ACE1202T Data Encryption Standard (DES) Trasmitter
PRELIMINARY
August 2001
ACE1202T
Data Encryption Standard (DES) Transmitter
General Description
The ACE1202T is a customizable transmitter implementing the
DES algorithm to encrypt a pulse-width-modulated (PWM) signal
transmitted through a radio frequency (RF) module. The ACE1202T
together with the ACE1202R
1
form an encoder/decoder chip-set
used in high-security applications.

The ACE1202T is a member of the ACE1202 (Arithmetic Control-
ler Engine) family of microcontrollers. The ACE1202 product
family is a dedicated programmable monolithic integrated circuit
for applications requiring high performance, low power, and small
size. It is a fully static part fabricated using CMOS technology. For
additional information regarding the ACE1202 family of
microcontrollers please see Fairchild Semiconductor鈥檚 web site at
www.fairchildsemi.com.
