General Description
The LS3013 is a simple micro-controller for LED application. Internal ROM of 256x10, RAM
16x4. It has 4 direct LED output. All output can be mask option as CMOS/NMOS open drain output.
Oscillator is RC or Crystal selected by mask option.
Functional Description
1. RC Oscillator /Crystal
The LS3013 can use either a crystal oscillator or RC oscillator to provide the internal timing by
bonding option.
2. Program ROM
The LS3013 has internal 256x12 bit ROM providing simple operation.
3. Interrupt Control
The LS3013 has 5 different sources of interrupt, namely, POWERUP, F4HZ, F16HZA, F16HZS and
F1HZ. The starting address of the interrupt are as follow :
Interrupt
POWERUP
F1HZ
F4HZ
F16HZA
F16HZS
Address
0xff
0xfe
0xfc
0xf9
0xf2
The system generates 16 interrupts for F16HZS in one second but only 11 interrupts for F16HZA.
The other 5 interrupts goes to F4HZ (4) and F1HZ (1) interrupts.
3. Program RAM
