Product details
Overview
MCIMX233DJM4CR2 from NXP is an ARM926EJ-S™-based 454 MHz multimedia applications processor with integrated DC-DC power management, stereo analog audio ADC/DAC + headphone amplifier, 1.5 W mono speaker amplifier, 12-bit LRADC, and LCDIF supporting 24-bit VGA (640×480). It targets cost-sensitive portable media players and graphical HMI panels powered by single Li-Ion battery.
For engineers reviewing the MCIMX233DJM4CR2 datasheet, MCIMX233DJM4CR2 pinout, MCIMX233DJM4CR2 application, or MCIMX233DJM4CR2 equivalent, key selection considerations include its 169-ball MAPBGA package, -10°C to +70°C industrial temperature range, integrated 20-bit BCH NAND ECC, PXP pixel pipeline for hardware-accelerated display post-processing, and dual I2S interfaces for multi-audio-path designs.
Technical Context
The MCIMX233DJM4CR2 implements an Arm926EJ-S core at up to 454 MHz with 16 KB I-cache and 16 KB D-cache, coupled with on-chip 32 KB SRAM and boot ROM. Its integrated power management includes a 4-channel DC-DC converter, Li-Ion battery charger, and silicon temperature/speed sensors.
It supports external DDR1/mDDR memory and NAND flash with hardware 20-bit BCH or 8-bit Reed-Solomon error correction. The LCD interface provides both 8-bit serial and 24-bit parallel modes, while the Pixel Processing Pipeline (PXP) enables hardware scaling, alpha blending, rotation, and color space conversion without CPU overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multimedia applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX233CJM4CR2 | Same 169-ball MAPBGA package and feature set, but rated for -40°C to +85°C extended temperature range | Required for industrial outdoor or automotive cabin-mounted HMIs exposed to wider thermal cycling | Select when operating ambient exceeds +70°C or requires AEC-Q200-aligned thermal qualification |
| i.MX283 (MCIMX283CVM4B) | ARM9 @ 454 MHz, but adds crypto acceleration (AES/SHA), Ethernet MAC, and enhanced LCDIF with overlay planes; larger 289-ball BGA | Targets secure connected devices needing TLS offload, wired network, or multi-layer GUI compositing | Choose when cryptographic services, 10/100 Ethernet, or advanced display layering are mandatory |
Compared with MCIMX233CJM4CR2, the MCIMX233DJM4CR2 trades extended temperature tolerance for lower cost in commercial indoor applications; versus i.MX283, it offers identical CPU performance and media features at reduced package size and BOM cost-but lacks crypto engines and Ethernet, making it optimal for cost-constrained, battery-powered UI endpoints.

FAQ
What is the operating temperature range for MCIMX233DJM4CR2?
The MCIMX233DJM4CR2 is specified for industrial operation from -10°C to +70°C. This range supports deployment in enclosed consumer devices such as portable media players and indoor home automation panels where ambient conditions remain within typical room-temperature envelopes. It is not qualified for extended temperature environments like automotive under-hood or outdoor industrial enclosures-those require the MCIMX233CJM4CR2 variant.
Does MCIMX233DJM4CR2 support NAND flash with hardware error correction?
Yes, MCIMX233DJM4CR2 includes a dedicated hardware ECC engine supporting both 20-bit BCH and 8-bit Reed-Solomon correction. This enables reliable boot and data storage on SLC, MLC, and managed NAND devices without software overhead. The controller handles correction transparently during read/write operations, improving NAND endurance and field failure rates in high-volume consumer products.
Can MCIMX233DJM4CR2 drive a 24-bit RGB LCD display directly?
Yes, MCIMX233DJM4CR2's LCDIF supports 24-bit parallel RGB output at VGA resolution (640×480) with programmable timing, polarity, and data format. When used with the integrated PXP graphics accelerator, it can perform hardware scaling and alpha blending-reducing CPU load and DRAM bandwidth. No external timing controller or level shifter is needed for standard 3.3 V LVCMOS RGB interfaces.
How many I2S interfaces does MCIMX233DJM4CR2 provide, and what are their roles?
MCIMX233DJM4CR2 integrates two independent I2S interfaces. I2S1 is typically used for primary audio playback (e.g., to a DAC or headset), while I2S2 supports simultaneous recording or secondary playback (e.g., speakerphone path). Both support 16/24-bit stereo at sample rates up to 96 kHz, enabling full-duplex audio in VoIP handsets or multi-zone audio accessories without time-division multiplexing.
Is there an integrated speaker amplifier in MCIMX233DJM4CR2, and what is its output capability?
Yes, MCIMX233DJM4CR2 includes a Class-D mono speaker amplifier delivering 1.5 W into 4 Ω or 8 Ω loads. It accepts digital audio via I2S or analog input via dedicated line-in pins, and includes volume control, mute, and thermal shutdown protection. This eliminates the need for external amplifier ICs in portable speakers, media players, and smart remotes-reducing BOM cost and PCB area.
