The processor controller PIC16LC65A-04/PQ is a low cost, high performance, CMOS, fully static, processor controller PIC16LC65A-04/PQ 8-bit microcontroller family. All processor controller PIC16LC65A-04/PQ microcontrollers have adopted an advanced RISC architecture. The processor controller PIC16LC65A-04/PQ microcontroller family has enhanced core functionality, an 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 and a separate 8-bit wide data. A two-stage instruction pipeline allows all instructions to be executed in one cycle, with the exception of program branches, which require two cycles. A total of 35 instructions (simplified instruction set) are available. In addition, the large register set provides some architectural innovations for high performance. Processor Controller PIC16LC65A-04/PQ microcontrollers typically achieve 2:1 code compression and 4:1 speed improvement over other 8-bit microcontrollers in their class. The processor controller PIC16LC65A-04/PQ device has 36 bytes of RAM and 13 I/O pins. Also, there are timers/counters. PIC16C62/62A/R62 devices have 128 bytes of RAM and 22 I/O pins. Additionally, some peripheral functions are available, including: three timers/counters, a capture/compare/PWM module and a serial port. The synchronous serial port can be configured as a three-wire Serial Peripheral Interface (SPI) or a two-wire Inter-Integrated Circuit (I2C). PIC16C63/R63 devices have 192 bytes of RAM, while PIC16C66 has 368 bytes. All three devices have 22 I/O pins. Additionally, some peripheral functions are available including: three timers/counters, two capture/compare/PWM modules and two serial ports. The synchronous serial port can be configured as a three-wire Serial Peripheral Interface (SPI) or a two-wire Inter-Integrated Circuit (I2C). Universal Synchronous Asynchronous Receiver Transmitter (USART) is also known as Serial Communication Interface or SCI. PIC16C64/64A/R64 devices have 128 bytes of RAM and 33 I/O pins. Additionally, some peripheral functions are available, including: three timers/counters, a capture/compare/PWM module and a serial port. The synchronous serial port can be configured as a three-wire Serial Peripheral Interface (SPI) or a two-wire Inter-Integrated Circuit (I2C). An 8-bit parallel slave port is also provided. PIC16C65/65A/R65 devices have 192 bytes of RAM, while PIC16C67 has 368 bytes. All four devices have 33 I/O pins. Additionally, some peripheral functions are available including: three timers/counters, two capture/compare/PWM modules and two serial ports. The synchronous serial port can be configured as a three-wire Serial Peripheral Interface (SPI) or a two-wire Inter-Integrated Circuit (I2C). Universal Synchronous Asynchronous Receiver Transmit

ter (USART) is also known as Serial Communication Interface or SCI. An 8-bit parallel slave port is also provided. The PIC16C6X family of devices features fewer external components, resulting in lower cost, higher system reliability, and lower power consumption.
