PIC16C63AT-20I/SS 개요

The Microchip Technology PIC16C63AT-20I/SS is an 8-bit RISC CMOS one-time-programmable (OTP) microcontroller from the PIC16CXX mid-range family, supplied in a 28-pin SSOP (5.30 mm body width) package. The device integrates 7 KB of program memory (4K x 14 OTP), 192 bytes of RAM, and 22 digital I/O pins, and executes instructions at 20 MHz maximum clock speed with a 200 ns instruction cycle, supporting 35 single-word instructions for fast code development.

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.

일반적인 애플리케이션

PIC16C63AT-20I/SS 적합 용도: 6 애플리케이션s: 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.

⚡

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.

🌐

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.

🔧

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.

📱

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.

🚗

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.

What is the PIC16C63AT-20I/SS?
The PIC16C63AT-20I/SS is a Microchip Technology 8-bit RISC OTP microcontroller in the PIC16CXX mid-range family, with 7 KB of program memory, 192 bytes of RAM, 22 I/O pins, and a 20 MHz maximum clock speed. It is supplied in a 28-SSOP surface-mount package and is rated for the industrial -40 °C to +85 °C temperature range. According to the Microchip PIC16C63A/65B/73B/74B family datasheet, it is one-time programmable and supports 35 single-word instructions with a 200 ns instruction cycle.
What is the difference between OTP and flash versions of this MCU?
The PIC16C63AT-20I/SS uses one-time-programmable (OTP) memory that can be programmed only once in production. Flash-based equivalents such as the PIC16F873A-I/SS offer in-circuit reprogrammability, which is preferred for prototypes and field firmware updates. For production runs where the firmware is locked at the factory and BOM cost is critical, the OTP variant is usually the lower-cost choice.
What is the operating voltage of PIC16C63AT-20I/SS?
The PIC16C63AT-20I/SS operates from a 4.0 V to 5.5 V supply. This 5 V-typical range matches the PIC16C63A family specification from Microchip. Designs must stay within this window; operation below 4.0 V risks brown-out on brown-out-reset-enabled configurations, while operation above 5.5 V violates the absolute-maximum specification.
How many I/O pins does PIC16C63AT-20I/SS have?
The PIC16C63AT-20I/SS provides 22 digital I/O pins across PORTA, PORTB, and PORTC. According to the Microchip datasheet, these pins multiplex with peripheral functions such as A/D converter inputs, USART lines, and the synchronous serial port, so the number of pure GPIO pins available in any given design depends on which peripherals are enabled.
Is PIC16C63AT-20I/SS the same as PIC16C63A-20I/SS?
Yes, they are essentially the same die with different suffix codes. The 'T' suffix denotes tape-and-reel packaging, so PIC16C63AT-20I/SS is the tape-and-reel version of PIC16C63A-20I/SS. Both share the 28-SSOP industrial-temperature profile, 7 KB OTP, 192 B RAM, and 20 MHz clock; the MPNs are drop-in equivalent on a populated board.
Where can I download the PIC16C63AT-20I/SS datasheet PDF?
The official PIC16C63AT-20I/SS datasheet is published by Microchip as part of the PIC16C63A/65B/73B/74B family datasheet, accessible via the Microchip website or distributor portals. According to verified sources, the document is hosted at https://ww1.microchip.com/downloads/en/devicedoc/30261c.pdf; always check the latest revision letter before designing.
What is the difference between PIC16C63AT-20I/SS and PIC16C63-20I/SO?
Both PIC16C63AT-20I/SS and PIC16C63-20I/SO are from the same PIC16C6x family, but they differ in memory size and package. The PIC16C63 has 4 KB program memory versus 7 KB on the PIC16C63A, and the /SS suffix denotes a 28-SSOP package while /SO denotes a 28-SOIC package. Neither is pin-compatible with the other for board-level drop-in replacement because of the package difference.
Can PIC16F648A-I/SS replace PIC16C63AT-20I/SS directly?
Yes, the PIC16F648A-I/SS is often used as a flash-based functional replacement for the PIC16C63AT-20I/SS. Both come in 28-SSOP industrial-temperature packages, and the PIC16F648A adds flash memory for development convenience. According to the PIC16F648A datasheet, code written for the PIC16C63A family ports easily because the core architecture and most peripherals are compatible, though designers should verify the specific peripheral map before production.
Where to buy PIC16C63AT-20I/SS online at the best price?
PIC16C63AT-20I/SS is available from major distributors including DigiKey, Mouser, LCSC, and Heisener. As of 2026-09-17, listed distributor pricing is approximately $4.50 at qty-1 (Heisener: $4.4951) and as low as $1.85 at LCSC. Stock fluctuates on this legacy part; for high-volume pricing, request a quote directly from Microchip or authorized distributors.
What is the lead time for PIC16C63AT-20I/SS?
Lead time for PIC16C63AT-20I/SS is typically 3-7 days at distributors such as Heisener (estimated delivery Sep 3-Sep 8) for in-stock quantities, but for very large orders lead time can extend to several weeks because this is a mature-family OTP part. As of 2026-09-17, Heisener reports in stock; LCSC also lists in-stock inventory. Contact Microchip direct for production-volume schedules.
Is PIC16C63AT-20I/SS still in production?
Yes. The PIC16C63AT-20I/SS is currently listed as ACTIVE in the Microchip product life cycle database. Although OTP mid-range parts are mature, Microchip continues to support industrial customers that require long-life-cycle supply. For new designs, however, Microchip typically recommends the flash-based PIC16F or PIC18 families for greater flexibility.
What package does PIC16C63AT-20I/SS use and what is the footprint?
The PIC16C63AT-20I/SS uses the 28-pin SSOP (Shrink Small Outline Package) with a 0.209" (5.30 mm) body width and 0.65 mm pitch. This SSOP-28 footprint is shared with the PIC16F873A-I/SS, PIC16F648A-I/SS, and other PIC16C/16F family SSOP-28 parts, which makes PCB layout reuse across the family straightforward.
Is PIC16C63AT-20I/SS RoHS compliant?
The 'SS' suffix indicates lead-free / RoHS-compliant SSOP packaging per Microchip ordering code conventions. For EU shipment and consumer products, RoHS is required; the industrial-grade /SS variant meets this requirement. Check the latest manufacturer declaration of conformity before release, particularly for medical or automotive end products.
What is the pinout of PIC16C63AT-20I/SS?
The PIC16C63AT-20I/SS uses the standard 28-SSOP PIC mid-range pinout: pin 1 is /MCLR/Vpp, pins 2-7 are RA0-RA5, pin 8 is Vss, pins 9-10 are OSC1/OSC2, pin 11 is RC0, pin 12 is RC1, pin 13 is RC2, pin 14 is RC3/SCL, pin 15 is RC4/SDA, pin 16 is RC5/SDO, pin 17 is RC6/TX/CK, pin 18 is RC7/RX/DT, pin 19 is Vss, pin 20 is Vdd, pins 21-28 are RB0-RB7. Always verify against the official Microchip datasheet before PCB layout.
What is the maximum operating temperature of PIC16C63AT-20I/SS?
The 'I' temperature grade in PIC16C63AT-20I/SS designates the industrial operating range of -40 °C to +85 °C. This range covers most indoor, factory, and outdoor-sheltered embedded applications but excludes automotive under-hood (-40 °C to +125 °C) and military (-55 °C to +125 °C) environments, which would need different ordering code suffixes.

선택 가이드

Choose PIC16C63AT-20I/SS when your design needs a 5 V, 20 MHz, 8-bit RISC OTP microcontroller in the SSOP-28 industrial-temperature package and firmware is locked at production programming. Choose PIC16F873A-I/SS if you need in-circuit reprogrammability during prototyping (flash memory, same SSOP-28 footprint). Choose PIC16F648A-I/SS as a flash alternative with the same 7 KB program memory but adding 64 B more RAM. Choose PIC16C73B-20I/SS if you need the same family plus enhanced A/D subsystem. Choose PIC16C65B-20I/SS only when you need 33 I/O pins rather than 22 - otherwise the smaller PIC16C63AT is more cost-effective.

  • Established mid-range architecture with 35-instruction RISC core (vs PIC16F648A-I/SS)

설계 노트

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.
