PIC16F916-I/SS - 8-Bit 20MHz Flash MCU | Microchip Technology
MPN: PIC16F916-I/SS ✓ Hoạt độngPIC16F916-I/SS Tóm tắt
A microcontroller is a programmable semiconductor that integrates a CPU core, Flash program memory, data memory, timers, communication peripherals, and I/O ports into one device. Within the product hierarchy, the PIC16F916-I/SS is an 8-bit MCU, part of the PIC16 family, and belongs to the broader embedded-controller and semiconductor categories. Its compact package supports cost-sensitive designs where space and power consumption matter.
Key characteristics include a maximum clock speed of 20 MHz, approximately 200 ns instruction execution, and an instruction set described as containing 35 single-word instructions. The device provides 14 KB of Flash program memory, 25 I/O pins, an integrated LCD driver, and nanoWatt power-management capabilities. Together, these features support responsive control loops, direct segment display operation, and compact embedded products.
The PIC16 core uses a compact instruction architecture intended to simplify firmware development while retaining dedicated hardware for common control tasks. Flash memory permits in-system reprogramming, while the LCD-driver resources can reduce the component count in meter, instrument, appliance, and industrial-panel designs. The manufacturer identifies the PIC16F916 as an in-production device and supports development with the MPLAB toolchain and PICkit in-circuit debugging products.
Typical uses include blood-pressure monitors and other compact medical-control products, LCD-equipped instrumentation, household appliances, industrial controls, sensor interfaces, and low-power embedded equipment. The 25 available I/O pins provide connections for sensors, buttons, displays, actuators, and communication peripherals while keeping the board area small.
Designers should verify each I/O pin's multiplexed function, timing, and electrical limits against the manufacturer datasheet before assigning LCD segments or peripherals. Decoupling, programming access, oscillator configuration, and unused-pin treatment should follow the device's recommended circuit and PCB guidelines.
This product page combines the manufacturer device specifications with practical pin, application, replacement, and design guidance. It is intended to accelerate engineering selection while making the differences between electrically similar PIC16F91x devices explicit.

Ứng dụng tiêu biểu
PIC16F916-I/SS phù hợp cho 6 Áp dụngs: Blood Pressure Monitor Control, LCD Instrument Panel, Industrial Sensor Interface, Household Appliance Controller, Low-Power Embedded Equipment, Programmable Control Module.
Blood Pressure Monitor Control
The PIC16F916-I/SS fits compact blood-pressure monitor controllers because it combines an 8-bit PIC16 core, 20 MHz maximum operating speed, 14 KB of Flash, and 25 I/O pins with an integrated LCD driver. The MCU can coordinate pressure-sensor sampling, valve or pump control, button input, and display-segment multiplexing while maintaining a compact 28-pin SSOP footprint. Its approximately 200 ns instruction execution supports responsive sequencing of measurement and user-interface tasks. The LCD resources can reduce the need for an external segment driver, although the selected glass, segment map, and shared-pin requirements must be validated before layout release.

LCD Instrument Panel
PIC16F916-I/SS is suitable for LCD-based instrument panels where a dedicated display driver would add cost and board area. Its integrated LCD driver works with 25 I/O pins in a 28-pin SSOP package, allowing engineers to connect segment and common-display lines alongside switches, indicators, and measurement inputs. The 20 MHz maximum CPU speed and approximately 200 ns instruction time provide practical headroom for display refresh, keypad scanning, and control logic. Because display multiplexing can consume pins shared with general-purpose I/O, designers should build the required segment map and pin-allocation matrix before committing the PCB footprint.
Được đề xuất
Industrial Sensor Interface
The PIC16F916-I/SS can serve as the central controller in a compact industrial sensor interface because it provides 25 I/O pins, 14 KB of Flash, and a 20 MHz maximum operating frequency in a surface-mount SSOP package. Engineers can use the I/O resources for digital sensors, alarm outputs, status indicators, and communication peripherals while retaining sufficient program memory for acquisition, filtering, diagnostics, and configuration logic. The nanoWatt feature supports power-conscious designs, but peripheral clocks, idle modes, and wake-up behavior must be configured carefully to achieve the intended low-power behavior in the finished product.

Household Appliance Controller
PIC16F916-I/SS works well in appliance-control boards that combine a segment display with switches, sensors, relays, and status outputs. Its 8-bit PIC16 architecture and approximately 200 ns instruction execution support responsive user-interface and state-machine operation, while 14 KB of Flash provides space for product logic and configuration handling. The 28-pin SSOP package reduces board footprint, and the integrated LCD driver simplifies common appliance displays. Engineers should budget decoupling near the supply pins, provide the required programming access, and confirm that high-energy loads are isolated from sensitive MCU and display connections.
Được đề xuất
Low-Power Embedded Equipment
PIC16F916-I/SS can support compact, power-conscious embedded equipment because it combines nanoWatt technology with an 8-bit core, Flash program memory, and a 25-I/O-pin interface. The device is suitable for battery-assisted instruments, portable monitors, and control products that periodically wake to sample inputs, update a display, or update stored settings before returning to a low-power state. Actual battery life depends on the selected clock, active duty cycle, analog circuitry, LCD bias requirements, and peripheral configuration. Validate sleep currents, wake-up sources, brownout behavior, and display power consumption at the system level rather than relying only on nominal microcontroller specifications.
Được đề xuất
Programmable Control Module
PIC16F916-I/SS is appropriate for a compact programmable control module that must combine application firmware with external inputs and outputs. Its 14 KB Flash allocation supports structured control code, 25 I/O pins support peripheral expansion, and the 20 MHz maximum clock permits responsive timing in product designs. The same MCU can manage a display, acquire sensor data, and operate actuators without requiring a separate processor. Firmware development is supported by the Microchip Technology MPLAB environment and compatible PICkit tools, allowing the same hardware platform to be reused across several product variants with different display maps, sensor combinations, or control policies.

Ghi chú thiết kế
Use the 28-pin SSOP land pattern and pin-1 orientation defined by the Microchip Technology package drawing. Place the required bypass capacitors close to VDD and VSS pins, and preserve access to the programming interface. Because SSOP leads are closely spaced, verify solder mask, paste volume, and assembly clearances against the recommended footprint before releasing the PCB files.
Build the LCD and general-purpose I/O allocation before routing the board because some display functions can share pins with other peripherals. Maintain a pin-function matrix that records the selected oscillator pins, programming connections, segment outputs, commons, and application I/O. This prevents a late display-map change from forcing component placement or track modifications.
Calculate the average and peak supply demand before selecting the regulator and bulk capacitance. Decouple the MCU supply locally, route return current through the ground plane, and keep switching-regulator and high-current output paths away from LCD and sensitive input traces. If nanoWatt operation is required, measure sleep current in the finished assembly because external circuitry can dominate the MCU's contribution.
Do not treat every 28-pin SSOP PIC16 variant as an automatic substitution. Confirm the exact memory capacity, peripheral set, pin multiplexing, temperature grade, configuration bits, and package drawing. After changing variants, rebuild the firmware with the correct device configuration and retest startup, LCD output, timing, reset behavior, programming, and unused-pin states.
