(64-bit RISC MICROPROCESSOR)
1. GENERAL DESCRIPTION
The TMPR4927ATB, to be referred as TX4927 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 TX4927
is a highly integrated device with integrated peripherals such as SDRAM memory controller,
PCI controller, PIO, AC-Link, UART and Timer. This class of product is targeted for
applications that require a high performance and cost-effective solution such as networking
and printers.
2. FEATURES
