The Andes product family is Calterah's new generation of auto-grade mmWave radar SoCs, representing the most leading-edge mmWave radar technology, enabling 4D premium radar and imaging radar functions. The Andes family includes two part numbers: CAL77C644-AF and CAL77C844-AF. CAL77C644-AF can be applied to forward-looking radar and high-performance corner radar, while CAL77C844-AF supports the Flex-Cascading^® functionality, allowing cascading of any number of chips to achieve different scales of 4D imaging radar, thus empowering perception of L3+ autonomous driving systems.
Based on Calterah’s new-generation product platform, the Andes SoCs have the most cutting-edge designs in computing power, RF module, Flex-Cascading^®, debugging system, cybersecurity, etc.
Computing power: The quad-core CPU provides over 2000 DMIPS of computing power. The computing speed of the DSP core is three times that of its competing products. And Calterah's proprietary RSP achieves ultra-fast processing of radar signals.
RF module: The Andes SoCs boast a 7-bit phase shifter based on transmission line design, supporting functions such as flexible generation of various waveforms and precise digital compensation unit.
Cascading functionality: The Andes chip products offer Chip-to-Chip (C2C) interfaces for data exchange, enabling the Flex-Cascading^® function to connect multiple chips, which simplifies software design and operation. The C2C interfaces also support other functions such as distributed signal processing.
Debugging system: The debugging system of Andes SoCs provides various interfaces such as JTAG and Aurora, multiple data channels, and analysis modules.
Cybersecurity: The Andes SoCs use the “Security Island" design, supporting hardware acceleration for all encryption and decryption algorithms.
