Product details

It runs at 48 MHz with 128 KB of Flash program memory and 16 KB of RAM, packaged in a 121-ball MAPBGA (8x8 mm) for dense PCB layouts.

Memory and peripheral budget for a BGA-footprint MCU

128 KB Flash and 16 KB RAM on a 48 MHz Cortex-M0+ core is a balanced pairing for mid-complexity firmware — enough for a USB CDC stack plus a Modbus RTU slave, but the 16 KB RAM imposes a ceiling on data buffering. If your application streams multiple ADC channels over USB, watch the heap allocation. The 84 I/O count in a 121-ball BGA means roughly 37 balls are power or ground — expect a 4-layer PCB minimum.

Frequently asked questions

What are the key specifications of MKL46Z128VMC4?

The MKL46Z128VMC4 is a 32-bit ARM Cortex-M0+ MCU running at 48 MHz with 128 KB Flash and 16 KB RAM. It has 84 I/O, USB OTG, LINbus, SPI, I²C, and UART interfaces, plus 16-bit ADC and 12-bit DAC converters. The supply range is 1.71 V to 3.6 V and it operates from -40°C to 105°C in a 121-ball MAPBGA package.

Does MKL46Z128VMC4 have a pin-compatible alternative?

No official pin-compatible replacement or second-source alternate is listed in the available documentation. For a drop-in alternative, cross-reference other Kinetis KL4 series devices in the same 121-MAPBGA package — density and peripheral sets vary by order code.

What is the operating temperature range of MKL46Z128VMC4?

The operating temperature range is -40°C to 105°C, making it suitable for industrial and automotive auxiliary applications where ambient temperatures exceed standard commercial limits.
