AN-1043 Delay cell configuration with auto powerdown

Using a counter is a good method to create long time delays. However, delay times are often too limited because counter data may not be large enough. GreenPAK solves this by providing large configurable counters. This note describes the behavioral differences among the GreenPAK chips, and the suggested circuit configuration. This is particularly important to preserve the accompanying RC OSC powerdown feature for power savings.
