PIC16F62X FLASH-Based 8-Bit CMOS Microcontroller

GENERAL DESCRIPTION
The PIC16F62X are 18-Pin FLASH-based members of the versatile PIC16CXX family of low cost, high performance, CMOS, fully static, 8-bit microcontrollers. All PICmicro® microcontrollers employ an advanced RISC architecture. The PIC16F62X have 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. PIC16F62X microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers in their class. The PIC16F62X has eight oscillator configurations. The single pin ER oscillator provides a low cost solution. The LP oscillator minimizes power consumption, XT is a standard crystal, INTRC is a self-contained internal oscillator. The HS is for High Speed crystals. The EC mode is for an external clock source. The SLEEP (Power-down) mode offers power savings. The user can wake-up the chip from SLEEP through several external interrupts, internal interrupts, and RESETS. A highly reliable Watchdog Timer with its own on-chip RC oscillator provides protection against software lockup. The FLASH technology makes customization of application programs (detection levels, pulse generation, timers, etc.) extremely fast and convenient. The small footprint packages make this microcontroller series ideal for all applications with space limitations. Low cost, low power, high performance, ease of use and I/O flexibility make the PIC16F62X very versatile.
