MPN: PIC16LC63A-04I/SO ✓ AktifPIC16LC63A-04I/SO Ringkasan
What is a PIC16C-series microcontroller? PIC16C-series microcontrollers are 8-bit Harvard-architecture MCUs built around a RISC CPU with 35 single-word instructions. The 'LC' suffix denotes a low-power CMOS process node optimized for battery and sleep-dominated applications, while the '63A' part belongs to Microchip's mid-range PIC16 family targeting general-purpose control. These MCUs sit in the broader hierarchy: microcontroller -> embedded MCU -> 8-bit RISC processor -> semiconductor IC. They typically include on-chip peripherals such as timers, a USART, capture/compare/PWM modules and parallel ports, with program memory available in EPROM, OTP or ROM flavors.
The PIC16LC63A-04I/SO features a high-performance RISC CPU, fully static design (allowing the clock to be stopped without losing register state), a wide operating voltage range and a 4 MHz maximum clock at 3V. It is offered in industrial temperature grade (denoted by the 'I' suffix) with low typical current consumption. Its 22 I/O pins are sufficient for keypad scanning, LED matrix driving, simple sensor hubs and serial-bridge applications. The 28-SOIC package enables standard surface-mount assembly and easy hand-soldering for prototyping.
Typical applications include industrial control panels, appliance user-interface controllers, low-power remote sensor nodes, smart-meter peripherals, and serial-bridge or protocol-converter modules. Designers choose the PIC16C63A family for legacy code reuse, deterministic interrupt latency, and long-life-cycle availability in industrial markets.
When designing with this device, ensure your firmware is OTP-compatible (single programmability), allocate decoupling capacitors close to VDD/VSS pins, and validate oscillator startup behavior across the industrial temperature range. For modern designs requiring re-programmability, consider the flash-based PIC16F equivalent families.

Aplikasi Umum
PIC16LC63A-04I/SO cocok untuk 7 aplikasis: Industrial Control Panel MCU, Appliance User-Interface Controller, Low-Power Remote Sensor Node, Smart-Meter Peripheral Controller, Serial Bridge / Protocol Converter, Automotive Under-Hood Auxiliary Module, LED Display and Sign Multiplexer.
Industrial Control Panel MCU
The PIC16LC63A-04I/SO fits industrial control panels because it combines industrial-grade -40C to +85C operation, 22 I/O lines and a USART for keypad/scanner/HMI aggregation. Its 7 KB OTP holds deterministic state machines and serial protocol handlers without the overhead of an RTOS. The 4 MHz clock and 3.0-5.5 V supply let it share the same 5 V rail as optocouplers and 24 V interface ICs.

Appliance User-Interface Controller
For appliance UIs such as washing machines, dishwashers and microwave keypads, the PIC16LC63A-04I/SO offers 22 I/O for matrix-scanned keypads and 7-segment/LED multiplexed displays, plus PWM channels for buzzer tones and indicator dimming. The 4 MHz clock and OTP memory keep BOM cost low while the industrial temp grade survives the heat of enclosed appliance housings.
Direkomendasikan
Low-Power Remote Sensor Node
The 'LC' low-power CMOS process and 3.0 V minimum supply make the PIC16LC63A-04I/SO a candidate for battery-powered remote sensor nodes that wake periodically, sample a sensor over analog or I/O, and transmit via USART to an external radio. The 192-byte RAM is small but adequate for sampled buffers, and the wide voltage range supports 3.3 V coin-cell or Li-Ion chemistries.
Direkomendasikan
Smart-Meter Peripheral Controller
Smart-meter sub-assemblies for electricity, water or gas monitoring benefit from the PIC16LC63A-04I/SO's industrial temp range, 22 I/O for pulse counters and tamper switches, and USART for linking to the main metrology MCU. The OTP memory locks calibration coefficients and security identifiers, preventing firmware tampering in deployed meters.
Direkomendasikan
Serial Bridge / Protocol Converter
The PIC16LC63A-04I/SO's hardware USART plus 22 GPIO makes it well-paired to legacy-to-modern protocol bridges: RS-232 to TTL, RS-485 to UART, or I2C/SPI bit-banged masters to a UART host. The 4 MHz clock delivers enough instruction bandwidth for half-duplex protocol translation at typical 9600-115200 baud rates without handshake dropouts.
Direkomendasikan
Automotive Under-Hood Auxiliary Module
Although not AEC-Q100 qualified, the PIC16LC63A-04I/SO is used in non-safety automotive peripherals such as cabin HVAC flap drivers, mirror controllers and seat-position memories where its -40C to +85C industrial range covers cabin thermal loads. The 22 I/O drives small brushed motors via PWM and reads Hall-effect position sensors through the analog comparator.
Direkomendasikan
LED Display and Sign Multiplexer
Driving 7-segment or dot-matrix LED signs requires many GPIO plus PWM for brightness control - exactly the 22 I/O and PWM peripheral mix of the PIC16LC63A-04I/SO. The 4 MHz clock multiplexes 8-digit displays with acceptable refresh, and the OTP memory holds font tables and scrolling message buffers without needing external EEPROM.

- A-revision silicon with ADC refinements (vsPIC16LC63-04I/SO)

Catatan Desain
Estimated: at 5 V supply, 4 MHz active clock and 22 I/O switching at 100 kHz, the PIC16LC63A-04I/SO typically draws 2-5 mA active plus per-I/O load. Decouple VDD (pin 11) with a 100 nF ceramic placed within 5 mm of the pin, plus a 10 uF bulk tantalum or aluminum polymer on the supply rail. The second VSS pin (28) must be returned to ground; do not leave it floating or ADC readings will degrade.
The 28-SOIC package has a 0.05 inch pitch and 0.295 inch body width. Route MCLR (pin 1) with a 10 kohm pull-up to VDD and a 100 nF cap to ground for clean resets; keep the trace short to avoid false resets from EMI. Place the 4-20 MHz crystal (or ceramic resonator) within 10 mm of OSC1/OSC2 (pins 9/8) with grounded guard traces to suppress noise coupling into the timer/capture peripherals.
OTP parts cannot be re-programmed: once you blow the security fuse or commit code to OTP, any firmware bug requires physical part replacement. Always validate firmware on a windowed CERDIP PIC16C63A-04/JW or an equivalent flash PIC16F73-I/SO emulator before committing to OTP production parts. Brown-out detect (BOD) must be enabled in the configuration word for industrial deployments to avoid latch-up on brown-out events.
The 22 I/O pins share functions with analog inputs and the ICSP programming interface (RB3/RB6/RB7). When using ICSP for in-circuit programming, isolate the PGC/PGD lines from high-speed switching signals to avoid programming glitches. Series 100 ohm resistors on RB6/RB7 improve programming reliability in noisy environments.
