NXP Semiconductors MC9328MXSCVP10R2

Overview

MC9328MXSCVP10R2 from NXP Semiconductors (formerly Freescale) is an ARM920T™-based applications processor delivering 100 MHz core performance with integrated SDRAM controller, LCD controller, USB Device, UARTs, SPI, I²C, PWM, and DMA. It operates at 1.7–1.9 V core voltage and supports 1.7–3.3 V I/O, targeting battery-powered portable systems requiring real-time OS support and low-power operation.

For engineers reviewing the MC9328MXSCVP10R2 datasheet, MC9328MXSCVP10R2 pinout, MC9328MXSCVP10R2 application, or MC9328MXSCVP10R2 equivalent, key selection considerations include its 225-ball MAPBGA package, -40°C to +85°C industrial temperature grade, integrated peripheral set for display/audio/communication subsystems, and power management features enabling extended runtime in handheld medical, PDA, and point-of-sale devices.

Technical Context

The MC9328MXSCVP10R2 implements the ARM920T core with Harvard architecture, MMU support, and 16 KB instruction + 16 KB data caches. Its DPLL clock module generates system clocks from 32 kHz or 16 MHz crystal inputs, while the External Interface Module (EIM) provides configurable timing for NOR/NAND flash, SRAM, and peripherals via programmable chip-selects and burst control signals.

Functional integration includes a 16-bit LCD controller supporting TFT panels with dedicated Sharp-panel signals (SPL_SPR, PS, CLS, REV), dual UARTs with full modem control (RTS/CTS/DSR/RI/DCD/DTR), and a synchronous serial interface configurable as I²S or SSI for audio codec interfacing - all operating under dynamic power gating and multiple low-power standby modes.

Key Specifications

Pinout & Package

MC9328MXSCVP10R2 uses a 225-contact MAPBGA (Moisture-Sensitive Plastic Ball Grid Array) package per Case 1304B-01, with 1.0 mm ball pitch and 13 × 13 mm footprint. Power domains are segregated: QVDD/QVSS for core logic, NVDD/NVSS for digital I/O groups (NVDD1–NVDD4), AVDD/AVSS for analog functions (crystal, USB AFE), and dedicated TRISTATE test control.

Manufacturer

NXP Semiconductors is a global semiconductor leader focused on secure connectivity solutions for automotive, industrial, and IoT applications, formed from the spin-off of Freescale Semiconductor in 2015.

The i.MX family, including MC9328MXSCVP10R2, was designed specifically for cost-sensitive, battery-powered portable electronics requiring ARM compatibility, integrated peripherals, and robust power management - targeting markets where size, power, and bill-of-materials matter more than peak compute performance.

FAQ

What is the maximum operating frequency of the MC9328MXSCVP10R2?

The MC9328MXSCVP10R2 features an ARM920T core rated for operation up to 100 MHz. This frequency is guaranteed across the full -40°C to +85°C industrial temperature range when powered with QVDD between 1.7 V and 1.9 V. The core achieves this speed using internal PLL multiplication from either the 32 kHz or 16 MHz crystal inputs, with timing validated per AC specifications in the official datasheet Rev. 3.

Does the MC9328MXSCVP10R2 support external SDRAM, and what configurations are validated?

Yes, the MC9328MXSCVP10R2 includes a dedicated SDRAM controller supporting 16-bit wide x 1–4 banks, with validated operation up to 128 MB using standard 64 Mbit × 16-bit SDRAM parts. The controller provides programmable timing registers for CAS latency, tRCD, tRP, and refresh intervals, and supports both non-interleaved and interleaved addressing modes via SDBA/SDIBA signals. Reference designs confirm stable operation at 100 MHz core clock with 133 MHz SDRAM bus.

What LCD interface capabilities does the MC9328MXSCVP10R2 provide?

The MC9328MXSCVP10R2 integrates a 16-bit parallel LCD controller (LCDC) supporting passive and active matrix TFT panels up to 1024×768 resolution. It delivers dedicated timing signals including FLM/VSYNC, LP/HSYNC, LSCLK, and Sharp-specific controls (SPL_SPR, PS, CLS, REV, CONTRAST). The controller operates independently of the CPU via DMA, enabling continuous display refresh while the ARM920T executes application code - critical for responsive user interfaces in portable devices.

Is the MC9328MXSCVP10R2 pin-compatible with other i.MX processors like the i.MX21?

No, the MC9328MXSCVP10R2 is not pin-compatible with i.MX21 or later i.MX families. It uses a unique 225-ball MAPBGA package (Case 1304B-01) with signal assignments and power domain partitioning specific to the i.MXS generation. While functional blocks like UART, SPI, and USB appear across generations, pin locations, voltage domains (e.g., separate NVDD1–NVDD4 rails), and multiplexing schemes differ significantly - requiring full PCB redesign for migration to i.MX21 or newer variants.

What power management features are implemented in the MC9328MXSCVP10R2?

The MC9328MXSCVP10R2 implements four low-power states: NORMAL, WAIT, STOP, and DEEP-SLEEP. In DEEP-SLEEP mode, core logic is gated while RTC, GPIO wakeup, and USB suspend detection remain active - drawing only 25–60 μA depending on voltage and temperature. The DPLL supports dynamic clock gating per peripheral, and the reset module integrates POR, external RESET_IN, and watchdog-initiated reset with configurable delay. These features enable multi-week battery life in intermittently active portable applications.
