Power Consumption Under Recommended Operating Conditions
TABLE 13-4. Power Consumption
13.2 DC CHARACTERISTICS OF PINS, BY GROUP
The following tables list the DC characteristics of all device pins described in Section 1.2. The pin list preceeding each table
lists the device pins to which the table applies.
13.2.1
Group 1
Pin List:
A15-0, AEN, ASTRXB, CTS2,1, DACK3-0, DCD2,1, DSKCHG, DSR2,1, ID3-0, INDEX, IRRX2,1, MR, RD, RDATA,
SIN2,1, TC, TRK0, WP, WR, XDRD
TABLE 13-5. DC Characteristics of Group 1 Pins
a. Do not permit VCCH to ramp down at a rate exceeding 1 V/msec. If it does, it may reset the Valid RAM and Time
(VRT) bit (bit 7) of the RTC Control Register D (CRD) at offset 0Dh of logical device 2.
a. Not tested. Guaranteed by design.
