Note: At 8 MHz, the times below depend as indicated on the clock cycle time.
t_RAH = 0.5 × t_CYC – 38 (ns)
t_CAC = 1.0 × t_CYC – 75 (ns)
t_RAC = 2.0 × t_CYC – 90 (ns)
t_CSR = 0.5 × t_CYC – 43 (ns)
t_RP = t_CRP = 1.0 × t_CYC – 40 (ns)
At 13 MHz, the times below depend as indicated on the clock cycle time.
