MOS INTEGRATED CIRCUIT
µPD780306, 780308
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
µPD780306 and 780308 are products in the µPD780308 subseries within the 78K/0 series, which incorporates LCD
controller/driver, 8-bit resolution A/D converter, timer, serial interface, interrupt functions and many other peripheral
hardwares.
A one-time PROM product capable of operating in the same power supply voltage range as of the mask ROM product,
EPROM product, µPD78P0308, and other development tools are available.
For the details of functional description, refer to the following user’s manual.
