HY29F080
8 Megabit (1M x 8), 5 Volt-only, Flash Memory
KEY FEATURES
n
5 Volt Read, Program, and Erase
鈥?Minimizes system-level power
requirements
n
High Performance
鈥?Access times as fast as 70 ns
n
Low Power Consumption
鈥?15 mA typical active read current
鈥?30 mA typical program/erase current
鈥?5 碌A(chǔ) maximum CMOS standby current
n
Compatible with JEDEC Standards
鈥?Package, pinout and command-set
compatible with the single-supply Flash
device standard

protection
n
Sector Erase Architecture
鈥?Sixteen equal size sectors of 64K bytes
each
鈥?A command can erase any combination of
sectors
鈥?Supports full chip erase
n
Erase Suspend/Resume
鈥?Temporarily suspends a sector erase
operation to allow data to be read from, or
programmed into, any sector not being
erased
n
Sector Group Protection
鈥?Sectors may be locked in groups of two to
prevent program or erase operations
within that sector group
n
Temporary Sector Unprotect
鈥?Allows changes in locked sectors
(requires high voltage on RESET# pin)
n
Internal Erase Algorithm
鈥?Automatically erases a sector, any
combination of sectors, or the entire chip

LOGIC DIAGRAM
GENERAL DESCRIPTION
The HY29F080 is an 8 Megabit, 5 volt-only CMOS
Flash memory organized as 1,048,576 (1M) bytes
of eight-bits each. The device is offered in indus-
try-standard 44-pin PSOP and 40-pin TSOP pack-
ages.
The HY29F080 can be programmed and erased
in-system with a single 5-volt V
CC
supply. Inter-
nally generated and regulated voltages are pro-
vided for program and erase operations, so that
the device does not require a high voltage power
supply to perform those functions. The device can
also be programmed in standard EPROM pro-
grammers. Access times as fast as 70ns over the
full operating voltage range of 5.0 volts 鹵 10% are
offered for timing compatibility with the zero wait
state requirements of high speed microprocessors.
