Description The ATR2740 is a fully integrated processing unit which covers all DAB- (Eureka 147, ETS 300 401) related digital tasks like DAB OFDM demodulation and decoding, audio source decoding, data decoding, as well as time and frequency synchronization. The device consists of a high-performance 32-bit RISC ARM7TDMI core, an additional TeakDSPCore, embedded memories, an analog-to-digital converter (ADC), as well as a DAB channel demodulator and decoder IP, and two independent audio source decoder engines. A large variety of interfaces, including USB, SPI, USART and RDI, are provided. The ATR2740 baseband processor is controlled by a standard ARM7TDMI core, which is a very well-known controller. This allows the designers to work with standard tools, which results in reduced development costs and very fast time to market. The ARM7TDMI core is designed to perform the DAB receiver tasks, MMI and further user software extensions such as MP3 decoding or data decoding. The ATR2740 is manufactured using Atmel’s high-density CMOS technology. By combining all functions on one SoC (System-on-Chip), including a wide range of peripheral functions on a monolithic chip, the ATR2740 provides a highly flexible and cost-effective solution for DAB applications. The advanced Atmel technology and the architecture of the ATR2740 enable maximum performance at a very low current consumption. The wide flexibility offered by the ATR2740 is due to the large variety of interfaces supported. For control functions, UART, USB, and SPI are available. As data interfaces, an SSO, SFCO, US Band RDI, as well as two audio outputs (either I2S or SPDIF), are available. Due to the high integration of the device, the external component count is as low as only two external parts; a simple crystal and a 16-MB flash memory are required to run the full DAB function. All RAM, such as interleaving or program memory, as well as the ADC are incorporated into the device. The part works perfectly together with Atmel’s DAB front-end parts. The processing power available with the ATR2740 is sufficient to enable the part to decode the full DAB data rate of 1.8 Mbits. In addition, there is still unused processing power available on the ARM7TDMI controller for customer software. It is easy to run a complete MP3 player without the need to add extra hardware to the device. A complete set of tools for hardware and software, including documentation that allows easy design-in and a fast time to market, is available on request. 2 ATR2740 4816FS–DAB–07/08 ATR2740 Figure 1-1.
