PIC16LF1773-E/SP Overview
A microcontroller (MCU) in this class is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a programmable peripheral set into one package. The PIC16F architecture sits at the low-power, deterministic end of the 8-bit MCU spectrum, in the broader hierarchy of microcontroller -> embedded controller -> semiconductor IC. Designers choose this category when cost, simplicity, deterministic interrupt latency, and ultra-low sleep current matter more than raw processing throughput.
The on-chip 10-bit DAC, multiple PWM channels, op-amps, comparators, and zero-cross detection make the PIC16LF1773 stand out for lighting, switch-mode power supply, battery-charging, and motor-control subsystems. The XLP variant adds nanoWatt sleep modes that drop quiescent current below 1 uA, enabling years of operation from a single coin cell. Internal oscillator trimming and the configurable instruction set let firmware trade speed for current on the fly.
Typical applications include LED drivers with dimming and color mixing, digital power supplies with closed-loop control, e-bike / e-scooter battery management, BLDC motor commutation, and general-purpose sensor hubs. The wide peripheral mix reduces external component count and PCB area versus discrete analog implementations.
When designing with this device, verify that the SPDIP-28 footprint matches the PCB drill pattern; the through-hole lead pitch is 2.54 mm and is not pin-compatible with the SOIC, SSOP, QFN, or UQFN variants of the same die. Use MPLAB X IDE with the XC8 compiler for code development and the PICkit 4 or MPLAB Snap programmer for in-circuit debug.

Typical Applications
PIC16LF1773-E/SP is suitable for 7 applications: Tunable-White LED Driver with DAC-Based Analog Dimming, Switch-Mode Power Supply (SMPS) Primary-Side Controller, E-Bike Battery Charger Controller, BLDC Motor Commutation Controller, General-Purpose Industrial Sensor Hub, Consumer Appliance User-Interface Controller, Automotive Interior LED Lighting Module (Non-Safety).
Tunable-White LED Driver with DAC-Based Analog Dimming
The PIC16LF1773-E/SP fits tunable-white LED drivers because its integrated 10-bit DAC drives the analog dimming reference for a constant-current regulator without an external DAC IC. Placed as the master controller with its XLP core running at 4 MHz HFINTOSC, the LF core draws only 1.8V-3.6V, matching 2xAA or single-cell Li-ion battery rails in table lamps and accent lighting. The seven 10-bit PWM channels are routed to one warm-white and one cool-white string, while the 10-bit DAC sets the analog fold-back for thermal compensation. Compared with a switching supply the LF core adds no EMI to the LED current loop, and the 512-byte RAM is sufficient for I2C temperature-sensor polling and logarithmic dimming lookup tables.
Recommended
Switch-Mode Power Supply (SMPS) Primary-Side Controller
The PIC16LF1773-E/SP is well-matched to primary-side regulated flyback and buck converters because it combines the 10-bit DAC for compensation-loop reference, comparators for peak-current sensing, and zero-cross detection for QR-mode valley switching in a single 28-SPDIP. The 32 MHz instruction rate delivers the 8 MIPS needed for a 100 kHz closed-loop cycle with cycle-by-cycle current-mode control, while the 7 KB Flash stores the firmware plus a tuning menu. Designers can lower BOM cost by replacing the TL431 + opto-coupler feedback with the on-chip DAC and comparator pair. The LF core is suitable for 3.3V-derived bias supplies in sub-65W adapters and USB-PD secondary-side controllers.
Recommended
E-Bike Battery Charger Controller
For e-bike and e-scooter battery chargers, the PIC16LF1773-E/SP provides a CC/CV charge profile without an analog front-end IC: the 10-bit DAC programs the constant-current reference while the on-chip op-amp senses pack current across a low-side shunt. The 7 KB Flash is sufficient for Li-ion multi-stage charging with temperature fold-back, and the XLP nanoWatt sleep mode drops standby current below 1 uA when the bike is parked, satisfying IEC 62133 storage-current limits. The extended -40C to +125C temperature grade tolerates under-seat thermal conditions, and the 28-SPDIP package allows hand-soldered prototype builds for small shops.
Recommended
BLDC Motor Commutation Controller
Sensorless or Hall-sensor BLDC commutation is a natural fit for the PIC16LF1773-E/SP, where the integrated comparators sense back-EMF zero-cross events and the 10-bit DAC generates the speed-reference voltage for closed-loop torque control. Six of the available PWM channels drive a 3-phase FET predriver such as the MCP8026, while 512 B of RAM holds the commutation state machine and slip-compensation filter. The LF core's 32 MHz / 8 MIPS throughput handles 20 kHz PWM and 60 electrical-RPM update rates; the 28-SPDIP package keeps fan and pump designs serviceable with through-hole assembly.
Recommended
General-Purpose Industrial Sensor Hub
As a sensor hub for industrial IoT edge nodes, the PIC16LF1773-E/SP combines multiple analog front-end blocks (op-amps, comparators, 10-bit DAC for sensor excitation) that would otherwise require separate analog ICs. I2C and SPI master peripherals drive external temperature, pressure, and humidity sensors, and the XLP sleep modes extend operating life on a coin cell to multi-year battery life for remote monitor applications. The 28-SPDIP package suits maintenance-friendly industrial enclosures, and the extended -40C to +125C range tolerates unheated cabinet deployment.
Recommended
Consumer Appliance User-Interface Controller
In consumer appliances such as coffee makers, induction cooktops, or air purifiers, the PIC16LF1773-E/SP drives segmented LED or character displays, scans capacitive touch keys, and regulates the appliance's sub-system. The 10-bit DAC drives the audio click track for button-press feedback without a separate DAC IC, and the XLP sleep modes reduce standby power to satisfy EU EcoDesign regulations. With 7 KB Flash and 512 B RAM the MCU hosts both UI firmware and the safety-monitoring state machine, and the 28-SPDIP package simplifies through-hole manufacturing for low-cost appliance production lines.
Recommended
Automotive Interior LED Lighting Module (Non-Safety)
For non-safety automotive interior lighting - dome lights, footwell ambient strips, and RGB mood lighting - the PIC16LF1773-E/SP supplies the multi-channel PWM and 10-bit DAC color-mixing capability in a 28-SPDIP package. The -40C to +125C extended grade covers cabin temperature conditions; AEC-Q100 qualification is NOT claimed on the PIC16LF1773-E/SP, so use the PIC16F1773-E/SP automotive equivalent for safety-relevant applications. LIN or CAN connectivity is added via an external MCP2515 / TJA1027 transceiver, and the 32 MHz / 8 MIPS throughput supports 100 Hz color-mixing refresh without flicker.

Key Differentiators
- Integrated 10-bit DAC eliminates an external DAC IC in lighting and SMPS designs (vs PIC16F1769-E/SP)
- LF low-voltage core enables 1.8V-3.6V battery operation, no separate regulator required (vs PIC16F1773-E/SP (5V F core))
- Extended -40C to +125C temperature grade for industrial and under-hood deployment (vs PIC16LF1773-I/SP (industrial -40C to +85C))
- 28-SPDIP through-hole package simplifies prototyping and field-replaceable assemblies (vs PIC16LF1773-E/ML (28-QFN))
Design Notes
Estimated: at VDD = 3.3 V and a 32 MHz CPU clock driving the LF core at full throughput, the PIC16LF1773-E/SP draws approximately 7 mA active. In XLP sleep mode the same part drops below 1 uA. Decouple VDD / VDDIO with a 100 nF ceramic capacitor placed within 3 mm of the supply pin and a bulk 1-10 uF tantalum or aluminum-polymer capacitor on the rail. PIC16F1 parts are particularly sensitive to VDDIO noise on high-impedance analog inputs - keep digital I/O traces away from the AN0-AN19 traces and add a guard ring for best ADC / DAC noise performance.
The 28-SPDIP through-hole footprint is 0.300 inch / 7.62 mm wide with 0.100 inch / 2.54 mm lead pitch. Drill 0.9 mm plated through-holes (0.038 inch), with annular rings >= 0.2 mm to satisfy IPC-2222 Class 2. Leave 0.5 mm clearance between the lead pad and any signal trace routed between pins. Adding a ground pour under the chip body is optional - the SPDIP package does not require a thermal pad and the die dissipates less than 100 mW in typical applications, so no copper heatsink is required.
Do not confuse the /SP (28-SPDIP) suffix with /SO (28-SOIC), /SS (28-SSOP), /ML (28-QFN), or /MV (28-UQFN) - those packages share the same die but have completely different footprints and pinouts. Also confirm whether your design needs the LF (1.8V-3.6V) or F (2.3V-5.5V) core; the LF core cannot run from a 5V supply. Programming via ICSP requires PGECX / PGEDX to be free of any strong pull-ups - in-circuit debug will fail if those lines are pulled to logic high through less than ~10 kohm.
Estimated: the PIC16LF1773-E/SP dissipates a maximum of approximately 0.3 W at full active load with all peripherals enabled (calculated from VDD=3.6V and IDD active ~85 mA worst case). At 28-SPDIP thermal resistance theta_JA ~= 60 C/W, junction temperature rise above ambient is ~18C at 0.3 W. This is well within the -40C to +125C extended grade. Designers in sealed enclosures should still measure the actual die temperature via the on-chip Temperature Indicator Diode, which provides +/- 3C accuracy after single-point calibration.
When using the on-chip 10-bit DAC for sensor excitation or LED analog dimming, add a 10 nF - 100 nF capacitor on the DAC output pin to filter the step response; the DAC output bandwidth extends to roughly 50 kHz. For SPI bus speeds above 4 MHz on SCK2 / SDO2 (pins 26-27), use 22 ohm source-series termination to dampen ringing on long PCB traces, and avoid routing SCK alongside RB0-7 which carry high-current PWM outputs. XLP sleep modes preserve the state of digital peripherals but freeze the ADC and DAC; wake only on a configured interrupt to keep power consumption low.
