µPD780851(A), 780852(A)
8-BIT SINGLE-CHIP MICROCONTROLLERS
The µPD780851(A) and 780852(A) are products of the µPD780852 Subseries in the 78K/0 Series.
The µPD780851(A) and 780852(A) include a meter controller/driver, sound generator, LCD controller/driver, 8-bit
resolution A/D converter, timer, serial interface, interrupt function, and various other peripheral hardware.
A flash memory version, the µPD78F0852, which can operate in the same power supply voltage range as the
mask ROM version, and various development tools are also available.
Detailed function descriptions are provided in the following user's manuals. Be sure to read them before
designing.
