PIC16LF1718-E/MV 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash), data memory (RAM), and programmable peripherals. The PIC16F1718 family sits within the 8-bit PIC® microcontroller hierarchy, descended from the PIC16 mid-range architecture. It targets general-purpose embedded designs where intelligent analog integration, peripheral flexibility, and ultra-low standby current are required.
Key features include integrated op-amps, a 10-bit ADC with 17 channels, a 5-bit and 8-bit DAC, two comparators with selectable hysteresis, Zero Cross Detect (ZCD), Configurable Logic Cells (CLC), Complementary Output Generator (COG), Numerically Controlled Oscillator (NCO), and Peripheral Pin Select (PPS) for flexible I/O mapping. Communications are handled by EUSART, I2C, and SPI peripherals. The -E suffix denotes the -40C to +125C extended operating temperature range for industrial applications.
Architecturally, the PIC16LF1718 employs a Harvard RISC core with a 14-bit instruction word and hardware stack, executing most instructions in one oscillator cycle. The 'LF' (low-voltage / low-power F) variant uses flash memory that operates down to 1.8V, while Intelligent Analog peripherals continue to function across the entire supply range. Core Independent Peripherals (CIPs) such as CLC and NCO offload timing-critical tasks from the CPU, reducing firmware complexity.
Typical applications include IoT sensor nodes, battery-powered remote controls, energy harvesting systems, LED lighting controllers, small appliances, and industrial sensor interfaces. The combination of op-amps and 10-bit ADC on-chip removes the need for external analog front-ends in many designs.
When designing with this part, allocate at least one PCB layer or a generous copper pour to the exposed thermal pad (EP) for proper heat dissipation and ground continuity. PPS allows remapping of digital peripherals after PCB layout, simplifying pin assignments late in the design cycle.

主な用途
PIC16LF1718-E/MV の用途: 7 件s: Battery-Powered IoT Sensor Node, LED Lighting and Dimming Controllers, Industrial Sensor Signal Conditioning, Small Appliance and White-Good Controls, Energy-Harvesting Wireless Switch, Automotive Body Electronics (Sub-System), Consumer Remote Control and HMI.
Battery-Powered IoT Sensor Node
The PIC16LF1718-E/MV fits battery-powered IoT sensor nodes by combining 1.8V minimum supply operation with extreme-low-power XLP sleep currents under 1 uA. The integrated 10-bit ADC and on-chip op-amps condition thermocouple, thermistor, or strain-gauge signals without external analog ICs, while 2 KB RAM supports buffering of sensor samples before uplink. PPS allows late pin reassignment after PCB layout, easing RF antenna keep-out adjustments. With 28 KB Flash it can host a LoRaWAN or BLE stack fragment alongside application logic, enabling multi-year coin-cell life in remote monitoring deployments.
おすすめ
LED Lighting and Dimming Controllers
The PIC16LF1718-E/MV serves LED lighting controllers by using its Zero Cross Detect (ZCD) for TRIAC dimming synchronization and the 8-bit DAC for smooth logarithmic dim curves. The Configurable Logic Cell (CLC) and Complementary Output Generator (COG) drive half-bridge FETs directly, removing external timing ICs in PFC and constant-current topologies. 28 KB Flash is ample for color-mixing algorithms across RGBW channels. With 1.8V operation the MCU can be powered from auxiliary winding on a high-voltage buck, reducing BOM cost in commercial luminaires.
おすすめ
Industrial Sensor Signal Conditioning
The PIC16LF1718-E/MV fits industrial 4-20 mA loop transmitters and bridge-sensor conditioners. Two on-chip op-amps provide instrumentation-amp front-end for load cells or pressure sensors, while the 17-channel 10-bit ADC digitizes multiple process variables with hardware averaging. The -40C to +125C E temperature grade ensures operation in field-mounted enclosures. PPS lets engineers remap EUSART and I2C pins after PCB layout revisions, accelerating iteration when adding HART or IO-Link interfaces to existing modules.
おすすめ
Small Appliance and White-Good Controls
The PIC16LF1718-E/MV integrates well into coffee makers, washing machines, and microwave user-interface panels. The CLC implements capacitive-touch sensing and button de-bounce in hardware, while the on-chip comparators detect zero-cross on AC mains for TRIAC firing. With 2 KB RAM the MCU drives segmented LCD or LED displays with multiplexing. The 32 MHz CPU handles motor-control algorithms for BLDC or universal motors, reducing the need for a dedicated motor-control MCU in cost-sensitive consumer appliances.
おすすめ
Energy-Harvesting Wireless Switch
The PIC16LF1718-E/MV operates down to 1.8V, making it a fit for kinetic or solar energy-harvesting wireless light switches. Sleep currents below 1 uA ensure harvested energy suffices for years of operation without battery replacement. The on-chip op-amp can directly amplify a piezoelectric harvester signal, while the Numerically Controlled Oscillator (NCO) generates accurate Sub-GHz OOK/FSK modulation. With 28 KB Flash, the MCU handles proprietary or BLE Mesh protocol stacks without external memory.
おすすめ
Automotive Body Electronics (Sub-System)
The PIC16LF1718-E/MV supports body-electronics sub-systems such as ambient lighting controllers, mirror adjusters, and seat-occupancy detectors when used in non-safety automotive contexts. The E temperature grade covers the -40C to +125C automotive interior range, and PPS simplifies routing of LIN or CAN-friendly EUSART signals. Two op-amps interface directly with photodiodes or Hall-effect sensors, reducing external component count and PCB area in space-constrained door modules or instrument panels.
おすすめ
Consumer Remote Control and HMI
The PIC16LF1718-E/MV drives IR or RF remote controls and small HMI panels with its EUSART, PWM, and CLC peripherals. The on-chip 8-bit DAC generates audio click feedback without an external DAC, while CLC debounces tactile switches in hardware. The 1.8V minimum supply enables two-AAA battery operation for years of standby. PPS remapping supports late-stage PCB changes to optimize antenna placement without firmware rework.

設計ノート
The PIC16LF1718-E/MV LF variant operates from 1.8V to 3.6V. When migrating designs from the F variant (2.3V-5.5V), confirm that any upstream LDO or battery can supply at least 1.8V under full load. Decouple VDD with a 100 nF X7R ceramic placed within 3 mm of the VDD pin, plus a bulk 1 uF to 10 uF tantalum or ceramic cap to stabilize supply during ADC conversions.
The 28-UQFN (MV) package exposes a large central thermal pad (EP) that MUST be soldered to the PCB VSS plane for both thermal dissipation and electrical grounding. Use an array of thermal vias (typically 0.3 mm drill, 0.5 mm pitch, plugged or tented) under the EP to the inner VSS plane. Insufficient EP soldering can raise junction temperature 15C-25C above ambient at 32 MHz full activity.
Estimate: leave at least 2 mm clearance between the EP pad and any signal trace to allow proper solder wetting during reflow. The 28-UQFN 4x4 mm land pattern uses 0.4 mm pitch pads; ensure your PCB fabricator supports 0.1 mm trace/space. For noise-sensitive analog designs, dedicate one inner PCB layer as a continuous analog ground island beneath the MCU and its op-amp input traces.
Do not leave unused I/O pins floating - configure them as outputs or enable internal weak pull-ups. Floating inputs can draw mA-level shoot-through current and inject noise into the ADC readings. Also, when using the on-chip op-amps, ensure the output load (capacitance) does not exceed the 30 pF datasheet limit, or stability may be compromised. Always read the errata document before committing to production.
Route the analog op-amp input traces differentially and guard them with a ground trace tied to the analog ground island. Keep digital switching traces (PWM, EUSART, SPI) at least 3 mm from analog input traces, or use a perpendicular crossing if unavoidable. The ADC reference voltage (VREF+) should be bypassed with 100 nF + 10 uF caps within 5 mm of the pin to avoid ADC noise.
