6. Connector Pin Assignment
The signals from the evaluation MCU that is mounted on the adapter board are connected to the YQ-
PACK (which has the same pin configuration as the production MCU) via flat cable connectors A
and B on the header board.
The adapter board and header board are connected using the 2 flat cables (standard or long) that are
included with the adapter (which is sold separately). See the operation manual for the adapter board
for details on how to connect the flat cables.
See the data sheet or hardware manual of each of the mass production MCUs for details on the MCU
pins.
■ Pin Assignment
Tables 1 and 2 list the corresponding pin assignments for flat cable connectors A and B, the evalua-
tion MCU on the adapter board, and the production MCU.
The notes in the tables have the following meanings:
*1 : PIDB and PIDA are left unconnected (open) and connected to GND, respectively (for deter-
mining the header connection).
*2 : For the shared ports (P04_1/X1A and P04_0/X0A), set the port selection circuit (CLKSEL0/
1) on the adapter board to match the production MCU port specifications.
⎯ : Unconnected pin (left open).
: UVCC
The pin numbers of the power supply (UVCC) pins on the evaluation MCU are as follows.
VCC = E2, R2, AE4, AG6, AG10, AG13
The pin numbers of the power supply (UVCC) pins on the mass production MCU are as
follows.
VCC = 15, 65, 90
: DVCC
The pin numbers of the power supply (DVCC) pins on the evaluation MCU are as follows.
VCC = A11, D6, D10, F4
The mass production MCU does not have a DVCC pin. Connect the power supply to the VCC
pin on the mass production MCU.
: VSS
The pin numbers of the ground (VSS) pins on the evaluation MCU are as follows.
VSS = A1, A30, D4, D8, D12, D19, D23, D27, H4, H27, M4, M27, W4, W27, AC4, AC27,
The pin numbers of the ground (VSS) pins on the mass production MCU are as follows.
VSS = 16, 44, 66, 91
AG4, AG8, AG12, AG19, AG23, AG27, AK1, AK30
