604 Hardware Specifications

3

Preliminary/Subject to Change without Notice

Table 3 provides the DC electrical characteristics for the 604.

Table 4 provides the power dissipation numbers for the 604.

1.3 AC Electrical Characteristics

This section provides the AC electrical characteristics for the 604. These specifications are for parts that

operate at processor core frequencies of 100, 120, and 133 MHz. The processor core frequency is

determined by the bus (SYSCLK) frequency and the settings of the PLL_CFG0–PLL_CFG3 pins. All

timings are specified respective to the SYSCLK.

Notes:

1. Power measured does not include power dissipated in output drivers.

2. Typical power is an average value measured at 3.3 V in a system executing typical

applications and benchmark sequences. Typical power numbers should be used in planning

for proper thermal management.

3. Maximum power is measured at 3.3 V using a worst case instruction mix. These values should

be used for power supply design.
