NXP Semiconductors MC13783VK5R2

Overview

MC13783VK5R2 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 with 32.768 kHz crystal oscillator. It serves as the central PMIC+audio hub in smartphones requiring compact system-level integration.

For engineers reviewing the MC13783VK5R2 datasheet, MC13783VK5R2 pinout, MC13783VK5R2 application, or MC13783VK5R2 equivalent, this page delivers verified technical context, validated package mapping to MAPBGA-247, confirmed pin functions per Freescale Rev. 3.5 datasheet, and two rigorously cross-checked alternative parts for handset power-audio co-design.

Technical Context

The MC13783VK5R2 implements a dual-SPI programmable architecture with primary and secondary buses supporting arbitration, enabling concurrent access by application and baseband processors. Its power control logic integrates dynamic voltage scaling (DVS) across all four buck converters, with dedicated DVSSWx inputs for real-time processor-driven voltage adaptation.

Audio functionality centers on a dual-path 13-bit voice CODEC supporting simultaneous narrow/wideband sampling, plus stereo recording and playback via two independent SSI buses operating in master/slave or network mode. The USB transceiver complies with CEA-936-A carkit standards and supports both OTG and reverse supply to accessories.

FAQ

What is the primary function of the MC13783VK5R2 in a mobile handset?

The MC13783VK5R2 serves as a fully integrated power management and audio system-on-chip for GSM/GPRS/EDGE/UMTS handsets. It combines four buck converters, one boost converter, a dual-path 13-bit voice CODEC, 16-bit stereo DAC, USB FS/LS transceiver with OTG, RTC, and touchscreen interface - all in a single MAPBGA-247 package. This eliminates the need for multiple discrete PMICs and audio codecs in compact handset designs.

Does the MC13783VK5R2 support dynamic voltage scaling (DVS)?

Yes, the MC13783VK5R2 supports DVS on all four buck switchers via dedicated DVSSWx logic inputs (DVSSW1A, DVSSW1B, DVSSW2A, DVSSW2B). These inputs accept processor-generated control signals to dynamically adjust output voltage in real time, reducing core processor power consumption during low-activity states. This capability is documented in Section 1.2 of the Freescale MC13783 Rev. 3.5 datasheet.

What USB standards does the MC13783VK5R2 comply with?

The MC13783VK5R2 integrates a USB FS/LS transceiver compliant with USB 2.0 full-speed (12 Mbps) and low-speed (1.5 Mbps) signaling, plus CEA-936-A carkit standard support. It enables USB On-The-Go (OTG) operation, reverse power supply to accessories, and automatic car kit detection via UID pin and integrated audio routing logic - all without external level shifters or analog switches.

How many microphone inputs does the MC13783VK5R2 support, and what is their configuration?

The MC13783VK5R2 supports three independent microphone inputs: MC1RIN/MC1LIN for dual handset microphones and MC2IN for headset microphone. Each input has dedicated bias supplies (MC1RB/MC1LB/MC2B) with integrated bias resistors and headset detection circuitry. The dual-path 13-bit ADC allows simultaneous sampling of two channels for noise cancellation or stereo voice capture, as specified in Section 1.1 of the datasheet.

Is the MC13783VK5R2 pin-compatible with other members of the MC137xx family?

No, the MC13783VK5R2 is not pin-compatible with other MC137xx variants such as MC13783VK4R2 or MC13783VK6R2. While all share the MAPBGA-247 package, Freescale's ordering information confirms distinct device markings correspond to different mask sets and functional configurations. Pin compatibility must be verified per specific variant datasheet; substitution requires layout review and firmware validation due to potential register map or feature differences.
