Upd16311 __full__ Jun 2026

The (originally by NEC, now supported by Renesas Electronics) is a Vacuum Fluorescent Display (VFD) controller and driver IC. It is designed to interface between a microcontroller (MCU) and a VFD module, commonly found in consumer electronics from the 1990s–2000s (e.g., VCRs, DVD players, car dashboards, microwave ovens, and hi-fi stereos).

The UPD16311 contains 16 × 11-bit display RAM (16 segments × 11 digits). Addresses 0x00–0x0F correspond to segments (or digits, depending on mapping). Data bits: upd16311
