July 25, 2011 PCN Number: 1111 PCN Change Level: Major Subject: RT ProASIC3 Datasheet Updates Dear Customer, Microsemi has updated the Radiation-Tolerant ProASIC®3 Low Power Spaceflight Flash FPGAs datasheet from Advance to Production status. The latest revision can be downloaded here: http://www.actel.com/documents/RTPA3_DS.pdf. Some of the major updates in this revision are listed below. 1. Device status: RT3PE600L and RT3PE3000L have moved to Production status with completed characterization on DC, timing, and power characteristics. 2. Radiation performance: Total ionizing dose (TID) improved from 15 Krad to the following: 3. • 25 to 30 Krad with 10% propagation delay increase, dose rate 5 Krad/min • Up to 40 Krad with 10% propagation delay increase, dose rate < 1 Krad/min • Up to 55 Krad with 15% propagation delay increase, dose rate < 1 Krad/min I/O DC output levels: • VOL and VOH for all I/O standards have been updated for operating in the following junction temperature (TJ) ranges: –55°C < TJ ≤ 100°C and 100°C < TJ ≤ 125°C • 4. 5. Drive strength for 3.3 V GTL and 2.5 V GTL I/O standards have been updated from 25 mA to 20 mA. Quiescent supply current in different operating modes has been updated in Tables 2-6, 2-7, 2-8, 2-9, and 2-10. Support for wide range core voltage was added; 3.3 V LVCMOS wide range and 1.2 V LVCMOS wide range I/O standards were added. A wide range operating core voltage VCCA can be selected for operation at any point in the nominal range of 1.2 V to 1.5 V, providing system designers flexibility for power supply options such as dual voltage, dynamic voltage/frequency scaling, and unregulated battery applications.
