PIC16F916-E/SS - 8-Bit 20MHz 14KB Flash MCU w/ LCD | Microchip
MPN: PIC16F916-E/SS ✓ Hoạt độngPIC16F916-E/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O into one device. The PIC16F916 belongs to the PIC mid-range 8-bit family — within the broader hierarchy: PIC16F91X -> PIC16F family -> PIC16 -> PIC microcontrollers -> 8-bit microcontrollers -> microcontrollers -> embedded processors -> semiconductors. The mid-range core uses a 14-bit instruction word with a 35-instruction RISC set and executes most instructions in a single 200 ns cycle at 20 MHz, balancing code density, deterministic interrupt response, and ease of programming.
Key features include 25 mA source/sink I/O current for direct LED drive, internal 32 kHz to 8 MHz oscillator eliminating external crystals in many designs, two 8-bit timers (TMR0, TMR2), one 16-bit timer (TMR1), an extended watchdog timer (EWDT), Brown-Out Reset (BOR) with software control, In-Circuit Serial Programming (ICSP), and a programmable Low-Voltage Detect (LVD). The 28-SSOP /E temperature suffix indicates an extended industrial operating range of -40C to +125C.
The PIC16F916 combines a RISC Harvard-bus CPU with separate program and data buses for predictable single-cycle instruction timing, and the integrated LCD driver supports static, 1/2, 1/3, and 1/4 multiplexed LCDs with selectable bias, removing the need for an external LCD controller in segment-display designs. nanoWatt Technology provides multiple power-managed modes (Run, Idle, Sleep) that drop quiescent current into the microamp range for battery-powered applications.
Typical applications include battery-powered consumer appliances with LCD displays, industrial control panels, metering equipment, white-goods user interfaces, security-system keypads, and any cost-sensitive embedded design requiring segment-LCD visualization without an external driver. The wide 2.0V-5.5V operating range supports both 3.3V and 5V designs from a single part.
When designing with the PIC16F916-E/SS, route the LCD segment pins with proper bias-capacitor placement on SEG/COM lines, and use ICSP with a 2-wire programming interface for field firmware updates. Choose the -E (extended) temperature grade for automotive or industrial enclosures above +85C, while the -I (industrial) grade suffices for commercial products at 0C to +85C.

Battery-Powered Metering with Segment LCD
The PIC16F916-E/SS is purpose-built for battery-driven metering products that display readings on segment LCDs. Its integrated 60-segment LCD driver eliminates the need for an external LCD controller, while nanoWatt Technology drops Sleep current to the nanoamp range, enabling multi-year coin-cell operation. The 14 KB Flash accommodates meter calibration tables, while 352 B SRAM and 256 B EEPROM handle rolling consumption logs. With 2.0V-5.5V operation, the part runs directly from 2x AA alkaline cells or a single lithium primary, matching the voltage profile of gas, water, and heat meters.

White-Goods and Appliance User Interface
The PIC16F916-E/SS is ideal for washing-machine, dishwasher, and oven control panels where a multi-segment LCD shows time, temperature, and program status. The integrated LCD driver supports static, 1/2, 1/3, and 1/4 multiplex modes with selectable bias, allowing designers to drive cost-effective TN displays without an external charge-pump or controller. Its 25 mA source/sink I/O drives LEDs and buzzer transducers directly, while the 5-channel 10-bit ADC reads NTC temperature sensors. The -40C to +125C extended range covers oven-door and laundry-room environments.

Industrial Control Panels and HMIs
The PIC16F916-E/SS serves industrial control panels and small HMIs that combine push-button inputs with a segment-LCD readout. The 24 I/O at 25 mA source/sink directly drive relay coils, opto-isolators, and status LEDs without buffer transistors. ICSP enables field firmware updates via a 2-pin header, and the extended -40C to +125C temperature grade suits outdoor enclosures and unheated cabinets. The programmable LVD and BOR protect against brown-out in 24V industrial bus systems stepped down to 5V, ensuring reliable reset behaviour during power dips.

Consumer Remote Controls with LCD
The PIC16F916-E/SS enables feature-rich AV remote controls with a multi-segment LCD for menu navigation, channel guides, and device status. Its low Sleep current under nanoWatt Technology lets a single coin cell last the shelf life of the remote. The 5-channel 10-bit ADC reads IR-remote ambient-light sensors and battery voltage, while ICSP allows mass-production programming. The 35-instruction RISC core simplifies coding of state-machine-based menu logic, and 14 KB Flash holds custom UI fonts.

Ghi chú thiết kế
Place the VDD decoupling capacitor (0.1 uF ceramic) within 5 mm of pins 10 and 20, with a wide ground trace to pin 9/19. The PIC16F916 has two VDD/VSS pairs on the SSOP-28, both of which must be connected to avoid logic errors during inrush. Add a 10 uF bulk capacitor near the regulator to supply the 25 mA peak I/O source current when driving LEDs or relay coils simultaneously.
Configure the BOR and LVD via CONFIG registers to match your supply profile. For 5V USB or industrial buses, set BOR at 4.0V and LVD at 4.2V; for 3.3V coin-cell designs, set BOR at 2.4V and disable LVD. nanoWatt Sleep drops current to the nanoamp range while keeping RAM and peripherals alive — use the WDT wake-up for periodic sampling at 1 Hz in metering applications.
Route LCD SEG and COM traces with minimal cross-over and keep them away from fast-switching digital lines (PWM, oscillator) to avoid ghost-segment artefacts. Place the VLCD bias capacitors (typically 0.1 uF) close to the COM pins and use a star-ground connection back to VSS. For 1/3 or 1/4 multiplex modes, allocate one capacitor per COM line and ensure trace widths are similar across all segments to equalize charge transfer.
Do not confuse the -I (industrial) and -E (extended) temperature grades when ordering — they share the same datasheet but only the -E grade is qualified for -40C to +125C. Also note that pin 5 is multiplexed with MCLR; if MCLR is enabled in CONFIG, the pin cannot be used as RA3. Finally, the internal oscillator accuracy is typically +/-2% at 25C and +/-5% across temperature, so use an external crystal for UART baud-rate-sensitive designs.
