The MCU Board 41x contains an Oki pre-programmed 16bit Flash MCU and EPROM. If customers do not have their own MCU and would like to hear the M9841 sound quality Oki offers the MSM9841 Demo Board and MCU Board 41x (x=A, B, C. See the data sheet for more details) as a set. Customers can also use the MSM9841 Demo Board that has an Oki amplifier IC, a speaker jack and a connector to an MCU.

* The AR205 does not support MSM9810.
** Since Oki Semiconductor installs a standard code in EPROMs, customers will need an EPROM Eraser to erase the EPROMs before programming
