The TMS320F28335PGFA is a Delfino Microcontroller for demanding control applications. The GPIO function is the default at reset. The peripheral signals that are listed under them are alternate functions. Some peripheral functions may not be available in all devices. The F28335 device contains 256K x 16 of embedded flash memory, segregated into eight 32K x 16 sectors. It also contains a single 1K x 16 of OTP memory at address range 0x380400-0x3807FF. The user can individually erase, program and validate a flash sector while leaving other sectors untouched. However, it is not possible to use one sector of the flash or the OTP to execute flash algorithms that erase/program other sectors. Special memory pipelining is provided to enable the flash module to achieve higher performance. The flash/OTP is mapped to both program and data space, therefore, it can be used to execute code or store data information.
