SCIMX258CVM4A 概述
Key features include hardware-accelerated LCD support up to SVGA resolution, integrated 10/100 Ethernet MAC with IEEE 1588 timestamping hardware assist, four SPIs, three I2C, and five UARTs, plus NAND Flash and DDR2 external memory controllers. Power-management features include multiple voltage domains and a Smart Direct Memory Access (SDMA) engine for low-power audio playback.
The SCIMX258CVM4A is built on a 0.13 µm process and uses the ARM926EJ-S core with 16 KB I-cache and 16 KB D-cache, supporting the ARMv5TEJ instruction set including Jazelle hardware-accelerated Java execution. Industrial temperature range (-40 C to +85 C) and NXP's product longevity program make it suitable for long-life industrial designs.
Typical applications include industrial human-machine interfaces (HMIs), building automation controllers, smart-grid energy meters, point-of-sale (POS) terminals, medical patient-monitoring equipment, and printing/scanning imaging systems. The integrated LCD controller and Ethernet MAC enable standalone networked display terminals without external graphics bridges.
When designing with this part, provide decoupling on every AVCC/VDD pin per NXP hardware design guide and verify DDR2 trace impedance - the DDR2 controller is sensitive to mismatched routing. Use the BSP from NXP for Linux support rather than legacy bare-metal code, since silicon errata are tracked in BSP release notes.

典型应用
SCIMX258CVM4A 适用于 7 应用s: Industrial Human-Machine Interface (HMI) Panel, Smart-Grid Energy Meter, Point-of-Sale (POS) Terminal, Medical Patient-Monitoring Device, Building-Automation Controller, Networked Industrial Printer/Scanner, Vehicle Telematics and Fleet-Tracking Gateway.
Industrial Human-Machine Interface (HMI) Panel
The SCIMX258CVM4A's integrated LCD controller drives SVGA-resolution touchscreens without an external graphics bridge, while its 10/100 Ethernet MAC with IEEE 1588 timestamping enables deterministic HMI-to-PLC communication. Five UARTs and three I2C buses handle multi-protocol sensor and keypad interfacing. Industrial -40 C to +85 C temperature and NXP product longevity program support long-life factory deployments where component obsolescence is a risk. NXP recommends pairing the i.MX258 with low-latency DDR2 LPDDR memory and the NXP official Linux BSP for deterministic touchscreen latency.
推荐
Smart-Grid Energy Meter
The SCIMX258CVM4A's ARM926EJ-S core with MMU runs metering algorithms (power factor, harmonics) under Linux while the integrated LCD driver displays readings directly on the panel. The 10/100 Ethernet MAC with IEEE 1588 hardware timestamping is widely used for sub-second time-synced grid telemetry where regulatory accuracy requires PTP discipline. Industrial temperature and SDMA-based audio support enable advanced metering infrastructure (AMI) deployments.
推荐
Point-of-Sale (POS) Terminal
The SCIMX258CVM4A's USB 2.0 OTG integrates fingerprint readers, NFC readers, and magnetic-stripe peripherals directly to the MPU. The integrated LCD controller and Ethernet MAC enable IP-connected terminals with on-screen customer displays. The 289-ball MAPBGA footprint allows compact all-in-one POS form factors with reliability across the commercial -40 C to +85 C industrial range. NXP Linux BSP provides EMV/PCI PTS middleware support.
推荐
Medical Patient-Monitoring Device
The SCIMX258CVM4A runs a real-time patch on the ARM926EJ-S while a Linux UI handles touchscreen interaction, supporting vital-sign displays of ECG, SpO2, and respiration waveforms. The MMU enables memory protection between the real-time patch and the rich OS, addressing IEC 62304 medical-device software-process requirements. -40 C to +85 C and NXP product-longevity support a 10-year plus deployment lifecycle in clinical environments.
推荐
Building-Automation Controller
The SCIMX258CVM4A drives a wall-mounted touchscreen, manages BACnet/Modbus traffic over Ethernet, and runs the building-management Linux stack on the same MPU. The integrated LCD controller and SDMA audio engine deliver both visual feedback and intercom capability without external DSP. The 289-ball MAPBGA footprint supports thin wall-mount enclosure designs common in commercial HVAC and access-control panels.
推荐
Networked Industrial Printer/Scanner
The SCIMX258CVM4A's four SPIs handle image-sensor and stepper-motor drivers, while the integrated LCD drives the operator panel, and the 10/100 Ethernet MAC delivers scan-to-network/email capability. The DDR2 controller supports the image-line buffer at high printer resolutions without external bandwidth bridges. NXP's industrial product-longevity program keeps the BOM available for the printer's 7-10 year support window.
推荐
Vehicle Telematics and Fleet-Tracking Gateway
The SCIMX258CVM4A's ARM926EJ-S runs the telematics application while CAN bridges connect to vehicle networks. Industrial -40 C to +85 C temperature and the SDMA engine for low-latency audio support audio-prompts for driver alerts. The 289-ball MAPBGA package fits compact in-cabin enclosures and the integrated Ethernet MAC provides fleet backhaul without an external processor.

关键差异点
- Higher integration than discrete solutions （对比 SCIMX251CVM4A (lower-speed variant))
- Drop-in compatibility within i.MX25 family （对比 SCIMX255CVM4A)
- Industrial product-longevity supply （对比 SCIMX257CVM4A)
设计说明
The i.MX25 SCIMX258CVM4A implements multiple voltage domains: 1.2 V for ARM core, 1.8 V for DDR2, and 3.3 V for I/O. Estimate: total power at 400 MHz is approximately 0.9 W with all peripherals active; at idle the SDMA-only playback mode drops this to ~150 mW. Use a dedicated LDO for the 1.2 V core rail capable of 600 mA dynamic load - the core voltage must be sequenced first per NXP hardware design guide to avoid in-rush latch-up. Place 22 µF + 0.1 µF decoupling on every VDD/AVCC BGA ball within 2 mm trace length.
The 289-ball MAPBGA package requires microvia PCB technology (8-layer Class 3 stack-up with 0.4 mm pitch escape). Estimate: total component area roughly 14 mm × 14 mm. Route the DDR2 interface first with 50 Ω single-ended / 100 Ω differential impedance per JEDEC specifications; route USB DP/DN as a 90 Ω differential pair on the top layer with no splits. Add ground vias adjacent to every high-speed signal via to minimize inductance.
At sustained 400 MHz operation, the SCIMX258CVM4A dissipates approximately 0.9 W, requiring a thermal pad area of at least 6 mm × 6 mm of 1 oz copper to maintain junction temperature below 100 C at +85 C ambient. For sealed industrial enclosures, estimate that derating to 350 MHz reduces dissipation to ~0.7 W and may eliminate the need for thermal vias. Always verify thermally in the actual housing with worst-case corner software workloads.
Do not confuse this part SCIMX258CVM4A with the i.MX6 series - the i.MX25 uses an ARM9 core with DDR2 controller, not the ARM Cortex-A9 with LPDDR2 used in i.MX6. Mis-mating the BSP causes boot failures. Verify DDR2 timing parameters in the hardware design guide; mismatched CAS latency is a common cause of boot loops. Use only NXP-released BSPs - third-party patches rarely cover silicon errata.
合规信息
RoHS compliant per NXP product page; lead-free MAPBGA package; AEC-Q100 qualification not applicable for industrial-grade MPUs. Consumer i.MX25 variants exist for -20 C to +70 C environments but are not AEC-Q100 qualified for automotive use.
