TOSHIBA RISC PROCESSOR
TMPR4927ATB-200
TOSHIBA RISC PROCESSOR
TMPR4927ATB-200
(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
• TX49/H2 core with an integrated IEEE 754-compliant FPU for single- / double-precision operations
• 4-channel SDRAM Controller ( 64-bit 100MHz )
• 8-channel External Bus Controller
• 32-bit PCI Controller ( 32-bit 33 / 66 MHz )
• 4-channel Direct Memory Access ( DMA ) Controller
• 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 TX4927 operates with the 1.5V Int. and the 3.3V I/O, while supporting a low-power ( Halt ) mode.
• CPU maximum operating frequency: 200 MHz
• IEEE1149.1 (JTAG) support: Debug Support Unit ( Enhanced JTAG )
• 420-pin TBGA

2.5 TX4927 Peripheral Circuit FEATURES
n External Bus Controller ( EBUSC )
The External Bus Controller generates necessary signals to control external memory and I/O
devices.
• 8 channels of chip select signals, enabling control of up to eight devices
• Supports access to ROM ( including mask ROM, page mode ROM, EPROM and
EEPROM), SRAM, flash ROM, and I/O devices
• Supports 32-bit, 16-bit and 8-bit data bus sizing on a per channel basis
• Supports selection among full speed (uo to 100MHz ), 1/2 speed ( up to 50MHz), 1/3
speed ( uo tp 33MHz ) and 1/4 speed ( up to 25MHz) on a per channel basis
• Support specification of timing on a per channel basis
• The user can specify setup and hold times for address, chip enable, write enable, and
output enable signals
• Supports memory sizes of 1M byte to 1G byte for devices with 32-bit data bus, 1M byte
to 512M bytes for devices with 16-bit data bus, and 1M byte to 256M bytes for devices
with 8-bit data bus
n DMA Controller ( DMAC )
The TX4927 contains a 4-channel DMA controller that executes DMA transfer to memory
and I/O devices.
• 4-channel independently handling internal / external DMA requests
• Supports DMA transfer with built-in serial I/O controller and AC-link controller based on
internal DMA requests
• Supports signal address ( fly-by DMA ) and dual address transfers in external I/O DMA
transfer mode using external DMA requests
• Supports transfer between memory and external I/O devices having 32 / 16 / 8-bit data
bus
• Supports memory-to-memory copy mode, with no address boundary restrictions
• Supports burst transfer of up to 8 double words for a single read / write
• Supports memory fill mode, writing double-word data to specified memory area
• Supports chained DMA transfer
