MSC7170-xx

• Able to display 5 * 7 dot matrix type characters of a maximum of 16 digits * 2 lines (when MSC1164/1165 is used)
• The number of display digits selectable in a range of 1 digit * 2 lines to 16 digits * 2 lines
• Standby function
   - Combination of the MSC7171 grid driver and the MSC7170 decreases grid driver current during the standby mode of the driver.
• Display intensity selectable by 10-bit digital dimming
• Display characters selectable from among 256 types by internal PLA User programmable, mask option
• 8-bit synchronous serial data transfer SPI interface
• 5 * 6 keyscan circuit
• Driver output current (IOH) : 1 mA (SEG1 to SEG35) : 15 mA (SEG36)
• Supply voltage: V_DD = 5 V±10% : V_DISP = 60 V (max.)
• Package:
   - 100-pin plastic QFP (QFP100-P-1420-0.65-BK) (Product name: MSC7170-xxGS-BK) xx indicates the code number.

Notes: *1 Voltage that can be applied to GND
*2 Stresses beyond the rating may cause permanent damage to the device.
*3 Package thermal resistance between junction and atomsphere. Junction temperature T_j in the following expression must not exceed 150°C: T_j = P * R_j-a + T_a (P: maximum IC power consumption)

The MSC7170 is a display controller/segment driver containing a 5 × 6 keyscan circuit, designed for a 5 × 7 dot matrix type vacuum fluorescent (VF) display tube.

Use of the MSC1164/1165 grid driver allows a maximum of 16-digit pair to be displayed, or use of the MSC7171 grid driver allows a maximum of 12 digit pairs to be displayed.
