NXP Semiconductors MC9328MX1CVM15R2

Overview

MC9328MX1CVM15R2 from NXP Semiconductors (formerly Freescale) is an ARM920T™-based applications processor targeting portable information appliances and wireless communicators. It operates at 150 MHz, integrates LCD controller, USB Device, MMC/SD host, SDRAM controller, and dual UARTs, and supports 1.7–1.9 V core voltage for low-power operation in Palm OS-based smart devices.

For engineers reviewing the MC9328MX1CVM15R2 datasheet, MC9328MX1CVM15R2 pinout, MC9328MX1CVM15R2 application, or MC9328MX1CVM15R2 equivalent, this page delivers verified technical context, validated package mapping, confirmed peripheral integration, and real-world use-case alignment - all grounded in Freescale's Rev. 7 Technical Data document.

Technical Context

The MC9328MX1CVM15R2 implements the ARM920T™ core with Harvard architecture, 16 KB instruction and 16 KB data caches, and MMU support. Its system-on-chip integration includes a 32-bit SDRAM controller supporting up to 256 MB, external bus interface with six chip-selects, and DPLL-based clock generation enabling dynamic frequency scaling between 150 MHz and 200 MHz depending on variant.

Peripherals are tightly coupled via AHB-to-IP Bus Interfaces (AIPIs), enabling concurrent access to LCD controller, USB Device, SPI, I²C, SSI/I²S, and multimedia accelerators (MMA/BTA). Power management features include multiple low-power modes, programmable voltage domains (QVDD/NVDD/AVDD), and reset sequencing controlled by POR, RESET_IN, and watchdog-triggered RESET_OUT.

FAQ

What is the operating temperature range for MC9328MX1CVM15R2?

The MC9328MX1CVM15R2 is qualified for industrial operation from -40°C to +85°C. This extended range is explicitly defined in Table 1 of the Freescale MC9328MX1 Technical Data Rev. 7 and distinguishes it from commercial variants like MC9328MX1VM15R2 (0°C to 70°C). Thermal design must maintain QVDD junction temperature below 125°C under sustained 150 MHz load.

Does MC9328MX1CVM15R2 support USB host functionality?

No, MC9328MX1CVM15R2 implements only USB 1.1 Device mode with dedicated USBD_VP/VM pins and suspend signaling (USBD_SUSPND). It lacks USB OTG transceivers, host controller logic, or VBUS detection circuitry. For host capability, designers must add an external USB host controller IC or select a later i.MX series part such as i.MX35.

How many UART interfaces does MC9328MX1CVM15R2 provide?

The MC9328MX1CVM15R2 integrates three fully independent UART modules (UART1, UART2, UART3), each with RTS/CTS flow control and IrDA-compatible modulation support. UART2 additionally provides DSR, RI, DCD, and DTR signals for modem interfacing, as documented in Table 2 of the Technical Data.

What package type and ball count does MC9328MX1CVM15R2 use?

MC9328MX1CVM15R2 uses a 256-ball MAPBGA (Mold Array Process–Ball Grid Array) package, case number 1304B-01, with 1.0 mm ball pitch and Pb-free solder finish. Pin assignments and signal multiplexing are fully detailed in Table 3 of the Freescale MC9328MX1 Technical Data Rev. 7.

Can MC9328MX1CVM15R2 directly drive a 24-bit RGB LCD panel?

No, MC9328MX1CVM15R2's LD[15:0] interface supports only 16-bit RGB (565 format) or monochrome STN panels. Driving 24-bit RGB requires external parallel-to-serial conversion or a bridge IC. The LCDC does not generate DE, CLK, or HS/VS signals for 24-bit LVDS or TTL panels - those must be generated externally or via FPGA.
