Product Brief

TMPR4938XB–300/ 333 (TX4938)

64-bit RISC Processor

Highlights

Description

• External bus controller (8 channels)

• 32-bit PCI controller (33 MHz/66 MHz)

The TX4938 MIPS RISC microprocessor

is a highly integrated ASSP solution

based on the Toshiba TX49/H3

• 32-bit/66 MHz PCIC

Rev 2.2 supports up to

4 PCI devices

• Direct memory access controller:

8 channels (4 channels are dedicated to

AC-link controller)

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.

• Serial I/O port (2 channels)

• NAND flash controller

with IPL (Initial Program

Loader)

• Parallel I/O port (maximum 16-bits)

• Synchronous serial interface

• Timer/counter (3 channels)

• 2 Ethernet MACs

• AC-link controller (AC97 interface)

• Ethernet MAC (2 channels)

• On-chip ROM for program loader

• On-chip SRAM (2 KB)

• High system

performance and low-

power consumption of

1.5W at 333 MHz

• Low-power consumption (typ. 1.5W)

– Internal: 1.5V

– I/O: 3.3V

– Reduced power mode (halt)

Features

• Package: 484-pin PBGA

• TX49/H3 core (on-chip IEEE754

compliant single/double precision

FPU)

• CPU maximum operating frequency:

300 MHz/333 MHz

• IEEE1149.1 (JTAG) support: debugging

support unit

• SDRAM controller

(4 channels: 64-bit/133 MHz)

• Package: 484-pin PBGA

64 pins are thermal ball for heat dissipation

• NAND flash memory controller
