440EP – PPC440EP Embedded Processor
Data Sheet
Revision 1.26 – April 25, 2007
Power Sequencing
Startup sequencing of the power supply voltages is not required. However, a power-down cycle must complete
(OVDD and VDD are below +0.4V) before a new power-up cycle is started.

Notes:
1. Typical Power is based on nominal voltage of VDD = +1.5V and TC = max. specified in Table 8 on page 59, while running Linux and a test
application that exercises each core with representative traffic.
