A29DL16x Series
16 Megabit (2M x 8-Bit/1M x 16-Bit) CMOS 3.0 Volt-only,
Simultaneous Operation Flash Memory
Preliminary
DISTINCTIVE CHARACTERISTICS
ꢀ
Polling and Toggle Bits
- Provides a software method of detecting the status of
program or erase cycles
Data
ARCHITECTURAL ADVANTAGES
ꢀSimultaneous Read/Write operations
- Data can be continuously read from one bank while
executing erase/program functions in other bank
- Zero latency between read and write operations
ꢀMultiple bank architectures
ꢀUnlock Bypass Program command
- Reduces overall programming time when issuing
multiple program command sequences
- Three devices available with different bank sizes (refer to
Table 2)

to reading array data
ꢀ
/ACC input pin
WP
- Write protect (
) function allows protection of two
WP
outermost boot sectors, regardless of sector protect
status
- Acceleration (ACC) function accelerates program timing
PERFORMANCE CHARACTERISTICS
ꢀHigh performance
- Access time as fast as 70ns
- Program time: 7µs/word typical utilizing Accelerate
function
ꢀSector protection
- Hardware method of locking a sector, either in-system or
using programming equipment, to prevent any program
or erase operation within that sector
- Temporary Sector Unprotect allows changing data in
protected sectors in-system
ꢀUltra low power consumption (typical values)
- 2mA active read current at 1MHz
- 10mA active read current at 5MHz
- 200nA in standby or automatic sleep mode
ꢀMinimum 1 million write cycles guaranteed per sector
ꢀ20 Year data retention at 125°C
- Reliable operation for the life of the system
SOFTWARE FEATURES
ꢀSupports Common Flash Memory Interface (CFI)
ꢀErase Suspend/Erase Resume
- Suspends erase operations to allow programming in
same bank
ꢀSoftware temporary sector/sector block unprotect command
ꢀSoftware sector protect/unprotect command
