Description

The 651154F is the small-scale control application versions of Sanyo's 651154F of 4-bit single-chip CMOS microcontrollers, and feature the same basic architecture and instruction set. These microcontrollers include an 8- input 8-bit A/D converter and are appropriate for use in a wide range of applications, from applications with a small number of circuits and controls that were previously implemented in standard logic to applications with a larger scale such as home appliances, automotive equipment, communications equipment, office equipment, and audio equipment such as decks and players. Also note that since these ICs provide the same basic functions (certain functions and specifications do differ) as, and are pin compatible with the earlier 651154F, they can replace those ICs in most cases.
