PC8240
2149A–HIREL–05/02
9. The typical maximum GVdd value resulted from the PC8240 operating at the fastest frequency combination of 66:100:200
(PCI:Mem:CPU) MHz and performing continuous flushes of cache lines with alternating ones and zeroes on 64-bit bound-
aries to local memory.
To calculate the power consumption at low temperature (-55°C), use a 1.25 factor.
Note:
Marking
The document where markings are defined is identified in the related reference docu-
ments. Each microcircuit is legible and permanently marked with the following
information as minimum:
Atmel Logo,
Manufacturer’s part number,Date-code of inspection lot,
ESD identifier if available,
Country of manufacturing.

Static Characteristics
Table 6 provides the DC electrical characteristics for the PC8240.
At recommended operating conditions (see Table 3 on page 8)
Notes:
1. See Table 1 on page 3 for pins with internal pull-up resistors.
2. Capacitance is periodically sampled rather than 100% tested.
