The final layout area is 301.3um x 321.89um. The fact that the height is now less than a TT slot height is purely coincidental, and probably meaningless. All digital pinouts are on the bottom side and there is only enough space in the TT slot to get maybe 9 routes in from the side, whereas the block has 36 digital I/O. It could be rotated 90 degrees but then the I/O are not in the preferred direction.", "author": { "id": "1365118310701600900", "name": "rtimothyedwards_19428", "discriminator": "0000", "nickname": "Tim Edwards", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/6bcc8e61db497b620550682309ace5d5-D89B4.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "inlineEmojis": [] }, { "id": "1440832935430328501", "type": "Default", "timestamp": "2025-11-19T22:35:41.188+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "@Tim Edwards - How does that compare to the 5V SRAM?", "author": { "id": "169786952432746498", "name": "mithro_", "discriminator": "0000", "nickname": "Tim 'mithro' Ansell", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/9679bb77da48d47c905b398d98a83780-75B68.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [ { "id": "1365118310701600900", "name": "rtimothyedwards_19428", "discriminator": "0000", "nickname": "Tim Edwards", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/6bcc8e61db497b620550682309ace5d5-D89B4.png" } ], "inlineEmojis": [] }, { "id": "1440866745907679253", "type": "Default", "timestamp": "2025-11-20T00:50:02.234+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Area-wise, it's slightly less than 1/2 the area.", "author": { "id": "1365118310701600900", "name": "rtimothyedwards_19428", "discriminator": "0000", "nickname": "Tim Edwards", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/6bcc8e61db497b620550682309ace5d5-D89B4.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [], "inlineEmojis": [] }, { "id": "1440956079985922068", "type": "Default", "timestamp": "2025-11-20T06:45:01.138+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "@Tim Edwards Well it would be easy enough to make a thin wrapper that brings the traces to the preferred routing direction ( and possibly adapts power rails so they connect nicely too ).", "author": { "id": "596068704471482370", "name": "246tnt", "discriminator": "0000", "nickname": "tnt", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/88d17af9d19ab43565b0c46751ef7d12-DFEE5.png" }, "attachments": [], "embeds": [], "stickers": [], "reactions": [], "mentions": [ { "id": "1365118310701600900", "name": "rtimothyedwards_19428", "discriminator": "0000", "nickname": "Tim Edwards", "color": null, "isBot": false, "roles": [], "avatarUrl": "2025-11_media/6bcc8e61db497b620550682309ace5d5-D89B4.png" } ], "inlineEmojis": [] }, { "id": "1441117105536635030", "type": "Default", "timestamp": "2025-11-20T17:24:52.621+00:00", "timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "I thought about that but didn't do a feasibility study. : ) Yet.\nAlso: It's pretty easy to make the smaller SRAM versions, since GF used the same control block exactly, just removed a number of rows and grounded the upper address bits.
