PIC16LF15355-I/SP 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and a programmable set of peripheral blocks. The PIC16 family is a Harvard-architecture 8-bit MCU lineage; PIC16LF15355 sits inside the PIC16(L)F153xx series that bundles Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLC), Complementary Waveform Generator (CWG), and Numerically Controlled Oscillator (NCO) alongside conventional ADC, DAC, comparators, and PWM timers. In the broader taxonomy, an 8-bit MCU belongs to embedded controllers, which sit under microcontrollers, which themselves are a sub-category of microprocessors and digital ICs.
Key features include 4 PWM channels, an on-chip 5-bit and 10-bit DAC, multiple comparators, a 10-bit ADC, 4 Configurable Logic Cells, 2 EUSART (Enhanced USART) modules, and SPI / I2C peripherals. The device is well known for low-power operation, with multiple low-power sleep modes engineered to extend battery life in IoT endpoints and energy-harvesting applications.
Typical applications span low-power sensor nodes, battery-backed metering, IoT end nodes, consumer white goods, industrial control logic, and any embedded design requiring deterministic 8-bit performance and Microchip footprint mature. The 28-SPDIP package remains attractive for prototype builds, educational labs, and through-hole assembly lines that prefer socketed or hand-soldered parts.
When designing with this part, plan Vdd decoupling close to the pin pair with at least 100 nF plus bulk capacitance matching the load transients. Ensure ICSP programming header accessibility if firmware updates are anticipated, and verify MCLR pull-up configuration against the application's brown-out and reset requirements.

일반적인 애플리케이션
PIC16LF15355-I/SP 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node, Industrial Control Logic Module, Consumer White Goods Remote Keypad, Automotive Accessory Sub-Controller, Educational MCU Trainer and Hobby Board, Energy-Harvesting Wireless Switch.
Battery-Powered IoT Sensor Node
The PIC16LF15355-I/SP's eXtreme Low-Power (XLP) architecture and 1.8V minimum operating voltage make it ideal for battery-powered IoT endpoints such as wireless environmental monitors and wired-up wireless sensor nodes. Its 1 KB SRAM and 14 KB Flash accommodate a small sensor-fusion or RTOS footprint, while the 10-bit ADC, comparator, and CLC blocks enable event-driven wake cycles that keep average current under 1 uA. Core Independent Peripherals run autonomously while the CPU sleeps, extending coin-cell life to multi-year ranges in duty-cycled applications. Recommended companion devices: MCP3339EXL (low-power digital input adapter) and MCP9700A (analog temperature sensor).
추천
Industrial Control Logic Module
The PIC16LF15355-I/SP fits industrial control logic applications such as PLC expansion modules, conveyor controllers, and wired-up industrial HMI sub-controllers. The 4 PWM channels drive motor or solenoid drivers, while the 10-bit ADC reads 4-20 mA current-loop sensors with adequate resolution. The 2 EUSART blocks bridge RS-485 and RS-232 buses simultaneously, and the SPDIP-28 through-hole package simplifies prototype panel wiring. Industrial -40C to +85C operation covers most factory-floor installations, and the configurable logic cells (CLC) implement glue logic without external gates, lowering BOM cost.

Consumer White Goods Remote Keypad
The PIC16LF15355-I/SP serves consumer white-goods remote keypads and display controllers where its combination of PWM-driven LED backlighting, ADC-based touch or rotary inputs, and SPI/I2C bus to neighbouring LCDs pins comes together. The 5-bit and 10-bit DAC enables variable-brightness backlight control without extra PWM channels. Low-voltage operation matches 2xAA battery supplies, and XLP sleep extends shelf life between battery changes to several years of standby. The SPDIP-28 package is convenient for hand-soldered prototypes and small-batch consumer electronics.
추천
Automotive Accessory Sub-Controller
While the -I industrial temperature grade covers standard cabin applications, the PIC16LF15355-I/SP can power automotive accessory sub-controllers such as seat heaters, mirror adjusters, and interior LED drivers under 12V-high-clamp supplies. The 4 PWM channels drive multiple LED strings or motor coils, while the CLC implements custom debounce and timing logic without code overhead. The 1.8V-3.6V supply range accommodates post-regulator rails from buck converters. For under-hood applications requiring AEC-Q100, the PIC16LF15355-E/SP extended-temperature variant or Q1-qualified alternates should be considered.
추천
Educational MCU Trainer and Hobby Board
The PIC16LF15355-I/SP is well suited to educational MCU trainers and hobby prototyping boards due to its 28-SPDIP through-hole package, which is socket-friendly and easy to handle in a classroom setting. The PIC16 instruction set is mature and well-documented in textbooks; students can experiment with PWM, ADC, DAC, comparators, and communication peripherals without sacrificing code space. ICSP programming via the on-chip debug header allows iterative code-and-test workflows. PICkit programmers and Curiosity development boards provide out-of-the-box tooling for new learners.
추천
Energy-Harvesting Wireless Switch
The PIC16LF15355-I/SP enables energy-harvesting wireless switches such as EnOcean-compatible push-button transmitters where its XLP sleep current of below 1 uA and rapid wake time are critical. The CLC blocks detect the switch actuation event without CPU intervention, and the EUSART module transmits the event to a receiver MCU within microseconds of the press. The 1.8V minimum supply accepts direct rectified output from piezoelectric or thermoelectric harvesters, eliminating the need for boost converters in compact designs. The 14 KB Flash accommodates custom protocol stacks and encryption libraries.

설계 노트
Decouple VDD/VSS pairs with at least 100 nF ceramic capacitors placed within 3 mm of each VDD pin, and add a bulk 10 uF tantalum or ceramic capacitor at the supply entry. For XLP sleep operation at sub-microamp currents, use an LDO with low quiescent current such as the MCP1700. The LF variant's 1.8V minimum supply allows direct connection to 2xAA alkaline cells without boost regulation.
Place the ICSP programming header (MCLR, ICSPCLK, ICSPDAT, VDD, VSS) in an accessible location with a 0.1 inch pin spacing. Keep traces to the MCLR pin short, and place a 10 kohm pull-up resistor close to the MCLR pin. Route analog signals (ADC, comparators, DAC) away from PWM and digital switching signals to minimize coupling.
Do not exceed the 3.6V absolute maximum VDD rating of the PIC16LF15355 (LF variant). Ensure MCLR is never left floating - even with internal MCLR disabled, a floating MCLR pin can cause spurious resets. When using the internal HFINTOSC, verify the OSCTUNE setting matches the application's frequency accuracy requirement; for UART communication above 9600 baud at 32 MHz, consider the PLL or a calibrated oscillator.
The PIC16LF15355-I/SP's SPDIP-28 package has a typical theta_JA around 70 C/W in still air, allowing operation at full industrial temperatures without active cooling. Estimated: at ambient 25C and typical MCU consumption under 20 mA at 3.3V (66 mW), junction rise is approximately 4.6 C, well within the 85C industrial ceiling. For high-temperature operation, orient the package to maximise airflow across the die side.
