PIC16LF1783-E/SO 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. Within the PIC ecosystem, the 8-bit PIC16 family occupies the mid-range segment, balancing code efficiency, peripheral richness, and low cost. The 'LF' prefix designates the F-version (Flash) silicon implemented on a low-power process node, allowing operation down to 1.8 V supply while still supporting analog peripherals. The PIC16LF1783 series is positioned above the PIC16F170x series in memory and peripheral count.
Key features of the PIC16LF1783 include 7 KB self-programmable Flash, 256 bytes of EEPROM data memory, 512 bytes of RAM, 28 I/O pins, an enhanced 16-bit capture/compare/PWM module, multiple communications peripherals (I²C, SPI, UART with LIN support), and an internal 32 MHz precision oscillator that eliminates the need for an external crystal in many designs. The 'E' suffix indicates the extended industrial temperature grade (-40°C to +125°C), and the /SO suffix denotes the 28-pin SOIC package with 300-mil body width suitable for hand-soldering or standard SMT lines.
Architecturally, the PIC16LF1783 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word and an 8-level hardware stack. The on-chip CIP peripherals (CLC, NCO, COG, DSM, ZCD) allow signal conditioning and waveform generation without CPU intervention, reducing power consumption and latency. The internal voltage reference and zero-cross detect (ZCD) are particularly useful in lighting and motor-control sub-systems.
Typical applications for the PIC16LF1783-E/SO include battery-powered IoT sensor nodes, white-goods and appliance user interfaces, low-power wireless sensor transmitters, LED lighting controllers with dimming, HVAC thermostatic controls, automotive body electronics (non-safety), and portable medical accessories where low quiescent current and small footprint matter. The 28-SOIC package simplifies prototyping on through-hole adapter boards while still being production-suitable.
When designing with this MCU, verify the supply voltage range against your analog-peripheral requirements (e.g., the 12-bit ADC has a specific Vdd_min). Place a 100 nF decoupling capacitor as close as possible to the VDD pin and add a bulk capacitor (>=1 µF) on the main supply rail. Use the internal 32 MHz oscillator for BOM cost savings only if the ±2% frequency tolerance is acceptable for your UART baud-rate budget; otherwise, specify a crystal. Configuration bits must be set in code to select the correct oscillator source and disable unused peripherals for lowest sleep current.
This page synthesizes verified distributor pricing, same-brand drop-in alternatives in the same 28-SOIC footprint, and practical design notes drawn from Microchip's published PIC16F1783 family datasheet and PIC16F1783 device summary to help engineers select and source this MCU.

主な用途
PIC16LF1783-E/SO の用途: 7 件s: Battery-Powered IoT Sensor Nodes, White-Goods and Appliance User Interfaces, LED Lighting Controllers with Dimming, HVAC Thermostatic Controls, Portable Medical Accessories, Automotive Body Electronics, Remote Controls and Wireless Key Fobs.
Battery-Powered IoT Sensor Nodes
The PIC16LF1783-E/SO's eXtreme Low Power (XLP) architecture, with sub-µA sleep currents and an internal 32 MHz HFINTOSC, makes it ideal for battery-powered IoT sensor nodes that wake periodically to transmit over Sub-GHz radios or BLE companion chips. The 1.8 V to 3.6 V supply matches two alkaline or one Li-ion cell directly. The 12-bit ADC, 8-bit DAC, and CIP peripherals (CLC, NCO, COG) handle sensor signal conditioning autonomously, so the CPU can stay asleep and only wake on interrupt. Pin-to-pin compatibility with the PIC16F1783 lets designers swap to 5 V variants for non-battery edge nodes without board changes.
おすすめ
White-Goods and Appliance User Interfaces
Front-panel controls on washing machines, dishwashers, refrigerators, and microwave ovens benefit from the PIC16LF1783-E/SO's 28 I/O pins, multiple PWM channels, and integrated 12-bit ADC for reading keypads, rotary encoders, and NTC temperature sensors. The on-chip ZCD (zero-cross detect) and COG (complementary output generator) enable direct triac control of AC loads without extra glue logic. The extended industrial -40 °C to +125 °C temperature range handles the thermal environment inside appliance cabinets. The wide-body 28-SOIC is easy to hand-solder during prototyping and supports standard SMT production lines.
おすすめ
LED Lighting Controllers with Dimming
LED drivers with analog dimming or 0-10 V control loops can use the PIC16LF1783-E/SO to provide the constant-current feedback loop, color mixing, and DMX-style command interpretation. The 16-bit PWM with independent time bases drives high-resolution dimming, while the 12-bit ADC senses LED current and thermistor feedback. The CLC peripherals combine PWM and comparator outputs to implement active PFC or valley-fill switching. Operating from 1.8 V to 3.6 V matches constant-current driver ICs that operate from the LED string forward voltage.
おすすめ
HVAC Thermostatic Controls
HVAC wall thermostats combine temperature and humidity sensing, latching relay control, and user-interface management, all of which the PIC16LF1783-E/SO addresses with its 12-bit ADC, on-chip comparators, and 28 I/O. Sleep currents below 1 µA extend battery life in wireless thermostats, while the -40 °C to +125 °C range supports installation in unconditioned spaces. The 7 KB Flash accommodates HVAC state machines with predictive control algorithms. Pin-compatibility with the PIC16F1783-E/SO supports a 5 V variant when line-powered rather than battery-powered.
おすすめ
Portable Medical Accessories
Portable medical accessories such as blood-pressure cuffs, pulse oximeters, and connected pill dispensers benefit from the PIC16LF1783-E/SO's XLP sleep behavior and on-chip 12-bit ADC for analog front-end digitization. The CIP peripherals offload signal conditioning from the CPU, lowering latency and total energy per measurement. The wide 1.8 V to 3.6 V supply accommodates 2xAA or single Li-ion batteries. Designers should ensure the chosen firmware follows IEC 62304 software lifecycle practices; this MCU is intended for accessory hardware, not for direct patient-contact diagnostic devices.
おすすめ
Automotive Body Electronics
Non-safety automotive body applications such as seat heaters, mirror adjusters, interior lighting, and accessory controllers are well-served by the PIC16LF1783-E/SO's extended -40 °C to +125 °C temperature range and 32 MHz processing headroom. The PIC16F1783 variants are AEC-Q100 qualified for automotive use, and the PIC16LF1783 shares the same die. The CIP peripherals drive MOSFET bridges and read back current sense amplifiers without CPU intervention. Designers of safety-critical body systems (airbag, ABS, EPS) should still migrate to a dedicated AEC-Q100 functional-safety MCU.
おすすめ
Remote Controls and Wireless Key Fobs
Low-cost RF remote controls, garage-door key fobs, and consumer wireless switches benefit from the PIC16LF1783-E/SO's nanoamp sleep current and ability to wake on interrupt from a button press. The 28-SOIC package is easy to hand-assemble during prototyping, and the 32 MHz HFINTOSC drives OOK/FSK transmitters without external RF clocks. The 7 KB Flash supports rolling-code encryption algorithms. Drop-in alternatives in the same 28-SOIC package (PIC16LF1783-I/SO, PIC16F1783-I/SO) let designers switch supply voltage without PCB changes.

設計ノート
Decouple VDD (pin 19) with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a 1 µF to 10 µF bulk capacitor on the same supply rail. The PIC16LF1783-E/SO can wake from sleep in <5 µs when the HFINTOSC is selected, but add bulk capacitance if your load transients during wake-up risk rail collapse. Use the LF silicon variant only between 1.8 V and 3.6 V; for 5 V rails, switch to the PIC16F1783-E/SO without changing the PCB footprint.
Do not leave the MCLR pin (pin 28 / RE3) floating - either tie it to VDD through a 10 kΩ pull-up or use the internal MCLR function via configuration bits. Floating MCLR causes intermittent resets and unreliable startup. Similarly, ensure unused I/O pins are configured as outputs low (not left as inputs) to minimize sleep current; an input left floating can draw tens of microamps. Refer to the PIC16F1783 family datasheet 'Power-Saving Tips' section for additional peripheral gating patterns.
The PIC16LF1783-E/SO is rated for junction temperatures up to +150 °C and ambient up to +125 °C in the extended industrial E grade. In enclosed housings (e.g., sealed appliance controls), verify that worst-case self-heating plus ambient does not exceed the temperature grade. Estimated: at full 32 MHz CPU activity the die dissipates well under 50 mW, so thermal concerns are dominated by ambient rather than self-heating for typical designs.
Route ICSP signals (PGC = pin 26, PGD = pin 27) as short, parallel traces and place a 4.7 kΩ pull-up on MCLR for production programming access. If your layout reserves a 6-pin header footprint for PICkit 5 in-circuit debugging, add a labeled test point group near the MCU. For noise-sensitive analog measurements, route the ADC inputs (RA0-RA7) over a contiguous ground plane and avoid crossing them with PWM or switching traces to minimize digital coupling.
If you use the internal 32 MHz HFINTOSC for UART communications, the factory calibration is typically ±1% across 0 °C to +60 °C but can drift to ±2% across the full -40 °C to +125 °C extended range. For tight baud-rate budgets (e.g., 115200 bps at high temperature), enable the Auto-Baud Detect feature or specify an external crystal. Verify the actual error tolerance against your UART partner using the worst-case oscillator frequency at your maximum operating temperature.
