TMPR4938XB–300/333 (TX4938)

64-bit RISC Processor

Description

The TX4938 MIPS RISC microprocessor

is a highly integrated ASSP solution

based on the Toshiba TX49/H3

processor core, a 64-bit MIPS I, II, III

Instruction Set Architecture (ISA)

compatible with additional instructions.

The TX4938 has as peripheral functions

an external bus controller, an SDRAM

controller, a NAND flash controller, a PCI

controller, a DMA controller, an interrupt

controller, an AC-link controller, serial

and parallel ports, a timer/counter and

peripheral circuits such as Ethernet

MAC.

Features

• TX49/H3 core (on-chip IEEE754

• SDRAM controller

• NAND flash memory controller
