At94k configuration modes

Configuration Modes

  • 2 Configuration Modes controlled by M0 and M2

  • Mode 0: Master serial ( by Configurator )

  • Mode 1: Slave Serial Cascade ( External MCU )


At94k configuration modes

AT94K Configuration I/O

  • Dedicated Pins (all modes)

    • M2, M0, RESET, CON, CCLK.

  • Dual Use Pins

    • INIT (all modes)

    • CSOUT, CHECK, CS1, CS0, A(23:0), D(15:0), HDC, LDC

A (Active)O (Optional)


Mode 0

Mode 0

  • 1, 2, 4 or 8 MHz internally-generated CCLK set through Bitstream options

  • Configurator RESET pin may be tied to either FPGA RESET or INIT pin

  • Mode 1M2M00 0


Mode 1

Mode 1

  • External clocking up to 40 MHz

  • Microprocessor- or EEPROM-driven

  • Mode 1M2M0

  • 0 1


Mode 1 parallel

Mode 1 Parallel

  • Allows independent programming of multiple FPGAs in parallel with the same data

  • Mode 1 M2 M0

  • 0 1


Mode 1 cascade

Mode 1 Cascade

  • Uses CS0 to propagate chip select between cascaded FPGAs; Xilinx devices propagate data

  • M2 M0

  • Mode10 1


Mode 0 with mode 1 cascade

Mode 0 with Mode 1 Cascade


At94k example bitstream

AT94K Example Bitstream

Serial data is read in MSB first. Byte/word entries above are shown MSB<->LSB.

Not applicable to Mode 4.


Cache logic mode

Mode designed for CacheLogic applications

Device treated as an SRAM by the system

Microprocessor treats FPGA as memory mapped I/O.

Simple 24 bit Address and 8 bit Data structure.

At94k memory map and cachelogic

Memory map is architected to support CacheLogic Applications.

Memory Map Pages are all dissociated.

Writing data to one structure has NO impact on any other structure. Key requirement for CacheLogic.

Simple 32 bit interface and 33MHz clocking allow very rapid caching of logic functions.

Symmetrical FPGA architecture results in simple and predictable CacheLogic designs.

Each memory byte has a unique memory map location and can be individually addressed.

Data can be loaded x8 for faster reconfiguration.

In full bitstream, X, Y, Z, Tag information is handled by the on-chip control logic.
