N.º de pieza: MC9328MX1VH20 ✗ Fin de vidaMC9328MX1VH20 Descripción general
An ARM920T processor is a 32-bit RISC CPU core combining an integer core, separate 16 KB instruction and 16 KB data caches, a Memory Management Unit (MMU) for virtual memory and protected operating systems, and an AMBA bus interface. The i.MX1 (MC9328MX1) is one of the first "application processors" built on the ARM9 family from Freescale/NXP, designed as a system-on-chip for handheld and portable devices. It belongs to the application processor > microprocessor > SoC > semiconductor hierarchy, and is part of the historically important Dragonball-lineage MX family that bridged early PDA devices into modern smartphone-era silicon.
Key features include ARM920T core with MMU, hardware-based LCD controller supporting STN and TFT panels, USB 1.1 full-speed device and host interfaces, integrated memory and PCMCIA/CompactFlash controllers, I2C, SPI, UART, SSI/I2S audio interfaces, and PWM timers. The integrated peripherals removed the need for external companion chips, reducing BOM cost and board area in portable designs.
The architecture combines a 200 MHz ARM920T core with an AHB system bus, peripheral bus bridge, DMA controller, and a rich set of on-chip peripherals clocked from a configurable PLL. Boot modes select from external 16-bit ROM/Flash or internal bootstrap ROM. The MMU enables full Linux and WinCE operating system support, a notable capability for 2003-era embedded silicon.
Typical applications include portable media players, PDAs, industrial handhelds, early smart appliances, and embedded Linux prototypes. The integrated LCD controller makes it well-suited for graphical HMI panels, while USB host enables keyboard, mouse, and mass-storage connectivity.
When designing with this part, plan the PCB stack-up for a 14x14 mm fine-pitch BGA with controlled-impedance traces to the external SDRAM bus. Decouple each power domain with bulk and high-frequency ceramic capacitors placed as close as possible to the balls, and provide a properly filtered 32.768 kHz clock for the real-time clock domain.

Aplicaciones típicas
MC9328MX1VH20 es adecuado para 6 aplicacións: Portable Media Player (PMP) Main Processor, Industrial Handheld Terminal / PDA, Embedded Linux Graphical HMI Panel, Set-Top Box Auxiliary Processor, Medical Data-Logger / Tablet Accessory, Telematics / Fleet-Mounted Black-Box Telemetry.
Portable Media Player (PMP) Main Processor
The MC9328MX1VH20 is well-suited as the main application processor in mid-2000s portable media players because the i.MX1 integrates an ARM920T core running at 200 MHz together with a hardware TFT/STN LCD controller, an SSI/I2S digital audio interface, USB 1.1 device and host ports, and an external SDRAM/Flash memory bus - eliminating the need for external companion chips. The integrated LCD controller with hardware-accelerated color space conversion drives 320x240 to 640x480 panels commonly used in PMP products of the era. Designers can connect a Wolfson or AKM audio codec directly via SSI/I2S to get 44.1 kHz stereo playback without an external DSP. The SDRAM bus drives up to 128 MB external memory for video buffering, while the MMU enables a Linux port for menu navigation and codec dispatch. Use this part for legacy PMP refresh designs; new designs should consider i.MX RT series for power efficiency.

Industrial Handheld Terminal / PDA
Industrial handheld terminals benefit from the MC9328MX1VH20 because the part integrates a full MMU (enabling protected WinCE or Linux), a 200 MHz ARM920T integer pipeline, and a hardened peripheral set including UART, SPI, I2C, GPIO and a PCMCIA/CF controller. The 256-MAPBGA footprint supports -40C to +85C operation for factory-floor deployments. The LCD controller drives sunlight-readable resistive touch TFT panels via SPI on the touchscreen controller side. USB host enables barcode scanner and RFID reader expansion, while PCMCIA enables industrial radio modules (Wi-Fi 802.11b, GSM/GPRS modems) of that era. For greenfield industrial PDAs, designers should validate against modern equivalents, but for sustaining legacy installations the MC9328MX1VH20 remains a viable choice. Power management requires a PMIC with explicit attention to core 1.8V and I/O 3.3V rails.
Recomendado
Embedded Linux Graphical HMI Panel
Graphical HMI panels in industrial control and home automation benefit from the MC9328MX1VH20 because the 200 MHz ARM920T with MMU runs full embedded Linux distributions while the integrated TFT/STN LCD controller drives QVGA to VGA panels natively. The SSI/I2S peripheral streams pre-recorded voice prompts or alarm tones, while the USB host port accepts keyboards, mice and USB mass-storage for firmware updates. Two UARTs enable fieldbus integration (Modbus, DMX512, or legacy RS-485 bridges) and the SD/MMC controller enables local logging. The 256-MAPBGA package is well-suited to a 4-6 layer industrial-grade PCB with conformal coating. A Qt/Embedded or GTK+/DirectFB application layer uses the MMU for protected-mode graphics, and the SPI bus drives capacitive touch controllers. Design tip: route the SDRAM clock net 50 ohm controlled-impedance with length-matched DQS.

Set-Top Box Auxiliary Processor
The MC9328MX1VH20 can serve as the user-interface and front-panel controller in legacy set-top boxes thanks to its 200 MHz ARM920T core, integrated LCD controller for front-panel displays, USB host for Wi-Fi dongles and external storage, and I2S/SSI for digital audio to an external DAC. The MMU enables a Linux port for rendering EPG (electronic program guide) and on-screen overlays. UART and SPI ports communicate with the main MIPS or ARM SoC carrying transport-stream demodulation. Designers can pair the i.MX1 with an NXP TDA series tuner for hybrid application. For new designs NXP strongly prefers i.MX 6ULL/i.MX RT series, but the i.MX1 remains viable for sustaining production of legacy STB models where tens of millions of units still ship annually in emerging markets.
Recomendado
Medical Data-Logger / Tablet Accessory
Medical data-acquisition accessories benefit from the MC9328MX1VH20 because the part offers a 200 MHz ARM920T core with MMU (enabling WinCE for medical UI work), USB device port for tethered upload to a host tablet, UART/SPI/I2C interfaces for sensor modules (temperature, SpO2, ECG front-ends), and a real-time clock with watchdog for safe state retention. The integrated LCD controller drives a 320x240 panel showing real-time waveforms, eliminating the need for a graphical companion chip. USB host port enables bar-code scanner add-ons for asset tracking. SDRAM bus connects 64-128 MB external memory for local buffering of patient data. Designers should pair the i.MX1 with an external galvanic-isolated interface because the i.MX1 itself is not a medical-grade front-end.
Recomendado
Telematics / Fleet-Mounted Black-Box Telemetry
The MC9328MX1VH20 fits vehicle-mounted telematics black-boxes due to its industrial temperature range, ARM920T core with MMU running Linux or RTOS, USB host for GPS dongles, UART for CAN-bridge or OBD-II interface ICs, and SD/MMC controller for mass-storage of telemetry logs. The integrated LCD controller can drive a small status panel for driver feedback. The 256-MAPBGA package tolerates vibration when properly board-mounted to a chassis or enclosure. PCMCIA or SD card slots capture long-term logs. Power management requires a wide-input automotive regulator: the i.MX1 runs on 3.3V I/O plus internal core rail. Note that this part is NOT AEC-Q100 qualified; designers must verify vibration and thermal compliance for automotive applications using external qualification evidence.

Notas de diseño
The 256-MAPBGA (14x14 mm) on the MC9328MX1VH20 typically uses a 0.8 mm or 1.0 mm ball pitch. Use a 4-to-6 layer PCB stack-up with at least two dedicated ground planes directly under the BGA. Escape inner-row balls with laser-drilled microvias (0.1 mm) to inner signal layers. Match length on the SDRAM clock, DQS and data/address lanes to within 50 ps for stable external memory access, per the NXP MC9328MX1 hardware design guide.
Estimated: total power consumption for the MC9328MX1VH20 at 200 MHz core clock with full peripheral activity is in the 500 mW to 900 mW range based on NXP datasheet typical operating currents; verify with the latest datasheet before final BOM. Bulk-decouple each VDD rail with a 22 microfarad tantalum or polymer plus a 0.1 microfarad ceramic placed within 2 mm of each ball row. Use a star-ground topology that returns digital ground currents directly to the lowest-impedance plane without crossing analog sections.
On the MC9328MX1VH20, the BOOT configuration pins are sampled only at reset; failing to drive them to a known state with pull resistors during pow er-up can leave the part in an undefined boot mode and cause hidden flash-programming failures. Use 10 kilo-ohm pull-ups or pull-downs as appropriate for the desired boot source, and do not share these pins with high-speed signals during reset. Also ensure the RT32768Hz crystal load capacitance matches the recommended 12.5 pF in the datasheet, otherwise the real-time clock domain will drift.
The 256-MAPBGA exposed-die variant of the i.MX1 can dissipate up to 1 W at full 200 MHz CPU load with all peripherals active. Place a thermal via array (0.3 mm drill, 1.2 mm pitch) directly under the die-up region to draw heat into the inner copper planes. For sealed enclosures, derate power by clock-gating unused peripherals; for industrial temperature operation, validate with an infrared thermal probe that the case temperature stays below 70 C at worst-case ambient.
Información de cumplimiento
Compliance status not explicitly stated in verified web sources as of 2026-10-16. The MC9328MX1VH20 is not AEC-Q100 qualified; designers targeting automotive should verify thermal and vibration compliance at the system level.
