ADSP-21365/6
Preliminary Technical Data
MAXIMUM POWER DISSIPATION
The data in this table is based on theta JA (
θ
JA
) established per
JEDEC standards JESD51-2 and JESD51-6. See Engineer-to-
Engineer note (EE-TBD) for further information. For informa-
tion on package thermal specifications, see
Thermal
Characteristics on page 44

ESD SENSITIVITY
TIMING SPECIFICATIONS
The ADSP-21365/6’s internal clock (a multiple of CLKIN) pro-
vides the clock signal for timing internal memory, processor
core, serial ports, and parallel port (as required for read/write
strobes in asynchronous access mode). During reset, program
the ratio between the processor’s internal clock frequency and
external (CLKIN) clock frequency with the CLKCFG1–0 pins
(see
Table 7 on page 14
). To determine switching frequencies
for the serial ports, divide down the internal clock, using the
programmable divider control of each port (DIVx for the serial
ports).
The ADSP-21365/6’s internal clock switches at higher frequen-
cies than the system input clock (CLKIN). To generate the
internal clock, the processor uses an internal phase-locked loop

Stresses greater than those listed above may cause permanent damage to the device.
These are stress ratings only; functional operation of the device at these or any other
conditions greater than those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
CAUTION
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-21365/6 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 performance degradation or loss of functionality.
