Description
The PIC16C63A device is low cost, high performance, CMOS, fully-static, 8-bit microcontrollers in the PIC16CXX mid-range family. All PICmicro microcontrollers employ an advanced RISC architecture. The PIC16CXX microcontroller family has enhanced core features, eight-level deep stack and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches, which require two cycles. A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set gives some of the architectural innovations used to achieve a very high performance. The PIC16C63A device have 22 I/O pins. Each device has 192 bytes of RAM. In addition, several peripheral features are available, including: three timer/ counters, two Capture/Compare/PWM modules, and two serial ports. The Synchronous Serial Port (SSP) can be configured as either a 3-wire Serial Peripheral Interface (SPI) or the two-wire Inter-Integrated Circuit (I2C) bus. The Universal Synchronous Asynchronous Receiver Transmitter (USART) is also known as the Serial Communications Interface or SCI. The 8-bit resolution is ideally suited for applications requiring low cost analog interface, e.g., thermostat control, pressure sensing, etc. The PIC16C63A device have special features to reduce external components, thus reducing cost, enhancing system reliability and reducing power consumption. There are four oscillator options, of which the single pin RC oscillator provides a low cost solution, the LP oscillator minimizes power consumption, XT is a standard crystal, and the HS is for high speed crystals. The SLEEP (power-down) feature provides a power-saving mode. The user can wake-up the chip from SLEEP through several external and internal interrupts and RESETS. A highly reliable Watchdog Timer (WDT), with its own on-chip RC oscillator, provides protection against software lockup, and also provides one way of waking the device from SLEEP. A UV erasable CERDIP packaged version is ideal for code development, while the cost effective One-TimeProgrammable (OTP) version is suitable for production in any volume. The PIC16C63A device fit nicely in many applications ranging from security and remote sensors to appliance control and automotive. The EPROM technology makes customization of application programs (transmitter codes, motor speeds, receiver frequencies, etc.) extremely fast and convenient. The small footprint packages make this microcontroller series perfect for all applications with space limitations. Low cost, low power, high performance, ease of use and I/O flexibility make the PIC16C63A device very versatile, even in areas where no microcontroller use has been considered before (e.g., timer functions, serial communication, capture and compare, PWM functions and coprocessor applications).
