NXP Semiconductors MCF52110CAE80

Overview

MCF52110CAE80 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller operating at up to 80 MHz, featuring 128 KB flash, 16 KB SRAM, three UARTs, two I²C interfaces, QSPI, eight-channel 12-bit ADC with simultaneous sampling, and four 32-bit DMA-capable timers - deployed in industrial motor control and embedded automation systems.

For engineers reviewing the MCF52110CAE80 datasheet, MCF52110CAE80 pinout, MCF52110CAE80 application, or MCF52110CAE80 equivalent, key selection considerations include its 80 MHz ColdFire V2 core with MAC unit, dual watchdog timers (software + backup), RTC with 32 kHz crystal support, and package-specific debug interface availability (full JTAG/trace only on 100-pin LQFP).

Technical Context

The MCF52110CAE80 implements the ColdFire ISA_A+ instruction set with static 32-bit RISC architecture, including a hardware multiply-accumulate (MAC) unit supporting 16×16→32 and 32×32→32 operations. Its clock system integrates an 8 MHz on-chip relaxation oscillator, PLL with programmable pre-divider, and selectable clock sources (crystal, OCO, or external).

On-chip peripherals include a four-channel DMA controller with burst transfer support, a fast 12-bit ADC with dual sample-and-hold for simultaneous two-channel acquisition, and a programmable interrupt controller handling 57 sources with individually configurable priority and vectoring - all tightly coupled to the CPU via high-speed local bus.

FAQ

What is the maximum operating frequency of the MCF52110CAE80?

The MCF52110CAE80 operates at a maximum core frequency of 80 MHz using its integrated Phase-Locked Loop (PLL). This frequency is achieved with an external crystal or the on-chip 8 MHz relaxation oscillator as the reference source. The device delivers 76 MIPS (Dhrystone 2.1) at this speed when executing from internal flash memory. The MCF52110CAE80 also supports lower-frequency modes for power optimization, including a 2ⁿ divider for ultra-low-power operation.

Does the MCF52110CAE80 support simultaneous sampling on its ADC channels?

Yes, the MCF52110CAE80 features an eight-channel 12-bit ADC with two independent sample-and-hold (S/H) circuits, enabling true simultaneous sampling of two analog inputs. This capability is essential for applications like motor phase current measurement where timing alignment between channels is critical. The MCF52110CAE80 supports both sequential and simultaneous conversion modes, and unused ADC inputs can be reconfigured as general-purpose I/O pins.

What debug interfaces are supported by the MCF52110CAE80?

The MCF52110CAE80 supports Background Debug Mode (BDM) and IEEE 1149.1 JTAG interfaces. Full real-time trace and six hardware breakpoints are available only on the 100-pin LQFP package variant. Smaller packages (LQFP-64, QFN-64, MAPBGA-81) retain the dedicated debug serial channel (DSI/DSO/DSCLK) and ALLPST signal for basic halt/resume control and status monitoring. The MCF52110CAE80 implements ColdFire Debug Architecture revision B+.

How many UART interfaces does the MCF52110CAE80 include, and what are their key capabilities?

The MCF52110CAE80 integrates three full-duplex UART modules. Each supports 5–8 bit data formats, programmable parity, up to two stop bits, and hardware flow control (RTS/CTS on UART0 and UART1). All three UARTs provide FIFO buffering, DMA request generation, and maskable interrupts. On LQFP-64 and QFN-64 packages, UART2 is multiplexed with GPIO functions, while it remains fully dedicated on 100-pin LQFP and MAPBGA-81 variants. The MCF52110CAE80 UARTs are clocked directly from the system bus, eliminating need for external timing sources.

What is the purpose of the dual watchdog timers in the MCF52110CAE80?

The MCF52110CAE80 includes two independent watchdog timers: a 32-bit software watchdog timer (SWT) and a 16-bit backup watchdog timer (BWT). The SWT resets the processor core upon underflow unless refreshed by firmware; the BWT operates from a separate clock source (on-chip relaxation oscillator or system clock) and provides fail-safe recovery if the main clock fails. This dual-timer architecture ensures robust fault detection in safety-critical applications such as industrial control, where the MCF52110CAE80 must maintain operational integrity despite clock or software faults.
