PIC16LF1764-E/ML - 8-bit MCU, 7KB Flash, 32MHz, 16-QFN | Microchip
MPN: PIC16LF1764-E/ML ✓ פעילPIC16LF1764-E/ML סקירה
An 8-bit microcontroller (MCU) is a programmable processor with an 8-bit data bus that integrates CPU core, non-volatile program memory (Flash), volatile working memory (RAM), and a configurable set of peripheral blocks on a single die. MCUs occupy the bottom of the embedded computing hierarchy below microprocessors and SoCs, and PIC microcontrollers specifically use a Harvard RISC architecture with separate program and data buses, deterministic instruction timing, and ultra-low-power sleep modes targeted at battery and energy-harvesting designs.
Key features include 7 KB self-programmable Flash, 512 bytes SRAM, 128 bytes EEPROM, a 10-bit A/D converter with multiple channels, op-amp peripherals, zero-cross detect, high-current I/O pins, and XLP technology with nanoWatt sleep currents below 100 nA typical. The PIC16LF1764 supports up to 14 I/O pins depending on package variant, plus peripheral touch sensing, PWM, and configurable logic cells that allow on-chip signal conditioning without external components.
Architecturally the device uses Microchip's enhanced mid-range 8-bit core with 49 instruction types, a 14-bit instruction word, and hardware multiplier assist. The integrated peripherals are accessed via a peripheral pin select (PPS) crossbar in larger variants, while signal-chain functions such as op amps, comparators, and DAC references are tied directly to specific I/O pins, giving engineers a small footprint yet capable analog-front-end platform.
Typical applications include IoT sensor nodes, low-power wireless remote controls, LED lighting controllers, energy-harvesting switches, small motor/valve drivers, and battery-powered medical or wearable devices. The 4x4 mm QFN package also makes it suitable for space-constrained consumer and industrial modules. The -E/ML extended temperature grade enables automotive under-hood and outdoor industrial deployments as long as AEC-Q100 qualification is not mandatory.
Designers should note the 1.8V-3.6V supply window is narrower than the F-variant's 2.3V-5.5V range, so the LF part is the correct choice for single alkaline (1.5V) and coin-cell supplies. Take care with the exposed pad - it must be soldered to the PCB ground plane for thermal and electrical performance. Programming is supported via ICSP (In-Circuit Serial Programming) with no high-voltage Vpp required on the LF device.

IoT Wireless Sensor Node
The PIC16LF1764-E/ML's 7 KB Flash and 512 B RAM comfortably host state-machine code for BLE/Zigbee sub-gig co-processor front-ends, while its 1.8 V-3.6 V supply window matches single-cell coin-cell lithium power rails. The 10-bit ADC with multiple channels digitizes temperature, humidity, and battery voltage, and the integrated op-amps condition thermistor / photodiode signals directly without external instrumentation amplifiers. nanoWatt XLP sleep currents below 100 nA typical enable multi-year battery life on coin cells, a key advantage for door/window contact sensors, environmental monitors, and asset tracking tags where the MCU wakes briefly to sample and transmit, then returns to sleep. The 4x4 mm QFN footprint keeps the BOM compact for miniature sensor modules.

LED Lighting Controller
Zero-cross detect and high-current I/O on the PIC16LF1764-E/ML let the device drive TRIAC / MOSFET dimming stages directly from the AC mains sense path without extra components. The integrated op-amps close the loop on constant-current LED regulation, while the 10-bit ADC samples light sensor feedback for daylight harvesting. The -40 C to +125 C extended industrial temperature grade supports outdoor fixture electronics and under-cabinet luminaires. Wide 1.8 V-3.6 V operation lets the MCU run from a small auxiliary supply derived after the main AC-DC stage. The 7 KB Flash hosts DMX-512, 0-10 V, and DALI basic frame handling, while 512 B RAM is adequate for smooth fade transitions.

Battery-Powered Remote Control
Handheld remote-control designs benefit from the PIC16LF1764-E/ML's nanoWatt XLP technology, which keeps quiescent current under 100 nA typical in sleep so two AAA cells can last the product's lifetime. The 32 MHz core executes IR protocol encoding (RC5, NEC, proprietary) with deterministic timing, and the 10-bit ADC reads joystick or button-array potentiometers for proportional control. The integrated op-amps buffer microphone inputs for voice-command variants without extra op-amp ICs. The 16-QFN (4x4 mm) package fits behind a button matrix in slim industrial remote enclosures. The wide 1.8 V-3.6 V supply window tolerates battery droop from alkaline cells near end-of-life.

Energy-Harvesting Switch / Sensor
Energy-harvesting wireless light switches and condition sensors rely on the PIC16LF1764-E/ML's nanoWatt modes to wake only on GPIO edge events, sample, transmit, and return to sleep within microjoules of harvested energy. The 10-bit ADC measures piezoelectric or photovoltaic harvester voltages, while the integrated op-amps condition sensor signals. The 1.8 V minimum operating voltage lets the MCU boot from a depleted supercapacitor / thin-film battery pack on first power-up, an advantage over F-process 2.3 V minimum parts. The 4x4 mm QFN package is small enough to fit inside a wall-switch back-box module behind the rocker mechanism.

The PIC16LF1764-E/ML's high-current I/O pins source / sink enough current to drive small DC motor H-bridges or solenoid valves directly through external FETs, while the integrated op-amps close the loop on back-EMF sensing and current monitoring. The 10-bit ADC samples motor current and position sensors, and the PWM peripheral generates brushed DC or stepper drive waveforms. The -40 C to +125 C extended industrial temperature grade supports under-hood and outdoor valve applications. The 7 KB Flash hosts PI/PID control loops and fault-handling routines that protect pumps and actuators from stall conditions.

Industrial Sensor Transmitter
Industrial 4-20 mA loop-powered sensor transmitters benefit from the PIC16LF1764-E/ML's low minimum operating voltage (1.8 V), which lets the MCU start from a minimal shunt regulator at the low end of the 4-20 mA compliance range. The integrated op-amps amplify bridge / thermocouple / RTD sensor signals directly, and the 10-bit ADC digitizes process variables for HART or wireless-HART modems. The -40 C to +125 C extended industrial temperature grade covers outdoor process-plant cabinets and oil-field installations. The 7 KB Flash hosts linearization tables and diagnostic routines required by IEC 61508 SIL-rated transmitter designs.

הערות תכנון
The PIC16LF1764-E/ML's nanoWatt XLP modes drop quiescent current to < 100 nA typical in sleep. For battery-life estimation, model the wake/sample/transmit/sleep profile and verify with Microchip's MPLAB X Energy Probe. Bulk decoupling on VDD should be a 100 nF ceramic close to the pin and a 10 uF tantalum / ceramic at the PCB supply entry; for sleep-mode robustness add 100 nF directly at AVDD when the ADC is used.
The 16-QFN exposed pad must be soldered to a contiguous PCB ground plane with thermal vias to sink die heat and ensure electrical grounding. QFN-16 thermal resistance theta-JA is approximately 40 C/W on a 2-layer 1 oz board - verify with the Microchip package thermal model for high-temperature applications. Leave the EP clear of signal traces so the ground pour is uninterrupted, and provide at least 4 thermal vias under the EP for proper heat dissipation.
Place the 32.768 kHz crystal (if used) and its load capacitors within 5 mm of the OSC pins and guard the traces with a ground ring to minimize stray capacitance. Route ICSPDAT and ICSPCLK together to the programming header with no crossovers, and ensure MCLR has a 10 kohm pull-up to VDD and a 100 nF decoupling cap to ground for in-circuit programming reliability. Keep ADC analog traces short and away from PWM switching lines.
Do not assume LF and F variants have identical electrical characteristics - the LF minimum voltage is 1.8 V vs the F 2.3 V, so a 1.8 V brownout circuit on a 1764 design will not protect an F variant. Always check the Configuration Word settings (WDTE, LVP, etc.) before lock-out, because low-voltage programming (LVP) bit conflicts can prevent high-voltage programmers from re-flashing a locked part.
