UPD780226

DATA SHEET MOS INTEGRATED CIRCUIT µPD780226, 780228 8-BIT SINGLE-CHIP MICROCONTROLLERS DESCRIPTION The µPD780226 and µPD780228 are members of the µPD780228 Subseries of the 78K/0 Series. The FIP™ (VFD) controller/driver and N-ch open-drain port of the conventional µPD78044H Subseries have been enhanced for the µPD780228 Subseries. A flash memory version, the µPD78F0228, that can operate within the same power supply voltage range as the mask ROM version, and various development tools are under development. The details of functions are described in the following user’s manuals. Be sure to read them before designing. µPD780228 Subseries User’s Manual : U12012E 78K/0 Series User’s Manual Instructions : IEU-1372 FEATURES I/O ports: 72 (sixteen N-ch open-drain I/O ports) Internal high-capacity ROM and RAM Item Part Number µPD780226 µPD780228 Program memory (ROM) 48 Kbytes 60 Kbytes Internal high-speed RAM 1024 bytes Data memory Internal expanded RAM 512 bytes FIP display RAM 96 bytes Minimum instruction execution time can be changed from high-speed (0.4 µs) to low-speed (6.4 µs) FIP controller/driver: 48 display outputs (Universal grid supported) 8-bit resolution A/D converter: eight channels Serial interface: one channel Timer: Four channels Power supply voltage: VDD = 4.5 to 5.5 V APPLICATIONS Compact-type integrated system components, separate-type system components, tuners, cassette tape decks, compact disc players, audio amplifiers, etc. ORDERING IN...
