NXP Semiconductors MMC2107CFCPU33

Overview

MMC2107CFCPU33 from Freescale Semiconductor (now NXP) is a 32-bit HCMOS microcontroller unit based on the M•CORE M210 CPU core, featuring 32 KB on-chip FLASH, 4 KB SRAM, dual SCI, SPI, QADC, EPORT, and PLL clock generation. It operates at up to 33 MHz and targets embedded control in industrial automation and automotive subsystems.

For engineers reviewing the MMC2107CFCPU33 datasheet, MMC2107CFCPU33 pinout, MMC2107CFCPU33 application, or MMC2107CFCPU33 equivalent, key selection factors include its 33 MHz CPU frequency, 100-pin PQFP package, integrated PLL with loss-of-lock detection, dual serial interfaces, and on-chip FLASH/EEPROM emulation capability.

Technical Context

The MMC2107CFCPU33 implements the M•CORE M210 32-bit RISC CPU with Harvard architecture, supporting byte/word/dword addressing and 16/32-bit instruction encoding. Its clock module integrates a PLL with programmable multiplication factor (MFD), VCO, charge pump, and lock-detection logic for stable system timing.

It includes a dedicated Chip Configuration Module (CCM) for boot mode selection (single-chip/master/emulation), reset configuration, and output pad strength control. Memory mapping supports unified 32-bit address space with configurable chip selects, external bus interface (EBI), and memory-mapped peripheral registers across 22-bit address range.

FAQ

What is the maximum operating frequency of the MMC2107CFCPU33?

The MMC2107CFCPU33 is rated for a maximum CPU frequency of 33 MHz. This speed is achieved using the on-chip PLL with an external crystal (typically 4–8 MHz) or CMOS clock source. The PLL's multiplication factor and stability are validated across the full industrial temperature range (–40°C to +85°C), and the device's timing specifications assume operation at this rated frequency. Exceeding 33 MHz violates the manufacturer's electrical specifications.

Does the MMC2107CFCPU33 support in-system programming of its on-chip FLASH memory?

Yes, the MMC2107CFCPU33 supports in-system programming (ISP) of its 32 KB on-chip FLASH memory via the CMFR module. Programming requires VPP = 12 V applied to the dedicated pin and uses a controlled sequence of command writes to FLASH control registers. The process is fully documented in Section 9.8.4 of the Rev. 2.0 Technical Data, including margin read verification and pulse-width modulation for reliability.

What peripheral interfaces are integrated into the MMC2107CFCPU33?

The MMC2107CFCPU33 integrates dual Serial Communications Interfaces (SCI1 and SCI2), one Serial Peripheral Interface (SPI), a Queued Analog-to-Digital Converter (QADC) with eight analog inputs, two Programmable Interrupt Timers (PIT1/PIT2), two Timer Modules (TIM1/TIM2), Edge Port (EPORT), and an External Bus Interface (EBI). All are memory-mapped and accessible via the 32-bit address/data bus.

Is the MMC2107CFCPU33 pin-compatible with other members of the MMC2107 family?

Yes, the MMC2107CFCPU33 is pin-compatible with other speed-grade variants in the MMC2107 family, including MMC2107CFCPU40 and MMC2107CFCPU25, all packaged in the same 100-pin PQFP. Pin assignments, signal names, and electrical characteristics are identical across these variants; only the maximum rated frequency and associated AC timing parameters differ.

What debug and emulation features does the MMC2107CFCPU33 provide?

The MMC2107CFCPU33 includes JTAG Test Access Port (TAP) and OnCE (On-Chip Emulation) support per Section 21 of the Technical Data. It supports boundary-scan testing, real-time debugging, breakpoint insertion, and register visibility via dedicated TDI/TDO/TMS/TRST/TCLK pins. OnCE enables non-intrusive program flow observation and memory access without halting CPU execution.
