PIC16F916T-I/SO - 14KB Flash 8-bit MCU with LCD Driver | Microchip
MPN： PIC16F916T-I/SO ✓ 啟用中PIC16F916T-I/SO 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/EEPROM/RAM), peripherals, and I/O on one die. The PIC16F916 family sits in the mid-range 8-bit PIC16 tier, below the 16-bit PIC24/dsPIC families and above baseline PIC10/PIC12 devices. Embedded 8-bit MCUs are widely used where deterministic behaviour, low power, and small footprint outweigh raw performance. The integrated LCD driver up to 60 segments distinguishes this part from generic PIC16F88x parts and removes the need for an external LCD controller.
Key features include 25 digital I/O pins, an internal oscillator, a 14-channel 8-bit ADC, one 8-bit timer plus one 16-bit timer, and nanoWatt technology that drops supply current into the microamp range during sleep. The I-grade -40C to +85C industrial temperature range supports consumer, appliance, and industrial user-interface applications. The 28-SOIC package offers an industry-standard 300-mil SOIC footprint compatible with hand-screened prototypes and automated assembly.
The PIC16F916 uses Microchip's enhanced mid-range 14-bit instruction core with a 2-stage pipeline, yielding 200 ns instruction execution at 20 MHz. On-chip peripherals are accessible through standard SFRs and are reused across the PIC16F91x family, easing code migration to PIC16F913/914/917 siblings with more memory and pins. The nanoWatt features include multiple idle/sleep modes, a low-power Timer1 oscillator, and software-controllable peripheral shutdown.
Typical applications include white goods and appliance front-panel displays, industrial metering with segmented LCD readouts, medical pumps with LCD menus, automotive interior modules with mid-density I/O, consumer devices with embedded UI, and battery-powered handheld instruments. The integrated LCD driver eliminates an external chip and reduces BOM cost in any user-interface design that previously needed a dedicated HT1621 or similar segment driver.
When designing with the PIC16F916T-I/SO, allocate at least 30% of program memory for code growth and reserve adequate RAM for the LCD segment buffer. Use MPLAB X IDE with XC8 compiler and PICkit 5 for development; the device is supported by Microchip's code-configurator (MCC) for rapid peripheral setup. Pin 1 is the MCLR/VPP/RA3 multi-function pin on the 28-SOIC, so do not pull it high through a weak resistor if in-circuit debugging is needed.

典型應用
PIC16F916T-I/SO 適用於 6 應用s: White Goods and Appliance User Interface, Industrial Metering with Segmented LCD, Medical Pump Front Panel Controller, Automotive Interior Modules, Consumer Devices with Embedded UI, Battery-Powered Handheld Instruments.
White Goods and Appliance User Interface
The PIC16F916T-I/SO fits white goods front-panel designs because its integrated 60-segment LCD driver, 25 I/O pins, and 14 KB Flash support capacitive-touch buttons plus multi-digit segment displays without a separate LCD controller. Its 2.0-5.5 V supply lets a 2-AA or 3-AA alkaline pack drive the display charge pump directly. Industrial -40 C to +85 C operation survives washing-machine and oven environments, and the 8-bit PIC core yields deterministic 200 ns response for rotary-encoder debouncing and switch-matrix scanning.
推薦
Industrial Metering with Segmented LCD
For electricity, gas, and water meters, the PIC16F916T-I/SO delivers the integrated LCD driver, 14-channel 8-bit ADC, and nanoWatt sleep current under 1 uA that battery-powered metering requires. The 14 KB Flash holds IEC 62053 metering algorithms and the 352-byte RAM buffers RMS samples. The 8-bit core's deterministic timing simplifies pulse-counting and tamper detection. The integrated charge pump lets the LCD run at 2 V supply, extending battery life on a single lithium-thionyl chloride cell.
推薦
Medical Pump Front Panel Controller
In medical infusion pumps and patient monitors, the PIC16F916T-I/SO provides the LCD segment driver for numeric and icon displays while leaving enough I/O for keypad scanning, audio alarms, and sensor feedback. The 20 MHz instruction rate supports real-time closed-loop PID control of pump stepper motors. The industrial -40 C to +85 C range covers equipment-warm-up conditions in hospitals. The 14 KB Flash stores fault logs and IEC 60601 alarm-rule tables.
推薦
Automotive Interior Modules
Climate-control head units, seat-position memories, and aftermarket instrument clusters can use the PIC16F916T-I/SO where a 25-I/O 8-bit MCU with an integrated LCD segment driver suffices. It supports CAN-friendly firmware via external transceivers and runs automotive-grade temperature variants through Microchip's -40 C to +125 C EEPROM-listed parts. The 8-bit core's deterministic timing suits button-matrix scanning and indicator-LED PWM at sub-100 us latency.
推薦
Consumer Devices with Embedded UI
Small consumer electronics like digital kitchen scales, Bluetooth speakers, and remote controls benefit from the PIC16F916T-I/SO's combined 14 KB Flash, integrated LCD driver, and 25 I/O. The 2 V minimum supply supports single-cell Li-ion or 2xAA battery packs without boost converters. The 8-bit core's small code size is ideal for power-constrained user-interface firmware that does not need a 32-bit MCU.
推薦
Battery-Powered Handheld Instruments
Portable multimeters, HVAC service tools, and industrial handheld scanners run on the PIC16F916T-I/SO's nanoWatt sleep current below 1 uA and integrated LCD charge pump. The 14 KB Flash stores unit-conversion tables, calibration curves, and USB-CDC command sets. The 20 MHz CPU performs 8-bit ADC oversampling for improved measurement resolution. The 28-SOIC package is easy to hand-rework on prototypes during firmware iteration.

主要差異化特點
- Integrated 60-segment LCD driver with charge pump (對比PIC16F88T-E/SS)
- 14 KB Flash plus 352 B RAM and 256 B EEPROM (對比PIC16F913T-I/SO)
- Industrial -40 C to +85 C operating range (對比PIC16F88T-E/SS)
設計說明
PIC16F916T-I/SO supply current drops below 1 uA in Sleep mode with the LCD charge pump enabled, and below 100 nA with the LCD off. Estimated: at 20 MHz, 5 V, full peripheral-active, the core draws about 8 mA. Use Sleep + Timer1 external 32.768 kHz crystal for low-duty-cycle metering firmware that wakes every second to refresh the LCD.
Place the 28-SOIC decoupling 100 nF capacitor within 3 mm of pins 19 (VDD) and 18 (VSS). For ICD, route MCLR/VPP/RA3 (pin 1) and RB6/RB7 (pins 26-27) to a 0.1 inch pitch header. Keep the LCD segment traces away from switching regulator or AC mains traces - the integrated LCD driver shares pin mux with analog inputs.
Do not program the MCLR pin as a digital output - it is shared with VPP programming voltage and pulling it low prevents ICSP. Configure pin 1 as MCLR with the CONFIG register bit MCLRE=1 if you need reset, or as RA3 digital I/O if you need an extra GPIO. Always set the WDT postscaler and LFINTOSC frequency bits explicitly; the factory default may not match your design.
