• Manufacturer Part Number: h8s-2646
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

The H8S/2646 Group is a series of high-performance microcontrollers with a 32-bit H8S/2600
CPU core, and a set of on-chip supporting functions required for system configuration.
This LSI is equipped with a 16-bit timer pulse unit (TPU), programmable pulse generator (PPG),
watchdog timer (WDT), serial communication interface (SCI), A/D converter, motor control
PWM timer (PWM), LCD controller/driver (LCDC), and I/O ports as on-chip supporting modules.
In addition, data transfer controller (DTC) is provided, enabling high-speed data transfer without
CPU intervention. This LSI is suitable for use as an embedded processor for high-level control
systems. Its on-chip ROM are flash memory (F-ZTAT™ * ) that provides flexibility as it can be
reprogrammed in no time to cope with all situations from the early stages of mass production to
full-scale mass production. This is particularly applicable to application devices with
specifications that will most probably change.
Note: * F-ZTAT is a trademark of Renesas Technology Corp.
