DSM2190F4
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”, meaning they
automatically go to standby between memory ac-
cesses or logic input changes, producing low ac-
tive and standby current consumption, which is
ideal for battery powered products.
A programmable security bit in the DSM protects
its contents from unauthorized viewing and copy-
ing. When set, the security bit will block access of
programming devices (JTAG or others) to the
DSM Flash memories and PLD configuration. The
only way to defeat the security bit is to erase the
entire DSM device, after which the device is blank
and may be used again. The DSP will always have
access to Flash memory contents through the 8-bit
data port even while the security bit is set.
