SK5L1

The SK5L1 is designed as one kind of CMOS 4-bit single-chip micro-computer operated in single 1.5 V power supply. SK5L1 integrates 4-bit parallel processing function, ROM, RAM, display RAM, 15-stage divider, 2 kinds of interrupt and 4-level of subroutine stack. With a built-in LCD drive circuit for maximum of 84/136/168 elements, a 2-mode standby function, and a melody generator circuit in a single chip, it permits the design of system configuration with a minimum of peripheral coponents.

Features of the SK5L1 are:(1)instruction sets: 51;(2)subroutine nesting: 4 levels;(3)built-in main clock oscillator for system clock;(4)signal generation for real time clock;(5)built-in 15 stages divider for real time clock;(6)instruction cycle time: 61 us )typ., at 32.768 kHz);(7)standby function.

The absolute maximum ratings of the SK5L1 can be summarized as:(1)power supply voltage: -0.3 V to 2.0 V;(2)input voltage: -0.3 V to VM+0.3 V;(3)output voltage: -0.3 V to VM+0.3 V;(4)total source output current: 10 mA;(5)total sink output current: 10 mA;(6)operating temperature: 0 to 50 ;(7)storage temperature: -55 to +150 .
