Notes:
1. If OVDD 0.4V, it is required that VDD 0.4V. Supply excursions not meeting this criteria must be limited to less than 25ms duration during each power up or power down event.
2. The analog voltages used for the on-chip PLLs can be derived from the logic voltage, but must be filtered before entering the PPC440GR. A separate filter, as shown below, is recommended for each voltage:
3. 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 440GR (PPC440GR) provides a high-performance, low- power solution that interfaces to a wide range of peripherals and incorporates on-chip power management features.
This chip PPC440GR contains a high-performance RISC processor, 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, NAND Flash interface, and general purpose I/O.
Technology: CMOS Cu-11, 0.13m.
Package: 35mm, 456-ball enhanced plastic ball grid array (E-PBGA).
Typical power (estimated): Less than 2.5W at 533MHz, 2.3W at 400MHz.
Supply voltages required: 3.3V, 2.5V, 1.5V.
