SMP:
- The SMPbus system is based on the 8080/8085/8088 processors
- SMPbus is a bus system with monomaster capability and a synchronous bus protocol
- An 8-bit format in a 64 kByte address space is used for the data transfer (16-bit addresses)
- The specification calls for a clock frequency of 8 MHz
SMP-M:
- Like the SMPbus, SMP-M is synchronous and has monomaster capability. The SMP-M bus includes 16-bit wide data words and can address a memory range of 1 MByte
- SMP-M bus is an extended SMP bus. The extensions include a total of 13 signals
SMP16:
- SMP16 bus is a synchronous monomaster system with an 8/16-bit data width and 20-bit address bus
- SMP16 can address a memory range of 1 MByte. It provides 64 kByte for direct input/output and 4 kByte for memory mapped in put/output (MMIO)
- Depending on the assemblies uses, 8 or 16-bit data transfer is possible. 8 cascadeable interrupt lines are integrated in the system
Standard Bus 1:1:
- Conduction board pattern: 60 or 90 bus signal lines, rows A2 to A31, rows C2 to C31 connected in parallel. The screen lines are connected to A32, B32, C32 (GND)
- Two power supply lines, row ABC1 (power supply), row ABC32 (GND line)
- Four additional power supply lines for user writing
- Up to two adaptation fields above the connector field (depending on overall bus length)
ECB bus:
- The ECB bus system is an 8-bit parallel bus designed for the Z80 microprocessor family
- Since there is no DIN/IEC/IEEE specification, several ECBbus pin assignments are on the market
- The Hartmann ECBbus matches the Kontron ECB assignment
- Its special layout design and large number of power supply potentials, the Hartmann ECBbus is suitable for universal use, including customer-specific applications
