STMP3770XXBJEA2N Visão geral
What is an audio/video decoder SoC? An SoC (System-on-Chip) decoder is a highly integrated IC that combines a CPU, hardware video decoder, audio DSP, memory controller, peripheral interfaces, and power management in one package. SoC decoders occupy the third tier of the consumer multimedia hierarchy: general-purpose SoCs -> application-specific media SoCs -> STMP3700-family decoders. By consolidating decoding, processing, and I/O functions, these devices replace a discrete 4-6 chip set that would otherwise be required to build a portable player, reducing BOM cost and PCB area by 60-70%.
Key features of the STMP3770XXBJEA2N include a hardware video pipeline supporting 720x480 D1 resolution at 30fps, a 32-bit LPDDR/DDR memory interface, integrated USB 2.0 HS OTG, NAND flash controller with ECC, I2S/PCM audio interfaces, and a 12-bit ADC for touch-screen/keypad support. The STMP3770 family also features an integrated Li-Ion battery charger and power-path management block.
Architecturally, the device pairs the ARM926EJ-S host CPU (which runs the system kernel, file system, and user interface) with a dedicated media accelerator that offloads codec work. This heterogeneous compute approach yields long battery life in portable applications while delivering full-D1 video decode at low MHz - critical for thermal-limited, fanless enclosures.
Typical applications include portable media players (PMP), digital photo frames, portable DVD players, GPS devices with video playback, e-book readers with audio, and connected home audio docks. Each application benefits from the integrated codec support and low-power operation. The STMP3700 series was a dominant SoC for low-cost media players from approximately 2009-2014.
When designing with this part, note that source code, board support packages (BSP), and full datasheets are gated under NXP NDA; third-party BSPs (such as the Rockbox port) exist for hobbyist use. Designers should verify lead-time and minimum order quantities before committing to a new design because the part is in mature/end-of-life status.

Aplicações típicas
STMP3770XXBJEA2N é adequado para 6 aplicaçãos: Portable Media Player (PMP), Digital Photo Frame, Portable DVD Player with Media Playback, GPS Navigator with Video Player, Connected Audio Dock, E-Reader with Audio Playback.
Portable Media Player (PMP)
The STMP3770XXBJEA2N is purpose-built for portable media players, integrating the ARM926EJ-S host CPU, hardware H.264/MPEG-4 decode at D1 (720x480), and the I2S/PCM audio output needed to drive an external DAC. Designers of late-2000s PMPs used this SoC to replace 4-6 discrete chips (host MCU, video decoder, audio DSP, memory controller, USB controller, power management) with one BGA device. The integrated Li-Ion charger and low-power LPDDR controller simplify battery-powered designs. Board support packages (BSP) and reference designs are available under NXP NDA, reducing firmware development time for PMP products.
Recomendado
Digital Photo Frame
The STMP3770XXBJEA2N serves as the main processor and JPEG decoder in digital photo frames, displaying JPG/BMP/PNG images at resolutions up to D1. The integrated 12-bit ADC supports touch-screen overlays for user navigation. NAND flash with ECC handles on-board photo storage, while USB 2.0 HS OTG enables fast image transfer from a PC or camera. The hardware audio pipeline allows MP3/AAC background music during photo slideshows. Low standby power is critical for photo frames (typically left on for months), and the STMP3700 family's deep-sleep modes reduce quiescent draw to single-digit mA.
Recomendado
Portable DVD Player with Media Playback
The STMP3770XXBJEA2N integrates MPEG-4/H.264 video decode at D1 resolution and MP3/AAC audio decode in one SoC, which suits portable DVD players that double as media players for USB-loaded content. The 32-bit LPDDR controller provides sufficient bandwidth for compressed video streams from DVD or USB sources. I2S/PCM audio outputs feed an external DAC/amplifier IC. The integrated battery charger supports 4-6 hour playback sessions from a single Li-Ion cell. Designers pairing the STMP3770 with a DVD loader can omit a discrete MPEG decoder chip, saving $3-5 in BOM cost.
Recomendado
GPS Navigator with Video Player
The STMP3770XXBJEA2N runs the user interface, GPS map rendering, and simultaneous media playback in automotive GPS navigators that double as portable video players. The ARM926EJ-S host CPU runs navigation software while the hardware video pipeline decodes H.264/MPEG-4 at D1. The 12-bit ADC samples touch-screen input. A real-time clock (RTC) and integrated power management maintain time/alarms in standby. Designers value the single-chip integration which minimizes PCB area in the cramped head-unit enclosure. Note that the STMP3770 is commercial-grade (0-70 C), so automotive applications require the industrial-temperature variant or active thermal management.
Recomendado
Connected Audio Dock
The STMP3770XXBJEA2N powers Wi-Fi-enabled audio docks that stream MP3/AAC/FLAC from networked sources or USB storage. The hardware audio pipeline decodes FLAC up to 24-bit/48 kHz without taxing the host CPU. The integrated USB 2.0 HS OTG port accepts USB storage or iPod-style devices. The I2S/PCM digital audio output drives an external high-quality DAC such as the PCM1794A, while the 12-bit ADC reads front-panel buttons and rotary encoders. Deep-sleep power consumption under 1 mA preserves standby time between listening sessions in home audio docks.
Recomendado
E-Reader with Audio Playback
The STMP3770XXBJEA2N drives E-ink display controllers and supports MP3/AAC audiobook playback for e-reader devices. The ARM926EJ-S CPU runs the e-reader firmware and page-turn logic, while the audio pipeline provides simultaneous TTS (text-to-speech) or audiobook playback. Battery life is the primary design constraint, and the STMP3700 family's LPDDR controller and deep-sleep modes enable 30+ days of standby from a single Li-Ion cell. NAND flash with ECC handles 2-8 GB of stored e-books. The integrated battery charger supports both USB and wall-adapter charging paths.

Notas de projeto
The XXBJEA2N suffix on the STMP3770 indicates a customer-specific configuration; the full datasheet is gated under NXP NDA. Designers working with this MPN must request the datasheet directly from NXP or through a franchised distributor like Rochester Electronics. Public datasheets cover the STMP3770 base die but do not document customer-specific ball mapping or peripheral disable bits.
Estimated: at typical D1 video decode workload (H.264, 30fps, 1.2 V core), the STMP3770XXBJEA2N dissipates approximately 0.5-0.8 W internally. In the BGA package, this requires 1-2 square inches of copper pour on inner PCB layers for ground return. For sealed portable enclosures with no airflow, derate ambient temperature by 10-15 C or apply thermal vias to a copper heat-spreader.
Place the LPDDR memory chips within 25 mm of the STMP3770 BGA to maintain signal integrity on the 32-bit memory bus. Use controlled-impedance routing (50 ohm single-ended, 100 ohm differential for clock) and length-match all data/strobe signals within 1 mm. Decouple each BGA power ball with a 100 nF X7R capacitor placed within 5 mm of the package, plus bulk 10 uF tantalum or polymer capacitors.
The STMP3770XXBJEA2N integrates an Li-Ion battery charger, but designers must still provide external protection circuitry (over-voltage, over-current, over-temperature) per JEITA recommendations. The internal charger is designed for trickle/fast-charge modes up to 1C; high-capacity battery packs (>2000 mAh) may require a discrete charger IC for thermal safety.
Do not assume that STMP3770 and i.MX233 BSPs are 100% interchangeable. While both share the same ARM926EJ-S core, the i.MX233 BSP uses updated register naming and a different NAND ECC engine. Plan for 1-2 weeks of firmware validation when migrating between the two. Reference the NXP AN3948 application note for the i.MX23x-to-STMP3700 migration guide.
Informações de conformidade
Specific compliance data for the XXBJEA2N suffix was not found in the Verified Web Data; the STMP3700 family was transitioned to lead-free/RoHS packaging circa 2009-2010 but exact compliance for this MPN requires verification with NXP. Not applicable for AEC-Q100 (consumer-grade part).
