PIC16C63-10/SO - 8-Bit 10MHz OTP MCU 7KB | Microchip
MPN： PIC16C63-10/SO ✓ 啟用中PIC16C63-10/SO 概覽
An 8-bit microcontroller (MCU) is a small computer-on-a-chip integrating a CPU, program memory (ROM/OTP/Flash), data memory (RAM), and peripheral interfaces on a single die. PIC microcontrollers use a Harvard RISC architecture that executes most instructions in a single clock cycle, placing them in the broader taxonomy: microcontroller -> embedded processor -> semiconductor -> integrated circuit. The OTP variant is programmed once and is well suited to cost-sensitive, high-volume production where firmware is fixed.
Key features of the PIC16C63-10/SO include 10 MHz operation, a wide supply voltage range of 4.0 V to 6.0 V, 22 I/O lines, integrated capture/compare/PWM and USART peripherals, and very low power consumption (typical 15 uA at 5 V / 4 MHz). The device carries 35 single-word RISC instructions, with all instructions completing in one cycle except program branches which take two.
The architecture is fully static, allowing the clock to be stopped without losing internal state. Commercial, Industrial, and Extended temperature grades are available, supporting both benign and harsh operating environments. The 28-SOIC wide (7.50 mm) package balances I/O count with board-friendly surface-mount assembly.
Typical applications include appliance control, security and alarm panels, industrial sensor conditioning, automotive body electronics, and general-purpose embedded control boards. The PIC16C6X peripheral set - timers, CCP, USART, and parallel I/O - addresses most small-form-factor control tasks without external glue logic.
When designing with this MCU, ensure decoupling is placed within 5 mm of VDD, and that MCLR is pulled up correctly via a resistor and (optionally) a diode to VDD for reliable reset. The OTP memory means firmware must be 100% verified before programming - allocate extra prototype cycles using the windowed (JW) variant during development.
This page synthesizes distributor pricing, drop-in alternatives from the same Microchip PIC16C6X family, and practical design notes not found in the standalone manufacturer datasheet - giving engineers a faster path from selection to production.

典型應用
PIC16C63-10/SO 適用於 6 應用s: Appliance Control Boards, Security and Alarm Panels, Industrial Sensor Signal Conditioning, Automotive Body Electronics, Consumer Audio/Video Remote Controls, General-Purpose Embedded Control Boards.
Appliance Control Boards
The PIC16C63-10/SO is well suited to appliance control boards (washing machines, dishwashers, microwave ovens, HVAC controls) where fixed firmware, low cost, and reliable 5 V operation are essential. Its 7 KB OTP program memory holds typical appliance state machines, motor control sequences, and user-interface logic; 22 I/O lines drive relays, triac optocouplers, keypad scanning, and seven-segment or LCD displays. The 10 MHz clock supports 100 ns instruction timing, fast enough for brushed-DC motor PWM via the on-chip CCP module at 10-20 kHz with adequate resolution. Industrial temperature variants (-10I grade) handle under-cabinet or garage environments. Compared to Flash alternatives, the OTP cost per unit is lower, justifying the lack of firmware revision capability on a sealed production board.

Security and Alarm Panels
Alarm control panels benefit from the PIC16C63-10/SO's combination of 22 I/O for zone inputs, siren/keypad outputs, and a USART for central-station dialer communication. The 192-byte RAM holds the event buffer and zone status; the 7 KB OTP holds sensor debounce, arming logic, and communication protocols (Contact ID, SIA). Low-power operation (typical 15 uA at 5 V / 4 MHz and 1 uA at 32 kHz sleep) extends backup-battery runtime during AC loss. The wide 4.0-6.0 V VDD range tolerates battery voltage droop during discharge. Industrial -40C to +85C temperature variants survive garage and attic installations. OTP memory prevents firmware tampering in the field - an advantage versus Flash MCUs in security applications.
推薦
Industrial Sensor Signal Conditioning
Industrial 4-20 mA loop transmitters, RTD/thermocouple conditioners, and bridge-sensor front-ends often use the PIC16C63-10/SO as a digital linearization and HART-protocol controller. The 10 MIPS throughput at 10 MHz executes polynomial compensation and digital filtering in real time. 22 I/O interfaces 16-bit sigma-delta ADCs (e.g., ADS1256 via SPI) and 4-20 mA DACs; the USART provides HART modem communication at 1200 bps. Wide VDD (4.0-6.0 V) and industrial temperature variants suit 24 V loop-powered applications with regulators. OTP memory locks calibration coefficients and OEM-proprietary algorithms from reverse engineering, and the 28-SOIC package handles -40C to +85C field sites.
推薦
Automotive Body Electronics
In automotive body electronics (window lifts, mirror adjusters, seat controllers, lighting modules), the PIC16C63-10I/SO industrial variant supports -40C to +85C cabin temperatures with adequate margin. The 22 I/O drive H-bridge drivers, MOSFET gate controls, and LIN/CAN bus transceivers (via USART bit-banged or external controller). The 7 KB OTP holds fixed-feature firmware - a regulatory and cost win versus Flash in high-volume body modules. Load-dump voltage transients on the 12 V bus are filtered upstream to bring VDD within the 4.0-6.0 V window. The 28-SOIC surface-mount package supports automated PCB assembly in production lines. Note: for under-hood or AEC-Q100 qualified designs, migrate to PIC16F or PIC18 automotive families.
推薦
Consumer Audio/Video Remote Controls
The PIC16C63-10/SO fits IR remote controls, headphone amplifiers, and small audio/video accessories where cost per unit dominates the BOM. The 7 KB OTP stores IR protocol codes (RC5, NEC, Sony SIRC), button matrix decoding, and LED indicator logic. Low sleep current (1 uA at 32 kHz) preserves battery life - critical for handheld remotes using two AAA cells regulated to 5 V. The 22 I/O scan 4x5 key matrices with no external decoder. The 28-SOIC wide package allows hand-soldering on through-hole hybrid boards used in low-cost consumer products. The 4.0-6.0 V VDD range covers regulated and lightly-loaded battery conditions. Drop-in to PIC16C63-04I/SO if 4 MHz suffices, saving power.
推薦
General-Purpose Embedded Control Boards
Education, prototyping, hobbyist, and small-OEM control boards use the PIC16C63-10/SO as a general-purpose 8-bit controller. Its 35-instruction RISC set is approachable for students, and the 28-SOIC package fits standard DIP-adapter PCBs. The integrated USART enables serial debug output at 9600/115200 baud. 22 I/O are sufficient for course labs covering PWM, interrupts, and I/O expansion via 74HC595 shift registers. The 10 MHz clock supports tight control loops (e.g., 1 kHz PID at 100 microsecond sample period). The 7 KB OTP forces disciplined firmware management - a teaching benefit. Microchip's MPLAB X IDE and XC8 compiler support the entire PIC16C6X family, with abundant application notes and reference code available online.

主要差異化特點
- Lower-cost OTP variant with same pinout as Flash PIC16F876 (對比PIC16F876-10I/SO)
- Mid-range 10 MHz speed grade balances cost and performance (對比PIC16C63-04/SO)
- Mature, well-documented PIC16C6X architecture (對比PIC16C63A-10/SO)
設計說明
The PIC16C63-10/SO requires a regulated 5 V supply within 4.0-6.0 V. Place a 100 nF decoupling capacitor within 5 mm of VDD (pin 19) and a bulk 10 uF tantalum or aluminum polymer capacitor at the board power entry. The MCLR pin (pin 1) must be pulled up to VDD through a 10 kohm resistor; if in-circuit programming is desired, add a diode from MCLR to VDD (cathode on VDD side) to prevent programming voltage back-feed. Brown-out detection is supported via configuration bits - enable BOR for reliable reset in noisy industrial environments.
For the 28-SOIC (0.295 inch wide-body) package, allow 7.50 mm land pad width with 1.27 mm pitch. Route crystal traces (OSC1 pin 8 / OSC2 pin 9) symmetrically with short, equal-length connections to the crystal or ceramic resonator case ground, and keep clock traces away from I/O switching lines. Use a ground pour on the top layer stitched with vias around the crystal to minimize EMI. If using the internal RC oscillator, OSC1/OSC2 pins become RA7/RA6 I/O and can be repurposed; otherwise leave them with the resonator network.
Do not assume the OTP variant can be reprogrammed - it cannot. Verify firmware on the JW (windowed CERDIP) variant during development, then move to PIC16C63-10/SO only for production. Configuration bits (oscillator selection, watchdog timer enable, code protection) must be set correctly at programming time - an incorrect oscillator configuration (e.g., HS vs XT) prevents the part from running. Code-protect bits lock the OTP memory from external read-back - enable for production to prevent firmware theft. The PIC16C63 lacks a 10-bit ADC; if you need analog input, use PIC16C67 (with ADC) or migrate to PIC16F876 (Flash + 10-bit ADC) - both are pin-compatible.
The PIC16C63-10/SO is a CMOS digital IC with negligible self-heating; thermal management is not required. Operating junction temperature is constrained by the ambient temperature grade (0C to +70C for the -10 commercial suffix; -40C to +85C for -10I industrial). For high-altitude or sealed-enclosure designs, derate the upper ambient limit by 5-10C to account for reduced convective cooling. The 28-SOIC package has a typical theta_JA of ~80 C/W in still air, but in practice the device consumes so little power that the package thermal limit is never approached.
