PIC16F630T-E/SL - 8-bit 20MHz MCU 1.75KB Flash SOIC-14 | Microchip
MPN: PIC16F630T-E/SL ✓ Hoạt độngPIC16F630T-E/SL Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and peripheral functions such as timers, comparators, and I/O ports. The PIC16F630 belongs to Microchip's PIC16 mid-range family — a category hierarchy of 8-bit microcontroller -> RISC MCU -> embedded controller -> semiconductor. Mid-range PIC MCUs use a 14-bit instruction word architecture optimized for deterministic interrupt response and small code size, supporting only 35 single-word instructions for simplified embedded firmware development.
Key features include a 20 MHz internal/external oscillator, 12 I/O pins with individual direction control, a hardware 8-bit timer (Timer0) plus a 16-bit Timer1, one analog comparator with selectable reference, brown-out reset (BOR), power-on reset (POR), watchdog timer (WDT), and an in-circuit serial programming (ICSP) interface. The device operates across 4.5 V to 5.5 V and consumes a few mA in active mode with nanoampere sleep currents suitable for battery-aware designs.
Typical applications include low-cost consumer appliances, automotive body electronics (interior lighting, sensor conditioning), industrial control logic, battery chargers, simple sensor interfaces, and remote-control transmitters. The compact 14-pin SOIC footprint and 35-instruction RISC core make it attractive for high-volume cost-sensitive products requiring reliable field upgradability via Flash.
When designing with this MCU, ensure decoupling on VDD, observe the 4.5 V minimum supply requirement, and allocate adequate Flash headroom for bootloaders or future firmware updates. For new designs consider the suggested Microchip newer-device replacement PIC16F18324, which adds enhanced peripherals while preserving pin compatibility.

Ứng dụng tiêu biểu
PIC16F630T-E/SL phù hợp cho 6 Áp dụngs: Automotive Body Electronics, Battery-Powered Sensor Node, Industrial Control Logic, Consumer Appliance Controller, LED Lighting Driver, Remote Control Transmitter.
Automotive Body Electronics
The PIC16F630T-E/SL suits automotive body modules such as interior LED drivers, mirror controllers, and seat-occupancy sensors where 5 V operation across -40 C to +125 C (E grade) is required. With 12 I/O pins, one analog comparator for sensor threshold detection, and brown-out reset for crank-cycle voltage drops, it reliably handles body-network loads. The 20 MHz core executes ~5 MIPS, sufficient for PWM dimming loops and LIN-slavish bit-banged interfaces. Power-on reset (POR) plus WDT protect against lockup during load-dump transients.

Battery-Powered Sensor Node
For battery-powered wireless sensor or remote-control applications the PIC16F630T-E/SL offers Sleep-mode currents in the nanoampere range plus a wake-on-pin-change interrupt. Its 5 V operation pairs with a boost converter from a single Li-coin cell, while the 1.75 KB Flash comfortably fits sensor-fusion plus RF protocol stack snippets. The 128-byte EEPROM stores calibration constants across power cycles. Brown-out reset prevents corrupted Flash writes at end-of-life battery voltage.
Được đề xuất
Industrial Control Logic
Industrial control logic — relay drivers, opto-isolated input conditioning, simple PLC sub-blocks — fits the PIC16F630T-E/SL well thanks to its E-grade temperature range and proven PIC16 mid-range architecture. Twelve I/O pins multiplex to multiple relay banks; the analog comparator implements zero-cross or current-sense threshold detection. WDT and BOR combined provide the robustness needed in noisy 24 V cabinet environments. ICSP allows firmware patching without removing the controller from the field.

Consumer Appliance Controller
Small kitchen and home appliances — coffee makers, blenders, rice cookers, fan controllers — leverage the PIC16F630T-E/SL's small footprint, 35-instruction RISC core, and Flash upgradability. The 20 MHz core easily handles keypad scanning, triac zero-cross timing, and temperature control loops using the analog comparator with on-chip reference. The 14-SOIC package fits densely populated appliance PCBs. EEPROM retains user-set preferences across power cycles.
Được đề xuất
LED Lighting Driver
LED driving circuits — architectural strips, signage, decorative lighting — use the PIC16F630T-E/SL for constant-current PWM control at modest brightness levels. The 8-bit Timer0 generates PWM frequencies above 1 kHz to avoid flicker; the comparator monitors LED current via a sense resistor and provides hardware over-current protection. With 12 I/O pins a single MCU drives up to three RGB channels. The wide temperature range suits outdoor luminaires in cold or hot climates.
Được đề xuất
Remote Control Transmitter
RF/IR remote controls, key fobs, and wireless keypads benefit from the PIC16F630T-E/SL's tiny 14-SOIC footprint, ultra-low Sleep current, and ICSP field programming. The MCU generates ASK/FSK carrier waveforms using Timer0 PWM while bit-banging the RF encoder data stream. Comparator-based low-battery detection warns the user when to replace cells. The E temperature grade supports automotive key-fob environments down to -40 C.

Ghi chú thiết kế
Estimated: at 5 V supply and 20 MHz active operation the PIC16F630T-E/SL draws approximately 5-8 mA. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 14, plus a bulk 10 uF tantalum or aluminum near the regulator. Brown-out reset should be enabled in configuration bits (BOREN = 1) so that the MCU resets cleanly when VDD dips below ~4.0 V, preventing Flash corruption. Add a ferrite bead on VDD if the supply shares noisy relay drivers.
Route MCLR (pin 3) with a 10 kohm pull-up to VDD and place a 100 nF cap to ground if long cables attach, preventing spurious resets from EMI. Keep the ICSP traces (PGC/PGD) short and avoid running them parallel to switching nodes. The 14-SOIC land pads should follow the JEDEC MS-012 footprint with 1.27 mm pitch; for hand-prototyping use SOIC-to-DIP adapter boards. Exposed thermal considerations are minimal due to low power dissipation.
Do not confuse the T-suffix (tape-and-reel packaging) with a temperature-grade change; PIC16F630T-E/SL retains the E-grade -40/+125 C range. Configuration bits (CONFIG register) must be programmed correctly — disable the watchdog only if the firmware loop is proven reliable. When migrating to PIC16F18324 (newer replacement) verify the oscillator configuration bits and CCP pin mapping differ; do not assume a transparent drop-in.
For external clock input (RA5/OSC1), keep the trace shorter than 20 mm and surround with a ground guard ring to suppress ringing. Internal 4 MHz RC oscillator is factory calibrated to within 1 percent per Microchip datasheet 40044G; for UART or USB timing, use a crystal on RA4/RA5. Add a 10-22 pF load capacitor to ground on each oscillator pin matching the crystal manufacturer's spec.
