DESCRIPTION
DSM2180 devices bring In-System Programmable flash
memory, programmable logic and additional I/O to Analog
Devices ADSP-218x family of DSPs. The result is a simple,
flexible, two-chip solution featuring the flexibility of flash
memories and smart JTAG programming techniques for
manufacturing and field updates. The on-chip memory and
decode and paging logic make it easy to add large amounts of
external flash memory to the ADSP-218x family for boot
memory and/or Data Overlay Memory.
JTAG In-System Programming (ISP) reduces development time,
simplifies manufacturing flow and lowers the cost of field
upgrades. DSM devices also add programmable logic (PLD)
and additional configurable I/O pins to the DSP system. The
state of each I/O pin can be driven by DSP software or PLD
logic. PLD and I/O configuration are programmable by JTAG
ISP, just like the flash memory. Common uses for the PLD
include chip selects for external devices (i.e. UART), state-
machines, simple shifters and counters, keypad and control
panel interfaces, clock dividers, hand-shake delay, muxes, etc.
This eliminates the need for small external PLDs and logic
devices.
Configuration of PLD, I/O and flash memory mapping are
easily entered in a point-and-click environment using our
software development tool, PSDsoft Express™. This software is
available at no charge from www.st.com/psd
The two-chip combination of a DSP and a DSM device is ideal
for systems which have limitations on size, EMI levels and
power consumption. DSM memory and logic are “zero-
power”, this means they automatically go to standby between
memory accesses or logic input changes. This produces low
active and standby current consumption, which is ideal for
battery powered products.
