PIC16F88-I/ML Übersicht
A microcontroller is a programmable integrated circuit that executes firmware, reads sensors, controls outputs, and coordinates embedded-system peripherals. Within the semiconductor hierarchy, the PIC16F88 belongs to Microchip's PIC16 family of 8-bit microcontrollers, Flash-based embedded controllers, and general-purpose semiconductor devices. Its compact package and mixed analog, digital, timing, and communications resources suit small control systems that need local sensing and actuator management.
The verified specifications identify a maximum clock rate of 20 MHz, 4K by 14 words of Flash program memory, 368 bytes of RAM, 256 bytes of EEPROM data memory, and 16 I/O pins. An 8 MHz internal oscillator is listed on the Microchip product page, providing a clock source for applications that do not require an external crystal. The Flash architecture permits in-circuit reprogramming, while EEPROM supports nonvolatile parameter retention between power cycles.
The PIC16F88 combines seven 10-bit ADC channels with an addressable USART and a synchronous serial interface supporting three-wire SPI or two-wire I2C operation. Capture/compare/PWM resources support timing and proportional control tasks. This peripheral mix reduces the need for external conversion or interface ICs when the design uses compatible sensors, displays, actuators, or serial transceivers.
Typical embedded uses include industrial sensing modules, compact motor controllers, instrument interfaces, environmental monitors, and low-cost connected-control products. The 28-QFN package favors dense surface-mount layouts, but exposed-pad soldering, thermal management, and pin escaping require careful PCB design. Verify the exact package drawing and pin assignment against the manufacturer datasheet before layout release.
For firmware development, use the PIC16 mid-range toolchain and confirm programming, clock, peripheral, and package constraints against the selected device documentation. The I/ML ordering code identifies the industrial temperature grade and ML package, but the supplied search data does not state the numeric temperature limits, supply voltage, ADC reference details, or electrical current ratings. Those values must be taken directly from the applicable Microchip datasheet rather than inferred.
This page consolidates verified manufacturer and distributor facts, package details, application guidance, and procurement links. It also separates explicitly verified information from missing engineering data, helping engineers locate the PIC16F88-I/ML without relying on assumed specifications or unsupported drop-in substitutions.

Typische Anwendungen
PIC16F88-I/ML ist geeignet für 6 Anwendungs: Industrial Sensor Interface, Compact Motor Controller, Environmental Monitoring Node, Serial Protocol Bridge, Measurement and Instrumentation Front End, USB-to-Serial Embedded Adapter.
Industrial Sensor Interface
The PIC16F88-I/ML fits compact sensor nodes because its seven 10-bit ADC channels, 16 I/O pins, and 8 MHz internal oscillator reduce the need for external clock and conversion circuitry. The device can acquire analog sensor values, apply calibration in Flash firmware, and report results through SPI, I2C, or USART. Its 7 KB program memory provides space for acquisition control and local processing, while 256 bytes of EEPROM can retain configuration values. Compared with a discrete ADC and communications controller, the integrated implementation reduces footprint and board complexity. The numeric supply limits, ADC acquisition timing, and accuracy specifications were not supplied, so they must be verified in the Microchip datasheet before setting measurement ranges.
Empfohlen
Compact Motor Controller
PIC16F88-I/ML can control small motors or valves when its 16 I/O pins and capture/compare/PWM resources match the actuator and feedback requirements. A designer can use PWM for speed or position modulation, an input capture function for feedback events, and the seven-channel 10-bit ADC to monitor current proxies, temperature sensors, or analog control signals. The 20 MHz maximum CPU speed supports responsive control loops, while the 6 mm by 6 mm QFN helps reduce controller-board size. Firmware must account for startup, flyback or inductive transients, current limits, and safe off-state behavior. Because the supplied evidence does not include output-driver ratings or absolute electrical limits, do not connect a motor directly without a verified driver and protection network.
Empfohlen
Environmental Monitoring Node
The PIC16F88-I/ML is suitable for a compact environmental monitor that combines analog measurements with low-rate field communications. Its seven 10-bit ADC channels can accept suitable temperature, humidity, light, or gas-sensor outputs, while SPI or I2C can connect to local sensors and USART can provide a service link. The internal 8 MHz oscillator can reduce external clock-component requirements, while EEPROM can preserve calibration or sample-interval settings. Flash firmware can convert readings into scaled values, apply thresholds, and report alarms without a separate host processor. Sensor accuracy will depend on reference voltage, excitation circuitry, calibration, and the MCU's verified ADC specifications, which are not present in the supplied excerpts and therefore must be obtained from the manufacturer datasheet.
Empfohlen
Serial Protocol Bridge
PIC16F88-I/ML can bridge embedded serial protocols because it offers a configurable synchronous port for SPI or I2C and a separate addressable USART. A firmware translator can receive data from one interface, validate or translate it, and forward it through another while firmware manages framing, timeouts, and error recovery. The 7 KB Flash capacity, 368-byte RAM, and 256-byte EEPROM are sufficient for many compact protocol converters, subject to buffer and stack requirements in the final application. Designers should map pins through the device's multiplexing rules and isolate grounds and signal levels appropriately. Exact baud rates, SPI modes, timing margins, and electrical levels are not stated in the supplied excerpts and must be checked before production release.

Measurement and Instrumentation Front End
The seven-channel 10-bit ADC and configurable communication interfaces make PIC16F88-I/ML relevant to small measurement instruments and panel controls. Multiple analog inputs can be sampled under firmware control, while PWM-capable timing resources can drive displays, indicators, or excitation signals. The internal 8 MHz clock simplifies designs that do not require a precision crystal, and the 28-QFN package supports compact front-end construction. For instrumentation-grade work, analog reference quality, ground separation, input protection, calibration, and sample timing are as important as the nominal ADC resolution. The verified excerpts do not provide voltage tolerances, reference accuracy, acquisition-time figures, or noise performance; engineers must verify those parameters and design a signal chain that keeps errors within the application's measurement budget.
Empfohlen
USB-to-Serial Embedded Adapter
PIC16F88-I/ML can serve as the application-side controller in a compact USB-to-serial or protocol-conversion assembly, although USB itself is not listed among its verified peripherals. A companion USB controller such as CP2102N can handle USB, while the PIC device manages the target UART, status LEDs, configuration, and user I/O. This separation may simplify designs that need flexible protocol firmware without implementing USB directly on the PIC MCU. Choose this architecture only after confirming interface timing, firmware boot behavior, and supply requirements from official documentation. The supplied evidence establishes 20 MHz operation, 7 KB Flash, 368-byte RAM, 16 I/O pins, and addressable USART, but it does not establish USB electrical compliance or package-level pin mappings.

Wichtigste Unterscheidungsmerkmale
- Seven-channel 10-bit ADC in the 28-QFN option (vs. PIC16F88-I/SO)
- Compact QFN construction for space-constrained boards (vs. PIC16F88-I/P)
- Three embedded serial options (vs. Generic non-PIC embedded-control candidates)
Designhinweise
Use the exact land pattern and exposed-pad requirements from Microchip's 28-QFN package drawing rather than treating it as a generic 28-pin footprint. Confirm pin 1 orientation, pad dimensions, solder-mask policy, and assembly paste design before fabrication. The supplied evidence identifies a 6 mm by 6 mm QFN but does not provide the official land-pattern dimensions; those values remain [DATA_NEEDED] and must not be estimated from a generic library footprint.
Partition analog and digital return paths carefully because the PIC16F88-I/ML combines seven 10-bit ADC inputs, 16 I/O pins, and three communication modes in a compact package. Place decoupling at the device supply pins, keep analog traces short, provide a quiet analog ground strategy, and keep switching-node and high-current return loops away from ADC inputs. Use the manufacturer pin-mux table to avoid assigning a peripheral signal to an unavailable or conflicting pin. Pin assignments were not supplied, so validate them in the official device documentation.
Do not approve a replacement based only on the /ML suffix or the PIC16F88 family name. Package pin count, pitch, body geometry, exposed pad, I/O mapping, analog channels, memory, and device-grade ordering codes must all match. PIC16F88-I/SO, -/SS, -/P, and -/PT variants use different package constructions, while the meaning of the T identifier in PIC16F88T-I/ML is not established by the supplied data. Treat them as related family members only until official documentation confirms board compatibility.
Establish the power architecture from verified operating-voltage and current limits before connecting sensors, communications transceivers, or actuators. The supplied material confirms integrated Flash, SRAM, EEPROM, ADC, USART, and synchronous serial resources but does not provide supply current, voltage tolerance, or absolute maximum ratings. Therefore no defensible power-dissipation or regulator-sizing estimate can be made. Verify those limits, identify all peripheral loads, and use the datasheet's decoupling and layout recommendations before schematic release.
Configure the internal 8 MHz oscillator or an external clock only after checking the timing configuration required by the firmware and selected communication interfaces. A 20 MHz maximum CPU rate does not mean every peripheral must or can be clocked identically. Use the manufacturer's configuration and timing guidance, preserve required oscillator setup time, and validate USART baud-rate error, SPI mode, I2C timing, and PWM behavior in hardware. The supplied excerpts do not contain detailed timing tables, so these values remain unverified here.
Compliance-Informationen
The supplied search results do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is treated as not applicable because the product is an industrial microcontroller rather than an explicitly identified automotive-qualified device; this does not substitute for an official qualification statement.
