What is a microprocessor (MPU)? A microprocessor is a CPU-centric integrated circuit that fetches instructions from external memory and executes them, typically relying on companion chips for RAM, storage, and I/O. In the embedded hierarchy, an MPU sits above a microcontroller (MCU) in performance and memory bandwidth but below an applications processor in peripheral integration. The i.MX1 family specifically bridged the gap between Freescale's earlier DragonBall MCUs and full applications processors, providing ARM9 performance with power-management features suited to battery-powered products.
Key features include the ARM920T core with a 16 KB instruction cache and 16 KB data cache, an integrated LCD controller, USB device interface, multimedia card (MMC) and Secure Digital (SD) host, CMOS sensor interface, synchronous serial port (SSI), and a 10-bit analog touch-screen controller. The device supports 16-bit and 32-bit SDRAM interfaces and a NAND flash controller with hardware ECC.
The MC9328MX1CVM15 architecture combines an ARM9TDMI integer pipeline with a separate coprocessor bus, enabling tighter integration of DSP-style operations. Internal AHB/APB bridges partition peripheral traffic to maintain CPU throughput, while the integrated PLL synthesizes core clocks from an external 12 MHz reference.
Typical applications include industrial PDAs, portable medical instrumentation, smart metering terminals, GPS handhelds, industrial HMI panels, and legacy portable data collectors. Designers typically pair the MPU with an external SDRAM, NAND flash, and a power management companion such as the MC13783.
When designing with the CVM15 grade, ensure the junction temperature remains within the -40C to +85C operating range and provide a minimum of four PCB layers with continuous power and ground planes under the BGA array for thermal dissipation and signal integrity.

Aplicaciones típicas
MC9328MX1CVM15 es adecuado para 6 aplicacións: Industrial Handheld PDA, Portable Medical Data Terminal, GPS Handheld Receiver, Smart Meter Data Collector, Industrial HMI Touch Panel, Legacy Portable Data Collector.
Industrial Handheld PDA
The MC9328MX1CVM15's 150 MHz ARM920T core and -40C to +85C industrial temperature range suit battery-powered industrial PDAs used in warehouse and field-service workflows. Its integrated LCD controller drives a QVGA TFT panel directly, while the USB device port enables docking-station connectivity. The 16/32-bit SDRAM interface and NAND flash controller (with hardware ECC) provide the memory bandwidth needed for barcode-scanning firmware and wireless-stack processing without external memory controller logic. Power dissipation is bounded by the 1.8V core and 3.3V I/O rails, both supplied by the MC13783 PMIC for tight power sequencing.
Recomendado
Portable Medical Data Terminal
Medical carts and bedside data terminals use the MC9328MX1CVM15 to run Linux-based UI stacks on a 150 MHz ARM920T while remaining within the -40C to +85C industrial temperature envelope. The integrated 10-bit touch-screen controller removes the need for an external ADC, simplifying the BOM for nurse-call terminals and patient-monitoring handhelds. SDRAM and NAND interfaces support patient-record databases stored locally, and the SSI port drives an audio codec for clinician voice notes. The MAPBGA-256 package is compatible with four-layer medical-grade PCB stack-ups.
Recomendado
GPS Handheld Receiver
GPS handhelds pair the MC9328MX1CVM15 with an external u-blox or SiRF GPS module over UART, using the ARM920T's 150 MHz performance to filter position fixes and render vector maps on an integrated TFT panel. The MMC/SD host slot accepts mapping cards, and the NAND flash controller stores base maps. USB device enables mass-storage mode for map updates, while the 32-bit SDRAM interface sustains smooth map panning. Industrial temperature range supports outdoor surveying use across all seasons.
Recomendado
Smart Meter Data Collector
Utility smart-meter data collectors benefit from the MC9328MX1CVM15's industrial temperature range and integrated LCD, USB, and UART peripherals in a compact MAPBGA-256 footprint. The ARM920T runs metering firmware that aggregates consumption readings from wireless M-Bus or PLC links, displays tariff information on a local LCD, and forwards data over the USB or UART ports to a handheld reader. Hardware ECC on the NAND interface protects logged consumption records against bit errors in the field.
Recomendado
Industrial HMI Touch Panel
Factory-floor HMI panels use the MC9328MX1CVM15 to drive a 320x240 or 640x480 TFT display via the integrated LCD controller and read resistive touch input through the on-chip 10-bit touch-screen controller. The ARM920T executes ladder-logic and trend-graphing firmware at 150 MHz with adequate headroom. The -40C to +85C range covers enclosed cabinet environments, while the SDRAM/NAND interfaces support multi-page recipe storage. The device's small MAPBGA-256 footprint enables slim bezel designs for control-room mounting.
Recomendado
Legacy Portable Data Collector
Long-life industrial programs (rail, utility, oilfield) deploy portable data collectors built around the MC9328MX1CVM15 because the part remains available through Rochester Electronics after NXP last-time-buy. The ARM920T core handles RFID reader interfaces, barcode scans, and local CSV storage on NAND with hardware ECC. The integrated USB device port supports cable-based batch uploads to legacy host applications, and the SSI port connects to a microphone for voice annotations during inspections in noisy environments.

Notas de diseño
The MC9328MX1CVM15 requires strict power sequencing: QVDD (core) must stabilize before NVDD (I/O) ramps above 1.5 V during power-up, and NVDD must fall below 1.5 V before QVDD on power-down. The MC13783 power management IC is the standard companion part and provides the required ramp ordering along with battery charging and discrete regulator outputs. Failure to observe sequencing can cause internal latch-up and permanent device damage.
The MAPBGA-256 package (17x17 mm, 1.0 mm pitch) requires a minimum four-layer PCB with continuous ground and power planes directly under the BGA array for signal integrity and thermal dissipation. Use via-in-pad with filled and plated-over vias for the inner balls to escape the array. Maintain a 50-ohm controlled impedance for the SDRAM bus; place SDRAM chips on the same side as the MPU to minimize stub lengths.
Estimated: at 150 MHz core clock with 1.8V QVDD core supply drawing roughly 150 mA active, the core dissipates approximately 0.27 W. The MAPBGA-256 package has no exposed thermal pad, so thermal dissipation depends entirely on the PCB copper pour under the array. Allocate at least 1 square inch of unbroken inner-plane copper under the MPU to keep the junction temperature rise within the 85C industrial limit.
Do not confuse the CVM15 (industrial, -40C to +85C) with the VM15 (commercial, 0 to +70C) when ordering - the suffixes differ by a single letter and lead to product returns if mismatched. Also verify that the chosen boot mode strap resistors match the desired boot source (NAND vs. NOR vs. UART) before first power-up; incorrect straps result in a non-responsive device that requires hardware rework.
