NXP Semiconductors MC9328MXLVM20R2

Overview

MC9328MXLVM20R2 from Freescale Semiconductor 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 supports 1.8 V core voltage and 3.3 V I/O, and targets portable multimedia devices requiring rich UI, low-power operation, and peripheral integration.

For engineers reviewing the MC9328MXLVM20R2 datasheet, MC9328MXLVM20R2 pinout, MC9328MXLVM20R2 application, or MC9328MXLVM20R2 equivalent, key selection criteria include 225-ball MAPBGA package compatibility, 200 MHz ARM920T performance with integrated video port and SSI/I²S audio interface, and support for boot from NAND/NOR flash via configurable BOOT[3:0] pins.

Technical Context

The MC9328MXLVM20R2 implements a 32-bit ARM920T core with Harvard architecture, MMU, and 16 KB instruction + 16 KB data caches. Its system-level integration includes AHB-to-IP bus bridges (AIPI), external interface module (EIM) for NOR/NAND/ROM/Flash, and dual UARTs with IrDA/auto-bauding support.

Power management is handled by a DPLL clock and power control module enabling dynamic voltage/frequency scaling. The processor supports multiple boot modes (NOR, NAND, SPI, SD), and its 225-contact MAPBGA package (Case 1304B-01) routes 176 I/O signals across four NVDD-supplied banks, with dedicated AVDD and QVDD domains for analog and core logic.

Key Specifications

Pinout & Package

MC9328MXLVM20R2 is housed in a 225-ball Molded Array Process Ball Grid Array (MAPBGA) package, Case 1304B-01, with 0.8 mm ball pitch and 13 mm × 13 mm body size. Power domains are segregated: QVDD/QVSS for core logic, NVDD/NVSS per I/O bank, and AVDD/AVSS for analog functions (USB, CSI, crystal oscillators).

FAQ

What is the maximum SDRAM capacity supported by the MC9328MXLVM20R2?

The MC9328MXLVM20R2 SDRAM controller supports up to 256 MB of single-channel SDRAM using 16 Mbit × 16-bit devices. Addressing uses MA[11:0], SDBA[4:0], and DQM[3:0] with programmable burst length and CAS latency. The MC9328MXLVM20R2 datasheet specifies timing compliance for -75 and -8K speed grades under 133 MHz operation.

Does the MC9328MXLVM20R2 support boot from NAND flash?

Yes, the MC9328MXLVM20R2 supports NAND flash boot via its External Interface Module (EIM) with hardware ECC generation. Boot mode is selected by pulling BOOT[3:0] = 0b0101; the internal ROM loader initializes the NAND controller, reads first 4 KB into internal SRAM, and executes the bootstrap code. The MC9328MXLVM20R2 requires external 8-bit NAND with spare area for ECC metadata.

What are the power supply sequencing requirements for the MC9328MXLVM20R2?

The MC9328MXLVM20R2 requires strict power-up order: QVDD must stabilize before NVDD and AVDD, with all supplies within ±5 % of nominal before releasing RESET_IN. Power-down follows reverse sequence. Application note AN2537 specifies that QVDD ramp time must exceed 100 µs, and NVDD/AVDD must remain active ≥100 ms after QVDD dropout. The MC9328MXLVM20R2 does not include internal power sequencer.

Can the MC9328MXLVM20R2 drive a 480×272 RGB TFT display directly?

Yes, the MC9328MXLVM20R2 LCD controller supports 480×272 resolution in RGB mode using LD[15:0], FLM/VSYNC, LP/HSYNC, and LSCLK. It configures programmable pixel clock, H/V back/front porch, and sync polarity. The MC9328MXLVM20R2 requires external DC-DC converter to generate VCOM and gamma voltages; Sharp HR-TFT panels are supported via PS/CLS/SPL_SPR signals.

Is the USB interface on the MC9328MXLVM20R2 a full-speed device-only port?

Yes, the MC9328MXLVM20R2 integrates a USB 1.1 full-speed (12 Mbps) device-only transceiver with on-die termination and analog front-end. It lacks USB host capability or OTG support. The MC9328MXLVM20R2 USB module supports CDC, HID, and mass storage classes under Linux and WinCE; external 1.5 kΩ pull-up on USBD_VP is required for device enumeration.
