NXP Semiconductors MMC2114CFCAF33

Overview

MMC2114CFCAF33 from Freescale Semiconductor is a 32-bit M•CORE microcontroller featuring a pipelined RISC CPU, 256 KB on-chip FLASH, 32 KB SRAM, dual SCI interfaces, SPI, QADC with 8 channels and 10-bit resolution, PLL clock generation, and integrated low-voltage detection. It operates at 33 MHz and delivers 31 Dhrystone 2.1 MIPS in embedded control applications requiring compact code footprint and low-power operation.

For engineers reviewing the MMC2114CFCAF33 datasheet, MMC2114CFCAF33 pinout, MMC2114CFCAF33 application, or MMC2114CFCAF33 equivalent, key selection criteria include its 144-pin LQFP package, 5V-tolerant digital I/O, single-supply FLASH programming, and OnCE/JTAG debug support for real-time firmware development and system-level board validation.

Technical Context

The MMC2114CFCAF33 implements the M•CORE M210 CPU core with a 4-stage pipeline, fixed 16-bit instruction encoding, and full static design enabling zero-wait-state operation at 33 MHz. Its memory subsystem includes 256 KB of Second Generation FLASH (SGFM) supporting concurrent execute-and-program operations across two banks, and 32 KB of single-cycle SRAM with standby power support.

Peripheral integration includes a 43-source interrupt controller with 32 priority levels, two 16-bit timers with input capture/output compare, two periodic interval timers, watchdog timer, and a queued analog-to-digital converter with dual 64-entry command queues triggered by external events or timers - all accessible via a coherent 32-bit IPBus interconnect.

FAQ

What is the maximum operating frequency of the MMC2114CFCAF33?

The MMC2114CFCAF33 operates at a maximum frequency of 33 MHz, delivering 31 Dhrystone 2.1 MIPS performance. This frequency is achieved using the internal PLL driven by an external 2–10 MHz crystal connected to EXTAL/XTAL pins. The device supports both PLL-enabled and crystal-bypass clock modes, and its fully static design allows operation down to DC.

Does the MMC2114CFCAF33 support in-system programming of its FLASH memory?

Yes, the MMC2114CFCAF33 supports in-system programming using its Second Generation FLASH (SGFM) technology. It requires no external programming voltage (single 3.3 V supply), features automated program/erase with interrupt support, and allows concurrent execution from one FLASH bank while programming the other - a capability confirmed for the MMC2114 variant in the product brief.

What debug interface does the MMC2114CFCAF33 provide?

The MMC2114CFCAF33 integrates the OnCE (On-Chip Emulation) interface alongside IEEE 1149.1 JTAG (TMS, TDI, TDO, TCK, TRST). OnCE enables non-intrusive real-time debugging, including breakpoints, watchpoints, and register inspection without halting CPU execution - essential for validating time-critical firmware on the MMC2114CFCAF33.

Is the MMC2114CFCAF33 pin-compatible with earlier M•CORE devices like the MMC2107?

No, the MMC2114CFCAF33 is not pin-compatible with the MMC2107. While both use LQFP packages, the MMC2114CFCAF33 is specified in a 144-pin LQFP (CFCPV33 suffix), whereas MMC2107 variants use 100-pin or 144-pin LQFP with different pin assignments and peripheral mappings - confirmed by distinct package diagrams and feature enhancements documented in the MMC2114 product brief.

What analog capabilities does the MMC2114CFCAF33 offer?

The MMC2114CFCAF33 includes a Queued Analog-to-Digital Converter (QADC) with eight 10-bit input channels, ±2 LSB accuracy, and minimum 7 µs conversion time. It supports two independent 64-entry command queues, automated triggering via timers or external events, and three output data formats - enabling deterministic, low-CPU-overhead acquisition critical for control loops on the MMC2114CFCAF33.
