RC64574 Socket Compatibility to RC64474 & RC4640
The RC64574/575 is 100% pin compatible with the RC64474/475 with the supply voltage being the only difference. RC64474/475 requires a 3.3V
supply, while RC64574/575 requires a 2.5V supply.
To ensure socket compatibility between the RC64574/RC64474 and the RC4640 devices, several pin changes are required, as shown in the tables
below. Note: The RC64574/575 are 2.5V parts and as such all Vcc must be at the correct voltage for a given part.

JTAG32*
No Connect
JTAG32*
Yes
In 32-bit, this pin can be left uncon-
nected because of internal pull-down.
In 64-bit, this assumes that JTAG will
not be used. If using JTAG, this pin
must be at Vcc.
