Peripheral Simulation

For Dallas Semiconductor DS89C440 — 1 Clock per Machine Cycle

Simulation support for this peripheral or feature is comprised of:

  • Accurate simulation of special on-chip features.

These simulation capabilities are described below.

1 Clock per Machine Cycle

The standard 8051 MCU requires 12 clocks per machine cycle. The DS89C430/DS89C440/DS89C450 MCUs contain a high-speed 8051-compatible core that requires only 1 clock per machine cycle. As a result, the fastest instruction on a standard 8051 will execute 12 times faster on these MCUs.
