Product Attributes

Introduction

This series is ideal for applications requiring alphanumeric dot matrix information of eight or more characters to be displayed attractively. These devices are 8-digit, 5×7 dot matrix alphanumeric displays, all housed in a standard 15.24 mm (0.6 inch) 28-pin DIP package. The onboard CMOS IC decodes 128 ASCII characters permanently stored in ROM. In addition, 16 programmable symbols can be stored in onboard ROM, providing considerable flexibility for displaying additional symbols and icons. Seven brightness levels offer versatility in adjusting display luminance and power consumption. The product is designed with a standard microprocessor interface. Display and special functions are accessed via a bidirectional 8-bit data bus.
