Hi! i wanted to use an IC for a project of mine: It has to have at least 2 external interrupts, and either SPI or I2C; such that the pins of these do no hinder the pins of the interrupt. The objective is to use an IC with as less pins as possible. External Interrupt is not to be of the type IOC. PWM channel is desirable; but not essential. In case PWM doesnt exist; IC must have at least 1 16 bit timer. Flash memory is to be >= 4 kb. Architecture can be 8/16/32 bit; and packaging is also flexible. Anything else is not an issue.
