EMPCD081A
8-Digit Calculator With Tax / Euro Function (Battery / Solar / Dual Power Type)
1 General Description
The EMPCD081A is a single-chip LS1 CMOS calculator for 8-digit 1 memory. Besides,
the EMPCD081A is an arithmetic four standard types of general function (+, −, ×, ÷),
TAX / EURO function, percentage calculation functions, leading zero and trailing zero
suppression, chain calculations, MU calculation, Auto Power OFF available. Dual
power supply operation, wide operating voltage, and lower power consumption make it
suitable for 1.5 solar battery operated calculator.
2 Features
Display : 8-digit of data, 1-digits of sign, error, memory load symbol.
TAX / EURO function available.
Algebraic mode.
Standard 4 function (addition, subtraction, multiplication, division).
Memory calculation.
Automatic percentage operation with add-on discount.
Constant calculation.

C) Error Conditions
ERROR DETECTION
System errors occur when :
The integral part of any calculation result exceeds 8 digits.
The integral part of any memory calculation result exceeds 8-digit or when the
integral part of any addend or subtrahend to memory exceeds 8-digit.
A division by zero is attempted.
ERROR INDICATION
System error :
"0" is indicated in the first-digit position and "E" in the sign-digit position.
The high-order 8-digit of a calculation result is indicated together with "E". The
location of the decimal point corresponds to the result of calculation times le-8, and
no zero shift is performed.
ERROR RELEASE
System error :
A system error can be released by depressing ON/AC key or CE/C key. However the
calculation result is not cleared by CE/C key but is retained.
