lsi ls30 13 preliminary specification 4 led controller features * 4 led direct drive * 6 input. * 256 word program control. * 16 x 4 bit ram. * low power consumption * 32768 crystal oscillator/rc oscillator * 3.0v/1.5v operation. general description the LS3013 is a simple micro-controller for led ap plication. 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 optio n. functional description 1. rc oscillator /crystal the LS3013 can use either a crystal oscilla tor or rc oscillator to provide the internal timing by bonding option. 2. program rom the LS3013 has internal 256x12 bit rom providi ng simple operation. 3. interrupt control the LS3013 has 5 different sources of interrup t, namely, powerup, f4hz, f16hza, f16hzs and f1hz. the starting address of the interrupt are as follow : interrupt address powerup 0xff f1hz 0xfe f4hz 0xfc f16hza 0xf9 f16hzs 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
lsi LS3013 2 the system has 16x4bit of program ram (00h to 0fh) with io address as follows. address description initialize 0-0xbh ram undefined 0xch beep control register 0 0xdh ram 0 0xeh s1,s2,s3,s4 0 4. led driver the system has 4 led pad. the led pad can either be an open drain nmos output or cmos output by mask option. note that : writing a 1 to the above address will c ause the corresponding led to turn on (nmos driver) thus equivalent to a low level signal on t he output pad. 5. mask option name description fsysprb power up control 6. ina address ina address description #0 i[0-3] at d[0:3] #1 i[4:5] at d[0:1], d[2:3] always 0 absolute maximum ratings supply voltage vdd - vss..........................0 to 5v input voltage vin.................................v ss to vdd operating temperature top .............-10 c to 60 c storing temperature tst ...................-40 c to 70 c comment stress above those listed under } absolute maximum ratings? may cause permanent damage to the device. these ar e stress rating only. functional operation of this device at these or any other conditions above those indicated in the operational sections of thi s specification is not implied and exposure to absolute maximum rating conditions for extended periods may affect device reliability. d.c. electrical characteristics (gnd = 0v, vdd = 1.5v, ta = 25 c unless otherwise specified)
