Manufacturer: Siemens
Series: SIMADYN D
Category: Processor Module (32-Bit CPU)

Physical Dimensions and Weight

The Siemens 6DD1606-1AA0 measures 12.5 inches in length. Its width reaches 1.6 inches for single-slot occupancy. The board thickness sits at 6.0 inches including components. This standard form factor fits into any SIMADYN D rack. The total weight comes to approximately 0.65 kilograms.

Technical Specifications and Processing Power

This processor module uses a 32-bit RISC microcontroller architecture. It operates at a clock speed of 25 MHz. The module stores user programs in 1MB of battery-backed RAM. Additionally, it holds 512KB of flash memory for firmware storage. The typical cycle time reaches 300 microseconds for 1,000 instructions.

Energy Storage and Data Retention

The Siemens 6DD1606-1AA0 includes a replaceable lithium battery for RAM backup. This battery provides 12 months of data retention without external power. A supercapacitor array adds 168 hours of temporary backup during battery changes. Therefore, you can replace the battery without losing critical parameters. The module also stores boot code in non-volatile flash memory.

Interface and Connectivity

This processor module features multiple communication interfaces for flexibility. Two RS-232 serial ports connect to programming terminals and HMIs. The front panel includes an 8-position DIP switch for configuration. Six LED indicators show RUN, STOP, and diagnostic status clearly. You can access all ports without removing the module from the rack.

Component Layout and Memory Architecture

The Siemens 6DD1606-1AA0 contains 195 discrete components on an eight-layer PCB. Key parts include the main CPU chip and 24 memory ICs. The memory architecture divides into three distinct banks. Program blocks occupy 512KB of the address space. Data blocks use another 256KB, and system variables use 128KB. The remaining 128KB serves communication buffers and diagnostics.

Integration and Compatibility

Use the Siemens 6DD1606-1AA0 with any SIMADYN D I/O rack. It works alongside 6DD1607-0AA0 or 6DD1608-0AA0 I/O modules. This processor supports all standard SIMADYN D configuration software.
