HD64F2638F20J Datasheet, PDF (5/1512 Pages) Renesas Technology Corp – Renesas 16-Bit Single-Chip Microcomputer H8S Family/H8S/2600 Series

Preface
This LSI has the internal 32-bit H8S/2600 CPU and includes a variety of peripheral functions
necessary for a system configuration. It serves as a high-performance microcomputer.
The on-chip 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 applied equipment with varied
specifications and early production models to full-scale mass-produced products.
Notes: The H8S/2635 and H8S/2634 are not equipped with a PPG, a PC brake controller, a DTC,
or a D/A converter.

Target users: This manual was written for users who will be using the H8S/2636, H8S/2638,
H8S/2639, H8S/2630, H8S/2635, and H8S/2634 in the design of application
systems. Members of this audience are expected to understand the fundamentals of
electrical circuits, logical circuits, and microcomputers.
Objective:
This manual was written to explain the hardware functions and electrical
characteristics of the H8S/2636, H8S/2638, H8S/2639, H8S/2630, H8S/2635, and
H8S/2634 to the above audience. Refer to the H8S/2600 Series, H8S/2000 Series
Software Manual for a detailed description of the instruction set.
Notes on reading this manual:
• In order to understand the overall functions of the chip
