MCU-based RF transceiver ICs consume low power

MCU-based RF transceiver ICs consume low power

Designed specifically for the automotive and smart RF markets, the ATA5831, ATA5832 and ATA5833 family of microcontroller-based RF transceivers achieve low-power consumption through its blocking capabilities, which eliminate disturbances. With few disturbances, the digital logic is rarely awakened, resulting in a current consumption as low as 9.8 mA typical in receive mode (low-band, 310-318 MHz, 418-477 MHz, 1.2 mA, 21 ms cycle, 3-channel polling) and 9.4 mA/13.8 mA typical in transmit mode (low-band, Pout = 6dBm/10dBm).

The parts also provide a sensitivity at 123 dBm typical (0.75 kbit/s, FSK, Manchester code, at 433.92 MHz) and 109 dBm typ. (at 20 kbit/s, ASK, Manchester code, at 433.92 MHz), respectively. Combined with the high output power of up to 14.5 dBm typical, excellent long-distance operation performance can be achieved.

The monolithic devices combine RF functionality with a proven Atmel AVR microcontroller core. Since the devices can be configured through an EEPROM, adaptation to the individual application’s needs can be quick and be programmed via serial peripheral interface (SPI) – even on-the-fly during operation. If customer-specific adaptions are required, the existing firmware can be supplemented via Flash (ATA5831) or user ROM (ATA5832).($2.90, ea/50,000 available now)
