Features
TX49/L3 Processor Core
TX49/L3 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 32-bit
Core and Cache are connect with 64-bit Internal bus. External bus is 32-bit SysAD-bus I/F. This interface
is compatible with the R4300, and R5000 system interfaces.
Power management
Internal: 1.5 V
I/O: 3.3 V or 2.5 V
The TX49/L3 Processor support Power management mode (Halt, Doze)
Maximum operating frequency
The TX49/L3 Processor’s maximum operating frequency are 200 MHz.
The SysAD-bus I/F and TX49/L3 Processor’s maximum operating frequency is set by External pin
(DivMode[1:0]).
Ex. Core’s operating frequency is 300 MHz
