Re: TI-H: Internal memory expansion III
Did you actually get it to work yet?
------------------------------------------------------------
The memory chip in the TI-85 is the:
SRM20256LLM10
F4XM 885
/\/\ JAPAN
It is 28-pin SOIC and it is a:
32k*8 CMOS SRAM
------------------------------------------------------------
I looked in Mouser, and I found these that might work:
*M638032-15E SGS MICRO PRODUCT 32KX8 CMOS SRAM 15NS
*M638032-15ETR SGS-THOMSON NON-CATALOG PRODUCT 32KX8 CMOS SRAM 15NS
*M638032-20E SGS MICRO PRODUCT 32KX8 CMOS SRAM 20NS
*M638032-20ETR SGS-THOMSON NON-CATALOG PRODUCT 32KX8 CMOS SRAM 20NS
These are like $10-11 each
------------------------------------------------------------
In digikey, i didnt find any CMOS SRAM
------------------------------------------------------------
In Allied Electronics, i found an exact match:
CMOS SRAM 32k*8 100NS 28 Lead SOG
Part #: MS62256L-10FC
But when i went to get a price in the online catalog, it said
that they didnt have the product.
------------------------------------------------------------
Can someone help me find a US supplier of a chip that will work,
and at a good price?
