Atmel ATA5830/ATA5830N
The Atmel
Atmel ATA5830 is partitioned into several sections; an RF frontend, a digital baseband, and a
low power 8 bit AVR microcontroller. The product is designed for the ISM frequency bands in
the ranges of 310 to 318MHz, 418 to 477MHz and 836 to 928MHz. External part count is kept
to a minimum due to the very high level of integration in this device. By combining outstanding
RF performance with highly sophisticated baseband signal processing, robust wireless com-
munication can be easily achieved. The receive path uses a low-IF architecture with an
integrated double quadrature receiver and digitized IF processing. This results in high image
rejection and excellent blocking performance. The transmit path uses a closed loop frac-
tional-N modulator with gaussian shaping and preemphasis functionality for high data rates. In
addition, the highly flexible and configurable baseband signal processing allows the trans-
ceiver to operate in several scanning, wake-up and automatic self polling scenarios. For
example, during polling the IC can seek certain message content (IDs) and save valid tele-
gram data in the FIFO buffer for later retrieval. The device possess two receive paths that
enable parallel search for two telegrams with different modulations, data rates, wake-up condi-
tions, etc. The highly configurable and autonomous scanning capability enables polling of up
to five application channels such as 3-channel RKE, TPMS, PEG. The configuration of the
transceiver is stored in a 512 byte EEPROM. The SPI allows for external control and reconfig-
uration of the device. The internal microcontroller and 6 KB Flash can be used to add
customer extensions to the Atmel firmware. The debug wire and ISP interface are available for
programming purposes.
The transceiver is designed to be used in the following application areas:
Three applications with a total of 5 channels are supported by the Atmel firmware for autono-
mous self polling.
• Remote Keyless Entry System (RKE)
• Passive Entry Go System (PEG)
• Tire Pressure Monitoring System (TPM,TPMS)
• Remote Start System (RS)
• Remote Control System, e.g. garage door open
• Smart RF applications
• Telemetering Systems
