PIC16F88-I/SO - 8-Bit 20MHz Flash MCU | Microchip
MPN： PIC16F88-I/SO ✓ 啟用中PIC16F88-I/SO 概覽
A PIC microcontroller is a programmable controller built around a small RISC core, integrated memory, and peripherals for digital and analog signal acquisition. The PIC16F88 belongs to the PIC16 family of 8-bit microcontrollers and sits within the broader embedded-controller and semiconductor hierarchy. Its combination of Flash memory, EEPROM, serial interfaces, timers, and ADC channels allows one device to supervise sensors, communicate with external equipment, and generate timing or control signals.
Verified distributor data identifies 7 KB of Flash memory organized as 4K by 14 bits, 16 I/O pins, and an 18-SOIC package. The product page specifies an 8 MHz internal oscillator and 256 bytes of EEPROM. The manufacturer search result also identifies a capture/compare/PWM block, addressable USART, and a synchronous serial port configurable for 3-wire SPI or 2-wire I2C. The 7-channel, 10-bit ADC provides 1024 quantization levels over its selected reference range.
The PIC16F88-I/SO is suited to compact industrial controllers, data-acquisition modules, sensor interfaces, communication bridges, and legacy control systems. Its 16 I/O pins can support digital inputs, outputs, and multiplexed analog functions while the serial peripherals reduce the need for external interface hardware. The 20 MHz maximum frequency supports faster control-loop and communication tasks, while the internal 8 MHz oscillator can reduce dependence on an external clock source.
When laying out the PCB, use the manufacturer pin and package drawings rather than relying on generic SOIC conventions. Confirm the oscillator, programming, power, decoupling, I2C, SPI, USART, ADC-reference, and I/O connections against the datasheet. Because this is an 18-pin SOIC device, verify the exact package drawing and pin numbering before fabrication.
This page consolidates verified distributor specifications, manufacturer feature information, a datasheet reference, application guidance, and conservative replacement analysis. Pricing and availability remain time-sensitive, so confirm current quotes before procurement.

典型應用
PIC16F88-I/SO 適用於 6 應用s: Industrial Sensor Acquisition, Serial Communication Bridge, PWM and Timing Control, Legacy PIC16 Control-System Upgrade, Compact Instrumentation Controller, Embedded Serial Sensor Node.
Industrial Sensor Acquisition
PIC16F88-I/SO fits compact industrial sensor-acquisition modules because it combines seven 10-bit ADC channels with 16 I/O pins and a 20 MHz maximum CPU frequency. The ADC can sample temperature, level, pressure, or potentiometer signals when their voltage range matches the MCU reference and input limits. The controller can store calibration or configuration data in 256 bytes of EEPROM, process readings, and report results through its addressable USART. Place the analog front end close to the ADC pins and follow the datasheet grounding and decoupling guidance.
推薦
Serial Communication Bridge
PIC16F88-I/SO is useful for small protocol-conversion and communication-bridge products because it provides addressable USART plus synchronous serial support for 3-wire SPI or 2-wire I2C. A design can receive data from one interface, translate or filter it, and forward it through another interface without an external protocol device. The 20 MHz maximum frequency provides control headroom, while the 18-pin package keeps the device compact. Verify pin multiplexing, logic levels, pull-ups, and bus timing against the exact package pinout.
推薦
PWM and Timing Control
PIC16F88-I/SO can serve in compact actuator and timing controllers because the manufacturer identifies a capture/compare/PWM peripheral alongside the 20 MHz maximum CPU frequency. The MCU can generate timed outputs, measure input periods, or coordinate dimming, motor, and relay functions while its 16 I/O pins provide discrete signal connections. EEPROM can retain operating parameters between power cycles. Validate timer resolution, output polarity, current limits, and external driver topology with the device datasheet and application circuit.
推薦
Legacy PIC16 Control-System Upgrade
PIC16F88-I/SO is a sensible choice for maintaining or upgrading a legacy PIC16 control board because the manufacturer describes the device as upward compatible with several earlier PIC families and provides Flash programming plus EEPROM. Existing control logic can retain familiar instruction-set and peripheral concepts while gaining a documented 20 MHz maximum frequency and integrated serial options. Migration still requires checking pin multiplexing, interrupt behavior, memory map, timing assumptions, and programmer compatibility; a footprint match alone does not prove firmware compatibility.
推薦
Compact Instrumentation Controller
PIC16F88-I/SO can act as a compact instrumentation controller for measurement panels, calibration fixtures, and laboratory-adjacent products. Seven 10-bit ADC channels support multiple analog inputs, while EEPROM provides 256 bytes for configuration values and the USART enables host communication. The 20 MHz maximum CPU frequency allows responsive sampling and control, and the 18-pin SOIC package simplifies dense board layouts. Use careful analog grounding, input filtering, calibration storage, and supply bypassing to obtain repeatable measurements.
推薦
Embedded Serial Sensor Node
PIC16F88-I/SO suits small serial sensor nodes that need local acquisition and digital communication in one controller. Its 7-channel, 10-bit ADC can monitor simple resistive or voltage-based sensors, while SPI or I2C can connect to a more capable sensor or display. The addressable USART supports a host or service interface, and EEPROM can retain node-specific settings. Because the MCU has only 18 pins, prioritize shared analog and digital functions carefully and verify that every external peripheral has compatible voltage levels.

設計說明
Use the Microchip 18-pin package drawing rather than a generic SOIC footprint. Confirm the target device's actual pin numbering and exposed or non-exposed package geometry before placing the footprint. Keep the programming interface, oscillator components, power pins, and decoupling capacitors in locations that remain accessible during manufacturing. A same-package alternative is not automatically safe until its pinout and electrical limits have been compared pin by pin.
Place local supply decoupling close to the PIC16F88-I/SO power and ground pins and follow the capacitor recommendations in the manufacturer datasheet. The verified snippets identify a 5 V part but do not provide the complete operating range, so validate supply limits, startup behavior, and programming voltage conditions before fixing the power architecture. Do not infer compatibility from the replacement candidates' 18-pin SOIC package designation alone.
Route analog inputs away from switching nodes and high-current return paths. The integrated seven-channel, 10-bit ADC is useful for sensor acquisition, but measurement repeatability depends on input filtering, reference stability, source impedance, grounding, and the datasheet sampling requirements. If the design also uses SPI, I2C, or USART, keep communication routes separated from sensitive analog traces where practical and provide the required bus pull-ups or termination.
Do not treat the verified package-only comparison results as proof of drop-in electrical or firmware equivalence. PIC16F88T-E/SO, PIC16C433T-I/SO, and PIC16C433T-E/SO are listed as same-package comparison candidates, but the supplied excerpts do not establish exact memory, peripheral, voltage, timing, or pin compatibility. Validate the candidate's datasheet, programming method, interrupt vector behavior, memory map, and package drawing before releasing a replacement BOM.
合規資訊
Compliance fields are unknown because the supplied verified web data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-mineral status. Verify these requirements with the manufacturer or current distributor documentation.
