Toshiba Launches World's First One Chip 32-bit CISC Microcomputers

23 January, 2001

Performance capabilities compare with those of RISC microcomputers

Tokyo--Toshiba Corporation today announced the world's first 32-bit complex instruction set computer (CISC) microcomputers integrating 128 kilobytes (KB) of ROM and 6KB of RAM. Two products, TMP92CW53F and TMP92CW10F, have been developed around a new 32-bit central processing unit (CPU) core, TLCS-900/H1, which offers lower power consumption and enhanced processing capabilities.

Both new microcomputers incorporate a phase-locked loop (PLL) circuit that converts 10MHz external signals to the CPU's internal clock rate of 20MHz, and achieve a power consumption of 75 milliwatts, the lowest reported in the industry. The low power and high performance specs of the new cores makes them highly attractive for incorporation in personal digital assistants (PDA), CD-ROMs, DVD-ROMs, system controllers for audio applications, and automotive uses.

Samples of TMP92CW53F and its development tools are available now, and mass production is slated to start in June 2001. Samples of TMP92CW10F will be available in March 2001 and mass production will start from September 2001. Samples of the microcomputer-embedded flash memory that users require for debugging will also be made available.
