This manual introduces the Flash memory programming operations of PD70F3700, PD70F3701, PD70F3702, PD70F3703, PD70F3704, PD70F3706, PD70F3707, PD70F3709, PD70F3710, PD70F3711 and PD70F3712 series V850ES/Hx2 32-bit microcontrollers. It mainly introduces the programming operation procedures, precautions and programming error diagnosis.
The document provides detailed instructions for developing and operating a dedicated flash memory programmer for the NEC V850ES/Hx2 32‑bit microcontroller. It describes the programmer’s working environment, basic operation steps, command and data‑frame formats, and various serial communication modes.
The manual is organized into chapters covering flash programming concepts, hardware pin definitions, power‑on/off sequencing, UART and 3‑line serial I/O modes, command processing, and safety precautions. Appendices include reference circuit diagrams for both the programmer and the target V850ES/Hx2 board. This manual is written in Chinese.
| Programming mode pins | FLMD0, FLMD1 |

| Serial interface pins | TxD, RxD, SI, SO, SCK, HS |
Use antistatic containers, wear a grounded wrist strap, avoid direct hand contact with semiconductor devices, and keep work surfaces properly grounded.
Each unused input pin should be tied to VDD or GND (or through a resistor if it may be used as an output) to prevent floating and possible faults.
