PIC16LC63-04/SO 개요
What is a PIC16C-family microcontroller? The PIC16CXX is a family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers built around a RISC (Reduced Instruction Set Computing) core. With only 35 single-word instructions to learn and a single-cycle execution architecture (except program branches, which take two cycles), the PIC16 architecture became an industry-standard baseline for embedded control. The PIC16LC63 sits in the mid-range PIC16 family and integrates program memory, data RAM, peripherals, and CPU on a single die - the same architectural category as modern PIC16F1xxx enhanced mid-range devices, but in the original C-series silicon with EPROM/OTP program memory.
Key features include 22 general-purpose digital I/O pins, 3 timer modules, a 10-bit multi-channel Analog-to-Digital Converter (ADC), and serial communication peripherals including USART (asynchronous/synchronous), SSP (I2C/SPI) and a parallel slave port. The device operates from 2.5 V to 5.5 V (commercial 'LC' low-voltage variant), supports 4 MHz maximum clock input, and integrates power-on reset, brown-out reset, watchdog timer with its own on-chip RC oscillator, and in-circuit serial programming (ICSP). The 28-pin SOIC wide-body package enables hand-solderable prototypes and standardized PCB footprints for industrial and consumer embedded designs.
Architecturally, the PIC16LC63-04/SO uses a Harvard bus architecture with separate program and data memories, a 14-bit wide instruction word, and an 8-bit data path. The 'LC' suffix denotes the low-voltage CMOS process optimized for 3.3 V operation, while the '-04' speed grade indicates a 4 MHz maximum oscillator input. The 192-byte data RAM supports register banking across 4 banks, providing rapid context save/restore for interrupt service routines.
Typical applications include industrial automation control, consumer electronics user interfaces, automotive body and HVAC subsystems, sensor signal conditioning nodes, low-power remote sensor terminals, and small-format human-machine interface (HMI) panels. The wide operating voltage range, integrated ADC, and USART make it well-suited for battery-backed sensor hubs and serial-bridge converters.
When designing with this device, budget code space carefully: the 7 KB (4K x 14) OTP memory is one-time programmable, so firmware must be fully debugged in EPROM-window or flash-emulation parts before committing to OTP. The 28-pin SOIC wide package has generous pin pitch (1.27 mm), simplifying rework and breadboarding versus SSOP or QFN variants.

일반적인 애플리케이션
PIC16LC63-04/SO 적합 용도: 6 애플리케이션s: Industrial Automation Controller, Consumer Electronics User Interface, Automotive Body and HVAC Subsystem, Low-Power Remote Sensor Terminal, Serial-Bridge Protocol Converter, Compact HMI Control Panel.
Industrial Automation Controller
The PIC16LC63-04/SO's 7 KB OTP program memory, 22 digital I/O lines, and 10-bit multi-channel ADC make it well suited to industrial automation controllers driving PLC-style ladder-logic emulation or sensor-aggregation nodes. Its 4 MIPS throughput at 4 MHz is adequate for deterministic control loops with cycle times in the 1-10 ms range, while the integrated USART enables reliable RS-232/RS-485 communication with supervisory HMIs. The wide 2.5-5.5 V supply range allows direct connection to both 24 V-derived 5 V rails and 3.3 V logic without level shifters, simplifying mixed-voltage backplane designs.
추천
Consumer Electronics User Interface
The PIC16LC63-04/SO powers mid-tier consumer electronics user interfaces by combining a 10-bit ADC for keypad or resistive-touch scanning, the SSP peripheral for I2C/SPI expansion (display drivers, LED controllers), and 22 I/O lines for matrix keypads and indicator LEDs. The 4 MHz clock supports responsive debounced scanning of 4x4 keypads within 10 ms while leaving headroom for housekeeping tasks. Operating from 2.5-5.5 V allows direct battery or USB-rail connection in portable devices, and the 28-SOIC wide package simplifies hand-solder rework during prototype bring-up.
추천
Automotive Body and HVAC Subsystem
The PIC16LC63-04/SO fits automotive body-electronics and HVAC subsystems where its 10-bit ADC samples thermistor or potentiometer inputs, its USART bridges to dashboard controllers, and its PWM-capable timers drive small fan motors or lighting dimmers. The commercial 0C to +70C operating range covers cabin environments but not under-hood conditions; for under-hood designs migrate to PIC16F73-I/SO (industrial -40C to +85C) or PIC18F equivalents. The OTP program memory locks firmware at production, which is desirable for anti-tamper body-control modules. Wide 2.5-5.5 V supply tolerates 12 V battery drops during cold-crank.
추천
Low-Power Remote Sensor Terminal
Battery-powered remote sensor terminals benefit from the PIC16LC63-04/SO's wide 2.5-5.5 V supply range, integrated 10-bit ADC for environmental telemetry, and USART for low-duty-cycle radio module interfaces. Sleep-mode current and watchdog timer with dedicated RC oscillator enable unattended months-long deployments on two AA cells when paired with a micropower sensor front-end. The 192-byte RAM accommodates small protocol stacks such as Modbus-RTU framing, and the 7 KB OTP memory stores calibration constants and communication logic. The 28-SOIC wide package is field-replaceable for service technicians.
추천
Serial-Bridge Protocol Converter
The PIC16LC63-04/SO serves as a serial-bridge converter (RS-232 to I2C/SPI, or USART to parallel-slave-port) by leveraging its independent USART and SSP peripherals running simultaneously. At 4 MHz the CPU has ample bandwidth to buffer traffic, perform protocol translation, and forward frames between buses at rates up to 115.2 kbps without loss. The 22 I/O pins provide handshake and flow-control signals. Industrial users deploy these bridges to integrate legacy serial-only instruments into modern I2C-controlled systems, and the wide 2.5-5.5 V supply accommodates both legacy 5 V and modern 3.3 V sides without external level shifters.
추천
Compact HMI Control Panel
The PIC16LC63-04/SO is a strong fit for compact human-machine interface panels (appliance controls, instrument front panels, simple kiosks) where it scans keypads, drives character LCDs via I2C expanders, and reports status through its USART to a host controller. Its 22 I/O lines support a 4x4 matrix keypad plus four LED indicators plus an I2C/SPI display bus without external glue logic. The 10-bit ADC reads potentiometer setpoints (volume, temperature), while the 4 MHz clock keeps response times under 50 ms for tactile feel. The 28-SOIC wide-body package is hand-solderable for prototype iterations.

설계 노트
PIC16LC63-04/SO uses One-Time Programmable (OTP) EPROM memory. Once a blank device is programmed, the firmware cannot be erased or modified. Always validate your firmware on a UV-erasable windowed sample (PIC16LC63-04/JW) or migrate to the flash-based PIC16F73-I/SO for development and field updates. Programming should be performed in-circuit via ICSP with Vpp=13.5 V applied to the MCLR pin, observing Microchip's recommended in-circuit serial programming algorithm.
The PIC16LC63-04/SO requires a clean, regulated Vdd supply in the 2.5-5.5 V range. Place a 100 nF decoupling capacitor as close as possible to the Vdd pin (pin 27) plus a bulk 10 uF electrolytic at the board's power-entry point. For battery-powered designs, use a low-dropout regulator such as MCP1700 to maintain stable operation as battery voltage falls below 3 V. The brown-out reset (BOR) module should be enabled in configuration bits to prevent code runaway during voltage droops.
Place the 28-SOIC wide-body footprint on a board with 1.27 mm (50 mil) pin pitch - the SOIC-28 wide package. The exposed pad is not present on this package; thermal dissipation relies solely on the 28 gull-wing leads, so copper-pour on Vdd and Vss traces improves both power delivery and thermal performance. Keep the 4 MHz crystal traces (OSC1/OSC2 pins 8-9) short and shield them from high-current switching signals. For EMI-sensitive applications, place a ground guard ring around the oscillator section.
Allocate dedicated I/O banks for analog and digital signals. Pins RA0-RA5 (pins 1-6) support both digital I/O and analog ADC inputs; configure unused ADC channels as digital outputs to minimize ADC switching noise. The Parallel Slave Port (RD0-RD7, pins 18-19 and 21-26) is multiplexed with PORTD; disable PSP in firmware when not used to free those pins for general I/O. The MCLR pin (pin 7) requires a 10 kohm pull-up to Vdd; do not leave it floating or the device will randomly reset.
