NXP Semiconductors MC9328MXLVM15R2

Overview

MC9328MXLVM15R2 from NXP Semiconductors (formerly Freescale) is an ARM920T™-based applications processor operating at 150 MHz, featuring integrated SDRAM controller, LCD controller, USB Device, MMC/SD host controller, and multimedia accelerator. It targets portable multimedia devices requiring low-power, high-integration SoC solutions with rich peripheral support.

For engineers reviewing the MC9328MXLVM15R2 datasheet, MC9328MXLVM15R2 pinout, MC9328MXLVM15R2 application, or MC9328MXLVM15R2 equivalent, key selection criteria include core frequency (150 MHz), 225-ball MAPBGA package, 1.7–1.9 V core voltage, integrated LCD/USB/SD interfaces, and industrial temperature range (−40°C to +85°C).

Technical Context

The MC9328MXLVM15R2 implements the ARM920T™ core with Harvard architecture, MMU, and 16 KB instruction + 16 KB data caches. Its system-level integration includes AHB-to-IP bus bridges (AIPIs), external interface module (EIM), and DPLL-based clock generation supporting dynamic power management.

It supports multiple memory interfaces: 32-bit SDRAM controller with bank/address multiplexing, 24-bit address/32-bit data EIM for NOR/NAND flash and peripherals, and dedicated controllers for LCD, USB Device (12 Mbps), MMC/SD, Memory Stick®, and CSI camera interface - all managed via configurable GPIO and signal multiplexing.

Key Specifications

Pinout & Package

MC9328MXLVM15R2 uses a 225-ball Molded Array Process Ball Grid Array (MAPBGA) package per Case 1304B-01, with 0.8 mm ball pitch and 11 × 11 array. Power delivery is partitioned across four NVDD/NVSS domains (NVDD1–NVDD4), QVDD/QVSS for core logic, and AVDD/AVSS for analog functions (e.g., USB PHY, crystal oscillator, CSI).

FAQ

What is the maximum operating frequency of the MC9328MXLVM15R2?

The MC9328MXLVM15R2 is rated for a maximum core frequency of 150 MHz. This is specified under recommended operating conditions with QVDD = 1.7–1.9 V and ambient temperature from −40°C to +85°C. The part number suffix '15' explicitly denotes the 150 MHz speed grade, distinct from the 200 MHz MC9328MXLVM20R2 variant.

Does the MC9328MXLVM15R2 support USB host functionality?

No, the MC9328MXLVM15R2 implements only USB Device 1.1 (full-speed) functionality with integrated analog transceiver. It does not support USB host or OTG modes. External USB host capability would require a companion USB host controller IC or a different i.MX variant such as the i.MX31 or later generations.

What package type and ball count does the MC9328MXLVM15R2 use?

The MC9328MXLVM15R2 uses a 225-ball MAPBGA package (Case 1304B-01) with 0.8 mm ball pitch and 11 × 11 array. This matches the 'VP' ordering designation in Table 1 of the datasheet and is physically and electrically distinct from the 256-ball 'VM' variant.

Can the MC9328MXLVM15R2 boot directly from an SD card?

Yes, the MC9328MXLVM15R2 supports SD card boot mode via its integrated MMC/SD host controller. Boot configuration is set using BOOT[3:0] pins, and the ROM bootloader can load initial firmware from SD memory cards formatted with FAT16/FAT32, enabling field-upgradable designs without external NOR flash.

What is the purpose of the QVDD and NVDD power domains on the MC9328MXLVM15R2?

The MC9328MXLVM15R2 separates power domains: QVDD/QVSS supplies the ARM920T™ core and internal logic (1.7–1.9 V), while NVDD1–NVDD4 supply I/O banks (1.7–3.3 V). This isolation prevents digital switching noise from degrading core stability and allows mixed-voltage peripheral interfacing - critical for reliable 150 MHz operation and flexible system design.
