产品概述
The DS2250T-64-16+ is a soft microcontroller module in 40 pin SIMM package. It is a fully 8051 compatible 8bit CMOS microcontroller that offers softness in all aspects of its application. This is accomplished through comprehensive use of non-volatile technology to preserve all information in the absence of system VCC. The internal program/data memory space is implemented using 64kbytes of non-volatile CMOS SRAM. Furthermore, internal data registers and key configuration registers are also non-volatile. An optional real time clock gives permanently powered timekeeping function. The clock keeps time to hundredth of second using an onboard crystal. All non-volatile memory and resources are maintained for over 10 years at room temperature in the absence of power. The DS2250T has on-chip full duplex serial I/O ports, two on-chip timer/event counters and 32 parallel I/O lines. The device is compatible with industry standard 8051 instruction set.
