What are the key features of STA013?
- Full MPEG-1 and MPEG-2 Layer I/II/III (MP3) software decoding on a dedicated DSP core running at up to 3.6 V supply for consumer audio players
- I2S serial audio output interface directly drives external DACs and audio codecs without additional glue logic
- Compact SO-28 (R-PDSO-G28) package integrates the complete MP3 decode pipeline in a single 28-pin IC, minimizing external component count in portable audio designs
What is STA013 used for?
STA013 is designed for portable MP3 players, internet radio receivers, and car audio head units that require full MPEG Layer I, II, and III decoding at 3.6 V supply without a general-purpose CPU handling audio processing. Its I2S output connects directly to a stereo DAC such as CS4334 or PCM1716 to reproduce 32 kHz, 44.1 kHz, or 48 kHz audio streams with minimal firmware overhead. The device also fits home audio docking stations and low-power audio modules where a single-function decoder IC reduces bill-of-materials cost compared to a DSP-based solution.

Frequently Asked Questions
What MPEG audio standards and sample rates does STA013 support?
STA013 decodes MPEG-1 and MPEG-2 Layer I, II, and III (MP3) bitstreams at standard sample rates of 32 kHz, 44.1 kHz, and 48 kHz, as well as MPEG-2.5 extensions down to 8 kHz, supporting bit rates from 8 kbps to 320 kbps to cover both voice-quality and CD-quality audio content.
How does the I2S interface on STA013 connect to an external DAC without additional logic?
STA013 outputs decoded audio over a standard I2S serial bus with a word-clock (LRCK), bit-clock (BCLK), and serial data line (SDATA) that are directly compatible with popular stereo DACs operating at 3.3 V; no level shifter or glue logic is needed when the DAC's I2S input thresholds align with the 3.6 V logic levels of STA013, reducing the PCB component count by 3–5 passive components.
What supply voltage does STA013 require, and is it compatible with lithium-ion battery-powered designs?
STA013 operates from a maximum supply of 3.6 V, which is compatible with a single lithium-ion cell (3.0 V to 4.2 V) when used with a low-dropout regulator set to 3.3 V, making it practical for portable MP3 players and wireless audio streamers that run from a 700 mAh or larger LiPo cell.
For a portable audio player PCB, how does the SO-28 package of STA013 affect board layout?
The SO-28 (R-PDSO-G28) package has a 1.27 mm pitch and a body size of approximately 17.9 mm × 7.5 mm, which occupies less than 135 mm² on the PCB and fits a standard 28-pin SOIC land pattern, allowing designers to use a pre-characterized footprint from most EDA libraries and route audio and control signals on a 2-layer board.
When should STA013 be chosen over a software-decode solution running on a microcontroller?
STA013 is chosen when real-time MP3 decode at 320 kbps is required and the host MCU lacks sufficient MIPS — typically under 80 MHz ARM Cortex-M0 — to decode audio in software while also managing display, user input, and communication; offloading decode to STA013 frees over 90% of CPU cycles and reduces firmware complexity to a simple I2C or SPI control interface plus 3-wire I2S audio output.
