Description
The MC68LC302 excels in several applications areas.
First, any application using the MC68302,but not needing all three serial channels is a potential candidate for the MC68LC302. Note however, that the MC68LC302 sacrifices most of the provision for external bus mastership, thus the MC68LC302 may not be appropriate where the MC68302 is used as part of larger systems.
Second, the MC68LC302 excels in low power and portable applications. The inclusion of a static 68000 core, coupled with the low power modes built into the device make it ideal for handheld, or other low power applications. The new 32 kHz or 4 MHz PLL option greatly reduces the total power budget of the designer’s board, and allows the MC68LC302 to be an effective device in low power systems. The MC68LC302 can then optionally generate a full frequency clock for use by the rest of the board. During low power modes, the new periodic interrupt timer (PIT) allows the device to awaken at regular intervals. In addition, two pins can awaken the device from low power modes.
Third, given that the MC68LC302 is packaged in a 100TQFP package, it allows the MC68LC302 to be used in space critical applications, as well as height critical applications such as PCMCIA cards.
Fourth, since the disable CPU mode (also known as slave mode) is still retained, the MC68LC302 can function as a fully intelligent DMA-driven peripheral chip containing serial channels, timers, chip selects, etc.
