Introduction
The TMS320F20x/F24x digital signal processors (DSPs) contain on-chip flash
EEPROM (electrically-erasable programmable read-only memory). The em-
bedded flash memory provides an attractive alternative to masked program
ROM. Like ROM, flash memory is nonvolatile, but it has an advantage over
ROM:
in-system
reprogrammability.
This chapter discusses basic flash memory technology, introduces the flash
memory module of the ’F20x/F24x DSP, and lists the benefits of flash memory
embedded in a DSP chip.
