K61 controller card is based on the K61 controller which has ARM Cortex-M4 core. K61 Controller is used as a processing unit. It operates up to 120MHz. Non-multiplexed mode bus architecture features a 16 bit data and 30 bit address bus. Dimension of the card is double euro size 233.4 mm X 160 mm X 1.6mm.

Controller:

  1. ARM Cortex-M4 core uses ARMv7 architecture and ThumbR-2 ISA.
  2. Operates Up to 120 MHz.
  3. The internal memory is 512/1MB Internal Flash, 128 KB RAM and 16 KB EEPROM.
  4. External Bus interface: Controller features 16 bits address and 16 bit data bus in non-multiplexed mode. In multiplex mode 32 bits address /data can be used. In non-multiplex mode bus address can be extendable up to 30 bit max.
  5. Controller has an internal 4 ADC, 2 DAC, Timers, CAN, USB and an Internal RTC.
