MC9328MX1DVH20

The MC9328MX1DVH20 is an NXP Semiconductors i.MX1 series embedded microprocessor built around an ARM920T core running at up to 200 MHz. It integrates processor performance with a set of system peripherals and memory interfaces tailored for personal and portable embedded applications that require compact, power-efficient multimedia-capable processing.

With on-chip peripherals including USB device support, an LCD controller and MMC/SD host capability, the device targets portable multimedia and human-interface designs where integration and system-level functionality reduce BOM and simplify board design.

Key Features

• Core  ARM920T single-core, 32-bit processor operating at up to 200 MHz as specified for the i.MX1 family.
• Memory and Bus  Integrated SDRAM controller (SDRAMC) and embedded SRAM to support system memory needs and external memory interfacing.
• Display and Human Interface  LCD controller and touch-panel display interface for user-facing applications and graphical interfaces.
• Multimedia and I/O  Multimedia interfaces including MMC/SD host controller, Memory Stick host controller, SSI/I2S audio interfaces, and a Bluetooth accelerator module referenced in the series documentation.
• Serial and Peripheral Interfaces  Multiple UARTs (three), two SPI ports, I²C bus module, USB device, and general-purpose I/O (GPIO) for broad peripheral connectivity.
• System and Timing  On-chip DMA controller (DMAC), two 32-bit timers/counters, PWM module, watchdog timer and real-time clock for control and real-time tasks.
• Power and Clock Control  DPLL clock and power control module as described in the series technical data for system power and clock management.
• Package and Mounting  256-contact PBGA package (14 × 14 mm, supplier device package: 256-PBGA / package case: 256-LFBGA) designed for surface-mount assembly.
• Operating Range and Compliance  Specified operating temperature range of −30 °C to 70 °C and RoHS-compliant status.
• Graphics  No dedicated graphics acceleration, per the provided specifications.

Typical Applications

• Handheld Multimedia Devices  Integrated MMC/SD host, audio interfaces and LCD controller make the device suitable for compact portable media players and handheld appliances.
• Portable Consumer Electronics  USB device support, SDRAM controller and general-purpose I/O enable compact personal devices that require mass-storage and peripheral connectivity.
• Human-Machine Interfaces  LCD and touch-panel interface support simplifies development of user interfaces for handheld terminals and control panels.
• Embedded Control with Real-Time Needs  On-chip DMA, timers, watchdog and RTC support embedded control tasks and timekeeping in battery-powered products.

Unique Advantages

• Integrated peripheral set: On-chip USB device, MMC/SD host, LCD controller and multiple serial interfaces reduce external component count and simplify system design.
• Balanced compute and system I/O: ARM920T at 200 MHz combined with DMA and multiple serial/I²C/SPI interfaces delivers a practical balance of processing and peripheral bandwidth for embedded multimedia tasks.
• Compact surface-mount package: 256-contact PBGA (14×14 mm) provides high pin density for complex I/O while remaining suitable for compact PCB layouts.
• Extended commercial temperature rating: −30 °C to 70 °C supports a wide range of portable and industrial ambient conditions.
• Documented platform: Part of the i.MX1 family with detailed technical data and functional descriptions to support development and integration.
• RoHS compliant: Aligns with lead-free manufacturing requirements for modern electronics production.
