April 26, 2006 PCN Number: 0606 PCN Change level: Major Subject: A3P400 Pinout Changes Dear Customer, This PCN provides information on changes in the pinouts for A3P400-PQ208, A3P400FG256, and A3P400-FG484 (Table 1 through Table 3 on page 3). The pinout changes will be incorporated in Actel Libero® Integrated Design Environment (IDE) v7.2, which will be available June 12th. The datasheet for the product family will be changed by April 28th. Following is a summary of the changes. Device: A3P400-PQ208 Changes include the following: • I/O differential pair moved from pins 37-38 to pins 38-39 • Single-ended I/O moved from pin 39 to pin 37 • Second VMV2 was added to pin 53 (previously NC) • I/O differential pair was added to pins 127 and 128 (previously two separate singleended I/Os) • Second VMV0 was added to pin 157 (previously NC) Note: Since an I/O differential pair can be used as two individual single-ended I/Os, the change on pins 127-128 allows an additional differential I/O without changing the number of single-ended I/Os.
