This requires motor-control microcontrollers that add functions for improved development efficiency and system reliability alongside high-precision control.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Please try againToshiba’s new products are compact microcontrollers specifically designed for single-motor control applications that integrate dedicated motor-control hardware[1], security functions, and functional safety measures on a single chip. By offloading motor-control processing to dedicated hardware, they reduce the CPU load, enabling highly efficient and precise motor control.The microcontrollers are built around an Arm® Cortex®‑M4 core with FPU and operate at frequencies up to 80MHz. They support a supply voltage range of 2.7V to 5.5V, delivering compatibility with existing 3V‑ and 5V‑based systems while bringing high design flexibility to new designs. They are available in four types of small package with 44 to 64 pins and two different memory configurations, allowing selection according to application requirements. Integration of a high‑speed oscillator with ±1% accuracy[2] and an overcurrent detection comparator for emergency motor shutdown reduces external components and helps minimize board area. In addition, a low‑power STOP2 mode supports battery‑powered applications.The 256KB products[3] adopt dual‑bank flash memory with two 128KB blocks, allowing one program to be executed while the other area is rewritten. This secures program updates without stopping system operation and facilitates implementation of firmware over-the-air updates. The 128KB products[4] incorporate 64KB of data flash memory to support storage of log data and management of configuration information.For security, the microcontrollers integrate chip protection (CPRO), secure access memory (SAM), and non‑rewritable flash protection (NRFP). These functions help prevent unauthorized access, control memory access, and protect critical areas, thereby improving system reliability across a wide range of applications, including IoT devices.The microcontrollers also integrate general‑purpose communications interfaces, such as universal asynchronous receiver/transmitter (UART), a serial peripheral interface (SPI), an inter‑integrated circuit[5], and a serial memory interface (SMIF) for external memory connectivity. Functional safety measures include abnormality detection covering flash memory, RAM, analog‑to‑digital converters and clock systems. Toshiba also provides certified software compliant with UL 60730 Class B, a functional safety standard for household appliances, helping customers streamline their certification processes.Toshiba supports evaluation and development with product documentation, sample software, and driver software for peripheral control. The company will also roll out evaluation boards and various development environments in collaboration with Arm® ecosystem partners, supporting customers from initial adoption through mass production.Toshiba will continue to expand its lineup of microcontrollers optimized for motor control applications and strengthen development support, contributing to acceleration of customers’ product development.Notes:[1] Advanced Vector Engine 2 (A‑VE2): Performs vector control calculations in hardware at high speed.Advanced Programmable Motor Control Circuit 2 (A‑PMD2): Controls PWM output and motor drive operation.Advanced Encoder Input Circuit 2 (A‑ENC2): Detects encoder signals and obtains rotational position and speed.[2] Conditions for ±1% accuracy:Supply voltage: 2.7V to 5.5V, temperature: −40 to 105°C.[3] TMPM4L4FYAUG, TMPM4L2FYADUG, TMPM4L2FYAQG, TMPM4L1FYAUG[4] TMPM4L4FWAUG, TMPM4L2FWADUG, TMPM4L2FWAQG, TMPM4L1FWAUG[5] Inter‑Integrated Circuit: A serial communication standard for short‑distance, low‑speed communication between ICs.Next-generation home appliances and consumer equipment, including smart appliances and devices with IoT functionalityIndustrial equipment and factory automation systemsOffice and commercial equipmentArm® Cortex®‑M4 core with FPU: operating 80MHz (max)Dedicated motor-control hardwareSecurity functionsFirmware updates during operation (256KB code flash products only, dual‑bank flash)Self-diagnosis functions for functional safetySupply voltage range: 2.7V to 5.5VInternal memory Code flash memory: 128 KB, 256 KB Data flash memory: 64KB (128KB code flash products only) RAM: 32 KB VE RAM: 4KBFour types of small package with 44 to 64 pins (LQFP/VQFN)Main SpecificationsProduct groupM4L GroupPart number[6]TMPM4L4FYAUG TMPM4L4FWAUGTMPM4L2FYADUG TMPM4L2FWADUGTMPM4L2FYAQG TMPM4L2FWAQGTMPM4L1FYAUG TMPM4L1FWAUGCPU coreArm® Cortex®-M4 core with FPU – Memory protection unit (MPU)Maximum operating frequency80MHzInternal oscillatorOscillation frequency10MHz (±1%)Internal memoryFlash (code) (Program/erase cycles: up to 100,000 times)256KB/128KBFlash (data)64KB[7]RAM32KB, with parityVE RAM4KBI/O port51 pins35 pins31 pinsExternal interrupt21 factors, 21 pins13 factors, 13 pins9 factors, 9 pinsDMA controller (DMAC)32 channels30 channels28 channelsTimer function32-bit timer event counter (T32A)5 channels (10 channels if used as 16-bit timer)Communication functionUART6 channels5 channels4 channelsI2C interface version A （EI2C）2 channels1 channelTSPI3 channels2 channelsSMIF1 channelAnalog function12-bit AD converter (ADC)14inputs in 2 units9 inputs in 2 units8 inputs in 2 units8-bit DA converter (DAC)2 channelsComparator (COMP)6 channelsMotor control circuitAdvanced programmable motor control circuit 2 (A-PMD2)1 channelAdvanced encoder input circuit 2 (A-ENC2)1 channelAdvanced vector engine 2 (A-VE2)1 channelOtherCRC calculation circuit (CRC)1 channel (CRC32, CRC16)System functionWatchdog timer (SIWDT)1 channelVoltage detection circuit (LVD)1 channelOscillation frequency detector (OFD)1 channelSecurity functionChip Protection (CPRO), Secure Access Memory (SAM), Non‑Rewritable Flash Protection (NRFP)Debug interfaceJTAG / SW TRACE(2bits)JTAG/SWOperating voltage2.7V to 5.5V, single voltage supplyPackage/PinLQFP64 (10mm×10mm, 0.5mm pitch)LQFP48 (7mm×7mm, 0.5mm pitch)VQFN48 (7mm×7mm, 0.5mm pitch)LQFP44 (10mm×10mm, 0.8mm pitch)Notes:[6] “FY” in the part number indicates 256KB of code flash memory and “FW” indicates 128KB.[7] 128KB code flash products[4] only.This advertisement has not loaded yet.This advertisement has not loaded yet, but your article continues below.Follow the link below for more on the M4L Group.
