Atmel launches an integrated high-performance microcontroller with the industry's lowest power consumption RF transceiver

Leader Corporation of Microcontrollers and Touch Technology Solutions announced a new generation of RF transceivers based on low-power, high-performance microcontrollers designed for automotive markets and intelligent RF markets. The newly launched three devices (ATA5831, ATA5832 and ATA5833) have the industry's lowest power consumption, high sensitivity and output power, suitable for automotive applications, including remote control non-spoonful access control (Rke), passive no access control (PEG), remote control start ( RS) and Tire Pressure Monitoring (TPMS) system. The new RF series is also applicable to various intelligent RF applications, including RF systems such as garage door remote control switch or telemetry applications. Low power is a key requirement for automotive access control and intelligent RF systems, especially small batteries. These new devices have achieved low power consumption by eliminating outstanding blocking capabilities of interference. Due to almost no interference, digital logic is rarely awakened, thereby bringing typical values to 9.8mA reception mode (low frequency band, 310-318MHz, 418-477MHz, 1.2mA, 21MS circulation, 3-channel polling) power consumption And a typical value of 9.4mA / 13.8mA (low frequency band, pout = 6dBm / 10dBm) power consumption. Therefore, the terminal application device can use a smaller battery to achieve a miniature terminal application design. In order to extend the transmission distance of the RF system, the normal operation is achieved, high sensitivity and high output power are also critical. The new RF transceiver has excellent sensitivity, which can achieve a typical value of -123dBm (0.75kb / s, FSK, Manchester code, 433.92 MHz) and -109dBM typical value (20kb / s, ASK, Manchester code, 433.92 MHz). Combined with a typical value of 14.5 dBm high output power, the series of devices enable excellent long-range communication performance. These single-chip devices combine RF function and verified Eitmel AVR microcontroller kernel. Since the configuration can be configured via the EEPROM, it is possible to make programming via a serial peripheral interface (SPI), quickly adapt to the demand for each application - even during operation. Customers can also achieve additional to existing firmware functions via Flash (ATA5831) or user ROM (ATA5832) as needed. The new RF transceiver series includes the following devices: • ATA5833: Using the integrated firmware, an integrated RF transceiver integrated circuit (IC). • ATA5831: The firmware is included in the read-only memory (ROM), which can meet the software requirements of a particular application via Flash. • ATA5832: Cost Optimization Version of ATA5831, where customer software uses ROM mask. In order to further reduce development and production complexity, help reduce market time, Eitmel this series of RF products, use pin, function and RF matching parameters, to ensure the maximum development of unidirectional and two-way systems To minimize design workload. The same printed circuit board design can be used for one-way and bidirectional automobile access control systems.
