MCU
The ZRS-152 is a microcontroller (MCU) from STMicroelectronics used in Carmedia systems. It is a 32-bit ARM Cortex-M4 processor with the built-in STM32L151 real-time clock, which allows for time-precise scheduling of audio recordings, images and video streams. The ZRS-152 provides integrated analog-to-digital conversion for audio and video signals, allowing for signal processing in real-time. It also integrates regulated power supply, Flash/SRAM memories, several serial communication protocols and general purpose I/O ports. Thanks to the built-in hardware acceleration, the ZRS-152 supports multiple audio and video codecs, such as MP3, AAC, H.264 and H.265.
