitable for space-constrained embedded products that need more processing capability than an 8-bit controller without adopting a larger package.
Key device features include 16 KB of Flash memory organized as 5.5K x 24 words, 1 KB of SRAM, a 32 MHz maximum clock, and a 10-bit analog-to-digital converter. The MSSP peripheral provides I2C and SPI interfaces, while the device also supports IrDA, LIN, and UART/USART connectivity. Additional listed peripherals include CCP/ECCP and brown-out detection with reset, allowing compact designs to connect external sensors, actuators, and serial peripherals.
The PIC24F16KL401 combines a 16-bit PIC RISC core with nanoWatt eXtreme Low Power technology. This architecture is intended for cost-sensitive embedded systems in which low power, mixed-signal measurement, and multiple serial interfaces are valuable. Its 20-pin SSOP package reduces PCB area while retaining separate communication and timing resources.
Typical uses include portable consumer equipment, battery-operated sensing devices, medical test and dispensing equipment, security and safety products, and compact industrial controllers. The MSSP interface is particularly useful when a design must connect an ADC, display, sensor, or memory device through I2C or SPI.
PCB design should preserve clean grounding around the analog and power pins, route sensitive signals away from switching nodes, and follow the manufacturer’s package pin-assignment diagram. The exact decoupling architecture and clock configuration should be selected from the device’s recommended application circuits and operating conditions.
This page organizes the controller’s key specifications, verified package and operating details, practical design guidance, and the limited drop-in alternatives that can be established without relaxing pin-compatibility requirements.

典型应用
PIC24F16KL401-I/SS 适用于 6 应用s: Portable Consumer Electronics, Medical Test and Dispensing Equipment, Battery-Powered Sensor Nodes, Security and Access-Control Systems, Industrial Sensing and Control, Compact Communication Accessories.
Portable Consumer Electronics
The PIC24F16KL401-I/SS fits portable products that need more control capability than an 8-bit MCU while retaining a compact 20-pin SSOP footprint. Its 16-bit PIC RISC core operates up to 32 MHz, and 16 KB of Flash supports embedded control, user-interface logic, and communication routines. The 10-bit ADC can support battery-state, touch, or analog-sensing tasks, while nanoWart XLP operation is valuable in duty-cycled products. Designers should use the low-power modes intelligently because total energy use depends on sensor activity, regulator efficiency, and how often the controller wakes.
推荐
Medical Test and Dispensing Equipment
The PIC24F16KL401-I/SS is appropriate for compact medical testing and dispensing equipment requiring deterministic embedded control and mixed-signal measurement. Its 10-bit ADC supports basic analog monitoring, while I2C and SPI provide connections to sensors, displays, memories, and actuator controllers. The 32 MHz maximum clock and 16 KB of Flash leave room for calibration logic, state machines, communications, and safety checks. For clinical equipment, validate the complete signal chain, isolation strategy, firmware limits, and regulatory requirements rather than relying on component specifications alone.
推荐
Battery-Powered Sensor Nodes
The PIC24F16KL401-I/SS can serve as the control and communications device in a battery-powered sensor node. Its nanoWart XLP architecture is designed for low-power embedded operation, while the MSSP peripheral supports I2C or SPI sensor connections. A 10-bit ADC can perform basic analog measurements, and 1 KB of SRAM can support short-lived buffers and control state. Energy performance depends on matching the clock mode and sleep states to the measurement cycle. Keep the radio and high-load peripherals disabled during idle periods, and account for regulator quiescent current when calculating battery life.
推荐
Security and Access-Control Systems
The PIC24F16KL401-I/SS is suitable for compact access-control, alarm, and security peripherals where multiple interfaces and compactness matter. UART/USART, LIN, IrDA, I2C, and SPI connectivity allows the controller to coordinate a keypad, reader, indicator, lock mechanism, or remote module. The CCP/ECCP peripherals support timing and capture functions, and brown-out detection with reset helps maintain controlled startup behavior. Security-critical designs should add suitable authentication, tamper response, and safe-state mechanisms rather than treating general-purpose MCU features as a complete security solution.
推荐
Industrial Sensing and Control
The PIC24F16KL401-I/SS can serve as a local controller in compact industrial sensing equipment operating from a 2.5 V to 3.3 V supply. Its -40°C to +85°C industrial temperature range supports applications beyond ordinary consumer environments, while I2C and SPI allow connection to sensors and actuators. The 10-bit ADC can monitor process or diagnostic signals, and CCP/ECCP provides useful timing resources. Designers should protect I/O paths against industrial transients, maintain clean analog grounding, and verify that external interfaces and regulators remain compatible with the MCU’s voltage limits.
推荐
Compact Communication Accessories
The PIC24F16KL401-I/SS is suitable for compact phone accessories, portable media controls, and other communication-oriented accessories where several serial interfaces are useful. IrDA, LIN, UART/USART, I2C, and SPI connectivity can support a sensor, display, transceiver, or local accessory controller. Its 16-bit core and 32 MHz maximum clock provide responsive protocol handling and application logic in a 20-pin SSOP. To minimize system size, place the MCU close to its serial partners, use a dedicated decoupling network near the supply pins, and apply the manufacturer’s recommended layout for clock and sensitive signals.

设计说明
Assign the PCB footprint from the manufacturer’s 20-pin SSOP drawing and confirm whether the assembly process requires a wider lead-to-lead pattern than the minimum package body width. Keep the exposed supply and ground connections on short, low-impedance paths, place the required decoupling capacitor adjacent to the device, and avoid routing high-current or fast-switching traces beneath sensitive MCU inputs.
Design the 2.5 V to 3.3 V supply path so its voltage remains within the device limits at the MCU pins. Account for transient load current when the 32 MHz clock is active, and verify brown-out behavior against the system’s reset requirements. For battery-powered operation, select regulator efficiency and quiescent current together with the MCU’s nanoWart XLP modes; a low-power controller cannot offset losses in an inefficient supply stage.
Route the 10-bit ADC input directly to its assigned pins and keep analog traces short, away from I2C, SPI, UART, and switching-supply nodes. Use a quiet ground reference and a stable source impedance appropriate for the sampling scheme. When an external clock is used, preserve the required routing and grounding from the manufacturer’s timing guidance. Review pin multiplexing in firmware so alternate digital functions do not disturb sensitive analog measurements.
Do not assume that the 20-pin SSOP PIC24F16KL401 pinout matches a 20-pin QFN, MSOP, or another PIC24F family member. Confirm the complete pin table, programming connections, oscillator options, I/O voltage limits, and alternate-function assignments for the exact base device. The PIC24F16KL401-E/SS has the same package outline, but its temperature ordering code must satisfy the product’s environmental requirement before it is used as a substitution.
合规信息
The -I ordering code identifies the industrial-temperature device and does not by itself establish AEC-Q100 qualification. Confirm environmental, material, and automotive compliance using the current Microchip product declaration and the exact ordering code.
