PIC16C63AT-20I/SS - 8-bit OTP MCU, 7KB, 20MHz, SSOP-28 | Microchip
MPN: PIC16C63AT-20I/SS ✓ Hoạt độngPIC16C63AT-20I/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and programmable I/O peripherals. Within the broader component taxonomy, an 8-bit MCU belongs to microcontrollers, which fall under integrated circuits and the embedded computing domain. The PIC16C63AT operates from a 4.0 V to 5.5 V supply, features a high-performance RISC CPU, and supports two-cycle program branches (other instructions complete in a single cycle), making it well suited to deterministic real-time control tasks.
Key features include 22 general-purpose I/O pins arranged across multiple ports, hardware peripherals compatible with the PIC16C63A/65B/73B/74B family (Capture/Compare/PWM, USART, and synchronous serial port), and on-chip A/D conversion capability per family datasheet. The -20I temperature grade designates industrial range operation from -40 °C to +85 °C. The 'T' suffix denotes tape-and-reel packaging; the /SS suffix denotes the 28-SSOP outline.
Architecturally, the PIC16C63AT uses a Harvard-style RISC engine and OTP program memory, which is one-time programmable in production - field re-programmability requires the flash-based PIC16F63x or PIC16F87x equivalents. Compared with older PIC16C5x parts, the mid-range core adds interrupts, a hardware stack, and a richer peripheral set while retaining the classic 35-instruction RISC instruction set, easing porting of legacy code.
Typical applications include industrial control, motor control (PWM-driven), embedded serial communications (USART/SPI/I2C via the synchronous serial port), instrumentation, and any 5 V 8-bit embedded system that requires a small-form-factor SSOP-28 footprint. When designing, ensure your programmer supports the OTP device variant and that your firmware revision strategy accounts for one-time-only programming; consider the flash-based PIC16F873A-I/SS for prototypes requiring iteration.

Ứng dụng tiêu biểu
PIC16C63AT-20I/SS phù hợp cho 6 Áp dụngs: Industrial Control & Automation, Motor Control / PWM Drive, Embedded Serial Communications, Instrumentation & Data Acquisition, Consumer Electronics Control Boards, Automotive Body Electronics (Non-Safety).
Industrial Control & Automation
The PIC16C63AT-20I/SS suits factory-floor PLC-style controllers and sensor-interface boards thanks to its 22 GPIO pins, 5 V industrial supply range, and -40 °C to +85 °C operating temperature. The 20 MHz RISC core delivers deterministic 200 ns instruction execution, which is critical for digital control loops and timing-sensitive I/O scans. The 7 KB OTP program memory holds substantial state-machine logic, while the 192 B RAM handles real-time data buffers.
Được đề xuất
Motor Control / PWM Drive
The PIC16C63AT-20I/SS provides hardware Capture/Compare/PWM peripherals that drive brushed DC and stepper motor stages in compact 5 V systems. With 22 I/O and 20 MHz instruction throughput, the MCU generates multiple PWM channels for H-bridge control and quadrature-encoder feedback. The 28-SSOP package keeps the BOM small for tightly-packed motor-driver PCBs, and the industrial temperature grade handles motor housing environments.
Được đề xuất
Embedded Serial Communications
The PIC16C63AT-20I/SS integrates a USART plus a synchronous serial port (SSP) that supports SPI and I2C master/slave operation, making it ideal for sensor hubs and gateway modules that bridge RS-232/RS-485 to SPI peripherals. The 192 B RAM buffers incoming frames before forwarding, while the 35-instruction RISC core executes the protocol stack with predictable timing. Industrial -40 °C to +85 °C support lets the part operate in outdoor enclosures.
Được đề xuất
Instrumentation & Data Acquisition
The PIC16C63AT-20I/SS family integrates a multi-channel A/D converter, making the MCU well suited for low-speed data-acquisition front-ends such as temperature, pressure, and flow loggers. At 20 MHz, the device sequences A/D conversions with deterministic latency, and 22 I/O lines accommodate keypad, LCD, and EEPROM interfacing. The 5 V supply simplifies analog signal-chain design versus 3.3 V MCUs.
Được đề xuất
Consumer Electronics Control Boards
The PIC16C63AT-20I/SS drops into small consumer appliances (washing-machine user-interface boards, HVAC thermostats, security keypads) that need 5 V tolerant I/O and a small PCB footprint. The SSOP-28 package keeps the controller under 14 mm long, and the 7 KB OTP ROM stores fixed-function firmware at minimal unit cost. The industrial temperature rating (-40 °C to +85 °C) handles garage, attic, and outdoor-sheltered environments.
Được đề xuất
Automotive Body Electronics (Non-Safety)
Although automotive under-hood applications require AEC-Q100, the PIC16C63AT-20I/SS still serves non-safety automotive subsystems such as interior lighting controllers, seat-position memory modules, and mirror adjusters. Its 5 V supply, 22 I/O, and -40 °C to +85 °C temperature range match cabin-electronics needs, while the 20 MHz core handles LIN-style software-UART bit-banging where a hardware USART is otherwise occupied.

Ghi chú thiết kế
Estimated: At 20 MHz clock and 5.0 V supply, the PIC16C63AT-20I/SS draws approximately 15-20 mA active Icc, depending on peripheral enable state and I/O loading. Add a 100 nF decoupling capacitor within 10 mm of Vdd (pin 20) and a 10 µF bulk capacitor on the supply rail. The MCU has no internal regulator, so the upstream 5 V rail must remain inside the 4.0 V to 5.5 V operating window or the brown-out reset will fire.
Keep the SSOP-28 land pattern on a 0.65 mm pitch with at least 0.20 mm clearance to adjacent traces for reliable reflow soldering. Route the crystal traces (OSC1/OSC2) short and symmetric, with a ground guard ring around the crystal to reduce EMI coupling into the oscillator. Place /MCLR (pin 1) decoupling (typically 10-100 nF to Vdd) close to the pin to avoid spurious resets during in-circuit programming.
The PIC16C63AT-20I/SS is OTP (one-time programmable) - once programmed, the memory cannot be erased. Engineers developing firmware must use a flash equivalent such as PIC16F873A-I/SS or PIC16F648A-I/SS during prototype bring-up, then port the final code to the OTP device for production. Also confirm that the production programmer (MPLAB PM3 or compatible) supports the PIC16C63AT device ID before committing to high-volume programming runs.
