Preliminary Information

Power Derating Based on Lower CPU Frequencies

This section provides standard- and low-power product

specification power derating based on lower CPU frequencies.

Note: The 166-MHz and 200-MHz data provided in Table 54 and

Table 55 was derived from the standard- and low-power

AMD-K6-2E/233AFR (and AMZ) and AMD-K6-2E/266AFR

(and AMZ) products and is solely for informational

purposes.

The

guaranteed

electrical

and

thermal

specification data for the AMD-K6-2E/233AFR (and AMZ)

and AMD-K6-2E/266AFR (and AMZ) is also included here

for convenience. The derating data may be of interest to

customers who want to use AMD’s standard- or low-power

devices at lower CPU frequencies. AMD does not guarantee

the 166-MHz and 200-MHz CPU frequency derating data

and does not provide devices with these lower CPU

frequencies. Only devices listed in Table 73, “Valid Ordering

Part Number Combinations,” on page 306 are available.

Maximum ICC2 (core)

VCC2 = 2.2 V ± 100 mV

2. The maximum ICC2 specification is taken at VCC2 = 2.3 V. (The maximum power supply current must be taken into account when

designing a power supply.)

7.35 A

Maximum ICC3 (I/O)

VCC3 = 3.3 V +300 mV, –165 mV

3. The maximum ICC3 specification is taken at VCC3 = 3.6 V. (The maximum power supply current must be taken into account when

designing a power supply.)

Thermal Power (Maximum)4

4. Maximum thermal power is determined for the worst-case instruction sequence or functions for the listed clock control states

with VCC2 = 2.2 V and VCC3 = 3.3 V.

Thermal Power (Typical)5

5. Typical thermal power is determined for the typical instruction sequence or functions associated with normal system operation

with VCC2 = 2.2 V and VCC3 = 3.3 V.
