CY8C27x43 Silicon B – These parts are lead free and offer the following improvements. The DEC_CR1 register selections are enhanced to allow any digital block to be
the decimator clock source, the ECO EX and ECO EXW bits in the CPU_SCR1 register are readable, and the accuracy of the analog reference is enhanced (see the
Electrical Specifications chapter). All silicon A errata are fixed in silicon B.
