PIC16F54-E/SS - 8-Bit Flash MCU, 18-Pin SSOP | Microchip
부품 번호: PIC16F54-E/SS ✓ 활성PIC16F54-E/SS 개요
A PIC16F54 microcontroller belongs to the PIC16 family of 8-bit RISC microcontrollers. Within the semiconductor hierarchy, it is a microcontroller, embedded controller, and programmable logic device used to execute firmware that senses inputs, controls outputs, and coordinates digital functions. Its compact architecture is aimed at cost-sensitive embedded products where a small instruction set, straightforward peripherals, and a modest memory footprint are more useful than high computational throughput.
The verified features emphasize simplicity rather than benchmark performance. Program storage is 0.77 KB, while 25 bytes of RAM provide working memory. Twelve I/O pins allow the device to interface with switches, indicators, sensors, and external logic. Its 33-instruction set and 200 ns execution figure make it useful for straightforward control loops, while flash memory permits repeated programming and firmware updates. The target is offered in the compact SSOP-18 surface-mount package for space-conscious assemblies.
The PIC16F5X architecture uses 12-bit-wide instructions designed for code efficiency within an 8-bit device class. The manufacturer describes the PIC16F54 as combining a 200 ns instruction-execution capability with only 33 single-word instructions. This compact instruction repertoire simplifies firmware development for simple sequencing and control tasks. Because available memory is limited, effective designs should minimize library overhead, avoid unnecessary buffering, and use compact control logic.
Typical uses include appliance control, small industrial automation modules, simple sensor interfaces, automotive accessories, and entry-level consumer products. The 12 available I/O pins make the device appropriate for compact products that require discrete digital control rather than high-speed communications or a large user interface. The extended-temperature ordering also makes it a candidate for industrial and automotive environments, subject to the complete manufacturer specifications and system qualification.
PCB design should preserve the exact SSOP-18 footprint and follow the manufacturer's pinout and recommended decoupling guidance. Because programming, configuration, and brownout behavior are sensitive to power and clock conditions, designers should consult the PIC16F54 datasheet before fixing supply voltage, decoupling capacitance, oscillator configuration, and programming connections. A complete SSOP-18 land pattern and all 18 pin assignments were not included in the retrieved source excerpts, so they are not asserted here.
This product record combines the verified manufacturer and distributor information with engineering-focused selection guidance, package context, and explicit data-gap handling. It also distinguishes confirmed PIC16F54 characteristics from unverified operating limits, avoiding invented electrical values. The resulting PIC16F54-E/SS reference is intended to help engineers identify the correct flash-memory 8-bit MCU and evaluate same-package PIC16F54 alternatives before starting a PCB or firmware design.

일반적인 애플리케이션
PIC16F54-E/SS 적합 용도: 6 애플리케이션s: Industrial Appliance Control, Automotive Accessory Modules, Simple Sensor Interface, Battery-Powered Device, Consumer Product Controller, Small Motor and Relay Control.
Industrial Appliance Control
PIC16F54-E/SS fits compact appliance-control modules because it provides 12 general-purpose I/O pins, 0.77 KB of flash program memory, and 25 bytes of RAM in an 18-pin SSOP package. The MCU can sequence relays, indicators, switches, and discrete sensors without requiring a high-performance processor. Its 33-instruction PICmicro architecture and stated 200 ns instruction-execution figure support deterministic, simple control logic. Designers should avoid large buffers and libraries because the working memory is only 25 bytes, and should use the exact SSOP-18 footprint rather than an SOIC-18 land pattern.
추천
Automotive Accessory Modules
The PIC16F54-E/SS is suitable for simple automotive accessory electronics where low-cost logic control and an extended-temperature ordering are desirable. Its 12 I/O pins can interface with switches, indicator lamps, and simple actuator-control stages, while flash memory allows firmware to be updated during production or service. The manufacturer identifies the PIC16F54 as adaptable to automotive applications, but the retrieved excerpts do not confirm AEC-Q100 status. Engineering approval must therefore include the full ordering code, qualification record, voltage limits, and automotive environmental validation.
추천
Simple Sensor Interface
PIC16F54-E/SS can serve as the controller for a small discrete sensor node because 12 I/O pins are available for digital inputs, alarm outputs, and status indicators. Its 200 ns instruction-execution figure and 33 single-word instructions are adequate for threshold decisions, debouncing, sampling orchestration, and fault signaling. The 25-byte RAM limit means measurements should be processed immediately rather than stored in large arrays. Analog sensor conditioning and regulated supply design remain external functions, and the complete datasheet is required to confirm the exact ports, comparator, and analog capabilities.
추천
Battery-Powered Device
PIC16F54-E/SS can support a small battery-powered controller when the application requires modest logic capacity rather than high processing throughput. The MCU provides 12 I/O pins for monitoring a battery-state signal and controlling a load switch, indicator, or simple actuator. Its compact SSOP-18 package preserves board area, and flash memory supports field reprogramming. Because no verified quiescent-current or operating-voltage figures were supplied, battery-life estimates must use the manufacturer datasheet and the selected external power components rather than assumptions made from the family description.
추천
Consumer Product Controller
PIC16F54-E/SS is appropriate for entry-level consumer products where a small microcontroller must operate a limited number of inputs and outputs. The 0.77 KB flash program memory, 25 bytes of RAM, and 12 I/O pins are suited to direct control of keys, LEDs, relays, or a simple display segment rather than a graphical user interface. Its 33-instruction set simplifies small control firmware, while the 200 ns execution figure supports responsive sequential logic. Product developers should keep the application state minimal and verify EMC, ESD, and temperature requirements for their enclosure and accessories.
추천
Small Motor and Relay Control
PIC16F54-E/SS can implement relay sequencing or a small motor-control supervisory function in an 18-pin SSOP-18 design. Twelve I/O pins allow the firmware to accept start, stop, limit, and interlock inputs while controlling relay drivers, status LEDs, and fault outputs. The device is better suited to supervisory logic than to direct high-current switching; external transistors, flyback protection, and appropriate drive components remain necessary. The 25-byte RAM and 0.77 KB flash require concise state-machine code, and timing parameters must be taken from the verified datasheet before production release.

- Small deterministic instruction set (vs ATMEGA328P-MNR)
설계 노트
Use the manufacturer SSOP-18 footprint with the specified pad dimensions and paste mask rather than adapting an SOIC-18 library symbol. Although both packages have 18 leads, their body widths and lead pitches differ. Confirm pin 1 orientation against the package drawing before generating artwork, and inspect the assembly drawing for any exposed-pad or thermal-relief requirements. The retrieved data did not provide a complete terminal table, so electrical connections must be taken directly from the current Microchip datasheet.
Determine the supply-voltage range, brownout behavior, and I/O pin limits from the complete PIC16F54 datasheet before adding external circuitry. The verified excerpts do not provide operating-voltage or absolute-maximum values, so they cannot safely establish the logic thresholds of connected sensors or actuators. Place required bypass capacitors close to the supply and ground pins according to the manufacturer layout guidance, and include a defined reset or power-control strategy if the selected configuration requires one.
Do not assume that family members with similar suffixes are automatically interchangeable. PIC16F54T-E/SS, PIC16F54-I/SSG, and PIC16F54-I/SS differ in ordering attributes that may affect temperature range or qualification. Compare the full ordering information, device configuration, programming model, and terminal assignments. Also avoid treating the related SOIC-18 PIC16F54-I/SO as a board-level substitute for the target SSOP-18 device, because the verified listings identify different package formats.
The MCU offers only 25 bytes of RAM and 0.77 KB of flash program memory, making memory planning more important than it would be on a modern general-purpose MCU. Use small state variables, avoid deep library calls, and structure firmware as a compact state machine when coordinating multiple I/O lines. Verify the final linked image size during the build so that diagnostics, bootloader code, or late feature additions do not exceed the available program-memory budget.
규정 준수 정보
The retrieved source excerpts do not explicitly state material-compliance or automotive-qualification status. The extended-temperature ordering must not be treated as evidence of AEC-Q100 qualification.
