The new STR750 family from STMicroelectronics is based on the ARM7 thumb microcontroller architecture and contains some sophisticated peripheral features. The STR750 family is noted for it's high flash density and high peripheral integration.

Common features of the STR750 family Flash microcontroller family include:

• STR750 family based on the ARM7-thumb architecture
• Full-spec operation at either 3.3V or 5V
• 54 MIPS (at 60MHz) performance with deterministic prefetch
• 60MHz internal clock (PLL) from 4MHz or 8MHz external crystal or resonator
• 32.768KHz RTC for clock, RTC, or wake up
• On-chip 5MHz "fast start" Oscillator, also can start if main clock is interrupted
• 12µA in STOP mode and 10µA in STANDBY mode
• Max Run Current 90mA @ 60MHz (1.5mA/MHz) (all peripherals enabled)
• I/O pins can sink or source up to 20mA
• 16-bit Watchdog Timer
• Three sophisticated 16-bit timers
• PWM timer for 3-phase motor control
• Up to three UARTs running at 2Mbits/sec with LIN support
• Memory-mapped interface to external serial Flash
• New bit manipulation and bit mask capability with ATOMIC bit set & reset
• -40°C to +105°C temperature range available
• Flash & EEPROM data retention rated up to 20 years at 85°C
• Flash bootloader via UART
• "smoke inhibit feature" blocks out register changes
• A/D injection allows immediate polling of any A/D channel
• Fast 55µsec startup from reset

"The new STR750F reflects ST’s deep expertise in integrating ARM cores into both System-on-Chip solutions and standard microcontroller products, as well as our rich IP portfolio," stated Jim Nicholas, ST’s Microcontroller Division's General Manager. "As a result, the STR750F family offers an unprecedented combination of integration, performance and low power consumption in the 32-bit embedded MCU market."

Features of the first 30 members of the STR750F family include:

• 64KBytes to 256KBytes Flash with 54MIPS access speed
• 16KBytes (flash) EEPROM
• USB
• CAN
• I2C, SPI, etc...
• 40-channel DMA
• Fast 10-bit A/D

The STR750F boasts a free dedicated firmware library for download. Available drivers support USB, DFU, and Mass storage control. Starter kits are available from Keil, IAR, Raisonance, and Hitex.
