DSM2150F5V
DSM (Digital Signal Processor System Memory)
for Analog Devices DSPs (3.3V Supply)
FEATURES SUMMARY
s Glueless Connection to DSP
– Easily add memory, logic, and I/O to the
External Port of ADSP-218x, 219x, 2106x,
2116x, 2153x, and TS101 families of
DSPs from Analog Devices, Inc.
s Dual Flash Memories
– Two independent Flash memory arrays
for storing DSP code and data
– Capable of read-while-write concurrent
Flash memory operation
– Device can be configured as 8-bit or 16-bit
– Built-in programmable address decoding
logic allows mapping individual sectors of
each Flash array to any address boundary
– Each Flash sector can be write protected
s 512 KByte Main Flash memory
– Ample storage for boot loading DSP code/
data upon reset and subsequent code
swaps
– Large capacity for storing tables and
constants or for data recording
s 32 KByte Secondary Flash memory
– Smaller sector size ideal for storing
calibration and configuration constants.
Eliminate external serial EEPROM.
– Optionally bypass internal DSP boot ROM
during start-up and execute code directly
from Secondary Flash. Use for custom
start-up code and In-Application
Programming (IAP).
s Up to 40 Multifunction I/O Pins
– Increase total DSP system I/O capability
– I/O controlled by DSP software or PLD
logic
s General purpose PLD
– Use for peripheral glue logic to keypads,
control panel, displays, LCDs, and other
devices
– Over 3,000 gates of PLD with 16 macro
cells
– Eliminate PLDs and external logic devices
– Create state machines, chip selects,
simple shifters and counters, clock
dividers, delays
– Simple PSDsoft Express^™ development
software, free from www.st.com/psm

TQFP80 (T)
s In-System Programming (ISP) with JTAG
– Program entire chip in 15-35 seconds with
no involvement of the DSP
– Optionally links with DSP JTAG debug
port
– Eliminate need for sockets and pre-
programming of memory and logic
devices
– ISP allows efficient manufacturing and
product testing supporting Just-In-Time
inventory
– Use low-cost FlashLINK^™ cable with any
PC. Available from www.st.com/psm.
s Content Security
– Programmable Security Bit blocks access
of device programmers and readers
s Operating Range
– V_CC: 3.3V ± 10%, Temp: –40°C to +85°C
s Zero-Power Technology
– 50µA standby current typical
s Flash Memory Speed, Endurance, Retention
– 120ns, 100K cycles, 15 year retention
