PIC16F916-I/ML - 8-Bit 20MHz Flash MCU | Microchip Technology
料号： PIC16F916-I/ML ✓ 量产中PIC16F916-I/ML 概述
An 8-bit microcontroller is a compact embedded controller that executes instructions from embedded Flash memory and operates directly on digital I/O, timers, serial interfaces, and other peripherals. The PIC16F916 belongs to the PIC16 family of flash-based CMOS microcontrollers with nanoWatt technology. Its 14 KB program memory is organized as 8K x 14 words, while its 352-byte RAM supports working variables and application data.
Key features include a 20 MHz maximum clock speed, an internal oscillator, PWM capability, UART, SPI, and I2C interfaces, plus 24 available I/O pins. The integrated LCD-driver-oriented family architecture and nanoWart power-management features make the device suitable for control systems that need a modest instruction set, deterministic peripheral operation, and low component count.
The PIC16 core uses a compact instruction set with 35 instructions to learn, and most instructions execute in a single cycle except branches. This structure supports straightforward control-loop implementation in appliances, instrumentation, industrial controllers, and small embedded products. The exposed pad in the QFN package supports thermal dissipation when the device dissipates power during sustained operation.
Typical applications include small motor and pump controllers, temperature-monitoring instruments, keypad interfaces, LED-signage controllers, battery-operated sensing nodes, and simple industrial automation modules. The device is particularly useful when a design needs multiple I/O lines, embedded Flash, and standard serial connectivity without the complexity of a higher-performance MCU.
When designing a PCB around the PIC16F916-I/ML, route the exposed pad to a thermal and ground copper area according to the package drawing. Confirm the oscillator configuration, programming interface, decoupling requirements, and I/O direction settings in the manufacturer datasheet before releasing the layout. This page combines device specifications, drop-in alternatives, application guidance, and practical design considerations for faster component selection.

典型应用
PIC16F916-I/ML 适用于 6 应用s: Temperature and Environmental Monitoring, Small Motor and Pump Control, Serial Gateway and Sensor Hub, LED Signage and Display Controller, Appliance and Household Control Board, Battery-Powered Sensing Node.
Temperature and Environmental Monitoring
The PIC16F916-I/ML fits compact sensing instruments because its 24 I/O pins can support digital sensors, alarm outputs, status indicators, and a local display interface while the 20 MHz CPU provides deterministic response. The 14 KB of Flash is suitable for calibration tables, filtering logic, and a modest user interface, while 352 bytes of RAM accommodates sensor sampling and a small working buffer. Use the I2C or SPI peripheral for compatible sensors and reserve UART output for configuration or diagnostics. Because the device is available in a 6 x 6 mm QFN, it also fits compact handheld instruments where board area is limited.
推荐
Small Motor and Pump Control
The PIC16F916-I/ML is appropriate for small motor, fan, or pump controllers where PWM is required but a high-performance control loop is unnecessary. Its PWM output can command a driver stage instead of carrying load current directly, and the 24 I/O pins provide room for limit switches, encoders, status LEDs, and interlock signals. The 20 MHz maximum clock gives the firmware headroom for closed-loop timing, debouncing, and fault handling. A 352-byte RAM budget suits compact supervisory logic, although motor-current protection and electrical isolation remain functions of the external driver stage.
推荐
Serial Gateway and Sensor Hub
The PIC16F916-I/ML works well as a compact protocol-conversion node because it combines UART, SPI, and I2C in one device. A gateway can poll sensors over I2C, configure an external transceiver over SPI, and expose status through UART, all while the 14 KB Flash holds the protocol state machine and configuration table. The 24 available I/O pins also allow link selection, reset control, and fault indication. This mixed-peripheral combination reduces the need for an additional interface IC and keeps the design suitable for embedded industrial or instrumentation modules.
推荐
LED Signage and Display Controller
The PIC16F916-I/ML can supervise LED matrices, status panels, and small illuminated signs where multiple outputs and low-cost control are more important than maximum processing throughput. PWM channels support dimming or effect generation, while SPI is suitable for driving external display and LED-driver devices. The 14 KB program memory can hold animation tables, schedules, and diagnostic routines, and 352 bytes of RAM is sufficient for a short frame buffer or button-state map. The compact QFN package also helps when the controller must sit behind a display panel in a thin enclosure.
推荐
Appliance and Household Control Board
The PIC16F916-I/ML is suited to household appliance controllers that coordinate relays, sensors, displays, and serial configuration tools. Its 24 I/O pins reduce the need for external logic, and the PWM capability can support indicator dimming or selected actuator drive. The 8-bit architecture and 35-instruction learning requirement simplify firmware maintenance for cost-sensitive embedded products. Firmware can implement button handling, motor timing, fault codes, and service-mode diagnostics within the 14 KB Flash limit, while the industrial ordering suffix supports designs targeting extended-temperature environments.
推荐
Battery-Powered Sensing Node
The PIC16F916-I/ML supports small battery-powered monitoring nodes where a timer-driven measurement cycle and low standby activity are more important than continuous processing. Its internal oscillator eliminates the need for an external crystal when the timing tolerance is acceptable, and the mixed UART, SPI, and I2C peripherals allow a radio or sensor module to be connected without a separate interface bridge. The 352-byte RAM is adequate for sampled values and packet staging, while the 14 KB Flash can hold sleep routines, radio-control logic, and configuration. Validate the final power budget against the selected external radio and sensor because system idle current dominates the MCU contribution.

关键差异点
- Direct same-device ordering configuration （对比 PIC16F916-E/ML)
- Integrated mixed serial connectivity （对比 PIC16F913-I/ML)
- Compact exposed-pad footprint （对比 PIC16F916-E/ML)
设计说明
Assign the QFN exposed pad according to the manufacturer package drawing, and provide a low-impedance ground connection and thermal copper area. Place input bypass capacitance close to the device supply pins and route sensitive sensor or communications lines away from switching nodes. The 6 x 6 mm footprint leaves little assembly margin, so verify land-pattern dimensions and paste stencil recommendations against the current package drawing before fabrication.
Budget the complete power path for the MCU and its external loads, including I/O drive current and any radio or sensor connected to the board. The device offers an internal oscillator and nanoWart technology, but external peripherals often dominate sleep-mode consumption. Confirm supply voltage limits, peripheral current, and average duty cycle in the manufacturer datasheet, then size the regulator and local bypass network around those conditions.
Do not treat a similar PIC16 family member as an automatic drop-in replacement. The 24 I/O count does not mean that every package lead is user I/O, and unused or dedicated pins can differ between related devices. Before substitution, compare the complete pin-description table, memory limits, peripheral multiplexing, oscillator configuration, programming setup, and thermal requirements. Revalidate the application after any firmware or board-level change.
合规信息
The manufacturer product page identifies the PIC16F916 family as in production. Compliance declarations are not stated in the available product listings, so the relevant declarations and ordering information should be confirmed with the manufacturer before release.
