FAQ

What is the maximum operating frequency of the MC9328MXLDVM20R2?

The MC9328MXLDVM20R2 operates at a guaranteed maximum frequency of 200 MHz. This is validated under the recommended operating conditions: QVDD = 1.8–2.0 V and ambient temperature from –30°C to +70°C. The ARM920T™ core achieves this performance with integrated caches and optimized memory controller latency settings. The MC9328MXLDVM20R2 does not support overclocking beyond 200 MHz per Freescale's Rev. 8 datasheet specifications.

Does the MC9328MXLDVM20R2 support USB host functionality?

No, the MC9328MXLDVM20R2 only implements a USB 2.0 full-speed Device controller - not a host controller. It supports USB device classes such as CDC (communication device), MSC (mass storage), and HID (human interface device) when connected to a host PC or hub. For USB host capability, external PHY and controller logic would be required, which is not integrated into the MC9328MXLDVM20R2 silicon.

What package type and ball count does the MC9328MXLDVM20R2 use?

The MC9328MXLDVM20R2 uses a 225-ball Mold Array Process Ball Grid Array (MAPBGA) package, designated Case 1304B-01. It has an 11 × 11 ball array with 0.8 mm pitch and measures 11 mm × 11 mm. This package is distinct from the 256-ball variant (e.g., MC9328MXLVM20R2) and is not pin-compatible with it due to different signal mapping and power pin distribution.

Can the MC9328MXLDVM20R2 boot from NAND flash?

Yes, the MC9328MXLDVM20R2 supports NAND flash boot via its External Interface Module (EIM) when BOOT[3:0] pins are configured appropriately (e.g., BOOT[3:0] = 0b0010). The boot ROM includes NAND flash controller initialization routines and supports common NAND devices with 8-bit or 16-bit data buses, hardware ECC, and standard ONFI timing parameters - as documented in the MC9328MXL Reference Manual.

What is the function of the CSI interface on the MC9328MXLDVM20R2?

The CSI (CMOS Sensor Interface) on the MC9328MXLDVM20R2 provides an 8-bit parallel video input path with dedicated signals: CSI_D[7:0], CSI_PIXCLK, CSI_HSYNC, CSI_VSYNC, and CSI_MCLK. It supports synchronous capture from OV76xx-series and compatible CMOS image sensors at pixel clocks up to 25 MHz, enabling VGA-resolution video at 15–30 fps without external frame buffer or bridge IC. The interface is fully register-configurable for timing polarity and data format.
