• Manufacturer Part Number: R5F61525
• Description: 32-Bit CISC Microcomputer H8SX Family H8SX/1500 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

The H8SX CPU is a high-speed CPU with an internal 32-bit architecture that is upward-
compatible with the H8/300, H8/300H, and H8S CPUs.
The H8SX CPU has sixteen 16-bit general registers, can handle a 4-Gbyte linear address space,
and is ideal for a realtime control system.
