A29L004 Series
512K X 8 Bit CMOS 3.0 Volt-only,
Preliminary
Features
n
Single power supply operation
- Full voltage range: 2.7 to 3.6 volt read and write
operations for battery-powered applications
- Regulated voltage range: 3.0 to 3.6 volt read and write
operations for compatibility with high performance 3.3
volt microprocessors
n
Access times:
- 70/90 (max.)
n
Current:
- 4 mA typical active read current
- 20 mA typical program/erase current
-
200 nA typical CMOS standby
-
200 nA Automatic Sleep Mode current
n
Flexible sector architecture
-
16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX7 sectors
-
Any combination of sectors can be erased
-
Supports full chip erase
-
Sector protection:
A hardware method of protecting sectors to prevent
any inadvertent program or erase operations within
that sector. Temporary Sector Unprotect feature
allows code changes in previously locked sectors
n
Unlock Bypass Program Command
- Reduces overall programming time when issuing
multiple program command sequence
n
Top or bottom boot block configurations available
n
Embedded Algorithms
- Embedded Erase algorithm will automatically erase
the entire chip or any combination of designated
sectors and verify the erased sectors
- Embedded Program algorithm automatically writes
and verifies data at specified addresses
n
Typical 100,000 program/erase cycles per sector
n
20-year data retention at 125°C
-
Reliable operation for the life of the system
n
Compatible with JEDEC-standards
- Pinout and software compatible with single-power-
supply Flash memory standard
-
Superior inadvertent write protection
n
Data
Polling and toggle bits
-
Provides a software method of detecting completion
of program or erase operations
n
Ready /
BUSY
pin (RY /
BY
)
- Provides a hardware method of detecting completion
of program or erase operations (not available on 32-
pin PLCC & (s)TSOP packages)
n
Erase Suspend/Erase Resume
-
Suspends a sector erase operation to read data from,
or program data to, a non-erasing sector, then
resumes the erase operation
n
Hardware reset pin (
RESET
)
-
Hardware method to reset the device to reading array
data (not available on 32 pin PLCC & (s)TSOP
packages)
n
Package options
-
