PIC16LF1788-E/SO 概要
A PIC (Peripheral Interface Controller) microcontroller is an 8-bit RISC MCU built on Harvard architecture with separate program and data buses. PIC16F-series parts sit at the mid-range tier of Microchip's portfolio, integrating rich analog peripherals with low-power XLP technology for ultra-low standby current in always-on applications.
Key features include 12-bit and 5-bit digital-to-analog converters (DAC), advanced analog peripherals such as op-amps and comparators, multiple PWM modules, and communication interfaces including I2C, SPI, UART, and USART. The on-chip high-performance RISC CPU executes most instructions in a single cycle, contributing to deterministic interrupt response and efficient power profile.
The 32MHz internal oscillator enables accurate timing without external crystals. The architecture integrates enhanced mid-range core with 49 instructions and 16 stack levels, supporting self read/write capability on Flash. Integrated peripherals like the configurable logic cell (CLC) and signal measurement timer (SMT) simplify sensor and motor-control designs.
Typical applications include low-power IoT sensor nodes, industrial control interfaces, battery-operated instruments, LED lighting controllers, and small motor drives. The wide peripheral mix makes it well-suited to mixed-signal front-ends where analog precision and digital control must coexist on a single die.
Design consideration: When migrating between PIC16F1788 (F) and PIC16LF1788 (LF), note the LF variant supports lower voltage operation, while pin and peripheral assignments in identical package codes remain compatible for drop-in upgrades on existing boards.

主な用途
PIC16LF1788-E/SO の用途: 6 件s: Battery-Powered IoT Sensor Node, Industrial Control Interface Module, LED Lighting Controller, Portable Medical Monitoring Device, Small Motor Driver Control Board, Automotive Body Electronics Module.
Battery-Powered IoT Sensor Node
The PIC16LF1788-E/SO fits battery-powered IoT sensor nodes thanks to its 2.5V-3.3V LF supply range matching Li-ion/coin-cell discharge curves, plus XLP™ low-power technology enabling standby currents in the nanoamp range. Its 12-bit DAC and on-die op-amps can directly drive analog sensor front-ends for temperature, pressure, or gas sensors without external amplifiers. Used between a 3V Li-ion cell and the sensor chain, the LF variant extends usable runtime versus a standard F MCU at low battery voltages. The 32MHz speed and UART/SPI interfaces support periodic wireless transmissions to sub-GHz or BLE modules.
おすすめ
Industrial Control Interface Module
The PIC16LF1788-E/SO suits industrial control interface modules where its 49-instruction enhanced mid-range core delivers deterministic interrupt response for real-time control loops. The on-chip 12-bit DAC and operational amplifiers can synthesize 4-20mA analog output channels with minimal external analog. Its 2KB RAM and 28KB Flash comfortably host LIN, UART, and SPI stacks for master/slave industrial networks. Placed as the local MCU on a 24V industrial rail post-regulation, it adds LIN compatibility without needing an external transceiver controller.
おすすめ
LED Lighting Controller
The PIC16LF1788-E/SO drives multi-channel LED lighting controllers using its multiple PWM modules and 12-bit DAC for smooth dimming curves. The 256B EEPROM stores calibration values for individual LED channels, while 2KB RAM maintains color-mixing state for RGB or tunable-white systems. Operating from a 3.3V rail derived from an offline switching driver, it offers sequenced startup, soft-start, and thermal foldback via its on-die comparators. Its LIN/UART interfaces enable integration into automotive or architectural lighting networks.
おすすめ
Portable Medical Monitoring Device
The PIC16LF1788-E/SO is well-suited to portable medical monitoring devices because its 12-bit ADC and on-die op-amps can condition signals from biopotential electrodes, pulse oximeters, or temperature probes. The LF supply range allows direct connection to 3V coin cells, and the XLP™ low-power features stretch battery life during continuous monitoring. The 28KB Flash stores patient logs and calibration tables, while I2C/SPI can drive small OLED displays or BLE modules. Placed between a LiMnO2 primary cell and the analog front-end, it provides deterministic interrupt handling for safety-critical sampling.
おすすめ
Small Motor Driver Control Board
The PIC16LF1788-E/SO handles small brushless DC or stepper motor control via its multiple PWM modules, 12-bit DAC for current setpoints, and on-die comparators for back-EMF sensing. Its 32MHz instruction rate and deterministic interrupt response enable field-oriented control loops at moderate speeds. Operating from a 3.3V logic rail, the MCU issues gate-driver signals via SPI to external half-bridge drivers. The 28KB Flash accommodates sensorless startup routines, while 2KB RAM handles real-time state machines for commutation.
おすすめ
Automotive Body Electronics Module
The PIC16LF1788-E/SO supports automotive body electronics modules such as door controllers, seat adjusters, or lighting nodes where LIN bus connectivity, robust peripherals, and small package size matter. Its on-chip 12-bit ADC monitors position sensors and switches, while LIN/USART interfaces connect to the vehicle body network. The -40°C to +125°C operating temperature range handles under-dash thermal environments. Placed behind a 12V automotive rail with a 5V or 3.3V regulator, it executes switch-bounce filtering, debouncing, and actuator sequencing locally without burdening the central BCM.

設計ノート
Estimated: at VDD=3.3V, CPU=32MHz active, the PIC16LF1788-E/SO core current is typically in the single-digit mA range. For battery designs, leverage XLP sleep modes with retention current near 1 nA to extend standby life. Use the LF silicon variant when operating below 2.7V; the F variant cannot run below 2.3V without reset. Decouple VDD with 100 nF ceramic placed within 3 mm of the package pin, and add 10 uF bulk if the load is pulsed (e.g., radio transmission bursts).
The 28-SOIC package has a thermal resistance (theta_JA) typically around 80 C/W on a standard 2-layer PCB. Provide a ground copper pour under the package to assist thermal dissipation and reduce ground bounce. Keep the ICSP lines (RB6/RB7) routed with short traces to the programming header to ensure reliable in-circuit programming; do not place series resistors above 1 kohm on these pins or programming may fail. Leave MCLR/VPP accessible via a pull-up resistor to VDD (typically 10 kohm).
Do not exceed the absolute maximum VDD of 4.0V on the LF variant (5.5V on F variant). Ensure the PICKit or ICD debugger is set to the correct device family ID; selecting PIC16F1788 firmware for an LF silicon may erase the calibration area. The LF and F silicon have slightly different low-voltage reset thresholds, so brown-out detection must be configured to the appropriate BOR setting for the chosen part. Finally, when migrating from -E to -I temperature grade, expect slightly lower high-temperature margin.
