描述 Description

The EMPCD100 is a single-chip LS1 CMOS calculator for 3 sets store memory (10-digits or 12-digits). Besides, the EMPCD100 is an arithmetic four standard typesof general 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, 10/12-digit selectable LCD display.Dual power supply operation, wide operating voltage, and lower power consumption make it suitable for 1.5 solar battery operated calculator.

特性 Features

Number of display:
10 /12 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:
By algebraic operation.
Basic operations:
Four function, repeat multiplication and division, mixedcalculation, 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 root calculation.
Decimal point method:
Decimal set lock key controls output format. Fixed decimal setting (\"0\", \"1\", \"2\", \"3\",\"4\", \"5\", \"6\"), full floating decimal, and ADD mode (selectable with a switch).
Contents of operation:
1. Floating point mode during operation and key entry that specified only Addition and Subtraction.
2. Specified decimal point mode is valid only for operation results.
3. Round-off when most significant digits have higher priority or at auto shift of rough estimation.
Key rollover method:
Two-key rollover
Error detect display:
1. Key entry exceeding the number of display digits is invalid, but dies not cause an error.
2. If the integer part of an operation result exceeds the number of display digits, a rough estimate is displayed.
3. In the overflow condition, all key except \"C\", \"C/CE\",\"CE\", \"Δ\" keys are inoperative.
Protection:
1. In the overflow condition, all key except \"C\", \"C/CE\", \"CE\", \"Δ\" keys are inoperative.
2. Key chatter protection.
3. Auto-clear at power on
    Auto-clear functions by connecting a capacitor to the RESET pin.
Auto power off function:
6 minutes
Clock source:
Oscillator / clock generator internal to chip.
Others:
1. Keyboard encoding internal to chip.
2. Wide supply voltage range (1.2 to 1.8V).
3. Very low power consumption.
4. Battery / solar power supply.
5. Symbol blinking available.
6. Rate will be kept after AC key pressed.
