This document describes the μPD78F0513D and 78F0515D, which are 8-bit single-chip microcontrollers with on-chip debug functions. These products are not recommended for mass production due to issues with the number of times the flash memory can be rewritten. NEC Electronics does not accept complaints regarding these products.
This manual is intended for user engineers who need to understand the functions of the NEC 78K0/KC2 8‑bit microcontrollers and develop application systems and programs. It covers both standard and graded (A, A2) devices.
The document includes sections on pin functions, CPU architecture, internal blocks, instruction set, interrupts, on‑chip peripherals, electrical specifications, a register index, and revision history, plus contact information for NEC worldwide.
