4.4 Application Code Security
4.3.3
Pads
The CS485xx I/Os operate from the 3.3 V supply and are 5 V tolerant.
4.4 Application Code Security
The external program code may be encrypted by the programmer to protect any intellectual property it may contain. A
secret, customer-specific key is used to encrypt the program code that is to be stored external to the device. Contact your
local Cirrus representative for details.
5 Characteristics and Specifications
Note:
All data sheet minimum and maximum timing parameters are guaranteed over the rated voltage and temperature.
All data sheet typical parameters are measured under the following conditions: T = 25° C, C L = 20 pF,
VDD = VDDA = 1.8 V, VDDIO = 3.3 V, GNDD = GNDIO = GNDA = 0 V.
