CY8C21x34 Final Data Sheet
PSoC Overview
Document Conventions
Acronyms Used
The following table lists the acronyms that are used in this doc-
ument.
Units of Measure
A units of measure table is located in the Electrical Specifica-
tions section.
Table 3-1 on page 15
lists all the abbreviations
used to measure the PSoC devices.
Numeric Naming
Hexidecimal numbers are represented with all letters in upper-
case with an appended lowercase ‘h’ (for example, ‘14h’ or
‘3Ah’). Hexidecimal numbers may also be represented by a ‘0x’
prefix, the C coding convention. Binary numbers have an
appended lowercase ‘b’ (e.g., 01010100b’ or ‘01000011b’).
Numbers not indicated by an ‘h’, ‘b’, or 0x are decimal.
