PIC16LF1783-E/SS Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, a RISC CPU core, on-chip non-volatile program memory, working RAM, EEPROM data storage, and a fixed set of mixed-signal peripherals. Within the broader power-management and embedded hierarchy, the PIC16LF1783 belongs to: microcontroller -> 8-bit MCU -> PIC16 enhanced mid-range family -> mixed-signal PIC16LF178x sub-family -> ultra-low-power (XLP) tier. This positioning lets it replace multiple analog ICs (op-amps, DACs, comparators, references) while still consuming nanoWatt sleep currents.
Key features include 7 KB (4K x 14) self-programmable Flash, 512 B SRAM, 256 B EEPROM, a 12-bit ADC with up to 14 channels, an 8-bit DAC, three op-amps, two comparators, two PSMC peripherals with dead-band control and auto-shutdown, three CCP modules, EUSART, two I2C/SPI ports, an 11-bit timer and three 8-bit timers. The 32 MHz internal oscillator and 32 kHz low-frequency oscillator remove the need for an external crystal in most designs.
Typical applications include industrial sensor conditioning loops, automotive body and HVAC actuators, LED lighting drivers with PSMC, battery-powered IoT nodes, BLDC / brushed motor commutation via PSMC, and low-cost instrumentation front-ends. The on-chip op-amps drive signal conditioning ahead of the ADC and 8-bit DAC, while the PSMC peripherals deliver dead-band-protected complementary PWM for motor and power-converter topologies. Operating from -40 C to +125 C, the -E (extended) grade targets industrial and automotive underhood designs.

Typical Applications
PIC16LF1783-E/SS is suitable for 7 applications: Industrial Sensor Conditioning, Automotive Body & HVAC Actuators, LED Lighting Drivers with PSMC, Battery-Powered IoT Edge Nodes, BLDC and Brushed Motor Commutation, Low-Cost Instrumentation Front-Ends, Consumer Appliance Control.
Industrial Sensor Conditioning
The PIC16LF1783-E/SS is well matched to industrial sensor-conditioning loops where a single MCU must digitize low-level analog signals and drive outputs back into the plant. Its 12-bit ADC with up to 14 channels handles strain-gauge, thermocouple and 4-20 mA front-ends, while the three on-chip op-amps deliver the gain and reference buffering that normally require a separate quad-op-amp IC. The 8-bit DAC provides a programmable excitation or setpoint, and the 1.8-3.6 V nanoWatt XLP supply keeps heat low in dense DIN-rail modules. Combined with EUSART and I2C for sensor-bus connectivity, this PIC can replace a discrete MCU plus analog chain.
Recommended
Automotive Body & HVAC Actuators
The PIC16LF1783-E/SS operates from -40 C to +125 C and integrates PSMC peripherals, making it a strong fit for automotive body and HVAC actuators such as blend doors, blowers and headlamp levellers. The PSMC modules generate complementary PWM with programmable dead-band and auto-shutdown, removing the need for a dedicated motor-driver analog front-end. The 12-bit ADC reads feedback pots and current-sense shunts, while the op-amps amplify low-level signals directly at the MCU pins. Operating from a 3.3 V post-regulator, the device draws nanoWatt sleep currents when the bus is idle, satisfying automotive quiescent-current budgets.
Recommended
LED Lighting Drivers with PSMC
LED drivers and architectural lighting fixtures benefit from the PIC16LF1783-E/SS's PSMC peripherals and 8-bit DAC combination. The PSMC generates high-resolution PWM for constant-current LED strings, including dimming curves via the DAC, while the 12-bit ADC closes the loop on a photodiode or shunt for lumen maintenance. The 1.8-3.6 V supply enables direct Li-ion or 3.3 V bus operation without an LDO, and the 32 MHz CPU supports DALI, 0-10 V or DMX control protocol stacks. Active current remains low enough to skip a switching regulator in favor of a linear dropper in many low-power fixtures.
Recommended
Battery-Powered IoT Edge Nodes
The PIC16LF1783-E/SS's nanoWatt XLP architecture targets battery-powered IoT edge nodes such as wireless environmental sensors, smart locks and wearables. Active current at 32 MHz stays in the milliamp range, while deep-sleep currents drop to sub-microamp levels, enabling multi-year battery life from a coin cell. The 12-bit ADC captures temperature, humidity and gas-sensor outputs, and the 8-bit DAC generates reference voltages for downstream analog blocks. EUSART plus I2C/SPI ports connect to radios such as the MCP2120 or RN4870, with the LF supply range (1.8-3.6 V) matching a single Li-ion or 2x AA profile.
Recommended
BLDC and Brushed Motor Commutation
Small BLDC fans, brushed DC pumps and stepper motors can be driven by the PIC16LF1783-E/SS using its PSMC peripherals and 12-bit ADC. The PSMC provides dead-band-protected complementary outputs with auto-shutdown, while the ADC samples back-EMF or current-sense amplifiers built from the on-chip op-amps. The 32 MHz instruction rate supports sensorless back-EMF zero-crossing detection at low RPM, and the 256-byte EEPROM stores per-motor calibration tables. The -E temperature grade covers underhood automotive and industrial pump environments.
Recommended
Low-Cost Instrumentation Front-Ends
Test, measurement and laboratory instrumentation often needs a small MCU to digitize sensors, drive displays and run calibration. The PIC16LF1783-E/SS combines a 12-bit ADC, 8-bit DAC and three op-amps in one 28-SSOP package, replacing a discrete signal chain. The 7 KB Flash accommodates modest UI logic, and the EUSART port streams data to a host PC or USB-UART bridge. The 1.8-3.6 V supply range simplifies battery-powered handhelds, while the -40 C to +125 C rating allows the same firmware to serve indoor lab and outdoor field deployments.
Recommended
Consumer Appliance Control
White goods and small consumer appliances such as coffee makers, blenders and air purifiers benefit from the PIC16LF1783-E/SS's mixed-signal integration. The MCU reads user inputs via ADC, drives triacs or PSMC PWM outputs to control heating elements and motors, and updates an LED or LCD display. The three op-amps condition sensor inputs without external analog ICs, and the 256-byte EEPROM stores user presets and calibration values across power cycles. Operating from a 3.3 V rail derived from the mains, the device's nanoWatt XLP sleep mode keeps standby power within energy-star limits.

- Extended -40C to +125C temperature grade (vs PIC16LF1783-I/SS)
Design Notes
Estimated: the PIC16LF1783-E/SS consumes approximately 4 mA active at 32 MHz / 3.3 V and drops below 1 uA in sleep with RTC running. For battery designs, use the nanoWatt XLP sleep modes (SLEEP + WDT) and wake via IOC or RTC. Always place a 100 nF decoupling capacitor within 5 mm of VDD (pin 20) and a 10 uF bulk capacitor on the supply rail to handle ADC reference inrush.
Route the analog signals (ANx, DACOUT) away from the PSMC PWM outputs and the secondary oscillator pins to avoid coupling into the 12-bit ADC. Use a ground plane under the 28-SSOP and stitch vias around its perimeter. Keep the MCLR trace short and add the typical 10 kohm pull-up; do not leave MCLR floating or the device may enter programming mode spuriously. Avoid running high-current switching traces under the IC to minimize digital noise injection into the analog domain.
Do not assume pin 1 (MCLR/VPP) can be left floating - it requires a pull-up to VDD via 10 kohm for normal operation. The 12-bit ADC's reference voltage must be stable; if using VDD as reference, add a ferrite bead or pi-filter on VDD to suppress PSMC-induced ripple. When migrating from PIC16F1783 (F-version, 1.8-5.5 V) to PIC16LF1783 (LF, 1.8-3.6 V), verify that downstream 5 V peripherals still operate correctly. Finally, the LF1783 supports a maximum of 32 MHz - do not enable the PLL with an 8 MHz crystal expecting 64 MHz.
Compliance Information
RoHS and REACH compliant per Microchip product environmental compliance information. /E temperature grade supports automotive-grade operating temperatures (-40C to +125C) but is not formally AEC-Q100 qualified; consult Microchip automotive product line for AEC-Q100 variants.
