TMS470R1A256
16/32-Bit RISC Flash Microcontroller
SPNS100–NOVEMBER 2004
Flash read
The A256 Flash memory is configurable by the SYS module to be addressed within the range of 0x0000_0000 to
0xFFE0_0000. The Flash is addressed through memory selects 0 and 1.
NOTE:
The Flash external pump voltage (V
CCP
) is required for all operations (program, erase,
and read).
Flash pipeline mode
When in pipeline mode, the Flash operates with a system clock frequency of up to 48 MHz (versus a system
clock in normal mode of up to 24 MHz). Flash in pipeline mode is capable of accessing 64-bit words and
provides two 32-bit pipelined words to the CPU. Also in pipeline mode, the Flash can be read with no wait states
when memory addresses are contiguous (after the initial 1-or 2-wait-state reads).
NOTE:
After a system reset, pipeline mode is disabled (ENPIPE bit [FMREGOPT.0] is a 0). In
other words, the A256 device powers up and comes out of reset in non-pipeline
mode. Furthermore, setting the Flash configuration mode bit (GLBCTRL.4) will
override pipeline mode.
Flash program and erase
The A256 device Flash has one 256K-byte bank that consists of fourteen sectors. These fourteen sectors are
sized as follows:
SECTOR NO.

The minimum size for an erase operation is one sector. The maximum size for a program operation is one 16-bit
word.
NOTE:
The Flash external pump voltage (V
CCP
) is required for all operations (program, erase,
and read).
