Product Summary

The DS80C320-MCG+ is a fast 80C31-compatible microcontroller. Wasted clock and memory cycles have been removed using a redesigned processor core. As a result, every 8051 instruction is executed between 1.5 and 3 times faster than the original for the same crystal speed. Typical applications of the DS80C320-MCG+ see a speed improvement of 2.5 times using the same code and same crystal. The DS80C320-MCG+ offers a maximum crystal rate of 33MHz, resulting in apparent execution speeds of 82.5MHz (approximately 2.5X).

Parametrics

DS80C320-MCG+ absolute maximum ratings: (1)Voltage Range on Any Pin Relative to Ground: -0.3V to (VCC + 0.5V); (2)Voltage Range on VCC Relative to Ground: -0.3V to +6.0V; (3)Operating Temperature Range: -40 to +85℃; (4)Storage Temperature Range: -55 to +125℃.
