FAQ

What is the maximum operating frequency of the MC9328MX1VM20R2?

The MC9328MX1VM20R2 operates at a guaranteed maximum frequency of 200 MHz across its specified temperature range (0°C to 70°C). This speed is achieved using the ARM920T™ core with on-chip PLL clock generation and is validated under worst-case voltage (1.7 V core) and temperature conditions per Freescale's MC9328MX1 Technical Data Rev. 7.

Does the MC9328MX1VM20R2 support USB host functionality?

No, the MC9328MX1VM20R2 only implements a USB 1.1 Device controller. It cannot act as a USB host to connect peripherals like keyboards or flash drives. The USB interface supports device-class roles including CDC, HID, and mass storage, but requires an external host (e.g., PC) to initiate communication. MC9328MX1VM20R2 does not contain OTG or host PHY circuitry.

What LCD interface capabilities does the MC9328MX1VM20R2 provide?

The MC9328MX1VM20R2 includes a fully integrated LCD controller supporting 16-bit RGB/TFT panels up to XGA resolution (1024×768), with programmable pixel clock, HSYNC/VSYNC polarity, and Sharp-panel-specific signals (e.g., SPL_SPR, PS, CLS). It drives displays directly without external timing generators and supports both passive and active matrix types via configurable output formats.

Is the MC9328MX1VM20R2 pin-compatible with other i.MX1 variants like MC9328MX1VM15R2?

Yes, all MC9328MX1 variants-including MC9328MX1VM15R2 (150 MHz) and MC9328MX1VM20R2 (200 MHz)-share identical 225-ball MAPBGA packaging and pinout. Differences are limited to speed grade and temperature rating; no PCB redesign is required when upgrading within the same package option, provided power delivery and thermal design accommodate the higher-frequency variant.

What power supply configurations are required for the MC9328MX1VM20R2?

The MC9328MX1VM20R2 requires three independent supply domains: QVDD (1.7–1.9 V core), NVDD (1.7–3.3 V I/O), and AVDD (2.5–3.3 V analog). Each domain must be decoupled with low-ESR capacitors per Freescale's layout guidelines. AVDD powers the ASP, RTC, and PLL circuits; improper sequencing or noise on QVDD can cause core instability or cache errors in MC9328MX1VM20R2 operation.
