PIC16C63A-04E/SP 概要
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, data RAM, and peripherals on one die; the PIC mid-range core uses a Harvard RISC architecture with 35 single-word instructions, only one of which (program branch) takes two cycles, while the rest execute in a single instruction cycle. This design simplifies coding while delivering deterministic interrupt latency that is critical for real-time embedded control.
Key features of the PIC16C63A-04E/SP include 22 digital I/O pins, three serial communication peripherals (I2C, SPI, and UART/USART), Capture/Compare/PWM (CCP) modules for motor and lighting control, an 8-bit ADC, and Brown-out Detect/Reset plus Power-On Reset (POR) for robust supply supervision. The 'E' suffix designates the Extended industrial temperature range of -40C to +125C, while '04' denotes a 4 MHz maximum oscillator frequency.
Architecturally, the PIC16C63A uses a 14-bit instruction word with separate code and data buses, allowing simultaneous instruction fetch and data access. Its CMOS static design means the clock can be stopped and the device put into Sleep mode for ultra-low standby power, making it well-suited for battery-backed or energy-conscious industrial applications.
Typical applications include industrial control logic, sensor interface boards, motor control subsystems, automotive body electronics (non-safety), and legacy embedded systems requiring long-term parts continuity. The OTP memory and SPDIP package also make this part attractive for through-hole prototyping and low-volume production runs.
When designing with the PIC16C63A-04E/SP, ensure the oscillator circuit uses the correct crystal or resonator values for the chosen clock frequency (4 MHz max), and always place decoupling capacitors within 5 mm of the VDD pins. Because this part is OTP, firmware must be fully validated before programming; for in-system reprogrammability, consider the Flash-based PIC16F73/74 equivalents.

主な用途
PIC16C63A-04E/SP の用途: 6 件s: Industrial Control Logic, Motor Control Subsystems, Sensor Interface Boards, Automotive Body Electronics, Legacy Embedded Replacement, HMI Keypad and Display Interface.
Industrial Control Logic
The PIC16C63A-04E/SP's 22 digital I/O, three serial peripherals (I2C/SPI/UART), and Extended -40C to +125C temperature range make it well suited for industrial control logic boards that must survive harsh factory environments. Its 7 KB OTP holds substantial state-machine code for relay drivers, sensor multiplexing, and HMI button scanning. The Brown-out Detect and Power-On Reset ensure deterministic startup on noisy 24V/5V industrial rails, while the 4 MHz clock provides 1 us instruction cycle time that is sufficient for sub-millisecond control loop updates typical of PLC I/O modules.
おすすめ
Motor Control Subsystems
The Capture/Compare/PWM (CCP) module on the PIC16C63A-04E/SP generates the PWM signals needed for small DC and stepper motor drives up to a few hundred Hz switching frequency. With 4 MHz CPU clock and 1 us instruction cycle, the firmware can update PWM duty cycle and process quadrature encoder feedback in real time. The 22 I/O pins can drive H-bridge logic, read end-of-travel switches, and run the serial diagnostic channel back to a host controller. For higher PWM frequencies, the 20 MHz PIC16C63A-20/SP sibling provides 200 ns instruction cycles.
おすすめ
Sensor Interface Boards
The PIC16C63A-04E/SP integrates I2C, SPI, and USART peripherals on-chip, allowing direct connection to digital temperature sensors, accelerometers, EEPROMs, and RS-485 transceiver front-ends without external glue logic. Its 192 bytes of RAM are sufficient to buffer multi-sensor scan frames and run simple digital filtering (moving average, hysteresis) before reporting over the UART. The PIC16C63A-04E/SP's Extended -40C to +125C range enables outdoor and under-hood sensor hubs. For designs needing higher-throughput sensor I/O, migrate to the 20 MHz grade.
おすすめ
Automotive Body Electronics
The PIC16C63A-04E/SP is a common choice for non-safety automotive body modules such as seat controllers, mirror adjusters, interior lighting, and door-lock actuators where AEC-Q100 qualification is not strictly required. Its 4 MHz CPU, 22 I/O, and PWM module can drive small solenoids and lamp dimmers; its Extended -40C to +125C range covers cabin and under-hood thermal stress. For designs requiring formal AEC-Q100 compliance, migrate to a Q-graded PIC such as PIC16F73-I/SP which carries automotive PPAP documentation.
おすすめ
Legacy Embedded Replacement
The PIC16C63A-04E/SP is widely specified in long-lifecycle industrial products originally designed in the late 1990s, where manufacturers need a pin-compatible 28-SPDIP MCU to keep legacy boards in production. Because the PIC16CXX mid-range architecture and instruction set have remained stable, existing firmware (assembled for PIC16C6X) typically runs without modification when ported from earlier PIC16C63 to PIC16C63A silicon. The OTP memory and Extended temperature range make this part attractive for low-volume industrial control boards, vending machines, and test fixtures where in-field reprogrammability is not required.
おすすめ
HMI Keypad and Display Interface
The PIC16C63A-04E/SP's 22 digital I/O are enough to scan a 4x4 or 5x5 matrix keypad (16-25 keys) and drive a character LCD through parallel PORTB/C interfacing. Its 4 MHz clock supports debounce timers, key repeat logic, and SPI control of LCD modules with sub-millisecond response. The Brown-out Detect prevents false key entries during power-down. This part is a popular choice for industrial panel meters, access-control keypads, and small appliance user interfaces where cost and Extended temperature range matter more than high CPU throughput.

設計ノート
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of pin 10 and a second 10 uF tantalum or aluminum bulk capacitor near the MCU. The PIC16C63A-04E/SP can source/sink up to 25 mA per I/O pin (100 mA total VDD/200 mA total VSS), so design the 5 V rail to handle peak transient current when multiple outputs switch simultaneously. The Brown-out Detect voltage is configurable; program BOREN to enable a clean reset on a sagging industrial 5 V rail.
Route the MCLR line directly from the supervisor or RC reset network to pin 1 with no stubs; a long MCLR trace can pick up noise that falsely resets the MCU. Keep the OSC1/OSC2 crystal traces short and symmetric, and place the load capacitors within 5 mm of pins 8-9. Use a ground plane under the MCU to reduce EMI; for noisy industrial environments add a ferrite bead in series with VDD.
Because PIC16C63A-04E/SP is OTP, firmware bugs cannot be field-reprogrammed. Always validate the hex file on a windowed CERDIP version (PIC16C63A/JW) or a Flash-based sibling (PIC16F73-I/SP) before committing to OTP programming. Note that the PIC16C63A 'A' silicon revision adds the dedicated USART baud-rate generator; code written for PIC16C63 (no 'A') using software baud-rate generation still runs on PIC16C63A but you must re-verify timing.
コンプライアンス情報
Compliance status not visible in the Verified Web Data snippet. PIC16C63A is a legacy mid-range MCU family; for new designs requiring RoHS/REACH compliance, verify the specific date code with Microchip or request a CoC from the distributor.
