M67206F Datasheet | Atmel

Description .. 1. Limitation to the operating conditions inside a timing and data marginal configuration. Radiation Tolerant FIFOs Rising edge of READ from 0 ns up to 8 ns (typical) before the falling edge of WRITE when only one data is left to read. See Figure 1 for behavior description . Failure Mode: Empty flag glitch and following data shift out 2nd byte corruption occurs when the rising edge of the first "READ" for data shift out occurs before falling edge of the third "WRITE" for data shift in. Worst Case Range: between 0 ns and 11 ns Temperature = 125°C Voltage = 4.5V Characterization: -55°C / 5.5V: 6 ns 25°C / 5V: Workaround These FIFOs are functional outside of the above timing and data marginal configuration. The remended action is to avoid this particular configuration . Please contact Atmel for a case by case application conditions analysis. Figure 1.
