3.1 Special Handling Instructions
The AMBE-2000 uses the TM320-LC541-66 core. For more details on handeling, electrical characteristics, packaging, or
timing constraints please refer to the TMS320-C54x manual found at
http://www-s.ti.com/sc/psheets/sprs039c/sprs039c.pdf
(Adobe Acrobat). Although the AMBE-2000 Vocoder Chip incorporates input protection circuitry, to avoid damage from
the accumulation of a static charge, industry standard electrostatic discharge precautions and procedures must be employed
during handling and mounting.
The 100 pin TQFP package design of the AMBE-2000 Vocoder Chip allows it to be mounted by infrared reflow, vapor-
phase reflow or equivalent processes. The peak package body temperature must not exceed 220
°
C.
The AMBE-2000 Vocoder Chip requires baking before mounting, if any of the following conditions exist:
Humidity indicator card (included in packaging) shows exposure to > 20 %
when read at 23
°
C + 5
°
C
Devices were not shipped in a package designated as “moisture
controlled.”
Not mounted within 168 hours of receipt, at factory conditions of < 30
°
C
and < 60% RH
If the device has not been stored at < 20% RH
DVSI’s recommended bake out procedures:
For low-temperature device containers: 192 hours at 40
°
C + 5
°
C / -0
°
C
and < 5% Relative Humidity
For high-temperature device containers : 24 hours at 125
°
C + 5
°
C.
3.1.1 Storage
To insure maximum shelf life in long term storage, AMBE-2000 Vocoder Chips should be kept in a moisture controlled
package at <40
°
C and <90% Relative Humidity
