Product details

Overview

STA016T from STMicroelectronics is a single-chip MPEG-1/2/2.5 Layer III audio decoder with embedded CD-ROM (ISO 9660/Joliet) and ADPCM codec functionality, supporting sampling rates from 8 kHz to 48 kHz, bitrates up to 320 kbit/s, and GPSO output at 5 Mbit/s. It integrates I²S, SDI, and ADC interfaces, digital volume control, bass/treble equalization, and CDDSP handshake for CD player systems.

For engineers reviewing the STA016T datasheet, STA016T pinout, STA016T application, or STA016T equivalent, this device serves as a full-featured audio SoC for legacy CD/MP3 playback systems-requiring precise clock PLL configuration, I²C register-level control of decoding modes, and hardware-level coordination with CD servo controllers via CDDSP interface.

Technical Context

The STA016T implements a dual-engine architecture: an ISO/IEC 11172-3 and 13818-3.2 compliant MP3 decoder core handling stereo/dual/mono streams across MPEG-1/2/2.5 sampling frequencies (8–48 kHz), and a multistandard ADPCM encoder/decoder supporting DVI, G.721, G.723-24/40, and G.726 algorithms at 8–32 kHz sample rates and 8–32-bit word lengths.

Its embedded DSP firmware executes full CD-ROM stack layers-including ECC/EDC correction, ISO 9660/Joliet file system parsing, and Browsing Command Interpreter (BCI) for directory navigation-while offloading host MCU tasks via interrupt-driven I²C command flow and GPSO high-speed data transfer up to 5 Mbit/s.

IC Role / Device Role / Timing Role: Central audio SoC managing CDDSP communication, MP3/ADPCM decode, and I²S-to-DAC signal chain timing.

Use Value: Eliminates separate MP3 decoder and CD-ROM controller ICs, reducing BOM count and PCB area by >40%.

Use Scenario: Educational or kiosk CD-ROM players delivering audio-rich content with Joliet long filenames and directory hierarchy.

IC Role / Device Role / Timing Role: Full ISO 9660/Joliet file system decoder with embedded BCI and sector-level ECC/EDC correction.

Use Value: Enables plug-and-play CD-ROM media support without host OS dependency or external FAT/ISO parsing firmware.

Car Radio Systems

Legacy Embedded Media Players

Use Scenario: Automotive head units integrating CD, MP3, and voice memo (ADPCM) features in a single audio subsystem.

IC Role / Device Role / Timing Role: Dual-path audio processor supporting both CDDSP-linked CD playback and flash-based MP3/ADPCM streams.

Use Value: Shared digital volume, bass/treble, and mute controls across all sources - simplifies audio routing and calibration.

Use Scenario: Industrial or medical devices using CD-ROM for firmware updates or audio-guided diagnostics with voice prompts.

IC Role / Device Role / Timing Role: GPSO-driven ADPCM encoder for field-recorded voice notes and I²S output for local speaker playback.

Use Value: 5 Mbit/s GPSO throughput enables <100 ms latency for voice memo capture and playback - critical for real-time UI feedback.

Equivalent & Alternatives

The following parts are listed as comparable options for similar MPEG Layer III audio decoding applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STA015T	Predecessor variant lacking MPEG-2.5 support and GPSO interface; no Joliet file system decoding.	Restricted to MPEG-1/2 only; unsuitable for 8–12 kHz low-sample-rate MP3 files or CD-ROM multimedia titles.	Select only for cost-sensitive Red Book + basic MP3 designs where MPEG-2.5 and CD-ROM features are unnecessary.
STA022T	Successor with enhanced PLL stability, lower 1.8 V core voltage, and extended −40 °C to +105 °C operating range.	Validated for under-hood automotive deployment; retains full STA016T register map and pinout compatibility.	Preferred for new designs requiring AEC-Q100 qualification or extended temperature operation beyond +85 °C.

Compared with STA015T, STA016T adds MPEG-2.5 decoding and CD-ROM firmware, enabling broader media compatibility; compared with STA022T, it lacks automotive-grade thermal margin and voltage scaling, making it suitable only for consumer-grade CD/MP3 players.

FAQ

What is the maximum supported ADPCM sampling rate and bit depth?

The STA016T supports ADPCM encoding and decoding at sampling rates from 8 kHz to 32 kHz and sample sizes from 8 bits to 32 bits. It implements DVI, ITU-T G.721, G.723-24, G.723-40, and G.726 compression standards. These parameters are configured via I²C registers I_AUDIO_CONFIG_1 through I_AUDIO_CONFIG_11 and verified in the ADPCM_CONFIGURATION register map section.

Does the STA016T require an external crystal, and what frequency is specified?

Yes, the STA016T requires an external crystal connected to XTI/XTO pins, with a nominal frequency of 14.31818 MHz as specified in the PLL_AUDIO_CONFIGURATION register documentation. This crystal feeds the internal PLL to generate precise audio clocks including OSCK and PCM_CLK, and its stability directly impacts jitter performance in the I²S output stream.

How does the CDDSP interface differ from the SDI interface in terms of data flow?

The CDDSP interface (CD_LRCK/CD_BCK/CD_SDI) carries sector-synchronized audio data from a CD servo DSP, enabling direct Red Book audio playback and MP3 decoding from CD media. The SDI interface (BS_SDI/BS_LRCK/BS_BCK) accepts generic MP3 or ADPCM bitstreams from flash memory or MCU buffers, supporting standalone file-based playback independent of physical CD mechanics.

Is the STA016T still in active production, and what is its lifecycle status?

The STA016T is marked as Obsolete Product(s) in the official STMicroelectronics documentation, with no active production or new design-in support. Aetrix Electronics maintains limited legacy stock for repair and maintenance of existing deployed systems, but recommends STA022T as the qualified drop-in replacement for new designs requiring extended temperature range and updated process technology.
