PIC16F19155-E/SO 概述
An 8-bit microcontroller (MCU) is a self-contained processor that integrates a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and peripherals on a single die. Within the broader taxonomy, the PIC16F19155 belongs to the PIC16 family -> 8-bit PIC microcontroller family -> Microchip 8-bit MCU portfolio -> embedded computing. eXtreme Low-Power (XLP) technology is Microchip's branded suite of low-power design techniques that target battery-powered applications where quiescent current, sleep current, and wake-up time are critical.
Key features include integrated segmented-LCD drive (up to 64 segments), a charge pump for contrast, 12-bit ADC2 with computation, a 5-bit/10-bit DAC, low-power comparator, ZCD, CWG, CCP, PWM, and Peripheral Pin Select (PPS) for flexible signal routing. The device targets the 2.3V to 5.5V operating range and supports temperatures up to +125°C in the -E industrial grade, making it suitable for harsh environments and battery applications where extended temperature and low sleep current are required.
The PIC16F19155 architecture combines a RISC-based PIC16 core with Core Independent Peripherals (CIPs) that operate without CPU intervention, freeing the core for power management and decision logic. Intelligent Analog integration places the ADC, DAC, comparators, and voltage reference on-chip, enabling sensor interfaces and signal conditioning in a single device.
Typical applications include battery-powered LCD-display devices (thermostats, blood-pressure monitors, portable instrumentation), IoT sensor nodes, low-power metering, and human-machine interfaces with segment LCDs. The integrated charge pump allows direct drive of LCD glass at low VDD.
When designing with this part, leverage PPS to remap digital peripherals post-PCB-layout and use the ADC2 with computation for hardware-averaged acquisitions to keep the CPU in sleep. For battery applications, verify the sleep current in the exact temperature and peripheral-state combination that matches your duty cycle.

典型应用
PIC16F19155-E/SO 适用于 6 应用s: Battery-Powered Thermostats, Blood-Pressure / Portable Medical Monitors, IoT Sensor Nodes with Segment LCD, Smart Meters (Water / Gas / Electric), Human-Machine Interface (Segment LCD) Panels, Industrial Handheld Instruments.
Battery-Powered Thermostats
The PIC16F19155-E/SO fits battery-powered thermostats because of its 2.3-5.5 V supply range, integrated segmented-LCD driver with charge pump, and XLP sleep current below 1 µA typical. The on-chip charge pump enables glass contrast at low battery voltage without an external boost IC, which trims BOM cost and PCB area. The device drives up to 64 LCD segments directly, sufficient for room-temperature, setpoint, and mode indicators.
推荐
Blood-Pressure / Portable Medical Monitors
For portable medical monitors the PIC16F19155-E/SO delivers IEC 62304-friendly deterministic 8-bit performance, 12-bit ADC2 for pressure-signal acquisition, and Core Independent Peripherals that operate without waking the CPU. Its low-power sleep modes extend battery life across weeks of cuff-cycle duty, while the integrated DAC drives bridge-excitation or LCD references without an external component. The 28-SOIC package eases hand-rework in low-volume clinical builds.
推荐
IoT Sensor Nodes with Segment LCD
IoT sensor nodes benefit from the PIC16F19155-E/SO's XLP modes, integrated LCD charge pump, and PPS flexibility that lets engineers reassign peripheral pins post-layout. The 14 KB Flash holds a sensor-conditioning loop plus a small wireless-protocol snippet (e.g., LoRaWAN MAC). PPS remap support also reduces PCB re-spins when the BOM changes the wireless module pinout between hardware revisions.
推荐
Smart Meters (Water / Gas / Electric)
In smart-meter designs, the PIC16F19155-E/SO provides 12-bit ADC2 for metrology, RTC for time-stamping, segmented LCD for kWh / m³ / ft³ readouts, and RTCC for tamper logging. XLP sleep current below 1 µA enables 10-year battery life on a single lithium cell. The integrated ZCD supports zero-crossing detection for line-frequency metering, while CWG generates the LCD bias waveforms internally.
推荐
Human-Machine Interface (Segment LCD) Panels
HMI panels with character or graphic segment displays use the PIC16F19155-E/SO because the integrated LCD driver with charge pump supports contrast at low VDD, removing external boost hardware. The 24 available I/Os route to keypads, encoders, and status LEDs alongside the LCD. PPS allows the SPI/I2C buses to be mapped to spare pins, simplifying the PCB layout when the LCD glass pinout changes between models.
推荐
Industrial Handheld Instruments
Industrial handheld instruments rely on the PIC16F19155-E/SO's -40 °C to +125 °C industrial grade, integrated 12-bit ADC2 for transducer readout, and CWG for sensor excitation. The 28-SOIC package stands up to vibration and rework-friendly field repairs. PPS flexibility helps designers place ESD-protected I/O pins near connectors without disturbing the LCD glass pinout, and XLP modes support weeks of battery runtime per charge cycle.

设计说明
Estimated: with VDD=3.0 V and active mode at 32 MHz / 4 MIPS, the core draws roughly 2 mA; at 32 kHz LFINTOSC in sleep it falls to ~0.7 µA typical. Decouple VDD with a 0.1 µF ceramic placed within 5 mm of pins 18 and 28; add a 10 µF bulk cap on the same rail to support the LCD charge-pump transients. For battery applications, verify the wake-up-from-sleep time and residual ADC current in the exact peripheral-state combination used.
Estimated: route the LCD segment lines adjacent to one another on the PCB and keep them short to limit capacitive loading, which improves display contrast at low VDD. Place the MPLAB ICD4 / PICkit header on the RA0/RA1/RA7/RA3 (ICSP) pins and isolate it from analog traces. PPS flexibility lets you relocate SDA/SCL and other digital functions after layout, so leave spare GND-backed I/O pins near the I2C bus for late-stage reassignment.
Estimated: never exceed 5.5 V on VDD, including ESD events - a TVS diode on the supply rail is recommended for production. Do not skip the MCLR pull-up; without it the device can spuriously reset on noisy rails. Confirm the 256 B EEPROM endurance budget (typically 100k cycles) against the application's wear-out pattern, and place non-volatile parameters in Flash with wear-leveling if writes exceed the budget.
