January 25, 2013 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) Previous New –1 Std. –1 Std. 1,048 1,232 1,232 1,084 Table 2 • Output (FDDOMAX) Previous 2. New –2 Std. –2 Std. 1,048 1,404 1,404 1,048 Table 1 lists the affected Fusion parts. 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 Microsemi Corporation One Enterprise, Aliso Viejo CA 92656 USA Within the USA: +1 (949) 380-6100 · Sales: +1 (949) 380-6136 Fax: +1 (949) 215-4996 · www.microsemi.com Part No. 54400163-0 entire temperature range being monitored. Offset and gain are part of the temperature monitor's accuracy parameters; the gain is unchanged. If a design uses the temperature monitor, CalibIP within the SmartGen Analog System Builder must be used in order for the design to have a 0°C offset. Microsemi believes there is no impact if you are using CalibIP. Modified values for uncalibrated offset are given in Table 3. Table 3 • Uncalibrated and Calibrated offset Device Prefix Previous Uncalibrated Offset New Uncalibrated Offset Calibrated Offset 5°C 11°C 0°C AFS250 M1AFS250 P1AFS250 U1AFS250 Note: *When using SmartGen Analog System Builder, CalibIP is required to obtain a 0°C offset. For further details on CalibIP, refer to the “Temperature, Voltage, and Current Calibration in Fusion FPGAs” chapter of the Fusion FPGA Fabric User’s Guide. Table 2 lists the affected Fusion parts. 3. The datasheet has been updated with a recommendation for analog reference voltage (VAREF) circuitry. When connected to an external reference of 3.3 V, Microsemi recommends connecting the VAREF pin with a resistor of approximately 1 KOhm, to limit current, and placing a 10–100 nF capacitor between VAREF and GNDA. Table 1 lists the affected Fusion parts. These changes are reflected in Revision 4 of Microsemi’s Fusion Family of Mixed Signal FPGAs Datasheet: www.microsemi.com/soc/documents/Fusion_DS.pdf.
