Description
Designed specifically to address high-end embedded
applications, the PowerPC 440EPx (PPC440EPx)
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, on-chip SRAM, a floating point unit,
DDR2/1 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, an optional security feature
(PPC440EPx-S), and general purpose I/O.
Technology: CMOS Cu-11, 0.13
