The GPL161001A, a 16-bit architecture LCD controller product, carries the GENERALPLUS newest 16-bit microprocessor, µ’nSP (pronounced as micro-n-SP). The high processing speed assures the µ’nSP™ is capable of handling complex digital signal processes easily and rapidly. The GPL161001A is applicable to the areas of digital sound process and voice recognition. In addition, Liquid Crystal Display (LCD) capability strengthens the GPL161001A to be used in variety of visual applications. The memory capacity includes 128K-word mask ROM plus a 8K-word working SRAM. The LCD controller is able to support up to 20,000 pixels display with 16 gray levels. Other features include 43 programmable multi-functional I/Os, three 16-bit timers/counters, 32768Hz Real Time Clock, Low Voltage Reset/Detection and many others.
