– Additions to M4K Group in the TXZ+™ Family Advanced Class boost code flash memory to 512KB/1MB –
KAWASAKI, Japan–(BUSINESS WIRE)–Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has added eight new products with 512KB/1MB flash memory capacity and four types of packages to the M4K Group of the TXZ+™ Family Advanced Class 32-bit microcontrollers equipped with Cortex®-M4 core with FPU.
Continuing advances in the functionality of motor applications supporting IoT is increasing demand for large program capacity and firmware over-the-air support.
The new products expand code flash memory capacity from the 256KB maximum of Toshiba’s current product to 512KB[1]/1MB[2], depending on the product, and RAM capacity from 24KB to 64KB. Other features, such as an Arm® Cortex®-M4 core running up to 160MHz, integrated code flash and 32KB data flash memory with 100K program/erase cycle endurance, have been maintained.
The microcontrollers also offer various interfaces and motor control options, such as advance-programmable motor driver (A-PMD), advanced encoder 32-bit (A-ENC32), advanced vector engine plus (A-VE+) and three units of high-speed, high-resolution 12-bit analog/digital converters. As a result, the M4K Group products contribute to wider application of IoT, and bring advanced functionality to AC motors, brushless DC motors and inverter controls.
The new products implement the 1MB code flash in two separate 512KB areas. This realizes firmware rotation with the memory swap method[3], allowing instructions to be read from one area while updated code is programmed into the other area in parallel.
Devices in the M4K Group have UART, TSPI and I2C integrated as general communications interfaces. Self-diagnosis functions incorporated in the devices for flash memory, RAM, ADC and Clock help customers to achieve IEC 60730 Class B functional safety certification.
Documentation, sample software with actual use examples, and driver software that controls the interfaces for each peripheral are available. Evaluation boards and development environments are provided in cooperation with Arm® global ecosystem partners.
Toshiba is planning to increase capacity of flash memory also for M4M Group with CAN interface.
Notes:
[1] Code flash memory capacity of TMPM4KxFDAxxG is 512KB with one area.
[2] Code flash memory capacity of TMPM4KxF10AxxG is 1MB, made up of two 512KB areas.
[3] TMPM4KxFDAxxG does not support this function.
