EMPCD200

14/16 DIGIT CALCULATOR (BATTERY/SOLAR/ DUAL POWER TYPE)

GENERALDESCRIPTION

EMPCD200

Desktop Calculator MCU; Number of display:\n 14 /16 digits of data, (including punctuation in each digit) 1-digit of floating minus sign, memory I (M) & memory II (MII) load symbol, error symbol, 3-digits of commas for thousands, TAX symbol, currency exchange (Local, Euro, C1~C5) symbol, GT and sing symbol, etc. Operation methods:\n By algebraic operation.\nBasic operations:\nFour function, repeat multiplication and division, mixed calculation, square calculation, percentage calculation,percent discount and add-on / discount calculation,memory calculation, delta percent calculation, add-modecalculation, mark-up / down calculation, Grand totalcalculation, constant calculation, TAX calculation, EUROexchange, currency exchange and square rootcalculation.\n Decimal point method:\n Decimal set lock key controls output format. Fixed decimalsetting (\"0\", \"1\", \"2\", \"3\", \"4\", \"5\", \"6\"), full floating decimal, and ADD mode (selectable with a switch).\nContents of operation:\n1. Floating point mode during operation and key entrythat specified only Addition and Subtraction.\n 2. Specified decimal point mode is valid only foroperation results.\n 3. Round-off when most significant digits have higherpriority or at auto shift of rough estimation.\n Key rollover method:\nTwo-key rollover\nError detect display:\n1. Key entry exceeding the number of display digits isinvalid, but dies not cause an error.\n 2. If the integer part of an operation result exceeds thenumber of display digits, a rough estimate is displayed.\n 3. In the overflow condition, all key except \"C\", \"C/CE\",\"CE\", \"Δ\" keys are inoperative.\nProtection:\n1. In the overflow condition, all key except \"C\", \"C/CE\", \"CE\", \"Δ\" keys are inoperative.\n2. Key chatter protection.\n3. Auto-clear at power on\n??? Auto-clear functions by connecting a capacitor to the RESET pin.\nAuto power off function:\n5 minutes\nClock source:\nOscillator / clock generator internal to chip.\nOthers:\n1. Keyboard encoding internal to chip.\n 2. Wide supply voltage range (1.2 to 1.8V).\n 3. Very low power consumption.\n 4. Battery / solar power supply.\n 5. Symbol blinking available.\n 6 Rate will be kept after AC key pressed.\n\n;

\nThe EMPCD200 is a single-chip LS1 CMOS calculator for 3 sets store memory (14-digits or 16-digits). Besides, the EMPCD200 is an arithmetic four standard types ofgeneral function (+, ?, x, /), TAX function, Euro & 5 sets currency exchange,percentage calculation functions, leading zero and trailing zero suppression, chain calculations, Mark up/down (MU/MD) & Delta percent (Δ%) calculation, Grand Total(GT) calculation, Auto Power OFF available, 14/16-digit selectable LCD display. Dualpower supply operation, wide operating voltage, and lower power consumption makeit suitable for 1.5 solar battery operated calculator.
