PIC16F916-I/SP - 8-Bit 20MHz 14KB Flash MCU w/ LCD | Microchip
MPN: PIC16F916-I/SP ✓ Hoạt độngPIC16F916-I/SP Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), peripherals and I/O on one die. The PIC16F916 belongs to the PIC16 mid-range family (PIC16 -> 8-bit MCU -> microcontroller -> embedded IC) and adds an integrated LCD driver capable of driving up to 28/32/36 segments depending on package, which removes the need for an external LCD controller in HMI designs.
Key differentiating features include nanoWatt power management for sleep currents as low as the nA range, an internal oscillator selectable from 31 kHz to 8 MHz, 24 digital I/O lines with individual direction control, a 10-bit ADC with up to 11 channels, and Capture/Compare/PWM (CCP) modules. The 28-pin SPDIP package is breadboard-friendly, simplifying prototyping and field-replacement workflows.
Architecturally the PIC16F916 uses a Harvard RISC core with only 35 single-word instructions, most executing in a single 200 ns instruction cycle at 20 MHz. The integrated LCD module supports static, 1/2, 1/3 and 1/4 duty cycles with a charge-pump option, eliminating external bias generation and reducing BOM cost for human-machine interface (HMI) products.
Typical applications include white-goods front panels, thermostat and HVAC user interfaces, industrial control keypads with LCD readout, metering and instrumentation displays, and consumer electronics requiring an integrated segmented display. The 20 MHz core, 14 KB Flash and 24 I/O make it well suited to mid-complexity control with HMI.
When designing with the PIC16F916, configure unused I/O as outputs (not inputs) to avoid floating-pin current, observe the Vdd rise-time specification during in-circuit serial programming (ICSP), and place the device decoupling capacitor (0.1 uF) within 5 mm of Vdd. For LCD designs, the bias-generation capacitors (typically 0.1 uF to 1 uF) are mandatory; omitting them produces ghost segments.

Ứng dụng tiêu biểu
PIC16F916-I/SP phù hợp cho 6 Áp dụngs: White-Goods Front Panel Controller, Thermostat and HVAC User Interface, Industrial Metering and Instrumentation Display, Consumer Electronics with Segment Display, Medical Monitoring with Display, Automotive Interior HMI (Non-Safety).
White-Goods Front Panel Controller
The PIC16F916-I/SP's integrated segmented LCD driver and 14 KB Flash make it ideal for washing-machine, dishwasher and refrigerator front-panel controllers. The 28-pin SPDIP supports up to 28 LCD segments for time/temperature/program readouts without an external LCD controller, and the nanoWatt sleep modes let the MCU idle below 1 uA between key presses, satisfying ENERGY STAR standby budgets.

Thermostat and HVAC User Interface
Wall thermostats require an LCD for setpoint/temperature readout and a small MCU to run the PID control loop. The PIC16F916-I/SP's integrated LCD charge pump removes the need for a negative bias supply, the 10-bit ADC reads thermistor sensors with adequate resolution, and the 24 I/O lines drive keypad matrix, triac outputs and communication UART. The -40C to +85C industrial grade covers conditioned spaces and equipment closets.
Được đề xuất
Industrial Metering and Instrumentation Display
Electricity meters, water meters and gas meters need a segmented LCD readout plus non-volatile EEPROM for accumulated usage. The PIC16F916-I/SP provides 256 bytes of EEPROM with 1M-cycle endurance for billing counters, 14 KB Flash for tariff schedules, and the LCD module drives up to 28 segments for kWh/MWh/cost displays. The 20 MHz core executes the metering calculation and LCD refresh concurrently.

Consumer Electronics with Segment Display
Coffee makers, microwave ovens, rice cookers and audio products commonly use PIC16F916-I/SP because the LCD driver eliminates a separate controller IC, the 14 KB Flash fits user-interface state machines, and the 28-pin SPDIP through-hole package simplifies factory assembly. The PIC16 RISC core runs the keypad scan, sensor reads and LCD refresh on a single interrupt-driven loop.

Medical Monitoring with Display
Non-critical medical devices such as blood-pressure cuffs, glucometers and pulse-oximeters use the PIC16F916-I/SP to drive the segmented LCD readout while running ADC measurements. The 10-bit ADC delivers the resolution needed for vital-signs sensors, the 24 I/O lines connect to buttons and pump drivers, and the nanoWatt sleep modes extend battery life in portable form factors. Use the PIC16F916-E/SP for extended-temperature applications.

Automotive Interior HMI (Non-Safety)
For non-safety automotive interior modules such as HVAC control heads and seat-adjustment panels, the PIC16F916-I/SP provides the segmented LCD and button-matrix I/O needed for the HMI. Designers targeting AEC-Q100 qualified systems should migrate to PIC16F equivalent parts in the automotive PIC portfolio; the -I/SP industrial grade is suited to cabin environments, and the wide -40C to +85C range handles under-dash thermal stress.

Ghi chú thiết kế
Place the 0.1 uF Vdd decoupling capacitor within 5 mm of the Vdd pin (pin 20) with a short, wide trace to the Vss pin (pin 19). For the LCD module, install the charge-pump flying capacitors (typically two 0.1 uF to 1 uF ceramic) as close to the VLCD and CAP pins as possible; long traces cause ghost segments or reduced contrast. Keep digital signal traces away from the SEG/COM lines that route to the LCD glass.
Configure all unused I/O pins as outputs (not inputs) - floating inputs draw mA-range supply current and can shift the analog reference. During ICSP programming, ensure the MCLR pull-up (typically 10 kohm) does not prevent entry into programming mode; some debuggers require MCLR to be driven low externally. Vdd rise-time at power-up must be slower than the BOR specification; very fast risetimes can prevent clean reset.
When using the internal oscillator, leave OSC1/OSC2 floating or terminate them with short traces; long traces act as antennas and couple noise into the analog channels. For ADC measurements, place the analog reference bypass capacitor within 5 mm of Vref, average 16 or more ADC samples to reduce noise, and avoid switching high-current outputs during ADC conversions to minimize digital-coupling artifacts on the analog readings.
