For engineers reviewing the MC9328MX1DVM15R2 datasheet, MC9328MX1DVM15R2 pinout, MC9328MX1DVM15R2 application, or MC9328MX1DVM15R2 equivalent, key selection considerations include its 225-ball MAPBGA package, -30°C to 70°C industrial temperature grade, integrated multimedia accelerators (MMA/BTA), and boot-mode configuration via BOOT[3:0] pins.

Technical Context

The MC9328MX1DVM15R2 implements the ARM920T core with Harvard architecture, 16 KB instruction and 16 KB data caches, and a Memory Management Unit (MMU). Its system-on-chip integration includes dedicated modules for LCD timing control (LD[15:0], FLM/VSYNC), USB 1.1 device PHY (USBD_VP/VM), and SDRAM interface (SDBA[4:0], MA[11:0], DQM[3:0]).

It features three configurable UARTs (UART1–UART3), two SPI interfaces (SPI1/SPI2), dual I²C buses, and a 32-bit external bus interface supporting up to 256 MB address space. Power management includes dynamic clock gating, multiple sleep modes, and voltage scaling support across its 1.7–1.9 V core supply range.

FAQ

What is the maximum operating frequency of the MC9328MX1DVM15R2?

The MC9328MX1DVM15R2 is rated for a maximum operating frequency of 150 MHz. This speed is guaranteed across its specified industrial temperature range (-30°C to +70°C) and core supply voltage range (1.7 V to 1.9 V). The part does not support dynamic frequency scaling above this rating, and operation beyond 150 MHz may result in timing violations or data corruption. The MC9328MX1DVM15R2 achieves this frequency using a phase-locked loop (PLL) that multiplies the 16 MHz crystal input (EXTAL16M) by a factor of 9.375.

Does the MC9328MX1DVM15R2 support USB host functionality?

No, the MC9328MX1DVM15R2 only implements a USB 1.1 device controller-not a host or OTG controller. Its USB interface (USBD_VP, USBD_VM, USBD_SUSPND, etc.) is strictly configured for peripheral operation, enabling the MC9328MX1DVM15R2 to act as a mass storage device or CDC-class modem when connected to a PC or host system. To add USB host capability, an external USB host controller IC (e.g., ISP1362) must be used, connected via the MC9328MX1DVM15R2's external bus interface.

How is boot source selected on the MC9328MX1DVM15R2?

Boot source selection on the MC9328MX1DVM15R2 is controlled by the four BOOT[3:0] pins (BGA pins P12, N12, R13, P11), sampled at power-on reset. These pins configure one of eight boot modes-including NOR flash (CS0), NAND flash (CS3), or serial ROM-per Table 4-1 in the reference manual. External pull-up or pull-down resistors (typically 10–100 kΩ) must be applied to each BOOT pin to set the desired logic state; floating inputs will cause undefined boot behavior. The MC9328MX1DVM15R2 does not support runtime boot mode reconfiguration.

What LCD panel types are supported by the MC9328MX1DVM15R2's built-in controller?

The MC9328MX1DVM15R2's LCD controller supports 16-bit parallel RGB TFT panels up to VGA resolution (640×480), including Sharp HR-TFT panels via dedicated control signals (SPL_SPR, PS, CLS, REV). It also supports passive STN and CSTN displays using appropriate timing parameters. The controller outputs LD[15:0], FLM/VSYNC, LP/HSYNC, LSCLK, and ACD/OE, and supports programmable polarity, pixel clock division, and frame buffering. No external timing generator is required for standard configurations, though custom waveforms may need GPIO-assisted control.

Is the MC9328MX1DVM15R2 pin-compatible with other i.MX1 variants like MC9328MX1VM20R2?

Yes, all i.MX1 family members-including MC9328MX1DVM15R2, MC9328MX1VM20R2, and MC9328MX1CVM15R2-share identical 225-ball MAPBGA pinouts and signal assignments per Case 1304B-01. Differences are limited to operating frequency (150 MHz vs. 200 MHz), temperature grade (-30°C to +70°C vs. 0°C to +70°C or -40°C to +85°C), and solderball composition (Pb-free). This allows direct PCB reuse across variants, provided power delivery and thermal design accommodate the specific speed/temperature grade.
