Holtek（盛群） 公司的HT16K23是 20x4/16x8 LCD控制驱动器，接纳I2C串行式接口，内建显示内存及RC振荡电路，具有低功耗、高抗噪声及高系统ESD防护能力，工作电压宽2.4V～5.5V，淘汰主版MCU I/O数目、可低落产物整体本钱。HT16K23适用于数字时钟、家电、音响、工业仪表等之LCD显示器的控制及驱动。本京电港论坛文章先容了HT16K23主要特点，方框架图以及多种应用电路。 The HT16K23 is a memory mapping and multi-function LCD controller driver. The Max. display segment numbers in the device are 80 patterns (20 segments and 4 commons) or 128 patterns (16 segments and 8 commons). The Max. key scan circuits are 20*1 matrix or 16*1 matrix. The software configuration feature of the HT16K23 makes it suitable for multiple LCD applications including LCD modules and display subsystems. The HT16K23 supports a hardware interrupt using register setting. The HT16K23 is compatible with most microcontrollers and communicates via a two-line bidirectional I2C-bus. HT16K23主要特点： ●●Logic voltage: 2.4~5.5V ●●Integrated RC oscillator ●●Various display modes CCMax. 20*4 patterns, 20 segments, 4 commons, 1/3 bias, 1/4 duty CCMax. 16*8 patterns, 16 segments, 8 commons, 1/4 bias, 1/8 duty ●●I2C-bus interface ●●Key scan function CCMax. 20*1 matrix key scanning in 20*4 display mode CCMax. 16*1 matrix key scanning in 16*8 display mode ●●16*8 bits RAM for display data storage ●●Selectable hardware interrupt ●●R/W address auto increment ●●Manufactured in silicon gate COMS process ●●28-pin SOP package HT16K23应用： ●●Industrial control indicator ●●Digital clock, thermometer, counter, voltmeter ●●Combo set. ●●VCR set ●●Instrumentation readouts ●●Other consumer application ●●LCD displays |
