Functional Description
CY7C1062G and CY7C1062GE are high-performance CMOS
fast static RAM devices with embedded ECC. Both have three
chip enables, giving easy memory expansion features. The
CY7C1062GE device includes an error indication pin that signals
the host processor in the case of a single bit error-detection and
correction event.
To write to the device, take Chip Enables (CE1, CE2, and CE3
LOW) and Write Enable (WE) input LOW. If Byte Enable A (BA)
is LOW, then data from I/O pins (I/O0 through I/O7) is written into
the location specified on the address pins (A0 through A18). If
Byte Enable B (BB) is LOW, then data from I/O pins (I/O8 through
I/O15) is written into the location specified on the address pins
(A0 through A18). Likewise, BC and BD correspond with the I/O
pins I/O16 to I/O23 and I/O24 to I/O31, respectively.
To read from the device, take Chip Enables (CE1, CE2, and CE3
LOW) and Output Enable (OE) LOW while forcing the Write
Enable (WE) HIGH. If the first BA is LOW, then data from the
memory location specified by the address pins appear on I/O0 to
I/O7. If BB is LOW, then data from memory appears on I/O8 to
I/O15. Likewise, BC and BD correspond to the third and fourth
bytes. See Truth Table – CY7C1062G/CY7C1062GE on page 15
for a complete description of read and write modes.
The input and output pins (I/O0 through I/O31) are placed in a
high-impedance state when the device is deselected (CE1, CE2,
or CE3 HIGH), the outputs are disabled (OE HIGH), the byte
selects are disabled (BA-D HIGH), or during a write operation
(CE1, CE2 and CE3 LOW and WE LOW).
On the CY7C1062GE device, the detection and correction of a
single-bit error in the accessed location is indicated by the
assertion of the ERR output (ERR = High)[1].
CY7C1062G and CY7C1062GE devices are available in Pb-free
119-ball plastic ball grid array (PBGA) package.
