The Versal Architecture and Product Data Sheet: Overview (DS950) lists the Versal AI Core devices that include the accelerator RAM (XRAM).

Table 1. Accelerator RAM Switching Characteristics
Symbol	Description	Performance as a Function of Speed Grade and Operating Voltage (V_{CC_PSLP})					Units
		0.88V (H)	0.80V (M)		0.80V (L)
		-2	-2	-1	-2	-1
F_{MAX_XRAM}	Maximum accelerator RAM (XRAM) clock frequency	800	625	600	500	450¹	MHz
F_{PL_XRAM}	Maximum accelerator RAM PL interface frequency	375	325	300	270	250²	MHz
The -1LLI and -1LSI low-power devices support an overdrive voltage where the maximum clock frequency is 800 MHz when V_{CC_PSLP} = 0.88V. The -1LLI and -1LSI low-power devices support an overdrive voltage where the maximum clock frequency is 350 MHz when V_{CC_PSLP} = 0.88V.
