2.1. About the CG092

The CG092 is a simple cache for on-chip embedded flash (eFlash). The CG092 design is optimized for fetching Cortex-M3 or Cortex-M4 instructions directly from an eFlash. The main benefit of the CG092 is improved power efficiency, but there are also improvements in code fetching performance.

The figure below shows the connections in a typical Flash subsystem:
