PIC16F54-I/SO Ringkasan

The Microchip Technology PIC16F54-I/SO is an 8-bit PIC16 flash microcontroller rated for 20 MHz operation, with 768 bytes of program memory and 25 bytes of data RAM. It is supplied in an 18-pin SOIC package and provides 12 I/O ports for compact embedded-control designs.

A microcontroller is a programmable semiconductor that combines a processor core, memory, I/O, and control peripherals on one integrated circuit. The PIC16F54 belongs to the PIC16 family of 8-bit microcontrollers and uses the PIC16RISC architecture. Its compact instruction set is intended for cost-sensitive appliances, industrial controls, security equipment, and simple embedded products that need deterministic control rather than a high-performance processor or large memory capacity.

The verified product information identifies 33 single-word instructions and 200 ns instruction execution. The device uses flash-based program memory, allowing firmware to be programmed and updated through the manufacturer-supported programming process. Its 768-byte flash area is organized as 512 words by 12 bits, while the 25-byte RAM provides working storage for control logic, state variables, and small data buffers.

PIC16F54-I/SO combines a 20 MHz maximum clock with 12 general-purpose I/O ports in an 18-SOIC surface-mount package. The 12 I/O pins make the device suitable for simple control panels, digital inputs, relay or switch interfaces, sensor conditioning, and sequential automation functions. Because the verified data does not provide every peripheral detail, designers should consult the manufacturer datasheet for exact port direction, reset behavior, oscillator options, and electrical limits.

Typical applications include home appliances, security systems, motor-control interfaces, industrial automation, and consumer entry-level products. The 18-pin package is easy to route on a conventional through-hole-style or mixed-technology PCB, although designers should confirm land-pattern dimensions and pin functions before layout release.

When replacing a device, verify the exact package suffix, operating-temperature grade, flash memory, I/O count, and clock requirement. Use the manufacturer datasheet as the authoritative source for pinout, electrical characteristics, programming, and application limits.

This page combines verified distributor specifications, official Microchip product information, application guidance, and replacement analysis. It distinguishes confirmed data from parameters that still require datasheet review rather than inventing missing electrical or mechanical values.

Aplikasi Biasa

PIC16F54-I/SO patut untuk 6 aplikasis: Home Appliance Control, Security and Access Control, Industrial Automation Interface, Simple Motor Control Interface, Digital Sensor Interface, Consumer Product Sequencing.

🏠

Home Appliance Control

PIC16F54-I/SO fits compact appliance controllers because it combines a 20 MHz PIC16 core, 768 bytes of Flash program memory, 25 bytes of RAM, and 12 I/O ports in an 18-SOIC package. Those resources support relay sequencing, button input scanning, motor timing, status indication, and simple safety-state logic. The small instruction set and Flash memory make the device suitable for fixed-function controls rather than feature-heavy appliances. Designers should use the datasheet to confirm oscillator, reset, and I/O electrical details before production.

🛡️

Security and Access Control

PIC16F54-I/SO can support simple keypad, lock, request-to-exit, or alarm-interface functions where a deterministic 8-bit controller and 12 I/O ports are more useful than a high-performance processor. Its 768-byte Flash area can hold a compact state machine, while 25 bytes of RAM supports temporary status and debouncing variables. The 18-SOIC package allows straightforward assembly into a controller board. Confirm input thresholds, output drive limits, oscillator behavior, and any security requirements in the manufacturer datasheet.

🏭

Industrial Automation Interface

PIC16F54-I/SO is suitable for small industrial automation modules requiring discrete control of relays, lamps, selectors, and digital sensors. The 20 MHz clock provides timing headroom for debounce, scan, timeout, and step-sequence routines, while 12 I/O ports reduce the need for additional digital expansion. The -I ordering code supports an industrial-grade interpretation, although the exact temperature range must be verified. Use robust isolation, protection, grounding, and surge-control components around external field wiring rather than relying on the MCU alone.

⚙️

Simple Motor Control Interface

PIC16F54-I/SO can manage a basic motor-control interface, such as direction sequencing, timed relay drive, speed-command decoding, or interlock logic, when the external power stage handles current switching. The 20 MHz execution rate supports compact control loops, and the 12 I/O ports can connect limit switches, enable inputs, and driver-control signals. Because the MCU is not a high-current motor driver, use appropriate transistors, driver ICs, flyback protection, and isolation. Validate timing and electrical limits against the final actuator and power-supply design.

🧩

Digital Sensor Interface

PIC16F54-I/SO can supervise discrete sensors such as limit switches, photo-interrupts, contact sensors, and digital status lines through its 12 I/O ports. A compact firmware loop can debounce inputs, update state variables, prioritize alarms, and drive indicator outputs. Its 25 bytes of RAM is modest, so applications should avoid large buffers and complex protocol stacks. For analog sensors, add an external converter or amplifier and confirm all timing, pull-up, output-drive, and supply requirements in the datasheet.

📱

Consumer Product Sequencing

PIC16F54-I/SO is appropriate for simple consumer products that require startup sequencing, button handling, mode selection, display or indicator control, and timed state changes. Its Flash-based 768-byte memory is useful for compact firmware, and its 18-SOIC package is compatible with conventional small-board assembly. The -I grade should be checked against the product’s environmental requirements, while the 20 MHz clock specification supports responsive event handling. Keep firmware within the verified memory limits and validate all electrical assumptions in the Microchip datasheet.

What is the operating voltage of PIC16F54-I/SO?
The verified product data identifies PIC16F54-I/SO as a 2.5 V, 3.3 V, and 5 V-capable microcontroller, while another distributor listing states a 4.5 V to 5.5 V operating range. The exact voltage limits should be confirmed in the Microchip datasheet for the selected clock and operating mode. Because the supplied results contain conflicting distributor summaries, no single operating-voltage range is asserted here.
How much Flash memory and RAM does PIC16F54-I/SO have?
PIC16F54-I/SO has 768 bytes of Flash program memory organized as 512 words by 12 bits and 25 bytes of data RAM. According to the verified DigiKey and Mouser product summaries, the device also provides 12 I/O ports. These resources suit small control routines, digital I/O logic, state machines, and compact appliance controllers rather than storage-heavy applications.
What clock speed does PIC16F54-I/SO support?
PIC16F54-I/SO supports a maximum clock frequency of 20 MHz. The official Microchip product page describes the PIC16F54 as a FLASH-based 8-bit microcontroller with 200 ns instruction execution. In practice, the operating clock must be selected and configured within the limits described in the manufacturer datasheet, including any oscillator and supply-voltage constraints.
Where can I download the PIC16F54 datasheet PDF?
The verified Microchip PDF is the authoritative datasheet source for PIC16F54-family electrical characteristics, pin functions, programming information, and application details. It is available at https://ww1.microchip.com/downloads/aemDocuments/documents/OTH/ProductDocuments/DataSheets/41201B.pdf. The official product page is https://www.microchip.com/en-us/product/PIC16F54.
What is the pinout of PIC16F54-I/SO?
PIC16F54-I/SO is an 18-SOIC package, but the supplied verified snippets do not provide the complete numbered pin assignment. The pinout should therefore be taken from the Microchip datasheet rather than inferred from neighboring PIC devices. Confirm all 18 pin numbers, power pins, I/O names, oscillator connections, reset behavior, and programming pins before making a replacement or PCB change.
Where can I buy PIC16F54-I/SO online?
PIC16F54-I/SO is listed by DigiKey, Mouser, LCSC Electronics, Arrow, and Octopart in the supplied data. LCSC lists a starting price of $0.977, while distributor pages provide availability, pricing, and datasheet links. Commercial stock and lead time can change, so confirm the current quantity, delivery date, authorized sourcing, and manufacturer lifecycle status at the distributor before purchasing.
What is the price of PIC16F54-I/SO?
The supplied LCSC result lists PIC16F54-I/SO from $0.977, and the JSON tiers use that verified starting price as of 2026-10-23. Other distributor prices may differ by quantity, stock, and shipping terms. Treat $0.977 as a source-reported starting price rather than a guaranteed quote for every order quantity.
Is PIC16F54-I/SO in stock?
The supplied distributor results indicate that PIC16F54-I/SO is offered for purchase, and the LCSC result explicitly describes the component as in stock. DigiKey and Mouser also provide product listings with availability and ordering information.

What is the lead time for PIC16F54-I/SO?
The verified data does not provide a fixed manufacturer or distributor lead time for PIC16F54-I/SO. The product is listed by multiple distributors, but listing availability does not guarantee immediate delivery for every quantity. Request a written quote and stock confirmation from DigiKey, Mouser, LCSC, or Arrow, then use that supplier-confirmed date for production planning.
Can PIC16F54-I/SO be used in industrial temperature applications?
The -I suffix in PIC16F54-I/SO indicates an industrial-grade ordering option according to the verified naming and distributor data, but the supplied snippets do not provide the exact temperature limits. Use the Microchip datasheet to confirm the operating-temperature range and all electrical ratings. The device is structurally suited to industrial-control designs when those ratings and the required operating conditions are verified.
What can replace PIC16F54-I/SO?
The verified cross-reference data identifies PIC16F54-I/SSG, PIC16F54-I/SS, PIC16F54-I/PG, PIC16F54T-I/SSG, and PIC16F54T-E/SO as related Microchip options, but several use different package suffixes and are not guaranteed to share the exact 18-SOIC footprint. Treat them as candidates for engineering review, not automatic drop-in replacements. Confirm package, pinout, memory, voltage, timing, temperature grade, and programming compatibility first.
Is PIC16C54A-20/SO the same as PIC16F54-I/SO?
PIC16C54A-20/SO is not automatically interchangeable with PIC16F54-I/SO. The verified comparison result identifies both as 8-bit PIC devices, while the target part is explicitly Flash-based with 768 bytes of program memory and 12 I/O ports. Verify pin compatibility, memory organization, supply voltage, oscillator requirements, reset behavior, and firmware implications before considering a substitution.
What is the best drop-in replacement for PIC16F54-I/SO?
No verified cross-brand drop-in replacement was supplied for PIC16F54-I/SO. The strongest related Microchip candidates include PIC16F54T-E/SO and PIC16F54-I/SSG, but the available evidence does not prove exact 18-SOIC pin compatibility for every candidate. For a production replacement, use Microchip’s cross-reference search or obtain an authoritative pin-and-code compatibility chart, then validate firmware and timing.
What are the key specifications of PIC16F54-I/SO engineers should know?
PIC16F54-I/SO is a Microchip 8-bit Flash PIC microcontroller with 20 MHz maximum clock, 768 bytes of program memory organized as 512 x 12, 25 bytes of RAM, 12 I/O ports, and an 18-SOIC package. According to the verified Microchip and distributor data, it also provides 200 ns instruction execution and a 33-instruction set. These specifications define its suitability for compact embedded-control and I/O-oriented products.
Is PIC16F54-I/SO RoHS compliant?
The supplied verified results do not explicitly state whether PIC16F54-I/SO is RoHS compliant, so its RoHS status is unknown in this record. Do not infer compliance from the manufacturer name, package, or distributor listing. Check the current Microchip product documentation, declarations, or supplier material for the exact ordering code and destination market requirements.

Catatan Desain

Before releasing a PIC16F54-I/SO design, define the supply source, voltage range, decoupling network, and maximum current budget using the manufacturer datasheet. The supplied distributor summaries are inconsistent on the operating-voltage range, so do not select capacitors or regulators from the snippets alone. Place the required supply bypass capacitor close to the device power pins and verify startup, reset, and brownout behavior in the final board test.

Use an 18-SOIC footprint verified against the selected package drawing, and preserve the manufacturer-recommended pin-one orientation and pad spacing. Because the provided web results do not include a complete verified pinout, do not rely on a generic SOIC symbol. Cross-check every power, oscillator, reset, programming, and I/O connection against the PIC16F54 datasheet before fabrication.

The related MPNs listed as alternatives are not automatically interchangeable merely because they share the PIC16F54 family name. Package suffix, temperature grade, timing grade, device identity, memory map, and programming configuration must be checked. A replacement that appears similar in a distributor table can still require different firmware, a different qualification range, or a different land pattern.
