Toshiba has introduced eight new entries in its M4K group of TXZ+ 32-bit microcontrollers, focusing on motor management tasks with elevated flash reminiscence — as much as 1MB, model-dependent, from the present most of 256kB.

Constructing on the corporate’s current TXZ+ M4K components, which embody a programmable motor driver for synchronous management of as much as three motors, the brand new components embody a single Arm Cortex-M4F microcontroller core operating at as much as 160MHz and a alternative of 512kB or 1MB of code flash reminiscence alongside 32kB of knowledge flash — a giant enhance from the present fashions’ 256kB code flash higher restrict.

The components additionally embody 64kB of static RAM (SRAM), a 32-bit “superior encoder”, a vector acceleration engine dubbed the A-VE+, and three high-speed high-resolution 12-bit analog to digital converters (ADCs). There are three or 4 UART buses, model-depending, two I2C/EI2C buses, two TSPI buses, three operational amplifiers, a voltage detection circuit, 30- or 32-channel direct reminiscence entry (DMA), and 51- or 87-pin enter/output connectivity with 20 or 32 exterior interrupt pins relying on mannequin.

The 1MB variants include an added characteristic for secure over-the-air updates, too: the flash reminiscence may be break up into two 512kB areas the place one is learn whereas new directions are programmed into the opposite in parallel, one thing not potential with the 512kB and smaller components. All fashions embody flash longevity rated as much as 100,000 erase-rewrite cycles.

The improve to the M4K line has not, nonetheless, been carried by to the M4M vary — related microcontrollers additionally focusing on motor management functions however that provide a CAN bus controller. That, Toshiba guarantees, will probably be addressed in a future M4M line replace — although, on the time of writing, no launch date had been offered.

Extra data on the brand new components is accessible on the Toshiba web site; pricing is accessible on utility.
