(c) Repetitive rating 25mm x 25mm FR4 PCB, D = 0.05, pulse width 10 s - pulse width limited by maximum junction temperature. Refer to Transient Thermal Impedance graph. CA3420TX Suppliers Figure 1 is an overall block diagram of the CA3420TX. The processor contains three independent computational units: the ALU, the multiplier/accumulator (MAC), and the shifter. The computational units process 16-bit data directly and have provisions to support multiprecision computations. The ALU performs a standard set of arithmetic and logic operations; division primitives are also supported. The MAC performs single-cycle multiply, multiply/add, and multiply/subtract opera- tions with 40 bits of accumulation. The shifter performs logical and arithmetic shifts, normalization, denormalization, and derive exponent operations. P7: 8-bit Input-output port. Each bit can be assigned to input or output. WR: Write strobe output pin for external data memory RD: Road strobe output pin for external data memory WAIT: CPU wait request input pin when accessing external data memory CLKOUT: Output pin for supplying a clock to peripheral circuits PWM: PWM output pin 4. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly for maximum rating, operating supply voltage range, heat radiation characteristics, installation conditions and other characteristics. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Even within the guaranteed ranges, consider normally foreseeable failure rates or failure modes in semiconductor devices and employ systemic measures such as fail-safes, so that the equipment incorporating Hitachi product does not cause bodily injury, fire or other consequential damage due to operation of the Hitachi product. 4.

(Continuous operating for a minimum of one month under lower temp conditions may reduce the brightness to half of the original brightness.) If using in lower temp environments, periodic lamp exchange by Panelview is recommended. The performance of the backlight, for example life time or brightness, is extremely influenced by the characteristics of the DC-AC inverter for the lamp. When designing or ordering the inverter, make certain that poor lighting caused by the mismatch of the backlight and the inverter (miss-lighting,flicker, etc.) do not occur. Once this is verified, the module should be operated in the same condition as it is installed in the instrument. It is required to have the inverter designed to allow the impedance deviation of the two CCFT lamps and the capacity deviation of barast capacitor. |
