| T6M19,JT6M19-AS TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic T6M19,JT6M19-AS T6M19, JT6M19-AS Single-Chip CMOS LSI for LCD Calculators The T6M19, JT6M19-AS is single-chip microcomputer for 10-digit + 2-digit scientific calculation. T6M19, JT6M19-AS is the complete single-chip CMOS LSI for calculator with 10 digits, 67 functions, 3 expression and hexadecimal, octal and binary, statistic calculation, fractional number calculation, and logic operation with the following features. Features * 12-digit display plus 2-digit code at the right margin. * Scientific and engineering display. Mantissa 10 digits plus exponent 2 digits plus negative code 2 digits. * Other than above Mantissa 10 digits plus negative code 1 digit. * 13 kinds of special display * M: : E: INV: HYP: BIN: OCT: HEX: SD: DEG: RAD: ( * * * * * * * * * * * * ): Memory Mantissa and exponent minus Error Inverse Hyperbolic Binary mode Octal mode Hexadecimal mode Statistic calculation mode Degree Radian Parenthesis calculation Weight: 1.20 g (typ.) GRAD: Gradian The minus sign of the mantissa is floating minus. The arithmetic key operation in clouding Yx or Y1/x has same sequence as mathematical equation. 6 pending operations are allowed and ( ) are up to continuous 15 levels. Fractional number calculation.
