20 / 46 page  20 Altera Corporation MAX 9000 Programmable Logic Device Family Data Sheet Programming Sequence During in-system programming, instructions, addresses, and data are shifted into the MAX 9000 device through the TDI input pin. Data is shifted out through the TDO output pin and compared against the expected data. Programming a pattern into the device requires the following six ISP stages. A stand-alone verification of a programmed pattern involves only stages 1, 2, 5, and 6. 1. Enter ISP. The enter ISP stage ensures that the I/O pins transition smoothly from user mode to ISP mode. The enter ISP stage requires 1ms. 2. Check ID. Before any program or verify process, the silicon ID is checked. The time required to read this silicon ID is relatively small compared to the overall programming time. 3. Bulk Erase. Erasing the device in-system involves shifting in the instructions to erase the device and applying one erase pulse of 100 ms. 4. Program. Programming the device in-system involves shifting in the address and data and then applying the programming pulse to program the EEPROM cells. This process is repeated for each EEPROM address. 5. Verify. Verifying an Altera device in-system involves shifting in addresses, applying the read pulse to verify the EEPROM cells, and shifting out the data for comparison. This process is repeated for each EEPROM address. 6. Exit ISP. An exit ISP stage ensures that the I/O pins transition smoothly from ISP mode to user mode. The exit ISP stage requires 1ms. Programming Times The time required to implement each of the six programming stages can be broken into the following two elements: ■ A pulse time to erase, program, or read the EEPROM cells. ■ A shifting time based on the test clock (TCK) frequency and the number of TCK cycles to shift instructions, address, and data into the device. |
