GPLB27A(OTP)中文资料LCD Controller with 46K Bytes OTP数据手册Generalplus规格书

描述 Description

GPLB27A, an 8-bit CMOS microcontroller with advanced processing technology and mechanism by Generalplus, integrates many features in a compact package, including SRAM, One-Time-Programmable (OTP) ROM, I/Os, an interrupt controller, a timer and a LCD controller/driver.  The amount of 46K bytes of OTP ROM is able to deliver sufficient space for LCD graphical data.  The 2176-bytes of SRAM are all opened to users.  In addition, 14 I/Os, timer, LCD driver, NMI controller, Watchdog Timer, Low Voltage Power Down and other features increase the capability of driving sophisticated functions and displaying fantastic LCD graphics.  The GPLB27A is a high-end microcontroller that filled with modern technology and strong backup from Generalplus.  Obviously, it is one of the most suitable products for LCD applications.  The GPLB27A can also fully emulate the GPLB25B.  For more information about how to program GPLB27A OTP chip, please refer to Generalplus OTP/MTP Writer User's Manual.
