Product Overview:

This LSI has the internal 32-bit H8S/2600 CPU and includes a variety ofperipheral functions necessary for a system configuration. It serves as a high-performance microcomputer.
The built-in peripheral devices include a 16-bit timer pulse unit (TPU), a programmable pulse generator (PPG), a watchdog timer unit (WDT), a serial communication interface (SCI), an A/D converter, a motor control PWM timer (PWM), a PC brake controller and I/O ports. It also has an internal data transfer controller (DTC), which performs high-speed data transfer without using the CPU, thus enabling the use of the LSI as an embedded microcomputer in various advanced control systems. Two types of internal ROM are available: flash memory (F-ZTAT™) and mask ROM. The LSI can be used flexibly in a wide range of applications from appliedequipment with varied specifications and early production models to full-scale mass-produced products.
