NXP Semiconductors MCIMX233DAG4C

Overview

MCIMX233DAG4C from NXP is a single-core ARM926EJ-S microprocessor operating at 454 MHz, featuring 128 KB on-chip SRAM, integrated LCD controller (up to WXGA), 8-channel 12-bit ADC with touchscreen support, and dual USB 2.0 OTG controllers - deployed in industrial HMIs and portable medical devices requiring deterministic real-time response and low-power operation.

For engineers reviewing the MCIMX233DAG4C datasheet, MCIMX233DAG4C pinout, MCIMX233DAG4C application, or MCIMX233DAG4C equivalent, key selection criteria include its ARM926EJ-S core architecture, 128 KB embedded SRAM, 8-channel 12-bit ADC with touch interface, dual USB 2.0 OTG capability, and 14 × 14 mm 208-pin BGA package with 0.65 mm pitch.

Technical Context

The MCIMX233DAG4C implements an ARM926EJ-S core with Jazelle Java acceleration and Thumb-2 instruction set support, paired with tightly coupled memory subsystems including 128 KB SRAM and configurable boot ROM. It integrates dedicated peripherals for human-machine interaction: LCD controller supporting RGB parallel output up to 1024×768, resistive touchscreen interface, and dual USB 2.0 OTG PHYs with internal transceivers.

Power management is handled by on-die regulators and dynamic voltage/frequency scaling (DVFS), enabling operation across industrial temperature range (−40°C to +85°C). All peripheral clocks are independently gated, and the device supports multiple low-power states including WAIT and STOP modes with wake-up via GPIO, RTC, or USB events.

FAQ

What is the maximum display resolution supported by the MCIMX233DAG4C?

The MCIMX233DAG4C supports parallel RGB output up to WXGA resolution (1366 × 768 pixels) through its integrated LCD controller. This capability enables direct drive of industrial-grade TFT panels without external timing controllers or frame buffer compression, making it ideal for compact HMI displays where board space and BOM cost are constrained.

Does the MCIMX233DAG4C include hardware cryptographic acceleration?

No, the MCIMX233DAG4C does not include hardware cryptographic accelerators such as AES, SHA, or RSA engines. Its security features are limited to secure boot with OTP fuses and tamper-resistant RTC. For applications requiring hardware-accelerated cryptography, the pin-compatible i.MX283 is the recommended alternative with full FIPS-compliant crypto block integration.

What is the function of the TSI_XP/YP pins on the MCIMX233DAG4C?

The TSI_XP[3:0] and TSI_YP[3:0] pins on the MCIMX233DAG4C provide dedicated analog inputs for 4-wire resistive touchscreen interfaces. These pins connect directly to X-plate and Y-plate electrodes, enabling on-chip voltage measurement, coordinate interpolation, and touch debounce - eliminating the need for external ADC or touchscreen controller ICs.

Can the MCIMX233DAG4C operate without external SDRAM?

Yes, the MCIMX233DAG4C can operate entirely from its 128 KB on-chip SRAM, supporting bootloader execution, RTOS kernel, and application code without external memory. This capability simplifies system design, reduces power consumption, and enhances reliability in space-constrained or high-vibration environments where SDRAM solder joints may be prone to failure.

What USB configurations are supported by the MCIMX233DAG4C?

The MCIMX233DAG4C integrates two independent USB 2.0 OTG controllers, each with a built-in PHY. It supports simultaneous USB device and host roles - for example, acting as a USB HID keyboard while enumerating a USB flash drive as a host. No external transceivers or hub logic are required, and both ports support full-speed (12 Mbps) operation with cable detection.
