PIC16F690T-I/SO 概要
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, digital I/O, and peripherals on one integrated circuit. The PIC16F690 MCU family is intended for compact embedded-control tasks in which deterministic control, serial communication, analog measurement, and low-cost PCB assembly are more important than high processing bandwidth. Within the product hierarchy, it is a microcontroller, then an embedded processor and semiconductor.
Key verified features include 20 MHz operation, 7 KB Flash memory, 4K x 14-word organization, 18 I/O resources, and on-chip EEPROM Data Memory according to Microchip's family page. The target suffix denotes the temperature and packaging configuration, while the verified catalog listing identifies the physical device as 20-SOIC. The available family data also identifies a 2.0 V to 5.5 V operating range. Detailed RAM size, ADC characteristics, timer resources, and current consumption are not included in the supplied records and are therefore not inferred here.
The PIC16F690 uses Microchip's mid-range x14 instruction architecture, an 8-bit RISC-style execution model suitable for compact control firmware. Its integrated serial and analog capabilities make it practical to consolidate functions that otherwise require several discrete components. Because firmware, peripheral configuration, pin multiplexing, and electrical limits must be checked against the official device documentation, existing PIC16F690 designs should be revalidated before substitution.
Typical uses include compact industrial controllers, appliance controls, sensor-interface nodes, LED and lighting controllers, communication modules, and low-power embedded products. The 20-pin SOIC package is useful where a narrow, conventional surface-mount footprint and broad assembly familiarity are priorities. The family operating range supports systems built around low-voltage sensors and embedded control logic, subject to the exact pin and electrical limits in the manufacturer documentation.
For PCB design, preserve the package outline and pad layout defined for the 20-pin SOIC variant, route decoupling close to the supply pins, and confirm oscillator, programming, and serial-interface connections against the official pinout. If a replacement is considered, verify package pin compatibility and verify all device functions; a similar clock rating alone does not prove drop-in equivalence.
This page combines verified manufacturer and distributor facts, source-linked design guidance, and practical replacement constraints beyond a basic catalog listing. Pricing and availability remain time-sensitive, so the cited distributor records should be checked before purchasing or committing a production design.

主な用途
PIC16F690T-I/SO の用途: 6 件s: Compact Industrial Control Node, Sensor and Measurement Interface, Appliance and Embedded Product Controller, LED and Lighting Controller, Battery-Powered Embedded Sensor Node, Communication and Protocol Interface.
Compact Industrial Control Node
The PIC16F690T-I/SO fits compact control nodes because its 20 MHz clock, 7 KB Flash, 18 I/O resources, and on-board EEPROM provide enough room for local sequencing, status handling, and configuration storage. It can monitor discrete inputs and drive relays, indicators, or actuators through its I/O while retaining serial connectivity. The 20-SOIC footprint also simplifies adoption in a narrow surface-mount design. Before layout release, confirm the exact I/O pin functions, supply decoupling, reset behavior, and peripheral configuration in Microchip's documentation.
おすすめ
Sensor and Measurement Interface
PIC16F690T-I/SO is appropriate for a sensor-interface board that needs local ADC measurement, digital I/O, and serial reporting. Its verified 8-bit architecture and 20 MHz clock support straightforward sampling, filtering, thresholding, and communication tasks, while the family's 2.0 V to 5.5 V operating range can support low-voltage sensor systems. Use the MCU for signal conditioning decisions and configure the ADC, I2C, SPI, or UART as required. Exact converter accuracy, sampling behavior, and analog limits must be taken from the official datasheet.
おすすめ
Appliance and Embedded Product Controller
The PIC16F690T-I/SO can serve as the central controller in a compact appliance, fan controller, pump controller, or other embedded product. Its 7 KB Flash provides room for a dedicated control program, while 18 I/O resources support keys, indicators, switches, sensors, and output stages. The 2.0 V to 5.5 V family range can simplify low-voltage power partitioning. Design around the verified 20-SOIC footprint and account for relay or load transients, grounding, and supply-noise isolation.
おすすめ
LED and Lighting Controller
PIC16F690T-I/SO is suitable for compact LED and lighting control because the device combines programmable flash, 18 I/O resources, timers, and serial interfaces in a 20-SOIC package. It can implement button logic, dimming schedules, status patterns, and communication with a host controller. The 20 MHz clock supports deterministic timing for common low- and medium-rate lighting functions. Choose output transistors or driver circuitry to match LED current, and verify PWM-related timing and pin multiplexing in the device documentation before production.
おすすめ
Battery-Powered Embedded Sensor Node
The PIC16F690T-I/SO can be used in a small battery-powered sensor node where periodic measurement, low pin count, and local serial communication matter. Its nanoWatt technology designation indicates a low-power design focus, while the 2.0 V to 5.5 V family range supports low-voltage systems. The MCU can wake from a duty cycle, read sensors, transmit results, and return to a low-power state. Actual sleep current, active current, wake-up time, and analog accuracy are not present in the supplied data and must be measured or sourced from the datasheet.
おすすめ
Communication and Protocol Interface
PIC16F690T-I/SO can act as a compact protocol gateway or peripheral controller because the verified feature set includes I2C, SPI, UART, 20 MHz operation, and programmable Flash. It can bridge sensor registers, configure another device, and expose status over a host serial link. The small 20-SOIC package helps when board area is limited, while 18 I/O resources support indicators and handshake signals. Verify electrical levels, baud-rate limits, peripheral pin multiplexing, and timing margins against the official device data.

設計ノート
Design the board around the verified 20-SOIC package and preserve the manufacturer-recommended land pattern rather than substituting a generic SOIC footprint by visual similarity alone. Confirm pin numbering, pin 1 orientation, pad dimensions, solder-mask clearance, and copper keepouts from the official package drawing. Route the supply and ground connections first, then place decoupling capacitors close to the relevant device pins to minimize loop area.
The verified family operating range is 2.0 V to 5.5 V, but the usable range depends on the selected clock, peripherals, I/O levels, and load current. Calculate the supply margin for startup, regulator tolerance, transient response, and the highest required bus voltage. Do not power I/O pins above the device limits; use level translation or a compatible interface when external logic uses a different voltage domain.
For I2C, SPI, UART, or other external interfaces, keep traces short where possible and provide the pull-ups, termination, and grounding required by the specific protocol. The supplied records do not establish exact timing or output-impedance values, so consult the manufacturer datasheet before setting edge-rate or bus-capacitance assumptions. Leave test points or programming access where they will not compromise antenna, isolation, or high-voltage clearances.
Do not treat PIC16F690T-I/SO, PIC16F690-I/SO, and PIC16F690-E/SO as interchangeable merely because the package and family name are similar. Suffix codes can affect temperature grade, qualification, or ordering designation. Verify the ordering table, pin configuration, memory map, timing limits, and programming requirements, and confirm that the replacement is sourced from an authorized channel before releasing a production build.
コンプライアンス情報
The supplied search results do not provide a verified compliance declaration for the target MPN. RoHS, REACH, halogen-free, conflict-minerals, and qualification status must be confirmed from current Microchip documentation or an authorized distributor record.
