Product Summary

The DS5000T32-16 is a soft microcontroller module. The DS5000T32-16 Soft Microcontroller Module is a fully 8051-compatible 8-bit CMOS microcontroller that offers softness in all aspects of its application. This is accomplished through the comprehensive use of nonvolatile technology to preserve all information in the absence of system VCC. The internal program/data memory space of the DS5000T32-16 is implemented using either 8 or 32 kbytes of nonvolatile CMOS SRAM. Furthermore, internal data registers and key configuration registers are also nonvolatile. An optional real time clock gives permanently powered timekeeping. The clock of the DS5000T32-16 keeps time to a hundredth of a second using an onboard crystal.

Parametrics

DS5000T32-16 absolute maximum ratings: (1)Input Low Voltage VIL: -0.3 to 0.8 V; (2)Input High Voltage VIH1: 2.0 to VCC+0.3 V; (3)Input High Voltage RST, XTAL1 VIH2: 3.5 to VCC+0.3 V; (4)Output Low Voltage @ IOL=1.6 mA (Ports 1, 2, 3)VOL1: 0.15 to 0.45 V; (5)Output Low Voltage@ IOL=3.2 mA (Ports 0, ALE, PSEN)VOL2: 0.15 to 0.45 V.
