STMicroelectronics has added a series of microcontrollers with CANbus interfaces to its ST9 controller family, enabling them to be used in various automotive functions and industrial applications.

Aside from CAN 2.0B active protocol support, the ST92F150JDV1 includes 128KB of single-voltage Flash, on-chip emulated EEPROM, two bxCAN interfaces, and one J1850 BDLC interface. The ST92F250 includes 256KB of Flash and one bxCAN, while the ST92F150CR1 and ST92F150CV1 each have one bxCAN cell with 128KB of Flash.

The on-chip single-voltage Flash memory enables the controllers to run complex applications. It is capable of programming 128KB in <10s and has a data retention period of 15 years. The emulated EEPROM on board is available to protect critical data and offers 100,000 write/erase cycles and 15 years data retention.

Also included in the MCUs are communications peripherals such as one or two serial communications interfaces, one serial peripheral interface, and one or two I?C interfaces. They also integrate a watchdog timer, 16-bit timers with enhanced PWM capabilities, and a 16-channel, 10-bit ADC for analog data acquisition.

The controllers are designed with low-power modes, drawing 10?A during standby and 200?A during operation with RTC capability. They can offer up to 80 flexible I/Os, depending on the package, which includes a TQFP64 and TQFP100.

The ST9 family is available with a complete set of hardware and software development tools including an IDE and a free C compiler. An RTOS, CAN drivers, and a Flash programmer are also available.
