W74110

The W74110 is a single-chip CMOS 4-bit microcontroller(C) that operates on low voltage and very low current. There are also four interrupt sources and 4-level subroutine nesting for interrupt applications. Besides, it is a powerful microcontroller for remote controllers, multiple I/O products, keyboard controllers, speech synthesis LSI controllers and other products.

W74110 has some features as follows: (1)built-in 14-bit clock frequency divider circuit; (2)built-in 8-bit programmable down-count timer; (3)powerful instruction set which is 83 instruction sets; (4)direct and indirect addressing mode; (5)4-level subroutine nesting; (6)internal serial transmission port RT specified by software; (7)up to 4 s instruction cycle at 1 MHz operatring frequency; (8)all instructions are executed in one machine cycle except for indirect addressing mode; (9)built-in crystal or RC oscillator by pin option.
