NXP Semiconductors MC9328MXSCVP10

Overview

MC9328MXSCVP10 from Freescale Semiconductor is an ARM920T™-based applications processor operating at 100 MHz, featuring integrated SDRAM controller, LCD controller, USB Device, UARTs, SPI, I²C, PWM, and DMA. Packaged in a 225-ball MAPBGA (Case 1304B-01), it targets low-power portable devices requiring open OS support and real-time peripheral integration - such as point-of-sale terminals and medical instrumentation.

For engineers reviewing the MC9328MXSCVP10 datasheet, MC9328MXSCVP10 pinout, MC9328MXSCVP10 application, or MC9328MXSCVP10 equivalent, key selection criteria include its −40°C to +85°C industrial temperature grade, 1.7–1.9 V core supply, 225-ball BGA package with signal multiplexing, and integrated peripherals enabling compact embedded designs without external bridge logic.

Technical Context

The MC9328MXSCVP10 implements the ARM920T™ core with MMU, Harvard bus architecture, and tightly coupled memory interfaces. Its External Interface Module (EIM) supports asynchronous SRAM, NOR flash, and burst-mode synchronous memories via configurable chip-selects, byte strobes, and DTACK handshake.

It integrates a DPLL-based clock generation system for flexible frequency synthesis, dual 32-bit general-purpose timers with capture/compare, and a programmable LCD controller supporting 16-bit RGB TFT panels with Sharp HR-TFT timing modes. Power management includes multiple low-power states and dynamic voltage scaling support within its 1.7–1.9 V QVDD range.

FAQ

What is the maximum operating frequency of the MC9328MXSCVP10?

The MC9328MXSCVP10 operates at a maximum core frequency of 100 MHz using the ARM920T™ processor core. This frequency is sustained under recommended operating conditions: QVDD = 1.7–1.9 V, ambient temperature −40°C to +85°C, and proper power sequencing. The DPLL generates all internal clocks from either a 32 kHz or 4–16 MHz reference source.

Does the MC9328MXSCVP10 support external SDRAM, and what densities are compatible?

Yes, the MC9328MXSCVP10 includes an integrated SDRAM controller supporting standard x16/x32 SDRAM devices. It is compatible with densities ranging from 16 MB to 128 MB, using MA[9:0], SDBA[4:0], and control signals (RAS/CAS/SDWE/SDCLK). Timing parameters are programmable via SDRAMC registers to match vendor-specific specifications.

What LCD interface capabilities does the MC9328MXSCVP10 provide?

The MC9328MXSCVP10 features a dedicated LCD controller (LCDC) supporting 16-bit RGB parallel output (LD[15:0]), frame/line sync (FLM/VSYNC, LP/HSYNC), and Sharp HR-TFT-specific signals (SPL_SPR, PS, CLS, REV). It drives passive and active matrix TFT panels directly without external timing generators or level shifters when powered at 3.3 V NVDD.

Is the MC9328MXSCVP10 pin-compatible with other i.MX family members like the MC9328MXSVP10?

No, the MC9328MXSCVP10 is not pin-compatible with MC9328MXSVP10. While both share the same 225-ball MAPBGA package and core functionality, the CVP10 variant is rated for −40°C to +85°C operation and uses different thermal and electrical validation - resulting in distinct ball-level DC characteristics and power sequencing requirements that preclude mechanical interchangeability.

What power supply sequencing is required for reliable startup of the MC9328MXSCVP10?

MC9328MXSCVP10 requires strict power sequencing: NVDD must ramp to ≥1.8 V before QVDD begins rising, to prevent forward biasing of internal protection diodes. AVDD and QVDD may ramp simultaneously after NVDD stabilization. Failure to observe this sequence risks latch-up or permanent damage, as specified in Freescale Application Note AN2537.
