1.2.7 Keyboard controller Hitachi H8/3437
The H8/3437 Series is a series of high-performance microcontrollers with a fast H8/300 CPU core and a set of on-
chip supporting functions optimized for embedded control. These include ROM, RAM, four types of timers, a serial
communication interface, optional I2C bus interface, host interface, A/D converter, D/A converter, I/O ports, and
other functions needed in control system configurations, so that compact, high-performance systems can be
implemented easily. The series includes the H8/3437 with 60-kbyte ROM and 2-kbyte RAM, the H8/3436 with 48-
kbyte ROM and 2-kbyte RAM, and the H8/3434 with 32-kbyte ROM and 1-kbyte RAM.
The H8/3437, H8/3436, and H8/3434 are available in mask-ROM versions. The H8/3437 and H8/3434 are also
available in ZTAT™*1 (zero turn-around time) versions, providing a quick and flexible response to conditions from
ramp-up through full-scale volume production, even for applications with frequently-changing specifications. In
addition, the H8/3434 and H8/3437 have F-ZTAT™*2 (flexible-ZTAT) versions with on-board programmability.
