Altera CPLD Max V (P/N: 5M40ZE64C4)

I am supplying this CPLD from two separate power rails (A 1.8V rail and a 3.3V rail). The CPLD uses 1.8V for VCCINT and VCCI02, and uses the 3.3V rail for VCCI01. The 1.8V rail starts up in about 1ms...

Hi Liam,


In the MAX V Device Handbook, under Power-Up Timing topic (page 3-9), it stated that the amount of time required from minimum value VCCINT (1.55V) to enters user mode is 200 microseconds for 5M40ZE64C4. You can refer to Figure 4-5 (page 4-6) for better understanding of power up characteristics of this device.
