NXP Semiconductors MC9328MXSVP10

Overview

MC9328MXSVP10 from Freescale Semiconductor is an ARM920T™-based applications processor operating at 100 MHz, packaged in a 225-ball MAPBGA (Case 1304B-01). It integrates SDRAM controller, LCD controller, USB Device, dual UARTs, SPI, I²C, PWM, and DMA for portable embedded systems. It targets low-power medical instrumentation, point-of-sale terminals, and security systems requiring open OS support.

For engineers reviewing the MC9328MXSVP10 datasheet, MC9328MXSVP10 pinout, MC9328MXSVP10 application, or MC9328MXSVP10 equivalent, key selection factors include its 1.7–1.9 V core voltage, 225-ball MAPBGA package with signal multiplexing, integrated LCD/USB/SDRAM interfaces, and -40°C to 85°C industrial temperature grade (MC9328MXSCVP10 variant), while MC9328MXSVP10 is rated 0°C to 70°C.

Technical Context

The MC9328MXSVP10 implements the ARM920T core with Harvard architecture, MMU, and 16 KB instruction + 16 KB data cache. Its DPLL clock module generates system clocks from 4–16 MHz crystal inputs, supporting dynamic power management via multiple sleep modes and voltage scaling across QVDD (core) and NVDD/AVDD (I/O/analog) domains.

Signal multiplexing is managed through GPIO control registers, enabling shared pins for functions like ETM trace, LCD data, USB I/O, and external bus signals (A[24:0], D[31:0], CS[5:0]). The External Interface Module (EIM) supports asynchronous and burst-mode memory access, while the SDRAM controller handles 100 MHz operation with MA[11:0], DQM[3:0], RAS/CAS, and SDCKE timing.

Key Specifications

Pinout & Package

MC9328MXSVP10 uses a 225-ball MAPBGA (Case 1304B-01) with 1.0 mm ball pitch and 13 mm × 13 mm body size. Power domains are segregated: QVDD/QVSS for core logic, NVDD/NVSS for I/O banks (NVDD1–NVDD4), AVDD/AVSS for analog blocks (XTAL32K, EXTAL32K, POR), and dedicated TRST/TRISTATE test pins.

Equivalent & Alternatives

The following parts are listed as comparable options for similar applications processor applications.

Compared with i.MX21 and AT91SAM9260, MC9328MXSVP10 offers lower power (120 mA active @ 1.8 V), integrated LCD/USB, and smaller footprint-making it optimal for cost-sensitive, display-centric portable devices where 100 MHz CPU performance suffices.

Availability

MC9328MXSVP10 is available at Aetrix Electronics and suitable for medical instrumentation, point-of-sale terminals, security systems, and industrial HMI panels requiring stable component supply across extended product lifecycles.

Supply support for MC9328MXSVP10 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) designed high-performance, low-power embedded processors for consumer, industrial, and automotive markets before its 2015 acquisition.

The i.MX family-including MC9328MXSVP10-was engineered specifically for portable, battery-powered applications demanding ARM compatibility, integrated peripherals, and power efficiency without sacrificing real-time responsiveness.

FAQ

What is the maximum SDRAM capacity supported by the MC9328MXSVP10?

The MC9328MXSVP10 SDRAM controller supports up to 256 MB using four 64-Mbit banks (x16 data width). Address lines MA[11:0] and bank select signals CSD0/CSD1 enable configuration of up to two independent SDRAM devices. Timing parameters align with PC100/PC133 standards at 100 MHz core frequency, and the controller handles refresh automatically via internal counter.

Does the MC9328MXSVP10 support USB host functionality?

No, the MC9328MXSVP10 only implements a USB 1.1 Device controller. It lacks USB host PHY and OTG capability. All USB signaling (USBD_VP/VM, USBD_SUSPND, USBD_RCV) is strictly device-side; host functionality requires external USB host controller IC or bridge chip connected via UART, SPI, or parallel interface.

How is the boot mode configured on the MC9328MXSVP10?

The MC9328MXSVP10 boot mode is selected by sampling BOOT[3:0] pins at reset. These four inputs determine whether the processor boots from internal ROM, external NOR flash (CS0), NAND flash, or serial EEPROM. Configuration is latched on RESET_IN assertion and cannot be changed dynamically; pull-up/pull-down resistors must be placed externally per Table 1 in the datasheet.

What are the power-up sequencing requirements for MC9328MXSVP10?

MC9328MXSVP10 requires strict power sequencing: NVDD must reach ≥1.8 V before QVDD ramps up, to prevent forward biasing of I/O protection diodes. AVDD may ramp concurrently with NVDD. This is enforced by external supervisor ICs or RC-delay circuits per Application Note AN2537. Failure to observe this sequence risks latch-up or permanent damage.

Can the MC9328MXSVP10's LCD controller drive RGB888 panels?

No, the MC9328MXSVP10 LCD controller outputs only 16-bit RGB565 (LD[15:0]) with fixed pixel clock and sync timing. It does not support 24-bit RGB888 or LVDS output. Panel compatibility is limited to passive matrix or Sharp HR-TFT panels with matching timing (e.g., 480×272 @ 60 Hz); higher-resolution or digital-panel interfaces require external TCON or bridge IC.
