TENTATIVE

INTEGRATED CIRCUIT

TOSHIBA RISC PROCESSOR

TMPR4937XB-300 (TX4937)

(64-bit RISC MICROPROCESSOR)

1. GENERAL DESCRIPTION

The TMPR4937TB, to be referred as TX4937 MIPS RISC micro-controller is a highly

integrated ASSP solution based on Toshiba’s TX49/H3 processor core, a 64-bit MIPS

I,II,III ISA Instruction Set Architecture (ISA) compatible with additional instructions. The

TX4937 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

•

TX49/H3 core with an integrated IEEE 754-compliant FPU for single- and double-precision operations

4-channel SDRAM Controller ( 64-bit 133MHz )

8-channel External Bus Controller

32-bit PCI Controller ( 32-bit 33 / 66 MHz )

8-channel Direct Memory Access ( DMA ) Controller (4-channel are for ACLC)

2-channel Serial I/O Port

Parallel I/O Port (up to 16-bit)

3-channel Timer / Counter

AC-Link ( AC97 Interface )

Low power dissipation ( Typ. 1.5 W )

The TX4937 operates with the 1.5V core and the 3.3V I/O, while supporting a low-power ( Halt ) mode.

CPU maximum operating frequency: 300 MHz

IEEE1149.1 (JTAG) support: Debug Support Unit ( Enhanced JTAG )

484-pin PBGA ( with 64pin thermal ball )
