Notes:
1. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the PPC440GX. A separate filter, as shown below, is recommended for each voltage:
2. This value is not a specification of the operational temperature range; it is a stress rating only.
DescriptionDesigned specifically to address high-end embedded applications, the PowerPC 440GX (PPC440GX) provides a high-performance, low power solution that interfaces to a wide range of peripherals by incorporating on-chip power management features and lower power dissipation.
This 440GX contains a high-performance RISC processor core, DDR SDRAM controller, configurable 256KB SRAM to be used as L2 cache or softwarecontrolled on-chip memory, PCI-X bus interface, Gigabit Ethernet interfaces, TCP/IP acceleration hardware, I2O messaging unit, control for external ROM and peripherals, DMA with scatter-gather support, serial ports, IIC interface, and general purpose I/O.
440GX Technology: CMOS Cu-11, 0.13m0.
440GX Packages: 25mm, 552-ball Ceramic Ball Grid Array (CBGA) or Plastic Ball Grid Array (PBGA) in standard or RoHS compliant versions.
440GX Power (estimated): Less than:
4W typical @533MHz
5W typical @667MHz
6W typical @800MHz (estimated)
Supply voltages required: 3.3V, 2.5V, 1.5V
