A29L400A Series
512K X 8 Bit / 256K X 16 Bit CMOS 3.0 Volt-only,
Preliminary
Features
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
Access times:

Current:
- 4 mA typical active read current
- 20 mA typical program/erase current
-
200 nA typical CMOS standby
-
200 nA Automatic Sleep Mode current
Flexible sector architecture
-
16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX7 sectors
-
8 Kword/ 4 KwordX2/ 16 Kword/ 32 KwordX7 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
Extended operating temperature range: -40°C ~ +85°C
for –U series
Unlock Bypass Program Command
- Reduces overall programming time when issuing
multiple program command sequence
Top or bottom boot block configurations available
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
Typical 100,000 program/erase cycles per sector
20-year data retention at 125°C
-
Reliable operation for the life of the system
Compatible with JEDEC-standards
- Pinout and software compatible with single-power-
supply Flash memory standard
-
Superior inadvertent write protection
Data
Polling and toggle bits
-
Provides a software method of detecting completion of
program or erase operations
Ready /
BUSY
pin (RY /
BY
)
- Provides a hardware method of detecting completion of
program or erase operations
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
Hardware reset pin (
RESET
)
-
Hardware method to reset the device to reading array
data
Package options
-
44-pin SOP or 48-pin TSOP (I) or 48-ball TFBGA
