DS5000-32-16+

Microcontrollers Overview

The DS5000-32-16+ is an 8-bit microcontroller based on the 8051 architecture, manufactured by Analog Devices Inc./Maxim Integrated. It features 32 kbytes of nonvolatile RAM for program and data storage, operating at a maximum crystal speed of 16 MHz. The device utilizes a 40-pin encapsulated package and functions with a +5V power supply within an operating temperature range of 0°C to +70°C. It includes two on-chip timer/event counters, 32 parallel I/O lines, and an on-chip full-duplex serial I/O port.

Microcontrollers Feature Summary

• Nonvolatile memory technology preserves all information in the absence of system VCC, maintaining resources for ten years at room temperature.
• Crashproof operation includes power-fail reset, early warning power-fail interrupt, and watchdog timer capabilities.
• Software security feature executes encrypted software to prevent unauthorized disclosure.
• Compatible with industry standard 8051 instruction set and pinout.

Microcontrollers Applications

• End-system software downloading via on-chip serial port
• In-system modification of program or data memory
• Secure embedded applications requiring code protection

Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm lead-free packaging status indicated by the plus suffix. Check for specific revision errata on the manufacturer website prior to integration. Ensure environmental compliance documentation matches project requirements.

Microcontrollers Selection Notes

Select this component when persistent memory retention across power cycles is required without external battery backup. Suitable for designs needing secure execution environments with encryption support. Verify that the 40-pin package fits the PCB layout constraints. Consider the 16 MHz maximum clock speed against processing requirements.

Microcontrollers Part Context

This part belongs to the DS5000(T) Soft Microcontroller Module family. It represents the variant with 32 kbytes of nonvolatile RAM and no real-time clock functionality. The device integrates nonvolatile CMOS SRAM for internal program and data memory spaces.

Microcontrollers Replacement Considerations

DS5000-32-16 is the non-leaded equivalent. DS5000T-32-16+ includes permanently powered real-time clock functionality. DS5000T-32-16 is the non-leaded RTC variant.
