Introduction

HDSP-2131 (yellow), HDSP-2179 (orange), HDSP-2132 (high-efficiency red), and HDSP-2133 (green) are eight-digit, 5×7 dot matrix alphanumeric displays. The 5.0 mm (0.2 inch) character height is housed in a standard 7.64 mm (0.30 inch) 32-pin DIP package. On-board CMOS IC decodes 128 ASCII characters permanently stored in ROM. In addition, 16 user-defined symbols can be stored in on-board RAM. Seven brightness levels provide flexibility for adjusting display luminance and power consumption. The HDSP-213x and HDSP-2179 are designed for standard microprocessor interface techniques. Display and special functions are accessed via a bidirectional 8-bit data bus. These features make the HDSP-213x and HDSP-2179 ideal for applications requiring a compact, low-power alphanumeric display.
