TC83220-0020
TC83220-0020 Single-Chip CMOS LSI for FL (fluorescent) Calculator
The TOSHIBA printing/display calculator circuit
TC83220-0020 is 10- or 12-digit calculator on single-chip CMOS
LSI.
TC83220-0020 can drive the printing machine (M2158II/
M2156II; EPSON) with magnet driver circuit, and can drive the
fluorescent display tube with DC-DC converter.
It contains a 4 K-word ROM, a 256 × 4-bit RAM.

The Proposal of Outer Circuit for Tax Rate Holding with Back-Up Battery
Note 7: V1 = 3 V: Battery supply
V2 = 5 V: AC supply
~HOLD pin is pulled down in the LSI, but normally pulled up to VDD.
~RESET pin is pulled up to VDD.
(1)
Setting POWER SW to ON, V2 is supplied to VDD pin, and also to HOLD pin.
Then calculator operates normally.
(2)
Setting POWER SW from ON to OFF, V1 is supplied to VDD pin and VSS is supplied to HOLD pin.
Under this connection, TAX RATE is held.
(3)
Setting POWER SW to ON, V2 is supplied to VDD pin, and also to HOLD pin.
Then calculator operates normally with TAX RATE to be held.
Note 8: V1 (battery) should be supplied to the circuit after V2 (AC) supply, because of prevention from
exhaustion of battery and abnormal operation.
