UPD78F9418

PRELIMINARY PRODUCT INFORMATION MOS INTEGRATED CIRCUIT µPD78F9418 8-BIT SINGLE-CHIP MICROCONTROLLER The µPD78F9418 is µPD789417 sub-series product (LCD driver) of the 78K/0S series. This microcontroller features an 8-bit CPU, LCD controller/driver, I/O ports, timers, a serial interface, A/D converters, a comparator, and interrupt control circuits. The µPD78F9418 replaces the internal masked ROM of the µPD789415, µPD789416, and µPD789417 with flash memory, which enables the writing/erasing of a program while the device is mounted on the board. The functions of this microcontroller is described in the following user’s manuals. Refer to these manuals when designing a system based on this microcontroller. µPD789407 and µPD789417 Sub-Series User’s Manual : To be released soon 78K/0S Series User’s Manual, Instruction : U11047E FEATURES Pin-compatible with masked ROM product (other than VPP pin) Flash memory: 32 Kbytes Internal data memory High-speed RAM: 512 bytes RAM for LCD display data: 28 bytes Variable instruction execution time: From high-speed (0.4 µs with the main system clock running at 5.0 MHz) to ultra-low speed (122 µs with the subsystem clock running at 32.768 kHz) 43 I/O ports Serial interface channel: Switchable between three-wire serial I/O and UART modes LCD controller/driver: Up to 28 segment signal outputs Up to 4 common signal outputs Bias switchable between 1/2 and 1/3 Seven A/D converters with an 10-bit resolution Six ti...
