CHAPTER 1 GENERAL
The
µPD78214 sub-series is part of the 78K/II series of eight-bit single-chip microcomputers capable of accessing
an expanded memory space of 1 megabyte. This sub-series consists of the following products.
The
µPD78214 offers a 16-KB masked ROM, 512-byte RAM, highly functional timers/counters, a high-precision A/
D converter, and two independent serial interfaces.
The
µPD78212 is the same as the µPD78214 except that it offers an 8-KB ROM and 384-byte RAM.
The
µPD78213 is the same as the µPD78214 except that it has no built-in ROM.
The µPD78P214 is the PROM version (used in place of masked ROM) of the µPD78214.
• µPD78P214DW: Programs can be written repeatedly (suitable for evaluating an application system).
• Others : A program can be written once (suitable for application systems produced in small lots).
The
µPD78212(A), µPD78213(A), µPD78214(A), and µPD78P214(A) are the special quality versions of the µPD78212,
µPD78213, µPD78214, and µPD78P214, respectively.
