PIC16LF1788-E/SS - 28KB Flash 8-bit MCU 32MHz SSOP-28 | Microchip
MPN: PIC16LF1788-E/SS ✓ فعالPIC16LF1788-E/SS جائزہ
A PIC microcontroller (MCU) is a self-contained single-chip computer that integrates a CPU, non-volatile Flash memory, RAM, EEPROM, and a rich set of peripherals such as ADC, op-amps, comparators, PWM, and communication modules. The PIC16 family is a broad 8-bit line of MCUs from Microchip Technology, used across consumer, industrial, and automotive embedded designs. Within that hierarchy, the "LF" prefix denotes low-voltage operation (down to 1.8 V), and "XLP" (eXtreme Low Power) is Microchip's marketing term for ultra-low-power sleep and active current performance, which makes the part especially attractive for battery-powered applications.
Key features of the PIC16LF1788-E/SS include 28 KB Flash, 2 KB SRAM, 256 B EEPROM, internal oscillator, two on-chip operational amplifiers, a bandgap voltage reference, multiple 8/16-bit timers, two CCP modules, two programmable switched-mode controllers, an ADC, comparators, and In-Circuit Serial Programming™ (ICSP™) for in-field firmware updates. The 28-SSOP package is a wide-body 300-mil plastic shrink-small-outline surface-mount package well-suited to hand-soldering and standard reflow profiles.
Typical applications include portable consumer devices, IoT sensor nodes, low-power industrial sensors, battery chargers using the on-chip SMPS controllers, LED lighting controllers, and any embedded design that needs small code footprint, ultra-low-power sleep, and analogue signal conditioning. The "Advanced Analogue" cluster (op-amps + comparators + DAC + programmable SMPS) reduces external analogue IC count in sensor-interface designs.
Designers should plan for a regulated 1.8 V – 3.6 V supply, place the ICSP™ header (PGD/PGC/MCLR) for production programming, and ensure decoupling is per Microchip's PIC16LF1788 datasheet recommendations. As an extended-temperature (-E) part, the device is screened for industrial environments from -40 °C to +125 °C.

عام استعمالات
PIC16LF1788-E/SS کے لیے موزوں ہے 6 ایپلیکیشنs: Battery-Powered IoT Sensor Nodes, LED Lighting Drivers and Dimming Controllers, Low-Power Industrial Sensor Transmitters, Portable Consumer Electronics, Switched-Mode Power Supply (SMPS) Digital Control, Automotive Body and HMI Modules (Non-Safety).
Battery-Powered IoT Sensor Nodes
The PIC16LF1788-E/SS is well matched to battery-powered IoT sensor nodes because its LF core runs from 1.8 V to 3.6 V, allowing direct connection to a single Li-ion or 2x AA alkaline cell. XLP sleep modes drop current to tens of nA between measurements, while the on-chip 2 op-amps and bandgap reference condition thermocouple, RTD, or bridge-sensor signals without external analogue ICs. The 32 MHz CPU provides ample headroom for sensor linearisation and protocol framing. Designers place the MCU between the battery and the sensor front-end, waking on a timer interrupt, sampling, transmitting, and returning to sleep — typically achieving multi-year coin-cell battery life. Note that the -E -40 to +125 °C grade supports outdoor or industrial enclosures.

LED Lighting Drivers and Dimming Controllers
LED lighting designs use the PIC16LF1788-E/SS to combine DMX/0-10 V/DALI input parsing with on-chip PWM and analogue conditioning. The two programmable switched-mode controllers plus two CCP PWM channels drive constant-current LED stages without an external analogue controller. The LF supply range lets the same board accept a 3.3 V regulated rail from an AC-DC front end, simplifying PFC stage isolation. The 28-SSOP footprint reflows cleanly onto standard FR-4 and the -E temperature grade covers enclosed fixture thermals. Designers benefit from the integrated 256 B EEPROM for storing trim and calibration values, and the bandgap reference for accurate current sensing thresholds across thousands of units in production.

Low-Power Industrial Sensor Transmitters
4-20 mA loop-powered and low-power industrial sensor transmitters benefit from the PIC16LF1788-E/SS's LF 1.8 V supply, integrated op-amps, and 12-bit-class ADC for transducer signal conditioning. The on-chip 2 op-amps build instrumentation front-ends for strain-gauge or pressure bridges without a dedicated analogue IC, while the bandgap reference stabilises excitation. The -40 °C to +125 °C industrial temperature grade meets outdoor process-plant environments, and ICSP™ allows field firmware updates and per-unit calibration. The 28-SSOP package suits the small PCBs typical of DIN-rail or in-head transmitters, and the XLP sleep currents allow 4-20 mA loops to operate within the 3.5 mA budget for the MCU.

Portable Consumer Electronics
Portable consumer devices such as wireless remote controls, fitness wearables, electronic thermometers, and personal-care appliances use the PIC16LF1788-E/SS for its LF low-voltage core and XLP sleep performance. The 28 KB Flash supports feature-rich UI logic and BLE/HID command stacks, while 2 KB RAM provides buffer headroom for protocol parsing. The on-chip op-amps and comparators implement touch/proximity sensing and battery-voltage monitoring without external analogue chips. A coin-cell or Li-Po battery powers the device directly thanks to the 1.8 V minimum supply. The 28-SSOP is hand-solder-friendly for prototypes and the -E temperature grade survives enclosed-chassis thermals in wearables or handhelds.

Switched-Mode Power Supply (SMPS) Digital Control
Digitally controlled SMPS designs use the PIC16LF1788-E/SS's two on-chip programmable switched-mode controllers as flexible PWM peripherals, while the 32 MHz CPU runs the regulation loop in firmware. The 2 op-amps sense current and voltage across the inductor and output stage, and the internal bandgap reference provides an accurate error-amplifier reference. The LF supply allows direct operation from a 3.3 V auxiliary winding, eliminating an extra LDO. The 28-SSOP package handles moderate junction temperatures in fan-cooled supplies, and ICSP™ enables in-the-loop firmware tuning. Typical implementations include 50 W DC-DC bricks, PoE powered devices, and isolated auxiliary supplies where one chip replaces a classical analogue PWM controller plus supervisor MCU.

Automotive Body and HMI Modules (Non-Safety)
The PIC16LF1788-E/SS's -E temperature grade of -40 °C to +125 °C covers most automotive body and HMI applications such as interior lighting controllers, mirror adjusters, HVAC blend-door drivers, and seat-control keypads. The integrated op-amps and ADC read potentiometers and current shunts, while the PWM and SMPS controller peripherals drive small motors and LEDs. The LF supply accepts a 3.3 V post-regulator rail from the vehicle's 12 V bus. For safety-critical or AEC-Q100 qualified designs, designers should migrate to a specifically AEC-Q100 listed PIC16 part; the -E grade here is industrial, not automotive-qualified. The 28-SSOP package supports the small PCB form factors typical of in-cabin modules.

ڈیزائن نوٹس
The PIC16LF1788-E/SS is an LF core part and MUST be supplied within 1.8 V to 3.6 V. Operating it from a 5 V rail will damage the part; if the system bus is 5 V, add an LDO (e.g., MCP1700) to derive the 3.3 V MCU rail. Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a bulk 10 µF tantalum or ceramic close to the package. The -E temperature grade (-40 °C to +125 °C) allows industrial enclosures but the LF supply voltage derating must still be respected at high temperature.
Reserving the ICSP™ pins (RB6/PGC, RB7/PGD, MCLR/VPP) is essential for production programming and in-field firmware updates. Do NOT pull MCLR low through a capacitor only; add a 10 kΩ pull-up to VDD and a 100 nF to ground for a proper reset circuit. Avoid using PGC/PGD as outputs driving heavy loads during normal operation, since this can complicate in-circuit debugging. Also remember the LF vs F distinction: a PIC16F1788-E/SS pin-compatible drop-in will NOT start below 2.5 V — verify supply range before migrating.
Estimated: at the maximum 32 MHz CPU speed with all peripherals active, the PIC16LF1788-E/SS draws roughly 6–8 mA from 3.3 V, dissipating approximately 20–26 mW. In the 28-SSOP package with theta_JA ≈ 95 °C/W, the junction temperature rise above ambient is only about 2 °C, leaving substantial thermal headroom for the +125 °C industrial ceiling. For sleep-mode XLP designs, current drops to tens of nA and self-heating is negligible. No external heatsink is required for typical use.
