PIC16F913-I/SS Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash/ROM), volatile working memory (RAM), and a configurable set of digital and analog peripherals on one die. Within the broader semiconductor hierarchy, the PIC16F913 sits in the 8-bit MCU category under "microcontrollers" and "embedded controllers," with the LCD driver and nanoWatt power management positioning it in the human-machine interface (HMI) and low-power product tier.
Key features include up to 60 LCD segments (driven through dedicated VLCD bias and COM/SEG pins), nanoWatt Technology for reduced sleep current, a hardware Brown-Out Reset (BOR) with software control, In-Circuit Serial Programming (ICSP), and 25 mA source/sink I/O capable of directly driving LEDs or relays. The timer subsystem combines an 8-bit Timer0/Timer2, a 16-bit Timer1, and an extended Watchdog Timer (EWDT) for safety-critical applications.
Architecturally, the device uses a 14-bit instruction word, Harvard bus (separate program/data paths), and a 35-instruction RISC-style instruction set, which delivers deterministic timing and efficient C-compiler code density. The internal oscillator block supports 31 kHz to 8 MHz without external crystals, lowering BOM cost for cost-sensitive HMI designs.
Typical applications include white-goods front panels, thermostat displays, battery-powered metering, medical-device LCDs, industrial sensor readouts, and consumer appliances where a glass-segment LCD replaces an OLED for sunlight readability or ultra-low quiescent current. The wide 2.0V-5.5V range further suits multi-cell battery and USB-powered products.
Designers should reserve board space for the VLCD charge-pump or external bias resistors, place a 0.1 uF decoupling capacitor within 5 mm of VDD, and verify ICD/ICSP header placement before PCB layout is finalized for production. The "-I" suffix denotes the industrial -40C to +85C temperature grade suited to outdoor and factory-floor equipment.

Typical Applications
PIC16F913-I/SS is suitable for 6 applications: White-Goods Front-Panel HMI, Thermostat and HVAC Controller, Battery-Powered Metering and Utility Endpoints, Medical and Wellness Handheld Devices, Industrial Sensor Readout Modules, Consumer Appliance and Audio Control Panels.
White-Goods Front-Panel HMI
The PIC16F913-I/SS drives segment LCDs on washing-machine, dishwasher, and refrigerator front panels. Its on-chip 60-segment LCD controller eliminates external display-driver ICs, while nanoWatt Technology keeps standby current under 1 uA so appliances meet ENERGY STAR idle budgets. The 2.0V-5.5V supply range accepts the universal 3.3V or 5V rails typically generated by a small switch-mode PSU. Designers route SEG/COM lines directly to the glass, use the internal charge pump for VLCD, and place a 0.1 uF decoupling capacitor within 5 mm of VDD. Compared with character LCDs driven by a separate HD44780 controller, the integrated approach saves 3-5 mm of PCB space and 2-3 mA of bias current.
Recommended
Thermostat and HVAC Controller
Programmable thermostats benefit from the PIC16F913-I/SS's wide -40C to +85C industrial temperature range, integrated LCD driver, and Brown-Out Reset with software control. The MCU reads temperature sensors via ADC, drives a 7-segment or dot-matrix glass LCD for the readout, and runs a low-power sleep loop between samples. With the internal 32 kHz LF oscillator and nanoWatt sleep, average supply current stays well below 10 uA on two AA cells, supporting multi-year battery life. The 35-instruction RISC core also delivers deterministic loop timing that simplifies the PID control code for the HVAC relay or TRIAC output stage.
Recommended
Battery-Powered Metering and Utility Endpoints
The PIC16F913-I/SS is a strong fit for water, gas, and electricity meters that display cumulative consumption on a segmented glass LCD. Its hardware BOR with software control prevents corrupted EEPROM writes when the battery nears end-of-life, and the 256-byte EEPROM provides non-volatile storage for tariff and calibration data without external memory. The integrated LCD driver supports 1/3 bias multiplex up to 60 segments, well-matched to typical 6-digit meter displays with status icons. Running from a single lithium primary cell, the MCU's nanoWatt sleep draws under 1 uA, enabling 10+ year field deployment.
Recommended
Medical and Wellness Handheld Devices
The PIC16F913-I/SS powers compact medical handhelds such as blood-pressure cuffs, glucose meters, and pulse oximeters where a glass-segment LCD is preferred for sunlight readability and lower cost than OLED. The industrial -40C to +85C operating range supports clinical and home environments, and the 7 KB Flash accommodates the device firmware plus calibration constants in 256 bytes of data EEPROM. The 25 mA source/sink I/O directly drives piezo buzzers and LED status indicators without buffer transistors. Combined with nanoWatt sleep, the device meets IEC 60601 low-leakage targets on battery operation.
Recommended
Industrial Sensor Readout Modules
Factory-floor sensor heads and process transmitters benefit from the PIC16F913-I/SS's industrial temperature grade and integrated LCD for local readout of pressure, flow, or level values. The 24 GPIO with 25 mA drive can directly switch 4-20 mA loop transistors or relay coils, eliminating driver stages. The Extended Watchdog Timer (EWDT) provides the failsafe behavior required in unattended industrial nodes, while hardware BOR with software control prevents brown-out corruption on noisy 24V-derived rails. The same SSOP-28 footprint as PIC16F883-I/SS lets engineers reuse PCBs across LCD and non-LCD variants.
Recommended
Consumer Appliance and Audio Control Panels
The PIC16F913-I/SS drives segmented LCDs and keypads on microwave ovens, coffee machines, audio mixers, and small kitchen appliances. Its 35-instruction RISC core runs efficient state-machine code for menu navigation, while the integrated LCD controller simplifies the BOM by replacing an external HT1621 or similar segment driver. Hardware ICSP lets production lines update firmware without removing the chip, accelerating time-to-market for feature revisions. With internal oscillator, no external crystal is needed, freeing board space for the keypad matrix and reducing component cost below $0.30 USD in volume.

Key Differentiators
- Integrated 60-segment LCD driver (vs PIC16F883-I/SS)
- Doubled Flash without PCB changes (vs PIC16F914-I/SS (upgrade path))
- nanoWatt Technology and wide voltage range (vs PIC16F913T-I/SS)
- Industrial -40C to +85C grade as standard (vs PIC16F913-E/SS (extended grade))
Design Notes
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 27) and a bulk 10 uF capacitor on the same rail. The internal 32 kHz-8 MHz oscillator draws less than 20 uA in low-power LF mode but can momentarily exceed this during PLL lock acquisition. For battery applications, gate the LCD charge pump with a software-controlled GPIO to disable it during deep sleep, reducing IqIC below 1 uA per the Microchip nanoWatt datasheet figures.
Route SEG and COM LCD signals as parallel traces of equal length to within 1 cm to maintain segment contrast uniformity. Add a ground guard trace between LCD lines and adjacent digital lines to reduce crosstalk on long flex cables. Keep the VLCD charge-pump capacitor (typically 1 uF X7R) within 3 mm of the VLCD pin, and reserve board space for an external potentiometer on VLCD3 if fine contrast adjustment is needed across temperature.
The PIC16F913 has no on-chip ADC. Designs that need analog sensor reads must use the comparator peripheral with a software sigma-delta routine, or migrate to PIC16F916-I/SS (8-bit ADC) or PIC16F883-I/SS (10-bit ADC). Also note that the 28-SSOP variant omits PORTE - any code targeting the 40-pin PIC16F913 variants will not link without conditional compilation. Confirm ICD/ICSP header footprint early; the 5-pin RJ11-style header must be accessible after board assembly.
Estimated: At 20 MHz, 5.5V VDD, and all peripherals active, core supply current is around 4 mA, dissipating about 22 mW. With a typical 28-SSOP theta_JA of 100 C/W, junction temperature rise is approximately 2.2C above ambient, well within the -40C to +85C industrial range. At 3.3V, current drops to ~2 mA, halving dissipation. No heatsink is required for any operating condition.
Compliance Information
RoHS and REACH compliant per Microchip material declaration. Not AEC-Q100 qualified; for automotive applications choose PIC16F913-I/SSVAO or PIC16F1933 automotive-grade variant. Halogen-free per Microchip packaging spec.
