1. GENERAL DESCRIPTION
The TMPR4925XB, to be referred as TX4925 MIPS RISC micro-controller is a highly
integrated ASSP solution based on Toshiba’s TX49/H2 processor core, a 64-bit MIPS I,II,III
ISA Instruction Set Architecture (ISA) compatible with additional instructions. The TX4925
is a highly integrated device with integrated peripherals such as SDRAM memory controller,
NAND Flash memory controller, PCI controller, AC-Link controller, PIO, SIO, SPI, CHI,
PCMCIA I/F and Timer. This class of product is targeted for applications that require a high
performance and cost-effective solution such as networking, digital consumer and Internet
appliance.
