PIC16LF1619T-I/SS - 14KB Flash 32MHz 8-bit MCU | Microchip
MPN： PIC16LF1619T-I/SS ✓ 啟用中PIC16LF1619T-I/SS 概覽
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory (Flash), volatile data memory (SRAM), and a rich set of peripherals (timers, A/D converter, comparators, communications, PWM) into one IC. Within the broader taxonomy it sits between discrete microprocessors and system-on-chip (SoC) devices, and the PIC16LF1619 belongs to the 8-bit MCU class, while the LF sub-family targets energy-constrained products. PIC MCUs use a RISC Harvard architecture with a 14-bit instruction word that delivers deterministic interrupt latency.
Key features of this part include 14 KB (8K × 14) self-programmable Flash, 1 KB SRAM, 10-bit A/D converter, multiple 16-bit timers, configurable logic cell (CLC), signal measurement timer (SMT), complementary waveform generator (CWG) and on-chip 32 MHz internal HF oscillator. The 'T' suffix denotes Tape & Reel packaging for high-volume assembly lines, while the 'I' temperature grade covers the industrial -40°C to +85°C range. The SSOP-20 footprint is a popular 0.65 mm-pitch surface-mount package that is compatible with standard hand-soldering and reflow processes.
Typical applications for the PIC16LF1619T-I/SS include consumer appliance control, LED lighting drivers, sensor nodes, battery-powered IoT edge devices, and low-cost motor control loops. Designers select it for its combination of low power, integrated analog, and small-footprint SSOP - allowing direct PCB migration without a BGA or QFN. When choosing this part, verify that the SSOP-20 land pattern matches your PCB footprint and that the application fits within the 14 KB Flash / 1 KB SRAM envelope, or move to the larger-memory PIC16(L)F161x siblings if more code space is required.

典型應用
PIC16LF1619T-I/SS 適用於 6 應用s: Battery-Powered IoT Sensor Node, LED Lighting & Backlight Controller, Consumer Appliance Control (White Goods), Portable Wearable Health Device, Small BLDC / DC Motor Control, Industrial Sensor Transmitter (4-20 mA / 0-10 V).
Battery-Powered IoT Sensor Node
The PIC16LF1619T-I/SS is well suited to intermittent-duty IoT sensor nodes because its XLP (eXtreme Low Power) sleep currents sit in the nanoampere range, letting a 3 V coin cell last multiple years between replacements. The 10-bit A/D converter acquires analog sensor data (temperature, voltage, gas) directly without an external ADC, while PPS routing allows the SPI/I²C interface to a wireless transceiver to be remapped for compact PCB layout. The 14 KB Flash comfortably fits a custom protocol stack with OTA hooks. Designers should pair this MCU with a low-quiescent LDO and an SPI sensor to maximize battery life.
推薦
LED Lighting & Backlight Controller
The PIC16LF1619T-I/SS drives constant-current LED strings using its Complementary Waveform Generator (CWG) and 16-bit PWM timers, eliminating the need for an external LED driver IC. The CLC and SMT peripherals implement closed-loop current regulation in hardware, offloading the CPU and reducing firmware complexity. The 1.8-3.6 V supply range makes the part compatible with single-cell Li-ion or 2× AA battery packs used in portable luminaires. Engineers should use the internal 32 MHz oscillator and enable PWM fault shutdown for open-LED protection.
推薦
Consumer Appliance Control (White Goods)
In washing machines, dishwashers and microwave ovens the PIC16LF1619T-I/SS serves as the user-interface and motor-timer controller, leveraging its 14 KB Flash for state-machine firmware and 18 I/O pins for keypad and 7-segment LED multiplexing. The 10-bit converter reads thermistor inputs for temperature regulation, while PWM outputs drive triac-based heater or valve control. The industrial -40 °C to +85 °C grade is a strong fit for appliances that experience thermal stress near ovens or motors. Pin compatibility with the PIC16LF161x family simplifies firmware reuse across product variants.
推薦
Portable Wearable Health Device
Wearable fitness bands and pulse-oximeter patches can use the PIC16LF1619T-I/SS as the always-on low-power MCU, taking advantage of its XLP-grade sleep current under 50 nA to extend battery life for weeks at a time. The 10-bit ADC digitizes photodiode current from a PPG (photoplethysmography) sensor, while the SMT peripheral captures pulse timing with hardware-level precision. The SSOP-20 footprint is a strong match for the slim geometry of wrist-worn devices, where board height is constrained. Design tip: use deep sleep + watchdog wake for heart-rate sampling every 10 seconds.
推薦
Small BLDC / DC Motor Control
For small brushless-DC or brushed-DC motors used in fans, pumps, and toys the PIC16LF1619T-I/SS integrates a 10-bit ADC, PWM, CWG and SMT that together implement sensorless commutation or tachometer feedback in firmware. The 32 MHz core delivers sufficient MIPS for field-oriented control (FOC) of sub-50 W motors, and the 1.8-3.6 V range suits battery-powered cordless tools. Pin compatibility with the broader PIC16LF161x family enables the same PCB to host a higher-memory variant if algorithm complexity grows.
推薦
Industrial Sensor Transmitter (4-20 mA / 0-10 V)
Two-wire 4-20 mA loop-powered sensor transmitters benefit from the PIC16LF1619T-I/SS's low supply current and 1.8 V minimum operating voltage, allowing it to derive regulated power from the loop itself. The 10-bit ADC directly samples RTD, thermocouple or strain-gauge bridges, while the configurable logic cell (CLC) implements hardware gain/offset correction that offloads the CPU. The industrial -40 °C to +85 °C temperature grade satisfies process-industry environmental requirements. Designers should pair this MCU with a low-drift op-amp such as the MCP6V51 for accurate signal conditioning.

主要差異化特點
- 14 KB Flash with 1 KB SRAM in a tiny SSOP-20 footprint (對比PIC16LF1618T-I/SO)
- Industry-low XLP sleep current under 50 nA typical (對比PIC16F1619T-I/SS)
- Hardware CWG, CLC and SMT peripherals integrated on-die (對比PIC16LF1509T-I/SS)
設計說明
The PIC16LF1619T-I/SS draws the lowest quiescent current when idle in Sleep mode (typically <50 nA with WDT off). For battery-life-sensitive designs, gate peripherals such as the ADC and CWG off in firmware before entering Sleep, and use a hardware wake source such as IOC (interrupt-on-change) or the WDT for periodic sampling. Decouple VDD with a 100 nF X7R ceramic placed within 5 mm of the pin 16/20 power pads.
Use the SSOP-20 land pattern from the Microchip package specification document, not the SOIC-20 pattern. The 0.65 mm pitch SSOP requires tighter solder-mask openings than SOIC; confirm your PCB house supports 0.4 mm solder dams. Place a 4.7 µF bulk + 100 nF bypass combination on VDD and a single 100 nF on AV-DD-capable VDD pin if used for ADC reference.
When using the 10-bit ADC, switch the I/O pin to analog mode before the conversion and back to digital after sampling to avoid digital noise coupling into the ADC sample-and-hold. For ratiometric measurements, drive the sensor excitation from the same VDD rail that powers the MCU, and use the internal bandgap reference rather than VDD when absolute accuracy is required.
Do not exceed the absolute maximum VDD of 4.0 V (datasheet). Programming the configuration words with the wrong oscillator selection will leave the MCU running from an uncalibrated source - always verify OSCCON with the debugger. The PPS unlock sequence (PPSLOCKED bit) must be cleared before remapping peripherals; failure to do so will silently ignore the remap.
