Description
The PIC16CXX is a family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers. All PIC16/17 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 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. PIC16CXX microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers in their class. The PIC16C61 device has 36 bytes of RAM and 13 I/O pins. In addition a timer/counter is available. The PIC16C62/62A/R62 devices have 128 bytes of RAM and 22 I/O pins. In addition, several peripheral features are available, including: three timer/counters, one Capture/Compare/PWM module and one serial port. The Synchronous Serial Port can be configured as either a 3-wire Serial Peripheral Interface (SPI?) or the two-wire Inter-Integrated Circuit (I2C) bus. The PIC16C63/R63 devices have 192 bytes of RAM, while the PIC16C66 has 368 bytes. All three devices have 22 I/O pins. In addition, several peripheral features are available, including: three timer/counters, two Capture/Compare/PWM modules and two serial ports. The Synchronous Serial Port 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 know as a Serial Communications Interface or SCI. The PIC16C64/64A/R64 devices have 128 bytes of RAM and 33 I/O pins. In addition, several peripheral features are available, including: three timer/counters, one Capture/Compare/PWM module and one serial port. The Synchronous Serial Port can be configured as either a 3-wire Serial Peripheral Interface (SPI) or the two-wire Inter-Integrated Circuit (I2C) bus. An 8-bit Parallel Slave Port is also provided. The PIC16C65/65A/R65 devices have 192 bytes of RAM, while the PIC16C67 has 368 bytes. All four devices have 33 I/O pins. In addition, several peripheral features are available, including: three timer/counters, two Capture/Compare/PWM modules and two serial ports. The Synchronous Serial Port 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 a Serial Communications Interface or SCI. An 8-bit Parallel Slave Port is also provided. The PIC16C6X device family has 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) mode offers a power saving mode. The user can wake the chip from SLEEP through several external and internal interrupts, and resets. A highly reliable Watchdog Timer with its own on-chip RC oscillator provides protection against software lockup. A UV erasable CERDIP packaged version is ideal for code development, while the cost-effective One-Time-Programmable (OTP) version is suitable for production in any volume.
