Designed specifically to address high-end embedded
applications, the PowerPC 440GX (PPC440GX) pro-
vides a high-performance, low power solution that
interfaces to a wide range of peripherals by incorporat-
ing on-chip power management features and lower
power dissipation.
This chip contains a high-performance RISC processor
core, DDR SDRAM controller,8KB SRAM, PCI-X bus
interface, Ethernet interfaces, control for external ROM
and peripherals, DMA with scatter-gather support, serial
ports, IIC interface, and general purpose I/O.

Packages: 25 mm, 552-ball Ceramic Ball Grid Array
(CBGA) or Plastic Ball Grid Array (PBGA)
Power (estimated): Less than:
4.0W in normal mode
1.0 W in sleep mode
Supply voltages required: 3.3V, 2.5V, 1.8V
