PIC16C622A-04/P

The PIC16C62X devices are 18 and 20-Pin ROM/
EPROM-based members of the versatile PICmicro?
family of low cost, high performance, CMOS, fullystatic, 8-bit microcontrollers.
All PICmicro microcontrollers employ an advanced
RISC architecture. The PIC16C62X devices 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.
