PIC16F1518-I/SP - 8-bit 20MHz XLP MCU 28KB Flash 28-SPDIP | Microchip
MPN: PIC16F1518-I/SP ✓ Hoạt độngPIC16F1518-I/SP Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a set of peripherals onto one die. The "8-bit" refers to the width of the data path and ALU; this device sits in the hierarchy: PIC16F1518 -> PIC16F151x family -> PIC16F1xx -> PIC® XLP 16F -> 8-bit MCU -> microcontroller -> embedded controller. XLP technology targets battery-powered and energy-harvesting designs where active current in the microamp range and sleep currents below 100 nA are required.
Key features include 25 high-current source/sink I/O (25 mA per pin), 17 channels of 10-bit ADC with selectable references, two 8-bit timers (TMR0/TMR2), one 16-bit timer (TMR1), two PWM modules, an enhanced power-on/off-reset, programmable ultra-low-power brown-out reset (ULPBOR), in-circuit serial programming (ICSP), and in-circuit debug. The 28-SPDIP package exposes 25 usable I/O plus VDD/VSS and provides robust through-hole soldering for development and industrial assemblies.
Typical applications span consumer appliances, handheld instruments, sensor nodes, white goods motor control, low-cost battery monitoring, and general-purpose logic replacement. The PIC16F1518 supersedes legacy PIC16F88/PIC16F877A designs that need 28 KB Flash and a true XLP sleep profile.
When designing, prefer the LF (PIC16LF1518) variant for sub-3 V operation; the standard F variant requires 2.3-5.5 V. Add a 100 nF decoupling cap on VDD, keep ADC traces short, and route MCLR with a 10 kohm pull-up.

Ứng dụng tiêu biểu
PIC16F1518-I/SP phù hợp cho 6 Áp dụngs: Battery-Powered Sensor Nodes, White Goods Motor and PWM Control, Consumer Appliance User Interface, Handheld Test and Measurement Instruments, Industrial Process Sensor Conditioning, Automotive Interior Lighting and Switch Panels.
Battery-Powered Sensor Nodes
The PIC16F1518-I/SP fits battery-powered wireless sensor nodes thanks to its XLP active current in the microamp range and sleep current below 100 nA with ULPBOR enabled. Its 17-channel 10-bit ADC directly interfaces thermistors, photocells, and battery-divider rails without external signal conditioning. Compared to a discrete 555-timer-based sensor sampler, the PIC16F1518 reduces idle drain by orders of magnitude, extending CR2032 coin-cell life past two years at 1 sample/minute duty. The 25 high-current I/O also drive status indicators and low-side MOSFETs without buffering.

White Goods Motor and PWM Control
Two PWM channels and three timers on the PIC16F1518-I/SP make it well suited for low-cost washing-machine pump, fan-speed, and small BLDC control boards. The 20 MHz core executes 5 MIPS, easily handling 8 kHz PWM with software dead-band insertion. The 25 mA sink/source I/O directly drives logic-level MOSFET gate drivers such as the MCP14E4 without external buffers. Designers benefit from the SPDIP-28 through-hole package for hand-reworkable prototypes.
Được đề xuất
Consumer Appliance User Interface
The PIC16F1518-I/SP suits appliance front-panel UI boards with capacitive-touch replacement via ADC scanning, LED row driving, and seven-segment multiplexing. Its 25 I/O accommodate up to 7-segment digits plus key-matrix scanning, all driven from a single MCU. The 28 KB Flash holds UI state machines plus boot loader for field firmware updates via ICSP, and 1 KB RAM is sufficient for debounced key tables and LED PWM buffers.
Được đề xuất
Handheld Test and Measurement Instruments
The PIC16F1518-I/SP fits entry-level handheld multimeters, cable testers, and logic-level probes because its 17-channel 10-bit ADC digitizes voltage, current, and resistance measurements while the 20 MHz CPU executes RMS math in real time. The XLP profile lets a handheld run for hundreds of hours on two AA cells. The ICSP/ICD pins enable field re-flashing via a 6-pin header without removing the chip.
Được đề xuất
Industrial Process Sensor Conditioning
In factory-floor 4-20 mA loop and 0-10 V sensor signal conditioners, the PIC16F1518-I/SP converts analog signals, applies linearization, and drives isolated HART modem front-ends. The 10-bit ADC at 8-channel mux provides adequate resolution for 1% process instrumentation, and the SPDIP-28 socketed form simplifies replacement on legacy PLC backplanes. Industrial -40C to +85C temperature range matches IEC 60068-2-1 requirements for harsh environments.
Được đề xuất
Automotive Interior Lighting and Switch Panels
Although the PIC16F1518-I/SP itself is not AEC-Q100 qualified, it is widely used in non-safety automotive interior accessories like dome-light controllers, RGB foot-well drivers, and capacitive switch panels. The 25 mA I/O source current directly drives LED strings up to 25 mA per channel; the 2 PWM channels create soft-fade transitions. Designers targeting AEC-Q100 should migrate to PIC16F1518-I/SPVAO variants or PIC18F equivalents.

Bảo phân biệt quan trọng
- Industry-leading XLP sleep current below 100 nA (vsPIC16F1519-I/SP)
- Through-hole SPDIP-28 package for prototyping (vsPIC16F1518-I/SS)
- Lower voltage variant available in identical footprint (vsPIC16LF1518-I/SP)
Ghi chú thiết kế
Place a 100 nF decoupling capacitor on the VDD pin (pin 17) and route the VSS pin (pin 16) directly to the ground plane with a short trace. For battery-powered designs, set the ULPBOR threshold to the lowest valid value (1.9 V on the F variant, 1.65 V on the LF variant) and enable the watchdog timer (WDT) with a long timeout to minimize wake frequency.
Keep the crystal traces (pin 5 OSC2 / pin 6 OSC1) short and symmetric, surrounded by a grounded guard ring to prevent digital switching noise from coupling into the oscillator. The ICSP pins (RB6/RB7) require a 6-pin header footprint on the PCB even if not populated in production - this allows in-field firmware updates without removing the MCU.
Do not apply voltages above 5.5 V to any pin - the absolute maximum on VDD is 7.5 V but logic pins only tolerate 5.5 V. Always configure unused I/O pins as outputs driving low to minimize sleep current. The MCLR pin (pin 18) must have a 10 kohm pull-up to VDD; without it, the device will see a brown-out reset on every power-up transient.
