CEA 3207A
ARM7-Based Car Entertainment Controller
The CEA 3207A is a device of Micronas’
32-bit Car Entertainment Controller family
based on an ARM7TDMI CPU core.
Like the already available CDC 3207G, the
CEA 3207A is part of the LEAP family con-
cept (Low Emission Automotive Processor).
The microcontroller with its ARM7TDMI
RISC CPU core allows two states of opera-
tion: ARM state with 32-bit instructions and
THUMB state with 16-bit instructions.
It is suited for entertainment-related appli-
cations like car radio or navigation systems.
The current version CEA 3207A offers
32 kBytes of SRAM, 512 kBytes of Flash,
and 8 kBytes of boot ROM. Communication
is possible via two FullCAN modules, two
I
2
C modules and two UART or SPI modules
each. Due to its scalable architecture, fur-
ther derivatives can be obtained within short
lead time. An upgrade version with 1 MByte
Flash and up to 64 kBytes RAM, as well as
a downgrade version with 256 kBytes Flash
and 16 kBytes RAM in the same package is
planned. All devices have the patented
built-in ERM (EMI Reduction Module) and
are operated on a single 5-V power supply.
