The PIC16F84-04/P is a 8-bit 4MHz fully-static CMOS flash/EEPROM Microcontroller. All PICmicro? microcontroller employ an advanced RISC architecture. The PIC16F8X device has enhanced core features, 8-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 a separate 8-bit wide data bus. 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 is used to achieve a very high performance level. The PIC16F8X microcontroller typically achieves a 2:1 code compression and up to a 4:1 speed improvement (at 20MHz) over other 8-bit microcontrollers in their class. The PIC16F8X has up to 68 bytes of RAM, 64 bytes of data EEPROM memory and 13 I/O pins. A timer/counter is also available.
