CEA 3207A

ARM7-Based Car Entertainment Controller

The CEA 3207A is a device of Micronasâ

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

I2C 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.
