32-bit RISC microprocessor: TMPR3912AU-92，TMPR3912XB-92
32-bit RISC microprocessor with peripheral functions for portable information equipment
The TMPR3912 is an application-specific standard product (ASSP) built around the TX39/H processor core and incorporating the peripheral functions required for personal digital assistants (PDAs) on a single chip. In addition, this microprocessor has an enhanced power management function, making it ideal for PDAs. Thus, the TMPR3912AU/XB helps you minimize the size, reduce the cost, and increase the functionality of your portable information terminal system.
