HY29LV400
4 Mbit (512K x 8/256K x 16) Low Voltage Flash Memory
KEY FEATURES
n Single Power Supply Operation
â Read, program and erase operations from
2.7 to 3.6 volts
â Ideal for battery-powered applications
n High Performance
â 70 and 90 ns access time versions for full
voltage range operation
â 55 ns access time version for operation
from 3.0 to 3.6 volts
n Ultra-low Power Consumption (Typical
Values)
â Automatic sleep mode current: 0.2 µA
â Standby mode current: 0.2 µA
â Read current: 7 mA (at 5 Mhz)
â Program/erase current: 15 mA
n Flexible Sector Architecture:
â One 16 KB, two 8 KB, one 32 KB and
seven 64 KB sectors in byte mode
â One 8 KW, two 4 KW, one 16 KW and
seven 32 KW sectors in word mode
â Top or bottom boot block configurations
available
n Sector Protection
â Allows locking of a sector or sectors to
prevent program or erase operations
within that sector
â Sectors lockable in-system or via
programming equipment
â Temporary Sector Unprotect allows
changes in locked sectors (requires high
voltage on RESET# pin)
n Fast Program and Erase Times
â Sector erase time: 0.5 sec typical for each
sector
â Chip erase time: 5 sec typical
â Byte program time: 9 µs typical
â Word program time: 11 µs typical
n Unlock Bypass Program Command
â Reduces programming time when issuing
multiple program command sequences
n Automatic Erase Algorithm Preprograms
and Erases Any Combination of Sectors
or the Entire Chip
n Automatic Program Algorithm Writes and
Verifies Data at Specified Addresses
n Minimum 100,000 Write Cycles per Sector
n Compatible With JEDEC standards
â Pinout and software compatible with
single-power supply Flash devices
â Superior inadvertent write protection
n Data# Polling and Toggle Bits
â Provide software confirmation of
completion of program and erase
operations
n Ready/Busy# Pin
â Provides hardware confirmation of
completion of program and erase
operations
n Erase Suspend/Erase Resume
â Suspends an erase operation to allow
reading data from, or programming data
to, a sector that is not being erased
â Erase Resume can then be invoked to
complete suspended erasure
n Hardware Reset Pin (RESET#) Resets the
Device to Reading Array Data
n Space Efficient Packaging
â 48-pin TSOP and 48-ball FBGA packages
