FEATURES
SUMMARY s Glueless Connection to DSP – Easily add memory, logic, and I/O to the External Port of ADSP-2191 DSP s Dual Flash Memories – Two independent Flash memory arrays for storing DSP code and data. DSP may access the two arrays concurrently (read from one while erasing or writing the other) – 256K x 8 Main Flash memory divided into 8 sectors (32KByte each) – Ample storage for booting DSP code/data upon reset and subsequent code swaps – Large capacity for data recording – 32K x 8 Secondary Flash memory divided into 4 sectors (8 KByte each). Multiple uses: – Small sector size ideal for small data sets, and calibration or configuration constants – Store custom start-up code in one or more sectors and configure DSP to run from external memory upon reset (no boot) – Concatenate Secondary Flash with Main Flash for total of 288 KBytes – Each Flash sector can be write protected. – Built-in programmable address decoding logic allows mapping individual Flash sectors to any address b...
