MSS0306 Emulation Board
General Description
By Storing digitized voice data and options into 27C010 EPROM, this 9016 board emulates the function of MSS0306 chip although their DC / AC characteristics are not identical. To configure the options of the target chip, you can specify them by entering into text file with text editor on personal computer. Running 9016PACK.EXE on PC you can easily get the compiled file to be put into EPROM. With some jumpers setting, this 9016 board performs versatile applications for your verification before chip fabrication.
Features
It can simulate the function of MSS0306 ( refer to the data sheet, PID 239 06 / 95). Use the battery 1.5V x 4. 3 test pin sets are provided : WR1 ( 3 pins ) , WR2 ( 5 of 8 pins ) and WR3 ( 5 of 8 pins ). 7 LEDs are provided : one for power indicator ( D3 ) and 6 optional for output. Auto power off is provided ( the function is set up by JP3). There are 11 switches on the board : one reset SW, one power on SW, one power off SW, eight push button switches ( TG6~TG8 is reserved ). There are 4 jumper sets on the board : one 2-pin header ( JP3 ), one 3 x 3 - pin header ( JP4, JP7, JP9), one 2 x 6 -pin header (JP6), one 3 x 16 - pin header ( JP5, JP8, JP10 ).
