Flash Memory
Internal Memory
11 February 2010
The eCOG1X contains 512K bytes of on-chip flash memory for program and data storage, organised
as 256K words x 16 bits. The flash memory is programmed with and operates from the eCOG1X’s
normal 3.3V supply; no external high voltages are required for erasing or programming.
The flash memory contains 11 sectors of various sizes. The following table shows the organisation of
the flash memory:
The flash memory can be programmed via the eICE debug port or in-system by the CPU. It supports
the following functions.

The flash memory can be used in three different operating modes, each with different power
consumption and timing requirements. These modes are:
The eCOG1X contains 24K bytes of on-chip static RAM, organised as 12K x 16 bits. The internal
SRAM (IRAM) is divided into three banks. Bank 0 is always available, while banks 1 and 2 may be
enabled or disabled.

The flash memory has its fastest access time, but it also requires the largest power
supply current.
The power consumption is decreased significantly. The access time is increased such
that the CPU clock speed must be reduced or the device must be configured for a large
number of wait states on flash memory read cycles.
The flash memory draws only leakage current. However, it cannot be accessed in this
mode for either instruction fetch or data read cycles.
