M-78F0714 Micro-Board for µPD78F0714 Microcontroller
4.2 SB× Array: Flash Interface Signal Selection
4.3 2JP6: VDD_KX Selection
4.4 2JP5: Main Clock Selection Jumper
The SB× array (solder blobs) is used to connect the flash programming interface signals on the 16-
pin 2J2 header to appropriate pins of the µPD78F0714. The default settings shown in Figure 4 are
configured for flash programming.
The M-78F0714 micro board can derive power from two sources: EXT_VDD, a user-supplied
external power source between 4.0–5.5V
IO board’s two 100-pin connectors, 2P1 and 2P2.
A 20 MHz crystal oscillator (2Y2) is mounted on the M-78F0714 micro-board as the main clock. If
desired, it can be removed and replaced by a different model. A Citizen HC49US Series quartz
crystal oscillator that uses 18-picofarad (pF) biasing capacitors for a range of frequencies is
recommended.
