Only selected functions of the existing µPD78054 Subseries are provided, and the serial interface is enhanced. The µPD780021AY, 780022AY, 780023AY, and 780024AY are the µPD780024A Subseries with a multimaster supporting I2C bus interface, which makes them suitable for AV equipment. Flash memory versions, the µPD78F0034A, 78F0034B, 78F0034AY, and 78F0034BY, that can operate in the same power supply voltage range as the mask ROM versions, and various development tools, are also available. Detailed function descriptions are provided in the following user’s manuals. Be sure to read them before designing. µPD780024A, 780034A, 780024AY, 780034AY Subseries User’s Manual: U14046E 78K/0 Series Instructions User’s Manual: U12326E FEATURES • Internal ROM and RAM Item Part Number ee DataSh DataSheet4U.com Program Memory (Internal ROM) 8 KB 16 KB 24 KB 32 KB 1024 bytes Data Memory (Internal High-Speed RAM) 512 bytes Package • 64-pin plastic SDIP (19.05 mm (750)) • 64-pin plastic QFP (14 x 14) • 64-pin plastic LQFP (14 x 14) • 64-pin plastic TQFP (12 x 12) • 64-pin plastic LQFP (10 x 10) • 73-pin plastic FBGA (9 x 9) µPD780021A, 780021AY µPD780022A, 780022AY µPD780023A, 780023AY µPD780024A, 780024AY • External memory expansion space: 64 KB • Minimum instruction execution time • Expanded-specification products of µPD780021A, 780022A, 780023A, 780024A: 0.166 µs (fX = 12 MHz, VDD = 4.5 to 5.5 V) • µPD780021AY, 780022AY, 780023AY, 780024AY and conventional products of µPD780021A, 780022A, 780023A, 780024A: 0.238 µs (fX = 8.38 MHz, VDD = 4.0 to 5.5 V) • I/O ports: 51 (N-ch open-drain (5 V withstanding voltage): 4) • 8-bit resolution A/D converter: 8 channels (AVDD = 1.8 to 5.5 V) • Serial interface: 3 channels • µPD780021A, 780022A, 780023A, 780024A: UART mode, 3-wire serial I/O mode (2 channels) • µPD780021AY, 780022AY, 780023AY, 780024AY: UART mode, 3-wire serial I/O mode, I2C bus mode • Timer: 5 channels • Power supply voltage: VDD = 1.8 to 5.5 V The information in this document is subject to change without notice.
