PCN Number: 1301
PCN Change Level: Major
Subject: Changes in maximum DDR frequency for input and output propagation delays,
temperature monitor accuracy for AFS250 and analog reference voltage
capacitor recommendations for the Fusion family
Dear Customer,
The following changes have been made in the Fusion Family of Mixed Signal FPGAs
datasheet:
1. Maximum DDR frequencies for input and output propagation delays for Microsemi’s
Fusion devices have been rectified due to an inadvertent error in the datasheet. All
Fusion devices are affected for speed grade –2, grade –1 and Std., for parameters
FDDRIMAX and FDDOMAX.
Modified values for FDDRIMAX and FDDOMAX are given in Table 1 and Table 2.
Table 1 • Input (FDDRIMAX)

Table 1 lists the affected Fusion parts.
2. Analog channel specifications for Microsemi's AFS250 devices have changed.
Microsemi made the change to improve analog channel yield to increase product
availability. The offset specifications for the external and internal temperature
monitors have been changed according to Table 3 on page 2. The offsets apply to the
