NXP Semiconductors MC9328MXLVP15

Overview

MC9328MXLVP15 from Freescale Semiconductor is an ARM920T™-based applications processor operating at 150 MHz, packaged in a 225-ball MAPBGA (Case 1304B-01). It integrates SDRAM controller, LCD controller, USB Device, MMC/SD host, and SPI/UART/I²C peripherals. Designed for portable multimedia devices, it supports 1.7–1.9 V core voltage and 1.7–3.3 V I/O voltage with power management features.

For engineers reviewing the MC9328MXLVP15 datasheet, MC9328MXLVP15 pinout, MC9328MXLVP15 application, or MC9328MXLVP15 equivalent, key selection considerations include its 150 MHz ARM920T™ core speed, 225-ball MAPBGA package, integrated LCD and USB Device interfaces, SDRAM controller timing, and temperature range (0°C to 70°C).

Technical Context

The MC9328MXLVP15 implements an ARM920T™ microprocessor core with Harvard architecture, MMU, and 16 KB instruction + 16 KB data caches. Its external interface module (EIM) supports asynchronous SRAM, NOR flash, and burst-mode synchronous memories via configurable chip-selects and byte strobes.

It features dual clock domains: QVDD-powered core logic (1.7–1.9 V @ 150 MHz) and NVDD-powered I/O (1.7–3.3 V), with dedicated AVDD for analog functions including 32 kHz RTC crystal interface and 4–16 MHz main oscillator input. The SDRAM controller supports 16-bit wide SDRAM with programmable CAS latency and auto-refresh.

Key Specifications

Pinout & Package

MC9328MXLVP15 uses a 225-ball MAPBGA (Case 1304B-01) package with 13 mm × 13 mm body size and 0.8 mm ball pitch. Power and ground balls are distributed across multiple VDD/VSS pairs (NVDD1–NVDD4, QVDD1–QVDD4, AVDD1, NVSS, QVSS) to minimize noise coupling between digital, analog, and core domains.

FAQ

What is the maximum operating frequency of the MC9328MXLVP15?

The MC9328MXLVP15 is factory-specified and tested to operate at a maximum core frequency of 150 MHz. This speed is guaranteed under the recommended operating conditions: QVDD = 1.7–1.9 V and ambient temperature 0°C to 70°C. Exceeding this frequency may result in timing violations or functional failure.

Does the MC9328MXLVP15 support external SDRAM, and what configurations are validated?

Yes, the MC9328MXLVP15 includes a dedicated SDRAM controller supporting 16-bit-wide devices. Validated configurations include single-bank 32 Mbit to 256 Mbit SDRAM parts with programmable CAS latency (2 or 3), burst length (1, 2, 4, 8, or full page), and auto-refresh intervals. The controller drives SDCLK, SDRAS, SDCAS, SDWE, and DQM signals directly.

What package type and ball count does the MC9328MXLVP15 use?

The MC9328MXLVP15 uses a 225-ball Molded Array Process Ball Grid Array (MAPBGA) package, designated Case 1304B-01. It measures 13 mm × 13 mm with 0.8 mm ball pitch and includes separate power domains (QVDD, NVDD1–4, AVDD1, QVSS, NVSS) for noise isolation.

Can the MC9328MXLVP15 boot from SD card or MMC?

No, the MC9328MXLVP15 does not support booting directly from SD or MMC cards. Boot sources are selected via BOOT[3:0] pins and include NOR flash, NAND flash, SPI flash, and internal ROM. SD/MMC interfaces are operational only after boot and initialization by firmware.

What is the function of the TRISTATE pin on the MC9328MXLVP15?

The TRISTATE pin (ball AVDD1, N14) forces all I/O signals into high-impedance state for boundary-scan testing. During normal operation, it must be terminated with a 1 kΩ resistor to ground. Leaving it floating or asserting it high will disable all I/O functionality and halt system operation.
