Overview
MCF52274CLU120 from NXP Semiconductors (formerly Freescale) is a ColdFire® Version 2 RISC microprocessor with integrated EMAC, 128 KB SRAM, 8 KB configurable cache, and FlexCAN 2.0B interface - designed for industrial HMI, embedded control, and LCD-based human-machine interfaces operating at up to 120 MHz core clock.
For engineers reviewing the MCF52274CLU120 datasheet, MCF52274CLU120 pinout, MCF52274CLU120 application, or MCF52274CLU120 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative microprocessors for migration or second-sourcing decisions.
Technical Context
The MCF52274CLU120 implements a ColdFire V2 core with hardware EMAC acceleration and crossbar switch (XBS) architecture enabling concurrent access to peripherals and SRAM by multiple bus masters. It supports booting from SPI-compatible flash/EEPROM/FRAM and integrates a 12-bit LCD controller with up to 800×600 pixel support.
Its memory subsystem includes 128 KB on-chip SRAM and an 8 KB configurable cache (instruction-only, data-only, or split). The device features a 16-channel DMA controller, 4 × 32-bit timers with DMA support, FlexCAN 2.0B, USB 2.0 On-The-Go, and dual programmable interrupt controllers (PIT).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF52277CVM160 | Higher core clock (166.67 MHz), 196 MAPBGA package, 18-bit LCD controller, same peripheral set. | Supports higher-resolution displays (e.g., 1024×600) and compute-intensive tasks; requires different PCB layout and thermal design. | Select when >120 MHz performance or 18-bit color depth is required; not pin-compatible with MCF52274CLU120. |
| i.MX283 (NXP) | ARM926EJ-S core, 454 MHz, integrated PMIC, Ethernet MAC, but no native FlexCAN or LCD controller. | Targets Linux-based gateways with networking; lacks direct LCD/CAN integration - requires external transceivers and display bridges. | Choose for higher OS performance and connectivity; accept added BOM complexity for CAN/LCD functionality. |
Compared with MCF52277CVM160 and i.MX283, the MCF52274CLU120 offers optimal balance of deterministic real-time control, integrated display/CAN interfaces, and LQFP manufacturability - making it ideal for cost-sensitive, display-rich industrial controllers where 120 MHz suffices.

FAQ
What is the maximum operating frequency of the MCF52274CLU120?
The MCF52274CLU120 operates at a maximum core clock frequency of 120 MHz, with peripheral and external bus clocks derived at half that rate (up to 60 MHz). This frequency is guaranteed across the full industrial temperature range (–40°C to +85°C) and is validated per Freescale's Rev. 8 datasheet. The MCF52274CLU120 achieves up to 114 Dhrystone 2.1 MIPS at this speed.
Does the MCF52274CLU120 support USB device and host modes?
Yes, the MCF52274CLU120 integrates a USB 2.0 On-The-Go (OTG) controller capable of both device and host operation. It supports full-speed (12 Mbps) communication and includes dedicated USB_DP and USB_DM pins with internal transceivers. The MCF52274CLU120 does not require an external USB PHY for basic OTG functionality.
What LCD interface capabilities does the MCF52274CLU120 provide?
The MCF52274CLU120 features a 12-bit parallel LCD controller supporting resolutions up to 800×600 pixels. It provides dedicated signals including LCD_D[17:0], LCD_LP/HSYNC, LCD_FLM/VSYNC, and LCD_LSCLK. Unlike the MCF52277, the MCF52274CLU120 does not support 18-bit color depth - this is explicitly specified in the family comparison table of the datasheet.
Is the MCF52274CLU120 pin-compatible with the MCF52277CVM160?
No, the MCF52274CLU120 is not pin-compatible with the MCF52277CVM160. The MCF52274CLU120 uses a 176-pin LQFP package, while the MCF52277CVM160 uses a 196-pin MAPBGA package. Their pinouts differ significantly - for example, LCD_D[17:16] appear on pins 9–8 in the LQFP but on pins C1–C2 in the MAPBGA. Migration requires full PCB redesign.
What power supply domains does the MCF52274CLU120 require?
The MCF52274CLU120 requires three primary supply domains: IVDD (1.5 V core), EVDD (3.3 V I/O), and SDVDD (1.8 V or 2.5 V SDRAM interface). Additional supplies include VDD_PLL (1.5 V), VDD_USB (3.3 V), VDD_RTC (1.5 V), and VDD_ADC (3.3 V). Proper sequencing - especially ensuring IVDD does not lead EVDD/SDVDD by more than 0.4 V - is mandatory per the hardware design guidelines.
