Description
SH6614D
4K 4-Bit Microcontroller with LCD Driver
Features
SH6610C-based single-chip 4-bit microcontroller ROM: 4096 X 16 bits RAM: 512 X 4 bits Operation voltage: 2.4V – 6.0V 8 CMOS bi-directional I/O pins 4-Level subroutine nesting (include interrupts) One 8-bit auto re-load timer/counter Wem-up timer for power-on reset Powerful interrupt sources:
- External interrupts ( INT0 )
- Internal interrupt (Timer0) - Internal interrupt (Base Timer)
- Port's falling edge interrupt: PORTB ( INT1 ) 8-bit Base timer LCD driver: 240 dots (1/8 duty 1/4 bias) or 136 dots (1/4 duty 1/3 bias)
LCD used as scan output Built-in dual tone PSG with one noise generator 2 Clock sources
