Product details
Overview
MC9328MXLCVM15 from Freescale Semiconductor is an ARM920T™-based applications processor operating at 150 MHz, packaged in a 225-ball MAPBGA (Case 1304B-01), with integrated LCD controller, USB Device, MMC/SD host, SDRAM controller, and dual UARTs - designed for portable multimedia devices requiring low-power operation across –40°C to +85°C industrial temperature range.
For engineers reviewing the MC9328MXLCVM15 datasheet, MC9328MXLCVM15 pinout, MC9328MXLCVM15 application, or MC9328MXLCVM15 equivalent, key selection considerations include its 150 MHz core frequency, 225-ball MAPBGA package, industrial temperature rating, integrated multimedia peripherals, and power supply requirements (QVDD: 1.7–1.9 V, NVDD: 1.7–3.3 V).
Technical Context
The MC9328MXLCVM15 implements the ARM920T™ core with Harvard architecture, MMU, and 16 KB instruction + 16 KB data caches. Its system-level integration includes an External Interface Module (EIM) supporting NOR/NAND flash and SRAM, a 32-bit SDRAM controller with bank addressing, and clock generation via DPLL with multiple output dividers.
Peripherals are connected through AHB-to-IP Bus Interfaces (AIPIs), enabling concurrent access to LCD controller, USB device, DMA, and multimedia accelerators. The processor supports boot from NAND flash, NOR flash, or serial ROM via BOOT[3:0] configuration, with flexible I/O voltage grouping (NVDD1–NVDD4, AVDD, QVDD) enabling mixed-signal interface design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| i.MX21ADS (MC9328MX21ADS) | ARM926EJ-S core @ 266 MHz, 256-pin MAPBGA, adds JPEG encoder, security engine, and enhanced USB OTG | Higher performance, richer multimedia acceleration, but larger package and higher power draw | Select when JPEG encode/decode or secure boot is required; not drop-in due to pinout and power sequencing differences |
| MC9328MXLVP15(R2) | Same ARM920T core @ 150 MHz, identical peripheral set, but rated for 0°C to 70°C commercial temperature range and 225-ball MAPBGA | Lower cost and qualification level; unsuitable for extended temperature environments | Choose for cost-sensitive consumer applications where industrial temp grade is unnecessary |
Compared with MC9328MXLCVM15, i.MX21ADS offers higher compute density and hardware-accelerated codecs but requires layout redesign and thermal revalidation, while MC9328MXLVP15 provides identical functionality at lower qualification cost - making MC9328MXLCVM15 the optimal choice for thermally demanding industrial deployments.

FAQ
What is the maximum operating frequency of the MC9328MXLCVM15?
The MC9328MXLCVM15 operates at a maximum core frequency of 150 MHz. This frequency is guaranteed across its full industrial temperature range (–40°C to +85°C) and specified core supply voltage (QVDD = 1.7 V to 1.9 V). It is distinct from the 200 MHz variant (e.g., MC9328MXLCVM20), which requires higher QVDD (1.8–2.0 V) and is not supported by this specific ordering part number.
Does the MC9328MXLCVM15 support boot from NAND flash memory?
Yes, the MC9328MXLCVM15 supports NAND flash boot via its External Interface Module (EIM) and dedicated NAND controller logic. Boot mode is selected using BOOT[3:0] pins; NAND boot requires BOOT[3:0] = 0b0010. The processor includes hardware ECC generation and correction circuitry compatible with standard SLC NAND devices, eliminating the need for external ECC logic.
What are the power supply requirements for the MC9328MXLCVM15?
The MC9328MXLCVM15 requires four independent supply domains: QVDD (1.7–1.9 V) for the ARM920T™ core, NVDD1–NVDD4 (1.7–3.3 V) for grouped I/O banks, AVDD (1.7–3.3 V) for analog peripherals (USB, ADC, crystal drivers), and QVSS/NVSS/AVSS grounds. Each domain must be decoupled per Freescale's AN2537 power sequencing guidelines to ensure reliable startup and noise immunity.
Can the MC9328MXLCVM15 drive a 24-bit RGB LCD panel directly?
No, the MC9328MXLCVM15's LCD controller outputs LD[15:0], providing only a 16-bit data bus. It supports 16-bit RGB (565 format) or 16-bit CPU interface (e.g., for Sharp HR-TFT panels), but cannot natively drive 24-bit RGB (888) panels. To interface with 24-bit displays, an external LVDS or RGB serializer IC (e.g., THCV216) is required to expand the data path and manage timing.
Is the MC9328MXLCVM15 pin-compatible with other i.MX processors like the i.MX27 or i.MX31?
No, the MC9328MXLCVM15 is not pin-compatible with later i.MX generations. It uses a proprietary 225-ball MAPBGA footprint (Case 1304B-01) with unique ball assignment and power domain grouping. Migration to i.MX27 or i.MX31 requires complete PCB redesign due to differences in package size, ball count (e.g., i.MX27 uses 400-ball PBGA), signal mapping, and power architecture.
