MC68SEC000AA20 QFP-64 MPU 32-bit 20MHz

The MC68SEC000 is a cost-effective static embedded processor engineered for low-power applications. In

addition to providing the substantial cost and performance benefits of the MC68EC000, the low-power mode of

the MC68SEC000 provides significant advantages in power consumption and power management. The typical

current consumption of the MC68SEC000 is only 0.5µA in static standby mode and 15.0mA in normal 3.3V

operation. The MC68SEC000 operates in either 3.3V or 5.0V systems. The remarkably low power consumption,

small footprint packages, and static implementation are combined in the MC68SEC000 for low-power

applications such as personal digital assistants, portable measuring equipment, electronic games, and batteryoperated hand-held consumer products.

The HCMOS MC68SEC000 static architecture is a direct replacement for the MC68EC000, which offers the

lowest cost entry point to 32-bit processing. The internal 32-bit architecture provides fast and efficient

processing that satisfies the requirements of sophisticated applications based on high-level languages. In

addition to being pin-for-pin compatible with the MC68EC000, the MC68SEC000 is object-code compatible with

any member of the M68000 Family. Complete code compatibility lets system designers reduce time to market

because they can rely on existing M68000 Family code and a broad base of established development tools.

The primary features of the MC68SEC000 embedded processor include the following:
