97C2051 datasheet



The GMS97C2051 / GMS97L2051 / 97C2051 is a high-performance CMOS 8-bit microcontroller with 2Kbytes of programmable EPROM. The device is compatible with the industry standard MCS-51 TM instruction set and pinout.

The  Hynix semiconductor  GMS97C2051/GMS97L2051 is a powerful microcontroller which provides a highly flexible and cost effective solution to many embedded control applications. The GMS97C2051/GMS97L2051 provides the following standard features:2Kbytesof EPROM, 128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator and clock circuitry. In addition, the GMS97C2051/GMS97L2051 supports two software selectable power saving modes.

The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The Power Down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset.
