MCIMX31CJKN5D 개요
An applications processor (MPU) is a system-on-chip class device that, unlike a microcontroller, is designed to run full operating systems such as embedded Linux or Windows CE, offloading display, multimedia, and connectivity workloads. Within the power hierarchy of embedded processors - microcontroller -> applications processor -> SoC - the i.MX31 family sits in the mid-range segment that powered millions of consumer, industrial, automotive, and medical devices.
Key features of the i.MX31 include the ARM1136JF-S core with VFP11 floating point coprocessor, integrated image processing for camera input, LCD controller support, USB, SD/MMC interfaces, and multiple power management modes. The 532 MHz clock frequency delivers sufficient headroom for H.264 baseline video decode and graphical user interfaces typical of its generation.
Architecturally, the device combines the ARM11 core with NXP smart speed technology, multi-layer system bus fabric, and an external memory interface supporting DDR and mDDR SDRAM, NOR/NAND flash, and PCMCIA. Power supply operation is centered around 1.65 V core domains per supplier data, with sophisticated clock gating for low standby power.
Typical applications include industrial HMI panels, portable medical monitors, consumer multimedia devices, and general embedded control where a legacy i.MX31 platform must be maintained. The 457-ball footprint supports dense two-sided PCB layouts.
Design consideration: this part is listed by NXP as End of Life, so new designs should select a current i.MX generation such as i.MX 8M, while existing designs should secure stock or qualify the pin-compatible family variants listed below. Prices shown are as of 2026-08-29.

일반적인 애플리케이션
MCIMX31CJKN5D 적합 용도: 6 애플리케이션s: Industrial HMI and Control Panels, Portable Medical Monitoring Devices, Consumer Multimedia Players, Automotive Telematics and Navigation, Networking and Embedded Gateways, General Embedded and Robotics Control.
Industrial HMI and Control Panels
The i.MX31 MCIMX31CJKN5D fits industrial HMI designs because its 532 MHz ARM1136JF-S core with VFP11 accelerates 2D GUI rendering while the integrated LCD controller drives displays directly. Legacy factory panels built on i.MX31 silicon continue to run embedded Linux at the 1.65 V core domain with defined DDR/mDDR SDRAM interfaces. The 457-ball 14x14 mm LFBGA supports two-sided PCBs common in panel controllers. Since the part is EOL, sustaining this application means qualifying MCIMX31LDVKN5D or securing EOL stock from Rochester Electronics to keep production lines running.
추천
Portable Medical Monitoring Devices
Millions of i.MX31 processors, per NXP documentation, powered medical monitoring devices where moderate 532 MHz processing, low standby power from clock gating, and multimedia capability were required. The ARM1136JF-S with VFP11 handles signal processing math, while USB and SD/MMC interfaces transfer patient data. The CONSUMER FULL attribute part suits non-life-critical medical instrumentation such as patient data terminals. Designers sustaining these products should verify the EOL replacement path via MCIMX31LCVKN5D, reported by FindIC as consistent in terminals and package, requiring no circuit modification.
추천
Consumer Multimedia Players
The MCIMX31CJKN5D was architected for consumer multimedia: at 532 MHz with smart speed technology, it decodes baseline video and renders GUIs on its integrated display subsystem, using the MX31 2.0.1 silicon version with CONSUMER FULL classification. External mDDR SDRAM keeps system cost low, and the 0.5 mm pitch 457-ball package enables compact handheld layouts. The i.MX31 powered MP3/PMP class devices broadly. For service and repair of these legacy platforms, MCIMX31CVKN5D offers a parametrically similar, pin-to-pin option per Utmel comparison data.
추천
Automotive Telematics and Navigation
i.MX31 silicon served early automotive telematics and navigation units, where the 532 MHz ARM11 core ran navigation stacks and the LCD controller drove dashboard displays. The processor integrates camera input image processing useful for basic driver-assist capture in that generation. Although MCIMX31CJKN5D itself is a CONSUMER bin, automotive derivatives existed in the family. For legacy vehicle platform maintenance, EOL distributors such as Rochester Electronics stock the MPN, and family bins like MCIMX31CVMKN5D extend temperature coverage within the same 457-LFBGA footprint.
추천
Networking and Embedded Gateways
The i.MX31's USB, SD/MMC, and rich serial peripheral set made it suitable for embedded gateways and networked devices bridging field buses to Ethernet-class connectivity. The ARM1136JF-S at 532 MHz runs embedded Linux TCP/IP stacks with headroom for protocol translation, while external NOR/NAND flash stores firmware and configurations. The 1.65 V core supply with multi-layer bus fabric sustains I/O-heavy workloads. As the MPN is End of Life, gateway maintainers should inventory remaining distributors stock via Octopart, which aggregates 5 suppliers for MCIMX31CJKN5D.
추천
General Embedded and Robotics Control
Per NXP, millions of i.MX31 processors power general embedded and robotics devices, where a full OS on a single ARM11 core with VFP11 floating point handles motion planning math and sensor fusion of that era. The 457-ball 14x14 mm footprint integrates into compact controller boards, and PCMCIA/CF plus SD/MMC interfaces support field data logging. Sustaining robotics controllers qualified on MCIMX31CJKN5D is best achieved by the pin-compatible MCIMX31LDVKN5D, which FindIC lists as a complete replacement with consistent performance, terminals, and package requiring no PCB modification.

주요 차별점
- Original i.MX31 consumer bin silicon (vs MCIMX31CVMKN5D)
- Same-die drop-in sourcing continuity (vs MCIMX31LDVKN5D)
- 532 MHz top speed grade of the i.MX31 family (vs MCIMX31DJKN5D)
설계 노트
The i.MX31 uses multiple power domains centered on a 1.65 V core class supply. Design a multi-rail power tree with correct power-up sequencing between core, PLL, and I/O domains, and use the NXP i.MX31 hardware design guide layout for decoupling - one bulk plus per-ball ceramic distribution across the 457-ball field. Wrong sequencing on the DDR or PLL rails is a common field-failure cause on this generation of processors.
The 457-ball, 0.5 mm pitch BGA requires 4+ layer PCB stackup with a dedicated DDR routing layer. Match mDDR SDRAM traces within the datasheet length tolerance and reference them to a continuous ground plane. Since the part is EOL, add the family variants (MCIMX31LDVKN5D, MCIMX31LCVKN5D, MCIMX31CVKN5D) as approved alternates on the fabrication drawing now, before stock of any single MPN disappears.
Because NXP has issued discontinuance and product change notices for MCIMX31CJKN5D, do not design new products on this silicon; also verify that replacement MPNs are the exact suffix bin you expect - suffix letters encode speed grade, temperature, and package qualification, and a suffix swap (e.g., C vs LD binning) can change validated operating corners. Source only from authorized distributors or Rochester Electronics to avoid remarked EOL parts.
규정 준수 정보
RoHS compliant per distributor listing details for this consumer attribute part. REACH and halogen-free declarations should be confirmed in the current NXP product change notice since the part is EOL.
