PIC16LF1764T-I/ST Übersicht
An 8-bit PIC microcontroller (PIC = Peripheral Interface Controller) is a Harvard-architecture RISC MCU built around a small instruction set, on-chip Flash for code storage, integrated peripherals (ADC, PWM, timers, comparators, communications), and GPIO. Within the broader product taxonomy, the PIC16LF1764 belongs to: PIC16F -> 8-bit PIC -> PIC microcontroller -> microcontroller -> semiconductor -> integrated circuit. Its ultra-low-power (XLP) lineage places it alongside other sub-1.8V-capable 8-bit MCUs designed for energy-harvesting and IoT endpoints.
Key features include a 32MHz internal core clock, 12 I/O pins, 10-bit ADC, internal voltage reference, configurable logic cells, and 7KB of self-programmable Flash. The TSSOP-14 footprint suits compact PCBs in sensor-node, wearable, and handheld designs where every square millimeter matters, while the low-voltage 'LF' core extends coin-cell and Li-ion battery life by activating nanoWatt XLP sleep modes.
Architecturally, the PIC16LF1764 uses a 14-bit instruction word with a 49-instruction core, hardware multiplier, and a peripheral pin-select block that remaps digital peripherals to nearly any I/O. Its XLP technology combines multiple idle/sleep modes with active clock gating and selective peripheral shutdown, allowing applications to wake on interrupts while drawing tens of nanoamps.
Typical applications include IoT sensor nodes, battery-powered medical wearables, low-power wireless sensor hubs, energy-harvesting devices, smart-home peripherals, and industrial telemetry. The 10-bit ADC and small package make it well suited to mixed-signal front ends that need modest analog resolution in a tight footprint.
Designers should note that the 'T' suffix denotes tape-and-reel packaging, while the 'I' indicates the industrial -40C to +85C temperature range. Programming is supported by Microchip's MPLAB X IDE and the PICkit or Snap in-circuit debuggers; use the MPLAB Code Configurator (MCC) to generate peripheral drivers and runtime code.

Battery-Powered IoT Sensor Nodes
The PIC16LF1764T-I/ST fits IoT sensor nodes because its 1.8V-3.6V XLP core reaches nanoamp sleep currents, letting coin-cell or Li-ion batteries last years. The 32MHz core handles periodic sensor reads, edge filtering, and BLE/Zigbee transmit preparation while the 10-bit ADC digitizes analog inputs. The 14-pin TSSOP footprint suits 15x20mm sensor PCBs and supports hardware SPI/I2C for external radios. Designers typically run the MCU at 32MHz briefly, then enter sleep until an RTC or interrupt wake. The 7KB Flash accommodates simple protocol stacks (e.g., proprietary sensor or BLE beacon) and over-the-air firmware update stubs.

Wearable Health and Fitness Devices
The PIC16LF1764T-I/ST suits wearable health/fitness designs because its XLP nanoWatt sleep currents extend battery life across heart-rate, step-count, and SpO2 measurement cycles. The 10-bit ADC captures photoplethysmography (PPG) or bio-impedance signals from analog front ends, while the small TSSOP-14 package fits wristbands and patches. The 32MHz core is fast enough for adaptive sampling and on-device filtering. Combined with low-voltage operation, the part runs directly from a single Li-ion or coin cell. Designers should leverage peripheral pin-select to assign PWM, I2C, and ADC flexibly as wearable features evolve.
Empfohlen
Smart Home Wireless Sensors
The PIC16LF1764T-I/ST is well matched to smart-home wireless sensors (door/window, leak, occupancy) thanks to its XLP sleep currents that keep coin cells alive for 5+ years. The 32MHz core wakes the device, reads the sensor, encrypts/transmits the event over an attached radio, then returns to sleep. The 14-pin TSSOP leaves 12 I/O for SPI-attached transceivers, LEDs, and tamper switches. The 1.8V-3.6V supply directly powers CR2032 cells, eliminating boost converters. With 7KB Flash, designers can include Zigbee/LoRa join logic and OTA firmware update hooks without external memory.
Empfohlen
Industrial Sensor Conditioning
The PIC16LF1764T-I/ST serves industrial sensor conditioning where 4-20mA loops or 0-10V analog signals must be digitized, scaled, and reported over RS-485 or CAN. The 10-bit ADC and 32MHz core deliver fast cycle times (sub-millisecond per channel), while the 14-pin TSSOP and -40C to +85C industrial range suit factory-floor enclosures. The 1.8V-3.6V supply accepts a linear regulator from a 24V loop, and the 7KB Flash supports Modbus RTU or CANopen protocol stacks. Designers typically use CLCs and PWMs to generate excitation signals without external op-amps, reducing BOM cost.
Empfohlen
Energy Harvesting Edge Nodes
The PIC16LF1764T-I/ST is ideal for energy-harvesting endpoints (solar, vibration, thermal gradient) because its nanoWatt XLP sleep currents match the harvested energy budget. The 32MHz core wakes briefly to execute sensor reads and transmit, then returns to sleep during ambient charging. The 1.8V-3.6V supply operates directly from supercapacitor or thin-film battery outputs, avoiding boost losses. The 14-pin TSSOP footprint leaves 12 I/O for piezo/voltage harvesting interfaces, ADCs, and a low-power radio. The 7KB Flash fits compact control loops and event scheduling without an external memory IC.
Empfohlen
Low-Power Consumer Remote Controls
The PIC16LF1764T-I/ST fits consumer IR/RF remote controls because its XLP deep sleep at ~20nA lets alkaline AAA cells last the product lifetime. The 32MHz core executes button debouncing, IR carrier generation, or RF packet framing on demand. The 14-pin TSSOP package plus 12 I/O support up to 12 keys plus LEDs, and the 1.8V-3.6V supply runs directly from two AA cells. The 7KB Flash accommodates custom IR protocols (RC5/RC6, Sony SIRC, NEC) or RF stack initialization. The CLC peripherals can replace discrete timing components.
Empfohlen
Portable Measurement Instruments
The PIC16LF1764T-I/ST powers portable hand-held measurement tools (multimeters, moisture meters, light meters) thanks to its 10-bit ADC and 32MHz CPU. The 14-pin TSSOP fits compact probes, and the 1.8V-3.6V supply operates from two AAA cells. The 7KB Flash stores calibration constants and linearization tables, while the 12 I/O drive segmented LCD via charge pumps or scan multiplexers. XLP modes let the device idle between measurements, extending battery life. The device's industrial -40C to +85C rating supports outdoor fieldwork across seasons.

Wichtigste Unterscheidungsmerkmale
- Largest Flash in the PIC16LF1xxx 14-pin TSSOP family (vs. PIC16LF1705T-I/ST)
- Newer XLP sleep architecture for lower quiescent current (vs. PIC16LF1554T-I/ST)
- Enhanced peripheral set (CLC, more PWM, larger RAM) (vs. PIC16LF1615T-I/ST)
Designhinweise
The PIC16LF1764T-I/ST XLP core reaches sub-100nA sleep current when peripherals are disabled and the CPU is gated off. For deep-sleep, configure all unused peripherals to 'off' in the PMD register, disable the ADC, and use a low-power RTCC wake source rather than WDT. At 1.8V supply with 32kHz LF crystal, total quiescent is typically under 1.5uA including leakage. Above 3.3V operation, leakage rises; for coin-cell applications, run as close to 1.8V as the analog front end allows.
Place a 0.1uF ceramic decoupling capacitor within 5mm of the Vdd pin (pin 14) and a 10uF bulk capacitor on the same supply trace. The TSSOP-14 thermal pad is not present, so a 4-layer board with a continuous ground pour is recommended for EMI/RFI immunity. Keep MCLR (pin 1) trace short and provide a 10k pull-up to Vdd for normal operation. If ICSP is used, route PGC/PGD away from switching signals and add 4.7k series resistors near the MCU to reduce programming noise.
Do not drive the MCLR pin directly with a logic output - always use a pull-up resistor or open-drain driver. Do not exceed 3.6V on any I/O pin; the LF core is not 5V tolerant. Configure the PPS (peripheral pin-select) lock carefully: once locked, peripheral remapping requires an unlock sequence. When migrating from PIC16LF1705 firmware, account for the doubled Flash size - vector table and ISR addresses may shift slightly. Verify the LFINTOSC accuracy in your application; factory-trimmed HFINTOSC is +/-2% but LFINTOSC may drift with temperature.
For SPI/I2C peripherals driving external devices, keep traces short and series-terminate clock lines to avoid ringing. The 10-bit ADC sample-and-hold requires the source impedance to be below 10kohm for full accuracy - add an op-amp buffer if the sensor impedance exceeds this. AC coupling is unnecessary for the ADC inputs since the MCU operates single-ended; for differential measurements, use the on-board op-amp peripherals. Avoid routing high-frequency PWM outputs adjacent to ADC analog inputs to prevent digital switching noise from coupling into measurements.
