PPC405EZ

The PowerPC 405EZ embedded 32-bit RISC processor provides a low power, small footprint
system-on-a-chip solution for a wide range of high performance, cost-constrained embedded
applications.It is an easily programmable general-purpose 32-bit RISC embedded processor
that offers an ideal upgrade path for applications
currently using 8-bit, 16-bit, RISC, or DSP MCUs needing performance and connectivity
improvements.

Implemented in the scalable PowerPC Architecture, the PPC405EZ processor delivers up to
632 DMIPS while maintaining code compatibility with other PowerPC processors
for ease in migration and fast time-to-market. Unique features include an external bus
optimized for high performance, low power CellularRAMs, the Chameleon
Timer(c)/PWM, and an IEEE1588 PTP controller that is tightly coupled to the Ethernet port,
analog functions, and other on-chip functions to optimize performance and eliminate CPU
involvement in capturing, triggering and timestamping real-time events in devices deployed
across entire networks.

With speeds of up to 416 MHz, a flexible on-chip and off-chip memory architecture, a
unique combination of ADC, DAC, IEEE1588 Precision Timing Protocol (PTP) controller,
configurable Chameleon Timer©/PWM, and a diverse connectivity package, the PowerPC
405EZ embedded processor provides a low power and small footprint system-on-a-chip
solution for a wide range of high performance,
cost-constrained embedded applications.
