8-Bit Core Yields MCUs With 16-Bit Performance

Toshiba America Electronic Components (TAEC) has a new 8-bit microcontroller core with performance comparable to that of 16-bit MCUs. The TLCS-870/C1 core can process one instruction in a single clock cycle, enabling faster processing at lower frequencies, reduced noise, and lower power consumption compared with the company’s previous 8-bit cores.

The core has a large-capacity address space that’s expandable to 128 kbytes. It’s well suited for a wide range of jobs, from small-scale applications like portable devices to large-scale applications requiring large-capacity ROM, such as air conditioners, washing machines, and other white goods.

The expanded address space was attained with a memory-management method that manages code and data in separate areas. Up to 128 kbytes of address space can be implemented in an 8-bit MCU without any adverse consequences. Such consequences could include increased footprint due to address-bus expansion or degraded processing speed, which is common with the alternative memory-bank method.

The new core family helps reduce system cost by integrating must-have features such as a voltage-detection circuit, a power-on reset circuit, and an on-chip debug circuit. The TLCS-870/C1 core is binary compatible with previous Toshiba 8-bit MCUs, so existing software resources can be used.

TAEC plans to introduce its first new products based on the new core in the fourth quarter of 2006.
