Toshiba Introduces ARM® Cortex®-M3 Microcontrollers “TXZ+TM Family Advanced Class” with 1MB Code Flash Memory Supporting Firmware Updates without Interrupting Microcontroller Operation
Toshiba: ARM(R) Cortex(R)-M3 Microcontrollers “TXZ+(TM) Family Advanced Class” (Graphic: Business Wire)
In the new products, the 1MB[1] code flash is implemented with two separate areas of 512KB each. This implementation allows instructions to be read from one area, while the updated code is programmed into the other area in parallel. Finally, the firmware rotation function is realized by the area swap function[3].
The M3H group products are equipped with UART, TSPI, I2C interface, 2-unit DMAC and an LCD Display Controller[4] to meet the requirements from a variety of consumer or industrial applications. To support various kinds of sensing, the new products have maximum 21 channels of 12-bit high-speed, high-precision analog/digital converter (ADC), that are selectable from two sample hold time for each analog input pin. In addition, they are suitable for controlling AC motors and brushless DC motors in combination with an advanced Programmable Motor Control Circuit and Advanced Encoder Input Circuit that can operate synchronously with the high-speed, high-precision 12-bit analog/digital converter.
The 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 usage 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.
