GPL133A中文资料256KB LCD CONTROLLER数据手册Generalplus规格书

描述 Description

The GPL133A, an 8-bit microprocessor with advanced CMOS technology, offers a wild assortment of features, including a large size of RAM and ROM, I/Os, PWM audio output, UART, low voltage detector and plus many others. The amount of 256K-byte of ROM and 4K-byte of RAM offer lots of room to store plenty of data and program. Up to 6.0MHz running speed ensures the sophisticated functions and graphics are performed in a flawless way. The 32 programmable I/Os arise the abilities in driving and communicating with other components. The built-in UART facilitates the data communication between devices. In addition, the low voltage detector reports a battery status that gives a clear signal of when to change the battery. The GPL133A includes two sets of 16-bit TIMER/COUNTER circuit that can be programmed as two independent timers, or a 32-bit timer. Furthermore, LCD interface structure can be programmed to implement varieties of dot matrix panel applications from 48*32 to 160*80 with single or more LCD drivers. Other impressed features such as external interrupt sources, sleep mode, key wakeup capability, and E.L driver make GPL133A ranked the best cost and performance ratio in the LCD-controller industry. With fully loads of GENERALPLUS state-of-the-art technology and commitment, users are guaranteed to receive completed and satisfactory support.
