TX49/H4 Processor Core

TX49/H4 Processor Core is a 64-bit RISC CPU core Toshiba developed based on the architecture of MIPS

for interactive consumer applications including Printer, Network and set-top terminals.

•

Internal bus width is 64-bit, External bus width is 64-bit or 32-bit.

Core and Cache are connected with 64-bit internal bus. External bus is 64-bit or 32-bit SysAD-bus I/F with

multiplexed address and data. This interface is compatible with the R4300, and R5000 system interfaces.

•

Power management

Internal: 1.25 V

I/O: 3.3 V or 2.5 V

The TX49/H4 Processor support Power management mode (Halt, Doze)

•

Maximum operating frequency

The SysAD-bus I/F and TX49/H4 Processor’s maximum operating frequency is set by External pin

(DivMode[2:0]).
