This handbook describes the Toshiba TMP87C series of high‑speed 8‑bit microcontrollers. It outlines the core architecture, including CPU, ROM, RAM, I/O ports, A/D converter, timers, serial interfaces, and clock generators. Key features such as instruction execution times, interrupt sources, and power‑saving modes are listed.
The document includes pin‑assignment tables, functional descriptions of each pin, electrical characteristics (DC, AC, and recommended operating conditions), and detailed operational descriptions of the CPU core, memory map, and peripheral functions. It also provides absolute maximum ratings and recommended operating ranges for designers.
