This document describes the STA1052 DSP/MCU system from STMicroelectronics, which is designed for CD-DA, CD-CA, and CD-ROM players. It features CD-R and CD-RW playback, audio decoding (MP3, WMA, AAC), CLV (1x, 2x, 4x) and CAV mode (6x), and more.
The STA1052 is a single-chip device designed to perform all functions related to reading optical disks. It integrates an embedded ARM7TDMI microcontroller with 384 KB internal ROM and handles tasks such as servo control, EFM demodulation, error correction, and software decoding of MP3, WMA, and AAC audio files.
The device operates within a temperature range of -40 °C to +85 °C.
The embedded 32-bit MCU operates at a frequency of 67 MHz.
