PIC16LF15355T-I/ML - 8-bit MCU, 32MHz, 14KB Flash | Microchip
MPN: PIC16LF15355T-I/ML ✓ Hoạt độngPIC16LF15355T-I/ML Tóm tắt
A PIC microcontroller (MCU) is a compact programmable processor based on Microchip's proprietary Harvard architecture, widely used in embedded control applications. PIC16 devices sit in the mid-range 8-bit family, bridging simple 8-bit controllers and 32-bit ARM Cortex parts. They are commonly deployed in battery-powered, sensor-interface, and consumer designs where deterministic behavior, low cost, and low standby current are critical.
Key features include four 10-bit PWM modules, a 10-bit ADC with computation, two EUSART, two SPI/I2C, a 5-bit DAC, two comparators, four Configurable Logic Cells (CLC), a Complementary Waveform Generator (CWG) and a Numerically Controlled Oscillator (NCO). Peripheral Pin Select (PPS) remaps digital peripherals to almost any I/O pin, simplifying board layout. Core Independent Peripherals (CIPs) let timers, PWMs and the CWG run without waking the CPU, enabling sub-uA sleep modes.
Architecturally the device pairs a modified Harvard core with an 8-level hardware stack, a 32 MHz internal oscillator and Microchip's XLP nanoWatt design. The 14 KB Flash is partitioned to support bootloader + application code, and the unified MPLAB X IDE/MCC toolchain exposes the peripherals through graphical configuration. The 28-QFN footprint is also available on related PIC16LF153xx parts, allowing code-and-pin reuse across the family.
Typical applications include IoT sensor nodes, low-power wireless remotes, HVAC/thermostat controls, battery-powered medical wearables, LED lighting controllers, and consumer white goods. For designs targeting industrial automation, the 5V-tolerant I/O and dual-I2C simplify connection to sensors and EEPROMs. The combination of CIPs, PPS and XLP makes this MCU a strong fit for ASIL-A-style functional-safety designs where interrupt latency must be deterministic.
When designing with this part, allocate the PPS mapping early in firmware planning and use the CLC/CWG for hardware-only signal generation to keep the CPU asleep. Decouple VDD and VDDCORE with a 100 nF ceramic plus a 1 uF bulk capacitor placed within 5 mm of the pins.

Ứng dụng tiêu biểu
PIC16LF15355T-I/ML phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Nodes, Wireless Remote Controls / RF Keyfobs, HVAC and Thermostat Controllers, Low-Power Medical Wearables, Consumer White Goods and Appliance Control, LED Lighting and Driver Controllers.
Battery-Powered IoT Sensor Nodes
The PIC16LF15355T-I/ML is well suited for IoT sensor nodes thanks to Microchip's eXtreme Low-Power (XLP) technology, which holds sleep current in the hundreds of nanoamps with full RAM retention. The Core Independent Peripherals (4 CLCs, CWG, NCO) let the device wake on a sensor trigger, time a measurement, transmit, and return to sleep without waking the CPU. The 1.8-3.6 V range accepts a single Li-Ion or 2xAA cell directly. The 32 MHz core provides 8 MIPS for protocol handling while the dedicated AFE (ADC2 with computation, 5-bit DAC, 2 comparators) pairs with a sensor front-end.

Wireless Remote Controls / RF Keyfobs
In remote controls and RF keyfobs the PIC16LF15355T-I/ML's 1.8-3.6 V range and sub-uA sleep current are essential for multi-year coin-cell battery life. The on-chip CWG can drive an IR or sub-GHz transmitter direct from the timing source while the CPU sleeps, reducing BOM cost and current. PWM, comparators and the NCO provide waveform shaping without external logic. The 28-QFN (6x6 mm) fits behind a coin-cell holder in tight industrial form factors, and PPS allows re-routing pins to avoid antenna keepouts.

HVAC and Thermostat Controllers
The PIC16LF15355T-I/ML drives HVAC and thermostat control loops with its 32 MHz MIPS for floating-point-free PIDs, a 10-bit ADC2 with computation for thermistor/conditioning front-ends, and dual I2C/SPI buses for sensor and display modules. -40C to +85C industrial range covers equipment rooms. The 4 PWMs and CWG generate variable-frequency HVAC drive signals on the 28-QFN, and PPS keeps the PCB small. Microchip's MPLAB MCC code-configurator includes thermal-control firmware libraries that target this family.

Low-Power Medical Wearables
In low-power medical wearables the PIC16LF15355T-I/ML combines deterministic interrupt latency, sub-uA sleep current and on-chip analog peripherals in a 28-QFN (6x6 mm) footprint under 10 mm^2. ADC2 with computation off-loads RMS and oversampling math from the CPU, extending battery life on body-worn patches and pulse-oximeter housings. The 5-bit DAC and 2 comparators form a closed-loop Li-Ion charger with MPPT. Industrial -40C to +85C operation supports disposable skin patches during the cold chain.

Consumer White Goods and Appliance Control
Consumer white goods - washing machines, dishwashers, and induction cooktops - use the PIC16LF15355T-I/ML for main-board control because of its 14 KB Flash (enough for sensor-fusion user interface), dual EUSART (HMI display plus inverter link), and the CWG for motor/relay drive. The 28-QFN exposed pad on the underside drops the package junction-to-ambient thermal resistance to low single-digit C/W at moderate drive currents. Industrial -40C to +85C is rated for appliance closets and laundry rooms, and the F suffix variant extends directly to 5V rails.
Được đề xuất
LED Lighting and Driver Controllers
In LED drivers and color-mixing luminaires the PIC16LF15355T-I/ML delivers 4 hardware PWMs and the CWG for flicker-free dimming from 0.1% to 100% duty cycle. The 32 MHz core runs DMX512, DALI or Bluetooth-Mesh stacks via the on-chip EUSART. ADC2 samples ambient or thermal-feedback sensors while the CPU sleeps. The 28-QFN (6x6 mm) drops into compact Zhaga-compatible fixtures, and XLP holds sleep current below 1 uA when a luminaire is in standby mode but still receiving commands over a wired bus.

Ghi chú thiết kế
Estimated: place a 100 nF 0402 ceramic plus a 1 uF 0402/0603 bulk capacitor on each VDD pin, both within 5 mm of the pads. The QFN exposed pad must be soldered to a continuous ground copper pad of at least the package footprint with 0.3 mm-0.4 mm plated thermal vias - this drives thermal resistance down to the package minimum and meets MSL2 floor-life constraints after reflow.
Enable the on-chip Low-Power Regulator (LDO on the LF devices) and set the PMD bits to gate unused peripherals. Sleep current with full RAM retention typically drops below 1 uA when ADC2, CWG and NCO are disabled, per Microchip XLP datasheet figures. For battery-coin designs, choose the LFINTOSC WDT wakeup path so the on-board regulator rail is fully settled at 1.05 V before exiting Sleep.
On this 32 MHz PIC16LF15355T-I/ML design, assign I2C/SPI signals to RC4/RC5 or use Peripheral Pin Select to relocate critical clocks onto the highest-impedance pins. Estimated: bond-wire capacitance on the QFN28 keeps digital-edge slew times above 50 ns for 30 pF loads, so pull-up resistors on I2C lines should stay below 22 kohm on 3.3 V rails to meet the SMBus fast-mode 400 kHz rise-time budget.
Avoid re-routing VPP/MCLR to a regular GPIO function during in-circuit programming with no isolation. The ICSP clock pin (RB6) and ICSP data pin (RB7) need a series resistor to the programmer tool to prevent contention with the application. When migrating code from PIC16F886 to PIC16LF15355, the unused PPS registers default to NULL (high-impedance) - explicitly remap peripherals before first I/O operation.
