Signal Names A0-A20 Address Inputs Q0-Q7 Data Outputs Q8-Q14 Data Outputs Q15A–1 Data Output / Address Input E Chip Enable GVPP Output Enable / Program Supply BYTE Byte-Wide Select VCC Supply Voltage VSS Ground NC Not Connected Internally DEVICE OPERATION The operating modes of the M27V320 are listed in the Operating Modes Table. A single power supply is required in the read mode. All inputs are TTL compatible except for VPP and 12V on A9 for the Electronic Signature. Read Mode The M27V320 has two organisations, Word-wide and Byte-wide. The organisation is selected by the signal level on the BYTE pin. When BYTE is at VIH the Word-wide organisation is selected and the Q15A–1 pin is used for Q15 Data Output. When the BYTE pin is at VIL the Byte-wide organisation is selected and the Q15A–1 pin is used for the Ad- dress Input A–1. When the memory is logically re- garded as 16 bit wide, but read in the Byte-wide organisation, then with A–1 at VIL the lower 8 bits of the 16 bit data are selected and with A–1 at VIH the upper 8 bits of the 16 bit data are selected. |
