RF transceiver and RF receiver ICs from Atmel for the automotive and consumer markets

Atmel Corporation has released ATA5830 and ATA5780, the next monolithic RF transceiver and RF receiver devices. The multiband devices are designed for the ISM frequency bands in the ranges of 310 to 318 MHz, 418 to 477 MHz and 836 to 928MHz, and are suggested for today’s demanding automotive remote keyless entry (RKE), remote start, passive entry go (PEG), and tire pressure monitoring systems (TPMS).

The monolithic devices feature Atmel AVR microcontroller core enabling the devices to poll multiple application channels to support, for example, the RKE/PEG, Remote Start and TPMS system with a single IC instead of having multiple ICs, which results in a very cost efficient solution.

"Atmel is an automotive expert and has over 25 years of automotive design expertise. The introduction of these new products continues demonstrating Atmel’s commitment to the automotive industry," said Klaus Herhoffer, Car Access Marketing Manager, Atmel Corporation. "In addition, these new products provide designers the flexibility to optimize their RF solutions for TPMS, RKE, and PEG without system performance sacrifices. These new RF devices further solidify Atmel’s leadership in the automotive RF market."

The ATA5830 and ATA5780 are pin-compatible devices so that same printed circuit board design can be used for for both the unidirectional and bidirectional car access system.

The highly sensitive devices (typical -109dBm, 10kBps Manchester data rate, FSK modulation with +/-10kHz frequency deviation, IF bandwidth 165kHz) provide a high image rejection and excellent blocking performance (typical 64dBc at 1MHz, IF bandwidth of 165kHz) for the customer application. The transceiver's maximum power-down current of 600nA ensures that customers enjoy maximum battery life and battery size is kept to a minimum.
