Toshiba M4K Motor Control Series Microcontrollers Have Flash Memory And Extended Memory

The Toshiba Arm Cortex-M4-based M4K range of microcontrollers includes eight new products and four packages with 512KB/1MB flash memory capacity. The M4K family is part of an advanced class of Toshiba’s TXZ+ family, which consists of five families of low-power, high-performance 32-bit microcontrollers.

The new microcontroller expands the flash code memory from the maximum 256 KB supported by current products to 512 KB/1 MB and the RAM from 24 KB to 64 KB. It has an Arm Cortex-M4 core, built-in code flash and 32KB data flash with 100,000 program/erase cycles.

This class of microcontrollers has a variety of motor control capabilities, such as three advanced programmable motor circuit modules, advanced 32-bit encoders, advanced redundant bus motors, and high-speed, high-precision 12-bit analog-to-digital converters. capable: there is. 3- Drives motors even in small (64 pin) applications.

The new product, which has 1MB of flash code, separates the memory into two separate 512KB regions, allowing for memory swapping and seamless wireless firmware updates, similar to Toshiba’s previous M3H group (2).
