PIC16C84 High Performance RISC-like CPU


   The PIC16C84 is a low-cost, high-performance, CMOS, fully-static,
  8-bit microcontroller. The separate instruction and data buses of
  the Harvard architecture allow a 14-bit wide instruction word with
  a separate 8-bit wide data bus. The two stage instruction pipeline
  allows all instructions to execute in a single cycle, except for
  program branches.
  The PIC16C84 fits perfectly in applications ranging form high speed
  automotive and appliance motor control to low-power remote sensors,
  electronic locks,security devices,smart cards and smart toys.
  
  "Features"
    - Only 35 single word instructions to learn
    - Operating speed : DC - 10MHz clock input
                        DC - 400ns instruction cycle
    - 1K x 14bit On-chip EEPROM program memory
    - 64 x 8bit  EEPROM data memory
    - Eight-level deep hardware stack
    - Four interrupt sources
    - 13 I/O pins with individual direction control
    - High current sink/source for direct LED drive 25mA sink
    - 8-bit timer/counter with 8-bit programmable prescaler
    - Power-on reset, Power-up timer, Oscillator start-up timer
    - Watchdog timer
    - Wide operating voltage range : 2.0V to 6.0V
    - Low power consumption <2mA(4MHz)  60uATyp(32KHZ)  26uA(standby)
    - Serial In-System programming

Precision voltage reference IC


    The LH0070 and LH0071 are the ideal choices as absolute 
   reference voltages in personal laboratory.
    The output voltage is established by trimming ultrastable,
   low temperature drift. 
    The devices provide an accurate reference that is virtually
   independent of input voltage, load current, temperature and time.
    The LH0070 and LH0071 are precision, three terminal, voltage
   references consisting of a temperature compensated zener diode
   driven by a current regulator and a buffer amplifier.
    
   "Features"
        - Accurate output voltage
                  LH0070                    10.000V +-0.02%
                  LH0071                    10.240V +-0.02%
        - Single supply operation           11.4V to 40V
        - Low output impedance              0.2ohm
        - Excellent line regulation         0.1mV/V
        - Low zener noise                   20uVp-p

                         -----------
                 +12V --|LH0070     |    output
                        |LH0071     |---- 10.000V
                  GND --|           |     10.240V
