MC9328MXLVM20 - i.MXL ARM920T MPU 200MHz 256-PBGA | NXP Semiconductors
MPN: MC9328MXLVM20 ✗ Cuối đờiMC9328MXLVM20 Tóm tắt
An applications processor (AP) is a system-on-chip (SoC) class microprocessor that integrates CPU, memory controller, and a range of peripheral interfaces into a single package, optimized for embedded multimedia products rather than general-purpose computing. The i.MXL sits within the i.MX family hierarchy (i.MX1 → i.MX21 → i.MX25 → ...), which itself derives from the ARM9-based DragonBall/Freescale MX line; this positions the part at the low-power, mid-performance tier for handheld terminals, PDAs, and industrial HMI panels of its era.
Key features include the ARM920T core with separate 16 KB instruction and 16 KB data caches, a Harvard MMU, integrated SRAM, an LCD controller with dedicated DMA, an external memory interface for SDRAM, NAND/NOR flash and PCMCIA/CF, plus USB 1.1 device, I²S audio, SPI, I²C, UART, and MMC/SD interfaces. Power management is handled via multiple on-chip voltage domains and clock-gating, supporting the low-duty-cycle workloads of battery-powered products.
Architecturally, the ARM920T core pairs a Harvard cache structure with a write buffer and a full MMU, allowing Linux and WinCE operating systems to run natively. The integrated peripherals share an AHB/APB bus fabric, with DMA channels to offload the CPU during display refresh and memory-move operations. The 200 MHz speed grade enables QVGA/VGA-resolution LCD output without external graphics hardware.
Typical applications include handheld data terminals, industrial HMI panels, portable medical instruments, point-of-sale terminals, MP3/multimedia players, and early-generation PDAs/smartphones. The wide peripheral mix makes the part a single-chip solution for products requiring display, touch input, removable storage (MMC/SD), and USB connectivity in a compact footprint.
Designers should note that the MC9328MXLVM20 has been classified Obsolete/EOL by NXP. New designs should consider the modern i.MX RT or i.MX 6/7/8 families; this part remains in service only for legacy product maintenance, repair, and refurbishment. PCB designers must follow the 14 × 14 mm MAPBGA land pattern exactly, with controlled-impedance routing for SDRAM signals.

Ghi chú thiết kế
The MAPBGA-256 package has a thermal resistance in the 20-30 C/W range depending on PCB stack-up (refer to manufacturer datasheet). At 200 MHz core clock, the i.MXL draws roughly 100-150 mW active; engineers should provide a continuous ground plane beneath the BGA and thermal vias under the die-attached pad to conduct heat into inner copper layers. For sealed enclosures with limited airflow, derate clock speed or move to a lower-power speed grade (VF15) to keep junction temperature within commercial limits.
Use a 6-layer PCB stack-up with dedicated ground and power planes beneath the MAPBGA-256 footprint. Route SDRAM signals (D0-D31, A0-A14, RAS, CAS, BA0-1, CLK, CKE) with matched length (±50 mil) and 50 Ω controlled impedance to avoid signal-integrity failures at 200 MHz. Place decoupling capacitors (0.1 µF + 10 µF) within 50 mil of every power pin. Fan-out the BGA on a 0.8 mm pitch - escape vias should be 0.2 mm laser-drilled with filled-and-capped plating for reliable assembly. Follow IPC-7351 and the Freescale/NXP reference design for the boot-mode strap configuration.
Do not assume the i.MXL is RoHS/REACH compliant - the part predates RoHS and was originally lead-bearing; lead-free reflow profiles must be qualified per JEDEC J-STD-020. Boot-mode strapping resistors on the MODE pins must match the datasheet's reset-configuration table or the part will fail to start. SDRAM initialization timing (tRCD, tRP, tMRD) must be programmed per the specific SDRAM datasheet in use - generic ARM920T code rarely works without tuning. Finally, supply-voltage sequencing between the 1.8 V core and 3.3 V I/O rails must follow the power-on order specified in the datasheet to avoid latch-up.
Thông tin tuân thủ
Part predates RoHS directive (2003); original Freescale datasheet does not declare RoHS/REACH compliance. Lead-bearing variants were standard at release. No current compliance documentation exists because the part is Obsolete. Not applicable for AEC-Q100 (automotive-grade) qualification - commercial temperature grade only.
