Product details
Overview
MCIMX233DAG4B from NXP is an ARM926EJ-S™-based 454 MHz multimedia applications processor in 128-pin LQFP, integrating DC-DC power management, stereo ADC/DAC with headphone amplifier, 12-bit LRADC, USB 2.0 HS PHY, and LCDIF for VGA (640×480) displays - deployed in portable media players and graphical remote controls.
For engineers reviewing the MCIMX233DAG4B datasheet, MCIMX233DAG4B pinout, MCIMX233DAG4B application, or MCIMX233DAG4B equivalent, key selection considerations include its -10°C to +70°C industrial temperature range, 128 LQFP package with 1 UART, 2 A/D channels, no mono speaker amplifier, and support for DDR1/mDDR/NAND with 8-bit Reed-Solomon ECC - critical for cost-sensitive HMI and embedded display systems.
Technical Context
The MCIMX233DAG4B implements an Arm926EJ-S core at up to 454 MHz with 16 KB I-cache and 16 KB D-cache, paired with on-chip 32 KB SRAM and boot ROM. Its integrated DC-DC converter delivers multiple regulated outputs directly from a single Li-Ion battery or 5 V USB/wall source, including battery charging capability and silicon temperature/speed sensing.
It supports external memory via one chip enable (64 MB limit), 8-bit NAND data width over GPMI, 8-bit serial LCDIF only (no 24-bit parallel), and lacks dedicated rotary encoder or second I2S interface - distinguishing it from the 169 BGA variants. Real-time clock uses 24 MHz reference only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm926EJ-S™ @ 454 MHz - enables real-time multimedia processing without external co-processor |
| Memory Interface | Single CE DDR1/mDDR + NAND with 8-bit Reed-Solomon ECC - supports reliable boot and storage in space-constrained designs |
| Audio Subsystem | Stereo ADC/DAC + headphone amp + S/PDIF Tx - provides full analog/digital audio I/O without codec IC |
| Power Management | Integrated multi-output DC-DC + Li-Ion charger - eliminates external PMIC and reduces BOM count by ≥3 components |
| Display Support | LCDIF with 8-bit serial interface only - drives small VGA panels but excludes high-speed parallel RGB interfaces |
| Connectivity | USB 2.0 HS PHY + 1 debug + 1 application UART + 2 SPI + I2C - sufficient for basic peripheral and host/device USB bridging |
| Temperature Range | -10°C to +70°C - qualified for commercial/industrial indoor environments, not extended automotive or outdoor use |
Pinout & Package
MCIMX233DAG4B is housed in a 128-pin LQFP package (20 mm × 20 mm, 0.5 mm pitch) with exposed thermal pad. Pin functions are defined per NXP reference schematic and i.MX233 Hardware Developer's Guide Rev. 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | I/O supply rail | 3.3 V tolerant; powers GPIO, USB, UART, SPI - must be decoupled locally |
| VDDA | Analog supply | Separate 3.3 V input for ADC/DAC/amp - requires low-noise filtering |
| VDDRTC | Real-time clock supply | Backup domain powered independently - enables RTC operation during main power-off |
| USB_DP / USB_DM | USB 2.0 differential pair | Integrated PHY eliminates need for external transceiver; supports host/device mode |
| SDA / SCL | I2C bus signals | Open-drain, 3.3 V - used for PMIC configuration, EEPROM, or sensor communication |
| LRADC_IN0 / LRADC_IN1 | Low-resolution analog inputs | 12-bit, 1 MS/s sampling - supports touch buttons, battery voltage monitoring, or potentiometer input |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar multimedia applications processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCIMX233DJM4C | 169-ball MAPBGA, 0.8 mm pitch; adds 2nd I2S, rotary encoder, 5 PWM, 6 A/D channels, 24/32 kHz RTC | Supports touchscreen, richer audio I/O, and higher-resolution displays requiring parallel LCDIF | Select when needing touch interface, dual audio paths, or extended peripheral count - requires 6-layer PCB |
| i.MX283 (MCIMX283CVM4B) | ARM9 @ 454 MHz, same package; adds Ethernet MAC, CAN, enhanced security (OTP, AES-128), and 10/100 PHY option | Targeted at networked industrial gateways and secure HMI where wired connectivity or crypto acceleration is required | Choose for Ethernet/CAN integration or secure boot - not drop-in; differs in pinout, power sequencing, and peripheral mapping |
Compared with MCIMX233DAG4B, MCIMX233DJM4C enables richer multimedia I/O at higher PCB complexity, while i.MX283 adds networking and security features at the cost of increased power and non-interchangeable pinout - neither is pin-compatible, and both require board redesign.

FAQ
What is the maximum operating frequency of the MCIMX233DAG4B?
The MCIMX233DAG4B features an Arm926EJ-S™ core rated for operation up to 454 MHz under specified thermal and voltage conditions. This frequency is achievable with proper PCB thermal design and stable 1.2 V core supply. The MCIMX233DAG4B does not support dynamic frequency scaling beyond this fixed maximum, and all timing-critical peripherals (USB, LCDIF, NAND) are validated at this clock rate.
Does the MCIMX233DAG4B support touchscreen functionality?
No, the MCIMX233DAG4B does not include a touchscreen controller. Unlike the 169 BGA variants (e.g., MCIMX233DJM4C), the 128 LQFP package omits the dedicated touch screen interface block. Touchscreen support requires external resistive/capacitive controller ICs or migration to a BGA variant - the MCIMX233DAG4B retains only general-purpose GPIO and LRADC for button or slider input.
What NAND flash types and error correction does the MCIMX233DAG4B support?
The MCIMX233DAG4B supports SLC, MLC, and managed NAND devices via its GPMI interface with hardware-accelerated 8-bit Reed-Solomon ECC. It does not support the 20-bit BCH ECC available on 169 BGA variants. NAND boot is fully supported, and the ROM bootloader validates ECC before loading firmware - essential for field reliability in consumer devices using commodity NAND.
Can the MCIMX233DAG4B drive a VGA-resolution display?
Yes, the MCIMX233DAG4B's LCDIF supports VGA resolution (640×480) but only in 8-bit serial mode - not 24-bit parallel. This limits bandwidth and excludes high-refresh-rate or RGB888 interfaces. For VGA output, external shift registers or serial-to-parallel bridge ICs may be needed. The MCIMX233DAG4B does not support HDMI, LVDS, or MIPI-DSI outputs.
Is the MCIMX233DAG4B pin-compatible with other i.MX233 variants?
No, the MCIMX233DAG4B is not pin-compatible with any other i.MX233 variant. Its 128 LQFP footprint differs electrically and physically from the 169 MAPBGA packages (e.g., MCIMX233DJM4C). Signal mapping, power rail requirements, and thermal pad configuration are unique to the LQFP variant - PCB layout cannot be reused across package types.
