NXP Semiconductors MC13892CJVK

Overview

MC13892CJVK from NXP Semiconductors (formerly Freescale) is a Power Management Integrated Circuit (PMIC) engineered for i.MX35 and i.MX51 application processors. It integrates four adjustable buck regulators (up to 1050 mA), twelve LDOs, a 300 mA boost regulator, 10-bit ADC with coulomb counter, RTC with coin-cell backup, touch screen interface, and SPI/I²C control - all in a 139-pin 7×7 mm BGA package. It powers netbooks, smart mobile devices, and portable navigation systems.

For engineers reviewing the MC13892CJVK datasheet, MC13892CJVK pinout, MC13892CJVK application, or MC13892CJVK equivalent, this page delivers verified specifications, validated pin functions per the VK suffix package, confirmed thermal ratings (−40°C to +85°C), exact regulator output ranges (e.g., VCORE: 0.6–1.375 V), and real-world integration context with i.MX processors and USB/LED/backlight subsystems.

Technical Context

The MC13892CJVK implements a multi-rail power architecture with four independent buck switchers (SW1–SW4), each supporting PWM and PFM modes, programmable DVS inputs (DVS1/DVS2), and dedicated feedback pins (e.g., SW1FB, SW2FB). Its SMARTMOS process enables integrated battery charging (wall/USB), coulomb counting via BATTISNSCC/CFP/CFM, and precision RTC operation powered by either BP or LICELL.

Control is handled through a dual-interface SPI/I²C bus (CS/CLK/MOSI/MISO, optional I²C decode), with interrupt-driven event handling (INT pin), watchdog input (WDI), and configurable power-up sequencing via PUMS1/PUMS2. The device includes dedicated analog blocks: 10-bit ADC with seven channels (ADIN5–ADIN7, BATTISNS, CHRGISNS), touch screen interface (TSX1/TSX2/TSY1/TSY2/TSREF), and RGB/Keypad LED drivers (LEDR/LEDB/LEDG/LEDKP/LEDMD).

Key Specifications

FAQ

What is the maximum continuous load current supported by the SW1 buck regulator in the MC13892CJVK?

The MC13892CJVK SW1 buck regulator supports a maximum continuous load current of 1050 mA in PWM mode when SWILIMB = 0. In PFM mode, its maximum continuous load is 50 mA. This specification is defined in Table 5 of the MC13892 Rev. 19.0 datasheet under "BUCK REGULATORS" - confirming SW1's role as the primary core supply for i.MX processors requiring high-current, low-voltage rails.

Does the MC13892CJVK include an integrated real-time clock with battery backup capability?

Yes, the MC13892CJVK integrates a complete RTC subsystem with dedicated VSRTC output (1.15–1.25 V), 32.768 kHz crystal oscillator circuitry (XTAL1/XTAL2), and coin-cell backup support via the LICELL pin. When main battery power is absent, the RTC continues operating from the coin cell - a feature confirmed in the "Features" section and Electrical Characteristics tables of the MC13892 datasheet.

How many ADC input channels does the MC13892CJVK provide, and what is their resolution?

The MC13892CJVK includes a 10-bit successive-approximation register (SAR) ADC with seven configurable input channels: ADIN5, ADIN6, ADIN7, BATTISNS, CHRGISNS, TSREF, and internal die temperature sensor. This is explicitly stated in the "Features" list and verified in Table 2 (Pin Definitions) and Table 5 (Static Electrical Characteristics) of the MC13892 Rev. 19.0 datasheet.

What communication interfaces are supported by the MC13892CJVK for register configuration and control?

The MC13892CJVK supports both SPI and I²C interfaces for register access and configuration. Primary control uses a 4-wire SPI interface (CS, CLK, MOSI, MISO) with optional I²C decode enabled at boot via MODE pin configuration. This dual-interface capability is documented in the "Features" section and functional pin definitions (e.g., CS, CLK, MOSI, MISO, MODE) of the MC13892 datasheet.

Is the MC13892CJVK pin-compatible with other variants in the MC13892 family, such as MC13892DJVK?

The MC13892CJVK shares identical pinout and package (139-pin 7×7 mm BGA) with MC13892DJVK and MC13892AJVK, as confirmed in Table 1 ("Device Variations") of the MC13892 datasheet. All VK-suffix parts use the same Figure 3 pin map - differing only in factory-programmed reset behavior (Global Reset Default ON vs. OFF), not physical connectivity or electrical function.
