PIC16F687-I/P - 20MHz 8-Bit Flash MCU | Microchip
MPN: PIC16F687-I/P ✓ AktifPIC16F687-I/P Genel Bakış
A PIC16F-series microcontroller combines a reduced-instruction-computing core, programmable Flash memory, RAM, EEPROM data memory, and digital peripherals in one device. The PIC16F687 belongs to Microchip's mid-range PIC family, where the architecture provides simple programming, deterministic peripheral operation, and a compact platform for embedded control. Its stated 2.0-5.5 V operating-voltage range supports low-voltage embedded systems.
The MCU provides 3.5 KB of Flash memory, 128 bytes of RAM, and 18 I/O pins, making it suitable for control, sensing, communication, and small automation tasks. The provided sources identify the part as a 20-pin Flash-based, 8-bit CMOS microcontroller and describe its operating voltage as 2.0-5.5 V. Some distributor snippets specify 4.5-5.5 V for a related operating specification, so the applicable supply limits should be confirmed against the manufacturer datasheet for the exact operating mode.
PIC16F687-I/P is identified in the supplied data as an active lifecycle part. The -I designation indicates the industrial temperature-grade ordering variant, while /P denotes the plastic through-hole package format. Because the provided search results do not include a complete verified pinout, electrical timing table, peripheral inventory, or lifecycle statement from the manufacturer page, those values remain marked as data needed rather than being inferred.
Typical applications include compact industrial controllers, sensor nodes, simple motor-control interfaces, instrumentation, and low-power embedded systems. Its 18 I/O pins can support digital inputs, outputs, and multiplexed peripheral functions when the device is operated within the limits defined by the datasheet. Programming requires the appropriate PIC programmer and firmware configuration for clock, peripherals, and I/O assignments.
For PCB design, use the manufacturer pinout and package drawing rather than the abbreviated distributor descriptions. Confirm oscillator requirements, decoupling, programming connections, and the intended I/O mapping before layout release. When sourcing, compare the exact -I/P ordering code rather than relying only on the base PIC16F687 name, because package and temperature variants can have different ordering suffixes.

Tipik Uygulamalar
PIC16F687-I/P için uygundur 6 uygulamas: Embedded Industrial Control, Sensor Monitoring Node, Simple Motor-Control Interface, Instrumentation and Data Acquisition, Appliance Control Board, Low-Voltage Embedded System.
Embedded Industrial Control
PIC16F687-I/P fits compact control boards that monitor digital inputs and drive relays, indicators, or actuator-enable signals through its 18 I/O pins. The 20 MHz PIC16F core provides deterministic processing for simple sequencing and state-machine tasks, while the 20-PDIP package simplifies through-hole prototypes, automated insertion, and repair. Firmware must stay within the verified 3.5 KB Flash and 128-byte RAM limits, and unused pins should be configured according to the exact manufacturer datasheet.
Önerilen
Sensor Monitoring Node
PIC16F687-I/P can supervise a small sensor node when the measured signals are digital or connected through compatible peripheral functions. Its 18 I/O pins provide resources for sensor-enable, alarm, status, and communication-control signals, and the Flash memory supports configuration plus application firmware. The supplied data does not specify analog channels or communication peripherals, so the design must verify those functions in the exact datasheet before assigning sensors or expecting a specific serial interface.
Önerilen
Simple Motor-Control Interface
PIC16F687-I/P can manage a low-complexity motor-control interface when the system uses discrete driver logic and the application requires only sequencing, limit handling, and fault reporting. The 20 MHz clock and 18 I/O pins provide basic control resources, but the supplied data does not confirm dedicated PWM, comparator, or motor-driver peripherals. Engineers should verify timer and PWM availability in the manufacturer documentation and use an external transistor or driver stage where required.
Önerilen
Instrumentation and Data Acquisition
PIC16F687-I/P is suitable for compact instrumentation front ends that need digital control, status reporting, and local processing of externally conditioned signals. A 20-PDIP package allows straightforward bench-prototype assembly and through-hole repair, while 3.5 KB of Flash can hold a focused control program. The device's actual ADC, comparator, timer, and communication resources are not supplied in the verified snippets, so analog acquisition and external interface choices require datasheet confirmation.
Önerilen
Appliance Control Board
PIC16F687-I/P can support appliance and equipment control functions such as button input, operating-state sequencing, fault flags, and discrete output control. Its compact 20-pin through-hole package is useful for cost-sensitive boards where automated through-hole assembly and maintenance are preferred. Firmware should include startup and brownout handling, and the board layout should provide reliable programming access plus the decoupling and protection required by the final power environment.
Önerilen
Low-Voltage Embedded System
PIC16F687-I/P is appropriate for small embedded systems operating from a low-voltage supply when the selected operating mode remains within the verified voltage requirements. The 8-bit architecture and 18 I/O pins support compact control functions without a large external processor. Because the supplied sources contain conflicting voltage statements, the power-supply design must use the exact manufacturer operating table and verify brownout, startup, and clock behavior across the intended rail.

Tasarım Notları
Use the exact 20-PDIP manufacturer pinout and land pattern for PIC16F687-I/P rather than relying on the base-family name or a distributor package summary. Route programming, clock, supply, ground, and I/O nets only after checking the manufacturer package drawing. Keep traces short where switching or high-current signals enter the board, and preserve access to programming and test points for production validation.
Resolve the supplied 2.0-5.5 V versus 4.5-5.5 V source discrepancy before selecting the supply. Confirm the exact voltage, frequency, and operating-mode limits in the manufacturer datasheet. Place the required bypass capacitors near the device power pins using the manufacturer layout guidance, and verify brownout and startup behavior with the intended clock configuration.
Do not treat PIC16F687, PIC16F687-I, and PIC16F687-I/P as interchangeable ordering descriptions. The suffix identifies the grade and package, and a different package can require a different PCB footprint. Also do not assume that a candidate listed by a cross-reference search is pin-compatible until its pin names, supply limits, memory map, peripheral functions, and programming behavior have been checked.
Uyumluluk Bilgisi
A distributor result describes the package as lead-free, but RoHS, REACH, halogen-free, and conflict-minerals status were not supplied. AEC-Q100 is not applicable because the target is a general-purpose microcontroller rather than an explicitly automotive-qualified device.
