sed1526/28 series 1 ssc5000series dot matrix lcd controller driver pf776-03 sed1526/28 series n description the sed1526 series is a single-chip lcd driver for dot-matrix liquid crystal displays (lcds). it accepts serial or 8-bit parallel display data directly from a microprocessor and stores data in an on-chip display ram. it can generate an lcd drive signal independent from microprocessor clock. as the sed1526 series features the very low power dissipation and wide operating voltage range, it can easily realize a powerful but compact display unit having a small battery. a single chip of sed1526 series can drive a 17 80-pixel or 33 64-pixel lcd panel. (note: the sed1526 series are not designed to have emi resistance.) n features l direct data display using the display ram. when ram data bit is 0, it is not displayed; when 1, it is displayed. l large 80 33-bit ram capacity l on-chip lcd driver circuit (97 segment and common drivers) l high-speed, 8-bit microprocessor interface allowing direct connection to both the 8080 and 6800 l supported serial interface l rich command functions (upward compatible to sed1520 series); they are read/write display data, display on/off switching, set page address, set initial display line, set column address, read status, static drive on/off switching, select duty, duty+1, read-modify-write, select segment driver direction, power save, reset, set power control, set electronic controls, clock stop. l on-chip cr oscillation circuit (osc) l on-chip lcd power circuit (the internal and external lcd power supplies are software selectable.) l very low power consumption l flexible power voltages; 2.4 to 6.0 v (for logic) and -13.0 to -4.0v(v dd -v 5 ) l C40 to +85 c wide operating temperature range l cmos process l package: qfp5-128pin (plastic), die form (al pad, au bump) n line up (series specifications: ex. 128-pin flat package) l ultra low power consumption l built-in power supply circuit for lcd l 97 driver outputs model operating clock duty segment common v reg cmos (internal osc) driver driver type pin positions sed1526f 0a 20 khz 1/8, 1/9, 1/16, 1/17 80 17 tpye 1 type a sed1526f aa 20 khz 1/8, 1/9, 1/16, 1/17 80 17 tpye 1 type b sed1526f ea 20 khz 1/8, 1/9, 1/16, 1/17 80 17 tpye 2 type a sed1528f 0a 20 khz 1/32, 1/33 64 33 type 1 type a type 1 v reg (built-in power supply regulating voltage) temperature gradient: 0.17%/ c type 2 v reg (built-in power supply regulating voltage) temperature gradient: 0.00%/ c refer to no. p3 (package pin layout), no. p4 (pad layout) and no. p5 (pad coordinates). an sed1526 series package has one of following subcodes according to its package type (an example of sed1526): sed1526f 0a : qfp5-128pin flat package sed1526d 0 * : bear chip sed1526d 0a having aluminium pad sed1526d 0b having gold bump sed1526t ** : tcp
