Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MK51DX128CLH7 | Same 72 MHz Cortex-M4 core, 128 KB flash, 32 KB SRAM, but in 64-pin LQFP package with 31 GPIO and no segment LCD controller. | Lacks integrated segment LCD driver; suitable for non-display applications requiring smaller footprint and lower pin count. | Select when display interface is unnecessary and PCB space constraints favor 64-pin LQFP over 121-pin MAPBGA. |
| MK50DN256CLK7 | 72 MHz Cortex-M4 with 256 KB flash, 64 KB SRAM, same peripheral set, but uses standard flash-only (no FlexNVM/FlexRAM) memory architecture. | No FlexMemory configurability; EEPROM must be emulated in main flash or added externally. | Select when larger code space is required and EEPROM-like wear-leveling is handled in software or external storage. |
Compared with MK51DX128CLH7 and MK50DN256CLK7, the MK50DX128CMC7 uniquely combines FlexMemory-based EEPROM backup, USB DCD, and 121-pin MAPBGA packaging-making it optimal for space-constrained, battery-powered HMI systems requiring reliable nonvolatile parameter storage and smart charging awareness.

FAQ
What is the maximum operating frequency and core type of the MK50DX128CMC7?
The MK50DX128CMC7 features an ARM Cortex-M4 core with DSP extensions, rated for a maximum CPU frequency of 72 MHz. It does not include a floating-point unit (FPU). This configuration delivers 1.25 DMIPS/MHz performance and supports real-time signal processing tasks such as motor control, sensor fusion, and audio preprocessing-all within the MK50DX128CMC7's power and thermal envelope.
Does the MK50DX128CMC7 support USB Device Charger Detect (DCD)?
Yes, the MK50DX128CMC7 includes hardware-level USB Device Charger Detect (DCD) compliant with USB Battery Charging Specification v1.2. This feature enables the MK50DX128CMC7 to autonomously identify SDP, CDP, and DCP chargers without external components-critical for battery-powered devices requiring intelligent charging behavior and firmware update readiness upon connection.
How is FlexMemory implemented in the MK50DX128CMC7?
The MK50DX128CMC7 includes 32 KB of FlexNVM and allocates 2 KB of FlexRAM. Users can configure FlexNVM as additional program/data flash or EEPROM backup, while FlexRAM defines the EEPROM array size (here, 2 KB). This enables true byte-write/erase operations with >10 million endurance cycles-fully supported by the MK50DX128CMC7's runtime drivers and requiring no external EEPROM IC or software emulation layer.
What analog peripherals are integrated into the MK50DX128CMC7?
The MK50DX128CMC7 integrates two independent 16-bit SAR ADCs (ADC0: 19 SE + 3 DP channels; ADC1: 16 SE + 3 DP), one 12-bit DAC, three high-speed analog comparators, one programmable gain amplifier (PGA), one operational amplifier (OPAMP), one transimpedance amplifier (TRIAMP), and a programmable voltage reference (VREF). These peripherals are fully accessible in the MK50DX128CMC7's 121-pin MAPBGA package and support simultaneous sampling and hardware averaging.
Is the MK50DX128CMC7 pin-compatible with other K50 family members?
Yes-the MK50DX128CMC7 shares the 121-pin MAPBGA (MC) package footprint with other K50 devices like MK50DX256ZCMC10 and MK50DN512ZCMC10. All MC-package K50 parts are pin-for-pin compatible per Freescale's K50 Family Product Brief (Rev. 8, Table 2), enabling scalable migration within the same package while preserving PCB layout and interconnect integrity for the MK50DX128CMC7 and its higher-memory variants.
