Maker : STMicroelectronics

Pinouts :
DSM2190F4V datasheet

Description :

FEATURES SUMMARY
■Glueless Connection to DSP
– Easily add memory, logic, and I/O to the Exter
nal Port of ADSP-2191 DSP
■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

■ Up to 16 Multifunction I/O Pins
– Increase total DSP system I/O capability
– I/O controlled by DSP software or PLD logic
■ 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 Express
■ 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 FlashLINK
TMcable with PC
■Content Security
– Programmable Security Bit blocks access of de
vice programmers and readers
■Zero-Power Technology
– As low as 25µA standby current
■Packaging
– 52-pin PQFP or 52-pin PLCC
■Flash Memory Speed, Endurance, Retention
– 150 ns, 100K cycles, 15 year retention
