Type of microprocessor (general-purpose or special purpose, single-chip or bit-slice).
Technology: p-channel MOS, n-channel MOS, CMOS, silicon-on-sapphire, bipolar TTL, Schottky TTL, I2L, ECL. (Knowledge of the technology used gives an idea about the power requirements and speed of the microprocessor.)
