Designed for single-chip engine control units and I/O intensive automotive application, the ST10F280 16-bit microcontroller chip from STMicroelectronics features up to 143 GPIOs in eight ports, and 512KB of embedded Flash memory that has a retention of 20 years and a lifespan of 100,000 cycles over the entire automotive temperature range.

The 5V device can have an additional 18KB of internal RAM that enables common applications to be implemented without additional chips. For applications requiring large external memory the ST10F280's external bus controller can address up to 16MB.

The chip also embeds a 40MHz DSP controller that executes DSP instructions in 50ns. The DSP algorithms are supported by an integrated 40-bit wide multiply-accumulate unit and a true DSP instruction set that eliminates software bottlenecks.

Fabricated using the company's 0.35?m process, the ST10F280 is provided with standard microcontroller functions, such as interrupt handling with additional eight-channel DMA for single cycle data transfers, timers, serial channels, ADC, and pulse width modulators.

In addition, the 208-lead BGA device includes automotive-specific peripheral blocks, such as two CAN interfaces and two watchdog timers, to monitor the clock oscillator and program execution.

Toolchain support for the ST10F280 is provided by Tasking's C++/C/ECC compiler toolchain and Keil's C compiler. Emulation support is provided Lauterbach, Hitex, and Nohau.
