PIC16F753-I/ST Übersicht
A PIC microcontroller (Programmable Interrupt Controller) is a class of 8-bit RISC microcontrollers built around a Harvard architecture with separate program and data buses, enabling single-cycle instruction execution. The PIC16F family sits in Microchip's mid-range lineup and is widely adopted in consumer appliances, motor control, lighting, and battery-powered sensor nodes because of its deterministic interrupt latency, ultra-low power sleep modes, and rich set of on-chip analog peripherals that reduce BOM cost. Hypernyms for this category include: microcontroller -> MCU -> embedded processor -> semiconductor -> integrated circuit.
Key features of the PIC16F753-I/ST include a 9-bit DAC with selectable reference, a programmable switch-mode controller companion (on related PIC16HV753 variants), 2 op-amps/ comparators, 4-channel 10-bit ADC, and nanoWatt Technology power management for sleep currents below 100 nA. The device operates across 2.0V to 5.5V supply rails and supports in-circuit serial programming (ICSP) via two pins, allowing firmware updates without removing the part from the board.
Architecturally, the PIC16F753 uses a 14-bit instruction word RISC core with 8-level hardware stack, addressable 4K program space, and a 256-byte data EEPROM. On-chip peripherals are accessed through a unified SFR bus, and the 9-bit rail-to-rail DAC utilizes a resistor-string architecture trimmed at the factory for monotonic operation. The on-chip 8 MHz HF oscillator is factory calibrated to ±1% across voltage and temperature, eliminating the need for an external crystal in many closed-loop control systems.
Typical applications for PIC16F753-I/ST include LED driver controllers, small appliance controls, battery chargers, fan speed regulators, and sensor signal conditioning. Its analog-rich peripheral set makes it a strong fit for cost-down conversions of designs currently using a baseline MCU plus a discrete DAC or op-amp combination.
When designing with this part, designers should leave PB.6 and PB.7 as ICSP clock/data pins or include test pads for in-circuit programming access. Layout should keep the VDD decoupling capacitor within 5 mm of the supply pin and route the analog AVREF traces away from PWM edges to minimize digital-to-analog coupling on the DAC output.

Typische Anwendungen
PIC16F753-I/ST ist geeignet für 7 Anwendungs: LED Color-Mixing and Dimming Controller, Battery-Powered Sensor Signal Conditioning, Small Appliance Control Board, Brushed DC Motor Speed Regulator, Automotive Lighting and Accessory Module, Battery Charger Termination Controller, Industrial Panel-Meter and Indicator Module.
LED Color-Mixing and Dimming Controller
The PIC16F753-I/ST drives multi-channel LED strings through its 10-bit ECCP PWM and a 9-bit rail-to-rail DAC, both of which are essential for color-temperature blending and constant-current dimming. Designers use the DAC as a programmable reference for the LED current-sense amplifier, while the ECCP deliver phase-correct PWM dimming at up to 20 kHz to avoid audible flicker. The integrated 8 MHz HFINTOSC is factory-calibrated to ±1%, keeping PWM frequency stable across thermal drift in enclosed luminaires. With 3.5 KB of Flash and 128 bytes of RAM, the part runs closed-loop color-temperature compensation with comfort-daylight mode, including serial DMX or 0-10 V input decoding - all in a compact TSSOP-14 footprint that fits inside GU10 and MR16 bulb housings.

Battery-Powered Sensor Signal Conditioning
Tight power budgets make the PIC16F753-I/ST ideal for wireless sensor nodes: nanoWatt Technology holds standby current below 100 nA at 2 V, and the 8 MHz internal oscillator eliminates the external crystal that would otherwise drain current when active. Sensor conditioning chains use the on-chip comparators with selectable references as window discriminators, and the 9-bit DAC generates calibrated excitation bias for resistive bridges (load cells, thermistors). The 4-channel 10-bit ADC samples at up to 50 ksps with the internal RC osc as the clock source. ICSP over RB6/RB7 lets OEM firmware be re-flashed on finished boards without uninstalling the module.
Empfohlen
Small Appliance Control Board
Coffee machines, slow cookers, induction stoves and small kitchen appliances require a single-IC control platform that combines an MCU with analog set-points, zero-crossing triac firing, and a rotary-encoder user interface. The PIC16F753-I/ST serves exactly that role: the ECCP drives the triac pulse train, the 9-bit DAC provides a programmable reference for temperature probe calibration, and the comparator measures zero-crossings directly through an isolated resistor divider. TSSOP-14 plus 2.0 V min supply lets the same hardware run directly from a low-cost non-isolated DC after the rectifier. With 3.5 KB of Flash, the firmware easily fits state-machine code for safety, beeper patterns, and EEPROM-stored user preferences.
Empfohlen
Brushed DC Motor Speed Regulator
The PIC16F753-I/ST performs closed-loop brushed DC motor control using the 10-bit ECCP with complementary outputs, plus the comparator block to measure back-EMF for sensorless speed feedback at low cost. The 9-bit DAC sets the soft-start acceleration profile through an external op-amp summing network, allowing deterministic ramp curves without fixed resistors. With 5 MIPS throughput at 20 MHz the inner loop runs at 40 µs per cycle, more than adequate for low-RPM appliance fans and small pumps. The TSSOP-14 footprint lets the controller fit alongside the H-bridge MOSFETs on a single-sided PCB. Cycle-by-cycle current limit using the on-chip comparator protects the FETs against stall events.

Automotive Lighting and Accessory Module
Although not AEC-Q100 qualified itself, the PIC16F753-I/ST is widely used in non-safety automotive accessories such as ambient lighting, RGB underbody kits, and trailer controllers running from the 12 V vehicle battery. A simple pre-regulator drops the supply to 5 V, where the device runs on the full 2.0 V to 5.5 V range. The 9-bit DAC drives the LED hue channel while the ECCP delivers smooth PWM fade-in / fade-out animations. Inductive loads (relays, solenoids) are switched through external FETs driven by GPIO with optional hardware dead-band control. Designers should keep RB6 and RB7 accessible for factory programming through the OBD-II port or vendor diagnostic pads.
Empfohlen
Battery Charger Termination Controller
The PIC16F753-I/ST performs voltage-and-temperature terminated charging for 1-4 cell Li-ion and NiMH packs by continuously sampling the cell voltage with the 4-channel 10-bit ADC and switching the charge path through the ECCP output. The 9-bit rail-to-rail DAC generates the precise reference voltage for the comparator-based cell-voltage window discriminator. The internal 8 MHz oscillator removes the need for a costly external crystal - a major BoM saving for low-cost consumer charger designs. 128 bytes of SRAM cover the small state machine required for charge phases (precondition, fast-charge, top-off, termination, trickle). This TSSOP-14 footprint fits inside the charger housing without a daughter board.
Empfohlen
Industrial Panel-Meter and Indicator Module
Process-control panel meters and stack-light indicators run reliably on the PIC16F753-I/ST thanks to the on-chip analog peripherals. The 9-bit DAC is repurposed as a 4-20 mA loop reference, while the 10-bit ADC digitizes thermocouple or process inputs. Industrial 24 V systems work through a simple resistor pre-regulator dropping to 5 V, where the device runs cleanly. Watchdog timer, brown-out reset at 2.0 V, and high ESD-tolerant GPIO on all pins give the panel-meter module reasonable robustness in factory environments. ICSP on RB6/RB7 enables local re-flash via service-accessible programming pads, simplifying field updates of indicator firmware.

Wichtigste Unterscheidungsmerkmale
- Integrated 9-bit rail-to-rail DAC with selectable reference (vs. PIC16F1703-I/ST)
- Same TSSOP-14 footprint across the PIC16F753 family for layout reuse (vs. PIC16F716-I/ST)
- Extended-temperature grade option in identical package (vs. PIC16F753-I/SL)
Designhinweise
Estimated: at 20 MHz CPU speed the PIC16F753 generates harmonic content up to about 200 MHz from internal clock tree edges. Place a 100 nF X7R decoupling capacitor within 5 mm of the VDD pin and a 10 µF bulk capacitor close to the IC for clean analog reference performance. Keep AVREF traces routed short and parallel to a ground return.
RB6 (ICSPCLK) and RB7 (ICSPDAT) MUST not be held low by external circuitry during reset or programming. Many boards accidentally wire these pins to 4.7 k pull-down resistors for safety, which then prevents ICSP access. Use 10 k pull-ups instead, or provide isolation diodes if the pin must sink key current.
Estimated: the TSSOP-14 package has theta_JA of approximately 90 C/W on a 2-layer 1 oz copper FR-4 board with minimal copper pour. At +85 C ambient the junction rises about 9 C above ambient at any power dissipation below 100 mW. Since the device dissipates well under 50 mW in typical 5 V / 5 MIPS operation, no special thermal relief is needed.
The PIC16F753 includes a Brown-out Reset (BOR) module selectable from 2.0 V to 4.2 V thresholds. Always enable BOR for line-powered applications to protect EEPROM during undervoltage events. For pure battery designs, set BOR to the lowest threshold (2.0 V) to extract maximum energy from depleted cells.
Compliance-Informationen
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - PIC16F753 is targeted at industrial/consumer markets; for automotive safety applications use PIC16F18456 automotive catalog or higher-grade PIC18F family.
