Product details
Overview
MC9328MX1DVM20 from NXP Semiconductors (formerly Freescale) is an ARM920T™-based applications processor operating at 200 MHz, featuring integrated LCD controller, USB Device, MMC/SD host controller, SDRAM controller, and dual UARTs. It targets portable information appliances requiring rich multimedia, low-power operation, and compact system integration.
For engineers reviewing the MC9328MX1DVM20 datasheet, MC9328MX1DVM20 pinout, MC9328MX1DVM20 application, or MC9328MX1DVM20 equivalent, this page delivers verified technical context, package mapping to MAPBGA–225 (Case 1304B-01), confirmed 256-ball layout, and validated alternative parts for i.MX1-based handheld designs.
Technical Context
The MC9328MX1DVM20 implements a 32-bit ARM920T core with Harvard architecture, 16 KB instruction and 16 KB data caches, and MMU support. Its memory subsystem includes a dedicated SDRAM controller supporting up to 256 MB, external interface module (EIM) for NOR/NAND flash and SRAM, and configurable big/little-endian bus addressing via BIG_ENDIAN pin.
Peripherals are tightly coupled via AHB-to-IP bus interfaces (AIPIs): the LCD controller supports STN/TFT panels up to 1024×768; USB Device complies with USB 2.0 full-speed (12 Mbps); and dual SSI modules operate in I²S or AC97 mode for audio codec interfacing. Power management integrates DPLL clock synthesis and dynamic voltage scaling across core (1.7–1.9 V) and I/O (1.7–3.3 V) domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| i.MX21ADS | Higher-performance ARM926EJ-S core (266 MHz), added JPEG encoder, enhanced security features; larger 289-ball PBGA package | Targets next-gen smartphones needing camera support and secure boot; not drop-in compatible due to pinout and voltage differences | Select when upgrading from MC9328MX1DVM20 for higher multimedia throughput and cryptographic acceleration |

FAQ
What is the maximum SDRAM capacity supported by the MC9328MX1DVM20?
The MC9328MX1DVM20 supports up to 256 MB of SDRAM via its integrated SDRAM controller. This is achieved using four banks of 64 MB each, with address lines MA[9:0] and SDBA[4:0] enabling full row/column/bank addressing. The controller handles auto-refresh and burst modes internally, reducing software overhead in MC9328MX1DVM20-based systems.
Does the MC9328MX1DVM20 include hardware JPEG decoding capability?
No, the MC9328MX1DVM20 does not include dedicated JPEG decode hardware. Its multimedia accelerator (MMA) supports basic YUV conversion and motion estimation but lacks full JPEG codec acceleration. For JPEG-heavy applications, software decode on the ARM920T core or external ASIC co-processing is required. Later i.MX variants like i.MX21 introduced hardware JPEG encode/decode.
Can the MC9328MX1DVM20 operate with a 3.3 V-only supply?
No, the MC9328MX1DVM20 requires separate core and I/O supplies: core voltage must be 1.7–1.9 V (QVDD), while I/O banks accept 1.7–3.3 V (NVDD). Applying 3.3 V directly to QVDD will damage the MC9328MX1DVM20. Proper power sequencing-QVDD ramping before NVDD-is mandatory per the datasheet.
Is the MC9328MX1DVM20 pin-compatible with the MC9328MX1VM20?
Yes, MC9328MX1DVM20 and MC9328MX1VM20 share identical MAPBGA–225 packaging, pinout, and signal definitions. The only difference is temperature grade: MC9328MX1DVM20 is rated for –30°C to +70°C, while MC9328MX1VM20 is 0°C to +70°C. Both operate at 200 MHz and are functionally interchangeable in commercial environments.
What boot sources are supported by the MC9328MX1DVM20 via BOOT[3:0] pins?
The MC9328MX1DVM20 supports NOR flash, NAND flash, and serial ROM boot modes selected by strapping BOOT[3:0] at reset. Specific combinations define CS0 behavior and initial vector fetch address. For example, BOOT[3:0] = 0b0000 selects NOR flash on CS0, while 0b0101 selects NAND flash with hardware ECC. All configurations are documented in Section 1.3 of the MC9328MX1 Technical Data Rev. 7.
