PIC16LF15354-E/MV - 8-bit MCU 7KB Flash 32MHz XLP | Microchip
MPN： PIC16LF15354-E/MV ✓ 啟用中PIC16LF15354-E/MV 概覽
An 8-bit microcontroller (MCU) is a compact, single-chip computer built around an 8-bit data path. It belongs to the broader family of microcontrollers, which are themselves a subcategory of embedded processors within semiconductors. 8-bit MCUs remain widely used in cost-sensitive, low-power, and deterministic applications because their instruction sets are simple, their tool chains are mature, and their interrupt latency is highly predictable.
Key features of the PIC16LF15354-E/MV include 4x PWM channels, a hardware Comparator, a 5-bit DAC, a 10-bit ADC with computation, a Complementary Waveform Generator (CWG), and a Memory Access Partition (MAP) feature for bootloader protection. The 28-pin UQFN (4x4 mm) package provides a small footprint suitable for space-constrained designs. XLP technology enables deep sleep currents in the nanoampere range, extending battery life in portable and energy-harvesting applications.
The device is built on an enhanced mid-range PIC core with a 14-bit instruction word and a hardware multiplier, balancing code density with deterministic execution. Its Intelligent Analog peripherals (ADC with computation, slope compensation, and burst averaging) and CIPs (CLC, CLC2, NCO, CWG) allow complex control loops to run without CPU intervention, freeing the core for application logic.
Typical applications include low-power IoT sensor nodes, battery-powered motor control, LED lighting controllers, capacitive touch user interfaces, automotive body electronics (with the matching -E automotive grade suffix), and consumer remote controls. Industrial sensor hubs and small home appliances are also strong fits given the broad peripheral mix.
Design consideration: Because the UQFN (4x4) package has an exposed thermal pad that doubles as the device ground, the PCB land pattern must include a center thermal pad with multiple thermal vias to a continuous ground plane. Omitting these vias will increase junction temperature and degrade ADC accuracy at high ambient temperatures.

典型應用
PIC16LF15354-E/MV 適用於 7 應用s: Low-Power IoT Sensor Nodes, LED Lighting Controllers, Capacitive Touch User Interface, Battery-Powered Motor Control, Industrial Sensor Hubs, Consumer Remote Controls, Small Home Appliances.
Low-Power IoT Sensor Nodes
The PIC16LF15354-E/MV's nanoWatt XLP technology (deep-sleep currents in the nanoampere range) makes it ideal for battery-powered IoT sensor nodes that must run for years on a coin cell. The 10-bit ADC with computation handles direct sensor signal conditioning, while the 2x EUSART, SPI, and I2C interfaces allow connection to wireless modules such as LoRa, BLE, or sub-GHz transceivers. The 28-UQFN (4x4 mm) footprint fits inside sensor puck housings.
推薦
LED Lighting Controllers
The PIC16LF15354-E/MV integrates 4x PWM channels and a Complementary Waveform Generator (CWG) that together produce flicker-free LED drive signals and dead-band control for half-bridge MOSFET drivers. The hardware comparator and 5-bit DAC enable closed-loop current regulation for constant-current LED strings. At 32 MHz CPU clock, the device runs PID color-mixing loops well within instruction-cycle timing budgets.
推薦
Capacitive Touch User Interface
With the Core Independent Peripherals (CIPs) and Intelligent Analog suite, the PIC16LF15354-E/MV implements capacitive touch buttons, sliders, and proximity sensing without burdening the CPU. The mTouch peripheral library and CVD (charge-virtual-time) techniques detect electrode capacitance changes through noise-tolerant scanning - ideal for kitchen appliances, consumer remotes, and industrial control panels.
推薦
Battery-Powered Motor Control
The PIC16LF15354-E/MV drives small DC motors, BLDC fans, and stepper drivers via its 4x PWM outputs, hardware comparator for back-EMF sensing, and CWG for half-bridge drive. XLP technology keeps idle power below microamp thresholds between motion events, critical for battery-operated toys, personal care devices, and handheld tools. The 7 KB Flash holds lookup-table-based trapezoidal commutation algorithms.
推薦
Industrial Sensor Hubs
The PIC16LF15354-E/MV aggregates multiple analog sensors over its 10-bit ADC with computation, then bridges to a PLC or industrial bus via UART, SPI, or I2C. The hardware CIPs implement local filtering, debouncing, and thresholding without CPU cycles. The -40C to +125C industrial temperature grade supports factory-floor, HVAC, and outdoor enclosure deployment.
推薦
Consumer Remote Controls
The PIC16LF15354-E/MV runs IR-protocol encoders (RC5, NEC, SIRC) and capacitive-touch button scanning in deep sleep, waking only on key press or IR receive. With XLP technology, the MCU draws nanoamps in sleep while still handling capacitive touch via the CIPs, extending battery life of TV remotes, AC controllers, and presentation clickers to multi-year durations on a single coin cell.
推薦
Small Home Appliances
The PIC16LF15354-E/MV fits the BOM cost target for coffee makers, blenders, slow cookers, and other small appliances. Its motor-control peripherals (PWM, CWG, comparator) drive pumps and fans, while the ADC with computation reads thermistor inputs. The Memory Access Partition (MAP) feature lets a manufacturer ship a single firmware image that supports multiple product SKUs.

主要差異化特點
- Memory Access Partition (MAP) for bootloader protection (對比PIC16LF15344-E/MV)
- Optimal balance of Flash and cost (對比PIC16LF15355-E/MV)
- Low-voltage LF variant for battery-powered designs (對比PIC16F15354-E/MV)
設計說明
The 28-UQFN (4x4 mm) package has an exposed thermal pad that doubles as the device ground. The PCB land pattern must include a center thermal pad with at least 5 thermal vias (0.3 mm drill, 0.5 mm pitch) connecting to a continuous ground plane. Omitting these vias will increase theta_JA significantly, raising junction temperature and degrading ADC accuracy at high ambient temperatures (above 85C).
Place the decoupling capacitor (100 nF X7R) within 2 mm of the VDD pin. Add a 10 uF bulk capacitor near the IC. For ADC accuracy, separate analog and digital VDD traces, and route analog signals away from PWM outputs and clock lines. The exposed thermal pad (EP) must be soldered to the PCB thermal pad with a void-free solder joint for both electrical grounding and thermal dissipation.
Estimated - based on datasheet typical use: when migrating from PIC16F to PIC16LF family, verify that your maximum VDD is below the LF variant's ceiling. The LF variant has a lower VDD max than the F variant; using it above its rating will damage the device. Also confirm that the oscillator configuration bits match the actual crystal or external clock - mismatches cause brown-out resets or unstable operation.
