Timing was designed for a system load between 5pF and 60pF for low drive setting at typically no more than a 33MHz
clock
Timing was designed for a system load between 5pF and 50pF for medium drive setting at typically no more than a
66MHz clock
Timing was designed for a system load between 5pF and 40pF for high drive setting at typically no more than a 80MHz
clock
Drive settings do not apply to EX_CS_N signals and are expected to be point to point. The timing on this signal was
designed for a system load between 5pF and 10pF
EX_control_signals output signals consist of EX_ALE, EX_ADDR, EX_CS_N, EX_GNT_REQ_N, EX_GNT_N, EX_RD_N,
EX_WR_N, EX_WAIT_N
EX_control_signals input signals consist of EX_ADDR, EX_CS_N, EX_SLAVE_CS_N, EX_REQ_GNT_N, EX_REQ_N,
EX_BURST, EX_RD_N, EX_WR_N
Valid rising edge of EX_CLK to valid signal on the
output.
Valid signal hold time after the rising edge of EX_CLK
Valid data signal on an input prior to the rising edge of
EX_CLK
Required hold time of a data input after the rising edge
of EX_CLK
Valid control/arbiter signal on an input prior to the
rising edge of EX_CLK
Required hold time of a control/arbiter input after the
rising edge of EX_CLK
