DESCRIPTION
The STPC Elite integrates a fully static x86
processor up to 133 MHz, fully compatible with
standard x86 processors, and combines it with
powerful chipset to provide a general purpose PC
compatible subsystem on a single device. The
device is packaged in a 388 Ball Grid Array
(PBGA).
The STPC Elite has a low voltage operation with
V_CORE = 2.5V and has 5V tolerant I/Os (3.3V
output levels).
