NXP Semiconductors MMC2107CFCAG33

Overview

MMC2107CFCAG33 from Freescale Semiconductor (now NXP) is a 32-bit M•CORE-based microcontroller unit with integrated 512 KB FLASH, 32 KB SRAM, PLL clock synthesis, dual SCI, SPI, QADC, EBI, and JTAG/OnCE debug support. It operates at up to 66 MHz and targets industrial control, automotive body electronics, and embedded instrumentation.

For engineers reviewing the MMC2107CFCAG33 datasheet, MMC2107CFCAG33 pinout, MMC2107CFCAG33 application, or MMC2107CFCAG33 equivalent, key selection criteria include its HCMOS-compatible 144-pin LQFP package, 3.3 V core/I/O supply, PLL lock detection, external bus interface timing, and OnCE real-time debugging capability.

Technical Context

The MMC2107CFCAG33 implements the M•CORE M210 CPU core - a 32-bit RISC architecture with 16 × 32-bit general-purpose registers, 16-bit fixed-length instruction encoding, and hardware multiply/divide. It integrates a programmable interrupt controller supporting 64 vectored interrupts with priority levels and fast/normal modes.

Its clock system includes an on-chip PLL with selectable multiplication factors (×1 to ×12), loss-of-clock and loss-of-lock detection with automatic reset assertion, and four low-power modes (Wait, Doze, Stop, and Disabled). The external bus interface supports 32-bit data width, 24-bit addressing, and configurable wait-state generation for asynchronous peripherals.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the MMC2107CFCAG33?

The MMC2107CFCAG33 achieves a maximum system clock frequency of 66 MHz using its on-chip PLL with external crystal or clock input. This frequency is sustained under specified temperature and voltage conditions (3.3 V ±0.3 V, –40°C to +105°C), and enables deterministic execution of real-time control tasks such as motor commutation and sensor sampling within tight timing windows. The MMC2107CFCAG33 datasheet specifies this as the absolute maximum rated frequency for continuous operation.

Does the MMC2107CFCAG33 support external memory expansion?

Yes, the MMC2107CFCAG33 includes a full External Bus Interface (EBI) supporting 32-bit data width, 24-bit address space, programmable wait states, and burst transfers. It interfaces directly with asynchronous SRAM, NOR flash, and peripheral ASICs/FPGAs without glue logic. The MMC2107CFCAG33 EBI signals - including D[31:0], A[22:0], CS[3:0], OE, and R/W - are fully routed on the 144-pin LQFP package, enabling seamless integration into memory-mapped system architectures.

What debug capabilities does the MMC2107CFCAG33 provide?

The MMC2107CFCAG33 integrates the OnCE (On-Chip Emulation) module, which delivers real-time, non-intrusive debugging via JTAG pins (TRST, TCLK, TMS, TDI, TDO). It supports hardware breakpoints, data watchpoints, register visibility, and instruction trace without halting CPU execution. Unlike conventional ICE, OnCE operates concurrently with application code - a capability confirmed in Section 21 of the MMC2107CFCAG33 technical data - making it ideal for debugging time-critical control loops.

How does the MMC2107CFCAG33 handle power failure or clock faults?

The MMC2107CFCAG33 incorporates dual fault-detection circuits: loss-of-clock (LOC) and loss-of-lock (LOL). LOC monitors EXTAL/XTAL presence and asserts reset within 2 µs if the reference clock disappears; LOL detects PLL unlock and triggers reset within the same timeframe. Both features are hardware-implemented and independent of software polling. These mechanisms ensure fail-safe behavior in the MMC2107CFCAG33, preventing erratic operation during oscillator or PLL failures - a requirement verified in Section 10.8.3 and 10.8.4 of its technical data.

What is the role of the VPP pin on the MMC2107CFCAG33?

The VPP pin on the MMC2107CFCAG33 supplies +12 V exclusively during FLASH memory erase and program operations. It is not required during normal execution, reset, or standby modes. This high-voltage rail enables Fowler-Nordheim tunneling for reliable charge injection into the floating gate of the CMFR FLASH array. The MMC2107CFCAG33 datasheet specifies that VPP must be applied only when executing FLASH command sequences - incorrect application risks permanent damage to the FLASH controller or memory cells.
