32-bit RISC microprocessor: TX39 Family

The TX39 Family of RISC microprocessors for embedded use were developed by Toshiba based on the R3000A architecture designed by MIPS Technologies, Inc. It is an original Toshiba 32-bit processor family. Using the TX39/H or the high-speed TX39/H2, TX39/H3 as the CPU core for gate arrays and cell-based ICs, you can accomplish a high level of integration in your system.

Features

High-performance RISC technology

R3000A architecture
Internal operating frequency
TX39/H: 92 MHz, TX39/H2, H3: 133 MHz
Built-in cache memory
Non-blocking load function
- The instructions which follow the instruction currently being executed are executed while the cache is being refilled.
DSP function
- 32-bit multiply-accumulate (MAC) operations take only one clock cycle to execute.

Functions suitable for embedded applications

Reduced code size and improved performance
- Use of branch-likely instructions
- Hardware interlock function
Increased real-time capability
- Cache lock function
Real-time debugger system connection
- Real-time debugging is possible while cache is on.
