CHAPTER 27 FLASH MEMORY (TWO POWER)
Figure 27-2. Wiring Example of V850ES/KG1 Flash Writing Adapter (FA-100GC-3BA-A) (2/2)
Notes 1. Be sure to connect the REGC pin in either of the following ways.
• Connect to GND via a 10 µF capacitor.
• Directly connect to VDD.
When connecting the REGC pin to GND via a 10 µF capacitor, the clock cannot be supplied from
the CLK pin of the flash programmer.
Supply the clock by creating an oscillator on the board.
2. The pin differs when it is used in a single-power flash memory.
Remarks 1. Handle the pins not described above in accordance with the specified handling of unused pins
(refer to 2.3 Pin I/O Circuits and Recommended Connection of Unused Pins).
When connecting to VDD via a resistor, use of a resistor of 1 kΩ to 10 kΩ is recommended.
2. This adapter is for a 100-pin plastic QFP (14 × 20) package.
3. This diagram shows the wiring when using a handshake-supporting CSI.
