2.3.6.1 Plaintext Initialization Data Without Authentication

(Ask a Question)

The following formulas apply where there is at least one LSRAM or USRAM to be auto-initialized in the user design from SPI Flash, giving a duration in milliseconds.

tLSRAM_pt = [[{(ROUNDUP(4.034 ×L ) + 1) × 8192 / f} + (130 × L)] / 1000] + 1 ± 6%

tUSRAM_pt = [[{(ROUNDUP(0.144 × U) + 1) × 8192 / f} + (25 × U)] / 1000] + 1 ± 6%

Where,

L = Number of LSRAMs to be auto-initialized

U = Number of small SRAMs to be auto-initialized

f = Frequency of the SPI clock in MHz

Important: pt in "tLSRAM_pt" and "tUSRAM_pt" refers to "plaintext".
