General Description
The GPL833F12A, an 8-bit microprocessor, features 96KB flash memory, 3072 bytes working RAM, 384 bytes LCD RAM, 16 dedicated I/Os, 24 COM/SEG shared I/Os, interrupt/ wakeup controller, four 16-bit timers, SPI interface, one 8-channel SAR ADC with 12-bit resolution for general-purpose application, and automatic display controller/driver for mono LCD. The GPL833F12A contains up to 64 segments and 24 commons, forming a maximum of 1536 dots LCD resolution. GPL833F12A operates over a wide voltage range from 1.8V through 3.6V, and a Low Voltage Reset function to assure system keeps operating properly when power drops below certain level. Moreover, there is one In-circuit emulator (ICE) with two pins to facilitate full speed in-system debug.
