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
A29L004 Series
512K X 8 Bit CMOS 3.0 Volt-only,
Boot Sector Flash Memory
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
n Package options
- 40-pin TSOP (forward type), 32-pin PLCC or (s)TSOP
(forward type)
