Product details
Overview
MC9328MX1VH20 from NXP Semiconductors (formerly Freescale) is an ARM920T™-based applications processor targeting portable multimedia devices. It operates at 200 MHz, integrates LCD controller, USB Device, MMC/SD host, SDRAM controller, and dual UARTs, and supports 1.7–1.9 V core voltage. It was used in Palm OS-based smart communicators like the Accompli 008.
For engineers reviewing the MC9328MX1VH20 datasheet, MC9328MX1VH20 pinout, MC9328MX1VH20 application, or MC9328MX1VH20 equivalent, key selection factors include its 256-pin MAPBGA-225 package, integrated multimedia accelerators (MMA/BTA), real-time clock, and support for boot from NAND/NOR flash via configurable BOOT[3:0] pins.
Technical Context
The MC9328MX1VH20 implements a 32-bit ARM920T core with Harvard architecture, 16 KB instruction and 16 KB data caches, and MMU. Its memory subsystem includes a 32-bit SDRAM controller supporting up to 256 MB, external interface module (EIM) for NOR/NAND/ROM, and dynamic power management via DPLL clock control.
Peripherals are organized into dedicated AHB/APB bridges: LCD controller drives STN/TFT panels with programmable timing; USB Device complies with USB 2.0 full-speed (12 Mbps); MMC/SD host supports SD v1.1 and MMC v3.31; and dual SSI modules operate in I²S or AC97 mode for audio codecs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| i.MX21 (MC9328MX21) | ARM926EJ-S core, 266 MHz, added security engine and enhanced USB OTG support | Better suited for secure data transfer and host-mode USB peripherals | Select when cryptographic acceleration or USB host capability is required beyond MC9328MX1VH20's USB device-only functionality |
| OMAP-730 | TMS320C55x DSP + ARM925T dual-core, 200 MHz, integrated power management unit | Stronger DSP performance for voice coding and audio preprocessing | Prefer for voice-centric applications requiring G.729 or AMR-WB codec offload not supported by MMA/BTA blocks |
Compared with i.MX21 and OMAP-730, MC9328MX1VH20 offers lower power consumption in display-intensive handhelds due to its optimized LCD controller and absence of high-overhead security/DSP subsystems, making it ideal for cost-sensitive Palm OS derivatives where USB device and SD host are primary connectivity needs.

FAQ
What is the maximum SDRAM capacity supported by the MC9328MX1VH20?
The MC9328MX1VH20 supports up to 256 MB of SDRAM via its 32-bit SDRAM controller with programmable row/column addressing and bank control. This capacity is achieved using two 128 MB chips in 16-bit configuration or a single 256 MB chip in 32-bit mode, with timing parameters configured through SDRAMC registers per JEDEC standards.
Does the MC9328MX1VH20 support USB host functionality?
No, the MC9328MX1VH20 only implements a USB 2.0 full-speed device controller-not a host or OTG controller. It supports enumeration as a CDC, HID, or mass storage device but cannot connect to USB peripherals like keyboards or flash drives. For host capability, consider the i.MX21 or later i.MX processors.
How is boot source selected on the MC9328MX1VH20?
Boot source selection on the MC9328MX1VH20 is controlled by the state of BOOT[3:0] pins at reset. These four inputs determine whether the processor boots from NOR flash, NAND flash, OneNAND, or USB download mode. Configuration requires external pull-up/pull-down resistors per Table 1 in the datasheet, with default behavior dependent on pin strapping.
What LCD panel types are compatible with the MC9328MX1VH20's LCDC?
The MC9328MX1VH20's LCD controller supports both passive-matrix STN and active-matrix TFT panels, including Sharp HR-TFT panels via dedicated signals (PS, CLS, REV, SPL_SPR). It provides programmable polarity, HSYNC/VSYNC timing, and pixel clock division to match diverse panel requirements without external timing logic.
Is the MC9328MX1VH20 still in production or available for new designs?
The MC9328MX1VH20 is obsolete and no longer in production by NXP. However, Aetrix Electronics maintains legacy inventory and offers long-term supply support-including traceable, tested units and lifecycle coordination-for existing industrial and medical programs still reliant on this processor.
