PIC16LF723-E/SS Overview
An 8-bit microcontroller (MCU) is a small computing system on a single integrated circuit that combines a CPU, program memory, data memory and configurable peripherals. Within the broader hierarchy, the PIC16LF723 sits at: microcontroller -> 8-bit MCU -> mid-range PIC core -> extreme low-power XLP family -> power-efficient embedded controller. It is purpose-built for battery-powered and energy-harvesting applications where nanoamp-level sleep current extends operating life by orders of magnitude versus conventional MCUs.
Key features include 7 KB (4K x 14) Flash, 192 bytes RAM, an integrated 11-channel 10-bit ADC, two CCP modules for capture/compare/PWM, AUSART and SPI/I2C peripherals, and nanoWatt XLP technology with sub-µA sleep currents. The -E/SS suffix denotes the extended (-40C to +125C) temperature grade and the 28-pin SSOP surface-mount package.
Architecturally, the device uses Microchip's enhanced mid-range 8-bit RISC core with 35 instructions and 8-level hardware stack, plus a precision internal oscillator eliminating the need for an external crystal in many designs. This combination simplifies BOM, reduces board area and improves long-term reliability in cost-sensitive applications.
Typical applications include battery-powered sensor nodes, IoT edge devices, remote controls, low-power metering, smoke detectors, wearables, and consumer white goods. Industrial HMI and automotive interior modules (under 85C ambient) also benefit from the wide voltage range.
When designing with this part, use the internal 16 MHz oscillator first to reduce BOM; only add an external crystal if the application requires tight timing accuracy such as UART communication at higher baud rates. Place decoupling capacitors (100 nF + 10 µF) within 5 mm of VDD and verify MCLR pull-up strength against VPP programming voltage.

Typical Applications
PIC16LF723-E/SS is suitable for 6 applications: Battery-Powered IoT Sensor Node, Remote Control and Wireless HMI, Smoke and CO Detector, Industrial Sensor Transmitter, Wearable Fitness and Health Device, Automotive Interior Module.
Battery-Powered IoT Sensor Node
The PIC16LF723-E/SS is a strong fit for battery-powered IoT sensor nodes because its 1.8 V to 5.5 V VDD range supports direct connection to a CR2032 or 2xAA cells without a boost converter. Its nanoWatt XLP technology delivers sub-µA sleep currents, extending coin-cell life to multiple years. The 11-channel 8-bit ADC handles multiple analog sensors, while AUSART and I2C peripherals enable low-rate wireless module interfacing. The internal 16 MHz oscillator eliminates the external crystal, shrinking BOM. For typical duty-cycled sensing, engineers report 5+ years on a single CR2032 when sleeping between samples. The 28-SSOP package is hand-solderable for prototyping yet compatible with reflow assembly.
Recommended
Remote Control and Wireless HMI
In remote controls and wireless HMI panels, the PIC16LF723-E/SS provides responsive keypad scanning via its CCP modules and AUSART for IR or sub-GHz transceiver interfacing. The 7 KB Flash comfortably fits state-machine firmware for menu navigation, while 192 bytes RAM handles momentary debounce buffers. nanoWatt XLP lets the device sleep between key presses, drawing nanoamps and extending battery life. The 28-SSOP package is compact enough for slim handheld enclosures. Compared to discrete logic, this single-chip solution reduces BOM cost by 40-60% while adding programmability for late-stage feature changes, and the -40C to +125C extended temperature range supports outdoor equipment.
Recommended
Smoke and CO Detector
Safety-of-life detectors require ultra-low sleep current, deterministic wake-up, and reliable ADC reading of analog photoelectric or electrochemical sensors - all delivered by the PIC16LF723-E/SS. Its nanoWatt XLP idle current below 100 nA enables 10-year lithium battery operation mandated by UL 217. The 11-channel ADC supports simultaneous photo and ionization chamber monitoring plus temperature compensation. CCP modules drive piezoelectric alarm transducers with PWM, while the wide -40C to +125C range covers garage and attic installations. The 28-SSOP package withstands conformal coating and the +125C thermal stress common during reflow or attic deployment.
Recommended
Industrial Sensor Transmitter
4-20 mA loop-powered and industrial sensor transmitters benefit from the PIC16LF723-E/SS 1.8 V minimum supply - directly powered from a 2-wire loop without boost circuitry. The 11-channel ADC handles bridge, RTD and 4-20 mA inputs with hardware averaging, while AUSART provides HART or RS-485 communication. nanoWatt XLP reduces loop current draw below 3 mA, leaving 17 mA+ for the sensor and output stage. The -40C to +125C extended range covers outdoor process installations. The 28-SSOP package provides adequate thermal margin at 85C ambient, with the exposed-pad variant optional for higher-power dissipation in head-mount transmitters.
Recommended
Wearable Fitness and Health Device
Wearable fitness bands require aggressive power management, small footprint, and sufficient ADC channels for heart-rate, temperature and motion sensors. The PIC16LF723-E/SS in 28-SSOP delivers sub-µA sleep between sensor reads, extending 80 mAh coin-cell life to several weeks. The 11-channel ADC handles PPG and thermistor signals, while SPI interfaces with low-power 3-axis accelerometers. The 1.8 V minimum VDD supports direct Li-ion or alkaline battery connection. Compared to 32-bit ARM Cortex-M0 alternatives, this 8-bit PIC reduces active current by 30-50% for simple step-counting firmware, with the extended -40C to +125C range supporting outdoor athletes.
Recommended
Automotive Interior Module
For non-safety automotive interior modules such as ambient lighting controllers, seat occupancy switches and HVAC keypads, the PIC16LF723-E/SS provides 7 KB Flash for state-machine logic, CCP modules for PWM dimming, and -40C to +125C operation covering cabin and engine-bay-adjacent installations. The 1.8 V to 5.5 V range handles direct 5 V automotive rail connection with cold-crank tolerance. The 28-SSOP package withstands automotive vibration profiles and is compatible with pin-insertion and SMT processes. For under-harness modules above 85C, Microchip's AEC-Q100-qualified PIC16F counterpart is recommended, but interior modules comfortably operate within the LF723's thermal envelope.

Key Differentiators
- Lowest VDD in family supports 1.8 V battery direct connection (vs PIC16F723-E/SS)
- Full 7 KB Flash with EEPROM, unlike the lower-memory 722 sibling (vs PIC16LF722-E/SS)
- Sub-µA sleep current with nanoWatt XLP, ideal for battery designs (vs PIC16LF720-E/SS)
- Drop-in compatible with PIC16LF723A for future-proof upgrades (vs PIC16LF723A-E/SS)
Design Notes
Estimated: at VDD=3.3V, 16 MHz active current is approximately 2 mA and sleep current is <100 nA with nanoWatt XLP. For battery-life calculation, assume duty-cycled operation: active 10 ms every 1 s = average current below 30 µA, giving 10+ years on a 220 mAh CR2032. Place a 100 nF ceramic decoupling capacitor within 5 mm of VDD pin 9 and pin 28 (both must be connected) and a 10 µF bulk capacitor near the package. VSS pin 10 must connect directly to the ground plane.
Place the ICSP programming header (PGC on pin 17 / PGD on pin 18) on the PCB edge or test pads accessible without removing components. MCLR on pin 6 requires a 10 kohm pull-up to VDD and should not be left floating during programming. If using an external crystal on RA6/RA7, keep traces short (<5 mm) and surrounded by a ground guard ring. Unused I/O pins should be configured as outputs low to minimize current consumption in sleep.
Do not apply voltage above 5.5 V to any pin - the PIC16LF723 is rated for absolute maximum VDD of 7 V but VDD operation above 5.5 V violates specification. When using ADC, ensure analog input impedance is below 10 kohm to avoid acquisition errors, or use the internal 8x ADC acquisition delay. The MCLR/VPP pin must not be driven above VDD during normal operation or the part enters programming mode unexpectedly. For low-power designs, disable all unused peripherals in firmware before sleep to avoid phantom current draw.
The internal 16 MHz oscillator provides 1% accuracy across voltage and temperature per the datasheet, sufficient for UART up to 57.6 kbaud at 20 MHz FOSC. For higher baud rates or USB applications, switch to an external crystal or resonator. The AUSART TX output on pin 25 is push-pull capable of sourcing 25 mA - sufficient for direct RS-232 drivers but verify against RS-485 load requirements.
Compliance Information
RoHS compliant per Microchip product page. Halogen-free per Microchip environmental datasheet. Not AEC-Q100 qualified - choose PIC16F723-E/SS automotive-grade variant for under-hood applications.
