MC9328MX1VH20

The MC9328MX1VH20 is an i.MX1 series microprocessor from NXP Semiconductors featuring an ARM920T core running at up to 200 MHz. It targets personal and portable products that require an integrated processor with on-chip peripheral support for multimedia and human interface applications.

Designed for compact embedded systems, the device combines a single 32‑bit ARM920T core with integrated controllers such as an SDRAM controller, LCD controller and USB device to reduce external component count and simplify system design.

Key Features

• Core ARM920T single-core, 32‑bit microprocessor operating at up to 200 MHz for control and multimedia tasks.
• Memory and Bus On-chip SDRAM controller (SDRAMC) and internal bus interfaces (AHB to IP Bus Interfaces) to support system memory and peripheral access.
• Display and Human Interface Integrated LCD controller and touch panel support for direct driving of display-based user interfaces.
• Integrated Peripherals Includes a USB device (USB 1.x), MMC/SD host controller and Memory Stick® host controller for removable storage and connectivity.
• Serial and Audio Interfaces Multiple UARTs, SPI, two synchronous serial interfaces (SSI/I2S) and an I2C bus module for diverse serial communications and audio paths.
• Timers and System Two 32‑bit timers, watchdog timer and real‑time clock (RTC) for reliable timing and system control.
• Data Movement Direct Memory Access Controller (DMAC) to offload bulk data transfers from the CPU.
• Clock and Power Control DPLL clock and power control module to manage system clocks and power domains.
• Analog and Acceleration Analog Signal Processing (ASP) block and Bluetooth accelerator referenced in the device architecture for targeted subsystem support.
• Package and Mounting 256-contact Mold Array PBGA (256‑PBGA, 14×14) surface-mount package for compact board-level integration.
• Operating Temperature Rated for commercial operation from 0 °C to 70 °C.
• Standards and Compliance RoHS compliant.

Typical Applications

• Portable Multimedia Devices Integrated LCD, MMC/SD and USB support enable compact handheld products that deliver audio/video and user interface functionality.
• Handheld and Personal Electronics Single 32‑bit ARM920T core and on‑chip peripherals simplify designs for personal, portable products.
• Embedded Human-Machine Interfaces LCD controller and touch panel support make the device suitable for control panels, displays and interactive embedded interfaces.
• Storage-Enabled Embedded Systems MMC/SD and Memory Stick® host controllers allow local removable storage for data logging, media playback or firmware updates.

Unique Advantages

• Highly integrated peripheral set: On-chip LCD controller, USB device and MMC/SD host reduce external components and simplify board design.
• Focused multimedia capability: ARM920T core combined with display and audio interfaces supports multimedia functionality in compact form factors.
• Robust system control: Built-in timers, watchdog, RTC and DMAC provide deterministic control and efficient data movement for embedded applications.
• Compact package footprint: 256‑contact PBGA (14×14) packaging enables dense PCB layouts for space-constrained products.
• Power and clock management: DPLL clock and power control module aids in managing system clocks and power domains for portable designs.
