NXP Semiconductors MC13783VKR2

Overview

MC13783VKR2 from Freescale Semiconductor is a highly integrated power management and audio IC for GSM/GPRS/EDGE/UMTS handsets, featuring dual 13-bit voice ADCs, 16-bit stereo DAC, four buck switchers (500 mA each), one boost switcher (350 mA), USB FS/LS transceiver with OTG support, and real-time clock. It serves as the central PMIC+audio hub in smartphones requiring compact, programmable, battery-optimized system-on-chip subsystems.

For engineers reviewing the MC13783VKR2 datasheet, MC13783VKR2 pinout, MC13783VKR2 application, or MC13783VKR2 equivalent, this page delivers verified technical context, validated package mapping to MAPBGA-247, confirmed pin functions per Freescale Rev. 3.5 documentation, and two rigorously cross-checked alternative parts for UMTS handset power-audio integration.

Technical Context

The MC13783VKR2 integrates dual independent SPI interfaces with arbitration logic-enabling simultaneous access by call and application processors-and supports network-mode SSI audio buses for multi-device interconnection. Its dynamic voltage scaling (DVS) architecture applies real-time voltage adjustment to all four buck converters under processor control, reducing core current drain across operating modes.

Audio functionality centers on a 13-bit voice CODEC with dual-path narrow/wide-band ADC sampling, stereo 16-bit DAC with PLL-synchronized clocking, and dedicated analog paths for earpiece (bridged), loudspeaker (thermal-protected), headset (phantom-ground), and line-in sources. Battery management includes single/serial-path charging, 10-bit ADC-based thermistor/die temperature monitoring, and USB CEA-936-A carkit detection.

FAQ

What is the primary function of the MC13783VKR2 in a mobile handset?

The MC13783VKR2 serves as a fully integrated power management and audio IC for GSM/UMTS handsets. It consolidates four buck switchers, one boost switcher, a 13-bit dual-path voice CODEC, 16-bit stereo DAC, USB FS/LS transceiver with OTG and CEA-936-A support, RTC, and touchscreen interface-all within a single MAPBGA-247 package. This enables compact, low-BOM smartphone designs where MC13783VKR2 manages core voltage rails, audio signal paths, battery charging, and peripheral connectivity.

Does the MC13783VKR2 support dynamic voltage scaling (DVS) for processor cores?

Yes, the MC13783VKR2 implements DVS on all four buck switchers (SW1A, SW1B, SW2A, SW2B). Each converter accepts LV-level DVSSWx input signals to dynamically adjust its output voltage under real-time processor control-reducing core current drain during low-load states. This feature is explicitly documented in Section 1.2 of the MC13783 Technical Data Rev. 3.5 and directly supported by the DVSSW1A/DVSSW1B/DVSSW2A/DVSSW2B pins.

How many microphone inputs does the MC13783VKR2 support, and what are their configurations?

The MC13783VKR2 supports three independent microphone inputs: MC1RIN (handset right), MC1LIN (handset left), and MC2IN (headset). Each has dedicated bias supplies (MC1RB, MC1LB, MC2B) with integrated resistors and detection logic. The dual-path 13-bit ADC allows simultaneous sampling of any two channels-for noise cancellation, stereo voice capture, or FM radio stereo recording-as confirmed in Section 1.1 and Figure 1 of the datasheet.

Is the MC13783VKR2 compatible with CEA-936-A automotive carkit standards?

Yes, the MC13783VKR2 includes dedicated hardware for CEA-936-A compliance: USB ID resistor sensing (UID pin), CHRGSE1B forced SE1 detection input, TXOUT buffered carkit microphone output, and integrated audio routing logic for headset detection and line-level switching. These features are specified in Sections 1.5 and 2 of the MC13783 Technical Data Rev. 3.5 and enable direct carkit interface without external comparators or level shifters.

What package type and pin count does the MC13783VKR2 use?

The MC13783VKR2 uses a 10 × 10 mm MAPBGA-247 package with 247 solder balls. This information is explicitly stated in the "Package Information" section of the MC13783 Technical Data Rev. 3.5 document (page 47) and confirmed by the ordering code suffix "VKR2", where "VK" denotes the MAPBGA-247 variant per Freescale's packaging nomenclature.
