SAB-C165-LM 3V HA

Embedded - Microcontrollers

The SAB-C165-LM 3V High-Availability (HA) microcontroller is a powerful and highly integrated system-on-chip (SoC) solution designed for applications requiring high reliability and guaranteed service availability in mission-critical applications. The SAB-C165-LM consists of two dedicated redundant embedded microcontroller systems with a total of three Integrated Processing Units (IPUs): the main core (M- CPU) and two CPUs in a modified Harvard architecture. The M-CPU implements latest embedded microcontroller technology from Infineon Technologies and its partners and is supported by an extensive range of on-chip peripherals, allowing the implementation of innovative solutions.

All three processors feature a 16-bit Harvard architecture supporting operations up to 40 MIPS, used for executing device level functions. All three CPUs share internal program and data memories and the SAB-C165-LM provides up to 256 kB combined RAM and Flash program memory, additionally Flash program memory up to 16 MB is available. An additional memory option is a 32 bit SDRAM/SRAM interface with clock speeds up to 133 MHz. The SAB-C165-LM also provides a wide range of system-peripherals including 3 UARTs, 4 SPI/SSI buses, 4 SMbus/I2c-buses, an 8 channel Direct Memory Access (DMA) Controller and 6 Timer including a Segment Timer.

The main features of the SAB-C165-LM 3V HA microcontroller include:

• Up to 40 MIPS performance
• Two dedicated redundancy CPU’s in a modified Harvard architecture
• 256 kB to 16 MB of total program memory
• 16-bit Harvard architecture
• Up to 6 Timers and 4 SMBus/I2c-buses available
• 8-channel DMA Controller
• Support for SDRAM/SRAM interface with up to 133 MHz clock speed
• Power management features like deep-sleep, peripheral off, power lock and power controller

The SAB-C165-LM 3V HA can be used in applications requiring high availability, reliable operation, and significant system performance and throughput. The SAB-C165-LM is ideal for highly reliable embedded systems such as robotics and control systems, mission-critical systems in medical, aerospace and industrial automation, as well as automotive embedded systems. The SAB-C165-LM also supports multiple protocols and standards, allowing integration into an existing system.

The SAB-C165-LM 3V HA microcontroller works on the principle that two identical processors are used, each containing the same program. When one of the processors fails, the other processor is available to pick up the work and maintain the continued operation of the system. The two processors are connected through a communication bridge, which allows them to monitor each other and pass data back and forth.

The advantage of this system is that if one of the processors fails, the system can continue to run with no interruption, as the other processor takes over the workload. Additionally, the two processors are always running in tandem, so that if either one fails, the process can switch to the other processor immediately.

In addition to its main redundancy features, the SAB-C165-LM 3V HA microcontroller also includes protection features, including protection against over-temperature, over-voltage, undervoltage, power-On reset (POR), brown-out reset (BOR), and reset synchronization. The protection features guard against unexpected and premature failure of the system and help to ensure maximum system availability, reliability and performance.

The SAB-C165-LM 3V HA microcontroller is an ideal solution for a wide variety of embedded systems, offering reliable and highly available operation with significant system performance. The SAB-C165-LM can help to reduce system development costs, increase system efficiency and ensure maximum system availability.
