New MCU family of 32-bit ARM-based Flash microcontrollers

29 November 2006 DSP, Micros & Memory

The STR750F is a new series of super-integrated, single-chip, 32-bit ARM7-based MCUs which, according to manufacturer STMicroelectronics, combines into a single device, high performance and low power consumption with ample memory and a full peripheral set.

This series, with a wide range of available configurations, is well suited for virtually any application. Packed with peripherals, the STR750F series offers a host of innovative features for advanced control, security and communication. Based on an ARM7TDMI core, the STR750F series offers high performance with 54 MIPS at 60 MHz and low power consumption down to 10 mA in standby mode.

Features

The STR750F, which can be used with either a 3,3 V or a 5 V power supply, has innovative features such as: a backup clock in case the main quartz oscillator fails; a fast startup capability from reset or low power modes (as low as 55 μs to execute first instruction); flexible and powerful 16-bit timers and PWM timer with fast clock and synchronisation capability; three UARTs that provide hardware support for LIN protocol (master mode); and a serial memory interface (SMI) that enables easy connection to external SPI Flash for data storage.

In low power modes, the automatic wake-up (AWU) feature will enable the micro to wake-up without any external signal, nor need for a quartz.

Benefits

The STR750F family of microcontrollers has an industry standard ARM7TDMI core running up to 60 MHz and demonstrates excellent low power performance through flexible clock management and multiple low power modes with consumption down to 10 μA in standby mode. Extensive firmware support and tools are available. The STR750F library is freely distributed from ST, and STR7 devices are supported by third-party tool and RTOS vendors.

Its rich peripheral set includes: USB, CAN, two x SSP, I2C, three x UART, five x timers, 10-bit ADC and up to 72 GPIO.

Wide choices

The STR750F series is available with up to 256 KB of Flash (retention guaranteed up to 20 years @ 85°C) plus an additional 16 K bank of read-while-write Flash for EEPROM emulation. It is ready for optimum connectivity and control with up to eight communication peripherals including USB and CAN, powerful 16-bit timers and a fast 10-bit ADC. This list is completed by a 4-channel DMA to offload the CPU and a serial memory interface. With its rich set of peripherals, the STR750F family will help customers reduce system cost while addressing all their needs.

Motor control

The STR750F embeds timers and ADC features that are well-suited to tri-phase motor control: PWM timer offers six outputs, dead time generation, edge-aligned and centre-aligned waveforms, emergency stop, synchro capability with ADC, synchro capability with other timers, programmable smoke inhibit feature to protect registers against unwanted writing and a 16-bit timer for encoder interfacing.
