20.2.2 AC Characteristics
The AC characteristics of the H8/534 and H8/536 are listed in three tables. Bus timing parameters
are given in table 20-8, control signal timing parameters in table 20-9, and timing parameters of
the on-chip supporting modules in table 20-10.
Table 20-8 (1) Bus Timing (R-Mask Versions)
Condition A (R-mask):
VCC = 5.0 V ±10%, ø = 0.5 to 10 MHz, VSS = 0 V
Ta = –20 to +75˚C (Regular Specifications)
Ta = –40 to +85˚C (Wide-Range Specifications)
