Description
The PowerPC 405CR (PPC405CR) is a 32-bit RISC
embedded controller. High performance, peripheral
integration, and low cost make the device ideal for
wired communications, network printers, and other
computing applications.
This device is an easy upgrade for systems based on
PowerPC 403xx embedded processors, while provid-
ing a base for custom chip designs.
The controller is powered by a PPC405 embedded
core. This core tightly couples a 266 MHz CPU, MMU,
instruction and data caches, and debug logic. Fine-
tuning of the core reduces data transfer overhead,
minimizes pipeline stalls, and improves performance.
The PPC405CR employs the IBM CoreConnectbus
architecture. This architecture, as implemented on the
PPC405CR, consists of a 64-bit, 133-MHz Processor
Local Bus (PLB) and a 32-bit, 66-MHz On-Chip
Peripheral Bus (OPB). High-performance peripherals
attach to the PLB and less performance-critical periph-
erals attach to the OPB.
Technology: CMOS SA-12E 0.25 µm (0.18 µm Leff)
Package: 27mm, 316-ball enhanced plastic ball grid
array (E-PBGA)
Power (estimated): Typical 0.8 W, Maximum 2.0 W at
200 MHz.
