BLX67Z0008 – TBC

The BLX67Z0008 is a programmable read-only memory (PROM) integrated circuit utilizing the Texas Instruments TMS27C512-JL. This device is a 524,288-bit (64K x 8) electrically programmable UV erasable (EPROM) implemented in a dual in-line (DIL) package. The “JL” suffix denotes a specific package type and temperature range, likely a ceramic DIP package suitable for extended temperature operation. The speed grade is indicated by the 200/250NS designation, representing the maximum access time from address valid to data valid. This parameter specifies the read performance of the memory, with the actual access time falling between 200 and 250 nanoseconds depending on operating conditions and specific manufacturing lot variations. The device requires a programming voltage (VPP) for writing data and a supply voltage (VCC) for read operations, both of which must adhere to the specifications detailed in the TMS27C512 datasheet.
