solomon systech semiconductor technical data rev 0.1 08/2000 copyright ? 2000 solomon systech limited product information ssd1815z development kit dvk1815z-a0 is a demonstration of ssd1815z working on a (96 x 64 + 1 icon line) panel. it is intended to help users expedite their design-in of solomon lcd driver. package contents dvk1815z-a0 consists of the following: 1) lcd module (96 x 64 + 1 icon line) (DVM1815Z-A0) 2) lcd drawing (optional) 3) programmed 8051 mcu board (evm89c52-a0) 4) 8051 mcu board schematics (evm89c52-a0) 5) demo program in c language (prg1815z-a0) system requirement dvk1815z-a0 is good enough to serve as a standalone demo. 2 x aa 1.5v battery is required for normal operation. for engineering evaluation on the lcd driver and/or lcd panel, a 8051 incircuit emulator (ice) is required. the one solomon systech is using is emmit 8051 ice from syber electronics co ltd. user can get its information from the email: syber@public1.pt lcd module table 1 DVM1815Z-A0 pin assignment pin number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 lcd module v d d r e s n c d / c r / w c s 1 v s s d 0 d 1 d 2 d 3 d 4 d 5 d 6 d 7 n c n c v s s n c n c n c n c n c n c 8051 mcu board v o u t p a - 0 4 p a - 0 5 p a - 0 1 p a - 0 7 p a - 0 6 g n d p b - 0 0 p b - 0 1 p b - 0 2 p b - 0 3 p b - 0 4 p b - 0 5 p b - 0 6 p b - 0 7 p a - 0 0 v o u t g n d + 9 v p 3 4 p 3 5 p 3 6 p 3 7 n c dvk1815z-a0 figure 1 DVM1815Z-A0 outlook the lcd module has been configured as follows 1) size: 96 x 64 + 1 icon line 2) cog package 3) 4x dc-dc converter to generate vee 4) internal feedback resistor which is software programmable is used to generate vl6. 5) 6800 8-bit parallel interface. 6) 24 pins single inline (sil) header is used to connect 8051 mcu board to lcd module. please refer to table 1 for pin assignment. ordering information item ordering part number ssd1815z develop- ment kit dvk1815z-a0 ssd1815z develop- ment module DVM1815Z-A0
2 solomon dvk1815z-a0 rev 0.1 08/2000 8051 mcu board the 8051 mcu board is powered up by 2 x aa 1.5v battery. a 2x dc con- verter (icl7660) is used to generate 4.8v to supply 8051 mcu. this voltage is also regulated by lm317 to generate vout (adjustable from 1.8v to 3.5v) which in turn powers up solomon lcd driver. all logic output from 8051 are down-converted from 4.8v to vout through 74hc4050 non-inverting buffer. user can change vout by tuning t1 (1k trimmer).the mcu board is configured to run at a speed of 4mhz. 4 dummy keys are reserved for developing user- interactive application such as tuning contrast. figure 2 evm89c52-a0 outlook figure 3 DVM1815Z-A0 schematics
