ACE1202R Data Encryption Standard (DES) Receiver
PRELIMINARY
August 2001
ACE1202R
Data Encryption Standard (DES) Receiver
General Description
The ACE1202R is a custom receiver implementing the DES
algorithm. The receiver is used to decrypt a pulse-width modu-
lated (PWM) encrypted signal transmitted by a radio frequency
(RF) transmitter using the ACE1202T
1
. Together, the ACE1202R
and ACE1202T form an encoder/decoder chip-set used in high
security applications.

The ACE1202R 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 refer Fairchild Semiconductor鈥檚 web site
