Product details
Overview
MCIMX233CAG4C from NXP is a 32-bit ARM926EJ-S™ multimedia applications processor operating at up to 454 MHz, integrating power management, stereo ADC/DAC with headphone amplifier, 1.5 W mono speaker amplifier, LCDIF (8-bit serial), and 12-bit LRADC - deployed in portable media players and graphical HMI panels for industrial applications.
For engineers reviewing the MCIMX233CAG4C datasheet, MCIMX233CAG4C pinout, MCIMX233CAG4C application, or MCIMX233CAG4C equivalent, key selection considerations include its -40°C to +85°C industrial temperature range, 128-pin LQFP package, single debug + single application UART, 2 A/D channels, and absence of mono speaker amplifier and dual I2S compared to the 169 BGA variant.
Technical Context
The MCIMX233CAG4C implements an Arm926EJ-S core with 16 KB I-cache and 16 KB D-cache, clocked to 454 MHz, and integrates on-die DC-DC converters supporting Li-Ion battery input and USB/wall adapter direct power. It boots from NAND flash with hardware BCH 20-bit or Reed-Solomon 8-bit ECC support.
Its multimedia subsystem includes an LCD interface limited to 8-bit serial mode (no 24-bit parallel), a pixel processing pipeline (PXP) for display frame pre-processing, and analog audio I/O with stereo ADC/DAC plus headphone amplification - but excludes mono speaker amplifier and TV encoder found in the BGA variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM926EJ-S™ @ 454 MHz with 16 KB I-cache and 16 KB D-cache - enables real-time multimedia execution without external cache. |
| Operating Temperature | -40°C to +85°C - qualified for industrial embedded environments including factory HMIs and home automation gateways. |
| Package | 128-pin LQFP - supports low-cost PCB manufacturing with ≤4 layers, no BGA reflow requirements. |
| Memory Interface | Single chip enable, 64 MB address space - limits external DDR1/mDDR and NAND capacity vs. BGA variant's dual CE/128 MB. |
| Audio Interfaces | Stereo ADC/DAC + headphone amp; no mono speaker amp or TV encoder - targets audio peripherals and VoIP handsets, not standalone media playback. |
| Serial Peripherals | 1 debug UART + 1 application UART; SSP1 (4-bit); 2× I²C; 2× SPI - sufficient for sensor hub + display + USB host control in cost-sensitive devices. |
| Analog Inputs | 2-channel 12-bit LRADC - supports rotary encoder, battery voltage monitoring, and simple touch sensing (no dedicated touchscreen controller). |
Pinout & Package
MCIMX233CAG4C is housed in a 128-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions align with the i.MX233 LQFP signal mapping defined in NXP reference manual IMX23RM, Rev. 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | I/O supply rail | 3.3 V tolerant; powers all GPIO, UART, SPI, I²C, and LCDIF pins - requires local 3.3 V regulation. |
| VDDA | Analog supply | Separate 3.3 V input for ADC/DAC and audio blocks - must be filtered to minimize noise coupling into analog paths. |
| VDDRTC | Real-time clock supply | Backup 3.3 V or coin-cell input for RTC operation during main power loss - enables calendar/timekeeping in sleep modes. |
| USB_DP / USB_DM | USB 2.0 HS PHY differential pair | Integrated transceiver supports host/device mode; requires 27 Ω series resistors and 15 kΩ pull-down on DM for device enumeration. |
| LRADC_IN0 / LRADC_IN1 | Low-resolution analog inputs | Dedicated 12-bit inputs for battery sensing, rotary encoder, or resistive touch - no internal reference; uses VDDA as reference. |
| LCD_D0–D7 | LCD data bus (serial mode) | 8-bit multiplexed interface for 8-bit serial LCD panels only - no support for 16-/24-bit parallel RGB or TFT timing signals. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated DC-DC converter with 4 LDO outputs | Reduces external PMIC count; supplies core, memory, I/O, and analog rails from single Li-Ion or 5 V source - cuts BOM cost by ≥3 components. |
| Stereo audio ADC/DAC + headphone amplifier | Enables full-duplex voice capture/playback in VoIP handsets or audio remotes without codec IC - eliminates external audio path components. |
| Hardware PXP graphics accelerator | Performs alpha blending, rotation, scaling, and color-space conversion off-CPU - reduces CPU load by ~40% during UI rendering on VGA-resolution displays. |
| NAND boot with 20-bit BCH ECC | Supports reliable boot from SLC/MLC NAND; corrects up to 20 bit errors per 512-byte sector - extends flash lifetime in unmanaged NAND deployments. |
| Secure boot with AES-128 & SHA-1 | Verifies signed firmware images using OTP-stored keys - prevents unauthorized code execution in industrial HMI and home gateway applications. |

FAQ
What is the maximum operating frequency of the MCIMX233CAG4C?
The MCIMX233CAG4C features an ARM926EJ-S™ core rated for operation up to 454 MHz. This frequency is guaranteed across its full industrial temperature range (-40°C to +85°C) and supported by on-chip PLL and dynamic voltage scaling. The MCIMX233CAG4C achieves this performance while maintaining low active power consumption, enabling sustained operation in thermally constrained portable designs.
Does the MCIMX233CAG4C support NAND flash boot with error correction?
Yes, the MCIMX233CAG4C supports booting directly from NAND flash with hardware-accelerated error correction. It implements both 20-bit BCH and 8-bit Reed-Solomon ECC engines, correcting up to 20 bit errors per 512-byte sector. This capability ensures robust firmware loading from SLC, MLC, or managed NAND devices - critical for long-life industrial deployments where flash wear is a concern. The MCIMX233CAG4C does not require external ECC logic.
What audio interfaces are integrated into the MCIMX233CAG4C?
The MCIMX233CAG4C integrates stereo analog audio ADC and DAC with dedicated headphone amplifier circuitry, supporting 16-bit/44.1 kHz audio I/O. It also includes S/PDIF digital output and a Serial Audio Interface (I2S) - though only one I2S channel is enabled in the 128 LQFP package. Notably, the MCIMX233CAG4C omits the mono speaker amplifier and TV encoder present in the 169 BGA variant, targeting compact audio peripherals rather than standalone media playback.
Can the MCIMX233CAG4C drive a standard VGA-resolution LCD panel?
The MCIMX233CAG4C's LCD interface supports up to VGA (640×480) resolution, but only in 8-bit serial mode - not 24-bit parallel RGB. It lacks the 24-bit parallel LCDIF signals available in the 169 BGA variant. Therefore, it can drive serial-interface TFTs or character LCDs compatible with 8-bit multiplexed timing, but cannot natively drive standard parallel RGB VGA panels without external bridge ICs. The MCIMX233CAG4C relies on its PXP engine for display preprocessing to maintain UI responsiveness within this constraint.
What is the package type and thermal specification of the MCIMX233CAG4C?
The MCIMX233CAG4C is supplied in a 128-pin LQFP package measuring 20 mm × 20 mm with 0.5 mm lead pitch and an exposed thermal pad. Its specified operating junction temperature range is -40°C to +85°C, and it is characterized for industrial-grade reliability. The LQFP format avoids BGA assembly complexity while providing adequate thermal dissipation for typical 454 MHz ARM9 workloads - making the MCIMX233CAG4C suitable for cost-sensitive, thermally moderate embedded applications.
