Abstract: This paper introduces a programmable system-chip PSoC (Programmable
System On-Chip), including its key function, logical structure and system
implementation. Analyzing its basic axiom of voltage to frequency converter,
demonstrating a new method to build V/F converter using one continuous time PSoC
block and Analog/Digital mixed signal array block based on traditional V/F
converter. Compared to traditional technique, advantages are obvious, such as
simplify external circuit, low cost, high precision, low power consumption, good
reliability. And it also makes function integrating more easier.
