32-Mbit W18 + 8-Mbit SRAM (38F1020W0YTQ1, 38F1020W0YBQ1)

Intel StrataFlash Wireless Memory (W18 SCSP)

Order Number: 252635, Revision: 003
ADV#
Input
FLASH ADDRESS VALID:
During synchronous reads, flash device addresses latch on the ADV# rising
edge or on a CLK transition with ADV# low.
For asynchronous reads, either drive ADV# high to latch an address or hold
ADV# low throughout the read cycle.
CLK
Input
FLASH CLOCK: CLK synchronizes the flash device to the system bus frequency.
Used only for burst reads, CLK increments the internal address generator within the
flash device. If ADV# is asserted low, the flash device uses a CLK transition to latch
externally-applied addresses .
WAIT
Output
FLASH WAIT: Indicates that the flash memory DOUT is not yet valid. Used only for
synchronous reads. WAIT is high-Z if CE#1 is deasserted, but is not gated by OE#1.
WP#
Input
FLASH WRITE PROTECT: Enables/disables the flash lock-down mechanism. WP#-
low secures locked-down blocks from software unlock attempts. WP#-high overrides
the lock-down function, thus allowing system software to unlock locked-down blocks.
VPP
Power
FLASH PROGRAM/ERASE SUPPLY: Hardware program and erase protection. A
valid voltage level allows program or erase; memory contents cannot be altered
when VPP is at or below the VPP lockout voltage (VPPLK).
Do not attempt program or erase at invalid VPP voltages. Set VPP = VCC for in-
system read, program and erase operations. VPP must remain above VPP1MIN for in-
system program or erase operations.
VPP2 can be applied to main blocks for 1000 cycles maximum and to parameter
blocks for 2500 cycles. VPP can be VPP2 for cumulative total, not to exceed 80 hours
maximum. Extended use of VPP at VPP2 might reduce block cycling capability.
VCC
Power
FLASH POWER SUPPLY: Supplies power to the flash core.
S-VCC
Power
SRAM POWER SUPPLY: Supplies power for SRAM operations.
VSS
Power
GROUND: Do not float any VSS connection.
