SED1526/28 Series SED1526/28 Series
Dot Matrix LCD Controller Driver SSC5000Series
q Ultra Low Power Consumption q Built-in Power Supply Circuit for LCD q 97 Driver Outputs s DESCRIPTION
The SED1526 series is a single-chip LCD driver for dot-matrix liquid crystal displays (LCD's). 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 17x80-pixel or 33x64-pixel LCD panel. (Note: The SED1526 series are not designed to have EMI resistance.)

Notes: 1. V1 to V5, VOUT, and VREG voltages are based on VDD=0 V. 2. Voltages VDD V1 V2 V3 V4 V5 must always be satisfied. 3. If an LSI exceeds its absolute maximum rating, it may be damaged permanently. It is desirable to use it under electrical characteristics conditions during general operation. Otherwise, an LSI malfunction or reduced LSI reliability may result. 4. The moisture resistance of the flat package may drop during soldering. Take care not to excessively heat the package resin during chip mounting.

For the relationship between CL output frequency and frames, see Figure 7. For the relationship between CL output frequency and power voltage, see Figure 8. For the relationship between CL output frequency and temperature, see Figure 11. The resistance when the 0.1-volt voltage is applied between the SEG and COM output terminals and each power terminal (V1, V2, V3 or V4). It must be within operating voltage (2). RON = 0.1 V/I where, I is the current that flows between power supply and SEG or COM terminal when the 0.1-volt voltage is applied. If the triple voltage by the built-in power circuit are used the VDD primary power must be used within the input voltage range. The V5 voltage can be adjusted within the voltage follower operating range by use of voltage regulator. Applied if the built-in oscillation circuit is used and if not accessed by the MPU. Applied if the built-in oscillation circuit and the built-in power circuit are used, and if not accessed by the MPU. The current flowing through the voltage regulator resistors (R1, R2 and R3) is not included. When the built-in voltage booster is used, the current consumption for the VDD power supply is shown.
