PIC16F630-I/ST - 8-bit MCU, 1.75KB Flash, 20MHz | Microchip
MPN: PIC16F630-I/ST ✓ فعالPIC16F630-I/ST جائزہ
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU, non-volatile program memory (Flash/ROM), volatile data memory (RAM), non-volatile data EEPROM, and peripheral blocks (timers, ADC, comparators, communication ports) on one die. The PIC16F630 belongs to the PIC16F mid-range family, which sits within the broader PIC microcontroller hierarchy and the larger class of 8-bit microcontrollers commonly used where deterministic behaviour, low power, and small footprint outweigh the need for a 32-bit core. Typical application domains include consumer appliances, automotive body electronics, sensor interfaces, and industrial control modules.
Key features include a 20 MHz internal-execution clock, 12 I/O pins with individually selectable direction, a 10-bit successive-approximation ADC, one analog comparator with programmable on-chip reference, one 8-bit and one 16-bit timer, an enhanced watchdog timer, an internal 4 MHz/37 kHz oscillator option, and In-Circuit Serial Programming (ICSP) via two pins. The TSSOP-14 package measures approximately 5.0 mm x 4.4 mm and supports low-cost two-layer PCB assembly.
The device uses Microchip's RISC-based mid-range core executing 35 single-word instructions, with a hardware stack and interrupt controller. Program memory is Flash, supporting in-application reprogramming and ICSP, while the 128-byte EEPROM provides non-volatile data storage for calibration constants, serial numbers, and user settings without external serial EEPROM.
Typical applications include battery chargers, fan controllers, sensor signal conditioners, simple user-interface panels, LED lighting controllers, and remote-control transmitters. The internal oscillator reduces external component count, making the part attractive for cost-sensitive two-layer designs.
When designing with the PIC16F630, note that VDD decoupling requires a 0.1 µF ceramic capacitor close to the pin, and the MCLR reset pin should be tied to VDD through a 10 kΩ resistor for reliable operation. The 12 I/O pins are shared with peripheral functions, so pin-function allocation should be planned during schematic capture.

عام استعمالات
PIC16F630-I/ST کے لیے موزوں ہے 6 ایپلیکیشنs: Battery Charger Controller, Sensor Signal Conditioner, Ceiling Fan / BLDC Motor Controller, LED Lighting Controller, Remote Control Transmitter, Industrial Sensor Interface Module.
Battery Charger Controller
The PIC16F630-I/ST fits battery-charger control loops thanks to its 10-bit ADC for measuring battery voltage and charge current, internal 4 MHz oscillator eliminating external clock parts, and 1.75 KB Flash accommodating CC/CV state-machine firmware. Operating from 2.0 V to 5.5 V VDD lets the same MCU supervise a single-cell Li-ion pack directly off the cell voltage rail after a regulator. The 12 GPIO pins drive status LEDs, relay/MOSFET gate signals, and a temperature-sensor input. Compared with a discrete analog charger, the MCU adds programmable termination, timer-based safety, and field-updatable firmware via ICSP. Use it in cordless tools, e-bike packs, and small UPS modules where cost is critical.

Sensor Signal Conditioner
The PIC16F630-I/ST serves as a low-cost sensor front end that reads analog signals via its 10-bit ADC, applies digital filtering in firmware, and outputs the conditioned value over GPIO or a bit-banged UART. Its 20 MHz core completes a full ADC read plus a 16-tap moving average in microseconds, leaving bandwidth for housekeeping. With 64 bytes of RAM, designers can buffer 8 to 16 samples in a sliding window. The wide 2.0 V to 5.5 V supply lets it run directly from a 3.3 V or 5 V rail, ideal for thermocouple amplifiers, photodiode loggers, and load-cell digitizers in industrial instrumentation.

Ceiling Fan / BLDC Motor Controller
Fan-speed controllers and small BLDC drivers benefit from the PIC16F630-I/ST's analog comparator for zero-cross detection of back-EMF, 16-bit timer for PWM generation, and 35-instruction RISC core that handles 6-step commutation in firmware. The industrial -40 °C to +85 °C temperature grade covers attic and outdoor-ducted installations. With 1.75 KB Flash, the firmware fits start-up ramps, tachometer feedback, and IR remote decoding for ceiling fans, range hoods, and small appliance motors. The TSSOP-14 footprint keeps the MCU off the heatsink, while internal oscillator parts-count minimization aids BOM cost.

LED Lighting Controller
The PIC16F630-I/ST drives LED lighting strips and indicator panels via PWM on its 16-bit timer, providing 10-bit dimming resolution at modest update rates. Its 12 GPIO pins can sink RGB channels directly through MOSFETs, and the 10-bit ADC reads ambient-light sensors for daylight harvesting. Operating from 2.0 V to 5.5 V allows battery-powered decorative lighting or 24 V commercial fixtures after regulation. The 1.75 KB Flash comfortably stores breathing-light patterns, push-button handling, and IR remote maps. Industrial temperature grade suits outdoor signage and architectural lighting installations.

Remote Control Transmitter
The PIC16F630-I/ST is well suited to IR/RF remote control transmitters because it can scan a 4x4 matrix keypad with only 8 GPIO pins, bit-bang a 38 kHz carrier via the 16-bit timer, and enter sleep between button presses to extend battery life. Its internal 4 MHz / 37 kHz oscillator options minimize external parts, and 128 bytes of EEPROM store paired-device IDs. At 2.0 V minimum VDD it runs from two AAA cells directly. The TSSOP-14 footprint is small enough for handheld TV remotes, fan controllers, and smart-home key fobs.

Industrial Sensor Interface Module
The PIC16F630-I/ST functions as a low-cost industrial sensor interface, digitizing 4-20 mA loop signals or 0-10 V analog inputs via its 10-bit ADC, linearising in firmware, and presenting results over a UART bit-banged on GPIO. The 20 MHz core handles Modbus-style framing or custom protocols, while the 128-byte EEPROM stores calibration coefficients for the life of the module. Operating from -40 °C to +85 °C and 2.0 V to 5.5 V it tolerates plant-floor conditions. The TSSOP-14 package sits comfortably on 25 mm x 25 mm sensor PCBs used in process control and building automation.

ڈیزائن نوٹس
Place a 0.1 µF ceramic decoupling capacitor as close as possible to the PIC16F630-I/ST VDD pin (pin 1) and a bulk 1 µF to 10 µF tantalum or ceramic on the same VDD trace. The TSSOP-14 lead inductance can ring at >100 MHz edges, so keep the loop area below 5 mm². For battery-powered designs using the internal oscillator, expect average active current around 0.5 mA at 4 MHz / 5 V and sleep current below 1 µA with the watchdog disabled, suitable for coin-cell sensor nodes.
Route the ICSP clock (RB6/ICSPCLK) and data (RB7/ICSPDAT) lines with 1 kΩ series resistors close to the MCU to allow in-circuit programming after PCB assembly. Ensure the MCLR pull-up (typically 10 kΩ) is present and that no low-impedance load on MCLR would prevent the programming voltage from rising above Vih. Keep the ICSP connector at least 5 mm from any switching converter to avoid coupling noise into the programming lines.
Do not leave the MCLR pin floating - either tie it to VDD through a 10 kΩ resistor (with a capacitor to ground for noise filtering), or configure it as a reset input in the configuration bits. Floating MCLR causes erratic resets in noisy environments. Also, when using the internal oscillator, set the IRCF configuration bits correctly; selecting a higher frequency than VDD supports results in out-of-spec operation and possible Flash corruption during write cycles. Always read the configuration-word settings table in the datasheet before generating firmware.
The TSSOP-14 thermal pad is not present on this package; however, copper pour under the device still helps dissipate short-term transients and improves EMI. Keep analog input traces (RA0-RA2) short and away from digital switching lines such as PWM or oscillator traces. If using the ADC, add a 100 nF + 10 µF decoupling pair on AVDD if AVDD is brought out, or share VDD with a ferrite bead for noise isolation.
