Q.
What are the differences between the two types of 3803/3804 Group Emulator MCUs: M38049RSS and M38049RLSS? Are there
any special usage notes?
A.
Although their ports on the top of the MCU for the emulator have different specification between M38049RSS and M38049RLSS,
they have the same specifications as MCUs. Please note that M38049RSS has been discontinued and M38049RLSS is the
replacement MCU.
Please take note of the following differences when using M38049RSS or M38049RLSS on your emulator.
<M38049RSS>
1. Set the MCU type switch (SW1) on the emulation pod to RSS/RFS.
2. Leave the VCC (SENSE) cable coming from the emulation pod open.
<M38049RLSS>
1. Set the MCU type switch (SW1) on the emulation pod to RLSS/RLFS.
2. Connect the VCC (SENSE) cable coming from the emulation pod to the target VCC.
Example connection using M38049RLSS chip
Since the M38049RLSS emulation chip is housed in a 64-pin SDIP package, you can connect the chip to the target board directly
or with a pin converter board.
The 3803 Group MCU has 3 package variations and there are 3 options for connecting the chip to the board foot pattern, as
follows:
1. Package Type: 64P4B (1.778mm pitch, 64-pin SDIP)
(1) M38000TL2-FPD -> 28DP-WS (or 28DP-WT) -> M38049RLSS -> 64-pin SDIP socket on the board.
2. Package Type: 64P6N-A (0.8mm pitch, 64-pin QFP)
(1) M38000TL2-FPD -> 28DP-WS (or 28DP-WT) -> M38049RLSS -> M38007T-PRB -> 64-pin LCC socket on the board.
(2) M38000TL2-FPD -> 28DP-WS (or 28DP-WT) -> M38049RLSS -> 64DIP-DMS -> Dummy 64 -> 64-pin LCC foot
pattern on the board
3. Package Type: 64P6Q-A (0.5mm pitch, 64-pin LQFP)
(1) M38000TL2-FPD -> 28DP-WS (or 28DP-WT) -> M38049RLSS -> M38007T-PRB -> 64LCC-QSD -> 64-pin LQFP
foot pattern on the board
