Figure 55: Master Parallel Mode Programming Switching Characteristics
May 14, 1999 (Version 1.6)
Notes: 1. At power-up, Vcc must rise from 2.0 V to Vcc min in less than 25 ms, otherwise delay configuration by pulling PROGRAM
This timing diagram shows that the EPROM requirements are extremely relaxed. EPROM access time can be longer than
500 ns. EPROM data output has no hold-time requirements.
