NXP Semiconductors MMC2107CFCAF33

Overview

MMC2107CFCAF33 from Freescale Semiconductor (now NXP) is a 32-bit HCMOS microcontroller unit based on the M•CORE M210 CPU core, featuring 128 KB on-chip FLASH, 8 KB SRAM, dual SCI, SPI, QADC, EBI, and PLL clock synthesis. It operates at up to 66 MHz and targets industrial control and embedded communication systems.

For engineers reviewing the MMC2107CFCAF33 datasheet, MMC2107CFCAF33 pinout, MMC2107CFCAF33 application, or MMC2107CFCAF33 equivalent, key selection considerations include its 144-pin LQFP package, 3.3 V supply, integrated FLASH programming support (VPP), and compatibility with Motorola/Freescale M•CORE development tools and toolchains.

Technical Context

The MMC2107CFCAF33 implements the M•CORE M210 32-bit RISC CPU with Harvard architecture, supporting 16-/32-bit instruction sets and 32-bit data paths. Its clock module integrates a PLL with programmable multiplication factor (MFD), loss-of-lock detection, and multiple low-power modes (Wait, Doze, Stop).

It includes a 16-channel Queued Analog-to-Digital Converter (QADC) with 10-bit resolution, two independent Serial Communications Interfaces (SCI1/SCI2) with LIN-capable framing, and an External Bus Interface (EBI) supporting 32-bit data and 23-bit address buses for external memory expansion.

Key Specifications

Pinout & Package

The MMC2107CFCAF33 is housed in a 144-pin Low-Profile Quad Flat Package (LQFP) with 0.5 mm lead pitch and 20 mm × 20 mm body size. Pin assignments follow Freescale's standard M•CORE pinout layout for signal integrity and thermal management in high-density PCBs.

The MMC2107CFCAF33 belongs to the M•CORE M210 product line, designed specifically for cost-effective, real-time embedded control applications requiring integrated analog capture, serial networking, and expandable memory - especially where legacy code base and toolchain continuity matter.

FAQ

What is the maximum operating frequency of the MMC2107CFCAF33?

The MMC2107CFCAF33 supports a maximum system clock frequency of 66 MHz, achieved via its integrated PLL synthesizer. This frequency is derived from an external crystal (1–8 MHz) or oscillator input applied to EXTAL/XTAL pins. The PLL's multiplication factor is programmable through the Synthesizer Control Register, and lock status is monitored via the Synthesizer Status Register. Operation above 66 MHz is not supported and may cause functional failure.

Does the MMC2107CFCAF33 require an external 12 V supply for FLASH programming?

Yes, the MMC2107CFCAF33 requires a 12 V supply on the VPP pin during FLASH erase and program operations. This voltage is only needed during non-volatile memory updates and is not present during normal execution. The device includes internal charge pumps and safety logic to prevent accidental programming; VPP must be actively driven to 12 V and sequenced correctly per the CMFR module timing requirements in Section 9 of the datasheet.

How many serial communication interfaces does the MMC2107CFCAF33 include, and what protocols do they support?

The MMC2107CFCAF33 includes two independent Serial Communications Interface (SCI) modules - SCI1 and SCI2 - each supporting asynchronous UART operation with LIN 1.3 and LIN 2.x frame formats. Both modules feature break detection, wakeup capability, and programmable baud rates. Neither supports synchronous protocols like SPI or I²C; those functions are handled separately by the dedicated SPI module and EBI-controlled peripherals.

What debug interface does the MMC2107CFCAF33 provide, and is JTAG sufficient for full development?

MMC2107CFCAF33 provides IEEE 1149.1-compliant JTAG test access port plus Freescale's OnCE (On-Chip Emulation) real-time debug interface. JTAG alone supports boundary-scan and basic flash programming, but full development - including real-time breakpoints, register visibility, and non-intrusive stepping - requires OnCE-enabled tools such as P&E Multilink or older Freescale D-Bug12 adapters. The TRST, TCK, TMS, TDI, and TDO pins serve both standards.

Can the MMC2107CFCAF33 operate in low-power modes, and which peripherals remain active during Stop mode?

Yes, the MMC2107CFCAF33 supports Wait, Doze, and Stop low-power modes controlled via the Chip Configuration Module (CCM). In Stop mode, the CPU, PLL, and most clocks halt; only the RTC (if enabled), certain wake-up sources (e.g., external interrupt pins, SCI break detect), and the reset controller remain active. FLASH, SRAM, and peripheral registers retain state. Wake-up exits Stop mode and restores full operation after clock stabilization and reset release.
