UPD780984A Datasheet 8-BIT SINGLE-CHIP MICROCONTROLLERS

Manufacturer: NEC (now Renesas Electronics)

Overview: DATA SHEET MOS INTEGRATED CIRCUIT µPD780982, 780983, 780984, 780986, 780988, 780982(A), 780983(A), 780984(A), 780986(A), 780988(A) 8-BIT SINGLE-CHIP MICROCONTROLLERS The µPD780982, 780983, 780984, 780986, 780988, 780982(A), 780983(A), 780984(A), 780986(A), and 780988(A) are members of the µPD780988 Subseries of the 78K/0 Series. These microcontrollers are suitable for general-purpose inverter control. The µPD780988 Subseries provides expanded internal ROM and RAM capacities as well as inverter control, timers, and serial interfaces. The µPD780982(A), 780983(A), 780984(A), 780986(A), and 780988(A) are applied a stricter quality assurance program than the µPD780982, 780983, 780984, 780986, and 780988 (standard grade) (NEC classifies these products as special grade in its quality grade classification). A flash memory version, the µPD78F0988, which can operate within the same power supply voltage range as the mask ROM version, and various development tools are also available.
