NXP Semiconductors MCF52110CEP66

Overview

MCF52110CEP66 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller with 128 KB flash, 16 KB SRAM, and an 80 MHz core delivering 76 MIPS (Dhrystone 2.1). It integrates three UARTs, two I²C modules, QSPI, eight-channel 12-bit ADC with simultaneous sampling, four 32-bit DMA timers, and real-time clock - deployed in industrial motor control and embedded HMI systems.

For engineers reviewing the MCF52110CEP66 datasheet, MCF52110CEP66 pinout, MCF52110CEP66 application, or MCF52110CEP66 equivalent, key selection criteria include its 64-pin LQFP package, 66 MHz maximum system clock (confirmed for this variant), ColdFire V2 ISA_A+ instruction set support, MAC unit for signal processing, and dual watchdog architecture with independent backup timer.

Technical Context

The MCF52110CEP66 implements the ColdFire Version 2 core with static operation, 32-bit address/data paths, and ISA_A+ extensions including user stack pointer and bit-processing instructions. Its MAC unit supports 16×16→32 and 32×32→32 operations with a 32-bit accumulator, enabling efficient DSP tasks without external coprocessors.

On-chip peripherals are tightly coupled via the local bus: the 128 KB flash uses interleaved 2-1-1-1 access timing, the 16 KB dual-ported SRAM allows concurrent CPU/DMA access, and the ADC features two independent sample-and-hold circuits for true simultaneous dual-channel acquisition - critical for motor phase current sensing.

FAQ

What is the maximum operating frequency of the MCF52110CEP66?

The MCF52110CEP66 is rated for a maximum system clock frequency of 66 MHz, as specified in Table 1 (Family Configurations) of the Freescale MCF52110 Rev. 1 datasheet. This variant operates at 66 MHz - distinct from the 80 MHz MCF52110CAG80 - and delivers 76 MIPS (Dhrystone 2.1) when running from internal flash memory. The PLL supports multiplication of lower-frequency crystals to achieve this clock rate.

Does the MCF52110CEP66 support simultaneous sampling on its ADC?

Yes, the MCF52110CEP66 supports true simultaneous sampling on two ADC channels using its dual sample-and-hold circuitry, as documented in Section 1.2.10 of the datasheet. This capability enables synchronized acquisition of motor phase currents or differential sensor pairs without time skew, which is critical for accurate field-oriented control algorithms executed on the ColdFire V2 core.

Which package type does the MCF52110CEP66 use?

The MCF52110CEP66 uses the 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), as indicated by the "E" in the part number suffix and confirmed in Section 3.1 (Mechanical Outline Drawings) of the MCF52110 Rev. 1 datasheet. This package supports all core peripherals, though UART2 shares pins with GPIO and the full JTAG debug interface is reduced compared to the 100-pin variant.

How many UART interfaces does the MCF52110CEP66 include?

The MCF52110CEP66 integrates three UART modules (UART0, UART1, UART2), as stated in the feature summary and Table 1. On the 64-pin LQFP package, UART2 signals are multiplexed with general-purpose I/O pins per Section 1.2.7, requiring careful pin assignment in PCB layout. All three UARTs support DMA, FIFO buffering, and modem control lines (RTS/CTS on UART0 and UART1).

What watchdog timer architecture does the MCF52110CEP66 implement?

The MCF52110CEP66 implements a dual watchdog system: a 32-bit software watchdog timer (SWT) and an independent 16-bit backup watchdog timer (BWT), both detailed in Sections 1.2.16 and 1.2.17. The BWT can be clocked by either the on-chip 8 MHz relaxation oscillator or the system clock, ensuring continued supervision even if the main clock fails - a key reliability feature for industrial control firmware.
