TMPR3927F
(32-bit RISC MICROPROCESSOR)
1. GENERAL DESCRIPTION
The TMPR3927F (to be called “TX3927” hereinafter) is a standard micro controller of the 32-bit
RISC Microprocessor TX39 family. The TX3927 uses the TX39/H2 processor core as the CPU.
The TX39/H2 processor core is a RISC CPU core Toshiba developed based on the R3000A
architecture of MIPS Technologies, Inc. The TX3927 has built-in peripheral circuits which include
memory controllers, a PCI controller, DMA controller, serial and parallel ports, and timer/counters.
