1. GENERAL DESCRIPTION

GPLB13A, a low power 8-bit CMOS microcontroller with advanced

processing technology and mechanism by Generalplus, contains

tons of functionality in a compact package such as SRAM, ROM,

I/Os, an interrupt controller, a timer and a LCD controller/driver.

The amount of 60K bytes of ROM is capable to provide sufficient

space for LCD graphical data.

The 2432 bytes of SRAM are

totally free to users.

In addition, 18 I/Os, timer, LCD driver, NMI

controller, Watch Dog Timer and other features increase the

capability of

driving

sophisticated

functions

and

displaying

fantastic

LCD

graphics.

The

GPLB13A

is

a

high-end

microcontroller that filled with modern technology and strong

backup from Generalplus.

Obviously, it is the most suitable

product to accomplish the demanded functions for you.
