PIC16F19156-E/SP 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a configurable set of peripherals (ADCs, timers, communication blocks, I/O). The PIC16F19156 family sits in the 8-bit PIC16 hierarchy under the broader PIC microcontroller taxonomy within Microchip's product tree. XLP variants are engineered for ultra-low-power battery applications, often using nanoWatt XLP technology to extend idle-current endurance.
Key features include integrated segmented LCD drive (up to 116 segments), a 12-bit ADC2 with computation, a 5-bit DAC, low-power comparator, Zero-Cross Detect (ZCD), Complementary Waveform Generator (CWG), SMT (Signal Measurement Timer), RTCC, Hardware Limit Timer (HLT), Windowed WWDT, PWM, CCP, Peripheral Pin Select (PPS) and Power-Managed modes. The high-current I/O pins can directly drive LCD backplanes or external power components.
Typical applications cover battery-powered LCD consumer devices, industrial automation HMIs, low-cost instrumentation, and consumer appliances. An integrated charge pump and XLP sleep currents in the nano-ampere class make the part especially suited to mains-free product categories where long battery life and a built-in display matter more than raw CPU throughput.
When designing with this device, ensure the configured system clock stays within the 2.5V-5.5V VDD range for full 32 MHz operation; below 2.5V the maximum fOSC derates. Decouple VDD with a 100 nF ceramic close to each power pin and place the ICD 3/4 or PICkit programmer footprint so firmware can be updated without board rework.

主な用途
PIC16F19156-E/SP の用途: 6 件s: Battery-Powered LCD Meter, Industrial HMI / Thermostat, Consumer Appliance Control, Portable Medical / Wellness Monitor, IoT Sensor Edge Node, Automotive Accessory (Non-Safety).
Battery-Powered LCD Meter
The PIC16F19156-E/SP fits battery-powered LCD metering because it integrates both a segmented LCD driver (up to 116 segments) and an on-chip charge pump, removing the need for an external LCD bias generator. With 28 KB of Flash the device holds a meter application plus RTCC-based timekeeping plus 256 bytes of EEPROM for tariffs and calibration constants. nanoWatt XLP sleep currents extend coin-cell life; the 32 MHz core keeps ADC2 sample loops fast enough for power-quality measurements on CT-based front ends.
おすすめ
Industrial HMI / Thermostat
The PIC16F19156-E/SP serves industrial thermostats and HMIs where a segmented LCD plus tactile buttons replace more expensive TFT panels. The 12-bit ADC2 with computation oversamples temperature sensors directly, the CWG block drives TRIAC/zero-cross switching, and ZCD synchronises with the mains cycle for low-RFI dimming. PPS remaps digital functions to spare I/O so PCB layout stays clean even with mixed button/LED/LCD signals. XLP sleep extends battery-backed operation after mains loss.
おすすめ
Consumer Appliance Control
For washing machines, dishwashers, microwave ovens, and rice cookers, the PIC16F19156-E/SP provides enough Flash for menu-driven state machines and the LCD driver eliminates an external display ASIC. The high-current I/O pins can sink LED backlights directly, while SMT and CCP measure motor RPM and PWM outputs. ZCD and CWG support AC-line dimming and synchronous rectification. The extended -40C to +125C grade covers appliance thermal environments without special screening.
おすすめ
Portable Medical / Wellness Monitor
The PIC16F19156-E/SP suits portable medical and wellness devices that pair a segmented LCD with low-power sensors such as temperature, pulse-oximeter front ends, and load-cell scales. The 12-bit ADC2 plus 5-bit DAC and low-power comparator form a complete analog front end in silicon, reducing BOM cost. XLP idle lets a small Li-ion cell run weeks between charges. The extended temperature grade and stable EEPROM storage support clinical logging requirements within IEC 61010 consumer-safety envelopes.
おすすめ
IoT Sensor Edge Node
In IoT edge nodes that need a local LCD status display alongside sensor sampling, the PIC16F19156-E/SP combines Cortex-class 8-bit compute with on-chip LCD plus CIPs. SMT measures pulse widths from ultrasonic or flow sensors; CCP captures encoder feedback; RTCC schedules sleep/wake cycles; HLT and WWDT provide hardware-managed safety timers. PPS keeps I/O remappable so adding a wireless module does not require a redesign. XLP nanoWatt sleep enables multi-year battery life on coin cells.
おすすめ
Automotive Accessory (Non-Safety)
For non-safety automotive accessories such as tire-pressure checkers, garage-door openers, interior LED drivers, and aftermarket gauges, the PIC16F19156-E/SP supplies the integrated LCD plus analog and CIP blocks. The 12-bit ADC2 and CWG simplify motor and dimmer control loops, and the extended -40C to +125C temperature grade handles cabin and engine-bay environments. Designers needing full AEC-Q100 should migrate to PIC16F19156-E/SP-Q1; the standard -E/SP is typically used for non-safety accessory modules.

設計ノート
Decouple each VDD pin (pins 19 and 28 on 28-SPDIP) with a 100 nF X7R ceramic placed within 5 mm of the package. Add a bulk 10 uF tantalum or aluminum-polymer cap near the regulator output for LCD-segment switching transients. Place a ferrite bead or small inductor on the VDD trace if the board shares a noisy rail with motors or relays; the PIC16F19156-E/SP noise immunity improves measurably when analog and digital rails are decoupled separately. Estimated: total bulk decoupling ~ 10 uF per rail, sized for worst-case LCD-segment inrush.
Do not exceed 5.5 V on any pin - the PIC16F19156-E/SP is not 5V-tolerant on analog inputs when VDD is below 5V. Always configure the PPS registers before enabling peripherals, and disable unused peripherals via PMD (Peripheral Module Disable) to lower quiescent current. Watch for accidental MCLR enable in code; if MCLR is disabled, provide an external reset supervisor or RC. Finally, keep firmware under 28 KB Flash - the linker will error if it exceeds.
Route the LCD segment traces with the COM (backplane) signals in a tree-style trunk to equalize capacitance on each segment - mismatched segment loading produces visible ghosting. Keep analog inputs (ADC2, comparators) short and away from PWM outputs and switching nodes. Reserve a 5-pin ICSP header footprint (VDD, VSS, MCLR, PGC, PGD) even on production boards so firmware updates are possible without rework. Estimated: minimum trace-to-trace clearance 0.2 mm for 5V industrial assemblies.
