UPD780984 Overview
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...
