PIC16F1788-I/ML - 32MHz 8-Bit MCU 28KB Flash 28-QFN | Microchip
MPN: PIC16F1788-I/ML ✓ فعالPIC16F1788-I/ML جائزہ
An 8-bit microcontroller (MCU) is a single-chip computer that integrates an 8-bit CPU core, program memory (Flash), data memory (SRAM), non-volatile storage (EEPROM), and a set of on-chip peripherals (timers, ADC, communication ports, GPIO) into one package. Within the broader hierarchy, the PIC16F1788 sits inside the PIC16F1xxx family -> PIC16 family -> 8-bit PIC microcontrollers -> microcontrollers -> microcontrollers & processors -> semiconductors. It is built on a low-power CMOS RISC architecture with a 200 ns instruction execution time (5 MIPS at 32 MHz), and features Microchip's XLP™ (eXtreme Low Power) technology for battery-friendly designs.
Key features include an integrated 12-bit ADC, two 8-bit DACs, two comparators, a 16-bit PWM module and enhanced USART, I²C and SPI interfaces. The 28-QFN package exposes 25 general-purpose I/O pins and a Master Synchronous Serial Port (MSSP) for peripheral expansion. The on-chip Core Independent Peripherals (CIPs) such as the Complementary Waveform Generator (CWG) and Numerically Controlled Oscillator (NCO) enable hardware-driven control loops without CPU intervention.
Typical applications include industrial sensor conditioning, LED lighting control, motor control, low-power IoT sensor nodes, battery chargers and small-form-factor consumer electronics. The combination of two DACs, a 12-bit ADC and XLP sleep currents in the nanoampere range also makes the part a strong candidate for portable instrumentation.
When designing with this part, remember that the 28-QFN exposed pad is the chip's primary thermal path and must be soldered to a sufficient copper pour to meet the rated junction-to-ambient thermal resistance. All unused I/O pins should be configured as outputs low to minimise sleep current.

عام استعمالات
PIC16F1788-I/ML کے لیے موزوں ہے 6 ایپلیکیشنs: Industrial Sensor Conditioning, LED Lighting Control, Small Motor Control (Brushed DC / Stepper), Battery-Powered IoT Sensor Node, Portable Medical & Wellness Devices, Small Consumer Electronics (Toys / Appliance UI).
Industrial Sensor Conditioning
The PIC16F1788-I/ML fits industrial sensor conditioning because of its 12-bit ADC (up to 11 channels) and two 8-bit DACs. The 5 MIPS throughput at 32 MHz supports real-time linearisation and digital filtering on bridge, RTD and 4-20 mA sensor inputs. Two on-chip comparators enable hardware threshold detection without CPU load. The 2.3-5.5 V supply range is friendly with both 3.3 V and 5 V industrial backplanes, and XLP sleep currents in the nanoampere range allow always-on installations. Industrial -40 °C to +85 °C operating range covers plant-floor environments. Source: Microchip datasheet 40001814.

LED Lighting Control
PIC16F1788-I/ML is a strong fit for LED lighting drivers thanks to its 16-bit enhanced PWM, Complementary Waveform Generator (CWG) and two 8-bit DACs for analog dimming reference. The CWG can synthesize dead-band-controlled complementary PWM pairs to drive a half-bridge LED MOSFET stage with no CPU overhead. Nanoamp-level sleep currents allow the part to remain in standby until a control signal arrives, which is critical for battery-powered luminaires. The 25 GPIO and 28-QFN footprint keep the BOM small enough for MR16 retrofit lamps. Source: Microchip datasheet 40001814.

Small Motor Control (Brushed DC / Stepper)
PIC16F1788-I/ML fits small brushed DC and stepper motor control because it combines a 16-bit enhanced PWM, two comparators for current sensing and the CWG for hardware commutation. The 5 MIPS throughput at 32 MHz is sufficient for PI torque loops up to several kHz, and the 12-bit ADC simultaneously samples back-EMF for sensorless stepper positioning. Nanoamp XLP sleep modes let battery-powered actuators idle for years. The 28-QFN exposed pad provides the thermal headroom needed for continuous MOSFET drive without an external heatsink.

Battery-Powered IoT Sensor Node
PIC16F1788-I/ML suits battery-powered IoT sensor nodes thanks to its XLP™ sleep currents in the nanoampere range and integrated 12-bit ADC. The 2.3-5.5 V supply range accepts a single Li-ion cell or two AAs, and the EUSART/MSSP peripherals support UART, SPI and I²C sensors. The 2 KB SRAM and 28 KB Flash are sufficient for Microchip's MLA or LoRa/BLE stack on small frames. The Core Independent Peripherals (CIPs) wake the CPU only on threshold-crossing events, extending coin-cell life into multi-year territory.

Portable Medical & Wellness Devices
The PIC16F1788-I/ML fits portable medical and wellness devices because it offers a low-noise 12-bit ADC for accurate biosignal acquisition, two 8-bit DACs for stimulation-waveform generation and XLP nanoamp sleep currents. With the industrial -40 °C to +85 °C range it operates reliably on a wrist or in a handheld housing, and the 28-QFN 6 × 6 mm footprint saves PCB area in slim form factors. Microchip's MPLAB XC8 toolchain and validated firmware libraries shorten IEC 62304 development cycles for medical firmware.

Small Consumer Electronics (Toys / Appliance UI)
PIC16F1788-I/ML is a strong fit for small consumer products such as appliance user interfaces and battery toys because it provides 25 GPIO for keypad, LED and buzzer control, plus PWM-driven motor or backlight control. The two comparators enable touch-button or rotary-encoder decoding without external logic. The 2.3-5.5 V supply is friendly with 2-3 AA cells or a single Li-ion cell. The 28-QFN 6 × 6 mm package keeps the BOM compact, and the industrial temperature grade covers kitchen and outdoor appliances. Source: Microchip datasheet 40001814.

ڈیزائن نوٹس
The 28-QFN exposed pad is the primary thermal path for PIC16F1788-I/ML. Solder the e-pad to a copper pour of at least 25 mm² and add 4-6 thermal vias to the inner/ground plane to stay within the datasheet junction-to-ambient thermal resistance. Without a proper e-pad solder joint, the silicon can overheat during sustained PWM-driven peripheral activity. Estimated: assume a 0.5 W dissipation and verify against the datasheet theta_JA figure if available.
Decouple VDD with a 100 nF X7R ceramic placed within 3 mm of the package, plus a 10 µF bulk capacitor on the board. Add a ferrite bead or inductor if a switching converter shares the supply. Configure unused I/O as outputs low or inputs with the internal weak pull-up enabled to minimise XLP sleep current. Estimated: with this layout the XLP sleep current stays in the nanoampere range defined in the datasheet.
Do not skip configuring the PPS (Peripheral Pin Select) registers when moving from PIC16F1787-I/ML or PIC16F1786-I/ML firmware - although all three are pin-compatible, the default peripheral mappings can differ and a blank PPS configuration can leave MSSP, EUSART or PWM on the wrong pins. Always reinitialise the PPS in your port setup routine and verify with a logic analyser on first prototype bring-up.
Route the ICSP lines (PGC/PGD) as a short, parallel pair away from PWM or switching traces to avoid programmer/debugger noise. Place a 4.7 kΩ pull-up on MCLR for robust in-circuit serial programming. Keep the analog reference pins (Vref+/Vref-) away from PWM edges and add a 10 nF + 100 nF capacitor pair on each to reduce ADC noise.
