MPN: PIC16F1765-E/ST ✓ NakahandaPIC16F1765-E/ST Ulas
Key features include a 10-bit A/D converter, operational amplifiers, zero-cross detect, high-current I/Os, programmable ramp generator with slope compensation, peripheral pin select (PPS), and a 10-bit DAC. The 14-pin TSSOP package supports surface-mount designs where PCB real estate is constrained, while the wide operating voltage range from 2.3V to 5.5V allows battery-powered and industrial 5V operation. The -E suffix denotes the extended industrial temperature grade of -40C to +125C.
The PIC16F1765 uses Microchip's enhanced mid-range 8-bit core with a 32MHz internal oscillator option, providing deterministic instruction execution. Intelligent analog integration reduces external component count - the integrated op amps and 10-bit DAC enable closed-loop control without external signal conditioning. The peripheral pin select function remaps digital peripherals to any I/O pin, simplifying PCB layout and BOM optimization.
Typical applications span LED lighting drivers, battery chargers, fan controllers, power-conversion secondary-side control, and sensor conditioning. Designers choose this part when a small-pin-count MCU with strong analog integration is required without the cost or complexity of larger Cortex-M devices.
When designing with this device, verify that the chosen 14-pin TSSOP footprint accommodates the chosen debugger/programmer header. For production programming, reserve the ICSP pins (typically PGD/PGC) or use a bootloader over UART. The TSSOP package has moderate thermal performance and is well-suited to indoor enclosures with low ambient stress.

Tipikal na mga Gamit
PIC16F1765-E/ST ay nararapat para sa 7 aplikasyons: LED Lighting Drivers, Battery Chargers, Fan Speed Controllers, Switch-Mode Power Supply Secondary-Side Control, Sensor Signal Conditioning, Appliance Control Boards, Industrial Sensor Transmitters.
LED Lighting Drivers
The PIC16F1765-E/ST's integrated 10-bit DAC, op amps, programmable ramp generator, and zero-cross detect make it well suited for constant-current LED driver control. The 10-bit DAC generates dimming setpoints, while the integrated op amp closes the current-sense loop without external conditioning.

Battery Chargers
The PIC16F1765-E/ST fits secondary-side battery-charger control with its integrated 10-bit ADC for voltage/current sensing and 10-bit DAC for charge-voltage reference. The 2.3V to 5.5V input range covers single-cell Li-Ion and multi-cell NiMH chemistries with appropriate external pass elements. The enhanced mid-range core supports CC/CV state-machine logic, and the TSSOP-14 footprint enables compact charger modules. Designers can leverage the on-chip op amps for current-sense amplification, reducing external component count.

Fan Speed Controllers
For brushless DC and AC fan speed controllers, the PIC16F1765-E/ST's zero-cross detect and programmable ramp generator enable smooth phase-angle or PWM control. The 10-bit ADC reads tachometer feedback, while the integrated op amps condition sensor signals without external ICs. The TSSOP-14 footprint suits small inline fan-control modules, and the extended -40C to +125C temperature grade covers thermally enclosed fan-hub environments. Total BOM cost benefits from the high level of analog integration.

Switch-Mode Power Supply Secondary-Side Control
The PIC16F1765-E/ST handles secondary-side regulation in isolated SMPS designs via its integrated 10-bit ADC for output voltage sensing and the 10-bit DAC for opto-isolator emulation or direct feedback. The peripheral pin select allows flexible remapping of PWM and timer outputs to compensate for optocoupler interface pins. The TSSOP-14 package fits secondary-side PCB real-estate constraints inside 1W to 50W adapter form factors, and the extended temperature grade handles adapter thermal-rise conditions.

Sensor Signal Conditioning
The PIC16F1765-E/ST's integrated op amps, 10-bit ADC, and 10-bit DAC create a complete sensor signal-chain in a single chip. The op amps provide gain and filtering for low-level sensor outputs, the ADC digitizes the conditioned signal, and the DAC can generate excitation or reference voltages. The TSSOP-14 footprint suits compact sensor modules for industrial process control, HVAC, and environmental monitoring where PCB area is constrained and analog integration reduces BOM cost.

Talaan ng Disenyo
The PIC16F1765-E/ST operates from 2.3V to 5.5V. Place a 100nF decoupling capacitor as close as possible to the VDD pin (pin 14), with a 10uF bulk capacitor on the supply rail. For battery-powered designs, account for the device's active and sleep current; the integrated op amps and DAC can draw additional bias current that should be considered when estimating total quiescent consumption.
At maximum system clock of 32MHz and 5V supply, the TSSOP-14 package has moderate thermal performance. For continuous high-duty-cycle operation at elevated ambient temperatures, calculate junction temperature using the package's theta_JA value (refer to manufacturer datasheet thermal data). The extended -40C to +125C temperature grade covers most industrial environments without additional heatsinking.
Do not leave the MCLR pin floating - tie it to VDD through a 10kohm pull-up resistor for normal operation, or directly to VDD if unused. Configure unused I/O pins as outputs and tie them to ground to minimize current consumption. When using the ICSP programmer, ensure that the PGD/PGC pins are not loaded with heavy external capacitance that interferes with programming signals.
Route analog signals (ANx, DAC, op-amp inputs/outputs) away from high-frequency digital traces to minimize coupling. Use a ground plane under the TSSOP-14 footprint, with separate analog and digital ground regions joined at a single point near the VSS pin. Place the decoupling capacitor on the VDD pin with the shortest possible trace length to minimize supply noise.
When using the integrated op amps for high-impedance sensor inputs, add guard traces or shields to reduce leakage and noise pickup. The 10-bit ADC and DAC are adequate for most sensor-conditioning applications but have limited resolution for precision measurement - apply input averaging and digital filtering in firmware to maximize effective resolution beyond the nominal 10-bit LSB step.
