Digital input/output LFYB series dedicated expansion board 48bit DIO board (YHA11) LFYBEX11
L&F Co., Ltd.
About This Product
Expansion board exclusively for the LFYB series. Implements two PPI (8255) and can expand DIO with TTL level 48 bits. Up to 4 boards can be stacked together. Compatible boards include LFYBH83048/H83064/SH7084.
■Note
This board is the same product that was developed and sold by the former Yellow Soft Co., Ltd., which went out of business, as a prototype and for learning purposes, and which our company continues to produce. This is a product that originally did not have environment-related parameters such as RoHS, and we are unable to provide it, so please be aware of this before considering it.
■Product features
This is a TTL level 48-bit I/O board that implements two PPI (8255) equivalent products. Used on top of a CPU board such as LFYBH83048/H83064/SH7084 with a PC/104 connector. Up to four boards can be stacked, and even when stacked, the CPU signal line remains on top of the I/O. It is the same size as a CPU, compact, low cost, and can be used as is from prototypes to mass-produced products.
a) Since two CQ82C55s are installed, 48-bit I/O can be controlled with one board. Solder the pin header to the CPU board and stack it on top of it.
b) Since the board address can be set using the dip switch, I/O control can be performed by stacking up to 4 boards (192 bits) by dividing the address.
c) CQ82C55 can programmably set input and output in 8-bit (4-bit for C port) units.
d) All ports are pulled up with 22KΩ.
e) The input/output connectors have a 30-pin and 26-pin design to prevent incorrect insertion.
■I/O connector
・2.54mm pitch 2 rows x 15 = 30 pins
・On-board connector: Right angle type pin header HIF3FC-30PA-2.54DS
・Compatible socket
・HIF3BA-30D-2.54R (with guide to prevent incorrect insertion) or HIF3BA-30D-2.54R-CL (with pull-out tab), both manufactured by Hirose Electric Co., Ltd.
