An applications processor (AP) is a system-on-chip (SoC) class microprocessor that integrates a CPU core, memory controllers, and peripheral IP blocks so a portable product can be built with minimal external logic. The MC9328MXL belongs to the hierarchy ARM core -> ARM9 family -> ARM920T -> i.MX -> i.MXL applications processor -> embedded multimedia MPU, sitting at the apex of NXP's low-power multimedia line for handheld and portable designs.
Key features of the MC9328MXLVM15 include an ARM920T core with 16 KB instruction cache and 16 KB data cache, a 128-bit external memory bus supporting SDRAM, NOR/NAND flash, and PCMCIA/CF cards, an integrated LCD controller capable of driving STN and TFT panels, a USB 1.1 device port, an MMC/SD host controller, and serial interfaces including UART, SPI, I2C, and I2S. Operating voltages are split between a 1.8V core supply and 3.0V I/O supply, with industrial-grade temperature options in the family.
Architecturally, the ARM920T core implements the ARMv4T instruction set with a five-stage pipeline and separate instruction/data caches backed by a write buffer. The integrated LCD controller supports up to 800x600 resolution in passive color mode, and the system bus uses a multi-layer AHB fabric to keep peripheral DMA traffic from starving the CPU. Compared with the i.MX1 (MC9328MX1), the i.MXL family retains the same ARM920T core but typically ships at lower clock speeds and slightly different peripheral mixes.
Typical applications for the MC9328MXLVM15 include portable media players, PDAs, smart handhelds, GPS navigators, industrial HMI panels, and early-generation e-readers. The on-chip LCD controller and SDRAM interface let engineers build a complete graphics terminal with only a power management IC, panel, and touch controller as external components.
When designing with this part, ensure the 1.8V core and 3.0V I/O rails are brought up in the correct sequence to avoid latch-up, and place the boot-mode strapping resistors exactly as NXP specifies. Because the part is now end-of-life, consider long-term availability and second-source risk before committing new designs.

典型應用
MC9328MXLVM15 適用於 8 應用s: Portable Media Player, Personal Digital Assistant (PDA), GPS Navigator, Industrial HMI Panel, Early-Generation E-Reader, Smart Handheld Terminal, Set-Top Box Auxiliary Controller, Educational / Developer Handheld.
Portable Media Player
The MC9328MXLVM15 is a strong fit for portable media players because its integrated LCD controller drives STN/TFT panels up to VGA class without an external graphics chip, while the ARM920T core at 150 MHz decodes MP3 and early-generation MPEG-4 streams with cycles to spare for UI rendering. The on-chip USB 1.1 device port enables drag-and-drop file transfers from a PC, and the MMC/SD host controller accepts the storage cards users expect in this category. The 1.8V core and 3.0V I/O split keeps total power low enough for Li-ion battery operation, with measured quiescent draw in the deep-sleep mode suitable for week-long standby. Engineers typically pair this MPU with a small PMIC, a 320x240 TFT, and 16-32 MB of SDRAM to ship a complete PMP reference design.
推薦
Personal Digital Assistant (PDA)
PDAs of the early-to-mid 2000s relied on the MC9328MXLVM15 because its 16 KB instruction cache and 16 KB data cache plus write buffer kept the ARM920T responsive even when running Palm OS or early Windows CE builds with background sync. The 128-bit external memory bus connects directly to SDRAM and PCMCIA/CF cards, so designers can add Wi-Fi or memory expansion without extra glue logic. The integrated LCD controller handles both monochrome reflective and color TFT panels, which is critical for the long battery-life PDA segment. Typical designs pair this processor with 32-64 MB SDRAM, a 3.5-inch 240x320 panel, and a touchscreen controller on the SPI bus for stylus input.
推薦
GPS Navigator
Automotive and handheld GPS navigators in the 2003-2007 generation used the MC9328MXLVM15 as the main application processor because its LCD controller could drive 480x272 TFT panels required for car-mount displays while leaving CPU cycles for map rendering, route calculation, and GPS sentence parsing. The 150 MHz ARM920T runs typical map engines at acceptable frame rates, and the MMC/SD host controller accepts the geo-data cards common in this segment. The 3.0V I/O ring simplifies interfacing to GPS receiver modules that often operate at 3.3V with minor level shifting. Designers typically add a separate GPS baseband chip, 32-64 MB SDRAM, and a 4-wire resistive touchscreen controller.
推薦
Industrial HMI Panel
The MC9328MXLVM15 suits industrial HMI panels because its integrated peripherals - LCD controller, UART, SPI, I2C - let a single chip drive a touch panel, talk to a PLC, and expose diagnostic LEDs without an external companion MCU. The ARM920T core at 150 MHz runs typical HMI stacks (Qt/Embedded, WinCE) with enough headroom for graph redraws and alarm logging. Its commercial temperature grade (per VM15 suffix) covers most factory-floor enclosures; designers needing wider ranges should consider the CVP15 variant. A typical reference design pairs this MPU with 32 MB SDRAM, 16 MB NOR flash, and an isolated RS-485 transceiver on UART1 for PLC comms.
推薦
Early-Generation E-Reader
First-generation e-readers that used STN LCD panels (rather than E-Ink) often paired the MC9328MXLVM15 with a 640x480 monochrome display because the on-chip LCD controller and 150 MHz ARM920T gave just enough bandwidth for slow page-turn animations and bookmark refresh. The split 1.8V/3.0V supply keeps average power low during the long static-page display phase, since most of the budget is consumed by panel refresh rather than compute. Typical designs add 16 MB SDRAM, 8 MB NOR flash for fonts, and an MMC slot for sideloaded content.
推薦
Smart Handheld Terminal
Warehouse and field-service smart terminals in the mid-2000s used the MC9328MXLVM15 because its LCD controller, USB device port, and UART/SPI/I2C mix let one chip handle a small TFT, a barcode scanner module, and a wireless modem without an external bridge. The ARM920T core runs terminal emulators and inventory software with enough margin for encryption and CRC calculations on barcode scans. Industrial temperature variants (CVP15 suffix) extend operation to freezer and outdoor environments, while the 256-ball MAPBGA package survives the vibration profiles typical of handheld use.
推薦
Set-Top Box Auxiliary Controller
Some early digital set-top boxes used the MC9328MXLVM15 as an auxiliary front-panel controller because its LCD controller drives small character or graphic displays, the I2S interface routes digital audio, and the MMC/SD host controller accepts conditional-access cards. The 150 MHz ARM920T handles on-screen display overlays, parental-control menus, and standby-mode housekeeping without burdening the main media processor. Designers typically pair this MPU with 16 MB SDRAM, 4 MB NOR flash, and a small character LCD or low-res TFT.
推薦
Educational / Developer Handheld
Educational programming handhelds and developer kits favored the MC9328MXLVM15 because the ARM920T core is fully documented and supported by GCC, IAR, and Keil toolchains, while the on-chip peripherals give students one chip to learn drivers for. The 256-ball MAPBGA exposes a wide bus for SDRAM expansion in lab exercises, and the integrated LCD controller eliminates the need for an external graphics chip during early bring-up. Many university and hobbyist designs add a small TFT, a 4x4 keypad on the GPIO, and 32 MB SDRAM to keep the BOM under $30.

設計說明
Estimated: at core 1.8V @ 150 MHz pulling ~150 mA and I/O 3.0V @ 50 mA, the MC9328MXLVM15 dissipates roughly 0.42 W under typical multimedia load, so a small LDO pair (one for VDD, one for VDDIO) is sufficient. Bring the 1.8V core rail up before or simultaneously with the 3.0V I/O rail; reverse sequencing can latch the I/O cells. Decouple each VDD/VSS pair with a 100 nF X7R placed within 2 mm of the ball, plus a bulk 10 uF tantalum near the package.
The 256-ball MAPBGA uses a 0.8 mm ball pitch, so PCB design requires 0.4 mm laser-drilled micro-vias, 4 mil trace/spacing, and a solder mask registration of 2 mil to avoid solder bridging during reflow. Use NSMD (non-solder-mask-defined) pads with a 0.35 mm solder-mask opening to maximize the standoff and improve self-alignment during reflow. Match the BGA pad diameter to NXP case 1304B-01 recommendation (typically 0.45 mm pad on a 0.8 mm pitch).
Because the MC9328MXLVM15 is end-of-life, sourcing risk is the #1 pitfall: do not commit to a production design without securing a last-time-buy. Other common pitfalls include leaving boot-mode strapping resistors unpopulated (the chip will boot from the wrong device), routing the LCD data bus across noisy power layers (causes panel flicker), and failing to add a watchdog timer on the reset supervisor (an ARM9 lockup will freeze the panel indefinitely).
The 256-ball MAPBGA has a theta_JA of approximately 35 C/W on a 4-layer JEDEC test board, which gives a junction-to-ambient rise of about 15 C at 0.42 W typical dissipation. Add a thermal pad pattern under the BGA center and stitch vias to the inner ground plane to drop the effective theta_JA further; this is recommended but not critical for the commercial temperature grade.
The 128-bit external memory bus runs at up to 96 MHz, so route SDRAM traces with controlled impedance (50 ohm single-ended), keep trace lengths matched within 25 mils on byte lanes, and place a 33 ohm series damping resistor near the driver when crossing more than two discontinuities. Series damping on the clock and DQS lines is especially important to suppress overshoot that can corrupt SDRAM reads.
