7 / 7 page FExternal dimensions (Units: mm) 575 Optical disc ICs BU34675 FExplanation of the hardware (1) Operates of a single power supply (VDD = 2.3 to 5.5V). (2) Memory size ROM: 6144 8 bits RAM: 256 4 bits LCD display RAM : 7 4 bits (3) Instruction time (one cycle instruction) 1.5 µsec (at 4 MHz) (4) Sub-routine nesting: 8 levels . . . . . . . . . . . . . . . . . (5) Interrupts: 5 External 3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Internal (timer counter, serial I / O) 2 . . . . . . . . . (6) ROM data table function (6k data table region) (7) Two power save modes STOP / HALT (8) On-chip 7-segment LCD driver that can drive a wide variety of display types Bias 1 / 3 . . . . . . . . . . . . . . Duty variation 1 / 3, 1 / 4 (programmable) . . . . . . Internal bias resistors (approximately 50k Ω 3 stages) (9) LCD segment output can be switched to CMOS out- put by software. The COM3 pin and upper three segments are one-bit units, and the lower four segments are all selected to- gether. At reset, switches to CMOS low-current output port with low level polarity. (10) Remote control receiver circuit (pulse width mea- surement) (11) On-chip 8-bit timer counter (12) On-chip I / O system makes interfacing with exter- nal LSI easy (LSB first). (13) 8 I / O lines that can be pulled up by software (14) 4 input lines that can be pulled up by software |
