1 / 61 page  1/61 September 2002 DSM2190F4V DSM (Digital Signal Processor System Memory) For Analog Devices ADSP-2191 DSPs (3.3V Supply) FEATURES SUMMARY s Glueless Connection to DSP – Easily add memory, logic, and I/O to the Exter- nal Port of ADSP-2191 DSP s Dual Flash Memories – Two independent Flash memory arrays for stor- ing 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 sec- tors (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 exter- nal 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 boundary s Up to 16 Multifunction I/O Pins – Increase total DSP system I/O capability – I/O controlled by DSP software or PLD logic s General purpose PLD – Over 3,000 Gates of PLD with 16 macro cells – Use for peripheral glue logic to keypads, control panel, displays, LCDs, and other devices – Eliminate PLDs and external logic devices – Create state machines, chip selects, simple shifters and counters, clock dividers, delays – Simple PSDsoft ExpressTM software...Free s Operating Range –VCC: 3.3V±10%; Temperature: –40 oC to +85oC Figure 1. Packages s In-System Programming (ISP) with JTAG – Program entire chip in 10-25 seconds with no in- volvement of the DSP – Links with ADSP-2191 JTAG debug port – Eliminate sockets for pre-programmed memory and logic devices – ISP allows efficient manufacturing and product testing supporting Just-In-Time inventory – Use low-cost FlashLINKTM cable with PC s Content Security – Programmable Security Bit blocks access of de- vice programmers and readers s Zero-Power Technology – As low as 25 µA standby current s Packaging – 52-pin PQFP or 52-pin PLCC s Flash Memory Speed, Endurance, Retention – 150 ns, 100K cycles, 15 year retention PLCC52 (K) PQFP52 (T) |
