TMPR3904AF
(32 bit TX System RISC)
1. GENERAL DESCRIPTION
The TMPR3904AF (to be called TX3904A hereinafter) is a standard micro controller of the 32-
bit RISC Microprocessor TX39 family. The TX3904A uses the TX39 Processor Core as the CPU.
The TX39 Processor Core is a RISC CPU core Toshiba developed based on the R3000A
architecture of MIPS Technologies, Inc. As micro-controllers that can be embedded, besides the
TX39 Processor Core, the TX3904A has built-in peripheral circuits such as memory controllers,
DMA controllers, serial ports, and timers/counters.
