UPD780016Y Datasheet, PDF (1/42 Pages) NEC – 8-BIT SINGLE-CHIP MICROCONTROLLER

PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
µPD780016Y, 780018Y
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD780016Y and 780018Y are members of the µPD780018Y subseries of the 78K/0 series microcontrollers.
Besides a high-speed, high-performance CPU, these microcontrollers have on-chip ROM, RAM, I/O ports, timer,
serial interface, real-time output port, interrupt control, and various other peripheral hardware.
The µPD78P0018Y devices including a one-time PROM version and an EPROM version, both of which can operate
in the same power supply voltage range as a mask ROM version, and various development tools are available.
The details of the functions are described in the following user’s manuals. Be sure to read it before starting design.
