PIC16F88T-I/SO 20MHz 8-Bit Flash MCU | Microchip Technology
料号： PIC16F88T-I/SO ✓ 量产中PIC16F88T-I/SO 概述
A microcontroller is a semiconductor device that integrates a CPU, memory, and peripherals into one package. The PIC16F88 belongs to the PIC16 family of 8-bit Flash-based microcontrollers, a product hierarchy of embedded processors used for industrial control, instrumentation, consumer products, and compact automation systems. Its architecture supports upward-compatible migration within the PIC16 family, while the compact surface-mount package simplifies board assembly.
The PIC16F88 executes instructions with a 200 ns instruction-cycle capability and uses a compact instruction set containing 35 single-word instructions. Its 7 KB Flash memory provides substantially more program space than early PIC devices with mask-programmed or small EPROM memories. The 368-byte RAM supports working variables, stack-related operations, buffers, and intermediate control calculations.
The 18-pin SOIC package provides access to the PIC16F88’s digital I/O and core control functions while maintaining compatibility with compact leaded-surface-mount assembly. The device supports an operating supply range identified in the product information as 4.5 V to 5.5 V, making it appropriate for conventional 5 V embedded systems. Its industrial temperature designation covers -40°C to +85°C, supporting use in factory equipment, environmental controllers, and other systems requiring extended commercial-temperature operation.
Typical applications include industrial sensor nodes, temperature controllers, small motor-control systems, instrumentation interfaces, programmable timers, and compact embedded automation platforms. The 8-bit architecture and Flash memory are especially useful where straightforward control logic, low component count, and field reprogrammability matter more than high bandwidth or extensive data storage.
When designing around the PIC16F88T-I/SO, verify the exact 18-pin footprint, oscillator configuration, reset behavior, and peripheral assignments against the manufacturer’s pin and connection guidance. Provide the supply and decoupling network close to the device, keep sensitive timing or analog paths away from switching nodes, and validate firmware across the full -40°C to +85°C operating range. This page combines the manufacturer’s product description, distributor listings, parameter summaries, package information, replacement guidance, and practical engineering considerations to support design review and sourcing.

典型应用
PIC16F88T-I/SO 适用于 6 应用s: Industrial Sensor Node, Temperature and Process Controller, Compact Motor Controller, Programmable Timer and Sequencer, Instrumentation and Data Acquisition, Embedded Automation Controller.
Industrial Sensor Node
The PIC16F88T-I/SO fits compact industrial sensor nodes because its 20 MHz clock, 7 KB Flash memory, and 368 bytes of RAM are sufficient for sampling, filtering, threshold decisions, and local status handling. The 18-pin SOIC package preserves board area, while the -40°C to +85°C operating range supports equipment deployed beyond room-temperature consumer environments. A typical design reads a sensor through an available I/O or peripheral, applies calibration and control logic, then drives an indicator or actuator. Validate the specific analog path, supply regulation, and I/O assignment against the manufacturer’s pin and electrical guidance.
推荐
Temperature and Process Controller
The PIC16F88T-I/SO is appropriate for temperature or general process controllers that combine periodic measurement with deterministic control output. Its 7 KB Flash can hold acquisition routines, setpoint logic, output tables, communications handling, and fault management, while 368 bytes of RAM provides working storage for sampled values and state variables. The 200 ns instruction-cycle capability supports responsive control updates at the 20 MHz maximum clock. Use timer-based scheduling, apply suitable input filtering, and isolate the control output from noisy power stages to preserve reliable operation across the -40°C to +85°C range.
推荐
Compact Motor Controller
The PIC16F88T-I/SO can serve as the logic controller for small motors, solenoids, relays, and stepper-based mechanisms where the MCU handles sequencing rather than directly driving high-current loads. At up to 20 MHz, the device can execute motion tables, limit checks, acceleration profiles, and protective timing functions using its 7 KB Flash program memory. The 18-pin SOIC package is useful for compact control boards, while the 368-byte RAM supports position and state tracking. Place transistor drivers and protection components between the MCU and load, and verify startup, stall, and thermal conditions during design validation.
推荐
Programmable Timer and Sequencer
The PIC16F88T-I/SO is well suited to programmable timers, event counters, and sequencing appliances where multiple outputs must follow a repeatable schedule. Its timer resources and 20 MHz clock support precise time-base calculations, while 7 KB Flash provides enough room for operating modes, schedules, diagnostics, and user-selectable parameters. The 368 bytes of RAM can hold counters, stage indices, and debounce state. Use the manufacturer’s oscillator and timer guidance, avoid placing critical timing near uncontrolled switching nodes, and validate timing tolerances over the full -40°C to +85°C operating range.
推荐
Instrumentation and Data Acquisition
The PIC16F88T-I/SO can coordinate low-speed instrumentation, data acquisition, and bench-device control where the system requires local processing but modest memory capacity. The 8-bit architecture and 7 KB Flash are suitable for digitizing selected channels, scaling readings, recording events, and controlling front-panel indicators, while 368 bytes of RAM supports temporary measurement buffers. Its 18-SOIC package supports compact analyzer hardware and its 4.5 V to 5.5 V supply range simplifies conventional 5 V design integration. Confirm the accuracy limits of every analog front end separately because the MCU itself does not determine measurement precision.
推荐
Embedded Automation Controller
The PIC16F88T-I/SO provides a compact control center for embedded automation modules that coordinate digital inputs, relay outputs, indicators, and local service functions. Its 20 MHz processing capability supports responsive state-machine logic, and 7 KB Flash plus 368 bytes of RAM is appropriate for compact automation logic rather than high-end connectivity workloads. The 18-pin SOIC footprint supports automated surface-mount assembly, while the -40°C to +85°C range fits industrial equipment cabinets. Add protection for long wiring, separate logic and relay grounds where appropriate, and test start-up, brownout, and field-reset behavior.

设计说明
Assign every connection from the manufacturer’s 18-pin pin-description table and preserve the exact SOIC land pattern, pin-1 orientation, and exposed-pad requirements. Keep the oscillator network and decoupling capacitors close to their associated pins, route clocks away from relay-coil and switching-node traces, and provide a ground return path that does not share high-current return paths. Verify programming, reset, and unused-pin behavior in the final schematic.
Design the 5 V supply path for the 4.5 V to 5.5 V operating range while accounting for startup droop, inductive loads, and switching transients on the board. Place local bypass capacitance at the supply pins and isolate relay or motor return currents from sensitive logic ground where practical. Confirm brownout and reset behavior with the manufacturer’s electrical characteristics, and test the complete system at maximum load because the controller may share supply nodes with noisy actuators.
Do not substitute a device based only on the 18-SOIC package. Confirm Flash size, RAM, timer resources, oscillator configuration, I/O functions, interrupt behavior, supply limits, and temperature grade. The PIC16F88 and PIC16LF88 families use related packages but can differ in operating voltage or internal features, so an apparent pin-compatible alternative may still require firmware, brownout, or power-supply changes. Validate the complete operating range before production release.
Treat the oscillator pins as sensitive high-impedance nodes and keep their copper and component placement compact. Avoid routing switching-regulator, motor, or relay-node copper beneath the MCU, oscillator, or analog inputs. If the board includes external sensors, maintain separation between sensing paths and digital return currents. Ground and power planes should be continuous where possible, with deliberate isolation rather than fragmented plane cuts.
