MC9328MX1DVM20 概述
A microprocessor is an integrated circuit that contains the arithmetic logic unit, control unit, registers, and cache memory of a computer on a single silicon die, executing instructions fetched from external memory. Within the broader taxonomy, the MC9328MX1 sits in the microprocessor (MPU) category, which is distinct from microcontrollers (MCU) in that MPUs typically require external memory and are used in applications needing higher computational throughput and richer operating-system support (Linux, Windows CE). The i.MX1 family was NXP's first ARM9-based application processor line, targeting PDAs, smart phones, and portable media players of the early 2000s.
Key features of the MC9328MX1DVM20 include the ARM920T core with MMU and Harvard cache architecture, integrated LCD controller supporting STN and TFT panels, USB 1.1 full-speed host and device ports, multimedia card (MMC) and Secure Digital (SD) interfaces, and a wide operating voltage range suitable for battery-powered designs. The MAPBGA-225/256 plastic package enables compact board layout for handheld form factors.
Architecturally, the i.MX1 leverages the ARM920T's five-stage pipeline with separate 16 KB instruction and 16 KB data caches, plus a write buffer. An AMBA bus matrix connects the core to on-chip peripherals including the system controller, DMA, and external memory interface supporting SDRAM, NOR flash, and NAND flash, making the part suitable for running embedded operating systems.
Typical applications for the MC9328MX1DVM20 include handheld data terminals, industrial HMI panels, portable medical devices, point-of-sale terminals, and legacy embedded Linux systems. Designers choose this part when they need proven ARM9 software support and a mature peripheral set, particularly in long-life-cycle industrial products where newer Cortex-A cores are not required.
When designing with this part, pay close attention to power sequencing (core and I/O rails must be sequenced per the datasheet) and ensure the PCB footprint matches the 256-ball MAPBGA land pattern. Refer to the Freescale/NXP i.MX1 reference manual for memory interface timing and bootloader configuration.

典型应用
MC9328MX1DVM20 适用于 8 应用s: Handheld Data Terminal, Industrial HMI Panel, Portable Medical Monitor, Point-of-Sale (POS) Terminal, Embedded Linux Gateway, Portable Media Player (Legacy), Automotive Infotainment (Legacy), Smart Home Controller.
Handheld Data Terminal
The MC9328MX1DVM20 fits handheld data terminals because its 200 MHz ARM920T core and integrated LCD controller deliver responsive UI performance, while the USB 1.1 and UART peripherals support barcode scanners and WLAN modules. The 1.7V-3.3V supply range is well-suited to battery-powered designs with a single Li-ion cell plus an LDO. Compared to newer Cortex parts, the i.MX1's mature Linux 2.6 BSP enables rapid porting of barcode- and inventory-management applications.
推荐
Industrial HMI Panel
For industrial human-machine interface panels, the MC9328MX1DVM20 provides the LCD controller needed for TFT panels up to SVGA, the GPIO count required for keypad and indicator interfacing, and the MMU that supports real-time operating systems such as Embedded Linux or WinCE. Designers should use the CVM20 industrial temperature grade variant if operating above 70 C, and add watchdog and brown-out supervisor ICs to meet IEC 61131-2 expectations.
推荐
Portable Medical Monitor
The MC9328MX1DVM20 suits portable patient monitors and medical data loggers where deterministic ARM9 performance, USB device connectivity for charging/data transfer, and a compact MAPBGA-256 footprint are required. The integrated peripherals (SPI, I2C, UART) interface cleanly to AFE chips for SpO2, ECG, or temperature sensing. For new medical designs, verify ISO 13485 process compliance and select the i.MX1 variant matching your risk classification.
推荐
Point-of-Sale (POS) Terminal
POS terminals leverage the MC9328MX1DVM20's USB host port for keyboard and printer peripherals, the LCD controller for customer-facing displays, and the MMC/SD interface for transaction logging. The ARM920T's MMU supports full Linux, allowing use of mainstream payment-applicaton stacks and TLS libraries. Use AES hardware accelerators if your stack requires PCI-P2PE crypto offload.
推荐
Embedded Linux Gateway
Industrial gateways and protocol converters use the MC9328MX1DVM20 to run embedded Linux with full networking stacks (TCP/IP, Modbus, CAN, MQTT). The part's external SDRAM and NOR/NAND flash interface supports typical gateway memory configurations (32 MB RAM, 8 MB flash). The 200 MHz core is adequate for routing, protocol translation, and lightweight TLS workloads typical of edge gateways.
推荐
Portable Media Player (Legacy)
The i.MX1 family was originally designed for portable media players, and the MC9328MX1DVM20 drives STN/TFT panels, manages audio via I2S, and decodes MP3/AAC in software at 200 MHz. While not a modern design choice for new PMPs, it remains a viable processor for audio docks, digital photo frames, and other consumer multimedia appliances where cost-effective ARM9 performance is sufficient.
推荐
Automotive Infotainment (Legacy)
Although superseded by i.MX6 and i.MX8 in modern automotive designs, the MC9328MX1DVM20 was deployed in early 2000s telematics and infotainment head units. Designs targeting automotive use must select the AEC-Q100-qualified variants from the i.MX family rather than the commercial-grade MC9328MX1DVM20. This is provided for historical context only.
推荐
Smart Home Controller
Smart-home concentrators and edge controllers can leverage the MC9328MX1DVM20's mature Linux support, USB host for Zigbee/Z-Wave dongles, and GPIO/SPI for local sensor networks. Although newer parts offer lower power and higher integration, the i.MX1 remains in long-life products such as security panels and HVAC controllers where field-proven reliability outweighs the need for bleeding-edge performance.

关键差异点

- Integrated USB host and device （对比 External USB controller plus lower-end MCU)
设计说明
Estimated: at 200 MHz core clock and 1.8 V core rail, the i.MX1 core current is roughly 150-200 mA active, plus I/O current. Sequence the 1.8 V core rail after (or simultaneously with) the 3.3 V I/O rail to avoid latch-up. Use an LDO such as the MC33269 for the core rail and ensure the POR (power-on-reset) timing per the datasheet is met before reset is deasserted.
The 256-ball MAPBGA package has a relatively high junction-to-ambient thermal resistance (theta_JA in the 30-50 C/W range for typical 4-layer boards). At typical i.MX1 active power dissipation of 0.5-1 W, junction rise over ambient is 15-50 C - manageable but verify with a thermal prototype before locking the mechanical design.
MAPBGA-256 requires controlled-impedance PCB routing for the SDRAM bus and signal integrity for high-speed clocks. Use 50 ohm single-ended impedance on trace-matched SDRAM nets and place decoupling capacitors as close to each BGA quadrant as the layout allows. Refer to the i.MX1 hardware reference design for via-in-pad and microvia recommendations.
Do not mix the i.MX1 (ARM920T) bootloader/BSP with i.MX21 (ARM926) or i.MX31 (ARM1136) binaries - the cores are software-incompatible at the assembly level. Verify the part marking against the order code before flashing firmware. Also note that the boot mode configuration pins are sampled at reset and must be pulled high or low through 10 kohm resistors per the desired boot source.
Route the SDRAM clock, clock-enable, and chip-select signals with matched lengths (typically within 0.5 mm of the longest signal in the byte group) and isolate the analog audio PLL supply from digital switching noise. The exposed-pad thermal pad must be soldered to the PCB ground plane to meet the package's thermal and electrical performance.
合规信息
