Toshiba: ARM(R) Cortex(R)-M3 Microcontrollers "TXZ+(TM) Family Advanced Class" (Graphic: Business Wire)
In recent years, the need for larger program capacity and support for FOTA (Firmware update Over The Air) has been increasing. This is driven by the penetration of digital technology, especially in the IoT (Internet of Things) area, and by the increasingly advanced functionality required in various devices. The new products M3H group (2) has expanded the code flash memory capacity from 512KB (partially 256KB or 384KB) of the Toshiba’s existing products M3H group (1) to 1MB [1], and the RAM capacity from 66KB [2] of the Toshiba’s existing products M3H group (1) to 130KB [2]. Other features, such as an ARM ® Cortex ® -M3 core running up to 120MHz, integrated code flash, and 32KB data flash memory with 100K program/erase cycle endurance have been maintained. These microcontrollers also offer various interface and motor control options, such as UART, I 2 C interface, Advanced Encoder Input Circuit, and Advanced Programmable Motor Control Circuit. Toshiba’s lineup of Microcontrollers in the M3H group contribute to IoT and advanced functionality in a wide range of applications including motors, home appliances, and industrial equipment.
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, I 2 C 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.
