Description

The GMS81504 is a high-performance CMOS 8-Bit Microcontroller with 4K bytes of ROM. The device is one of GMS800 family. The HYUNDAI GMS81504 is a powerful Microcontroller which provides a highly flexible and cost effective solution to many embedded control applications. The GMS81504 providesthe following standard features: 4K bytes of ROM, 128 bytes of RAM, 23 I/O lines(21 lines for 28SOP), 16-Bit or 8-Bit timer/counter, a precision analog to digital converter, on-chip oscillator and clock circuitry. In addition, the GMS81504 supports power saving modes to reduce power consumption.
