16-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The
碌
PD784214A, 784215A, 784216A, 784217A, and 784218A are products of the
碌
PD784216A/784218A
Subseries in the 78K/IV Series. Besides a high-speed and high performance CPU, these controllers have ROM,
RAM, I/O ports, 8-bit resolution A/D and D/A converters, timers, serial interfaces, a real-time output port, interrupt
functions, and various other peripheral hardware.
The
碌
PD784214AY, 784215AY, 784216AY, 784217AY, and 784218AY are based on the
碌
PD784216Y/784218Y
Subseries with the addition of a multimaster-supporting I
2
C bus interface.
The
碌
PD78F4218A and 78F4218AY, products with a flash memory instead of the internal ROM of mask ROM
versions, and various development tools are also available.
Detailed function descriptions are provided in the following user鈥檚 manuals. Be sure to read them before
designing.
