5 / 61 page  5/61 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. Table 1. DSM2190F4V DSP Memory System Devices Table 2.
