PIC16C63AT-04E/SO 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, data RAM, and peripheral interfaces. The PIC16C family is built on Microchip's RISC-based 8-bit Harvard architecture, where program and data buses are physically separated to allow simultaneous fetch and read, enabling single-cycle instruction execution under steady-state pipeline operation. The PIC16C63A/65B/73B/74B sub-family is the mid-range tier that added enhanced peripherals such as the USART, MSSP (SPI/I2C), and capture/compare/PWM modules beyond the baseline PIC16C5X family.
Key features of the PIC16C63AT-04E/SO include 4 MHz maximum operating frequency, 7 KB (4K x 14) OTP EPROM program memory, 192 bytes of RAM, two 8-bit timers plus one 16-bit timer/counter, a 10-bit multi-channel ADC, an enhanced USART for serial communications, a Master SSP supporting SPI and I2C, and a programmable brown-out reset. The 'A' suffix denotes the silicon revision; 'T' denotes tape-and-reel packaging; '04' denotes the 4 MHz speed grade; 'E' denotes the extended automotive temperature grade; and 'SO' denotes the 28-pin wide-body small-outline IC package.
Typical applications for this MCU include industrial control subsystems, automotive body electronics, sensor interface modules, and legacy embedded designs where OTP memory is acceptable and the long-life-cycle automotive-grade qualification is required. Because the program memory is OTP, firmware is committed during production programming and cannot be re-programmed in-circuit, which suits high-volume fixed-function controllers.
When designing with this part, ensure the in-circuit emulator (ICE) or production programmer is compatible with the PIC16C63A family and that the brown-out reset voltage threshold is configured above the minimum Vdd. The 28-SOIC wide-body package has a thermal resistance typically around 50-70 C/W (junction-to-ambient), so no heatsink is required at the modest 5V/4 MHz operating point. The MCU is well-suited for drop-in upgrades within the same PIC16C63A family when speed grade, temperature grade, and package are matched.

主な用途
PIC16C63AT-04E/SO の用途: 6 件s: Automotive Body Electronics, Industrial Control Subsystems, Sensor Interface Module, Consumer Appliance Control, Building Automation Nodes, Security and Access Control Panels.
Automotive Body Electronics
The PIC16C63AT-04E/SO's extended automotive temperature grade (-40 C to +125 C) and OTP memory make it well-suited for body-electronic modules such as seat controllers, mirror adjusters, interior lighting drivers, and accessory control units. The 22 digital I/O pins are sufficient to drive relays, read switches, and communicate with a vehicle CAN/LIN gateway via the enhanced USART or MSSP. The OTP-EPROM memory locks firmware at production programming, preventing field-reprogramming that could affect automotive functional-safety integrity. At 4 MHz with a 2.5-5.5V Vdd, the device pairs naturally with 5V sensor and actuator rails. Automotive E-grade qualification also provides the long-term reliability needed for 10-15 year vehicle service life.
おすすめ
Industrial Control Subsystems
In industrial control panels, the PIC16C63AT-04E/SO is well-matched to fixed-function control loops such as motor starters, conveyor sequencers, and pump controllers. The 7 KB OTP-EPROM holds ladder-logic-style state machines and pre-computed control tables, while the 192-byte RAM keeps current state and lookup pointers. The 10-bit ADC (in this family) plus the MSSP allow direct connection to 4-20 mA sensor conditioning boards and I2C-based EEPROM for parameter storage. The automotive E-grade also covers industrial -40 C to +125 C environments, making the part acceptable for outdoor enclosures, machine tool cabinets, and process-control skids where temperatures swing widely. Brown-out reset and watchdog operation support unattended field installations.
おすすめ
Sensor Interface Module
The PIC16C63AT-04E/SO is a natural fit for dedicated sensor-interface modules that digitize analog signals and forward results over UART or SPI. Its multi-channel 10-bit ADC, combined with 192 bytes of RAM for sample buffers, supports multi-sensor polling at modest rates. The MSSP block provides I2C communication to digital sensors, while the enhanced USART offers RS-232/RS-485 forwarding to a host controller. Operating at 4 MHz (1 MIPS), the part can service 4-8 sensors at sub-kHz sample rates with software FIR filtering. The 28-SOIC wide-body package is also easy to hand-solder for low-volume custom instrumentation.
おすすめ
Consumer Appliance Control
Household appliances such as washing machines, dishwashers, and HVAC indoor units benefit from the PIC16C63AT-04E/SO's cost-effective OTP memory and USART/MSSP peripherals. The 7 KB program memory stores the cycle logic, user-interface state machine, and fault-diagnostic table, while the timers drive PWM-controlled motor and valve outputs. The 22 I/O pins handle keypad scanning, LCD or LED display multiplexing, and triac/relay drive. The automotive E-grade covers under-cabinet and attic thermal environments, where appliance electronics can see 70-85 C. OTP programming at production locks the firmware and helps protect the design from unauthorized copying.
おすすめ
Building Automation Nodes
Distributed building-automation nodes - lighting controllers, blind actuators, and HVAC zone dampers - are well-served by the PIC16C63AT-04E/SO. Each node runs a fixed control algorithm in OTP memory, with 192 bytes of RAM holding current setpoint, schedule, and override state. The MSSP drives I2C sensors (temperature, humidity, light) and the USART provides optional Modbus or BACnet MS/TP connectivity over RS-485 transceivers. The wide 2.5-5.5V supply range simplifies integration with 24V building-control rails via small LDOs. The automotive temperature grade covers rooftop equipment rooms and unconditioned electrical closets.
おすすめ
Security and Access Control Panels
Fixed-function security panels for door controllers, alarm keypads, and motion-detector aggregators can use the PIC16C63AT-04E/SO as a low-cost, deterministic controller. Its 22 I/O pins handle keypad scanning, LED indicators, buzzer drivers, and a Wiegand or clock-data interface to card readers via the USART. The MSSP can host I2C EEPROMS for credential and event-log storage. The brown-out reset and watchdog timer contribute to the fail-safe behavior required in security applications. The OTP memory locks the firmware at production, hardening the device against code-removal attacks.

設計ノート
The PIC16C63AT-04E/SO operates from 2.5 V to 5.5 V; at the nominal 5 V supply the typical IDD is around 2-5 mA at 4 MHz, and standby (sleep) current falls below 1 uA. Decouple Vdd with a 100 nF ceramic capacitor placed within 5 mm of the Vdd pin (pin 11), and add a bulk 10 uF tantalum or aluminum if the rail is shared with inductive loads. Brown-out reset should be configured so that its threshold sits above the minimum Vdd at which the program memory retains data, typically around 4.0-4.3 V for the 5 V grade.
Place the 4 MHz crystal or resonator as close as possible to OSC1 (pin 13) and OSC2 (pin 14), with short traces and a ground guard ring to minimize EMI. The 28-SOIC wide-body package gives good thermal dissipation (theta_JA around 50-70 C/W) so no heatsink is needed at the modest 5 V/4 MHz operating point. Keep digital switching traces away from analog AN0-AN7 inputs and the VREF pin (RA3) to preserve ADC accuracy. MCLR/VPP (pin 1) should be pulled up to Vdd through a 10 kohm resistor and decoupled with a 100 nF cap to ground for noise-free reset.
Because the PIC16C63AT-04E/SO uses OTP EPROM, the firmware is committed at production programming and CANNOT be re-programmed in-circuit. Do not use this part for prototyping or any design that needs in-field firmware updates - choose a PIC16F-series flash MCU for those applications. Also, the silicon-revision 'A' parts (PIC16C63A) have an enhanced USART and MSSP that the original PIC16C63 (pre-A) parts lack; migrating code written for the pre-A revision to the A may require register-map updates. Estimate: at 4 MHz oscillator, 1 MIPS instruction throughput limits arithmetic loops; if higher throughput is required, use a 20 MHz PIC16C63A-20E variant.
