ID226075

      The ID226075 has the following features including low drive power;discrete super-fast recovery free wheel diode;high frequency operation;isolated base plate for easy heat sinking.
      The ID226075 is a fully static CMOS 8051 compatible microcontroller designed for high performance. While remaining familiar to 8051 users, it has many new fea- tures. In general, software written for existing 8051 based systems works without modification on the ID226075. The exception is critical timing since the High Speed Micro performs its instructions much faster than the original for any given crystal selection. The ID226075 runs the standard 8051 instruction set. It is not pin compatible with other 8051s due to the time- keeping crystal.
      The power supply of the device must start its ramp from 0.0 V. Functional operating conditions are provided with the DC electrical specifications in Table 5. Absolute maximum ratings are stress ratings only; functional operation at the maxima is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent damage to the device. Caution: All inputs that tolerate 5 V cannot be more than 2.5 V greater than VDDH. This restriction applies to power-up and normal operation (that is, if the MPC852T is unpowered, a voltage greater than 2.5 V must not be applied to its inputs). Guaranteed by design. Not production tested. All digital inputs (DB_, A_, WR, CS, LDAC, and CLR) at GND or VCC potential. All digital inputs (DB_, A_, WR, CS, LDAC, and CLR) at +0.8V or +2.4V. All digital inputs (DB0 to DB13) transition from GND to VCC with WR = VCC.
