Specifications subject to change without notice.
Stresses greater than those listed above may cause permanent damage to the device.
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V
readily accumulate on the human body and test equipment and can discharge without
detection. Although the ADSP-2191M features proprietary ESD protection circuitry,
permanent damage may occur on devices subjected to high-energy electrostatic
discharges. Therefore, proper ESD precautions are recommended to avoid perfor-
mance degradation or loss of functionality.

Test conditions: V DDINT = 2.50 V; HCLK (peripheral clock) frequency = CCLK/2 (core clock/2) frequency; T AMB = 25ºC.
Test conditions: V DDINT = 2.65 V; HCLK (peripheral clock) frequency = CCLK/2 (core clock/2) frequency; T AMB = 25ºC.
PLL, Core, peripheral clocks, and CLKIN are disabled.
PLL is enabled and Core and peripheral clocks are disabled.
