PIC16F15345-E/GZ Overview
What is a PIC16 8-bit microcontroller? A PIC16 microcontroller is a RISC-based 8-bit MCU from Microchip's mid-range PIC family, offering low power consumption, deterministic interrupt response, and a rich peripheral set. Within the broader taxonomy, PIC16 belongs to: microcontroller -> 8-bit MCU -> RISC MCU -> PIC family -> embedded semiconductor. The PIC16F153xx sub-family adds Core Independent Peripherals (CIPs) that operate without CPU intervention and XLP features such as deep-sleep current in the nanoamp range, making the device suitable for battery-powered and energy-harvesting designs.
Key features include 4 PWMs, a hardware comparator, a 5/8-bit DAC, a 10-bit ADC, a Complementary Waveform Generator (CWG), 2 EUSART, and SPI/I2C interfaces. The 32MHz maximum CPU speed delivers up to 8 MIPS, sufficient for control loops and protocol handling. The 14KB Flash supports sizable application code, while the 1KB RAM accommodates moderate data buffers. On-chip CIPs offload tasks such as signal generation and timing, freeing the core for application logic.
Architecturally, the device uses an enhanced mid-range 8-bit CPU core with a hardware multiplier and a 14-bit instruction word. The XLP architecture integrates low-power Run, Idle, and Sleep modes with peripheral clock gating and a nanoWatt Power Manager. Analog blocks share a common analog MUX, allowing flexible routing of ADC, DAC, and comparator sources across device pins.
Typical applications include low-power IoT sensor nodes, consumer appliances, industrial control modules, and battery-powered instrumentation. The integrated CWG simplifies half-bridge and full-bridge drive of MOSFETs or LEDs, while the 2 EUSART peripherals enable simultaneous LIN or RS-485 communication in industrial nodes.
When designing with this MCU, budget I/O carefully: the 20-UQFN (4x4) package exposes a limited number of GPIO pins, so pin multiplexing matters. Use the MPLAB Code Configurator (MCC) to generate peripheral initialization code and pin maps, and verify the power budget against the application's active and sleep duty cycle.

Typical Applications
PIC16F15345-E/GZ is suitable for 6 applications: Battery-Powered IoT Sensor Node, Consumer Appliance Control Board, Industrial Sensor Interface Module, LED Lighting Driver and Color Controller, Automotive Body Electronics (Sub-Assembly), HMI Keypad and Display Interface.
Battery-Powered IoT Sensor Node
The PIC16F15345-E/GZ is a strong fit for battery-powered IoT sensor nodes due to its XLP nanoWatt technology and Core Independent Peripherals (CIPs). With 32MHz CPU speed delivering 8 MIPS and 14KB Flash for sensor processing code, the device can run an Idle+Sleep duty cycle in the nanoamp range while a peripheral event (timer, ADC, or comparator interrupt) wakes the core for a short measurement burst. The 2 EUSART peripherals support simultaneous sensor bus and backhaul communication. Compared with a Cortex-M0+ alternative, the PIC16F15345 consumes less sleep current and is cheaper in the UQFN-20 footprint, while its 14KB Flash is sufficient for typical edge sensor stacks including calibration tables and command parsers.
Recommended
Consumer Appliance Control Board
In consumer appliances such as coffee machines, blenders, and washing-machine sub-modules, the PIC16F15345-E/GZ integrates every major block: the CWG for half-bridge MOSFET drive, 4 PWMs for motor or valve control, the 10-bit ADC for thermistor or current sensing, and 2 EUSART for user-interface display communication. The 32MHz CPU easily handles PID-style control loops within microsecond update rates, while the 14KB Flash accommodates menu state machines and fault-recovery logic. Compared with a discrete analog control board, this single-chip solution reduces BOM cost, shrinks the PCB to the 4x4 UQFN-20 footprint, and improves EMI through hardware-driven switching rather than firmware-timed bit-banging.
Recommended
Industrial Sensor Interface Module
The PIC16F15345-E/GZ serves well in industrial 4-20 mA loop-powered sensor modules and isolated RS-485 nodes. Its 2.3V to 5.5V operating voltage lets it interface directly to 3.3V sensors and 5V RS-485 transceivers, while the 10-bit ADC and hardware comparator handle sensor front-end conditioning without external op-amps. The 2 EUSART peripherals enable simultaneous connection to a local HMI and a fieldbus master. Its -40C to +125C operating temperature range supports industrial deployments. Compared with a Cortex-M0 design, the PIC16F15345's deterministic interrupt latency and CIP-based timing reduce CPU load, leaving more headroom for the protocol stack on the same 14KB Flash.
Recommended
LED Lighting Driver and Color Controller
The PIC16F15345-E/GZ is well suited to smart LED drivers where the CWG and 4 PWMs generate multi-channel PWM dimming with hardware dead-band control, eliminating the CPU jitter that plagues firmware-only PWM approaches. The 5/8-bit DAC and comparator allow constant-current feedback loops for high-power LEDs, while the 14KB Flash stores color profiles, dimming curves, and DMX/Casambi protocol stacks. Its UQFN-20 (4x4) package fits inside the compact form factor of GU10 bulbs and architectural fixtures. Compared with a 32-bit ARM Cortex-M0 LED controller, the PIC16F15345 delivers lower BOM cost and lower sleep current while supporting full-color dimming through its hardware CIPs.
Recommended
Automotive Body Electronics (Sub-Assembly)
Within non-safety automotive sub-assemblies such as seat controllers, mirror adjusters, or ambient lighting modules, the PIC16F15345-E/GZ provides the LIN/EUSART communication, CWG-driven half-bridge outputs, and 10-bit ADC for position feedback that these designs require. Although the -E/GZ part is rated -40C to +125C and meets the temperature range, automotive safety-critical systems should use an AEC-Q100 qualified PIC variant. The 32MHz CPU and CIPs keep firmware simple and deterministic. Compared with an automotive ARM Cortex-M0 design, the PIC16F15345 offers comparable analog integration at a lower unit cost in the UQFN-20 footprint.
Recommended
HMI Keypad and Display Interface
The PIC16F15345-E/GZ powers compact human-machine interfaces such as membrane-keypad controllers and small character-LCD displays. Its 4 PWMs drive LED backlights and indicator LEDs, the EUSART interfaces with a host controller or a UART-driven display, and the 10-bit ADC reads potentiometers or rotary encoders. The 14KB Flash holds debounce logic, character maps, and menu state machines. Its UQFN-20 (4x4) footprint is small enough for in-panel mounting. Compared with an FPGA or ARM Cortex-M0 HMI controller, the PIC16F15345 delivers a leaner BOM and faster firmware development through MPLAB Code Configurator.

Design Notes
Estimated: at VDD=3.3V, CPU active at 32MHz, the PIC16F15345-E/GZ typical active current is roughly 2-3 mA. In Sleep mode with peripherals disabled, nanoWatt technology brings current into the nanoamp range (typically <100 nA). For battery-life calculations, model the active duty cycle separately from sleep current, and verify against the datasheet IDD vs frequency curves for your exact VDD.
The 20-UQFN (4x4) package requires a PCB land pattern with a central thermal/ground pad. Stitch this central pad to the ground plane with multiple vias for thermal dissipation and electrical grounding. Place decoupling capacitors (0.1 uF and 1 uF ceramic) as close to the VDD pin (pin 7) as possible, and route the analog and digital ground regions back to a single point near the MCU to avoid ground loops with the analog ADC/DAC.
When using the ADC or DAC, isolate analog traces from PWM and digital switching lines. The UQFN-20 package has limited pin count, so plan pin multiplexing early with the MPLAB Pin Manager. Reserve one GPIO as a firmware-driven reset indicator or test point for production bring-up.
Do not drive the central exposed pad (EP) of the UQFN-20 with a signal trace - it must be soldered to the ground plane for thermal and electrical reasons. Configuring a pin as analog that is set as digital output (or vice versa) can cause a momentary contention current; initialize analog pins first, then outputs, when bringing the MCU out of Reset. The CWG dead-band control requires careful register sequencing - consult the PIC16F153xx family reference manual before enabling.
When routing EUSART or SPI signals at high baud rates from the UQFN-20 package, keep traces short and matched. The 32MHz CPU can drive SPI at up to roughly 8 MHz without DMA, but a ground reference beneath the SPI bus and a series resistor near the source pin will reduce ringing on long traces.
Compliance Information
RoHS and lead-free status inferred from Microchip's standard product policy for UQFN-20 surface-mount PIC16F family parts; AEC-Q100 not qualified for this E/GZ part - choose a Q-qualified PIC16F variant for automotive safety-critical designs.
