Description
Designed specifically to address high-end embedded
applications, the PowerPC 440EP (PPC440EP)
provides a high-performance, low- power solution that
interfaces to a wide range of peripherals and
incorporates on-chip power management features.
This chip contains a high-performance RISC
processor, a floating point unit, DDR SDRAM
controller, PCI bus interface, control for external ROM
and peripherals, DMA with scatter-gather support,
Ethernet ports, serial ports, IIC interfaces, SPI
interface, USB ports, NAND Flash interface, and
general purpose I/O.
Technology: CMOS Cu-11, 0.13μm.
Package: 35mm, 456-ball standard plastic ball grid
array (E-PBGA), with and without lead (RoHS
compliant).
Typical power (measured): Less than 3W at 533MHz,
2.5W at 400MHz.
Supply voltages required: 3.3V, 2.5V, 1.5V.
