Description

The XPC850DEZT50B is a versatile one-chip integrated microprocessor and peripheral combination designed for a variety of controller applications. It excels in both communications and networking systems. The XPC850DEZT50B features an embedded single-issue, 32-bit MPC8xx core implementing the PowerPC architecture. It operates at up to 80 MHz and has a 32-bit data bus and 32 address lines. The XPC850DEZT50B also includes a memory controller, general-purpose timers, a system integration unit (SIU), baud-rate generators (BRGs), serial communications controllers (SCCs), serial management channels (SMCs), a serial peripheral interface (SPI), an I2C port, a time-slot assigner (TSA), a parallel interface port (PIP), a PCMCIA interface, low power support, and a debug interface. It operates at 3.3 V with 5-V TTL compatibility and comes in a 357-pin ball grid array (BGA) package.
