PIC16LF1764-E/ST - 8-Bit 32MHz 7KB Flash MCU | Microchip
MPN: PIC16LF1764-E/ST ✓ Hoạt độngPIC16LF1764-E/ST Tóm tắt
An 8-bit microcontroller (MCU) is a small computing system on a single integrated circuit that combines an 8-bit CPU core, program memory (Flash/ROM), data memory (RAM), and a configurable set of digital and analog peripherals. The 8-bit MCU category sits within the broader taxonomy of microcontrollers, which themselves belong to embedded processors and semiconductors. PIC® XLP™ (eXtreme Low Power) is Microchip's ultra-low-power 8-bit architecture targeting battery-operated and energy-harvesting applications.
Key features include eXtreme Low Power (XLP) technology with active current typically below 50 µA/MHz, a 10-bit Analog-to-Digital Converter (ADC), Configurable Logic Cells (CLC), Complementary Waveform Generators (CWG), and multiple communication peripherals including I²C, SPI, and Enhanced USART. The TSSOP-14 package measures approximately 4.40 mm × 5.00 mm with 0.65 mm pitch, making it suitable for compact PCB layouts while preserving easy hand-soldering during prototyping.
The PIC16LF1764 uses Microchip's enhanced mid-range core with a 14-bit instruction word and a 2-stage pipeline, delivering deterministic interrupt response for real-time control tasks. The integrated op-amps and 10-bit ADC enable direct sensor signal conditioning on-chip, reducing external component count in sensor-interface designs.
Typical applications include IoT sensor nodes, low-power wireless transmitters, battery-powered handheld instruments, LED lighting controllers, home-automation peripherals, and small motor-control loops. Its XLP characteristics also suit remote controls and energy-harvesting switch interfaces.
When designing with this part, allocate the RA0–RA5/RC0–RC7 pins carefully to balance analog and digital functions; consult the device pinout table in the manufacturer datasheet before locking the PCB. Ensure the configuration-word settings (oscillator, watchdog, code protection, brown-out) are set in code prior to first programming to avoid locked-out parts.

Ứng dụng tiêu biểu
PIC16LF1764-E/ST phù hợp cho 7 Áp dụngs: Battery-Powered IoT Sensor Nodes, LED Lighting Controllers, Home Automation Peripherals, Low-Power Wireless Transmitters, Small Motor-Control Loops, Portable Medical and Wellness Devices, Industrial Sensor Transmitters.
Battery-Powered IoT Sensor Nodes
The PIC16LF1764-E/ST suits IoT sensor nodes because its XLP™ technology keeps active current below 50 µA/MHz and sleep current in the nanoamp range. Operating from 1.8 V to 3.6 V, it accepts single-cell Li-ion, two-AA, or coin-cell batteries without a boost converter. The integrated 10-bit ADC and on-chip op-amps allow direct conditioning of analog sensors such as thermistors, photodiodes, or wheatstone bridges, while the I²C/SPI/EUSART peripherals connect to radios like LoRa or BLE modules. Total system BOM shrinks to one MCU, one sensor, one decoupling cap, and a battery holder.

LED Lighting Controllers
The PIC16LF1764-E/ST drives constant-current LED strings using its 10-bit PWM, Configurable Logic Cells (CLC), and Complementary Waveform Generator (CWG) peripherals. Multiple PWM channels permit RGB or warm-white + cool-white mixing while keeping firmware loop overhead low at 32 MHz. The 1.8 V–3.6 V operating rail matches small buck-driver supplies, and the on-chip op-amp closes the LED-current feedback loop without external analog ICs. Designers can implement smooth fades and temperature-derating algorithms within the 7 KB Flash budget.

Home Automation Peripherals
For wall switches, occupancy sensors, and HVAC zone controllers, the PIC16LF1764-E/ST provides enough Flash (7 KB) for wireless stacks like Zigbee or Bluetooth Low Energy via SPI-attached modules. The 14-TSSOP footprint drops easily behind a standard wall-box faceplate, and the extended -40 °C to +125 °C operating range covers unheated attic spaces. Zero-cross detect on-chip enables silent AC-triac control for dimmer modules, eliminating the need for external opto-isolated zero-cross circuitry.
Được đề xuất
Low-Power Wireless Transmitters
The PIC16LF1764-E/ST acts as a low-power host controller for sub-GHz or 2.4 GHz transmitter modules in remote-control and telemetry applications. Its EUSART bit-bangs simple protocols, while SPI directly drives modules such as the CC1101 or nRF24L01. XLP sleep mode drops quiescent current below 100 nA, enabling multi-year battery life in door sensors or asset trackers. The 32 MHz core executes sensor-read-and-transmit cycles in microseconds, so the MCU spends the vast majority of its time asleep.
Được đề xuất
Small Motor-Control Loops
Closed-loop DC-fan, pump, or micro-servo control fits within the PIC16LF1764-E/ST's capability set. The CWG peripheral generates complementary PWM with dead-band control, while the on-chip op-amp conditions back-EMF or current-sense feedback. 32 MIPS of core throughput updates PID loops at multi-kilohertz rates, well above the bandwidth needed for thermal-control fans or solenoid drivers. The TSSOP-14 package places the entire controller inside small BLDC modules previously requiring a multi-chip analog solution.

Portable Medical and Wellness Devices
Battery-operated wellness devices such as pulse oximeters, blood-pressure cuffs, and digital thermometers benefit from the PIC16LF1764-E/ST's combination of a 10-bit ADC, on-chip op-amps, and XLP™ low-power operation. The MCU can directly amplify a photodiode or thermistor bridge, eliminating an external instrumentation amplifier and reducing the analog front-end to a handful of passives. The 1.8 V–3.6 V operating range works with two alkaline or one coin-cell battery, while the extended -40 °C to +125 °C range supports sterilization and outdoor use cases.

Industrial Sensor Transmitters
In 4–20 mA loop-powered or wirelessHART sensor transmitters, the PIC16LF1764-E/ST delivers deterministic 8-bit performance with the extended -40 °C to +125 °C industrial temperature range. Its CLC peripheral implements custom digital filters for noise rejection on slow analog signals such as strain-gauge or RTD inputs. With SPI/I²C buses, the MCU can drive external DACs (e.g., MCP4921) or ADCs (e.g., MCP3421) when higher resolution is needed. The TSSOP-14 package simplifies conformal-coated board layouts common in process-control instruments.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor within 3 mm of the VDD pin (pin 5) and a 10 µF bulk capacitor near the supply input. For battery-operated designs, exploit the PIC16LF1764-E/ST's XLP sleep modes (Sleep, Doze, and Idle) to drop quiescent current to sub-1 µA. Disable unused peripherals via the PMD (Peripheral Module Disable) registers before entering Sleep to minimize leakage; each enabled-but-idle peripheral draws microamps of bias current that materially shortens battery life in coin-cell applications.
Keep analog traces (AN0–AN10) short and routed away from the PWM output traces and digital switching nodes. Use a single-point ground tie beneath the package VSS pin, and avoid daisy-chaining analog and digital grounds through the MCU. The 14-pin TSSOP land pattern with 0.65 mm pitch is tolerant of hand-soldering when using a chisel-tip iron and 0.4 mm lead-free solder, but production runs should use no-clean paste and a reflow profile with a peak of 245 °C for 30 seconds.
Do not leave the MCLR/VPP pin floating — always tie it to VDD through a 10 kΩ resistor, optionally with a 100 nF cap to ground for noise filtering. Configuration bits (oscillator, watchdog, brown-out reset, code protection) must be set inside the firmware's CONFIG pragma/asm directive before programming; an unprogrammed CONFIG register can leave the part in an unbootable state. When migrating from PIC16F1764 to PIC16LF1764, verify that any peripheral operating above 3.6 V on the F variant is re-clocked or rescaled; the LF variant's lower VDDmax may otherwise produce unreliable ADC readings near the top of the input range.
Thông tin tuân thủ
RoHS and lead-free compliance confirmed by Microchip product family datasheet 40001827. AEC-Q100 is not applicable to consumer-grade 8-bit PIC MCUs; automotive designers should reference the PIC16F1764-E/ST VAO variants.
