PIC16LF1827-E/SS - 8-bit 32MHz MCU 7KB Flash 20-SSOP | Microchip
MPN： PIC16LF1827-E/SS ✓ 啟用中PIC16LF1827-E/SS 概覽
A microcontroller (MCU) is an integrated circuit containing a CPU, program memory (Flash/ROM), data memory (RAM), and configurable peripherals on a single die. In the taxonomy of semiconductors, an MCU belongs to the embedded processor category, which sits under microcontrollers and digital signal controllers, and ultimately under the broader class of logic ICs and integrated circuits. The PIC16LF1827 specifically integrates the PIC mid-range core, peripherals, and XLP power management so designers can implement complete mixed-signal sensing products with a single 20-pin device.
Key features include the integrated 32 MHz internal oscillator, an mTouch capacitive sensing module for touch buttons/sliders, a data signal modulator, MI2C/SPI/EUSART with auto-baud, two ECCP and two CCP enhanced/capture/PWM modules, and a 10-bit ADC with computation. The 20 SSOP pinout exposes 16 I/O pins, an MCLR reset, and the ICSP programming/debug interface, giving designers a generous peripheral set in a compact footprint.
Typical applications include capacitive touch user interfaces, low-power sensor nodes, white-goods control boards, battery-powered IoT end nodes, and portable consumer devices where the 1.8V minimum supply enables direct operation from a single Li-coin cell. The on-chip peripherals allow it to drive LEDs, read sensors over I2C/SPI, generate PWM, and wake up on interrupt with currents in the microamp range.
When designing with the PIC16LF1827-E/SS, ensure your supply voltage stays within 1.8V to 3.6V and budget the I/O current per the 25 mA sink/source limit. Use the ICSP interface and Microchip's MPLAB X IDE for programming and debugging.

典型應用
PIC16LF1827-E/SS 適用於 6 應用s: Capacitive Touch User Interface, Battery-Powered IoT Sensor Node, White-Goods Control Board, Portable Consumer Electronics, LED Lighting Control, Automotive Body and Lighting Modules.
Capacitive Touch User Interface
The PIC16LF1827-E/SS is a strong fit for capacitive touch user interfaces in appliances and consumer electronics. Its integrated mTouch module evaluates up to 16 sensor channels via charge-time measurement, eliminating the cost and PCB area of an external touch IC. The 7 KB Flash comfortably holds the touch pattern library plus PWM control routines for visual or haptic feedback. NanoWatt XLP sleep currents below 1 uA let the device remain in idle-touch scanning on a coin-cell battery for years. Operating down to 1.8V, it supports direct connection to a single Li cell without a boost converter.
推薦
Battery-Powered IoT Sensor Node
Designed for IoT sensor endpoints, the PIC16LF1827-E/SS combines 1.8V operation, sub-uA XLP sleep, and a 32 MHz core for intermittent processing. The 384-byte RAM is sized for short sensor bursts before backhaul transmission over EUSART or MI2C. Its data EEPROM provides non-volatile logging of calibration or event counters across power cycles. With the internal LFINTOSC and HFINTOSC, designers can drop the external crystal entirely, cutting BOM cost and current draw on a 3V coin-cell.
推薦
White-Goods Control Board
In washing machines, dishwashers, and microwave ovens, the PIC16LF1827-E/SS drives PWM-controlled motor and heater loads through its 2 ECCP and 2 CCP modules, while ADC channels read temperature and water-level sensors. The mTouch module allows sleek glass-front user interfaces without mechanical buttons. Industrial-grade EMI robustness and 1.8V-3.6V operation simplify power-supply design in appliances with auxiliary 3.3V rails. The 20-SSOP footprint is friendly to single-layer PCB layouts common in white-goods.
推薦
Portable Consumer Electronics
For toys, personal-care devices, and remote controls, the PIC16LF1827-E/SS keeps total BOM cost low via internal 32 MHz oscillator, internal pull-ups, internal voltage reference, and integrated touch sensing. The 7 KB Flash typically supports the entire product firmware including protocol stacks for IR/BLE control coordination. NanoWatt XLP technology extends battery life in idle by orders of magnitude compared to mid-range PIC parts without XLP. The 20-SSOP package is small enough for handheld form factors.
推薦
LED Lighting Control
The PIC16LF1827-E/SS PWM resources (2 ECCP, 2 CCP) drive multi-channel white, RGB, or tunable LED strings while the 10-bit ADC reads light or current-sense feedback for closed-loop control. I2C or SPI peripherals coordinate with downstream driver ICs or DMX transceivers. Operating from 1.8V-3.6V, the MCU fits LED drivers with 3.3V auxiliary rails. The Data Signal Modulator simplifies zero-cross detection for phase-cut dimmer boards.
推薦
Automotive Body and Lighting Modules
Within body-electronics or lighting accessories, the PIC16LF1827-E/SS provides fault-resilient operation thanks to its -40C to +125C extended temperature grade (E suffix) and nanoWatt XLP low-power modes for ignition-off quiescent draw. PWM channels dim interior lamps and the mTouch module accepts capacitive switches on door panels. Designers should validate AEC-Q100 conformance for safety-critical loads; for non-safety body-electronics it is a cost-effective, low-power option.

設計說明
Use a 100 nF decoupling capacitor as close to Vdd pin 7 as possible, plus a 10 uF bulk capacitor within 1 cm of the device. The LF1827's nanoWatt XLP technology keeps sleep current below 1 uA only when Vdd is clean; noisy rails force the ADC and reference into bias-correction. Estimated: at 1 mA active current, a 10 uF bulk cap holds Vdd above 3.0V for ~30 ms during a coin-cell voltage drop; size up if wireless activity is concurrent.
Route the ICSP pins RA0 (ICSPDAT) and RA1 (ICSPCLK) away from switching lines so they remain usable for in-circuit debug throughout production. The 20-SSOP package has a 0.65 mm lead pitch - ensure a 4-6 mil trace clearance and consider microvia escape for inner pads. Place the mTouch sensor electrodes on a separate ground island if used, with a 1.5 mm gap from any ground fill or copper pour to prevent parasitic capacitance.
Do not exceed the 25 mA absolute maximum I/O sink/source current per pin or the 200 mA Vdd supply current for the entire package. Configure unused I/O as outputs low (not high-z) to avoid floating-pin currents that can swap to several mA total. When migrating firmware between LF and F variants, double-check the brown-out reset threshold: the F1827 BOR threshold defaults are different and may trigger on 3.3V rails where the LF1827 is happy.
I2C rise time on SCL/SDA pins scales with the internal pull-up weak pull-up and external bus capacitance; for 400 kHz Fast-Mode, add external 4.7 kohm pull-ups even though the LF1827 has weak internal pull-ups. The SPI bus pins (RC4/RC5/RC6/RC7) are shared with ADC inputs, so disable ADC on those pins when SPI is active to avoid channel crosstalk. For high-speed PWM (16 MHz on ECCP), keep traces short and use grounded guard traces on the SSOP.
