NXP Semiconductors MMC2114CFCPU33

Overview

MMC2114CFCPU33 from Freescale Semiconductor is a 32-bit M•CORE microcontroller featuring the M210 RISC CPU core, 256 KB on-chip FLASH memory, 32 KB SRAM, and integrated peripherals including dual SCI, SPI, QADC, two timers, PLL, LVD, and 43-source interrupt controller. It operates at 33 MHz with 31 Dhrystone 2.1 MIPS performance and targets embedded control in industrial automation and automotive subsystems.

For engineers reviewing the MMC2114CFCPU33 datasheet, MMC2114CFCPU33 pinout, MMC2114CFCPU33 application, or MMC2114CFCPU33 equivalent, key selection criteria include its 100-pin LQFP package, 5V-tolerant digital I/O, single-supply FLASH programming, and OnCE/JTAG debug support for in-situ development and system-level board testing.

Technical Context

The MMC2114CFCPU33 implements a 4-stage pipelined 32-bit RISC architecture with fixed 16-bit instruction encoding, enabling single-cycle execution for most instructions and efficient code density. Its M210 CPU supports byte/half-word/word memory access, vectored interrupts with 32 priority levels, and full static design for low-power operation.

On-chip subsystems include a queued 10-bit ADC with 8 analog inputs and 64-entry dual-command queues, an external bus interface supporting 32 MB address space with 23-bit addressing, and dual periodic interval timers with 16 selectable prescalers - all synchronized to the PLL-derived system clock operating at 33 MHz.

FAQ

What is the maximum operating frequency of the MMC2114CFCPU33?

The MMC2114CFCPU33 operates at a maximum system clock frequency of 33 MHz, delivering 31 Dhrystone 2.1 MIPS performance. This frequency is derived from the internal PLL locked to an external 2–10 MHz crystal oscillator. The device maintains full functionality and timing compliance across its specified industrial temperature range when operated at this rated speed. All peripherals - including the QADC, timers, and serial interfaces - are synchronized to this clock domain.

Does the MMC2114CFCPU33 support in-circuit debugging?

Yes, the MMC2114CFCPU33 integrates the OnCE (On-Chip Emulation) debug module compliant with IEEE 1149.1 JTAG, enabling non-intrusive real-time debugging, breakpoint setting, register inspection, and memory access without halting CPU execution. It also supports Motorola's Enhanced Background Debug Interface (EBDI) via the 14-pin header. This capability is fully implemented in the MMC2114CFCPU33 and does not require external debug probes beyond standard JTAG adapters.

What are the memory configuration options for the MMC2114CFCPU33?

MMC2114CFCPU33 contains 256 KB of on-chip FLASH memory and 32 KB of SRAM, both accessible in single-cycle mode for byte/half-word/word operations. FLASH supports banked execution - allowing code execution from one bank while programming the other - and includes a three-tier security scheme to protect intellectual property. SRAM features standby power supply support for data retention during low-power modes, and both memories are mapped into the unified 32-bit address space managed by the M210 CPU.

Is the MMC2114CFCPU33 pin-compatible with other members of the MMC211x family?

MMC2114CFCPU33 is pin-compatible with MMC2113CFCPU33 in the same 100-pin LQFP package, sharing identical pin functions, electrical characteristics, and footprint. However, it is not pin-compatible with MMC2114CFCPV33 (144-pin LQFP) or MMC2114FCVF33 (196-ball MAPBGA), which offer expanded I/O and external bus signals. Board designs using MMC2113CFCPU33 can be upgraded to MMC2114CFCPU33 without layout changes, provided firmware accommodates increased memory size.

What power supply requirements does the MMC2114CFCPU33 have?

The MMC2114CFCPU33 requires a nominal 3.3 V ±0.3 V supply for core and I/O operation, with separate analog (VDDA/VSSA) and digital (VDD/VSS) power domains. It incorporates an integrated low-voltage detector (LVD) with user-selectable threshold and response (interrupt or reset), and supports multiple low-power modes including stop and wait states. The device draws approximately 60 mA at 33 MHz with all peripherals active, scaling dynamically with clock gating and peripheral enable controls - enabling energy-efficient operation in battery-backed applications.
