8-BIT SINGLE-CHIP MICROCONTROLLER
PRELIMINARY PRODUCT INFORMATION
MOS INTEGRATED CIRCUIT
μ
PD78F9217Y
The
μ
PD78F9217Y is
μ
PD789217Y sub-series products of the 78K/0S series.
These microcontrollers feature an 8-bit CPU, I/O ports, timers, a serial interface, A/D converters, interrupt control
circuits, and EEPROM
The
μ
PD78F9217Y differs from the
μ
PD789216Y and
μ
PD789217Y in that it uses flash memory rather than internal
masked ROM.
Flash memory can be written or erased electrically without having to remove it from board. Therefore, the
μ
PD78F9217Y is best suited for prototypes in system development, low-volume production, or systems likely to be
upgraded frequently.
TM
.
The functions of these microcontrollers are described in the following user’s manuals. Refer to these
manuals when designing a system based on any of these microcontrollers.

PD789217Y Sub-Series User’s Manual
78K/0S Series User’s Manual, Instruction
: To be created
: U11047E
FEATURES
Pin-compatible with masked ROM products (other than the V
PP
pin)
Flash memory: 24 Kbytes
Internal high-speed RAM: 512 bytes
EEPROM: 128 bytes (can be read/written by program)
Main system clock: RC oscillation
Variable minimum instruction execution time: High-speed (0.5
μ
s) (with the main system clock running at 4.0 MHz)
and very low speed (122
μ
s) (with the subsystem clock running at 32.768 kHz)
31 I/O ports
Eight A/D converters with a 10-bit resolution
Two serial interface channels:
Switchable between three-wire serial I/O and UART modes
System management bus (SMB)
Six timers:
16-bit timer counter
Three 8-bit timer/event counters
Clock timer
Watchdog timer
16-bit multiplier
Low-voltage detection circuit
Power supply voltage V
DD
: 1.8 to 5.5 V
