128 or 256 Mbit (×16, multiple bank, multilevel interface, burst)
1.8 V supply Flash memories
Preliminary Data
Features
Supply voltage
– VDD = 1.7 V to 2.0 V for program, erase and
read
– VDDQ = 1.7 V to 2.0 V for I/O buffers
– VPP = 9 V for fast program
Synchronous/asynchronous read
– Synchronous burst read mode:
54 MHz, 66 MHz
– Asynchronous page read mode
– Random access: 70 ns, 85 ns
Synchronous burst read suspend
Programming time
– 2.5 µs typical word program time using
Buffer Enhanced Factory Program
command
Memory organization
– Multiple bank memory array:
8 Mbit banks for the M58LR128KT/B
16 Mbit banks for the M58LR256KT/B
– Parameter blocks (top or bottom location)
Dual operations
– Program/erase in one bank while read in
others
– No delay between read and write
operations
Block locking
– All blocks locked at power-up
– Any combination of blocks can be locked
with zero latency
– WP for block lock-down
– Absolute write protection with VPP = VSS
Not packaged separately
Security
– 64 bit unique device number
– 2112 bit user programmable OTP cells
Common Flash interface (CFI)
100 000 program/erase cycles per block
Electronic signature
– Manufacturer code: 20h
– Top device codes:
M58LR128KT: 88C4h
M58LR256KT: 880Dh
– Bottom device codes
M58LR128KB: 88C5h
M58LR256KB: 880Eh
The M58LRxxxKT/B memories are only available as part of a multichip package.
