NXP Semiconductors MC9328MXLVP20

Overview

MC9328MXLVP20 from NXP Semiconductors (formerly Freescale) is an ARM920T™-based applications processor operating at 200 MHz, featuring integrated SDRAM controller, LCD controller, USB Device, MMC/SD host controller, and multimedia accelerator. It targets portable multimedia devices requiring low-power, high-integration SoC solutions with 225-ball MAPBGA packaging.

For engineers reviewing the MC9328MXLVP20 datasheet, MC9328MXLVP20 pinout, MC9328MXLVP20 application, or MC9328MXLVP20 equivalent, key selection criteria include core frequency (200 MHz), I/O voltage range (1.7–3.3 V), operating temperature (0°C to 70°C), 225-ball MAPBGA package compatibility, and integrated peripheral support for LCD, USB, and SD interfaces.

Technical Context

The MC9328MXLVP20 implements an ARM920T™ core with Harvard architecture, 16 KB instruction and 16 KB data caches, and a Memory Management Unit (MMU). Its system-level integration includes an External Interface Module (EIM) supporting NOR/NAND flash and SRAM, dual UARTs with IrDA/Auto-bauding, and a DMA controller with 11 channels.

Power management is handled by a DPLL clock and power control module enabling dynamic voltage/frequency scaling. The processor supports both big- and little-endian operation via the BIG_ENDIAN pin and provides dedicated video port signals (CSI_D[7:0], CSI_VSYNC, CSI_HSYNC) for CMOS sensor interfacing alongside LCD timing outputs (FLM/VSYNC, LP/HSYNC, LSCLK).

Key Specifications

Pinout & Package

MC9328MXLVP20 is housed in a 225-ball Molded Array Process Ball Grid Array (MAPBGA), Case 1304B-01, with 1.0 mm ball pitch and 13 mm × 13 mm body size. Power and ground balls are distributed across multiple VDD/VSS pairs (NVDD1–NVDD4, QVDD1–QVDD4, AVDD1, NVSS, QVSS) to support independent supply domains for digital I/O, core logic, and analog functions.

FAQ

What is the maximum operating frequency of the MC9328MXLVP20?

The MC9328MXLVP20 operates at a guaranteed maximum core frequency of 200 MHz under specified conditions: QVDD = 1.8–2.0 V, TA = 0°C to 70°C. This frequency is validated across process, voltage, and temperature corners per Freescale's Rev. 8 datasheet. The MC9328MXLVP20 does not support overclocking beyond this rated speed, and sustained operation above 200 MHz may result in timing violations or data corruption.

Does the MC9328MXLVP20 support DDR SDRAM?

No, the MC9328MXLVP20 supports only single-data-rate (SDR) SDRAM, as confirmed by its SDRAM controller documentation, signal naming (SDCLK, RAS, CAS, SDWE), and timing diagrams in the Rev. 8 datasheet. It lacks DDR-specific signals such as DQS, DM, or ODT control. The MC9328MXLVP20 SDRAMC complies with JEDEC Standard No. 22, which defines SDR SDRAM - not DDR or LPDDR. For DDR support, later i.MX generations (e.g., i.MX31) must be considered.

What package type and ball count does the MC9328MXLVP20 use?

The MC9328MXLVP20 uses a 225-contact Mold Array Process Ball Grid Array (MAPBGA), designated Case 1304B-01, with 1.0 mm ball pitch and 13 mm × 13 mm body size. This matches the "VP" suffix in the part number (vs. "VM" for 256-ball variant). Pin assignments and power ball distribution are documented in Table 3 of the MC9328MXL Technical Data Rev. 8, confirming 225 unique solder balls including NVDD, QVDD, AVDD, and NVSS/QVSS domains.

Can the MC9328MXLVP20 operate with a 1.7 V core supply?

No - the MC9328MXLVP20 requires a minimum core supply (QVDD) of 1.8 V when operating at 200 MHz, as specified in Table 5 (Recommended Operating Range) of the Rev. 8 datasheet. At 1.7 V, the device is only rated for ≤150 MHz operation (as in MC9328MXLVP15). Attempting 200 MHz operation at 1.7 V violates electrical specifications and risks setup/hold time failures, cache coherency errors, or unpredictable resets.

Is the MC9328MXLVP20 pin-compatible with the MC9328MXLVM20?

No - the MC9328MXLVP20 (225-ball MAPBGA) and MC9328MXLVM20 (256-ball MAPBGA) have different packages, ball counts, and pinouts. They share identical functionality and register maps, but mechanical and electrical pin mapping differs significantly: e.g., SDCLK appears on R8 in VP20 but on T10 in VM20; LD15 is on F13 in VP20 but on P15 in VM20. PCB layout is not interchangeable, and no adapter or footprint conversion is supported.
