NXP Semiconductors MC9328MXLDVM15R2

Overview

MC9328MXLDVM15R2 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 embedded systems requiring rich UI, audio playback, and low-power operation - such as digital MP3 players and handheld computers.

For engineers reviewing the MC9328MXLDVM15R2 datasheet, MC9328MXLDVM15R2 pinout, MC9328MXLDVM15R2 application, or MC9328MXLDVM15R2 equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for design-in and supply continuity.

Technical Context

The MC9328MXLDVM15R2 implements a 32-bit ARM920T core with Harvard architecture, 16 KB instruction and 16 KB data caches, and MMU support. Its memory subsystem includes a 32-bit SDRAM controller supporting up to 256 MB, configurable external bus interface (EIM), and dual chip-select banks for NAND/NOR flash and peripherals.

Peripherals are tightly coupled via AHB-to-IP bus interfaces (AIPIs): the LCD controller supports 16-bit RGB/TFT panels with programmable scan direction; the USB Device complies with USB 2.0 full-speed (12 Mbps); and the MMC/SD host controller supports SD v1.1 and MMC v3.31 protocols with 4-bit data width.

Key Specifications

Pinout & Package

MC9328MXLDVM15R2 is housed in a 225-ball MAPBGA (Case 1304B-01), with 11 × 11 array, 0.8 mm pitch, and 1.2 mm height. Power domains include QVDD/QVSS (core), NVDD1–NVDD4/NVSS (I/O groups), AVDD/AVSS (analog), and QVDD3/QVDD4 (internal logic). Ball assignments follow Freescale's signal multiplexing scheme with primary and alternate functions per pin.

FAQ

What is the maximum SDRAM capacity supported by the MC9328MXLDVM15R2?

The MC9328MXLDVM15R2 SDRAM controller supports up to 256 MB using 16-Mbit × 16-bit devices in non-interleave mode. Bank addressing uses SDBA[4:0], and row/column selection is handled via MA[11:0] and DQM[3:0]. Configuration is performed through the SDRAM Control Register (SDRAMC_CR) in the system control module. The MC9328MXLDVM15R2 datasheet specifies timing parameters for 100 MHz SDRAM clocks with tRCD = 20 ns and tRP = 20 ns.

Does the MC9328MXLDVM15R2 support USB host functionality?

No, the MC9328MXLDVM15R2 integrates only a USB 2.0 full-speed device controller (USBD_VP/VM signals), not a host controller. It can act as a peripheral (e.g., mass storage device or CDC ACM) when connected to a PC or host system. USB host capability requires external PHY and hub logic or migration to later i.MX families like i.MX27 or i.MX31, which include OTG or dual-role controllers.

What is the purpose of the BOOT[3:0] pins on the MC9328MXLDVM15R2?

The BOOT[3:0] pins (AVDD1-supplied inputs BOOT03–BOOT33) determine the system boot source and configuration after reset. Their logic levels select between internal ROM boot, external NOR/NAND flash, or SD/MMC card boot modes. For example, BOOT[3:0] = 0b0010 configures boot from CS0-connected NOR flash. These pins must be stable before release of RESET_IN and remain unchanged during operation.

Can the MC9328MXLDVM15R2 drive a 24-bit RGB LCD panel?

No - the MC9328MXLDVM15R2 LCD controller outputs only 16-bit RGB (LD[15:0]) with fixed pixel format. It does not support 24-bit (RGB888) panels natively. To interface with 24-bit displays, external LVDS or RGB-to-24-bit bridge ICs (e.g., THCV216) are required. The controller supports programmable polarity, HSYNC/VSYNC timing, and Sharp-panel-specific signals (SPL_SPR, PS, CLS) for direct TFT integration.

Is the MC9328MXLDVM15R2 pin-compatible with the 256-ball MAPBGA variant (e.g., MC9328MXLVM15R2)?

No - the MC9328MXLDVM15R2 (225-ball MAPBGA) and MC9328MXLVM15R2 (256-ball MAPBGA) have different ball counts, layouts, and signal mappings. Table 1 in the datasheet confirms distinct ordering numbers and package types. Pin compatibility is not claimed; PCB redesign is required when migrating between 225- and 256-ball variants due to differing power domain assignments and peripheral signal locations.
