TSPC603R
2125A–12/01
Table 11 provides the input AC timing specifications for the 603r as defined in Figure 6 and
Figure 7.
Notes:
1. All input specifications are measured from the TTL level (0.8 or 2.0V) of the signal in question to the 1.4V of the rising edge
of the input SYSCLK. Both input and output timings are measured at the pin. See Figure 7.
2. Address/data/transfer attribute input signals are composed of the following: A[0-31], AP[0-3], TT[0-4], TC[0-1], TBST,
TSIZ[0-2], GBL, DH[0-31], DL[0-31], DP[9-7].
3. All other input signals are composed of the following: TS, ABB, DBB, ARTRY, BG, AACK, DBG, DBWO, TA, DRTRY, TEA,
DBDIS, HRESET, SRESET, INT, SMI, MCP, TBEN, QACK, TLBISYNC.
4. The setup and hold time is with respect to the rising edge of HRESET. See Figure 7.
5. t
sysclk
is the period of the external clock (SYSCLK) in nanoseconds (ns). The numbers given in the table must be multiplied
by the period of SYSCLK to compute the actual time duration (in nanoseconds) of the parameter in question.
6. These values are guaranteed by design, and are not tested.
7. This specification is for configuration mode only. Also note that HRESET must be held asserted for a minimum of 255 bus
clocks after the PLL relock time (100 μs) during the power-on reset sequence.
