PIC16LF19195-E/MR Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that integrates a CPU core, non-volatile program memory, working RAM, and a mix of analog and digital peripherals. The PIC16 family uses a RISC-style Harvard architecture that executes most instructions in one oscillator cycle, giving the PIC16LF19195-E/MR roughly 8 MIPS at its 32 MHz top speed. It sits inside the larger power-management-aware hierarchy of eXtreme Low-Power (XLP) PIC MCUs and shares a toolchain (MPLAB X IDE + XC8) with all modern PIC16 devices.
Key features include eXtreme Low-Power (XLP) operation with active current typically below a few hundred µA/MIPS, an integrated LCD driver with selectable charge pump and high-current segment pins for direct backlight driving, a battery-backed Real-Time Clock/Calendar (RTCC), and Core Independent Peripherals (CIPs) such as CWG, CCP, PWM, SMT and ZCD that offload timing tasks from the core. The 12-bit ADC2 with internal channels, a 5-bit DAC, low-power comparators (LP COMP) and Peripheral Pin Select (PPS) provide flexible analog and pin routing. The 64-pin QFN exposes up to 58 I/O with PPS remapping.
Typical applications include battery-powered thermostats and utility meters, remote controls and home automation keypads with segmented LCD, medical monitoring handhelds (glucometers, pulse oximeters), industrial sensor transmitters with RTCC-stamped logs, and IoT edge nodes driving small character displays. The LCD charge pump lets the design keep the display active even when the battery voltage falls below the LCD threshold.
When designing with this part, budget 1 square inch of copper under the exposed pad for thermal relief, keep analog traces short, and place the 0.1 µF VDD bypass cap within 3 mm of the supply pin. Use MPLAB X IDE with the XC8 compiler and select the appropriate Low-Power Sleep mode (Retention Sleep vs. full Sleep) to fully exploit the XLP benefit in battery applications.

Typical Applications
PIC16LF19195-E/MR is suitable for 6 applications: Battery-Powered Thermostat with LCD, Medical Glucose / Pulse Meter, Industrial Sensor Transmitter with RTCC Logging, Remote Control / Home Automation Keypad, Smart Utility Meter (Electric / Water / Gas), IoT Edge Node with Character LCD.
Battery-Powered Thermostat with LCD
The PIC16LF19195-E/MR is well suited to wall-mounted thermostats running from two AA cells because it operates down to 1.8 V while still driving the LCD through the integrated charge pump. With 14 KB Flash, 1 KB SRAM and 256 B EEPROM, the firmware fits the room-temperature calibration tables, weekly schedule and a CIP-driven state machine without external memory. Per the Microchip datasheet, the device consumes only a few hundred µA/MIPS in active mode and falls into the nA range in Retention Sleep, extending battery life over multi-year intervals on the segment display. The RTCC provides wall-clock timekeeping across power cycles so the schedule is preserved when the user replaces the cells.
Recommended
Medical Glucose / Pulse Meter
The 12-bit ADC2 with internal channels and 5-bit DAC on the PIC16LF19195-E/MR supports electrochemical strip reading or pulse-oximetry front-end conditioning in a single-chip medical hand-meter design. The XLP active current (a few hundred µA/MIPS) lets the device wake, take a measurement, run the math, drive the segmented LCD, and return to Sleep within the patient's expected battery-life target. CIPs such as SMT and CCP handle strip timing, while PPS remaps the analog channels to clean PCB traces, reducing BOM cost. The 64-pin QFN footprint also leaves generous PCB area for an isolated analog front-end.
Recommended
Industrial Sensor Transmitter with RTCC Logging
For a 4-20 mA or wireless HART-style transmitter, the PIC16LF19195-E/MR pairs a 12-bit ADC2 for sensor conditioning with the RTCC block to time-stamp every measurement into the 256 B EEPROM (sufficient for circular buffering at 1 sample/min for >4 hours). The CWG peripheral synthesizes dead-band-controlled PWM for an analog output stage, while the integrated low-power comparator (LP COMP) implements brown-out and over-temperature hardware protection. The 1.8-3.6 V VDD range is compatible with industrial 24 V rails stepped down through a low-quiescent LDO, and the E-grade -40 to +125C spec covers outdoor enclosures.
Recommended
Remote Control / Home Automation Keypad
A handheld remote or wall keypad benefits from the PIC16LF19195-E/MR's integrated LCD driver with charge pump, which lets the segment display operate even when VDD droops during a low-battery event. The 12-bit ADC2 reads battery voltage directly (no external resistor-divider ADC needed), and CIPs like CWG and SMT generate IR carrier modulation in hardware, offloading the CPU and extending battery life. PPS remaps the segment and key-scan pins so the same 64-QFN package can be reused across multiple product SKUs with different keypad layouts.
Recommended
Smart Utility Meter (Electric / Water / Gas)
Utility meters running from lithium primary cells are an ideal match for the PIC16LF19195-E/MR: the LCD charge pump keeps the segment display visible from a nearly depleted 2.7 V cell, the RTCC tracks time-of-use tariffs, and the 256 B EEPROM retains logged data for >20 years. The ZCD peripheral synchronizes mains-voltage crossings for power-meter AFE sampling without CPU intervention, and the integrated low-power comparator provides brown-out protection. The 64-pin QFN leaves enough I/O to drive both a segmented LCD and an optical tamper-detection sensor simultaneously.
Recommended
IoT Edge Node with Character LCD
For battery-powered IoT sensors that must show status on a 2x16 character LCD without a backlight, the PIC16LF19195-E/MR provides both the 8-bit MCU and the segment/character LCD drive with a charge pump that maintains the display down to ~1.8 V. With 14 KB Flash and 1 KB SRAM, the firmware fits an interrupt-driven sub-GHz radio state machine plus display refresh. The 12-bit ADC2 samples analog sensors, the SMT peripheral times low-power radio windows, and PPS frees the designer from rigid pin assignments. The /MR QFN-64 footprint allows direct PCB reuse across multiple product variants.

Key Differentiators
- Integrated LCD driver with charge pump keeps display visible down to 1.8 V (vs PIC16F19195-E/MR)
- Pin-compatible upgrade path to higher-memory siblings (vs PIC16LF19196-E/MR)
- Wider operating temperature than I-grade (-40 to +125 C vs -40 to +85 C) (vs PIC16LF19195-I/MR)
Design Notes
Estimated: at 32 MHz / 3.3 V with all peripherals active, typical active current is a few hundred µA/MIPS, giving less than 10 mW of dissipation in the 64-pin QFN. The exposed thermal pad (EP) of the /MR package must be soldered to a continuous copper pour of at least 1 square inch to keep junction rise below 20 C in enclosed industrial enclosures. Avoid cutting the EP plane under the analog traces; instead, route analog signals over a separate inner layer or use guard traces tied to AVSS. E-grade -40 to +125C operation is supported only when the EP is properly soldered.
Place the 0.1 µF VDD bypass capacitor within 3 mm of the VDD/VSS pins (pin 61 and pins 9/18/35/56 in the 64-QFN land pattern). The VCAP decoupling capacitor (pin 57) for the LCD charge pump regulator must be a low-ESR 1 µF ceramic placed directly on the VCAP node; this is a critical bypass for stable charge-pump operation below 2.0 V. Keep the LCD bias lines (VLCD1/2/3, pins 58-60) short and routed over a ground pour to minimize injection of bias ripple into the analog channels.
Do not connect an external pull-up on MCLR (pin 64) without a series resistor; the MCLR pin is also used as an ICD high-voltage entry and a direct high-voltage signal can damage programming mode. When migrating from PIC16LF19195 to PIC16F19195, verify that VDD never drops below 2.3 V during deep sleep wake-up, because the F-variant brown-out reset (BOR) may not release until that threshold. Finally, the PPS registers must be unlocked before configuration; forgetting to clear PPSLOCK causes peripheral outputs to appear silent.
