The AT8PU86MF has program memory size greater 2K works, but the CALL and GOTO instructions only have a
11-bits address range. This 11-bit address range allows a branch within a 2K program memory page size. To allow
CALL and GOTO instructions to address the entire 6K program memory address range for AT8PU86, there is
another two bits to specify the program memory page.
The AT8E68B series is a family of low-cost, high speed, high noise immunity, EPROM/ROM-based 8-bit CMOS
microcontrollers. It employs a RISC architecture with only 49 instructions. All instructions are single cycle except
for program branches which take two cycles. The easy to use and easy to remember instruction set reduces
development time significantly.
The AT8P32F is a low-cost, high speed, high noise immunity, FLASH-based 8-bit CMOS microcontrollers. It
employs a RISC architecture with only 41 instructions. All instructions are single cycle except for program branches
which take two cycles. The easy to use and easy to remember instruction set reduces development time
significantly.
