MOTOROLA
EC000 CORE PROCESSOR USER’S MANUAL

FlexCore custom processors are ideal for:
High-volume users of 8-, 16-, and 32-bit integrated solutions requiring higher system
performance whose needs are not met by standard 68300 Family devices.
Designers of high-volume applications who need to reduce cost, space, and/or power
consumption.
Third-party technology providers who want to deliver their proprietary application-spe-
cific technology to a worldwide marketplace.
To develop a solution that best suits system requirements in the shortest time frame, inte-
grated processor design is performed by the designer using a methodology created, tested,
and documented by Motorola. The resulting netlist is then laid out by Motorola, verified, and
fabricated in silicon. This enables FlexCore integrated processors to be produced quickly
and cost-effectively, with the resulting device containing all features needed for the system.
To implement the application-specific logic, the designer uses Motorola's standard cell
library. This library offers an extensive range of design elements, memory configurations,
and an expanding array of peripheral modules. Each cell in the library has been designed
for optimum size and performance. The added flexibility of high-speed, high-density cells
allows the designer to achieve the most cost-effective solution while satisfying critical timing
requirements. The standard cell library has been thoroughly characterized and maintained
to ensure a smooth transition from a simulated design to working silicon. A custom part may
also become a standard product if both Motorola and the customer desire to do so. Standard
products are sold on the open market, allowing costs to be spread over additional units,
resulting in lower component prices for high-volume users.
Third-party technology providers can use the same methodology to combine their applica-
tion-specific systems expertise with a core processor. The resulting device is manufactured
by Motorola and can be delivered to the marketplace through either the technologist’s or
Motorola’s marketing and sales channels.
