FLEX 10K Embedded Programmable Logic Device Family Data Sheet

The FLEX 10K architecture is similar to that of embedded gate arrays, the

fastest-growing segment of the gate array market. As with standard gate

arrays, embedded gate arrays implement general logic in a conventional

“sea-of-gates” architecture. In addition, embedded gate arrays have

dedicated die areas for implementing large, specialized functions. By

embedding functions in silicon, embedded gate arrays provide reduced

die area and increased speed compared to standard gate arrays. However,

embedded megafunctions typically cannot be customized, limiting the

designer’s options. In contrast, FLEX 10K devices are programmable,

providing the designer with full control over embedded megafunctions

and general logic while facilitating iterative design changes during

debugging.

Each FLEX 10K device contains an embedded array and a logic array. The

embedded array is used to implement a variety of memory functions or

complex logic functions, such as digital signal processing (DSP),

microcontroller, wide-data-path manipulation, and data-transformation

functions. The logic array performs the same function as the sea-of-gates

in the gate array: it is used to implement general logic, such as counters,

adders, state machines, and multiplexers. The combination of embedded

and logic arrays provides the high performance and high density of

embedded gate arrays, enabling designers to implement an entire system

on a single device.

FLEX 10K devices are configured at system power-up with data stored in

an Altera serial configuration device or provided by a system controller.

Altera offers the EPC1, EPC2, EPC16, and EPC1441 configuration devices,

which configure FLEX 10K devices via a serial data stream. Configuration

data can also be downloaded from system RAM or from Altera’s

BitBlasterTM serial download cable or ByteBlasterMVTM parallel port

download cable. After a FLEX 10K device has been configured, it can be

reconfigured in-circuit by resetting the device and loading new data.

Because reconfiguration requires less than 320 ms, real-time changes can

be made during system operation.

FLEX 10K devices contain an optimized interface that permits

microprocessors to configure FLEX 10K devices serially or in parallel, and

synchronously or asynchronously. The interface also enables

microprocessors to treat a FLEX 10K device as memory and configure the

device by writing to a virtual memory location, making it very easy for the

designer to reconfigure the device.
