SED1570d 0a 1 ssc5000series dot matrix high duty lcd driver pf783-02 SED1570d 0a n description the SED1570 is an 80 output segment (column) driver with an internal display ram. this drive is suitable for driving a dot matrix lcd panel; from a mid-range capacity dot matrix lcd panel to a cga class dot matrix lcd panel. this device is used with the sed1635. the display data is stored in the internal display ram and an lcd panel drive signal is generated. as a result, this device allows configuration of an ultra low power display system since the display data is not transferred unless the display is changed. in addition, the logic power is low voltage; a wide range of applications is possible. n features l display duty cycle: 1/64 C 1/200 l lcd driver output: 80 out l internal display ram: 200 80 bits l slim chip l ultra low power consumption l power v dd C v ss 2.7 v to 5.5 v v dd C v ee 8.0 v to 20 v l high speed and low power date transfer by the 4-bit bus enables chain method l non-bias display off function l output shift direction-pin selection l adjustable lcd power offset bias for v dd level l package: die form SED1570d 0a (al pad) SED1570d 0b (au bump) n pad dimensions chip size 8.04 mm 3.51 mm pad center size 100 m m 100 m m pad pitch 170 m m (min.) chip thickness 400 m m 25 m m (al pad) bump size 92 m m 82 m m pump pitch 170 m m (min.) chip thickness 525 m m bump height 17 to 28 m m (reference) 31 1 50 81 32 49 99 82 y x d1570d l 80 output segment driver l built-in display ram 80 200 bits l self-refresh function
