Communications peripherals include one I2C/SPI MSSP, one UART with LIN support, and up to 25 I/O pins. The 16 KB self-programmable Flash supports In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD), enabling field firmware updates and post-assembly programming. nanoWatt XLP technology delivers typical sleep currents in the nanoampere range, watchdog and RTCC wake sources, and a low-power supervisor. Combined with 1.8-3.6V wide VDD, the device suits unregulated Li-ion or 2xAA inputs. Typical applications include low-cost sensor nodes, low-power remote controls, battery-powered thermostats, wearables, and consumer appliances that demand low standby current with 16-bit math. The E/SO operating range covers -40°C to +125°C for industrial environments. When designing with this device, place the 28-SOIC version (extended SOIC) where you need >25 I/O and through-hole-friendly PCB test points. The 32-MHz internal oscillator typically eliminates an external crystal for cost-sensitive designs, but add an external crystal when timing accuracy is critical (e.g., for LIN or USB bit-banging).

PIC24F16KL402-E/SP

PIC24F16KL402-E/SP - 16-bit XLP MCU, 16KB Flash, 28-SPDIP | Microchip

The Microchip Technology PIC24F16KL402-E/SP is a 16-bit PIC® XLP™ microcontroller featuring nanoWatt XLP eXtreme Low Power technology, 16KB Flash program memory, 1KB RAM, 512B EEPROM, and a 32MHz (16 MIPS) CPU core housed in a 28-pin SPDIP (SP) through-hole package. It targets cost-sensitive applications that need 16-bit computational headroom beyond typical 8-bit platforms while staying within tight power budgets. The device operates from 1.8V to 3.6V and integrates peripherals such as MSSP (I²C/SPI), CCP/ECCP, 10-bit ADC, comparators, and RTCC. A PIC24F 16-bit microcontroller is a member of the microcontroller family (MCU) within the broader semiconductor hierarchy: microcontroller -> embedded processor -> integrated circuit. The PIC24F line combines Microchip's classic PIC Harvard architecture with a 16-bit modified-RISC core, 16-bit wide instructions, and rich peripheral integration, giving it substantially more throughput than PIC18 (8-bit) parts at similar clock speeds. The KL402 sub-family specifically targets low-pin-count, low-power designs, providing nanoWatt XLP sleep currents in the sub-microamp range to extend battery life in IoT and portable products. Key features that differentiate this part include 16KB Flash (5.5K x 24 instruction words), 1KB SRAM, 512B EEPROM for non-volatile data storage, 22 I/O pins, 3 UART, 2 I²C, 2 SPI, up to 9-channel 10-bit ADC, 2 analog comparators, and a Charge Time Measurement Unit (CTMU) for touch or capacitance sensing. The device also supports 5-channel PWM via CCP/ECCP and includes an RTCC with calendar mode. These features make it well suited for sensor hubs, low-power wireless control nodes, and human-interface peripherals. The KL402 silicon integrates a wide operating voltage window (1.8V-3.6V), allowing direct battery operation from a single Li-Ion, two AA cells, or a 3.3V regulated rail. The nanoWatt XLP technology delivers Sleep currents as low as 20 nA typical with RTCC running, supporting multi-year battery life in always-on sensor designs. Internal PLL and oscillator options (8 MHz internal RC with PLL up to 32 MHz) remove the need for external crystals in many cost-sensitive applications, reducing BOM cost and PCB area. Typical applications include low-power wireless sensor nodes, battery-powered IoT devices, consumer remote controls, small appliances, low-cost HMI panels, energy-harvesting systems, and portable medical monitoring peripherals. In each case, the combination of eXtreme Low Power modes, ample memory, and Microchip's MPLAB X IDE + XC16 toolchain keeps firmware development fast and portable. When designing with this part, use the internal 8 MHz RC oscillator when BOM cost matters, but switch to an external crystal only if the application needs precise UART baud rates or USB timing. Always enable the watchdog timer for unattended remote nodes and use the RTCC for scheduling wake-ups rather than busy-loop delays.

PIC24F16KL402-E/SS

PIC24F16KL402-E/SS - 16-Bit 32MHz XLP MCU | Microchip

The Microchip Technology PIC24F16KL402-E/SS is a cost-effective 16-bit PIC24F flash microcontroller with a 32 MHz maximum CPU frequency, 16 KB of program Flash, 8 KB of data RAM, 512 bytes of EEPROM, and low-power nanoWatt XLP operation. It is packaged in a 28-pin SSOP for compact embedded designs. The E suffix identifies the extended-temperature option, while the SS package designation identifies the surface-mount SSOP form used by this ordering code. A microcontroller is a compact embedded-processing system that combines a processor core, memory, peripherals, and I/O in one integrated circuit. The PIC24F belongs to the 16-bit MCU category and sits within the broader embedded-controller and semiconductor hierarchy. Compared with an 8-bit MCU, the 16-bit architecture supports higher computational throughput and more efficient handling of control logic, while retaining a cost-conscious design suited to appliances, industrial controls, and portable products. PIC24F16KL402-family devices emphasize eXtreme Low Power consumption through nanoWatt XLP features, allowing energy-efficient operation in cost-sensitive embedded products. The family includes PIC18-style peripherals such as MSSP for I2C or SPI communication and CCP/ECCP modules for capture, compare, PWM, and motor-control functions. These integrated peripherals reduce external hardware requirements and simplify firmware implementation for common control tasks. The verified product listing identifies 16 KB of Flash organized as 5.5K x 24 words. Other distributor snippets describe the PIC24F core, 8 KB of RAM, 512 bytes of EEPROM, and a 3 V operating class. The manufacturer describes the family as economical, low-pin-count, low-power devices aimed at applications that require more computational capability than an 8-bit platform. One product source also describes a 2 V to 3.3 V device range, while the available verified material does not establish every detailed electrical limit. Typical uses include portable consumer products, low-cost medical testing and dispensing equipment, safety and security systems, and industrial or automotive controls. The 28-pin SSOP footprint is useful where a small package and mixed analog, digital, communication, and timing resources are needed. Designers should verify the exact pin function, peripheral availability, clock configuration, and operating limits against the manufacturer family data sheet before releasing a PCB or production firmware. A key design consideration is preserving low-power behavior after peripheral configuration. Unused pins, oscillators, timers, communications modules, and analog blocks should be initialized deliberately so the firmware does not prevent the intended nanoWatt XLP duty cycle. Decoupling, programming, clock stability, and unused-pin handling should follow the relevant Microchip guidance rather than relying on assumptions from a different PIC24F family member. This page consolidates the verified manufacturer, distributor, and cross-reference sources into an engineering-oriented overview of the PIC24F16KL402-E/SS, including available pricing, package details, application guidance, and a conservative assessment of verified drop-in alternatives.
