PIC16F630T-E/ST Overview
What is an 8-bit Flash microcontroller? It is a single-chip computer based on a reduced instruction set computing (RISC) architecture with on-chip non-volatile Flash program memory, RAM, and peripherals. Within the broader semiconductor hierarchy, 8-bit MCUs sit below 16-bit and 32-bit MCUs in computing capability but above fixed-function ASICs in flexibility, making them the workhorse of cost-sensitive embedded control. PIC microcontrollers from Microchip use a Harvard architecture, separating program and data buses for deterministic execution, and form part of the wider microcontroller -> embedded processor -> semiconductor taxonomy.
Key features of this device include nanoWatt power-management technology for low standby current, an internal 4 MHz oscillator with software calibration, a wide 2.0V to 5.5V supply range, an internal voltage reference, and one comparator with programmable on-chip reference. The PIC16F630T-E/ST suffix encodes tape-and-reel packaging (T), extended temperature (E), and the TSSOP-14 (ST) package outline. The TSSOP-14 footprint measures approximately 5.0 mm x 4.4 mm, making it ideal for space-constrained designs.
At the architecture level, the device uses a 14-bit instruction word with an 8-bit data path, 8-level hardware stack, and direct/indirect addressing modes. The Flash memory supports in-circuit serial programming (ICSP) via two pins (RB6/ICSPCLK, RB7/ICSPDAT), enabling firmware updates without removal from the board. Programmable code protection and a watchdog timer with on-chip low-power RC oscillator provide reliability for unattended embedded deployments.
Typical applications include consumer appliance control, sensor signal conditioning, battery-powered remote controls, LED lighting controllers, and small motor or fan control loops. The extended temperature grade supports industrial and outdoor installations. Engineers often pair this MCU with MCP1700 LDOs, MCP6002 op-amps, or AT24C EEPROMs to build compact analog-plus-digital signal chains.
Design consideration: at 20 MHz and 5.5V VDD the supply current reaches approximately 11 mA typical; below 4 MHz the device enters nanoWatt sleep modes drawing microampere-level standby current. Choose between 20 MHz operation for compute-heavy tasks and 32 kHz internal oscillator for ultra-low-power timing applications. The ICSP pins must be reserved even in production layouts for in-field firmware updates.

Typical Applications
PIC16F630T-E/ST is suitable for 6 applications: Consumer Appliance Control, Battery-Powered Remote Control, Industrial Sensor Signal Conditioning, LED Lighting Controller, Small Motor and Fan Control, IoT Sensor Edge Node.
Consumer Appliance Control
The PIC16F630T-E/ST is well suited to consumer appliance control boards such as coffee makers, microwave oven keypads, washing-machine front panels, and dishwasher user interfaces where cost and reliability dominate the bill of materials. Its 14-pin TSSOP footprint keeps PCB area below 50 mm^2, and the 1.75 KB Flash comfortably holds a state-machine plus user-interface handler in C or PIC assembly. The 12 I/O pins drive 7-segment displays, keypads, triac optocouplers, and relay coils directly without external logic. With extended -40C to +125C operation, the part survives the thermal stress inside an appliance housing where ambient can reach 90C near the heating element.
Recommended
Battery-Powered Remote Control
The PIC16F630T-E/ST fits battery-powered remote control and wireless key-fob designs where standby current must drop below 10 microamps. The nanoWatt sleep mode disables the CPU core while leaving the watchdog and interrupt-on-change logic active, allowing a coin-cell to last 3-5 years. The internal 4 MHz oscillator eliminates the external crystal and its two load capacitors, reducing BOM cost by $0.10-$0.20. The 12 I/O pins support a 4x4 keypad matrix or an IR LED driver plus multiple tactile-button inputs. Operating voltage from 2.0V to 5.5V allows direct drive from two AA cells or a single CR2032 with an LDO.
Recommended
Industrial Sensor Signal Conditioning
Industrial sensor signal conditioning boards use the PIC16F630T-E/ST as the local decision element for thermostat endpoints, gas detector front-ends, and process-control limit switches. The integrated analog comparator with programmable on-chip voltage reference directly compares a sensor bridge against a calibrated threshold without needing an external op-amp. The TSSOP-14 form factor supports dense PCB layouts alongside 4-20 mA loop interfaces, while the extended -40C to +125C temperature range meets outdoor and factory-floor requirements. The ICSP interface on RB6/RB7 permits firmware calibration adjustments during factory trim without desoldering the MCU.
Recommended
LED Lighting Controller
Small-form-factor LED lighting controllers including architectural strips, decorative fixtures, and RGB accent lights use the PIC16F630T-E/ST to drive PWM dimming and chase patterns. The 16-bit timer with PWM mode generates frequency-correct dimming signals at audio-band rates above 20 kHz to avoid flicker artifacts. The 12 I/O pins independently drive three or four LED channels with MOSFET gates through the MCU outputs, supporting per-channel PWM dimming. The 20 MHz instruction cycle leaves ample CPU headroom to compute logarithmic brightness curves or run DMX-512 receive logic in software.
Recommended
Small Motor and Fan Control
Brushless DC fan controllers, small DC motor speed regulators, and solenoid-driven valve controllers use the PIC16F630T-E/ST for closed-loop RPM or position feedback. The 16-bit timer captures tachometer pulses from a Hall-effect sensor, while PWM outputs drive the gate of a low-side N-channel MOSFET switching the motor winding. The integrated comparator compares back-EMF against a reference for sensorless BLDC commutation in simple two-pole fan applications. The TSSOP-14 package and 20 MHz CPU comfortably fit a sensorless BLDC algorithm in less than 1 KB of Flash.
Recommended
IoT Sensor Edge Node
IoT sensor edge nodes for building automation and agricultural monitoring pair the PIC16F630T-E/ST with a low-power radio module to create battery-endurance sensor beacons. The MCU aggregates temperature, humidity, and switch-state inputs and transmits via SPI or UART to a sub-GHz transceiver in the 868/915 MHz band. Sleep current below 1 microamp in deep-sleep mode lets a 2400 mAh AA battery last 5+ years on a 5-minute reporting interval. The TSSOP-14 footprint is small enough for coin-cell-sized sensor tags, and the extended temperature range handles outdoor deployment in agricultural and greenhouse installations.

Design Notes
The PIC16F630T-E/ST operates from 2.0V to 5.5V VDD. Estimated: at 20 MHz and 5.5V, the active supply current reaches approximately 11 mA typical. For battery applications, drop the clock to 4 MHz (internal oscillator) to reduce active current to about 1.4 mA, and use the SLEEP instruction with the watchdog disabled to drop standby current below 1 microamp. Place a 100 nF decoupling capacitor within 5 mm of VDD pin 1, plus a 10 uF bulk capacitor at the regulator output if the supply traces exceed 25 mm.
Pins RB6 and RB7 are shared with the ICSP programming interface (ICSPCLK and ICSPDAT). Never pull these pins to ground or to VDD through a low-impedance path during normal operation; use at least 4.7 kohm series resistance if the application drives these pins, or the ICSP programmer will be unable to communicate. Pin RA3/MCLR must have a 10 kohm pull-up to VDD; do not leave it floating, or the part will reset continuously. Always include a 100 nF capacitor on VDD within 5 mm of the package.
The TSSOP-14 (ST) package has a 0.65 mm lead pitch and thermal pad-free bottom. Reserve at least 0.30 mm clearance from package edges for solder mask dam, and use a reflow profile with peak temperature not exceeding 250C for lead-free (JEDEC J-STD-020). For ICSP, route the ICSPCLK and ICSPDAT signals to a 2x3 or 1x6 header with ground on pin 6; adding ESD protection diodes on these pins is optional but recommended for field-programmable products. Ground plane stitching vias should be placed every 10 mm around the MCU for EMI suppression.
When using the internal 4 MHz oscillator, avoid routing the OSC1/OSC2 pins next to switching nodes such as PWM outputs or relay drivers; capacitive coupling can inject jitter into the internal oscillator. For sensitive analog applications using the on-chip comparator, route the C1IN+ and C1IN- inputs as short and symmetrical as possible, with a ground guard ring on both sides to reject switching noise from the digital I/O. Pin 14 VSS is the ground reference for the comparator; keep the VSS trace wide and direct to the decoupling capacitor ground.
Compliance Information
RoHS compliant per Microchip product page. Lead-free matte-tin finish. Not AEC-Q100 qualified - automotive designs should consider PIC16F630-E/ST-Q1 or PIC16F1826-I/ST for automotive-grade alternatives.
