PIC16LF15356-E/ML Visão geral
What is an 8-bit microcontroller? An 8-bit MCU (microcontroller unit) is a single-chip computer that processes data in 8-bit chunks and integrates CPU, Flash program memory, RAM, EEPROM, and peripherals such as timers, ADC, communication interfaces, and I/O on a single die. PIC16 microcontrollers from Microchip are widely used in cost-sensitive and low-power embedded applications, sitting in the broader hierarchy of microcontroller -> embedded controller -> semiconductor IC. The LF variant operates across a wider voltage range with lower current draw than the standard F version.
Key features include 4 PWM channels, a hardware comparator, a 5-bit/10-bit DAC, a 10-bit ADC, a Complementary Waveform Generator (CWG), 4 Configurable Logic Cells (CLC), 2 EUSART modules, SPI, and I2C. The XLP technology enables deep-sleep currents in the nanoampere range, suitable for battery-powered IoT endpoints. The device operates across a 1.8V to 3.6V supply range (LF variant) and includes integrated oscillators and on-chip debug support.
Technical depth: The PIC16LF15356 uses a 14-bit instruction set with hardware multiplier, deterministic interrupt response, and Peripheral Pin Select (PPS) for flexible signal routing. The CWG and CLC blocks implement custom waveform generation and combinatorial logic without CPU intervention, freeing the core for application code.
Typical applications include IoT sensor nodes, low-power wireless devices, home appliances, LED lighting controllers, battery chargers, and small consumer electronics. The wide peripheral set and small QFN-28 footprint make it suitable for space-constrained designs.
Design consideration: Place a 0.1uF decoupling capacitor close to each VDD pin and a 1uF bulk capacitor on the main supply rail. Use the exposed pad (EP) for thermal relief and ground connection by stitching multiple vias to the inner ground plane.

Notas de projeto
Place a 0.1uF ceramic decoupling capacitor within 3mm of each VDD pin (the PIC16LF15356-E/ML has VDD on pins 5 and 28) and a single 1uF to 10uF bulk capacitor on the main supply rail. For battery applications using XLP sleep modes, the leakage of the bulk capacitor matters - choose a ceramic with low-leakage dielectric (X7R or X5R) rather than electrolytic. Add a 10kohm pull-up on MCLR (pin 25) to VDD to ensure reliable reset behavior.
Estimated: The 28-QFN (6x6) package thermal resistance theta_JA is approximately 35 C/W on a 4-layer JEDEC test board. The PIC16LF15356-E/ML typically dissipates under 50mW even at 32MHz active, so no heatsink is needed. However, the exposed pad (EP) MUST be soldered to the PCB ground plane with multiple thermal vias (typically 9-16 vias in a 3x3 grid) to provide both thermal relief and a low-inductance ground reference for clean ADC measurements.
Route the ICSCLK and ICSDAT signals (RB6/RB7) away from high-frequency switching nodes and keep trace lengths under 50mm for reliable in-circuit serial programming. Place the ICSP connector on the board edge for production-line access. The analog inputs (RAx, RCx) used for ADC should be isolated from digital switching traces with a ground guard ring; the AVSS pin (if exposed) must connect directly to the analog ground plane.
Do not configure a PWM output on a pin also used as a debugging peripheral without first disabling the debug module, or the PWM signal will be corrupted during debug sessions. The Peripheral Pin Select (PPS) feature allows flexible signal routing but each peripheral function can only be assigned to one pin at a time - duplicate assignments are silently ignored. When using the ADC, allow at least 1us settling time after switching channels before initiating a conversion.
Informações de conformidade
RoHS and REACH compliant per Microchip product declarations. Not AEC-Q100 qualified - the E temperature grade does not imply automotive qualification. For AEC-Q100 needs, select a specifically Q100-qualified PIC16 part.
