DSM (Digital Signal Processor System Memory)
For Analog Devices ADSP-218X Family (5V Supply)
FEATURES SUMMARY
I
Glueless Connection to DSP
– Easily add memory, logic, and I/O to DSP
I
128K Byte Flash Memory
– For Bootloading and/or Data Overlay Memory
– Programmable Decoding and Paging Logic
allows accessing Flash memory as Byte DMA
(BDMA) and as External Data Overlay mem-
ory
– Rapidly access Flash memory with BDMA for
booting and loading internal DSP Overlay
memory. Alternatively access the same Flash
memory as External Data Overlay memory to
efficiently write Flash memory with code up-
dates and data, a byte at a time with no DMA
setup overhead
– Individual 16K Byte Flash memory sectors
match size of DSP External Data Overlay
window for efficient data management. Inte-
grated page logic provides easy DSP access
to all 128K Bytes.
– DSM connects to lower byte of 16-bit DSP
data bus. Byte-wide accesses to 8-bit BDMA
space. Half-word accesses to 16-bit Data
Memory Overlay and 16-bit I/O Mem space.
I
5V D
evices (±10%)
Up to 16 Multifunction I/O Pins
– Increase total DSP system I/O capability
– I/O controlled by DSP software or PLD logic
– 8mA I/O pin drive at 5 Vcc
I
I
General purpose PLD
– Over 3,000 Gates of PLD with 16 macro cells
– Use for peripheral glue logic to keypads, con-
trol panel, displays, LCD, UART devices, etc.
– Eliminate PLDs and external logic devices
– Create state machines, chip selects, simple
shifters and counters, clock dividers, delays
– Simple PSDsoft Express

I
In-System Programming (ISP) with JTAG
– Program entire chip in 10-20 seconds with no
involvement of the DSP
– Eliminate sockets for pre-programmed mem-
ory and logic devices
– Efficient manufacturing allows easy product
testing and Just-In-Time inventory
– Use low-cost FlashLINK
